Resetting Static IP

hessond · 03-25-2008, 08:31 AM

Hello and thank you for reading this post.

I am running Fedora 8 with all updates. Fedora is the only OS on this computer.
When I first installed Fedora, I gave it a static IP of 10.1.100.187. Everything worked fine.

My Network Admin recently pulled that address back and gave me 10.1.100.204.
I used Network Manager to make these changes. All appears fine, however, I cannot ping the .204 address. I can, however ping my computer at .187.

/sbin/ifconfig shows:

Code:

eth0      Link encap:Ethernet  HWaddr 00:08:02:40:7E:7D  
          inet addr:10.1.100.187  Bcast:10.1.100.255  Mask:255.255.255.0
          inet6 addr: fe80::208:2ff:fe40:7e7d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:2427476 (2.3 MiB)  TX bytes:2427476 (2.3 MiB)

I've looked at files here:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/networking/devices/ifcfg-eth0
/etc/sysconfig/networking/profiles/default/ifcfg-eth0

and all show the new IP, however, SOMEthing is grabbing the old ip.

How can I delete the .187 address and place the correct static address in its place?

Thank you for your time!
Cheers,
D

Try to run the following as root.

/etc/init.d/network restart

Then run ifconfig to see if it's picked up the changes.

you'd need to restart the network interface to use the new ip address. just edting the text file directly will do nothing in itself.

Based on your ifconfig output your Fedora Box still uses the .187 address.

From the menu:
System > Applications > Network
choose your Ethernet device and in the 'General' tab set your statical IP to the new value.

You HAVE to restart networking after that to make the settings apply, or simply do a reboot (restarting networking is faster, however).

Hope this helps,

Thank you all for your replies -

SIMP -
Yes, System -> Administration -> Network takes me to Network Manager which is where I reset the new IP originally. Listed here is the new address. Looks like it *should* work....

Jay -
I did restart the Network as you suggested:
/etc/init.d/network restart (Chris, this is what you're talking about, right?)

In fact I restarted the whole box.

Darn! It's doing the same old thing. Still coming up in the old address.

I know I'm missing something. I just don't know where to start. Any ideas from here?

Thanks,
D

i would guess that network manager could be fscking around with things. uninstall it, disable it, it's a sack of rubbish for a fixed machine like yours.

Thank you very much, Chris!

I disabled Network Manager, and all worked just as you said.

Now on to my next challenge....

Cheers,
