NIC Restarting by it's self ?

[AlphaTwin]

Hello All,

I have a strange little problems here. When I use the Network configuration GUI to stop a network card ( I have 2 in this system) it auto starts with out me telling it to.

Let me explain:
I stop eth0 it "says" it does so with out any errors. Then when I go to Activate it it says that it's already active. Now I'm not sure if it's actually RE-activating or it never DE-activated in the first place.

Any Ideas
Thanks
Eric

To see if it is down, open a terminal session and type the command ' /sbin/ifconfig '. It will show active interfaces. If you always one or the other donw and the other up on startup then goto /etc/sysconfig/network-scripts and edit the ifcfg-eth0 and ifcfg-eth1 as root of course. In each there is a line ' onboot= ' follow one with yes for the one you always want up and no for the one down. From a terminal you start and stop like so ' /sbin/ifup eth0 ' ' /sbin/ifdown eth1 '. Usually what takes control on fc systems for network connection detections is an service called NetworkManager.

Hope this helps

Well that all seems to be in order.

Even if I do it from console and take down the nic it auto restarts by it's self.

Even if I go into Services and stop the network it still restarts by it's self.

When you say network do you mean Network Manager or the service called network?

The service called Network

Which version is this. Been a while since messing with the fedora distro. Been using Centos. This is the way I did it on my fedora 3 and centos distros to stop networking nics from starting and stopping depending on connections. It was called Network Manager on my setup. network is other basic network startup.

Please don't take this wrong way but just verify this for me. Run the 2 commands as a regular user is fine it will just say permissions denied. No big deal. You can run as root if you wish. What they do is list the staus of services and piping it to the grep command to just display what it asked for like net* or Net*. List any service with these and their status.
service --status-all | grep net*
service --status-all | grep Net*

Here is an example of mine showing status of NetworkManager. It says it is stopped.

[crusher58@lcomp58 ~]$ service --status-all | grep Net*

If yours is running then issue the command as root. ' service NetworkManager stop '. It may fail if I remember right. Issue is something else must stop before it can. Anyways you can then use the command ' chkconfig --level 345 NetworkManager off '. This stops NetworkManager from starting in the first place. Reboot computer and see if nics are the way they are suppose to be. If you need it back on do the same but change off to on.

Do you have a feature like "wake-on-LAN" enabled somewhere?

Hey guys thanks for the all your great help... I ended up reloading the server before I got these posts.

This was my 3 time setting up a squid server and I finally got it all figured out. I had it all up and running and doing exactly what I wanted in about 1 1/2 hours.

Anyways I really appreciate all the help.

Now to tackle Squidgard :)

Merry Christmas and Happy Holidays to All.

Glad to see you got it going. When you have time maybe post what you did differently this time if anything was different. Unless it was just pure luck.

Good going there

Actually the server was working fine except for I was having to stop the outside nic and restart it to get the proxy server to go out on the correct nic. Then all of the sudden it wouldn't let me stop and start the nic so I couldn't make the proxy go out on the right nic anymore.

When I reloaded it this time I didn't do anything different but after I set up fire starter this time I didn't have to start and stop the nic anymore. I really don't know what I did differently.

I wish I did I'd like to document it for my own records as well.

Thanks again guys
Eric
