(Network monitoring tools album network law enforcement officer latest version: v2.63 applicable platform: win9x/nt/2000/xp software authorization: shared software size: 1571kb software introduction: "network law enforcement officer" is a LAN auxiliary management network monitoring tool. At present, the latest version is v2.63. Through the network underlying protocol, it can penetrate each client firewall to monitor any network device (mainly refers to various computers, switches and other network devices equipped with IP addresses) in the network. In addition, it uses network card address (MAC) to identify users, with high reliability; The software itself occupies less network resources and has no adverse impact on the network. The main monitoring functions are as follows: 1. Record online users in real time and archive them for future reference; 2、 Automatic detection of unregistered host access and alarm; 3、 Limit the IP of each host to prevent IP theft; 4、 Limit the connection period of each host. According to the different settings of the administrator, other functions of the software can be expanded to automatically monitor the LAN in real time. For example, the automatic management of illegal users can isolate illegal users from some hosts in the network or the whole network. No matter what kind of firewall the hosts in the LAN run, they can not escape monitoring and will not cause firewall warnings. The disadvantage is that when some switching networks with "layer 3 switching" function are opened, they cannot be monitored normally, nor can they monitor other LANs across routers, gateways and other devices.
