Thank you very much for tht Amit, that is the type of thing I'm looking for. I appreciate that info.
I got around to trying it but am getting an error, Command "ch/add" is unknown, try "ip route help".
I'm not familiar with these commands so I don't want to experiment for fear of knocking out my server. Anyone know what exactly I should be entering into the command line (other than the exact IP of course)? My fear is that I'll mess up the server.
Also, I don't suppose there is any automated way to do this? (e.g., in PHP/Perl on a per-script basis) Seems like there most likely isn't. (though I wonder if passthru() would work in PHP...)
