i was experiencing a new problem (well, it isn’t really a problem, it’s just annoying) when i opened an ssh connection to my server at OVH and i wasn’t active for let’s say about 10 minutes. when i wanted to enter a new command, the session always closed with the error:
Read from remote host xxx: Connection reset by peer
Connection to xxx closed.
sadly i couldn’t find out what exactly made this behave like this (i believe it has to do with m0n0wall, but the connection timeout there is set to 3600 seconds, so i don’t know why it happens), as it was never a problem until then. but i found an easy workaround that keeps the connection alive:
put this line into you ~/.ssh/config
-
ServerAliveInterval 120
this sends some data through the ssh connection every 120 seconds and avoided the connection from being closed.
aha….thats why our firewall log say’s: An amount of 7GB outgoing traffic from an internal IP to an external IP over Port 22, happened in a very short time;)

hehe no it’s not related, this option for ssh generates only little traffic.
i uploaded something one day, this might be it. where exactly did you find this statistic?
