Change your Network card MAC ( Media Access Control) address Using macchanger |
| Post date: January 4, 2007, 20:01 Category: Network Views: 1316 Comments: 0 |
| Tutorial quote: Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address. |

| Post date: December 12, 2006, 20:12 Category: System Views: 1045 Comments: 0 |
| Tutorial quote: I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose. |

Key-Based SSH Logins With PuTTY |
| Post date: December 10, 2006, 20:12 Category: Security Views: 1563 Comments: 0 |
| Tutorial quote: This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure. |
