This has saved my butt many times.

You could substitute tmux if you want, I just don't know the equivalent of screen's <code>-D -RR</code> functionality..

One annoyance is double login for login failures not related to screen.

<pre>
# always use screen on remote hosts if possible
ssh ()
{
    if [ x$1 = x ]
    then
        # ssh doesn't make sense without arguments
        echo "must supply hostname" >%2
    elif [ x"$2" = "x" ]
    then
        # only hostname specified, try to ssh and launch screen
        if ! /usr/bin/ssh -t $1 screen -A -D -RR
        then
            # if attempt to launch screen failed, fall back to regular
            # ssh
            /usr/bin/ssh $@
        fi
    else
        # if user passes more than one arg, it's something to execute
        # on remote host, and thus we don't want to launch remote
        # screen.
        /usr/bin/ssh $@
    fi
}
</pre>
