Written by Neill Miller (neillm@thecodefactory.org) This simple port util program takes an ip address and a list of ports on the command line and checks to see if if each of the ports is active. If the port is not responding, a command is issued to restart the service via ssh. All results are also logged. --------------------------------------------- How to compile (tested on GNU/Linux only): --------------------------------------------- gcc port_util.c -o port_util --------------------------------------------- How to run: --------------------------------------------- ./port_util Usage: ./port_util -i IP-ADDRESS -p PORT1,PORT2,PORTN ./port_util -i 192.168.1.5 -p 22,80,443,9999 --------------------------------------------- Example output log: --------------------------------------------- ------------------------------------------------- Starting system scan at Fri Nov 14 13:00:56 2014 ------------------------------------------------- Checking port 22 on 192.168.1.5 Connection success, service is active!
