The chat was written by Karl Fox. Read the rest of this entry »

Linux than in Windows and most other competitors, is more suitable for server use. The specific breakdown of the top five reasons for it.

1. Stability:

As we all know, Linux system can run continuously for several years did not fail; In fact, many Linux users have never seen a crash. This is for each type of users is very great, especially for those who brought down the disastrous consequences for small and medium enterprises; it was a very special value.

Linux can also handle a large number of running a one-time process, than the number of Windows can handle much more. In fact, such a thing, and soon reduced the stability of Windows systems.

Then there is a need to re-start time. However, in the Windows configuration changes, they usually need to restart - which led to the inevitable downtime, and Linux generally does not require a restart. The occasion of the system is running, almost all of the Linux system configuration changes are able to operate, but also does not affect other related services. Read the rest of this entry »

Sharing an Internet Connection

This is intended to allow you to use an Internet connection (working for instance with the protocol PPP) with the routing of IP packets through the machine connected to the Internet.

Routing IP packets

Suppose a class C network (254 IP) as 192.168.0.0 with a subnet mask is 255.255.255.0
To configure the gateway, you must know the number of the core 2.0, 2.1 or 2.2, 2.3 or 2.4. The tools are different. Read the rest of this entry »
