Squid 3.3.4 package for pfsense with ssl filtering

bellera

pfSense 2.1 (not upgraded to 2.1.1)
squid3-dev upgraded from 3.3.10 pkg 2.2.1 to 3.3.10 pkg 2.2.2

Bug for interception

Last lines of squid.conf generated by 2.2.1

# Custom options

always_direct allow all
ssl_bump server-first all
# Setup allowed acls
# Allow local network(s) on interface(s)
http_access allow localnet
# Default block all to be sure
http_access deny allsrc

Last lines of squid.conf generated by 2.2.2

# Custom options before auth

# Setup allowed acls
# Allow local network(s) on interface(s)
http_access allow localnet
# Default block all to be sure
http_access deny allsrc

Workaround until next version

Put at Custom ACLS (Before_Auth) box the lines

always_direct allow all
ssl_bump server-first all

Custom ACLS (After_Auth)

In addition to this, the box Custom ACLS (After_Auth) does nothing.

Rotate Cron duplicated

The upgrade also duplicates the rotate cron. You can see it if you have Cron package installed

0  	0  	*  	*  	*  	root  	/bin/rm /var/squid/cache/swap.state; /usr/pbi/squid-i386/sbin/squid -k rotate -f /usr/pbi/squid-i386/etc/squid/squid.conf  	
0  	0  	*  	*  	*  	root  	/usr/pbi/squid-i386/sbin/squid -k rotate -f /usr/pbi/squid-i386/etc/squid/squid.conf

Delete the old cron containing rm swap.state and look up the new option Proxy server: Cache management: Clear cache on log rotate

Thanks for all the support, worked like a charm, much relieved now, I am not blaming developer doing very good job, but this bug wasted almost two days of working time.

Again my appreciations , you are a life saver.

If you can, please explain cron thing in details.

bellera

Thanks for your good words!

I just created an account to say thank you. I've wasted all my afternoon after the upgrade, trying to guess why ssl bumping stopped to work at our school, but tomorrow everything (included the filter for the students) will be able to continue as expected.

Thanks for your good words!

Also, at school, www.bellera.cat :) :) :) :)

ssl_bump acls were inside auth loop. I'm fixing it right now.

This is still under devel. Current feedback says that's only working on i386 version.

where can i set below parameter permanently.

always_direct allow all
ssl_bump server-first all

Thanks in advance

With squid-devel pf 2.1 multi-WAN loadbalancing doesn't work. Failover works because default WAN gets switched.

More specifically, the floating rule-based setup that used to work for pfsense 2.0.x doesn't work any more. Squid only sends through default WAN, whatever that is at any point.

Marcello, can you please shed light on this? Whether this is squid-side issue or any nuance of 2.1.x?

Also, will it be possible to do loadbalancing with transparent SSL proxy?

Another question: does delay pooling-based traffic management work with transparent SSL proxy'ing?

Hi everyone. I hope you all are having a good night. I'm a newbie with pfsense. For the life of me, I can't even the the squid3 dev package to work at all. It won't work in transparent mode or anything, but the non dev squid3 works like a champ. Any thoughts on where to start to looking?
I'm currently running
pfsense 2.1.2
(works)squid3 3.1.20 pkg 2.0.6 works
(doesn't seem to work at all) 3.3.10 pkg 2.2.2

Thanks

marcelloc

did you followed some squid posts to get it working?

check missing libs?
ipv6 enabled?
netstat -an to see if squid port is closed or listening…

Hello!

Anyone know how to make the built-in antivirus work? c-icap keeps crashing with error signal 11 whenever I enable the AV functions. Or, is there any way to make squid not use c-icap and just use clamav, just like Dansguardian?

Thanks!

You can try old havp or test your squid in i386 pfsense version.

i tried installing squid 3.3.10 dev in 2.1.3v i386
no issues found yet
squid starts after configuration.
looks like the missing lib before where now incorporated in the new version

Anyone has issues while using transparent mode in squid3-dev on amd64? I keep getting Access Denied.

If I configure proxy settings in the browser then it works fine. Just can't use transparent mode. Switching back to squid 3.1.20 works fine.

I think there is a mistake in the reverse proxy config, I was having trouble so I read the squid.conf in pbi/…/etc and I found the directive
round-robin
even though I don't want that since my servers are independent of each other. I suggest either add a checkbox for that or remove that directive. Thanks!
