1. Create a own proxy in there box who has the internet access.

We have two offices suppose A and B. At office A, we use centos 5.3 computer as router and squid proxy server. At office B we use a cisco router to connect to Internet. Computers at office A that has direct access to Internet can access computers behind cisco router at office B using vnc viewer. 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.

I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??
Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??

View 2 Replies View RelatedI have a Debian server running at the gateway level on a LAN. This runs squid for creating block lists of websites - for eg. blocking social networking on the LAN. Also uses iptables.
I am able to do a lot of things with squid & iptables, but a few things seem difficult to achieve.
1) If I block http://www.facebook.com, people can still access https://www.facebook.com because squid doesn't go through https traffic by default. However, if the users set the gateway IP address as proxy on their web browser, then https is also blocked. So I can do one thing - using iptables drop all outgoing 443 traffic, so that people are forced to set proxy on their browser in order to browse any HTTPS traffic. However, is there a better solution for this.
2) As the number of blocked urls increase in squid, I am planning to integrate squidguard. However, the good squidguard lists are not free for commercial use. Anyone knows of a good squidguard list which is free.
3) Block yahoo messenger, gtalk etc. There are so many ports on which these Instant Messenger softwares work. You need to drop lots of outgoing ports in iptables. However, new ports get added, so you have to keep adding them. And even if your list of ports is current, people can still use the web version of gtalk etc.
4) Blocking P2P. Haven't been able to figure out how to do this till now.

View 4 Replies View RelatedI 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.
I followed this guide: [URL] and restart the Squid Server with no errors but when I try to SSH into it:
Code:
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:
Code:
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?

View 3 Replies View RelatedI 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.
