Squid3 can't find libmd5.so.0

marcelloc

This is a workaround to get squid 3.4 working o pfsense 2.2(amd64) until pbi build are ok for this package.

This is not supported by core team! Use at your own risk!

First install squid package from pfsense gui
Next, we need to install pkg on pfsense 2.2, this can be done via console with

pkg install axel

when it asks to proceed(proceed with this action?), you can cancel it if you do not need axel on your system

kill and uninstall any running squid daemon

killall squid
pbi delete squid-3.4.10_2-amd64
rm -rf /usr/pbi/squid-amd64

if you have applied any patch or symlink while trying to run pbi squid version

rm -f /usr/lib/libmd5.so.0
rm -f /usr/lib/libecap.so.2
rm -rf /usr/local/etc/squid
rm -rf /usr/local/libexec/squid

create a folder to download squid3.4 package

mkdir /root/squid34
cd /root/squid34
fetch http://e-sac.siteseguro.ws/packages/10/All/squid34_pfsense22.tar
tar -xvf squid34_pfsense22.tar
pkg add squid-3.4.10_2.txz
pkg add squidclamav-6.10_2.txz
pkg add clamav-0.98.5_1.txz

Save config on gui again and test squid.

I'm getting "Signature for pkg not available" after the pkg command

Finish the pkg install axel cmd

Will the same procedure work on 2.1.5?

@mhab12:

It wont work on 2.1.5. The files that marcelloc complied are for freebsd10 amd64. 2.1.5 was built on 8.3.. Squid3-dev works on 2.1.5

Transparent proxy still does not work :(

@mhab12:

On 2.1.5, install squid3-dev package. I uses squid 3.3.10

Maybe related to some 2.2 RC issues, not squid itself.

Check if you don't have this error on your system logs

tracking this issue I've found this:

trying a manual fix:

and check_reload_status seems to be ok again

I've opened a redmine for it, so core team can check this issue

I can confirm that error. It was also accompanied by sshd being unable to start. Reverting changes didn't help, but reinstalling the snapshot fixed sshd. I will try the fix you described sometime tomorrow. Thank you!

I ran into a small problem after following your steps
"(squid-1): Cannot open '/var/squid/logs/access.log' for writing. The parent directory must be writeable by the user 'proxy', which is the cache_effective_user set in squid.conf."
I was able to 'monkey' around with winscp to change permissions, not sure what I did but got past that. What would be the correct way of 'doing it right'

transparent proxy still not working, under the real time tab this is what I see

fetch squid34_pfsense22.tar again. I've changed a compile option to include only pf transparent proxy.

remove squid package and reinstall it

pkg delete squid-3.4.10_2

pkg add squid-3.4.10_2.txz

jeepster

marcelloc, it appears to be working now, websites are loading and the log looks back to normal - thanks!!

Pakken

Talking about transparent proxy, latest 0.2.2 package works on Pfsense 2.2RC.

I still can't get squid 3 reverse to work, which is basically the main reason why I'm using squid3.
Same settings on 2.1.5 work like a charm.

Thank you for all the efforts you are putting in fixing this.

/chapeau!

Cino

I haven't tried reverse proxy yet which is another feature I use from squid but I start-up another instance of squid using a conf i've created. For me, it keeps the logs separate since I use proxy for logging with lightsquid.

Anything in your system or squid logs that could pin point the issue?

Pakken

Nothing particular that could point me in the right direction so far.
To be fairly honest, I didn't test it like it should be so can't say much so far.

From what I've seen it will always try to forward pfsense webgui on the external FQDN, regardless of what you've set on the backend servers/redirets/mappings etc.

Again, I doubt it's a matter of settings since the same net, same webservers and so on are working right now on 2.1.5.
Will try to provide you some more informations as soon as I can.
Cheers ;)

Cino

just a wild guess, compare your advanced settings under system. I think you have to disable the web GUI redirect

I'm not having as much luck unfortunately. I've updated to the latest pfsense 2.2 release, removed squid3 package, recursively deleted /var/squid and re-installed squid3 and it is not working properly. With transparent proxy enabled it is passing http traffic (vs. error pages before) but the access.log is empty (not created actually) and the cache.log has a single entry in it from the installation:

2015/01/10 12:24:58 kid1| Creating missing swap directories

am I missing something here? I'm not running squidGuard or havp in conjunction with this, just attempting squid3 in transparent mode.

Cino

Check the folder permissions for /var/squid/logs. Make sure it's set to proxy:proxy. I ran into this earlier on my test box. After correcting the permissions, the access.log was created and started to log entries. I don't use transparent mode, but I don't think its related.

jeepster

trouserless, install squid package from pfsense gui - 3.4.10_2 pkg 0.2.2 its been updated tp working. Once I configured the settings I had to stop and restart the service to get it going

That's the first thing I've checked.
The reverse proxy part seems to be broken, at least for me, at the moment.
