I have a work computer (Ubuntu) and a personal computer (win11 with Ubuntu WSL, port forwarding enabled). Using Termux in Android, I wrote the public key of my phone to the authorized_keys files in both computers. All devices use NordVpn Meshnet. I have absolutely no problem connecting to both of my computers (WSL and Ubuntu) from my phone using ssh (using IP adresses provided by Meshnet).

However, for some reason, I can't use ssh from home pc to work pc or vice versa. In powershell, I can succesfully enter my passwort, but the terminal freezes after the login. Using the ssh command with -vvv does not give any useful information, as the login is successful. However, when I use the flags --noprofile --norc, I can actually use the terminal. Also, alternatively, deleting the .bashrc file works fine on PS, but not on PuTTY or WSL.

How can I solve this weird problem? What confuses me is the fact everything works fine on Termux...

Edit: output of the ssh -vvv command:

  • Have you tried to check the sshd logs on server side? Commented Jun 13 at 13:20
  • Can you add the full ssh -vvv output to your question anyways? It's helpful to see exactly where your terminal is freezing at. Have you tried setting up key pairs for the other devices as well? Commented Jun 13 at 13:53
  • @Cpt.Whale I have added the -vvv output after I have typed my password :) Commented Jun 14 at 11:35
  • @Robert i can do that the day after tomorrow, until then unfortunately not :( Commented Jun 14 at 11:37

Check the sshd_config file located at $Env:ProgramData\ssh Make sure password authentication is enabled: PasswordAuthentication yes

Create the SSH subsystem that hosts a PowerShell process on the remote computer: Subsystem powershell C:/progra~1/powershell/7/pwsh.exe -sshs

After the change you need to restart the SSHD service:

Restart-Service sshd

Further the 8.3-style name for Program Files should be c:\progra~1, check this with the following command:

Get-CimInstance Win32_Directory -Filter 'Name="C:\\Program Files"' | Select-Object EightDotThreeFileName

Let me know if this works for you.
