Dansguardian 2.12.0.3 Signal 11

tj.krause

Hi guys,

So I recently upgraded our pfSense install from 2.0.1 to 2.0.3 and upon reboot it reinstalled all the packages as well. When it did Dansguardian was upgraded from the 2.12.0.0 package to the 2.12.0.3 package. However, it appears as though the Dansguardian package is now broken or I have a library with an incorrect version that Dansguardian does not like. Here's what my log looks like and is causing the Dansguardian forked processes to crash causing a slow down in internet connection. We also did not change our configuration when updating and I'm wondering if there were some new options that is causing it to bug out on us. The service starts up fine and seems to run for about 10 minutes before generating the errors.

Anyone else having this issue or can help me troubleshoot this?

Did you updated dansguardian binaries after 2.12.0.3 to fix web upload bug?

Marcelloc, yes I did try the package in this thread http://forum.pfsense.org/index.php?topic=58442.0 however it did not resolve the signal 11 issue.

tj.krause

I'm thinking about just rolling the Dansguardian package back to 2.12.0.0 however I do not see a tbz for this version under files.pfsense.com anyone know how I might roll this version back or how to install an older PBI?

tj.krause

Nevermind I just downgraded Dansguardian to 2.12.0.2 and it is working without an issue. Seems like there is a problem with the 2.12.0.3 package just an FYI.

I'll try to compile latest alpha version to do some tests.

I've pushed dansguardian non oficial version 2.12.0.5 to my repo.

Marcelloc, I'd like to install the 2.12.0.5 version of Dans Guardian as the sites that I support
are both experiencing the Signal 11 issue with Dans Guardian.
The sites are running 2.12.0.3 v.0.1.8 with your patched DansGuardian binary (to enable web uploads)

I see that the new version that you have made available is a .tbz file which looks like the complete package.

How do I install this over an existing running copy of DG?
Is it a simple case of pkg_add dansguardian-2.0.5.tbz?
Do I need to uninstall DG first and if so what happens to the current configuration files (lists, groups etc)?

Thanks
Neil

pkg_delete current dansguardian package and then pkg_add -r with full url path.

If you are using squid3, then check if dansguardian install process forced squid2 install. If so, reinstall squid3.

And let me know if signal11 is gone on your install with this version.

LokisMischief

have you got an i386 version of this by any chance??

Cheers,

It seems to require squid 3.4 among other things.

Anyway, I get the follwing error when starting it.

Config problem; check allowed values for pcontimeout

Yet to find an error in one of the conf files… I presume its complaining about the proxy connection timeout value... but that's set to 30 by default anyway.

LokisMischief

oops, seems dansguardian needs three new values in the conf file come 2.12.0.4

# Proxy timeout
# Set tcp timeout between the Proxy and DansGuardian
# Min 5 - Max 100
proxytimeout = 20

# Proxy header exchange
# Set timeout between the Proxy and DansGuardian
# Min 20 - Max 300
proxyexchange = 20

# Pconn timeout
# how long a persistent connection will wait for other requests
# squid apparently defaults to 1 minute (persistent_request_timeout),
# so wait slightly less than this to avoid duff pconns.
# Min 5 - Max 300
pcontimeout = 55

First signs are promising, no sig 11 yet.

Well, so far a child process hasn't dropped out, however I now have a load of ntlm failed auth's?

Do you have ntlm auth set? I'ts working and logging some failures or it's not working?

This version is compiled for high load, do you think it's running faster?

I do have ntlm auth set, did have it in conjunction with basic, but it doesnt seem to matter if thats enabled or not.
NTLM auth is working, I am getting usernames in the logs, nobody has complained they cant get on yet… I wonder if its a piece of software attempting to auth..

Well, it seems marginally faster. Still getting the occasional redirect not being followed. I have all the tunables in the dansguardian.conf set for "suggested for large site" settings.

I wonder if I should upgrade squid.

LokisMischief

well, that worked yesterday (despite the ntlm auth errors), but today we are back to the same signal 11's.

I have gone back to 2.12.0.2 for now.

rjcrowder

I also have some of these errors - although it sounds like you're seeing it more often. I did a little googling and it seems that this issue with DG under freeBSD has existed for a long time. I didn't find any definitive answers, but most suggestions for fixing it centered around changing the DG settings - such as max children, max spare children, and max age of children. I bumped some of these settings up yesterday and will let you know the results…
