upgraded from fisher to wolverine. Reboot resulted in the following error during boot:
Feb 24 12:34:03 cr598116-a sysctl: net.ipv4.ip_forward = 1
Feb 24 12:34:03 cr598116-a sysctl: net.ipv4.conf.all.rp_filter = 1
Feb 24 12:34:03 cr598116-a sysctl: kernel.sysrq = 0
Feb 24 12:34:03 cr598116-a sysctl: error: 'net.ipv4.ip_always_defrag'
is an unknown key
Commented out that line from /etc/sysctl and rebooted, however network access is still down
(network access still works on same machine when booted into windows).
That error is not the source of your network problem.
What symptoms are you seeing, what sort of hardware do you have, and
what does your /etc/modules.conf look like?
Putting in NEEDINFO state...

Two network cards, both Netgear 10/100 PCI cards, both have been in the computer and used for 18 months with no trouble
and with various versions of Red Hat.
eth0 is connected to another computer, eth1 is connected to a cable modem. All network settings are configured statically
and IP, netmask, gateway, and dns settings are all identical to the settings under windows.
attempts to ping a valid IP address elsewhere on the net result in ping giving "destination host unreachable"
I can ping both 127.0.0.1 and the IP address assigned to eth1. ifconfig lists eth0, eth1, and lo
On boot, sendmail waits to timeout before the boot up can continue.
Sounds like a kernel problem, most likely.
If ifconfig shows your MAC address as 00:00:00:00... then this is a known and
fixed issue. The fix will then be in our next kernel build. Please confirm
the "all 0" MAC address.
Mac address is all 0's
That is a known and now fixed problem. Will be fixed in the next kernel build.
I will close this as "resolved in rawhide", could you please reopen if a kernel
RMM of version 2.4.1-0.1.14 or later does not fix it (once one becomes
That version is available in rawhide now
I can find the src rpms, but there are no i386 binaries in ftp://ftp.redhat.com/pub/rawhide/i386/RedHat/RPMS/
upgraded to 2.4.1-0.1.14, networking is back. Thanks.
