ssh(putty) session particularity

Often I develop and control process using ssh(putty) session. Connection with server allow me monitor and do related sub-task like svn/cvs updates.

I don't like when my session give timeout message - server require activity. I use "top" on my local server, but some third party environment don't allow me this (have not access to top!), so I just thinking about this situation after couple minutes of googling discover 'watch' command.

It is so easy:

watch ls

and you session keep alive
