Newbie: Now to configure DNS and gateway
 

Hello,
I am running Fedora core 5 on my linux box. Usually it detected my network settings, or I would just run dhclient.
However, something went wrong with my router and it's no longer being picked up automatically as DNS and gateway. On my windows machines, I would usually go into TCP/IP settings and configure:
IP: 192.168.2.20 (IP address of my linux box)
Subnet...
Gateway: 192.168.2.2 (IP of my D-link router)
Default DNS server: 192.168.2.2

On my linux box:
I just run
ifconfig eth0 192.168.2.20
to set the IP, not sure how to set up DNS and Gateway

How do I do this in linux, is there a quick command do set these things: specify the gateway and the Default DNS so the internet works?

Thank you very much for your help in advance!!

Best Regards
MK

Login to your router and make sure the DHCP service is still running. Sounds like you may have accidentally shut it down.

Manual DNS/Gateway configuration.
 

Your DHCP server is probably just disabled, but I have written up terse instructions for you to follow anyway. It's a good thing to know!

Gateway
if you use route to manage your routing tables like I do, seting a default gateway is easy...
route add default gw 192.168.2.2

DNS
dns is really easy. Edit the file /etc/resolv.conf and add the line
nameserver 192.168.2.2

the routing table will need to be configured each time your computer starts. Fedora should provide a utility for setting the default gateway. /etc/resolv.conf is just a regular file, and will persist until changed by you or by automatic configuration via dhcp.


Good luck.
