PuttyCS...You rock

Have you ever wished that there was a way to open many putty sessions, and be able to send the same command to all of the putty sessions at once? I have, and looks like I am not the only one.

PuttyCS is a tool that you can use to send the same command to many different telnet / ssh clients. This little tool has come in handy many times recently.

I had a situation where I had to simulate 200 instances of a command line application running on a server, in order to determine the performance of the application and the load that it would put on the server. Using this tool, I was able to open 200 putty sessions, start the application, and exercise it.

Another situation that I have is ongoing. Working within a cluster environment provides many benefits, but also, it can be a headache. In my circumstance, I have to tail the logs on each node from time to time. Using this tool, it becomes very easy to connect to different servers, and tail the logs on each node.

Once again, I highly recommend this tool, it is sure to save a lot of time and effort.
