Some things like ssh will set an environment variable, but since the user's free to muck with that before running your program it's not trustworthy. Slightly more reliable would be reading the remote host from /etc/utmp, but that's going to be somewhat platform dependent (see Sys::Utmp or User::Utmp) and if someone can manipulate the DNS server you're using it's likewise untrustworthy.

A better solution would be to mandate seperate system logins for each user and use those to determine who's running your program. If someone can circumvent that they more than likely could alter your log anyhow.
