pvetui guests exec <id> <commad> ssh authentication fails

[ristomatti]

The newly added guests exec subcommand doesn't seem to find my SSH key. Does this need to be configured somewhere? I'm using the token based authentication.

$ pvetui guests exec 200 "ls /dev"
{"error":"exec failed on LXC 200: failed to connect to 192.168.5.11:22: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain"}
Error: exec failed on LXC 200: failed to connect to 192.168.5.11:22: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

# No issue using ssh directly

Thanks for reporting the issue. It uses the same mechanism as the Command Runner plugin: SSH to host node and use pct exec to run the command inside the container. Are you using SSH agent auth? If so, that's a gap in the current version — pvetui's SSH client only checks the standard key paths (~/.ssh/id_rsa, ~/.ssh/id_ed25519, ~/.ssh/id_ecdsa) and doesn't consult the agent.
I'll need to add support for both SSH agent and custom key paths.

I'm using SSH agent yes, but I have postfixes on my keys in case I need different one for work for instance. pvetui guests exect started working after I symlinked ~/.ssh/id_ed25519 to ~/.ssh/id_ed25519_personal.

Thank you! From my side this can be closed unless you want to use it to track SSH agent support.

Aside: pvetui is awesome. Have you considered adding shell completions? I'm asking since I built (with LLM assistance) ones for zsh yesterday. Let me know if a PR would be welcome.

I would guess that the TUI library you're using supports completion generation... and that you've already planned implementing them later on using said library. 🙂
