While trying to retrieve the [URL]...The following error was encountered: Access Denied. Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.


ZON-BFC0 is the name presented in my wireless connection, plus the actual ip I'm using there is the ipv4 I found with a quick "ipconfig" search on DOS.

Debian :: Winbind Error After Reboot On Proxy Squid With Ntlm_auth

Oct 18, 2010

I'm running a squid server on debian lenny with ntlm_auth.

Everything is working good after following those two tutorials : [url] and [url]

As all was working perfectly i decided to rebbot my server, and after reboot the ntlm-auth was not working anymore.

When i tried to run the command "wbinfo" with many options i had this error message "error looking up domain users" or"error looking up domain group" so i think that the problem deals with winbind module.

I know that proxy user needs rights and that after reboot the rights are reseted, so this problem doesn't come from here.

And when i try to open IE with a client i have this "cache accesss denied" because the ntlm_auth wasn't done.

I tried to restart all services (samba,winbind,squid) without any success, only the "kinit" command is still working...

What is going on with winbind when the server is rebooted ?

Server :: Make Squid 2.6 Stable As Transparent Proxy Server?

Dec 22, 2010

I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet

Fedora Servers :: Squid 3.1.1 Proxy Server Will Not FTP

May 11, 2010

I have 4 servers running squid/3.1.1 proxy server. Since the latest version I can no longer FTP. I have posted this problem in multiple places but have received almost no response. I've found several other post to this problem throughout the Internet which have also gone unanswered. So, once again, I thought I'd give it a try. As I said "I have 4 servers running the newest version of Squid". When I try to access an ftp, any ftp, I receive an error (check attached image). This was never a problem until just recently. Squid should work perfectly find with ftp, it is not a strictly http proxy.

I turned my firewall off just to make sure, still had the same issue. If I jump directly on the server itself with no proxy settings set in the browser it will work fine. As soon as I set the browser setting to access the Squid software I get the same error. I've included my squid config (which is unchanged from the default settings), maybe somebody better versed than myself can point out an obvious flaw. Everything else seem to work just fine, it's only FTP that's a problem.

Ubuntu :: Setting Up Squid Proxy Server?

Dec 28, 2010

I followed this guide: [URL] and restart the Squid Server with no errors but when I try to SSH into it:


ssh -L 8080:squidserver:8080 user@squidserver

It just hangs there for a long time, not timing out and eventually (after a long wait) I get this:


ssh_exchange_identification: Connection closed by remote host

What could be the problem? I can SSH normally into the computer, but not into the proxy server. Do I need to forward the 8080 port on that network?

But computers at office A that can use internet only through squid proxy can't access computers behind cisco router at office B. Is there any way so that I could allow squid clients to access computer behind cisco router at office B using vnc viewer.

Server :: Improving Squid Proxy Performance?

Feb 4, 2010

I am starting to get bottlenecks in the loading of webpages via squid. It is not the actual playback of video that has performance issues, this is very good. However, when a webpage is first requested, it is the initial response that takes more than a few seconds to load the page. I am wondering how to troubleshoot the issue as I don't know whether it is squid, the dns lookup, the number of users, RAM, or the bandwidth. Bandwidth seems to be the least likely since the server has a high bandwidth and video streaming appears to have no problems. I do not have caching turned on yet, which would certainly help because I do not want to cache flb, mp3, etc. files and the last time I turned on caching the performance was actually worse. The slow loading of pages has only just beguin to creep into the performance, it wasn't an issue before.

I readed the Docs on the squid page but the above rules can't be reproduced to 3.1 and i don't wish to use such rules to make it transparent or hidden so i want some help to figure out why it inst transparent.

Server :: Squid As Reverse Proxy - Too Slow ?

Mar 16, 2011

I've been using squid-cache for a long time for authentication/authorization. It has work fine for years, but now it starts working too slow only in one computer (the others, works fine).

It's configured as a reverse proxy.

I see it can be a DNS problem, but the computer is configured with the same dns servers in resolv.conf that the other computers have.

I use squid 2.6.stable14 on RHEL 4.4.

If I restart the service (service squid restart) it works fine, but 15-20 minutes later, the problem repeats.

Server :: Squid Intercepting Proxy On Bridging PC?

Mar 22, 2010

I am trying to set up squid as an intercepting proxy on a bridging (as opposed to NAT/routing) PC. I followed this guide on freshmeat - however, when I started squid it said the httpd_accel_* lines were unrecognized, so I commented them.

I have the bridging side working alright, but when I try to access a website from a machine using the bridge, Squid gives an error saying it cannot find the site, and only listing the non-domain part of the URL.

For example, if I try to go to [URL] , the Squid error page says it cannot find the server /questions/

I'm using Squid 3 on Ubuntu Karmic. (I don't have any reason for using Squid 3 over 2.whatever, I just picked the newer one).

Also, a side-question - since no doubt someone will ask for my squid config file, what's an easy way to strip the comments so it's not half a mile long when I post it?
