Keep loosing WAN IP Address - dhclient does not seem to do update

Krakke · Feb 21, 2007, 8:55 PM

@hoba:

Atm there is a workaround in pllace that will restart the dhclient when it exits. Does it get restarted?

Nope at 20:01:24 it exited, at 21:01 i lost my ip, then i had to do a renew.

It can take up to 5 minutes to restart dhclient depending on if check_reload_status is running.

So if you still have trouble please check that check_reload_status is running from a shell by doing:

ps awux | grep check_reload_status

Also, cat /etc/crontab | grep check

I found yet another problem. This WAN DHCP issue has been nothing but fun!

Try out a recent snapshot atleast an hour from now.

Yes the problem still exists and we have been racking our brains out – literally.

At this point reinstall. My dhclient has been rock solid for over 24 hours!

Selective · Feb 25, 2007, 12:03 PM

mine to, but only after i pushed the renew button the first time it died, strange

sullrich · Feb 25, 2007, 10:01 PM

Make that 48 hours. And Vescovo has been running it for 48 hours on 2 wans with 180 second renewal time.

This issue is fixed for sure and verified now by 3 different people.

Selective · Feb 25, 2007, 10:29 PM

Thats nice to hear =)

But just one thing, could you reboot your pfsense and monitor it again ?

My issue always come after a while when pfsense is rebooted, and the issue disappears after i push the renew button.

sullrich · Feb 26, 2007, 12:06 AM

Yes, it has been rebooted once.

yoda715 · Feb 26, 2007, 4:20 AM

Mine has been steady for the last 2 days as well.

ThomasF · Feb 26, 2007, 5:27 PM

I also get the dhcp problem only one time after each boot.
I have also been losing functionality of the DNS forwarder since upgrading to 1.0.2-0221 from 1.0.1 but that seems to have vanished since I started out with a fresh config.

Selective · Feb 26, 2007, 7:32 PM

as i said, happens one time after reboot, then press renew and the issue disappears,
there is something magic about the renew button that doesn´t happen in the reboot process =)

sullrich · Feb 26, 2007, 8:13 PM

I have rebooted countless times and cannot reproduce this. Sorry.

ThomasF · Mar 8, 2007, 5:25 PM

I don't think I am affected by that bug, It's much worse for me :(
After about 12h uptime (this time) the interface went down, when i renewed the ip adress nothing worked correctly, I could not do nslookup. Didnt try anything else. I restarted the DNS forwarder, it made no difference. I'm not sure about this but my hardware could be very incompatible with pfsense 1.0.2/fbsd 5.2.

Feb 27 08:43:36 kernel: arplookup 66.249.93.99 failed: could not allocate llinfo
Feb 27 08:43:36 kernel: arpresolve: can't allocate route for 66.249.93.99

Just wanted to say this, I don't have time to look further into this at the moment.

EDIT: SNAPSHOT-02-27-2007 solved my problems

This is not the same problem. Please start a new thread. And for the record, we do not use FreeBSD 5.2.

Any possibility that you try to run PPPoE along with Multiwan like in the following thread?
http://forum.pfsense.org/index.php/topic,3554.0.html

If this is true please add your comments to this thread. If not please start a new one like Scott asked you to do.
