centos develop port for remote connections

I. Background

In the process of program development in C #, we will use the server to be deployed, so we need to open the server port, basically such use TCP / IP protocol, so in this blog we will tell how to deploy a C # program and run it in centos7 above.

Second, the environment

The server uses the server is centos7

Use of C # is a program developed by others on the team

Third, the method

1. Turn off the firewall

Turn off the firewall, so that you can open all of the ports, but this will involve a lot of security issues undesirable.

2. The development of the corresponding port

In addition to using a method other than turning off the firewall, we can also use development on a specific port, so you can be mapped to a port on a specific program.

Here we use the second method

Specific steps

2.1 open a port

Using the following instructions to develop a specific port

# 9641 to develop a port in public areas
firewall-cmd --zone=public --add-port=9641/tcp --permanent

result

Note: Since I've been open, so suggesting a port has been open information

2.2 View

Use the following command to query

firewall-cmd --list-ports

result

2.3 to run the program

Using the following instructions to run a program in C #

# Use instructions mono start a C # program 
mono TTSServer.exe

result

2.4 Program test

2.4.1 using telnet test

Windows10 case of using cmd, and then enter telnet [IP test] [Test port]

With the following instruction

# Personal ip and open the front port 
telnet 114.55.245.217 9641

result

Service-Terminal

Client

2.4.2 Supplementary

In the process used in the presentation information may not find telnet command. This is because the detection method telnet is not enabled by default, but you need to manually open.

1. Access Remove Programs interface
