"I get this message "target localhost:81 not
allowed in cachemgr.conf" But that doesn't make sense. My
cachemgr.conf has this "localhost:81 Allow from localhost only." as
it's only line."
I found I had to chmod o+r cachemgr.conf to get it working properly.

Esteemed Squid hackers,
I've been using squid with good results at a site for about 6 months.
Then, all of the sudden, things have gotten real flaky. I've checked
everything I can think of but the problem persists. I've rewritten
the rules (or added a rule) to simplify trouble shooting. Basically,
if you are in the local subnet you *should* be good to visit anything
on the web using the cache.
Here is what happens...
We have about 30 users at any given time. The typical user is Window
XP Pro with IE. Any one of them (it appears random) may get a time
where squid stops working for them. We go visit the computer they are
working at and before we can really do anything squid starts
responding again. The logs show nothing interesting. The access log
in particular shows no attempt to access anything (no HITs or MISSes
etc.) for that user. It *seems* (and I can only say seems) to happen
more frequently when opening a new browser. That caused me to wonder
about ntlm, samba, and auth in general but even after shorting out
those things the problem remains.
The server is running iptables with traffic between the box and LAN
wide-open and those rules haven't really changed lately anyway.
Also, I have not been able to get the the cache manager. When I visit
the cachemgr I get the login screen and all seems well. After
changing the port to 81 (my server is running on that port) and
hitting "Continue..." I get this message "target localhost:81 not
allowed in cachemgr.conf" But that doesn't make sense. My
cachemgr.conf has this "localhost:81 Allow from localhost only." as
it's only line.
Below is my squid.conf and a bunch of system info. *Any* help would
be very, very appreciated. I'm at the end of my rope here!
Thanks again,
Gabe
P.S. Naturally, I would be happy to provide any additional information
that may be helpful in figuring this out.
