As an educated guess, I'd say that <something> in your network is
killing TCP connections that it has determined to be idle.

So, try this.

Add this to your /etc/ssh/sshd_config

    KeepAlive yes
    ClientAliveInterval 60

Or else add this to your $HOME/.ssh/config

    ServerAliveInterval 60

Why does this work with putty and SecureCRT?  Because, in my
experience, these applications are configured to send keepalives by
default.  The ssh client on your Linux boxen is not configured (by
default) this way.

Hope this helps,
