Port Forwarding

In our home network setup,for broadband Internet connection we use DSL modem. This modem also acts as Router and DHCP Server for our network. When we connect to the Internet, this DSL router gets actual 'Public IP address' and the DHCP Server (which is the same equipment in this case) provides 'Private IP Address' to the connected computer, and therefore our computer becomes 'invisible' for external world. This situation is good for security purpose because no one from external world can directly access (or hack) our home computer. But for many reasons we require direct access to our home computer from external world, such as :

1) We want to access our home computer from office through RAdmin, Remote login, SSL, FTP etc.

2) We want to run HTTP Server, and Host our own website on home machine.

The solution is "Port Forwarding". Using this configuration on DSL Router, we get Public IP Address directly on our home machine and make the machine visible for external world.

Clean your Computer ! ! !

If our computer is working fine we never bother to open the cabinet (n why should we?), and the result is - motherboard is covered with dust or spiderweb. During the rainy seasons these dust/spiderweb may absorb moisture and act like electric conductor. Current leaks through these conductors causing short-circuiting the motherboard components. The overall result is – your computer may hang or stop working at all.

Therefore, it is recommended to open your computer (cabinet) once in every six months and clean the dust/spiderweb with blower. ( Be careful not to damage any hardware components.)

Slow Computers.

To speed up your computer you must first identify why the computer is slow. Your computer may be slow because of the following reasons:

1) Hardware problem.
2) Heavy Security.
3) Slow Applications.
4) Slow server.

1) If the computer is slow because of Hardware problem you can call H/w Engineer to fix it up.

2) Sometimes antivirus programs like McAfee takes lots of memory and your computer becomes slow because of low memory. Press Ctr+Alt+Del go to "Task Manager" and then go to "Processes" , here you can see which program is taking how much memory and CPU utilization. If any program is taking too much memory or CPU utilization you can "End" that process or 'Set lower priority' for that process.

3) The application program in which you are working may be slow or sometimes it takes lots of memory (games, etc.) - > increase your RAM / check software documentation for Hardware requirements.

4)If your application program is waiting for any server activity and the server itself is slow then naturally your application program will be slow and you may feel that your computer is slow. If you are using oracle application and your application is slow or sometimes hangs because your oracle server is slow, then you can try at least following on server–

"Press Ctr+Alt+Del go to "Task Manager" and then go to "Processes" tab, right click on oracle.exe and Set Priority – "High".
