Explain to relatives and friends what the series is IP, port, and domain name
IP addresses, ports, and domain names are no stranger to professional people, but they may not be familiar to non-professional people. The purpose of this article is:
First, I want to install "brick house" (in fact I don't know much about it). I want to learn about computer science,

This script is to monitor whether the host is alive in a network segment, whether Port 22 is on, and whether the SSH login can be successfully logged through a unified user name and password, and the host IP that could be logged in is logged to the file.Shortcomings is that I do not know whether to test SSH login, there is a ping address is really slow, but fortunately there is time to write a multi-threade
In order for your system to become an impregnable fortress, you should close these ports,
The main are: TCP 135, 139, 445, 593, 1025 ports and
UDP 135, 137, 138, 445 ports,
Some popular virus backdoor ports (such as TCP 2745, 3127, 6129 ports), and remote service access port 3389. The following describes how to turn off these network ports under winxp/2000/2003:

In the middle of a Cisco switched network, you know the IP address of a machine, how do you find out which port it is connected to? The most convenient and efficient way to make use of Ciscoworks LMS network management software user tracking function, graphical interface, at a glance.

For a variety of reasons, we sometimes need to set up multiple Web sites on an IP address, and in IIS5 we may be able to achieve this goal by simply setting.
In IIS, each WEB site has a unique, three-part identity to receive and respond to requests:
(1) IP Address
(2) Port number
(3) Host header names
In IIS, there are usually two ways to establish multiple indep
