Description Christopher Tyler 2005-10-24 15:44:10 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050927 Fedora/1.0.7-2.1.fc4.nr Firefox/1.0.7

Description of problem:
As soon as NetworkManager is started, it wipes out the routing tables.  The resolv.conf file is fine still shows my normal route.  It activates all interfaces present on the machine and continually 'searches' for a wireless network.  Even after turning off the wireless option from the applet it will not work.  It does recognize that there is a connection but will not set up the route for the interface.  Have not yet tried it with a wireless AP to see if problem is there as well.

Version-Release number of selected component (if applicable):
0.5.0 from Updates-Testing Repo

How reproducible:
Always

Steps to Reproduce:
1. sudo service NetworkManager start
2. NetworkManagerInfo

  

Actual Results:  No wired eth traffic goes in or out.

Expected Results:  It should have recognized the ethernet was plugged in and used it properly without wiping out the routing table.

When the cable is plugged in, what does:

cat /sys/class/net/<your eth device>/carrier

say?  (it will be either '0' or '1')

Comment 2 Christopher Tyler 2005-10-24 16:35:22 UTC

$ cat /sys/class/net/eth0/carrier
0
cat /sys/class/net/eth1/carrier
1
cat /sys/class/net/eth2/carrier
1

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Thanks.

Likely fixed by netlink-based link detection in F6 and later.
