Just add the following line to /etc/ssh_config (on the machine you’re SSHing from) :

ServerAliveInterval 60

Next time you SSH of SFTP you’ll be sending ‘keepalive’ packets every 60 seconds. No more Connection reset by peer!
If you have root access on the remote server, you can also set

ClientAliveInterval 60

in the same place to achieve the same effect.
