ifup eth0 required after reboot


Fresh install of Fedora 10 and everything was working fine...

I was having issues with setting a static IP address. I tried both in the GUI and command line. Shortly there after, "NetworkManager" became angry and would allow me to set any ip address. To fix this i had to uninstall NetworkManager.

I then went in and configured eth0 for a static IP address and everything was good again. Until I rebooted. After I rebooted, I didn't have a network connection. ifconfig showed that no eth0 was up. I did an ifup eth0 and everything works great again. I added the line ONBOOT=yes to /etc/sysconfig/network-script/ifcfg-eth0 and rebooted. Still eth0 not showing (w/ ifconfig) but works just fine after I manually do a ifup eth0

This PC is in the back room and is to say the least a PITA to get to the desktop. Below is my ifcfg-eth0 file. What am i missing here?

I haven't used any RH software since the before they split RHEL/Fedora so I am a little out of date on this. But I did wonder whether you want PEERDNS=yes. I also have no idea what the SEARCH= line does.

The first thing I suggest is looking through whatever log file shows boot messages and see if you spot any errors related to this. Another, admittedly somewhat desperate move, would be to (temporarily) modify the ifup script (assuming it is still a script rather than a binary, and assuming that script is where the interface is actually brought up) such that it logs everything it is doing, and then after boot examine the log to see if you can figure out what is going on. If you do this make sure to backup the original version of the script before modifying. If ifup is a bash script you can accomplish what I suggested by adding the following two lines toward the top of the script.

Code:
exec 2> /tmp/ifup.log
set -x
Of course, you can change the file name /tmp/ifup.log to anything you want.
