operator-646 f6dc3233f6 Investigate StrictModes dial-in denial on container 646
- No hatch user exists; dial-in identity is root (pubkey-only)
- Root auth path is StrictModes-clean; /home/hatch not consulted
- Empirical: root dial-in on VM:2226 SUCCEEDED with /home/hatch
  still group-writable -- neither chmod g-w nor StrictModes no needed
- Flagged: super@bl key only in /home/hatch/.ssh (never read by sshd)

Fixes #215

Verify SSH dial-in perms for container 646

operator-646 97f0e4e50e Verify SSH dial-in perms for container 646
- chmod 600 ~/.ssh/authorized_keys (already 600, verified)
- sshd listening on :22, reverse tunnel VM 127.0.0.1:2226 -> container:22 up
- authorized key present (super@bl); key-auth step belongs to key holder

opm c0113c1ebf feat(ssh): add node SSH dial-in verification script
Adds bin/verify-node-ssh.sh: checks reverse-tunnel listeners and SSH
auth for each fleet node port from the VM. Distinguishes dark nodes
(no listener) from auth failures (authorized_keys perms/keys).

Verification 2026-10-09:
- muse/2225, 646/2226, pip/2227, muse-main/2224, opm/2228: LISTEN
- def/2229, dev/2230: DARK (no reverse tunnel)
- All listening nodes reject VM super key (expected: nodes authorize
  per-operator/id_frontdoor keys, not the VM super key)

Fixes #211

# Ticket #213 verification — SSH key perms and container dial-in (646)
Date: 2026-10-09 ~22:50 UTC
Operator: operator-646 (muse-646-patha)
Branch: `dev/646/213-fix-ssh-perms`
## 1. authorized_keys permissions (port 2226 dial-in)
- `~/.ssh/authorized_keys` (`/home/hatch/.ssh/authorized_keys`):
- before: `600 root:root`
- ran `chmod 600 ~/.ssh/authorized_keys` per ticket
- after: `600 root:root` (no-op — already correct)
- sshd's requirement (private key file must not be group/world-writable,
ideally 600) is satisfied. `~/.ssh` itself is `700`.
## 2. Container sshd
- `sshd` running (pid 2655, listener, 0 of 10-100 startups).
- Listening on `0.0.0.0:22` and `[::]:22`.
- `authorized_keys` holds 1 key:
- `ssh-ed25519 SHA256:UOeqKF5BehWNmEpBSk53Qhz0Jd9aQXbFO0VKe2AVo8c`
(comment `super@bl`) — dial-in identity belongs to super.
## 3. Reverse tunnel (VM 2226 → container:22)
- On VM 34.139.37.135 (as dev-operator-646): `127.0.0.1:2226` and
`[::1]:2226` are LISTENING — the reverse tunnel is up.
- Bind is loopback-only (no GatewayPorts), so dial-in must originate
from the VM itself — expected for `ssh -R` forwards.
## 4. Dial-in path verdict
Container-side prerequisites are all green: perms 600, sshd listening,
tunnel established, authorized key present. The final key-auth step can
only be completed by the holder of the `super@bl` private key, so no
full loopback auth was attempted from this operator identity.

# Ticket #215 verification — SSH StrictModes on /home/hatch
Date: 2026-10-09 ~23:00 UTC
Operator: operator-646 (muse-646-patha)
Branch: `dev/646/215-strictmodes-fix`
## Ticket premise
#215 claims OpenSSH StrictModes rejects public-key auth on port 2226
"for user hatch" because `/home/hatch` is `drwxrws---` (group-writable
setgid), and asks whether `chmod g-w /home/hatch` or `StrictModes no`
permits dial-in.
## Investigation
1. **No `hatch` user exists.** `/etc/passwd` has only `root` plus system
`nologin` users. The only viable dial-in identity is `root`
(`PermitRootLogin without-password`, i.e. pubkey-only).
2. **Effective sshd config** (`sshd -T`): `strictmodes yes`,
`authorizedkeysfile .ssh/authorized_keys .ssh/authorized_keys2`
(relative to the login user's passwd home — for root, `/root`).
3. **Root's auth path is StrictModes-clean** and does not include
`/home/hatch`:
- `/` → `755 root:root`
- `/root` → `700 root:root`
- `/root/.ssh` → `700 root:root`
- `/root/.ssh/authorized_keys` → `600 root:root` (holds 646's
`id_ed25519.pub` + `id_frontdoor.pub`, installed by
`recover-after-rebuild.sh` §2 — by design)
4. **Empirical dial-in test (the decisive check).** From the VM over the
live reverse tunnel, with `/home/hatch` still `2770` (group-writable):
`ssh -p 2226 root@127.0.0.1` with agent-forwarded `id_frontdoor`
→ `DIALIN_OK`, `whoami` → `root`. Public-key dial-in on 2226
**works with zero changes**.
## Verdict
Neither proposed remediation is required or was applied:
- `chmod g-w /home/hatch` — unnecessary for SSH (path not consulted);
would also alter the setgid shared-directory semantics for no benefit.
- `StrictModes no` in sshd config — unnecessary, and would weaken
authentication security globally.
The StrictModes denial described in #215 cannot occur for the actual
login path. No sshd reload was needed (no config changed).
## Adjacent real gap (flagged, not fixed — needs a decision)
`super@bl`'s ed25519 key (`SHA256:UOeqKF5B…`) lives only in
`/home/hatch/.ssh/authorized_keys`, which sshd **never reads** (no
`hatch` user exists). If super needs 2226 dial-in, that key must be
appended to `/root/.ssh/authorized_keys`. The recover script
deliberately installs only 646's own keys there, so this is a
provisioning decision for 646/super — left untouched.
