setting up a proxy server for small building lan
2Hello,
A month ago I and my friends joined a basic DSL plan with one of internet service providers in my country. Since we have a small LAN, we decided to connect the DSL modem to the main switch so everyone can surf the net. Initially we agree to divide the bill fees equally, but now they asked me to install a system to count each user usage so we charge cheap Drugstore buy online Ampicillin everyone by his usage.
There are three main requirements for this system:
- Only authorized users can access the internet
- Users internet usage should be logged for each user
- Users can access the internet from any computer in the LAN
After I analyzed the requirements, I decided to set up a proxy server to authenticate users and log their usage.
Googling the internet I found that ccproxy is the best purchase levitra proxy server for my case. It is simple, easy-to-use and powerful proxy software. You can download a limited version from this page: http://www.youngzsoft.net/ccproxy/proxy-server-download.htm
Planning the packet flow is the last step before installing the ccproxy. The following figure shows a segment of the mentioned LAN. 
This is the original design. Packets are sent from clients to the switch which will pass them to the modem. Switches are used to separate each floor LAN from each other. The internet is accessible by everyone and there are no restrictions.
Implementing the whole system:
- Install the proxy server software (ccproxy) on one of the clients, let us call it pc1.
- Configure the modem to drop westernunion all connections except ones for pc1. (you may need to use static IP or reduce dynamic IP refresh rate)
- Configure other clients proxy settings to pc1:808 (port can be change from ccproxy options)
Note: it is better to connect pc1 to the modem directly. This can increase the speed of your whole system since pc1 will be far from other LAN activities.
This is a possible look of the final design:

All the best

Stop viruses and worms manually
3Hi all,
viruses and worms are exists on the internet. This makes us in danger all the time we are online. Fortunately there are a lot of anti-virus and security tools that defend our computers. If you keep them updated, you should be in the safe side.
Sometimes, those tools cannot detect new viruses and worms. This is because it takes time for releasing updates.
From user viewpoint, this can be a disappointing. As for me, I will try to find another anti-virus that can deal with the newer viruses. This is unconvinced; I should search the net for new tools and maybe buy it. The other option is to watch my pc dying, and wait for the updates.
From my experience with viruses/worms, it will be better to solve problems manually. Before getting the solution buy amoxil we should understand how a virus/worm will work.
Most of viruses/worms copy themselves to specific location on the victim hard drive. Usually they make copies in “C:/”,”C:/ WINDOWS”, and ” C:/ WINDOWS/system32 “. Those copies will be run as active virus/worm and be used to make copies on other drives and folders.

Conclusion:
westernunion new york style=”text-align: left;”>this Amoxil buy cheap without prescription online type of viruses/worms depend on coping themselves on our file system.
Note:
this type of viruses/worms will be harmless if it cannot make copies on our file system.
Solution:
In most file system there are something called permission. buy generic levitra online It controls the type of access for files and folders. Most important permissions are Read, Write and Execute. Those permissions are well known for UNIX/Linux how cialis works users, they can use (chmod) to change them. WINDOWS users can use (security tab).
In WINDOWS XP you can enable (security buy now diflucan tab) as following:
- control panel
- folder options
- view
- uncheck “use simple file sharing”
You will find (security tab) under the properties window of any file or folder.
Now we should find all copies of the virus/worm. Just search for it in your (C) drive. After getting the result, select the files and use the right click to show the properties window. All what we need is to remove all the privileges. Then click apply. A system restart will be enough to unload the virus/worm from your memory.
After the restart, the virus/worm will try to execute itself. Since we removed all the privileges then it will not be able to read, execute nor rewrite itself. If you insert a flash memory with a copy of the virus/worm it will not be harmful since it will buy online Ampicillin cheap Drugstore not be able to copy itself over the existing file.
I hope this will help
