Tricky little problem, send signal to other machine without user

Hi everyone! I want to be able to send a signal to another machine on the same network, and have it trigger a script on that machine. Here's the reason why I can't just ssh: I don't have a username on that machine, but there is a user that is always logged on that I can do stuff on.

So, I want to have a script constantly running in the background on that machine, and from mine, essentially ping it, and have it run another script. I'm not really sure how to do this...I know the IP address of the machine I want the script on, so I was looking into using something called netcat (man nc).

Does anyone have any advice or suggestions?

Thanks!

fence_cpint(8)						      System Manager's Manual						    fence_cpint(8)

NAME
fence_cpint - I/O Fencing agent for GFS on s390 and zSeries VM clusters SYNOPSIS
fence_cpint [OPTION]... DESCRIPTION
fence_cpint is an I/O Fencing agent used on a virtual machine running GFS in a s390 or zSeries VM cluster. It uses the cpint package to send a CP LOGOFF command to the specified virtual machine. For fence_cpint to execute correctly, you must have the cpint module installed, and hcp in your PATH. NOTE: for fence_cpint to send a command to another virtual machine, the machine executing it must either be a privi- lege class C user or it must be the secondary user of the virtual machine to be fenced. This means that unless all of you GULM server nodes are privilege class C, fence_cpint can only be used with SLM. fence_cpint accepts options on the command line as well as from stdin. fence_node sends the options through stdin when it execs the agent. fence_cpint can be run by itself with command line options which is useful for testing. Vendor URL: http://www.ibm.com OPTIONS
-h Print out a help message describing available options, then exit. -u userid userid of the virtual machine to fence (required). -q quiet mode, no output. -V Print out a version message, then exit. STDIN PARAMETERS
agent = < param > This option is used by fence_node(8) and is ignored by fence_cpint. userid = < parm > userid of the virtual machine to fence (required). SEE ALSO
