SSH Connection

I have setup a sql forwarding connection to mysql server. However, the connection always hangup after 2hr... The problem can only be solved by resetting the ssh for this connection.

Is there something that I can configure, say TCP or session idle timeout to solve the problem ? Tsk

When you are creating your ssh tunnel use the following option to send a packet every 100 seconds to let the server know you are still active.

ServerAliveInterval=100

Where should it be setup, under /etc/ssh/ssh_config or /etc/ssh/sshd_config ?

What's the difference between these 2 files /

Currenty, I change the file sshd_config

ClientAliveInterval 3600
ClientAliveCountMax 4
TCPKeepAlive yes

Tks

You can set those in sshd_config, but then any ssh connection will never timeout, which is a security risk.  for example:

ClientAliveInterval 30
TCPKeepAlive yes
ClientAliveCountMax 99999

Instead, when you are putting in your command to bring your ssh tunnel up, you can set these variables yourself.
