Ok guys a quick newb question. I have been reading up on the Red Hat Enterprise 4 for dummies book along with installing and playing with the configurations of Cent OS 4. I have yet been able to find any information on how to find out what your IP address is. I have it set to use DHCP from our Windows server and I looked under the network card configuration settings but can not find any command or GUI place that will show your IP Address. When I go to a windows machine and try to ping the Cent box by its name it cant find the host. Now I know I can go into the DHCP server but I need to learn how to find it on the Linux box.

Another question has to deal with Samba. I set up samba using the GUI interface then ran  service smb start command to start up samba. The book says I should be able to browse the network with a windows machine now and find the linux box but I am unable to. Any clues why its not showing up on the network?
