Http://os.51cto.com/art/201409/450886.htmMany system administrators today use command-line tools such as Ifconfig, Route, ARP, and Netstat (collectively referred to as Net-tools) to manage and troubleshoot various network configurations. This type of tool originally originated in the BSD TCP/IP toolkit and was designed to configure the network capabilities of old
If you use Linux long enough, then you naturally know that some tools come and go. The 2009 Debian Developer Mailing List announced the abandonment of the lack of maintenance of the Net-tools Toolkit. To this day net-tools is still used by some people. In fact, you can still use the ifconfig command to manage your network configuration in Ubuntu 14.10. However, i
Use protocol analysis tools to learn TCP/IP
I. Preface
At present, the speed of network development is very fast, and more people are learning the network. People with a little knowledge about the network know that the TCP/IP protocol is the basis of the network and the language of the Internet, it can be said that there is no Internet today without the TCP/
network attacks. This is good news for us when there are some important data that we need to protect or prevent from listening, because Windows 2000 is already built into this feature, and we no longer need to use other tools to do that.
Because it is a symmetric encryption of the data at the IP layer and encapsulates the entire IP packet, there is no need to se
We may encounter such a problem when preparing the computer's network connection. Using some network diagnostic tools provided by the Windows operating system, we can often find the crux of the problem to solve the problem. This article describes several practical network test commands in detail:

Does your network often fall out of line, does the IP conflict often occur?Are you concerned about communication data being monitored (e.g. MSN, QQ, EMAIL)?Is your network speed limited by the management software (such as aggregated network management, Peer-to-peer Terminator)?Do you suffer from all kinds of ARP attack software (such as n

The service is a new feature in the Windows 2000/XP/2003 operating system. It is directly associated with the "Local Connection Properties" dialog box and is "Network Connections ". Therefore, as long as the service is stopped, the "Local Connection Properties" dialog box cannot be opened, and the IP address cannot be modified.

Comments: I recently used an automatic IP Security policy setting tool on the server. The server is a web site with 80, 20, and so on. The server installs the eset anti-virus software (nod32) with a firewall. The system starts the firewall and only allows the corresponding port.Then directly run the "Win server filter policy .exe" (suitable for servers), but after the operation, 3389 cannot be connected. At first, the firewall or the anti-virus firewa
