Can't login to one specific SSH server #886

Closed Jannomag closed 3 years ago

Jannomag commented 3 years ago

Hi, I recently switched to a Raspberry Pi 4 as my homeserver, with installed Raspberry OS Buster. Before this my homeserver ran on an old laptop mainboard and Ubuntu 20.04 Server. Since I switched I can't use FluentTerminal anymore to connect via SSH to my homeserver. This is what happens: Screenshot 2021-01-22 230652

It happens to my homeserver, only. I can connect to a similar build at a friend. Also RPi 4 with Raspberry OS Buster, nothing different.

I enabled the log, which has this in it after I tried to connect:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@    
]0;C:\WINDOWS\system32\OpenSSH\ssh.exe[?25h

I alread reinstalled and reset the application. I have this issue on both, my desktop and laptop, both running Windows 10 x64 20H2 Build 19042.746.

Does it work if you connect manually from powershell? Can you pass -vvv to get some debugging? (ssh -vvv ...)

Jannomag commented 3 years ago

Connection through Putty, Kitty and Powershell works fine, also through ssh using Ubuntu 20.10. Output of Powershell using -vvv:

By default, FT uses Mosh -- it doesn't look like you've got that installed on your RPi, but I'm guessing you were smart enough to uncheck that box.  I can also see that you use password login to access your RPi - I don't personally use password-based login, so I haven't tried that with FT.  Can you try adding your id_*.pub to the RPi's authorized_hosts file, then use the corresponding private key in the "Identity file path" setting?

Jannomag commented 3 years ago

I created the key using powershell command ssh-keygen.exe -t rsa -C "USERNAME". Now I'm getting this in FT:

Load key "C:\\Users\\janno\\.ssh\\id_rsa.pub": invalid format

The connection using powershell works with this key file.

And somehow the ssh connection worked using password ... at least for now.

hanskokx commented 3 years ago

I had something similar happen with my keys recently.  For me, the solution was to remove any line-breaks in the keys.

The identity file path in Fluent should point at the private ssh key, not the public one (change from id_rsa.pub to id_rsa).

hanskokx commented 3 years ago

Good catch. I totally glossed over that part.

Jannomag commented 3 years ago

Selecting the id_rsa instead of id_rsa.pub fixed it for me. I can login with it now. Thanks!
