test if ssh server

[AlbanMinassian]

Hello

I have a new PC and I immediately installed an iroh-ssh server.

$ iroh-ssh server --persist
Connect to this this machine:

  iroh-ssh xxxxxxxx@623f38ca4d396e304d68ec70c790d6bc4704effa39df15f6e374293e32af0799

  (using persistent keys in /home/xxxxxxxx/.ssh)

client -> iroh-ssh -> direct connect -> iroh-ssh -> local ssh :22
Waiting for incoming connections...
Press Ctrl+C to exit

When I connect with a client, I get the following:

Failed to connect to SSH server: Connection refused (os error 111)

Could the iroh-ssh server command check beforehand that the SSH server is running on port 22 (or --ssh-port) before displaying Waiting for incoming connections... ?

I solved the issue by installing openssh, but I would have appreciated iroh-ssh telling me there was no SSH server running.

Kind regards,
Alban Minassian

Hi @AlbanMinassian, thank you for your suggestion.

Since iroh-ssh is fully dependent on a installed SSH client and server this should be checked and if missing the user should be informed. I added your suggestion in this latest PR #44

Does this look good to you? I will merge this tomorrow, if you have any feedback I am happy to make changes.

I merge the changes into main. Feel free to reopen this issue with any suggestions/problems etc

Thanks for improving iroh-ssh for forgetful people like me.
