I really don't see how it could not work.

Run this from a shell:

cat /sbin/dhclient | grep reload

What does the results say?

Selective · Feb 21, 2007, 7:04 AM

it does not say anything:
–----------------------------

Enter an option: 8

cat /sbin/dhclient | grep reload

Binary file (standard input) matches

Can someone else please test? This absolutely works for me after 20 hours when normally it would break in 30 minutes…

Works fine for me, only lost my ip 2 times, and that was before the latest snapshot.

Great! Almost started to go insane, because I know this fixed my issue. Please, someone else test?

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.

sullrich · Feb 21, 2007, 10:31 PM

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

sullrich · Feb 21, 2007, 11:01 PM

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.
