Hi everyone.  We are using a shop floor application to record the movement of parts and assemblies throughout the plant as operation sequences are performed by the workers.  It's a custom telnet server that receives connections via computers on the shop floor.  Its not perfectly stable, but its usually at night when it fails.  I'm the IT Manager and the entire IT Department, and it's part of my job to get it running again when it has failed, and sometimes that means a call at 6am from a shop supervisor telling me "MAXDC is down again."
I need a way to monitor TCP port 23 on that server, but I haven't figured out how, especially with Spiceworks.  Can someone please point me in the right direction?  I don't want to spend money on this, considering it's just a single server/port I need to monitor like this.  Anyone?
