If you are on a T1 or thereabouts, don't sweat it - RH works just fine right out of the box. Otherwise, take a look at http://www.psc.edu/networking/perf_tune.html#Linux, http://cvsview.tldp.org/index.cgi/LDP/guide/docbook/Tuning-Linux/network.sgml, http://www.networkcomputing.com/1122/1122ws2.html, and search Google for tuning linux network. -- Regards, Thomas Cameron
