Question summary: i run a halflife 1.5 dedicated server on my PC, and want to sniff the remote console password with my slackware laptop to check out sniffing.
Full story: I have a PC with XP and a laptop with slackware 8.1. I recently set up a half life dedicated server on the linux laptop for my school's LAN, but found that the CPU was NOT powerful enough to host a lag-free game. I switched it over to my desktop, works fine.
People around here seem to hate steam, so i'm running version 1.5, which may mean little to yall cuz you might not waste your time with games, but the point is that the remote console password is transmitted in plain text in hlds version 1.5. This could pose a problem because I know a few linux-savvy people that would delight in taking over the server. But my real motivation in trying to sniff the password is cuz i'm fascinated with the concept, and would like to learn more.
I have no idea where to start. I've googled and checked sourceforge for sniffing programs, but bandwidth constraints here prohibit me from downloading every little thing to check it out - are there any suggestions? I figure what I'd need to do is just check network traffic going in and out of my desktop's IP address - is there a sniffing program that will let me monitor network traffic from an IP other than the IP of the computer I'm sniffing from?
