In this guide, we will show you how to use the simple Netcat (NC) command to determine if the port on the remote host is accessible/open.
Netcat (or NC) is a powerful and Easy-to-use program that can be used in Linux for anything related to TCP, UDP, or UNIX domain sockets.
# yum Install NC [in Centos/rhel]
# DNF Install NC [in Fedora 22+]
$ sudo apt-get install [in In Debian/ubuntu]
We can use it to open a TCP
In the use of Gearman do distributed processing, each machine needs to register a separate job as a feedback, in order to facilitate, Gearman::worker script register_function code, and then think of the use of their own IP address as job name.
So how do you get native IP as a func in a worker script?
The first approach, the simplest, calls the shell:
Copy Code code as follows:
$ip = ' ifconfig eth0|grep-oe ' ([0-9]{1,3}\.?) {4} ' |hea
