Description Edward Houston 2005-10-28 15:16:20 UTC

I have no problem with the network for an entire day and then the next morning I log in and I have no internet access.  When I run ifconfig it appears that there is no ipv4 address associated with eth0 (although it appears ipv6 is ok although I don't really know how to test it).  The only solution I have found is to shutdown and reboot.  This problem happens if I us my router to assign a dynamic address via DHCP or I assign a static address from the computer itself.  Is there any solution for this?

Please provide logs ('grep dhc /var/log/messages'), and the contents of
the file /var/lib/dhcpcd/dhcpcd-eth0.info!

Comment 3 Peter Poeml 2005-11-04 10:40:47 UTC

There are a lot of DHCP_NAKs in the log. Can you set DHCLIENT_DEBUG=yes
in /etc/sysconfig/network/dhcp please?

And, could you please run
tcpdump -i eth0 -s 1500 -w ~/tcpdump.out port bootps
maybe for 20 minutes, and provide the ~/tcpdump.out file? Thanks.

Comment 4 Edward Houston 2005-11-15 14:33:05 UTC

I set DHCLIENT_DEBUG="yes" and ran tcpdump for 20 minutes but it only recieved one packet.  I'll attach the file anyway.  By the way I was checking email and surfing the web while it was running if that helps.

Here is the tcpdump file.

another tcpdump (from 10.1)

I did run into this too, for me it looks like an
arp query results in changed ip...

12:31:21.059084 arp who-has 169.254.3.97 (00:50:22:9b:02:97) tell 169.254.3.97

Since it works for awhile after restart of network I tried to remove as much as possible after the initial DHCP check.

A rebote fixed the issue, clue below?

Comment 7 Peter Poeml 2006-01-25 16:01:52 UTC

The link is about Windows -- I don't see any relation.
Unfortunately, there aren't any dhcp messages in the tcpdump files.

When the IP is disappeared, what is the ifconfig output?

Is dhcpcd running then? (Check with 'ps aux | grep dhc')

Comment 8 Peter Poeml 2006-05-08 14:41:30 UTC

Sorry, without further information, I can't do much... I'm closing the
bug. Feel free to reopen with the requested information. Thanks.
