1. Troubleshooting)Here we will introduce the hardware and software problems that may occur when using vrouters. During the networking process, such as X.25, FR, DDN, DDR, TCP/IP, problems encountered in different network environments such as interconnection with IBM large hosts and solutions .? Troubleshooting tool? What is the Troubleshooting of TCP/IP connection? What is the problem with the serial port

The Internet addresses accessed by computers on the Intranet are mapped to the same legal public IP address. computers on the Intranet can access the Internet by sharing a public IP address. This is the most practical technology. Extended knowledge 1. Enterprises often need to map a port of a specific Intranet computer to a public network. How can I set it on a

Do Zabbix monitoring test has been carried out for some time, the more testing found Zabbix strong, today began to increase the network equipment monitoring test, test results and cacti contrast, there is a great upgrade ready to abandon the former.Because network devices have no way to install proxy clients, the monitoring network uses the SNMP protocol1.

With the development of the international interconnection Network, some enterprises have established their own intranet and connected with the Internet through a dedicated line. In order to ensure the security of intranet, it is necessary to use dedicated firewall computer to prevent illegal intrusion. The router firewall can only be used as a filter and cannot hide the internal network structure from the i

This creates an embarrassing situation for virtual network devices built into virtual machine software. On the other hand, this virtual network device is really not very professional
