I am trying to set up squid to make switching proxies easier. I have a laptop which I use at work and at home. At work, I need to connect to the internet via a authenticated proxy. At home, I connect directly to via mobile broadband. So I end up switching proxy settings twice daily, which is just irritating! To solve this I want to set up a system whereby I never have to worry about a proxy - my browser sees a direct internet connection which squid (on my computer) intercepts and forwards either to the mobile broadband connection or to the work proxy (along with the required authentication) depending on which is available. I've read various articles on how to do clever things with iptables and squid, but I don't understand enough of the networking jargon or concepts to know when I need to change to make it work in my situation, or if it is even possible.

View 2 Replies View RelatedI 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 172.16.31.1:3128 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
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?
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.

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.

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.
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?
I am using Fedora 9, I have compile the squid with source code, i also deleted the old RPM of squid. i then edited the squid.conf in /usr/local/squid/etc and set http_port 3128 transparent and allowed in my acl to my local network but the transparent proxy is not working. if i remove transparent proxy then squid works fine. when i try to make it transparent the squid access.log file does not show any request coming to it (no activity). i have also forwarded all the incoming traffic to squid port 3128. Can anybody tell me why my transparent proxy is not functional.

a bit info, the data that stored in database is a keyword to block the website if a keyword in blacklist match with the url that want access by user. if match so then the user cannot access the website.
