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

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.

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.

i don´t know what you guys are using when you are testing the dhclient, but issue still exists:

We lowered the lease time to 150 and used a dedicated testing box.

At this point we cannot reproduce the error. Reinstall.

Selective · Mar 1, 2007, 10:03 PM

i have done so 2 times already =)

sullrich · Mar 1, 2007, 10:04 PM

Well sorry, 4 developers where able to reproduce it prior but under no conditions does it break now.

I don't know what to tell you at this point.

Selective · Mar 1, 2007, 10:22 PM

oh well, i just lay low for a while, and see if others having problems too,

thanks for all your hard work !

I've done a clean install with the latest official update from 08/03/2007 but my logs registeres the following rc.linkup message:

Last 50 system log entries
Mar 9 18:13:30 php: : Incorrect number of arguments passed rc.linkup…exiting.

It's normal ?

Yes, those are debugging statements and looks fine.

Don't know if this is the same issue, but i noticed this yesterday.
Running 1.0.1-SNAPSHOT-03-18-2007 built on Thu Mar 8 22:14:44 EST 2007.

For some unknown reason, my pfSense box lost it's WAN dhcp ipaddress, but my
WatchGuard box connected to the same ISP outlet(i use a switch to get several ports)
did not have any problems recorded, and it to runs on a WAN dhcp. The WatchGuard box
uses something called udhcpc. I don't know if it's better, worse or the same as dhclient.

Pressing the Renew button in Status–>Interfaces had no problem of getting a ipaddress.
I pressed the button around 20:15.

Got this from the syslog(if was not at home when this happened):

Remove snort and see if the problem persists.
