[PSR] SSH connection "reset by peer"

[wolledav at fel.cvut.cz]

Hello,

I am no longer able to remotely connect via SSH.

After entering the command "ssh -X wolledav at postel.felk.cvut.cz" I  
immediately get an error "ssh_exchange_identification: read:  
Connection reset by peer".

Thank you for any help,

David Woller
