Do you remember if you had updated from the previous version, i.e. from dhclient-4.1.1-26.P1.fc13 or from something even earlier ? dhclient-4.1.1-27.P1.fc13 was only a security update for DHCPv6 server so the dhclient was actually not changed between 4.1.1-26.P1 and 4.1.1-27.P1. I need you to do some investigation. From this page https://koji.fedoraproject.org/koji/packageinfo?packageID=305 you can download every older dhclient build. It would be great if you could discover which version of dhclient is the first "problematic" one. The procedure could be something like: 1) download e.g. dhclient-4.1.1-13.fc13.i686.rpm 2) install it with 'rpm -Uvh --force dhclient-4.1.1-13.fc13.i686.rpm' 3) verify it's working 4) download e.g. dhclient-4.1.1-26.P1.fc13.i686.rpm 5) install it and verify it's not working 6) download some other dhclient version and test if it's working or not Remember you can always install the one that you already verified as working. > On the systems that do not work this is followed by > DHCPNAK from 192.168.2.1 > DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 > send_packet: Network is down This looks like the router sent (from whatever reason) NAK and dhclient correctly moved to INIT state where it tried to send DISCOVER but was unsuccessful because the interface was down. Dhclient sets the interface down to delete routes and clear arp cache. It also sets it back up but this doesn't work (don't ask me why) on some devices (see bug #574568). So I removed the 'setting device down' in dhclient-4.2.0-8.fc14 (F14 only, no F13). So if this is also your problem (not sure with that) then the newer dhclient in F14 should be ok. > The F14 system that is still working has pending updates for dhcp and > some NetworkManager packages. You can also first download (so you can always install it from downloaded rpm) the version that you know is working and then try some newer versions to discover which one (if there's such) breaks. Thanks. I had not tested the previous version because I don't have a wireless I can connect to when I'm at home. Thanks for the pointer to the older versions, I will download some of them and try them. I don't really want to fiddle with the F14 installation since that is the only one that is working right now - if I lose that I lose connectivity until I get back home. So give me a day or two to try some of this. BTW I tried to rpm -e the dhclient package in the i686 F13 machine before installing the older version, and there were just too many dependencies. So I did the rpm -ivh --force and that worked - on that machine. But it hasn't seemed to work on the x86_64 F13 machine, but maybe I didn't do it right and need to try again.

At the moment you are the only one seeing this problem, so it's your itch :-) > BTW I tried to rpm -e the dhclient package in the i686 F13 machine before > installing the older version, and there were just too many dependencies. > So I did the rpm -ivh --force and that worked - on that machine.

I always use 'rpm -Uvh --force dhclient-n-v-r.rpm' So today I tried all the dhclient from koji on the F13 x86_64 system and they all worked, and I let the F14 x86_64 system update completely and it works (dhclient 4.2.0-14P1) So please close the bug, excuse me all to hell for bringing it up, must have been having a bad router day yesterday.

If it occurs again feel free to reopen this bug and attach wireshark (network traffic analyzer) packet dump from the unsuccessful try. |
