Can't seem to SSH from Mint into Server 2008

m1ckrz · 09-14-2014, 02:08 AM

Trying to SSH into Win Server 2008 from Linux Mint. Running FreeSSHD (SSH required, password disabled) on port 2222.

I have public key in FreeSSHD\keys
Private key in %HOME%\user\.ssh

When I try to SSH from terminal, key passphrase is accepted but then it requests "user password". Windows user password returns "Permission denied".

As far as I can tell everything is configured correctly. I can only assume it is a permissions issue, but my user is a domain admin and I have allowed necessary ports, firewall rules, etc.

Any help will be greatly appreciated. Thanks!

You can run ssh with the "-v" option (for verbose). You can use "v" up to 2 times (e.g. "ssh -vvv user@host") to get increasingly more verbose debug information. I'm not sure how much it will help, though. This looks like an issue on the Windows end and not the Linux side. Is there a way to run FreeSSHD in debug mode? If so, that might provide some useful information about what's going on.

Here's the output from terminal. This is with CYGWINN on Server '08. Same issue. "Permission denied". I have confirmed the correct passwords, both passphrase and Win user:
