Displaying All Active Internet Connections In Linux

Friends it is  necessary to display what Internet connections are active on your Linux machine. For example, seeing the Apache service is actively running or not, and if running what network ports it's listening to. To do this run the below netstat command in the command line.

netstat -natp

If you have root privileges running the above command will give an output similar to the below example.

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:2208 0.0.0.0:* LISTEN 16271/hpiod

How can I Renew Or Release An IP In Linux?

If you love to work in Linux then this commands will really help you!!!!!!!!!!!!!!!!!!!!!

Coming from a Microsoft operating system to Linux you may be surprised to see there is not an option for ifconfig to release and renew an IP address. Below are two different methods of how this can be done at the command line.

ifconfig eth0 down:-

Running the above command would take the eth0 interface (the first network card) down. Which is the same as releasing the IP address from that network card.

ifconfig eth0 up:-

After the interface is taken down, typing in the above command would bring that interface back up.

      Thanking you Friends..........

Unix and Linux users:-

Changing the prompt in Unix and Linux varies depending on what shell you are using.

If you are using the C Shell, type:

set prompt="`hostname`>"

Displays the hostname in the prompt, similar to the below prompt:
Computer>

set prompt="`pwd`>"

Displays the working directory with the prompt:
