1. you can use ~ $ Netstat-anp to check which ports are opened. (Note: adding parameter-n will convert the application to Port display, that is, address in digital format, such as: nfs-2049, ftp-21, so you can enable two terminals, 1 corresponds to the port number corresponding to the program) 2. then you can use ~ $ Lsof-I: $

other computers (IP Address: 192.168.1.1, check the status of the port in tcpview. The section in the black text below is truncated from the tcpview. 1. The listening status is in the listening status after the FTP service is started. When the State is displayed as listenin

This topic describes how to recover the common status of the POS port of a vswitch. Many problems may occur during contact and recovery of the POS port of the vswitch.

this time, I found that the normal workstation can access the Internet immediately. From the troubleshooting process above, we cannot rashly use the method of replacing the NIC device to solve the fault if the NIC device is abnormal in the future, this can improve the efficiency of solving network faults, but it cannot take full advantage of the residual heat of the NIC equipment. Let alone solve the fault caused by mismatch of the duplex mode of the NIC. Instead, we should be good at starting

You may often encounter various router problems when working on network engineering. However, in addition to the configuration of a router, a more common method is to view network faults through the router port status. The following is a summary of my experience and I hope it will be useful to you. Check the status of

1. The computer port is the outlet for communication between the computer and the outside world, 2. Run the netstat command in Windows to check the port opened on the machine. Go to the command line and use the parameters a and N of the netstat command. The result is as follows: C:/> netstat- Active connections PROTO local address foreign address State TCP 0
