i'm trying to log via ssh to a server i was able to login before...
I am on a Mac os and the server is an ubuntu machine. The strange thing is that if i try to login via an SFTP client (like Transmit) i can access to the server even if i cannot send files...
If i try to connect with another client to the server, i can, so it's a problem of my system.
This is my session log
