Squid3 can't find libmd5.so.0

mhab12

Will the same procedure work on 2.1.5?

Will the same procedure work on 2.1.5?

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 :(

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

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

@Cino:

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

tried that and it is proxy:proxy

I checked the cache.log because it had grown and found:

I checked the /var/run directory is owned by root:wheel which looks proper.

One other bit of strangeness is that I no longer have access via ssh (I'm using the command prompt feature for the above troubleshooting). I goto the services page and sshd is showed as stopped. I try and start it and it does not. It worked before and it is enabled via the GUI toggle. I checked system logs and nothing about sshd. Is anyone else seeing this issue with sshd? Thanks for the help/ideas Cino (and others)

Are you using the official pbi from http://files.pfsense.org/packages/10/All/ now (i.e via pfsense GUI) or are you still using the manual method?
I noticed that there just have been an update to the pbi and curious to see if works the "official way" now.
squid-3.4.10_2-amd64.pbi, 09-Jan-2015 20:25
Would try it myself but I not at home this weekend…

Cino

I think I figured out the issue with squid.pid… Well at least a workaround for now. This is for the pbi install of 3.4.10_2 pkg 0.2.2 only

I installed a fresh copy of 2.2 amd64... And I noticed this in my log when I would save the squid config

I checked to see if its running and it is. Paths are a little off but its running


proxy   11491  24.0  1.3 112428 26212  -  S     8:50PM   0:00.18 (squid-1) -f /usr/pbi/squid-amd64/local/etc/squid/squid.conf (squid)

root    19788   0.0  0.1  18884  2384  0  S+    8:50PM   0:00.00 grep squid

I then did a search for squid.pid "find /-name squid.pid" It came up empty.. This is bad, because the reconfigure/rotate commands wont be able to hook into the process that is running.

I then ran squid -v and noticed its compiled with option '–with-pidfile=/var/run/squid/squid.pid' but the config file is using /var/run/squid.pid. Is this the reason?
Probably not, thinking it has to be a permission issue, where squid can't create its own pid since its run as user proxy

Here is my workaround until it can be fix in the pbi/package itself

run the following from cmdline


mkdir /var/run/squid
chown proxy:wheel /var/run/squid
chmod 777 /var/run/squid  #not ideal but it works for now

Edit file /usr/local/pkg/squid.inc

On line 943 you will find $pidfile = "{$g['varrun_path']}/squid.pid"; change it to:


	$pidfile = "{$g['varrun_path']}/squid/squid.pid";

Now killall squid or stop the squid service.. Click on Save within the Squid GUI and you should have a /var/run/squid/squid.pid

Click Save again and the timestamp should change for the pid file.

Hope this help!
