Today many tools are available for performing Server Administration. In this article, lets have a check with few of the top Server Administration tools.

IP address spoofing or IP spoofing is the creation of Internet Protocol (IP) packets with a source IP address, with the purpose of concealing the identity of the sender or impersonating another computing system. Its a phenomena in which attackers changes or replicate a IP packets. In order to dig deep lets understand some basic concepts.

In internet the connection between two computer takes place using TCP/IP protocol. In which data needed to send from one computer to another is broken down into pieces known as packets. These packets are numbered when broken down so that they can reassembled at the end or receiver. Each packets have two parts header and body. Body stores the message part and Header stores the metadata for the packets such as source IP, destination IP, sequence number, TLL etc. These metadatas are used in the destination for the authentication of the connection or to identify the source of the request.

We can set up Scheduled Tasks in Plesk by doing the following:

  • Log into Plesk

The user you are logging in with should have enough permissions to create a scheduled task. Windows Shared customers automatically have permission, and the Admin user for Windows Dedicated Servers automatically have permission. Additional users created by the Admin on a Windows Dedicated Server may or may not have permission to setup scheduled tasks, depending on what permissions you give them. (more…)
