I'm only partially new to Linux. I'm running Fedora 11. I've just set up two machines, I thought to be identical. Evidently I missed something. I had some problems getting the network started on the second machine, and I must have forgotten a name change somewhere. Anyway, after doing lot's of comparisons between the boxes, editing and renaming and re-linking the ifcfg-GigaStorey file, they are both functioning. The problem is that whenever I start or restart the network on box 2, it reports the following error:

Bringing up interface GigaStorey: RTNETLINK answers: File exists
Error adding address 192.168.1.6 for eth0.
[ OK ]

The file ifcfg-GigaStorey is linked in the following directories
/etc/sysconfig/network-scripts
/etc/sysconfig/networking/devices
/etc/sysconfig/networking/profiles/default

The contents of the file on box 2 (error) are:
# Networking Interface

HWADDR=00:10:C6:A3C:C7
ONBOOT=yes
IPADDR=192.168.1.6

The same file on box #1 (No errors here) is:
# Networking Interface

Like I said, it's not super critical, just annoying. The networking comes up ok, but the error is puzzling. I figure if I learn what this problem is I'll be one step closer to my Linux beanee. As always, the fates will smile on you for your gracious help!

the problem is between 2 services [network],[NetworkManager]

u should use either of these Modes :
a. GUI mode
#chkconfig --level 35 NetworkManager on
#chkconfig --level 0123456 network off

#/sbin/service NetworkManager stop
#/sbin/service network stop

#/sbin/service NetworkManager start

b. CONSOLE mode
#chkconfig --level 35 network on
#chkconfig --level 0123456 NetworkManager off

#/sbin/service NetworkManager stop
#/sbin/service network stop

#/sbin/service network start

Thanks f14f21, this fixed the problem right away. I reviewed the man pages for chkconfig and I think I have a better understanding now. Service priority seems to be obvious (order in which services are brought up or down?) Runlevel is a bit more perplexing, I've reviewed the man pages for shutdown, which is where I expected to find an option to re-boot at a specific runlevel, but nooooo I miss-guessed, but hey, that's what man pages are for. While the man pages make reference to runlevel, there doesn't seem to be an option. I also looked over the man pages for init, telinit, and runlevel. My questions are: What is the "regular" uses of the various priorities and runlevels? and How do I set the runlevel for the next reboot? If you don't have time to write out a lengthly answer, but can refer me to some documentation, I can rtfm.

Thanks

Duuuhhhh, let's all say it together, "I should always check Wikipedia first" - They have a pretty good explanation of runlevel and how/why it works.

Hi,

i am using archlinux and i have the same error and have to manually execute "netcfg wpa_suppl" after boot. how can i fix it, so it starts automatically?

here are the files:

edit: problem solved! removed "network" from daemons.
