Beware: F10 network setup bug and workaround

[aleph]

Dear all,

If you are using F10 with static IP, you may have trouble using system-config-network GUI to setup your network. I experienced this bug in F10 Preview and Final: the IP address, network mask and gateway address will not be saved correctly by system-config-network. The network mask value saved in the config file will be the same as the gateway address, which is obviously wrong. The result is network appearing down after restarting the network service.

To workaround this bug, go to /etc/sysconfig/network-scirpts directory. As root, edit the file ifcfg-eth0 (of ifcfg-XXX where XXX is the interface you are configuring) with your favorite editor, change the values of network mask/broadcast manually, save the file and restart network.

I hope this little howto could help you enjoy your newly installed F10. I don't know much about other network configuration ways (eg. NetworkManager) though.

Thanks your workaround works. It seems unfortunate that it comes to this though.

Indeed. My machine always installed without any problems on all versions of Fedora right back as far as FC3. Incredibly I have been arsing around with my new F10 install and I cannot figure out how the hell to get networking working at all. It just does not seem to want to come up. Previously it always just worked. Very disappointing....

Is this for when the router doesn't provide the ability to assign static IPs on an internal network?

I think this is just a GUI issue. Someone borked the mapping from GUI widgets to text fields in the saved file.

I installed FC10 on 29-Nov-2008. Uptill FC9, I used to get the prompt for setting ip, mask and gateway during installation itself, but it wasn't so during the installation of FC10. The GUI network set-up was also slightly different as I got the different window than on FC9. After setting up the ip, mask and gateway and saving it on, the network activated but there was no data transfer, as if the network is dead.

When, checked the ip again, it was found that the mask value assumes whatever the value of gateway; a bug most likely.

As told in this forum, I will try changing the file ifcfg-eth0 with editor.

Thanks.
