Keep loosing WAN IP Address - dhclient does not seem to do update
-
Okay, I can confirm that the new snapshot is not working in this issue.
I have a problem with my ISP that my IP is dropped 5-10 times a day. I don't believe at the moment it is because of pfsense.Anyway, this makes me a great candidate for testing if pfsense is renewing my ip address when it detects it's down. I can say it dosen't. If I press the "renew" button manually, I get the interface up.
My WAN interface is dc0
My LAN interface is xl0Dec 15 08:36:23 check_reload_status: updating dyndns Dec 15 08:36:22 dnsmasq[7736]: using nameserver 217.75.96.11#53 Dec 15 08:36:22 dnsmasq[7736]: using nameserver 217.75.96.12#53 Dec 15 08:36:22 dnsmasq[7736]: reading /etc/resolv.conf Dec 15 08:36:22 check_reload_status: reloading filter Dec 15 08:36:22 miniupnpd[16371]: received signal 15, exiting Dec 15 08:36:19 php: : Resyncing configuration for all packages.

i have the same problem, and i have done this (no warranty!):
edit /etc/rc.newwanip
and in the beginning of the file i added:if($curwanip == "0.0.0.0") {
log_error("Failed to update WAN IP, restarting dhclient.");
exec("dhclient rl0");
}
–----------------------------------------------------------------------------------
Replace "rl0" with you WAN interface!
It would look like this:/* WAN IP address has changed */
$argument = str_replace("\n", "", $argv[1]);
if($argument <> "") {
$curwanip = find_interface_ip($argument);
$interface = convert_real_interface_to_friendly_interface_name($argument);
if($curwanip == "")
$curwanip = get_current_wan_address();
} else {
$curwanip = get_current_wan_address();
$interface = "wan";
}
if($curwanip == "0.0.0.0") {
log_error("Failed to update WAN IP, restarting dhclient.");
exec("dhclient rl0");
} -
have done some research, and it seems that the problem is dhclient and not pfsense, this guy is not using pfsense:
http://lists.freebsd.org/pipermail/freebsd-current/2005-October/056279.html
-
That was from 2005. Since then dhclient was replaced with a version from OpenBSD.
-
well,, the error is the same:
"short write: wanted 21 got 0 bytes" -
well,, the error is the same:
"short write: wanted 21 got 0 bytes"Yeah, that's very strange. Just to make sure, you are on the latest testing snapshot?

}THANKS SO MUCH!
This works like a charm. My ISP drops my IP from time to time, it was annoying because pfsense doesn't auto-renew it for whatever reason. I'm running in vmware. It works fine now! I can see it in the system logs as it happens.
-
Nice to hear it worked !! :D

Yes, im using 2006-12-14 right now, maybe its time to upgrade dhclient to 3.0.5 if its possibly ?? or even replace dhclient.
-
yeah, definately looks like the same error. What drives me crazy is that the versions before 1.0 of Pfsense worked flawlessly concerning the dhclient Wan IP issue. Was there a version change?
Cheers

Everyone having problems please replace /etc/rc.newwanip with http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/rc.newwanip?rev=1.21.2.23;content-type=text%2Fplain;only_with_tag=RELENG_1
Let me know.. Thanks!
-
Sorry to say, but I have tested another firewall and all my problems disappeared.
The thing about my ISP is changing my IP a lot.. Yea, it disappeared. Clearly it was pfsense. On the new firewall I have had the same WAN IP since the installation ~2 days ago.The weird part about this is that pfsense has been working before without problem. All problems started when I changed my ISP. So.. again, not expert, but I believe ISP have different ways to give IP's and pfsense can't handle them all in a correct manner.
On the new firewall I can see in the logs that it comes false dhcp offers from time to time on the WAN. The new firewall just drops this. Maybe pfsense doesn't? Anyway, I have no clue… -

I don't know if this new script fixes the Loose IP Problem. But after replacing the old version with the new one I had problems with my OpenVPN. Always the script tried to re synced the OpenVPN, I received a error:
Port [undef] 1194 already bound
I use the pfSense-1.0.1-Embedded.img.gz with just changing the /etc/rc.newwanip to the proposed version.
-
Nextrem: not related, known issue, please see the openvpn threads.
Everyone else:
I have updated rc.newwanip, try this version:

–---------------------------
however, i dont think this script will solve the "short write: wanted 21 but got 0 bytes" error, or does it ? -
It does not solve it, it simply works around the issue for the time being. Anyone else tested?
-
i know, but i think there is two errors,
first, when it failes to update the wan ip, that have been "solved" with the script.
but the second with "short write" will not be solved by this, i think. -
i can confirm that the new script (rc.newwanip) is working great !!! ;D :D ;D
