I recently have tried installing the Squid-cache/proxy server version 3 onto my fresh ubuntu server. So far i have had no luck in the sense of getting connections threw it, mainly because i can't seem to figure out how to get port 3128 (default squid listening port) to listen on the network. I have go threw many configuration manuals and have searched google over and over and i can't find a solution as to why its not listening. I have downloaded a working Squid server but i need to figure out how to do this on my own so we can add this lesson to our class' at work. If anyone knows how to get this program to start listening please help me...

There's 2 parts to that. Firstly, does your firewall allow connections to port 3128? Secondly, did Squid start correctly?

You should be able to tell whether Squid started correctly by looking in its log files. The location is specified in your squid.conf file, but is often something like /var/log/squid. Can you check those and post any errors here please?

Checking your firewall means looking at what rules are set with iptables. Are you running a firewall on the box?

well all i can tell you at the moment is that there are no firewalls enabled on this box. It's kinda just a virtual machine experiment. I will post the log file tomorrow when i get into work.

So, sadly by looking at the log file, I have come to the conclusion that it is doing nothing except that it has created the swap directories.

Creating swap Directories
/var/spool/squid3 exists
Making directories in /var/spool/squid3/00
Making directories in /var/spool/squid3/01
Making directories in /var/spool/squid3/02
Making directories in /var/spool/squid3/03
Making directories in /var/spool/squid3/04
Making directories in /var/spool/squid3/05
Making directories in /var/spool/squid3/06
Making directories in /var/spool/squid3/07
Making directories in /var/spool/squid3/08
Making directories in /var/spool/squid3/09
Making directories in /var/spool/squid3/0A
Making directories in /var/spool/squid3/0B
Making directories in /var/spool/squid3/0C
Making directories in /var/spool/squid3/0D
Making directories in /var/spool/squid3/0E
Making directories in /var/spool/squid3/0F

then nothing after that, so im guessing its not doing andthing when i start it. i check with 'ps -aux' to see if it is running, it shows the directory of the executable for about 1 minute then it disappears. Also, when i use 'netstat -ano' it doesn't come up with the port that it is supposed to be listening on.

Are there any messages in /var/log/squid/access.log, /var/log/squid/cache.log or /var/log/squid/store.log? It's odd that there's just nothing after creating the cache directories.

well that is what shows up in the cache.log, haven't checked the other logs yet. im off work till tuesday, civic holiday monday, ill post other logs then.

well it turns out there is no /var/log/access.log or /var/log/squid3/store.log... I honestly don't see why it is not working, I have tried lots of tutorials on getting it to work.

I just tried squid3 on our Ubuntu Server 7.04 and I get the same results. It looks like it runs for a few seconds, then nothing. I've checked the log files, etc., for a reason but there is nothing. I have also tried Squid2.6 and it works fine. I was just poking around to see what the difference is, and so far, the biggest difference between 2.6 and 3 is that 3 does not work. :-)

just figured it out, its either the permissions on the /var/log/squid folder are too low or it worked when i ran it as a daemon. either way its proxying now.

Wow, that's what it was. I looked at the /var/log/squid3 folder and it was owned by root. I chmod it to 750 and chown -R it to proxy.proxy and it works!
