Re: [ILUG] somewhat off topic: ping and TCP/IP

"I just read in the WinGate proxy server website that if you can ping
another computer then TCP/IP must be working ok. Is that right? Does
ping only work over TCP/IP???"

pings are ICMP - internet control message protocol. part of IP. TCP runs
on top of IP, so if ICMP packets get through chances are tcp/udp packets
will too.

"Another question: client machines are set to connect to the proxy
server on port 90 (sic), is this wrong? HTTP requests usually go
through port 80, right? If the server and clients are all set to 90 is
this ok? Is it a good idea?"

it's a proxy port, so it doesn't really matter. the most common i've
seen is 8080 (squid default). If you want to run a webserver on the
proxy aswell, eg for a support page, then /don't/ set the proxy to 80.
