| 173495 | 2003-09-10 06:05:00 | Is it ok if the users can access the internet browser, but cannot access anything on the internet? I know of a school where the internet browser is enabled, so students can access the pages on the local intranet at any time, but for the internet to work, the teacher has to "unlock" the internet. Can you list all the browsers you have tried, so we can offer suggestions of other browsers to try. |

| 173496 | 2003-09-10 08:50:00 | The browsers I have tried, mentioned in my first post, are NS7, Fbird0.6, Opera7. Turning the internet off and allowing intranet only is possible, but that affects all users and is not as flexible as allowing selected users and groups access as and when required. |

| 173497 | 2003-09-10 09:24:00 | Yeah, but I was 13 when I first got past that Graham... They were running NetScape on half the PC's and they were easier! I didnt do any damages, but I actually brought up the source for the website and had a looksie at our local libraries. I only had read-only access over the LAN anyways ;-) Still, I would also vote that its an interesting idea, or simply changing DNS settings on PC XYZ at a time? I know you can use Reg. keys to change it.. surely theres something to be thought of there? |

| 173498 | 2003-09-10 10:26:00 | I'll give you a quick run-down of a setup at a school I know of. A proxy server running Squid on a Linux machine controlling a Jetstream connection. It is used for caching and tracking user access to websites. It is configured so that different IP blocks are assigned by default to different machines in different classrooms. When a teacher or the computer tech logs on, the login server assigns that computer a particular IP address which bypasses the "lock" on the internet. When they log out, the computer is returned to default. Basically, an ex-student wrote a C script to control the Squid proxy (I think he based it on an open-source code called "WebLock"). That way teachers can use a web based interface (on the intranet) to "lock" or "unlock" the internet to a particular classroom, or to particular machines. You can alter this setup, so that each user (student or teacher) who logs on has his/her machine assigned a particular IP address. An example would be to have teachers on the 10.1.2.xxx range, and set the proxy to let machines on this IP range bypass the internet lock. Give students in class 12AB (for example) an IP address on the 10.1.3.xxx range, students in class 13BC an ip address on the 10.1.4.xxx range and so on. So basically you get the login server to assign different IP addresses to different user groups. You can then create a program to alter the proxy server and "lock" of the internet to particular IP ranges. I am reasonably sure that the login server (in this particular school it is Win2k Server) is able to assign IP addresses to users when they log in. Otherwise, there is a registry entry which can change the IP address of a computer - but unfortuantely I can't remember it at the moment. |
