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

fireseller

Ups, sorry bout that. I watched it for about 10 mins ;) Just starting up again.

Thanks alot.

sullrich

Please run the command again. All known issues hopefully are solved.

sullrich

NOTE: you WILL need to reboot afterwards.

Please run again, I just fixed a few more bugs.

dlawley

Yea… my sense box seems pretty happy again.. thank you sir...

sullrich

Good. Others please test. A new snapshot will be uploaded in a couple hours.

Awesome! Anyone else?

Works great ! I think you hit the spot ! ;D

Great! That's 3-4 people that is now fixed. FreeBSD REALLY needs to take a look at their dhclient. It's obvious that it's subpar to ISC's.

Anyone else?

Merry Xmas and happy holidays!

fireseller

Just updated to the latest cvs… No issue for 2 days. I think the right spot was hit ;)

Happy holidays and again - big thanks for the great work!

I'm new here; so it could be me; but I'm also experiencing the issue. I have to ifconfig up / down every couple hours. I don't see any logs that are showing me errors - any tips on where to look? I installed from the 12-23 build with squid and snort. I also ran the fetch command from above.

I'm all for suggesting it's user error; any tips are welcome. I had a build from early December running and it was up for a couple weeks without issue.

edit with a tiny bit more info - I've looked at the system.log; and it seems to be corrupted near the end.I'm on my second old clunker hard drive; maybe this one's been around the block too many times as well. There's some weird duplication at the end of the log before it turns into an ASCII mess:

Does that suggest anything? I'm not aware of any bootp servers running anywhere. Hm.

Any chance that you are using dhcp on more than 1 interface? The current dhclient-switch doesn't handle multiple dhcp interfaces correctly atm. We need to improve this a bit to handle these kind of situations.

Bad news. Looks like we are going to have to revert back to the previous code. This newer code breaks our multi-wan dhcp.

Just to follow up on my previous information; I see this in the system.log:

Dec 28 08:39:40 chunder dhclient: execve (/usr/local/sbin/dhclient-script, …): No such file or directory
Dec 28 08:39:40 chunder dhclient: execve (/usr/local/sbin/dhclient-script, ...): No such file or directory
Dec 28 08:39:40 chunder dhclient: /y: not found
Dec 28 08:39:40 chunder dhclient: /y: not found

dhclient-script is in /sbin ?

I'm still using the install from 12-23 and I used the fetch from another thread. Maybe I just made a mess…. Maybe I'll copy that over and see what happens; or maybe I'll get a chance to take a better look at it and see what put it there.

Investigating this error is riding a dead horse. We have to go back to the previous dhclient due to multi interface dhclient issues with the isc client that can't be worked around. The next snapshot will be back at the "old" openbsd dhclient.

Hi !

Does the following code work to workaround temporarily this problem ?

/etc/rc.newwanip

if($curwanip == "0.0.0.0") {
log_error("Failed to update WAN IP, restarting dhclient.");
exec("dhclient fxp0");

Thanks in advance.

I don't want to stress anybody but I didn't received any answer and this topic seems to be stopped.
This issue is being solved ?
I'm having this problem too.

Thanks in advance.

No, work has halted. Sorry.

I have commited some work around code to this bug. Please test a snapshot in about an hour from now and see if it works around the issue.

Hi again.

I did the update but I lost my connection at this moment again where it didn't happened with an old pfsense with the same hardware:
