Hi,
Am fairly new to Squid and experiencing proxy behaviour I don't quite
understand, though there of course must be a good reason for it all
happening :) We are replacing an old NT 4 Proxy Server with SuSe
running Squid 2.5 With the NT 4 box there was no special configuration
(at least that's what I'm told by the people here). We are using a
Squid parent proxy in another site to go out to the web through. When I
put the parent squid in get out to all sites fine. No restrictions at
all.
I know the question will be why don't you just use the parent all the
time? Well, it's political here, the sibling proxy is to be used for
this site!! When I go through the Squid sibling some sites are okay,
others not. I could list all the ones we can't get out through, but
that would take a long time :) An example is www.gmail.com,
www.hotmail.com, www.webmail.zen.co.uk and other sites where a user has
to do some kind of authentication? The error that appears in the
browser window is (for example):
ERROR
The requested URL could not be retrieved
While trying to retrieve the URL: webmail.zen.co.uk:443
The following error was encountered:
* Connection Failed
The system returned:
(110) Connection timed out
The remote host or network may be down. Please try the request again.
All the other errors also have the web site address with the port 443 at
the end. So I'm assuming this has to do with port 443 being blocked
somehow? I've read "Squid, The Definitive Guide", but can't seem to
find what is needed to open it all up.
Also, downloads seem to timeout. For example, if I go to the firefox
page http://www.mozilla.org/products/firefox/index.html and click on the
Free Download button it eventually timesout.
With Squid I've made the following changes to the squid.conf file:
http_port 80
icp_port 80
cache_peer www-cache.server.co.uk parent 80 80 default no-query
no-digest
http_reply_access allow all
acl bbc_networks src 10.182.0.0/16 192.168.1.0/24 192.168.2.0/24
192.168.3.0/24 192.168.4.0/24 192.168.5.0/24 192.168.6.0/24 http_access
allow bbc_networks http_access allow localhost
The cache.log shows the following:
