Configuring For Internet Access

[Gerard Seibert]

I am having a problem getting my system properly configured. I have three 
computers - 2 are WinXP Pro and one Free BSD. They are connected via a hub 
and then to a Net Gear RT311 Gateway Router. This is then connected to a 
cable modem. If I run my system with it configured as the files listed below 
show, then it seems to works alright. However, that is not the way the router 
manual says to do it.

The manual wants th OS to obtain an IP automatically.
The IP address of the PC is between 192.168.0.2 and 192.168.0.31
The subnet mask is 255.255.255.0
The default gateway is 192.168.0.1

If I disable the lines in the dhclient.conf file and reboot, my system will no 
longer make an Internet connection. Running nslookup will fail as well.

Neither of my two WinXP boxes exhibits this phenomena. Perhaps someone can 
assist me with this . Also, when I access my router, it does not show a host 
name, although it does for the other two computers, It lists the IP as 
192.168.0.4 as well as it's MAC address.  Why is it not displaying a host 
name? It should, shouldn't it.


Thanks
