Anyone have a good squid config they'd be willing to share?

Anyone done any work with squid?

Squid eh?

d00d, squid is really easy to set up, I've been running it @ home for a while for various purposes. I can't say I even recall setting most params in my squid.conf, mine is very generic and plain vanilla... I've been meaning to add some auth to it but haven't got around to it yet. Anyway... if you wanna see it, here it is:

aurora# cat squid.conf | grep -v #

hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
acl all src
acl manager proto cache_object
acl localhost src
acl to_localhost dst
acl SSL_ports port 443 563
http_access allow all
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access deny all
http_reply_access allow all
icp_access allow all
coredump_dir /var/squid/cache

Let it be known that I'm quite sure there are much better configs out there then my half-assed kludged i-just-want-this-to-work-asap conf file. Perhaps others might share!

I just took the RHCE class, and never worked with Squid until last week (it was part of the exam). In most cases, it works almost right "out of the box" as it were. The only parameter we had to change was allowing others to be able to use YOUR squid cache, and I think that's the only change from |MiNi0n|'s "acl all src" entry above, and a line like "default port = 8080" (where the default is usually 3128).

configure args:
--enable-delay-pools --enable-ipf-transparent \
--enable-storeio=diskd,ufs --enable-storeio=diskd,ufs \
--disable-ident-lookups --enable-snmp --enable-removal-policies

--enable-delay-pools - Enable delay pools to limit bandwidth usage.
--enable-ipf-transparent - Enable Transparent Proxy support for systems using IP Filter network address redirection.
--enable-storeio=diskd,ufs - Enable diskd
--enable-removal-policies - Build support for the list of removal policies.
--disable-ident-lookups - This allows you to remove code that performs Ident (RFC 931) lookups.

Reconfigure kernel for squid diskd support

options SYSVMSG

or something like that... this was based on freebsd 4x

With regards to the configure args, are they put in like [code:1:e9e914dbea]make -D --enable-delay-pools --enable-ipf-transparent [/code:1:e9e914dbea] or some other way? I'm having trouble figuring it out.

If you are building from ports then you can read the Makefile to find available options and how to enable them - usually like
make WITH_MY_OPTION=yes install
or, alternately
make -DWITH_MY_OPTION install
Once again, check the Makefile for what the port maintainers have to say. It isn't a bad idea to peruse everything before installing.

If you are installing from source not in ports, then the included README and INSTALL files are you best friends, along with ./configure --help.

That's what I figured, but the Makefile is different to most of the others that have configurable options.

eg: Postfix has stuff like this in the Makefile[code:1:90f2615a57].if defined(WITHOUT_PCRE)
Whereas Squid has no .if defined sections at all

I'm beginning to wonder if you just manually edit the Makefile and uncomment the args you want ......

I've done that before. There have always been a few ports I've struggled with on FreeBSD, when all else fails I just go in and edit the Makefile by hand.
