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

TheOtherBastard

I've been experiencing this problem lately and it still has not been resolved for myself either.

ISP: ZoomInternet

I'm not sure my exact snapshot, but it was most recently updated on Jan29.

Any info that I can provide to help get this resolved I am more than willing to give.

Please update to a recent snapshot like I asked everyone else to do.

sullrich

Anyone have an update? Or is the problem finally fixed with recent snapshots?

Selective

do you mean snapshot 02-02 ?? if you do, the problem is not fixed =(
still ending up with "short write: wanted 21 got 0 bytes"

sullrich

Yes, the updated snapshot as of a day or so.

Please provide the entire log file.. As much detail as possible. You can X out IP addresses but I need to see the chain of events from before and after this happens.

Also, for the record, who uses PPPOE and who has just a regular DHCP WAN?

I've updated but still now it didn't stop. Maybe I can turn off then on the router.

I have 2 links:

fxp0 that is our pppoe wan that is used for servers and DMZ;
vr0 which is in opt1 that serves our worksations; This is connected to a router trought a diffrent ip.

I think I had 2 different problems:

pppoe (fxp0) went down from time to time and I think it was solved with some latest update. This was the worst because sometimes we dind't have vpn at weekends. I think it's solved.
now I still have the last problem which the workstations don't have internet with some dhcp problem. There isn't dhcp activated neither on router or firewall.

I have made some more changes for debugging. Please test todays snapshot.

Thanks!

Confirm me that its the pfSense-Full-Update-1.0.1-SNAPSHOT-02-02-2007.tgz dated from today please.

sullrich

No, todays date is the 6th. Images are still building. Check back in an hour.

freax

It's from http://snapshots.pfsense.com/FreeBSD6/RELENG_1/updates/ ? Right ?
There isn't any from today.

freax

It's there now. Thanks.

Hi again.

I did the update but i think I can simulate what's happening.

The firewall interface and router, both have fixed ip's so what I did was unplug then plug again for 2 seconds. Then, no Internet:

Feb 6 20:23:03 php: : Hotplug event detected for vr0 but ignoring since interface is not set for DHCP
Feb 6 20:23:03 php: : Processing vr0 - start
Feb 6 20:23:03 php: : Arguments passed rc.linkup. 'vr0 start '
Feb 6 20:23:03 check_reload_status: rc.linkup starting
Feb 6 20:22:58 kernel: vr0: link state changed to UP
Feb 6 20:22:58 php: : Hotplug event detected for vr0 but ignoring since interface is not set for DHCP
Feb 6 20:22:58 php: : Processing vr0 - stop
Feb 6 20:22:58 php: : Arguments passed rc.linkup. 'vr0 stop '
Feb 6 20:22:58 check_reload_status: rc.linkup starting
Feb 6 20:22:55 kernel: vr0: link state changed to DOWN
Feb 6 20:22:01 syslogd: kernel boot file is /boot/kernel/kernel

The same result before I think.

I will wait that this happens naturaly but this may help for now.

Thanks.

Thanks. Can you update with the latest snapshot and run that again? There appears to be some missing debugging that I added earlier today.

You may want to download the snapshot again to ensure that the code is present.

Thanks!!

Heres my log, from start to end, untouched.

With 08/02/2007 snapshot.
I unplugged the cable and then plugged it again.
I will post soon when it naturaly fails.

I'm experiencing this as well now. Updated to the 2-09 snapshot and still not working properly.

sullrich

Considering that none of the other devs can reproduce this, maybe you can help us nail this down.

yoda715

Aye, Im trying. Looks like dhclient is trying to renew before lease expires. It's throwing everything out of wack. Dyndns, snort, WAN access to my box. Trying to determine pattern.

I like what you guys are doing ;D this is from my pfbox, ISP BBB(Bredbandsbolaget) Sweden 100/10 mbit
