Linux how to modify the TCP port range, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

The code is as follows

Echo '32768 61000 "/ proc/sys/net/ipv4/ip_local_port_range

Supplement: temporary port range adjustment

You can use the netstat command to show how many connections are in this state: [in a production environment, it is best to test first and then consider the appropriate range of a port]

The code is as follows

Shell "netstat-n | grep TIME_WAIT

Shell "cat / proc/sys/net/ipv4/ip_local_port_range

32768 61000

If you need to modify echo "start-number end-number", start-number and end-number are numbers in the range of 0-65536 port numbers, 0-1024 is best not to use, usually familiar with the port, if it is a special proxy server, many well-known ports are not used, of course you can consider!

Don't forget to add the echo command to the system startup script so that the machine takes effect every time it restarts
