Since a few day's losing the wan (dhcp) ip address

TravisD

I just did a 100% clean install of 2.1. Didn't bring in any old config, just configured a handfull of NATs that I need. No VPN, etc. We'll see how this one goes…

TravisD

At least I seem to be moving the ball around… (Oh, my apologies for spreading this around to multiple areas of the support forum. Since I'm now on 2.1, I'll try and put things here and redirect the others to here. Bad forum behavior, I know - sorry!)

Fresh, clean, no-legacy install of 2.1 -- still fails, but failed differently this time.

Files as they looked before release/renew:


[2.1-BETA1][root@gw.tubas.net]/root(7): cat /tmp/ue0*
fe80::201:5cff:fe22:1281
dhclient already running, pid: 76098.
exiting.

[2.1-BETA1][root@gw.tubas.net]/var/etc(13): cat dhclient_wan.conf 
interface "ue0" {
timeout 60;
retry 15;
select-timeout 0;
initial-interval 1;

 script "/sbin/dhclient-script";
}

No significant DHCP traffic on tcpdump at this time on the WAN interface (filtering on port 67). Removing the filter, I saw normal looking arp traffic.

tcpdump while doing release/renew (at least that works again to restore service!) produced minimal output, but it looks reasonable to me:


23:32:43.335315 IP (tos 0x10, ttl 16, id 0, offset 0, flags [none], proto UDP (17), length 328)
    c-68-48-155-52.hsd1.md.comcast.net.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:50:b6:59:70:f5 (oui Unknown), length 300, xid 0xba01a458, Flags [none] (0x0000)

   Gateway-IP 73.129.106.1
   Client-Ethernet-Address 00:50:b6:59:70:f5 (oui Unknown) [|bootp]

And again the post-renew output from the various dhcp files:


[2.1-BETA1][root@gw.tubas.net]/var/etc(18): cat /tmp/ue0*
fe80::201:5cff:fe22:1281

interface "ue0" {

retry 15;
select-timeout 0;
initial-interval 1;

 script "/sbin/dhclient-script";
}

So, something changed by doing a fresh install of the 2.1 snapshot, but things still seme broken.

abeowitz

Even with static IPs on WAN and OPT1, I still get lots of these in my dmesg logs:

ue1: link state changed to DOWN
ue1: link state changed to UP
ue0: link state changed to DOWN
ue0: link state changed to UP
pfsync0: promiscuous mode disabled
ue0: link state changed to DOWN
ue0: link state changed to UP
ue0: link state changed to DOWN
ue0: link state changed to UP
pfsync0: promiscuous mode enabled

I'm getting small % packet loss, which seems to correlate to the link states. But there's no interruption in web surfing.

I don't have OpenVPN enabled/configured. I do have the export keys module installed, but haven't done anything with that yet.

TravisD

So I had configured a couple of dynamic DNS updaters, but decided to pull them out for one reason or another.

Upon deleting them, this appears in the system.log:


Mar  1 01:05:29 gw php: /services_dyndns.php: The command '/bin/rm /conf/dyndns_*.cache' returned exit code '1', the output was 'rm: /conf/dyndns_wandyndns'travisd.dyndns.org'0.cache: Read-only file system rm: /conf/dyndns_wanopendns'travisd.dyndns.org'1.cache: Read-only file system'

…and the WAN link dies again (loses it's IP address)

Manually trying to remove these replicates the issue:


[2.1-BETA1][root@gw.tubas.net]/conf(12): rm -f dyndns_*
rm: dyndns_wandyndns'travisd.dyndns.org'0.cache: Read-only file system
rm: dyndns_wanopendns'travisd.dyndns.org'1.cache: Read-only file system

Edit: More logs, this is what spits out now when it dies (and before manual recovery via release/renew)

The log extract you posted shows multiple dhclient copies running. This seems like a bad idea - they could easily interfere with each other in unpredictable ways. I think I have seen recent posts addressing this issue. The multiple reports: Feb 28 23:26:06 gw php: : rc.newwanip: Informational is starting ue0. in the original log you posted seem strange in that ue0 shouldn't need to be started (not sure exactly what that started means) immediately after the interface IP address has been set and routes added etc. PERHAPS there is a synchronisation issue between multiple processes and it generally works OK in some systems (slower systems like mine) but doesn't generally work OK on faster systems.

@abeowitz:

Even with static IPs on WAN and OPT1, I still get lots of these in my dmesg logs:

ue1: link state changed to DOWN
ue1: link state changed to UP
ue0: link state changed to DOWN
ue0: link state changed to UP
pfsync0: promiscuous mode disabled
ue0: link state changed to DOWN
ue0: link state changed to UP
ue0: link state changed to DOWN
ue0: link state changed to UP

Its likely that for a time the NICs didn't detect carrier from the devices they are connected to.

@TravisD:

Manually trying to remove these replicates the issue:

Are you running nanoBSD based variant of pfSense? Please post the version string from the home page of your pfSense box.

TravisD

Yes, I'm running a nanoBSD variant. Currently:

2.1-BETA1 (i386)
built on Thu Feb 28 04:26:51 EST 2013

(but over the last several days I've been trying 2.0.1, 2.0.2, 2.0.3-SNAPSHOT, and a few 2.1 snapshots.

This is running on: Intel(R) Atom(TM) CPU 330 @ 1.60GHz

It definitely appears to be a dhclient thing at this point. If I manually kill the running dhclient process and re-start it, things come right back up.

Beginning to believe I have two problems at play. :-\

#1 is that the USB Ethernet adaptor doesn't seem to be very stable. This is the 2nd adaptor I've tried but same make/model as the first. I swapped the former outside (ue0) and inside (re0) interfaces around so now ue0 is the LAN. After a little while, I saw it hiccup again, but since it's static it survived:

The second problem seems to be that the quick down/up apparently plays havoc with the dhclient (what we're seeing in the earlier posts). Related, but different issues from what I see.

I don't consider this fixed - it's just a bandaid solution. What other info can I provide to help here?

i can confirm disabling openvpn doesnt solve the problem. :-[

Yeah, I left it out of my clean re-install and no change.

Since I moved the USB interface to a static addressed interface, I'm still seeing it flap occasionally, but it doesn't get hung up with dhcp like it did on the WAN side. I think that eliminates my cablemodem from the cause of the flapping problem (it was connected directly to the cablemodem; now ue0 connects to a cisco switch).

ue(4) driver problem? usb issue?

When it flaps, it happens quickly enough where I don't even lose any pings when running a continuous test from another host.

TravisD

Sure looks like this would be the bug in question, but seems like the fix may not be working.

i gave up and went back to 2.0.1, hopefully ill be problem free

Since the "bad" interface now connects into my switch, I can look at the other end of the link. No sign of it flapping/bouncing on the switchport side. No errors of any sort, and this is thru a couple of flapping events on the pfSense side:

2.0.1 was rock solid for me before, even the early betas of 2.1 didn't present the problem (but i was updating on a weekly basis, so no beta install had a run time of greater than 7 days). if this doesn't work, the issue is probably a hardware problem on my end, nothing has changed hardware wise, so fingers crossed! :P

Interested to hear how it goes. At some point along the way I tried going back to 2.0.1 as well, but it didn't seem to help. I've swapped out 100% of the hardware at this time, at one time or another. I have two of the USB ethernet adaptors, I'm trying the "other" on in a different host (ubuntu box) looking for signs that it's flaky, and if it seems stable there I'll put to back on the pfSense box again. It's connected to the exact same switch that the one on pfSense connects to now, so that should eliminate switch problems.

I'll provide one of these USB adaptors to one of the developers if it'll help diagnose things!

To add a little more information to this issue. Since the moment I went back to the 2.0 series, with identical setup (and used the 2.1 config on the 2.0 installation) I did not suffer from any netwerk droppings or loosing the wan ip address.

And for the first period I was running 2.1 beta's there was not a problem either. It occured somewhere 2nd half of februari and the moment I started this topic.

So unless in that period there was a kernel update I think that (at least in my case) it is not a driver issue, but something that changed in the behaviour of the dhcpclient / handling of signals. Guess it is a by product of another fix, as everything was smooth before.

my situation is exactly the same, the 2.1 betas began having issues mid feb, and 2.0.1 and 2.0.2 have been problem free for me. currently on 2.0.2.

TravisD

Slight update on this. After a couple months away from using pfSense I decided to give it another try. Same hardware as before - this time the USB Interface is my "inside" NIC.

Same behavior - ue0 starts flapping for no apparent reason, and it never recovers. I have to reboot to bring it back. I even locked the speed/duplex down on the Cisco switch that the inside USB NIC plugs into.

Back to the Airport Extreme for me, sadly. I love the extra capabilities that pfSense brings.

Zorac

good info, i was thinking of trying it again, but I guess not. i tried 2.0.3 when it came out had a similar issue, no issue with 2.0.2 though, been running it (2.0.2) fine for the last few months.

TravisD

I still suspect that it's something to do with the USB Ethernet driver, since the flapping problem follows it. I still think there's two problems with it not recovering correctly when it returns. The first time it lost it's (static) LAN address, re-plugging the USB ethernet adaptor restored the IP but not the other services like routing or the gui. (Had to reboot)
