Software :: Get Squid Proxy Server To Block Websites Using Webmin?
Jul 17, 2010
i have been looking up ways to block websites in linux but most all of the free ones only block the sites the software makers want to (or you can't block just the sites you enter without blocking the sites that it wants to)i need to know how to block only websites i enter with squid using webmin
i was tasked to setup a proxy server to block access to some websites. i'm using centOS 5 and Squid 7:2.6 STABLE21-6.e15...i appended the following and tested the configuration with the supposed server i am using and the it does seem to work but now i'm wondering how i can test it with a client computer..i have 2 LAN cards and i just connected the other to one PC (can a direct connection work or does it need to pass thru a switch or hub)...i just can't figure out how it should be... how do i configure the 2nd LAN card to use this computer as its proxy server?
here i would like to inform you that my company ask me to block facebook site at the work time it is: 08:00-12:30 and 14:00-17:30 in proxy server.i'm still confuse how to do!i need the details configuration in squid regarding how to block the sites
I have recently configured squid proxy server in rhel5 so now I am able to blocking some websites ok, but still I have one problem how can I block gtalk by using squid proxy, one more thing I blocked gmail so now client xp systems are not logging into gmail but still they using gtalk to chatting the things to others. So ultimately I need to block gtalk also by using squid proxy.
I have a problem with sites or domain blocking by squid proxy server in rehl 5. I have trying lots of time but i'm not succed.pls help me how to block sites or domain in rhel 5.
I would like to ask some help and tutorial for setting up and how to configure squid proxy server in my (Home PC Server). I am a newbie in Linux Centos. I already installed in my system the CentOS 5.5 . Now, I want to configure it as my internet server, all of my 4 system running in Windows including the laptop I want to connect through my CentOS pc with username authentication. I assign all IP address by static. see tthe attachement in my set up. [url] I just want to know what I need to change and add in my squid config file. And how can I configure properly my CentOS with 2 LAN card as internet server.
Currently my DHCP Server is working now what i want to have is auto detection of squid proxy in any browser but I still got an error in my dhcp server when I restart it.
My Config:
# DHCP configuration generated by Firestarter ddns-update-style interim; ignore client-updates;
I installed webmin on Debian apt-get install webmin. After installation following message came. Code: Setting up webmin (1.510-2) ... Webmin install complete. You can now login to https://IP:10000/ as root with your root password, or as any user who can use sudo to run commands as root. So I infer that the installation was successful.
But when I do Code: http://IP:10000
I get following error Code: Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error.
I just installed Webmin on this CentOS 5.5 client and would like to know if it's possible to remotely administer the Squid server. The one I'm using for webmin is different from the one where Squid proxy is running.
I am trying to set up Apache and Webmin so that I can access Webmin by going to [URL]. I am using the direction at [URL] under the "Webmin In A Sub-Directory Via A Proxy" section. I had this setup working before, but I think an update of either Webmin or Apache broke it. Now, I can go the the webpage and I see the login screen. However, when I try to log in, I get an error.

Error - No cookies
Your browser does not support cookies, which are required for this web server to work in session authentication mode I have tried adding the ProxyPassReverseCookieDomain and ProxyPassReverseCookiePath directives to my virtual host config file, but it still doesn't work.
We use a reverse proxy to forward a lot of websites via 1 central place.so hould forward to an internal server.I already managed to forward a lot of website correctly, except for this one:hen I type:ttp://blablahblah/smt/webtier-7-11 it doesn't work correctly, but How can I make the first url to work ?
i want to setup squid proxy server at my home. my service provider has ISA server install on its machine. in windows as a client we have to enter proxy settings manually to IE and firefox. but now in squid where i have to define to use this proxy settings. and what about /etc/resolv.conf . my service provider's connection settings are stated as under.:

My Problem is: I want to stop gmail access without blocking https. Yes in my squid proxy normal [URL].. is not accessible. But gmail recently started https service by which user can still get access to gmail. I DONT WANT TO STOP https CAUSE ITS BEING USING BY OTHER PROGRAMS.
i am using centos 5.4, running squid for proxy, i want to block email sending and receiving of proxy users to secure my data. how is it possible that the proxy user can only brows websites but he can not receive or open and send or save as draft to mail box.
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 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
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.
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.
