Squid problem (TCP_MISS 504)

Hello everyone.

I just finished installing/configuring squid on a Ubuntu 8.10 server, and im having the following problem:

Clients time-out when trying to access any webpage - access.log gives me:

179383 192.168.0.1 TCP_MISS/504 2898 GET http://www.google.com/ -
DIRECT/209.85.193.104 text/html

after reading about it, i thought adding no_cache allow localnet to my squid.conf file would fix the problem, but it doesnt (I already have an ACL saying localnet = 192.168.0.0/255.255.255.0 and an http_access allow localnet in the same config file)

Anyone know what might be the problem?

Thanks Deividosn

I get paid to work with Squid, alas. It means that there wasn't an entry for it in Squid's cache at the point squid tried to serve the page to you. Generally you would fix this by rebuilding Squid's cache, as in:

squid -z -S

Already did that - just did it again just incase, and it said all folders already exist (/var/spool/squid3/0X exists) - my cachedir is configured as cache_dir ufs /var/spool/squid3 2048 16 256 btw.

Im guessing it is not forwarding the request (actually caching the files) - how can i check for that? or thats nonsense?

Right. In that case it's likely a firewall issue. Squid still listens on port 8080 by default -- is that even open? At this point I would want to see your squid.conf file (grep -v '^#' squid.conf first though, please!) and your cache.log file for squid.

woohooo :)

It worked.

Basically my proxy was configured to use another proxy (internet -> old proxy -> new proxy -> client) - that required authentication and everything - looks like that wasnt working alright (not sure what was wrong tho), but when i changed the proxy im configuring to another ip, bypassing the old proxy (that will be retired soon), all worked fine :)

Thanks Thomas
