Networking :: Block Some Sites In A LAN?
Jul 18, 2011I need to block some websites and torrents on my LAN running on mostly WIndows XP pcs and a Windows 2008 domain controller. It's possible to block some sites using DNS in Windows Domain controller, but users have the rights to change DNS and bypass the rule. Editing HOSTS file doesn't workThen I tried using Avast antivirus Site Block feature, but that doesn't work on any browser except Mozilla. We have to use Epic and Mozilla Firefox.We can't use a dedicated hardware firewall due to budget constraints and the fact that we have multiple ADSL lines for internet. No single gateway.

Nov 3, 2009I have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.

View 3 Replies View RelatedUbuntu Networking :: The Phone Can Access The Internet Through The Computer Unable To Get Access To Https Sites, Like Webmails
Dec 31, 2010I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

Ubuntu :: Can't Access Certain Sites
Jun 12, 2011Im having trouble using my wireless usb dongle. I've installed the software and connected to the web, but i can only access a number of websites.
I can access ....., and watch vids and perform searches on google, bing, yahoo and the like. However when i try and access a site that i have searched for it takes me to the internet providers homescreen and tells me to activate my account or top up my account.
I know i have enough GB left as i recently activated my account and i'm able to use the wireless stick on another computer without any problems on all websites. So this leads me to believe that there is maybe a problem with my browser or security settings, but im not sure what to do.

Sep 1, 2011Strangest thing...yesterday my 11.04 box lost the ability to access anything external. I can ssh to the box from outside my network, and all other boxes on my network are fine, but this one box can't hit anything external. If I attempt to ping a site it's doing the same resolution, but no packets are delivered.
Up until yesterday it was running fine, and I didn't make any changes to my home network or install any updates. Totally stumped.
Edit: this is a wired connection with a static internal IP.

Mar 9, 2011I'd like to ask a question on installing software.
I cannot install software using "yum" but I can with the GUI program "Add/Remove Software".
For example, I tried:
It will exhaust all the mirror sites without success.
All the error messages look like:
But I can install "screen.i686" easily from the "Add/Remove Software" GUI and it is very fast.
However, what's puzzling is that I could install some certain packages although I still see the same kind of error messages.
For example,
will work. But in general, "yum" is running very slow and is rejected at every mirror sites.
My settings: I just installed "Fedora 14" (Linux 2.6.35.11-83.fc14.i686) as a virtual machine (using VirtualBox) on a Windows XP (Professional, SP3) host on my laptop (CPU: Intel Core2 Duo), which accesses internet through a HTTP Proxy server since it is behind a corporate firewall.

Also I can access all these sites properly from windows so it is not problem with my internet connection either.
Software :: Automating Access To Interactive Sites Which Use HTML And Javascript
Mar 5, 2011Is there a modern equivalent of "Expect", which was developed for the UNIX environment to automate access to programs which had been designed to interact only with a human?
Now with many facilities only accessible by HTML and javascript, what solutions are there to access such websites from a Perl script for example?
The need to access interactive systems by automated agents is the same now as when Don Libes originally wrote Expect, described well in his paper to the Summer 1990 Usenix Conference, Expect: Curing Those Uncontrollable Fits of Interaction.
I want my computer to access the web - I don't believe I should have to be chained to it by mouse and keyboard before it can interact with web sites. Surely there are some tools for achieving this. I've searched, but haven't been able to find any. Although I'd like to do it from a Perl script, I'd consider any language: C, PHP, anything.

Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10
