Can anyone provide a quick-start guide to setup a basic Squid? I have read /etc/squid.conf, but I thought it might be better to get a basic squid running and then fine-tune from there.

Also, is a DNS required in the intranet for Squid to run properly?

Thanks !

> Can anyone provide a quick-start guide to setup a basic Squid?

There is not that much for a basic setup in squid.conf:
- specify where the squid cache is,
- specify where the logfiles are, if any (access.log, cache.log)
- allow access from your intranet by an appropriate acl rule.
And you are done.

However, do not forget to initialize the squid cache by running squid with the -z option the first time you start it (but squid will warn you if you forget it).
Do not forget that squid will only start if you have a working internet connection, unless you start it with the correct option to disable dns lookup at startup.

It is not a must, if you have some working dns server IP addresses in /etc/resolve.conf.
However, it may speed you up if you have a local dns server, or at least a dnscache.

and i use INSERT YOUR OWN ROOL
acl heartnet src 192.168.16.1/255.255.255.0
acl user1 src 192.168.16.23
acl usertime time 09:00-10:00
http_access allow heartnet
http_access allow user1 usertime
http_access deny user1
http_access deny all

but its does work, i want 192.168.16.23 user only access internet mornning 9pm to 10 pm.
plz where i am wrong

hello,baki:

acl usertime time 09:00-10:00 is wrong syntax, correct it to
acl usertime D 09:00-10:00
And the last ACL is deny all, so no need to http_access deny user1

thank jiawj to reply,but not apply, maybe its work,
