Description Iosif Fettich 2003-11-12 21:22:43 UTC

Description of problem:

When the network init script started, it uses
/etc/sysconfig/network-scripts/network-functions
and specifically check_link_down () to detect live Ethernet cards.

check_link_down relies on mii-tool || ethtool to report about the
status of the card.

As _both_ tests show that the link is down (despite the fact that the
link is actually OK), the card is not activated during a normal
'service network [re]start' or 'ifup eth1'.

But: actually ignoring the result of these tests lets things work like
a charm. The card is fine, the network is fine, the settings are fine,
only the tests seem to be NOT ok.

Version-Release number of selected component (if applicable):
/lib/modules/2.4.22-1.2115.nptl/kernel/drivers/net/fealnx.o

How reproducible:
perfectly

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:


Additional info:
I see this problem on a PC with two Ethernet cards; eth1 is the 'bad one'.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
