packet sniffer
			 
			 
			
		
		
		
		I like ethereal for packet sniffing... its easy to use, and if you're running linux you've probably already got it installed.  I imagine there is a Win32 build for it too, though I'm not certain. 
 
I havent used a memory editor since I used debug under MS-DOS 3.11. hehe
