Test the UTP Port is open

Test TCP port We can use Telnet IP port to verify that the port is listening properly, but what about the UTP port?

Use the Telnet test as follows:

[[Email protected] ~]# Telnet 192.168.18.120 514

Trying 192.168.18.120 ...

Telnet:connect to address 192.168.18.120:connection refused

Apparently, Telnet was rejected.

Using NC to test

[Email protected] ~]# Nc-uz 192.168.18.120 514

Connection to 192.168.18.120 514 Port [Udp/syslog] succeeded!

-U UDP mode

-Z using I/O mode, only when scanning the communication port
