	OK, I intend to disable some of these services, but how do I do that?

	Great!, I thought I had to recompile the programs to use shadow 
password. 

	One other thing..whenever I boot up Linux (before I had installed a 
network card), one of the messages that scroll down the screen says:

	sysquery: sendto 198.41.0.4

This turned out to be one of the root servers: a.root-servers.net
Does it have to do this?

Thanks.
