(if so, yes!) have you configured it? if not then you probably don't need it, as it does not thing very useful until you tell it to. rinetd would be useful if for example you wnated to run an ftp server inside your firewall, but have people connect to the firewall for ftp service. it would make it look like there was ftp running on the firewall but would just redirect any connections to wherever you told it to (the internal host). if your just using IP NAT to give a bunch of machines net access but are not running any services on the internal machines that need to be accessable to the outside you don't need rinetd. > > how about ypbind? what's that, and why? its for NIS (Network INsecurity ;-) [1]) you would need it if you wanted to say have all your machines authenticate against one, instead of having a different username password on each machine. (thats just one thing NIS can do) problem with NIS is its not all that secure, NIS+ solves much of the security issues but AFAIK there is no implementation for GNU/Linux. [1] the real name is Network Information service iirc. used to be called Yellow Pages but then whoever makes phone books sued over it.
