If it's anything like flexlm, there's a license file on the local machine which tells it the host name and port number of the server. Flexlm actually doesn't care which of our various subnets the client is on, only how many licenses it's passed out, though our firewall rules DO care :-) In any case, it would be worth the effort to try to fake it out using ssh. Here's a sample command line for forwarding SMTP (port 25) that I (used to) use for sending mail as if local, to bypass our anti-relaying rules (look at the headers of this message, for the current solution :-) /usr/bin/ssh -q -x -f -N -L 20025:julia.math.ucla.edu:25 julia.math.ucla.edu (-q - quiet, -x = omit X-windows, -f = drop into background, -N = omit shell command, -L = port forwarding.) I test by doing... telnet localhost 20025 To my HELO, it responds: 250 julia.math.ucla.edu Hello julia.math.ucla.edu [128.97.4.254], pleased to meet you The packets appear to come from Julia, the host listed in the -L parameter. It might be a good idea to turn on keepalives, so a forgotten connection automatically exits when the net connection goes down. James F.
