What you're proposing would actually be very difficult to implement. The output from tail -f would need to go to a program that would be a homebrew telnet server.

And what is supposed to happen to the output from tail -f if no one has connected to the telnet server? Just discard it?

And when the log file gets too big...then what? Kiill the tail -f and roll the log file? By the time you get tail -f going again, you may have missed some lines. Is that acceptable?

I would think that patrol can do this sort of thing via snmp. Have you looked into that?

If patrol can't handle this, then I would package up the log entries in little files and retrieve them via ftp.

And one thing to not try is syslog. It moves error messages around via UDP and does not care if they get lost.
