I work in a dynamic wireless environment where clients are constantly moving on/off the network.
Is is possible to setup Network Scanner such that (after the initial scan) it constantly has a single thread searching the network for new nodes and removing those that are no longer available?
I think that you have to create a script that will do a scan every 5 minutes, then put the result in a file, compare the files for MAC and/or IP change/remove to create a real network node list.
this is not the goal of this great tool. Much more i don't know any other commercial products to do it easily, using HPOV, Spectrum, Zabbix, Nagios, etc.
Try using OCS Inventory : http://sourceforge.net/projects/ocsinventory
There's no interval. Once the scanner finishes the current scan and activates the live display, it pings every host from the starting to ending address in a loop in one thread. In pseudo code this can be represented as:
while (not Terminated) do
if (FAddressTo >= FAddressFrom) then
for Addr:=FAddressFrom to FAddressTo do
<run a separate thread to (re)scan address Addr>
<and wait until it is complete>
