IP scan

Postby citro » Mon Mar 18, 2013 9:56 am

hi, if it is possible with php web interface scan active local network ip addresses? For example in LAN are 20 pc's. Two of them are turned on and their addresses are 192.168.10.10 and 192.168.10.16. If I enter ip range from 192.168.10.1 to 192.168.10.20 php returns these two active ip adresses (192.168.10.10 and 192.168.10.16).
Perhaps someone has some example?

One way I think is - use exec() in php to run a "ping" for a particular ip and parse the output to decide if that ip is present. So, for a range you have to loop through all the addresses in the entire range.
