Static Ip Networking

tiger3 · 12-06-2003, 09:22 AM

have you tried this?
As root remove the default route with the command:
route del default 10.0.0.254

Did you do this?
Edit your /etc/sysconfig/network-scripts/ifcfg-eth0 and remove the line with the GATEWAY.

Yes, if I delete the default gateway, ping gives the error "Cannot connect" or something similar. Nothing seems to work without a default gateway entry. And I just realized the forum went to page 2.

*edit*

Also, I used the "service network restart" command to load the net values after the config file was edited

Try adding a different default route.

route add -net 10.0.0.0 netmask 255.255.255.0 dev eht0

OR
route add -net 0.0.0.0 netmask 255.255.255.0 dev eht0

I've tried the -net 10.0.0.0 command but I don't think the -net 0.0.0.0 one, I'll try that next time I get a chance to work on it. The computers are in another building and I don't think it is open on the weekend. But thanks for all your help and such, if it doesn't work I'll be posting here again.

Thanks alot

The only other thing I can think of is did you load any kind of firewall that would possibly block ICMP packets? ipchains iptables for example? Also, I see you have a much older version of Red Hat too.
If possible coult you post your ifcfg-eth0 file and rhe results of netstat -r ? I will take a look in the morning.
It is nearly 1 a.m. here and I need my beauty sleep!

Alright. I've already posted the settings from the ifcfg file I used, since I find it easier to edit that instead of using ifcfg. I do not have direct acces to the actual file right now, and I've posted the routing table in the first post.

DEVICE=eth0
BOOTPROTO=static
IPADDR=10.0.0.1
NETMASK=255.255.255.0
GATEWAY= 10.0.0.254 (default)

Uh, no, the lookback address is handled internally, it will still
work even if the NIC is broken.

Can you try swaping the network cards between two computers? Or just get anohter one, they are very cheap.

dook · 12-06-2003, 11:30 AM

Ok zaphodiv. Also when I ping the broadcast addr, I get replies back from only the computer I pinged from. These cards are rather old, but I do not have a budget to get more. There's cards available from other computers that I'll try. At least until I get everything consistent. Is there some online tutorial strictly for static ip networking? Like, a REAL one? www.yolinux.com has a pretty good one but none of that worked.

This is a great reference, but it may be more than you need.
