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!

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
