I needed a function to ping many computers, and get the results of the pings in an array so to manage it easily in a script. Searching in the forum I found some interesting sw with a nice graphical interface, but not a generic function that simply return an array. a very powerful pinger I found is >nPing by Manadar, but it is designed as a command line tool, so I decided to use the entire engine of nPing adapting it a bit, so that it can be used as an udf. This code is a first attempt (beta) and it can be used to: Ping all computers (IP addresses) belonging to the (local) LAN just call the _nPing() without any parameter Ping a predefined list of IP just pass the list of host (IP or hastnames) to the function in an 1D zero based array or in a 2D array indicating the column containing the addresses Ping all computers (IP addresses) of a remote LAN just pass an IP of that lan and his subnet mask Ping range of computers (IP addresses) just pass a string rappresenting the range of IP to ping (as accepted by the nPing program by Manadar), for example: 192.168.0.0-1 will ping these addresses: 192.168.0.0 and 192.168.0.1 192.168.20.* will ping everything in the range from 192.168.20.1 to 192.168.20.255 192.168.0-1.1-254 will ping everything in the range from 192.168.0.1 to 192.168.1.254 I have not done extensive testing on it, so I would be grateful if someone that tries it, can report any error thanks EDIT: After some testing, I have seen that sometime some IP are reported as dead, while are alive instead. This occurs when a device is not so fast to answer to the ping, and so it's marked as dead while instead is only too slow to answer to the ping. I came to the conclusion that for a more accurate result about the not responding devices, is better to use a $timeout parameter of 4000 ms as default value in the _MSPing() function (the same default timeout value as in the standard ping command) So I have "calibrated" the multiping.au3 by modifying the line 349 and incrementing the value of the $Timeout variable from 100 ms to 4000 ms. This should be a better choice for a general purpose utilization that gives more stable and accurate results about the not responding devices. This should not slow down the overall performances, but will only give some more time to respond to the slower devices.
