man ssh_config / man sshd_config ?

Since the SSH `session' is determined not only by the connection, but
also by the application which is used (mostly the login shell), there
are actually two kinds of timeouts. Either the SSHd should notice, when
the connection to the client is dead, or the application should notice,
when the user is idle (i.e. the user hasn't typed anything for a certain
amount of time).

In the former case, Damian Szube's answer is correct, and the man-pages
for ssh_config and (more likely) sshd_config are the ones you're looking
for. In the latter case, where there is nothing wrong with the
connection, it's the man-page for your shell.

This is how you do it,

echo "TMOUT=300 >> /etc/bashrc

echo "readonly TMOUT" >> /etc/bashrc

echo "export TMOUT" >> /etc/bashrc
