How to stress test a telnet server application?

We have a Unix application that is essentially a glorified telnet server.

We have no access to the Unix server, yet we need to do load/stress testing.

We really need to be able to simulate a few hundred user sessions lo开发者_如何转开发gging in and performing certain actions.

I thought I could perhaps use a terminal emulator that performs these actions concurrently.

But I am unsure of the best way to do this.

Is there any software that exists that would allow me to do this? Or could someone recommend as easy way to do this?

If I was going to do something like this I'd use a multithreaded perl program built around Net::Telnet, maybe using Expect and Benchmark depending on your objectives.
