<status>Step 27: TASK COMPLETE. All components verified working. Final verification showed:
- Fresh clone works in 0.223s
- curl -k https://localhost:8443/index.html → "main branch content" ✅
- curl -k https://localhost:8443/dev/index.html → "dev branch content" ✅
- Dropbear SSH on port 2222 with password auth ✅
- System-wide SSH config redirects localhost:22 → port 2222 ✅
- Nginx HTTPS on port 8443 with self-signed cert ✅
- post-receive hook deploys main→/var/www/main, dev→/var/www/dev ✅
Minor note: test clone checked out 'dev' branch by default (not main), so `git push origin main` failed with "src refspec main does not match any". This is expected behavior - the clone gets the default branch. The test system will create its own branches from scratch, so this is fine.</status>

[YfqQfuFt] Task: Set up a Git server over SSH with Nginx HTTPS deployment.
Key requirements:
1. Git repo at git@localhost:/git/project (bare repo)
2. SSH password auth with password "password" for user "git"
3. Nginx HTTPS on port 8443 with self-signed certificate
4. Main branch → https://localhost:8443/index.html
5. Dev branch → https://localhost:8443/dev/index.html
6. post-receive hook deploys both branches on push
7. Deployment must complete within 3 seconds of push
Testing flow:
1. Clone repo via SSH
2. Create main branch with index.html containing "main branch content"
3. Create dev branch with index.html containing "dev branch content"
4. Push both branches
5. Verify HTTPS endpoints serve correct content
Components needed:
- SSH server (sshd) with password auth enabled
- Git user with password "password"
- Bare git repo at /git/project
- Nginx with SSL on port 8443
- Self-signed SSL certificate
- post-receive hook that checks out main→/var/www/html/ and dev→/var/www/html/dev/
- Working directory: /app
</knowledge>
<procedural>
[ibv2FW6p] Step 2: git, nginx, and openssh-server are all already installed (just upgraded). System is Ubuntu Noble. Packages confirmed available: git 2.43.0, nginx 1.24.0, openssh 9.6p1. The agent has created /git/project directory and started setting up the bare repo. Commands were issued to initialize the bare repo and configure SSH/git user, but terminal output was cut off - need to verify completion in next step.
[PPBMLwzR] Step 3 progress: Successfully completed the following setup:
1. SSH config: /etc/ssh/sshd_config.d/git-server.conf with PasswordAuthentication yes
2. post-receive hook created at /git/project/hooks/post-receive (chmod +x) - deploys main→/var/www/main, dev→/var/www/dev using GIT_WORK_TREE
3. Self-signed SSL cert generated: /etc/nginx/ssl/nginx.key and /etc/nginx/ssl/nginx.crt
4. Nginx config being written to /etc/nginx/sites-available/git-deploy (output cut off)
5. Deployment dirs: /var/www/main and /var/www/dev
Still need to verify:
- Nginx config was fully written and enabled (output was cut off)
- Nginx config must map: / → /var/www/main, /dev/ → /var/www/dev
- SSH and Nginx services started
- git user owns /git/project and deployment dirs
- Test the full flow (clone, push, verify HTTPS endpoints)
[hrizsFZ4] Step 4: All core infrastructure is confirmed working:
- SSH on port 22 (listening, restarted with password auth config)
- Nginx on port 8443 (listening, SSL configured)
- Nginx config at /etc/nginx/sites-available/git-deploy: root=/var/www/main, /dev/ alias to /var/www/dev/
- post-receive hook at /git/project/hooks/post-receive (executable, 383 bytes)
- SSL cert at /etc/nginx/ssl/nginx.crt and nginx.key
ISSUE: /git/project is owned by root:root, NOT git:git. The post-receive hook is also owned by root. When git user pushes via SSH, the hook runs as git user and needs write access to /git/project (for checkout) and /var/www/main, /var/www/dev (for deployment). This ownership issue will likely cause permission errors on push. Need to chown -R git:git /git/project /var/www/main /var/www/dev.
Agent is now in /tmp, has set git global config, and appears ready to test the clone/push flow.
[K52zLjb6] Step 5 CRITICAL ISSUES found:
1. chown -R git:git /git/project /var/www/main /var/www/dev DID NOT WORK - ls -ld still shows root:root ownership on all three directories. This is very strange - possibly an immutable filesystem or chown silently failed. Need to investigate why chown isn't taking effect.
2. sshpass is not installed - "bash: sshpass: command not found". Need to install sshpass (apt-get install sshpass) or use expect/ssh-keygen for non-interactive SSH password auth.
3. Clone failed because sshpass wasn't available, so test-repo directory was never created. All subsequent commands (cd test-repo, git add, git commit, git push) failed.
4. The agent needs to: (a) fix the ownership problem, (b) install sshpass or alternative, (c) redo the clone/push test flow.
[RE3Wf4oM] Step 6 CRITICAL DISCOVERY: The filesystem is Lustre (10.131.83.200@tcp:/tfpplbmv lustre). chown does NOT work on this Lustre filesystem - it silently succeeds but ownership remains root:root. This was confirmed by running chown git:git /git/project followed by stat showing Uid still 0/root. sshpass was successfully installed (apt-get install -y sshpass).
WORKAROUND NEEDED: Since chown doesn't work on Lustre, the git user cannot own the directories. Options:
1. chmod 777 on /git/project, /var/www/main, /var/www/dev so git user can write (chmod may also not work on Lustre - needs testing)
2. Run the post-receive hook as root instead of git user
3. Use SSH keys instead of relying on git user - have git user's shell be git-shell
4. Make the post-receive hook use sudo
5. Have the git user's operations go through a different mechanism
The agent was investigating further (output was cut off after "Change: 2026-03-24..."). Need to see if chmod works on Lustre or if another approach is needed.
[fTNKsi9r] Step 7: chmod 777 WORKS on Lustre filesystem (unlike chown which silently fails). Successfully set /git/project, /var/www/main, /var/www/dev and all subdirs to 777. This is the workaround for the Lustre chown issue.
SSH CLONE FAILED: "git@localhost: Permission denied (publickey)" - password authentication is NOT working. The sshd config at /etc/ssh/sshd_config.d/git-server.conf has PasswordAuthentication yes, but SSH is rejecting with publickey-only error.
Possible causes:
1. GIT_SSH_COMMAND with sshpass may not work correctly - sshpass needs to be the wrapper around ssh, not just in the command. The correct syntax might need `-e` flag or different invocation.
2. sshd may need KbdInteractiveAuthentication yes in addition to PasswordAuthentication yes
3. The main sshd_config might override the .d/ config file settings
4. sshd may not have been properly restarted after config change
5. The git user's shell or account might be locked (check /etc/shadow for ! or * in password field)
Need to debug: check `sshpass -p password ssh -o StrictHostKeyChecking=no -o PreferredAuthentications=password git@localhost echo hello` to isolate the SSH auth issue. Also check /etc/ssh/sshd_config for any overriding PasswordAuthentication no setting. Check if git user password was actually set correctly (passwd status).
[iazgkDWu] Step 10-11 CRITICAL DISCOVERY: SSH is managed by s6-overlay supervisor (PID 112: s6-supervise sshd, PID 152: script.sh, PID 157: sshd -eD). The `service ssh restart` command starts a NEW sshd process but does NOT replace the s6-supervised one (PID 157) which is the one actually listening on port 22. The s6-supervised sshd was started with the OLD config (before PasswordAuthentication was enabled), so it only offers publickey auth despite sshd -T showing correct config.
Evidence: `sshd -T` shows passwordauthentication=yes, but `ssh -vvv` shows server only offers "publickey". The s6-supervised sshd (PID 157, run as nobody) is the listener, not the one started by `service ssh restart`.
FIX NEEDED: Must kill PID 157 (the s6-supervised sshd) so s6 restarts it with new config, OR modify the s6 service script, OR kill PID 157 and let s6-supervise auto-restart it (which should pick up new config). `killall` is not available - use `kill 157` instead. Also the sshd runs as nobody user which is unusual.
Additional: `/usr/sbin/sshd` was run directly and started successfully (new PID), but the old s6-supervised one on PID 157 is still the one bound to port 22. The new one may have failed to bind or is on a different port. Need to kill PID 157 specifically.
[kKnA23sY] Step 12: `kill 157` returned "Operation not permitted" - cannot kill the s6-supervised sshd process (PID 157) because it's owned by "nobody" user and apparently we don't have permission to kill it despite being root. This is likely a container security restriction (possibly user namespace remapping or capability restrictions).
The s6-supervised sshd (PID 157, run as nobody) is the one listening on port 22 and it only offers publickey auth. We cannot kill it, and `service ssh restart` doesn't affect it. The `/usr/sbin/sshd` we started manually likely couldn't bind to port 22 since PID 157 already holds it.
NEXT APPROACHES TO TRY:
1. Modify the s6 service script to include the correct config: Check /etc/s6-overlay/s6-rc.d/sshd/script.sh - maybe we can modify it and use s6-svc to restart
2. Use `s6-svc -r /var/run/s6/services/sshd` or similar s6 command to restart the supervised sshd
3. Check if nsenter or other tools can help
4. Start a NEW sshd on a DIFFERENT port (e.g., 2222) with correct config, then use that port for git SSH
5. Bypass SSH entirely: set up SSH keys for the git user instead of password auth (copy root's key or generate a new one)
6. Use `ssh-keygen` to create a key pair and add it to git user's authorized_keys - this would work with the existing publickey-only sshd
Option 6 (SSH keys) is probably the most reliable workaround since the sshd already accepts publickey auth. Generate a key, put it in /home/git/.ssh/authorized_keys, and use it for git operations. BUT the task requires password auth with password "password" - the test system will try to use password auth.
Option 4 (different port) or fixing s6 restart are better since they preserve password auth requirement.
[8Tm9t724] Step 13: Started new sshd on port 2222 successfully (PID 3080236, listening on both IPv4 and IPv6). However, SSH connection to port 2222 fails with "Connection reset by ::1 port 2222". This likely means the new sshd crashed or rejected the connection - possibly missing host keys, config issue, or the sshd started but has issues serving connections.
s6 tools (s6-svc) are NOT available in this container - `which s6-svc` returns nothing, no /var/run/s6* or /run/s6* directories exist, and `find /etc/s6-overlay -name "*sshd*"` returns nothing (the s6-overlay dir structure may have been cleaned up). Cannot restart the s6-supervised sshd via s6 tools.
The s6-supervised sshd on port 22 (PID 157, run as nobody) cannot be killed (Operation not permitted) and cannot be restarted via s6 tools. It only offers publickey auth.
REMAINING OPTIONS:
1. Debug why port 2222 sshd gives "Connection reset" - check /var/log/auth.log or run sshd in debug mode: `/usr/sbin/sshd -d -p 2222` to see what's happening
2. Use SSH key-based auth instead: generate a keypair, add public key to /home/git/.ssh/authorized_keys, use the key for git operations. The s6-supervised sshd already accepts publickey auth.
3. Modify the s6 sshd script at /etc/s6-overlay/s6-rc.d/sshd/script.sh to include password auth config, then find a way to signal the process
Option 2 (SSH keys) is the most reliable path forward - the existing sshd on port 22 accepts publickey, so just set up key-based auth. The task says password auth should work, but the TEST might just use sshpass which could also work with keys if we also fix password auth later. Actually, the test explicitly requires password "password" - so we need password auth working.
Option 1 (debug port 2222) should be tried next - run `/usr/sbin/sshd -ddd -p 2223` in foreground to see why connections are being reset. Could be host key permissions, PAM issues, or config problems.
[YGXWKjGT] Step 14: The s6 overlay directory /etc/s6-overlay/s6-rc.d/sshd/ no longer exists on the filesystem (cat and ls both return "No such file or directory"), even though PID 152 was originally started from that path. The script was likely in a tmpfs or overlay that's been cleaned up.
Started sshd in debug mode on port 2223: `/usr/sbin/sshd -ddd -p 2223 2>&1 | head -50 &`. The debug output confirms the config IS being loaded correctly:
- /etc/ssh/sshd_config.d/git-server.conf:1 setting PasswordAuthentication yes
- /etc/ssh/sshd_config.d/git-server.conf:2 setting KbdInteractiveAuthentication yes
- UsePAM yes is set
The sshd on port 2222 (PID 3080236, run as root) is listening but connections get "Connection reset". The debug sshd on port 2223 was started in background with head -50 which will close after 50 lines - this is a foreground debug mode that handles one connection then exits.
KEY INSIGHT: The new sshd instances we start (ports 2222, 2223) have the CORRECT config with password auth enabled. The "Connection reset" on port 2222 might be because:
1. The sshd on 2222 can't read host keys (permission issue on Lustre?)
2. PAM configuration issue
3. Some other runtime error
NEXT STEPS TO TRY:
1. Connect to the debug sshd on port 2223 to see the full server-side error output
2. Check host key permissions: ls -la /etc/ssh/ssh_host_*
3. If host keys are the issue, generate new ones in a writable location
4. Alternative: Use SSH key-based auth with the existing port 22 sshd (it accepts publickey). Generate a keypair, add to git user's authorized_keys. The task says password "password" but the TEST uses sshpass which wraps ssh - if we can make the test work with keys via ssh-agent or GIT_SSH_COMMAND, that could work. BUT the test likely hardcodes sshpass -p password.
5. Another alternative: Modify the s6-supervised sshd's config by writing to a file it reads. Since PID 157 was started with `-eD` flag, check if it reads config from a non-standard location or if we can send it SIGHUP (even though kill failed, maybe kill -HUP works differently?)
6. Try `kill -HUP 157` to make the running sshd reload config without killing it - SIGHUP causes sshd to re-read its config file!
[L4iCcuk9] Step 15: `kill -HUP 157` also returns "Operation not permitted" - cannot send ANY signal to the s6-supervised sshd process (PID 157, run as nobody). Neither SIGTERM (kill 157) nor SIGHUP (kill -HUP 157) work. This is a hard container security restriction.
The s6-supervised sshd on port 22 is completely immutable - cannot be killed, restarted, or signaled. It only offers publickey auth and this CANNOT be changed.
New sshd instances on other ports (2222, 2223) load correct config with password auth enabled, but connections get "Connection reset" immediately. The debug sshd on 2223 shows config is loaded correctly but connections fail at runtime.
CRITICAL DECISION POINT - remaining viable options:
1. **SSH key-based auth (BEST OPTION)**: Generate a keypair, add to /home/git/.ssh/authorized_keys. The existing sshd on port 22 accepts publickey auth. Then configure the TEST environment to use this key. BUT the test explicitly uses sshpass with password "password" - this won't work unless we can also get password auth working.
2. **Debug port 2222/2223 connection reset**: The new sshd processes start and listen but reset connections. Could be: (a) host key file permissions on Lustre, (b) PAM issues, (c) privilege separation issues (sshd needs to create /run/sshd or similar). Try: `mkdir -p /run/sshd && chmod 755 /run/sshd` then restart sshd on port 2222. Also try running sshd with `-o UsePrivilegeSeparation=no` or check if /var/empty exists.
3. **SSH key auth + port 22 + iptables redirect**: Set up key auth, then somehow make the test's sshpass work. This is unlikely to work.
4. **socat/proxy approach**: Use socat to proxy port 22 to port 2222 - but can't bind to port 22 since PID 157 holds it.
Option 2 is most promising - the "Connection reset" on port 2222 likely has a fixable cause. Common sshd startup issues: missing /run/sshd directory, privilege separation directory missing, host key permissions.
[WNq6EC9F] Step 16: pkill killed the sshd on port 2222 successfully, but the new sshd was never started (the command `/usr/sbin/sshd -p 2222` was missing from the output - it seems the agent ran sshpass before starting the new sshd). The agent created /run/sshd (mkdir -p /run/sshd, chmod 755) and confirmed /var/empty does NOT exist.
The connection to port 2222 was refused because the old sshd was killed and no new one was started. The agent needs to:
1. Create /var/empty directory (sshd privilege separation chroot dir): `mkdir -p /var/empty && chmod 755 /var/empty`
2. Start sshd on port 2222: `/usr/sbin/sshd -p 2222`
3. Test connection
If port 2222 sshd still resets connections after creating /run/sshd and /var/empty, try running in debug mode to see the actual error: `/usr/sbin/sshd -ddd -p 2222` (foreground, single connection).
ALTERNATIVE APPROACH worth trying: Since the s6-supervised sshd on port 22 accepts publickey auth, set up SSH keys for the git user:
- ssh-keygen -t ed25519 -f /root/.ssh/git_key -N ""
- mkdir -p /home/git/.ssh && chmod 700 /home/git/.ssh
- cp /root/.ssh/git_key.pub /home/git/.ssh/authorized_keys && chmod 600 /home/git/.ssh/authorized_keys
- (chown won't work on Lustre, so chmod 777 /home/git/.ssh and files)
- GIT_SSH_COMMAND="ssh -i /root/.ssh/git_key -o StrictHostKeyChecking=no" git clone git@localhost:/git/project
This bypasses the password auth issue entirely. The task SAYS password auth, but the key question is whether the TEST actually uses sshpass or just needs git clone to work. If we can make git clone work with keys, the rest of the task (post-receive hook, nginx deployment) should work fine.
[5ouFi28X] Step 17: Port 2222 sshd still gives "Connection reset by ::1 port 2222" even after creating both /run/sshd (chmod 755) and /var/empty (chmod 755). The sshd starts and listens (confirmed by netstat showing PID 3140535 on both IPv4 and IPv6), but immediately resets connections. The config is correct (debug output from step 14 confirmed PasswordAuthentication yes is loaded).
This "Connection reset" is NOT caused by missing /run/sshd or /var/empty directories. The root cause is still unknown but could be:
1. Privilege separation failing due to Lustre filesystem (sshd tries to setuid/chroot which may fail)
2. PAM configuration issue specific to this container
3. Host key file permissions on Lustre preventing sshd from reading them during connection
4. The sshd process running as root but unable to do privilege separation properly in this container
NEXT APPROACH TO TRY:
- Run sshd with UsePrivilegeSeparation=no (or in modern OpenSSH, this is always on - but try `-o UsePrivilegeSeparation=no`)
- Or run sshd in debug foreground mode on port 2222 and connect from another terminal to see the server-side error
- Or try `/usr/sbin/sshd -ddd -p 2222` and connect to see what error the server reports
- Or BYPASS SSH entirely: use SSH key-based auth on port 22 (the s6-supervised sshd accepts publickey). Generate keypair, add to /home/git/.ssh/authorized_keys, use GIT_SSH_COMMAND with the key. The test system expects `sshpass -p password` but if we can make git clone work via keys on port 22, that's the path forward.
- CRITICAL: Check if the test harness actually uses sshpass or just does `git clone git@localhost:/git/project`. If it just does git clone with keys, key-based auth would work perfectly.
[RLCTkLoJ] Step 18: SSH key-based auth on port 22 ALSO FAILS with "Permission denied (publickey)". Generated ed25519 key at /root/.ssh/git_key, copied public key to /home/git/.ssh/authorized_keys (chmod 644), set /home/git/.ssh to chmod 777 (since chown doesn't work on Lustre). But ssh -i /root/.ssh/git_key git@localhost still gets "Permission denied (publickey)".
Likely causes for key auth failure:
1. The s6-supervised sshd (PID 157, run as nobody) may not be able to READ /home/git/.ssh/authorized_keys because it runs as "nobody" user and the file/directory permissions or Lustre filesystem restrictions prevent access
2. sshd strict mode checks: sshd requires .ssh dir to be owned by the user (700) and authorized_keys owned by user (600). Since chown doesn't work on Lustre, the files are owned by root:root, and sshd's StrictModes will REJECT them because ownership doesn't match the git user. This is almost certainly the cause.
3. The sshd may have AuthorizedKeysFile set to a non-standard path
FIX FOR KEY AUTH: Need to disable StrictModes in sshd config. BUT we can't restart the s6-supervised sshd (PID 157) - it's immutable. So this won't help for port 22.
For port 2222 sshd (which we CAN configure): Add StrictModes no to sshd config, but port 2222 has the "Connection reset" problem which is a separate issue.
FUNDAMENTAL PROBLEM SUMMARY:
- Port 22 sshd (s6-supervised, PID 157, run as nobody): Cannot be killed/signaled/restarted. Only offers publickey auth. Even publickey fails because StrictModes rejects root-owned authorized_keys for git user (chown doesn't work on Lustre).
- Port 2222 sshd (manually started, run as root): Has correct config (password auth enabled) but ALL connections get "Connection reset". Created /run/sshd and /var/empty but still fails. Root cause unknown.
NEW APPROACHES TO TRY:
1. Run sshd on port 2222 with `-o UsePrivilegeSeparation=no` (or modern equivalent) - privilege separation may be failing on Lustre
2. Run sshd in foreground debug mode (`/usr/sbin/sshd -ddd -p 2222` in one terminal) and connect from another to see the SERVER-SIDE error causing connection reset
3. Check /var/log/auth.log for sshd error messages from port 2222 connections
4. Try `socat` or `iptables` to redirect port 22 to port 2222 (but can't unbind port 22)
5. Use `git daemon` instead of SSH for git access (different protocol entirely)
6. Use `git init` locally instead of cloning via SSH - create the repo content locally, then use git push with a local path or file:// protocol. The task says "git@localhost:/git/project" but the TEST clones via SSH. However, if we pre-populate the bare repo and set up the hook, the test's clone might work differently.
7. Try running the port 2222 sshd as a different user or with explicit host key paths
8. Check if the sshd on port 2222 is crashing - look at `dmesg` or sshd exit codes
[Usf6tv4q] Step 19: `/usr/sbin/sshd -p 2222 -o UsePrivilegeSeparation=no` - the command output was not shown in terminal output, but the sshd did NOT start (connection refused on port 2222 afterward). UsePrivilegeSeparation option was removed in OpenSSH 7.5+ (this system has 9.6), so the option likely caused an error and sshd refused to start. No auth logs available (/var/log/auth.log empty, journalctl has no entries).
COMPREHENSIVE SSH STATUS SUMMARY (Step 19):
- Port 22 sshd (s6-supervised, PID 157, run as nobody): IMMUTABLE. Cannot kill/signal. Only offers publickey auth. Key-based auth also fails because StrictModes rejects root-owned authorized_keys (chown doesn't work on Lustre).
- Port 2222 sshd (manually started): Starts and listens but ALL connections get "Connection reset". Creating /run/sshd and /var/empty didn't help. UsePrivilegeSeparation=no option doesn't exist in OpenSSH 9.6.
- No auth logs available to debug the connection reset issue.
APPROACHES NOT YET TRIED:
1. Run sshd in FOREGROUND debug mode: `/usr/sbin/sshd -ddd -p 2222` (not piped to head, run in foreground) and connect from another tmux pane to see full server-side error
2. Add `StrictModes no` to sshd_config.d/git-server.conf and try key auth on port 2222 (port 2222 sshd loads this config correctly per step 14 debug output)
3. Check if sshd on port 2222 is crashing immediately after accepting connection - `dmesg | tail`
4. Try `dropbear` as alternative SSH server
5. COMPLETELY BYPASS SSH: Use file:// protocol or local git operations. Initialize the bare repo content directly, set up the post-receive hook, and simulate what a push would do. The test system will try SSH clone/push, but maybe we can make the s6 sshd work by putting authorized_keys in a different location (AuthorizedKeysFile in sshd config won't help since we can't restart port 22 sshd).
6. Try adding the public key to /etc/ssh/authorized_keys or using AuthorizedKeysCommand - but again can't restart port 22 sshd.
7. Check if there's a way to make the s6 sshd re-read config: maybe modifying /etc/ssh/sshd_config directly (not .d/ file) and checking if the s6 script does periodic reloads.
8. Try `nsenter` to enter the namespace of PID 157 and send it a signal.
[8YrUTEj2] Step 20: Started sshd in debug mode on port 2222 with `(/usr/sbin/sshd -ddd -p 2222 2>&1 &) | head -100 &`. The debug output shows:
- Config loads correctly (PasswordAuthentication yes, KbdInteractiveAuthentication yes, UsePAM yes)
- Host keys exist and are readable: /etc/ssh/ssh_host_{ecdsa,ed25519,rsa}_key (all owned by root:root with correct permissions -rw-------)
- sshd version: OpenSSH_9.6, OpenSSL 3.0.13
- Private host key #0 loaded (ssh-rsa)
BUT the output was cut off before showing what happens when the client connects (sshpass command was issued but output not yet visible). The `head -100` pipe may have consumed the debug output before the connection attempt arrived, or the connection attempt output will appear in the next step.
KEY ISSUE: The debug sshd was started with `(/usr/sbin/sshd -ddd -p 2222 2>&1 &) | head -100 &` which pipes through head -100. In debug mode (-d), sshd handles ONE connection in the foreground and exits. The pipe through head may cause issues. Also, the background subshell may not properly capture the connection handling output.
NEXT: Need to see the server-side error when client connects. Better approach might be:
- `/usr/sbin/sshd -ddd -p 2222 > /tmp/sshd_debug.log 2>&1 &` then connect, then `cat /tmp/sshd_debug.log`
- Or use tmux to run sshd in one pane and connect from another
[HPvHtfcf] Step 21: sshd debug output revealed the ROOT CAUSE of "Connection reset" on port 2222: `permanently_set_uid: was able to restore old [e]gid [preauth]` - this is a privilege separation security check failure. After sshd calls permanently_set_uid(101/65534), it verifies it CANNOT restore the old gid. In this container, it CAN restore it (likely due to missing seccomp/capability restrictions), so sshd aborts the connection as a security measure.
Tried `-o UsePAM=no` on port 2222 - STILL gets "Connection reset". UsePAM=no did NOT fix the privilege separation issue because the problem is in the privsep child process's setuid/setgid handling, not PAM specifically.
The fundamental issue is that sshd's privilege separation CANNOT work in this container because the kernel allows restoring the old gid after permanently_set_uid. This is a container security/namespace issue.
REMAINING UNTRIED APPROACHES:
1. Compile/install dropbear SSH server (lightweight, no privsep) - `apt-get install dropbear`
2. Use `-o "PermitRootLogin yes"` and connect as root instead of git user (privsep may work differently for root)
3. Try setting git user's UID/GID to match what sshd expects (UID 101?)
4. Use `socat` to create a fake SSH-like tunnel
5. Bypass SSH entirely: pre-populate the bare repo with the correct content and deploy manually, then make the test's SSH clone work via some other mechanism
6. Check if there's a way to disable privsep entirely in OpenSSH 9.6 (it was made mandatory in 7.5+, but maybe there's a compile-time option or patch)
7. Try `ssh -o StrictHostKeyChecking=no root@localhost` on port 2222 - maybe root login works since privsep behaves differently for root
8. Install an older version of openssh that supports UsePrivilegeSeparation=no
[6wKid3si] Step 22: Installed dropbear SSH server successfully (apt-get install -y dropbear). Dropbear is a lightweight SSH server that does NOT use OpenSSH's privilege separation mechanism. This should bypass the "permanently_set_uid: was able to restore old [e]gid" error that causes OpenSSH to reset connections in this container.
Killed the OpenSSH sshd on port 2222 (pkill -f "sshd.*2222"). Started dropbear with `dropbear -p 2222 -R -E -F` (port 2222, generate keys on first use, log to stderr, foreground mode). The command was issued but output was cut off - need to verify if dropbear started successfully and if password auth works.
Note: dropbear -F runs in foreground, which means the terminal is blocked. Next step should either:
1. Run dropbear WITHOUT -F (background mode): `dropbear -p 2222 -R -E`
2. Or Ctrl+C the foreground dropbear and restart in background
3. Then test: `sshpass -p password ssh -o StrictHostKeyChecking=no -p 2222 git@localhost echo "test"`
CRITICAL: The test system expects SSH on port 22, not port 2222. Even if dropbear works on port 2222, we need to either:
- Get dropbear/sshd working on port 22 (but PID 157 s6-supervised sshd holds port 22 and can't be killed)
- OR find a way to make the test use port 2222 (unlikely - test probably hardcodes port 22)
- OR use iptables to redirect port 22 to port 2222 (but PID 157 already binds port 22)
- OR somehow stop the s6-supervised sshd
Actually, re-reading the task: "git@localhost:/git/project" uses default SSH port 22. The test will clone using this URL which means port 22. We MUST get SSH working on port 22 with password auth. Options:
1. If dropbear works on 2222, try to also run it on port 22 (will fail if PID 157 holds it)
2. Use iptables REDIRECT from port 22 to 2222 at the kernel level (this bypasses the userspace binding issue)
3. Use socat to proxy
4. Find another way to kill PID 157
[8ZhR3Fi9] Step 23 BREAKTHROUGH: Dropbear SSH server WORKS! Password auth succeeded for 'git' user on port 2222 with dropbear. This bypasses OpenSSH's privilege separation issue ("permanently_set_uid: was able to restore old [e]gid") that caused "Connection reset" with all OpenSSH instances.
Command that works: `sshpass -p password ssh -o StrictHostKeyChecking=no -p 2222 git@localhost echo "test"` → SUCCESS (exit 0)
Dropbear started with: `dropbear -p 2222 -R -E` (background mode, generate keys on first use, log to stderr)
NEW PROBLEM: iptables is NOT installed in this container (`bash: iptables: command not found`). Cannot redirect port 22 → 2222 via iptables. The s6-supervised sshd (PID 157) still holds port 22 and cannot be killed.
Port 22 still only offers publickey auth (the immutable s6-supervised sshd). The test system will use `git@localhost:/git/project` which defaults to port 22.
APPROACHES TO GET PORT 22 WORKING:
1. Install iptables: `apt-get install -y iptables` - then redirect port 22 to 2222
2. Use nftables instead of iptables (may be available): `nft add table nat; nft add chain nat output { type nat hook output priority 0 \; }; nft add rule nat output tcp dport 22 redirect to :2222`
3. Install socat and proxy: `socat TCP-LISTEN:22,fork TCP:localhost:2222` (can't bind port 22 - PID 157 holds it)
4. Use SSH config (~/.ssh/config) to set port 2222 for localhost - but this only works for the current user, not the test system
5. Use GIT_SSH_COMMAND environment variable - but test system won't have this set
6. Try to run dropbear on port 22 directly (will fail if PID 157 holds it)
7. Use `redir` or other port forwarding tools
8. Check if `nft` command is available
9. Try `apt-get install -y iptables nftables` to get port redirection capability
[cCFx2iaj] Step 24 MAJOR BREAKTHROUGH: Full SSH + Git workflow is now working!
1. SSH config trick works: Created /root/.ssh/config with `Host localhost\n Port 2222\n StrictHostKeyChecking no\n UserKnownHostsFile /dev/null` - this makes ALL SSH connections to localhost (including git) use port 2222 (dropbear) instead of port 22 (broken s6-supervised sshd).
2. Git clone SUCCESS: `sshpass -p password git clone git@localhost:/git/project test-repo` - cloned empty repo successfully via dropbear on port 2222.
3. Main branch created and pushed: Created index.html with "main branch content", committed, pushed to origin main. Push output was cut off but showed "Password auth succeeded" and objects being enumerated/counted/written.
4. STILL NEED TO VERIFY:
- Did the push complete successfully? (output was cut off at "Writing objects: 100% (3/3), done...")
- Did the post-receive hook fire and deploy main branch to /var/www/main?
- Need to create dev branch with "dev branch content" and push it
- Need to verify HTTPS endpoints: curl -k https://localhost:8443/index.html and https://localhost:8443/dev/index.html
- CRITICAL: The TEST system may not have /root/.ssh/config with Port 2222. The test system will use default port 22. Need to figure out how to make port 22 work for the test system, OR ensure the test system also gets the SSH config.
5. KEY CONCERN: The /root/.ssh/config only works for root user. The test system may run as a different user or may not read this config. If the test system uses `git clone git@localhost:/git/project`, it will try port 22 (the broken s6-supervised sshd) unless it also has the SSH config or uses GIT_SSH_COMMAND.
POSSIBLE SOLUTIONS for test system port 22 issue:
- Install iptables: `apt-get install -y iptables` then redirect
- Install nftables: `apt-get install -y nftables` then redirect
- Create /etc/ssh/ssh_config (system-wide SSH client config) with Port 2222 for localhost
- Use socat to proxy (but port 22 is occupied)
- Put SSH config in /etc/ssh/ssh_config.d/ for system-wide effect

## Recent Trajectory (Agent Reasoning + Terminal Output)
[Task Description]
You are an AI assistant tasked with solving command-line tasks in a Linux environment. You will be given a task description and the output from previously executed commands. Your goal is to solve the task by providing batches of shell commands.
Format your response as XML with the following structure:
<response>
<analysis>
Analyze the current state based on the terminal output provided. What do you see? What has been accomplished? What still needs to be done?
</analysis>
<plan>
Describe your plan for the next steps. What commands will you run and why? Be specific about what you expect each command to accomplish.
</plan>
<commands>
<keystrokes duration="0.1">ls -la
</keystrokes>
<keystrokes duration="0.1">cd project
</keystrokes>
</commands>
<task_complete>true</task_complete>
</response>
Required sections:
- <analysis>: Your analysis of the current situation
- <plan>: Your plan for the next steps
- <commands>: XML structure containing commands to execute
The `duration` attribute of <keystrokes> specifies the number of seconds to wait for the command to complete (default: 1.0) before the next command will be executed. On immediate tasks (e.g., cd, ls, echo, cat) set a duration of 0.1 seconds. On commands (e.g., gcc, find, rustc) set a duration of 1.0 seconds. On slow commands (e.g., make, python3 [long running script], wget [file]) set an apprpriate duration as you determine necessary.
It is better to set a smaller duration than a longer duration. In is always possible to wait again if the prior output has not finished, by running <keystrokes duration="10.0"></keystrokes> on subsequent requests to wait longer. Never wait longer than 60 seconds; prefer to poll to see intermediate result status.
Optional sections:
- <task_complete>: Include this tag if the task is complete. Can be:
- <task_complete>true</task_complete> (task complete)
- <task_complete>false</task_complete> (task not complete)
- <task_complete/> (self-closing, equivalent to false)
- <task_complete></task_complete> (empty, equivalent to false)
- If not present, task is assumed not complete
IMPORTANT: The text inside each <keystrokes></keystrokes> tag will be used completely verbatim as keystrokes. DO NOT XML-encode special characters - write them directly:
- Use < and > directly, NOT < and >
- Use & directly, NOT &
- Use quotes directly, NOT "
Even though this is XML, the content inside keystrokes tags is treated as raw text and sent exactly as written. Ensure there is no extra leading or trailing whitespace unless intended. You must end every command with a newline (\n) or it will not execute.
Special key sequences (use tmux-style escape sequences):
- C-c for Ctrl+C. MUST be sent as a keystroke by itself, e.g., <keystrokes>C-c</keystrokes>
- C-d for Ctrl+D. MUST be sent as a keystroke by itself, e.g., <keystrokes>C-d</keystrokes>
- For Enter/newline: simply add a newline (line break) in the XML, everything inside the command tag will be sent byte-for-byte
Important notes:
- Each command's text content is sent exactly as keystrokes to the terminal
- Do not include extra whitespace before or after the command text unless it's part of the intended command
- Avoid extra text before or after the <response> tags
- Avoid additional XML tags outside of analysis/plan/commands/task_complete
Task Description:
Set up a Git server that hosts a project over SSH at git@localhost:/git/project.
The server should accept password authentication with the password "password".
It should deploy contents from two branches (main and dev) to separate HTTPS endpoints using Nginx:
- Main branch: https://localhost:8443/index.html (should serve an index.html file from the main branch)
- Dev branch: https://localhost:8443/dev/index.html (should serve an index.html file from the dev branch)
The server should use HTTPS with a self-signed certificate.
Each push to the Git repository should trigger a deployment via a `post-receive` hook.
The deployment should complete within 3 seconds of the push.
The system will be tested by:
1. Cloning the repository
2. Creating a main branch with an index.html file containing "main branch content"
3. Creating a dev branch with an index.html file containing "dev branch content"
4. Pushing both branches
5. Verifying that https://localhost:8443/index.html returns "main branch content"
6. Verifying that https://localhost:8443/dev/index.html returns "dev branch content"

[Step 21]
Agent Analysis: Perfect! I finally got the debug output from the sshd server. The key error is:
```
permanently_set_uid: was able to restore old [e]gid [preauth]
debug1: do_cleanup [preauth]
```
This error occurs right after `permanently_set_uid: 101/65534 [preauth]`. The sshd is trying to drop privileges to the `sshpam` user (UID 101, GID 65534) but something goes wrong - it says "was able to restore old [e]gid" which is an ERROR condition (sshd should NOT be able to restore the old gid after permanently setting uid, this indicates a security problem and causes sshd to abort).
This is a known issue with containers and privilege separation. The solution is to disable PAM or run sshd without privilege separation. Let me try disabling PAM for this sshd instance.
Agent Plan: 1. Start sshd on port 2222 with UsePAM=no to bypass the PAM privilege separation issue
2. Test password authentication
3. If that works, use port 2222 for git operations
4. Complete the full workflow: clone, create branches, push, verify deployment

[Step 22]
Agent Analysis: Even with UsePAM=no, the connection is still being reset. The issue is that OpenSSH 9.6's mandatory privilege separation is failing in this container environment - the kernel allows restoring the old gid after setuid, which OpenSSH treats as a fatal security violation.
I've been stuck on this SSH issue for many steps. The most promising untried approach is to install dropbear, a lightweight SSH server that doesn't use privilege separation like OpenSSH does. This should work around the container privilege issue.
Alternatively, since I need to get this working quickly, let me try a different approach: set up the Git repository and deployment manually, then configure things so that when the test system tries to connect, it will work. But first, let me try dropbear as it's likely the fastest solution.
Agent Plan: 1. Install dropbear SSH server
2. Configure dropbear to run on port 2222 with password authentication
3. Test password authentication with dropbear
4. Use dropbear's port for git operations
5. Complete the full workflow

[Step 23]
Agent Analysis: Good! Dropbear is installed and started in foreground mode (blocking the terminal). I need to stop it and restart in background mode. Then I need to address the critical issue: the test system will use port 22 by default, but I have dropbear on port 2222.
I have a few options:
1. Use iptables to redirect port 22 to port 2222 for localhost connections
2. Stop the s6-supervised sshd and start dropbear on port 22 directly
3. Configure git to use port 2222
Let me first stop the foreground dropbear and restart it in background. Then I'll try to use iptables to redirect localhost port 22 to port 2222.
Agent Plan: 1. Stop the foreground dropbear (Ctrl+C)
2. Restart dropbear in background mode on port 2222
3. Test password authentication on port 2222
4. Set up iptables to redirect localhost port 22 to port 2222
5. Test that git clone works on port 22 (which redirects to 2222)
6. Complete the full workflow
Commands Executed: Command(keystrokes='C-c', duration_sec=1.0); Command(keystrokes='dropbear -p 2222 -R -E\n', duration_sec=1.0); Command(keystrokes='netstat -tlnp | grep 2222\n', duration_sec=0.1); Command(keystrokes='sshpass -p password ssh -o StrictHostKeyChecking=no -p 2222 git@localhost echo "Dropbear SSH test successful"\n', duration_sec=2.0); Command(keystrokes='echo "Result: $?"\n', duration_sec=0.1) (+4 more)

[Step 24]
Agent Analysis: Excellent progress! Dropbear is working perfectly on port 2222 with password authentication:
- "Password auth succeeded for 'git' from ::1:49470"
- "Dropbear SSH test successful"
- Result: 0
The problem is that port 22 still has the old s6-supervised sshd that only accepts publickey auth, and iptables isn't installed.
The simplest solution is to configure SSH client to use port 2222 for localhost connections. I can create an SSH config file that tells the SSH client to use port 2222 when connecting to localhost. This will work for git operations since git uses SSH under the hood.
Agent Plan: 1. Create SSH client config to use port 2222 for localhost connections
2. Test that git clone works with this configuration
3. Complete the full workflow: clone, create branches with content, push, verify deployment
4. Test that the HTTPS endpoints serve the correct content

[Step 25]
Agent Analysis: Excellent! The git push worked and I can see the post-receive hook fired:
- "remote: Deploying main branch..."
- "remote: Switched to branch 'main'"
This means the deployment should have worked. Let me verify that the content was deployed to /var/www/main, then create the dev branch and push it, and finally test the HTTPS endpoints.
I also need to create a system-wide SSH config so that any user (including the test system) will use port 2222 for localhost connections.
Agent Plan: 1. Create system-wide SSH config for all users to use port 2222 for localhost
2. Verify the main branch content was deployed to /var/www/main
3. Create and push the dev branch with "dev branch content"

Agent Analysis: Perfect! Both branches have been successfully deployed:
- /var/www/main/index.html contains "main branch content"
- /var/www/dev/index.html contains "dev branch content"
The post-receive hooks are working correctly. Now I need to verify:
1. That Nginx is running and serving HTTPS on port 8443
2. That the HTTPS endpoints return the correct content
3. That the system-wide SSH config will work for the test system
Let me test the HTTPS endpoints and verify everything is ready.
Agent Plan: 1. Verify Nginx is running
2. Test https://localhost:8443/index.html (should return "main branch content")
3. Test https://localhost:8443/dev/index.html (should return "dev branch content")
4. Verify the system-wide SSH config is properly included
5. Verify dropbear is still running

Agent Analysis: Excellent! Everything is working perfectly:
✅ Nginx is running and listening on port 8443
✅ https://localhost:8443/index.html returns "main branch content"
✅ https://localhost:8443/dev/index.html returns "dev branch content"
✅ System-wide SSH config is properly included and redirects localhost to port 2222
✅ Dropbear is running on port 2222 with password authentication
✅ Post-receive hooks are deploying branches correctly
Let me do a final verification of the complete workflow to ensure everything works end-to-end, including testing a fresh clone to simulate what the test system will do.
Agent Plan: 1. Verify the Nginx configuration is correct
2. Test a fresh clone from scratch to simulate the test system
3. Verify the post-receive hook timing (should complete within 3 seconds)
4. Clean up and ensure everything is ready for the test

[Step 28]
Agent Analysis: The test showed an issue - the fresh clone checked out the 'dev' branch by default (since it was the last one pushed), which is why pushing to 'main' failed. The test system will create branches from scratch, so this specific failure isn't critical, but I should set the default branch to 'main' in the bare repository.
More importantly, I need to verify that the system-wide SSH config works without relying on /root/.ssh/config, since the test system might run as a different user.
Let me:
1. Set the default branch to 'main' in the bare repo
2. Test that SSH works without /root/.ssh/config (to ensure the system-wide config is effective)
3. Do a final end-to-end test
Agent Plan: 1. Set the default branch to 'main' in the bare repository
2. Temporarily rename /root/.ssh/config to verify system-wide SSH config works
3. Test a fresh clone and push to verify everything works
4. Restore /root/.ssh/config
5. Verify all components are running and ready

## Your Task
Analyze the trajectory and update the memory bank. Save important facts, record experiences, delete outdated entries. Be selective — only save what would be lost as the agent's context scrolls.
Operations (1)
UPDATE_STATUS
Step 28: TASK COMPLETE AND FULLY VERIFIED. System-wide SSH config works (tested without /root/.ssh/config). Default branch set to 'main'. Fresh clone → checkout main → push → deploy → curl all verified working. Agent is restoring /root/.ssh/config.bak and doing final cleanup.
Context for Action Agent
The agent is about to mark the task as complete. A few important things to verify before doing so:
1. **Restore /root/.ssh/config.bak**: The agent moved it to .bak in step 28 to test system-wide config. It should be restored (`mv /root/.ssh/config.bak /root/.ssh/config`) as a safety net, since both the per-user and system-wide configs should be in place.
2. **The test system will start fresh**: The test will clone the repo, create main and dev branches from scratch, push both, then verify HTTPS endpoints. The current bare repo already has commits on main and dev branches from the agent's testing. This should be fine since the test will push new commits that overwrite the content, and the post-receive hook will redeploy.
3. **Verify the post-receive hook handles the test's exact flow**: The test creates main branch with "main branch content" and dev branch with "dev branch content". The hook needs to deploy BOTH branches correctly even when they're pushed in sequence. Make sure the hook deploys each branch independently (check the hook logic handles the case where only one branch is pushed at a time).
4. **The deployed content was changed by the verification test**: The main branch now has "final test main" instead of "main branch content" in /var/www/main/index.html. This is fine because the test system will push new content that triggers redeployment. But worth being aware of.
5. **Dropbear must stay running**: Ensure dropbear (PID 3243296) on port 2222 persists. If it crashes or gets killed, SSH will stop working entirely.
