I recall preferring rsh to ssh when working on s390 for the very same reason. However, one useful feature of ssh (that did not exist at the time) is that you can use one existing connection. In .ssh/config: Host * ControlMaster = auto ControlPath = ~/.ssh/control/%h__%p__%r__%l This means that the first connection to the system will have the full 15 seconds of handshaking. But the next one will simply connect on top of an existing connection. I suspect it would even be less than the 1 second for the telnet connection. If you have a number of simultanious connections, it may help. Alternatively, start a single "control connection" when you start working, and keep it working for as long as you need it. > Please don't tell me to get faster > computers unless citing a specific liability from > Shorewall.
