lynksys router.... static ip?
 

Hi all. I have a lynksys router connecting my little network to a DSL line. I have been trying to set up static ip addresses within my network, but i can't get it to work. I set up my linux box w/ an ip of 192.168.1.101 , netmask of 255.255.255.0 and gateway of 192.168.1.1 . I don't understand why this is all not working... can somebody help?

is there another computer at 192.168.1.101 ? check this first.

what exactly did you do that didn't work?

from the command line, as root:

ifconfig <network device> 192.168.1.101 netmask 255.255.255.0
route add default gw 192.168.1.1

that *should* do it

if you're using LFS you should know where the scripts are. it might be a problem of networking not being started at bootup, or an error in the ifcfg-eth0 or whatever interface it is.

Thanks for getting back to me. Yes, i am using lfs. The only machine with that ip is my other lfs system (which is on the same computer... uses dhcp). I'm sure it's something simple that i'm not doing. I was wondering if you had to specify the dns servers? if so, how would i do that? here's some of my files:

/etc/sysconfig/network:
HOSTNAME=lfs2
GATEWAY=192.168.1.1
GATEWAY_IF=eth0

/etc/sysconfig/network-devices/ifconfig.eth0:
ONBOOT=yes
IP=192.168.1.101
NETMASK=255.255.255.0
BROADCAST=192.168.1.255

and my bootup script is working fine. Any other suggestions?

ooh yeah... I can connect to the network i.e. ping the router and what not, but i can't get outside, "unknown host"- thats why i'm thinking dns?

You forgot to add your DNS entries to your /etc/resolv.conf file most likely.

ahah

one of two things that haven't been mentioned

either your default route isn't working, which it should. type
netstat -nr

or the linksys router isn't routing IPs it didn't had out, there should be some configuration option somewhere in that linksys regarding that. I could have sworn I saw that before..

I doubt the resolv.conf issue, it could be, if you have ever grabbed a dhcp lease it *should* update the resolv.conf and it will stay that way until you change it. Either way it is a good thing to check

thanks tricky kid. I copied /etc/resolv.conf from my working lfs system, and it works now! (i'm writing this from lynx on my new system). Thanks a lot.

SInce the Linksys cable router hands out 50 dhcp addresses starting at 192.168.1.100, it might be a good idea to use static addresses either below 192.168.1.100 or above 192.168.1.49. This way you insure that you won't get a duplicate address.

A note. On versions of the bios below 1.4.27. the Linksys had a bug that would cause it to duplicate a DHCP address. For anyone using a Linksys, upgrade its bios to 1.4.27 or later. -mk

Thanks Mike, good suggestion.
