## sinetstat ##
.

An alternative to the standard __Linux netstat__ or __ss__ command.<br>
It can display all TCP/UDP network sockets including (hidden) IPv4-mapped addresses.

 

__Improvements to the original netstat command:__ <br>
 \- *explore IPv4 in IPv6 listening/established sockets (IPv4-mapped IPv6 addresses)*<br>
 \- *prints full output of command including its arguments*<br>
 \- *shows UID and PID of the command*<br>
 \- *shorten output by hiding repeated entries on reused (SO_REUSEPORT) ports*<br> 
 
  
  
For a full featured output the script needs root-privileges.  
.

This is a Python 2.x/3.x script.  
Maybe the shebang line needs to be adjusted, depending on the Python installation of your system.
