Re: Identify rogue adsl modems routers in the network

[pinowudi <pinowudi () gmail com>]

external detect - wardial

internal detect - ping sweep every node and record the MAC.  Might have 
to get segment access to each switch or forward the arp tables from each 
switch to central.  Run the MACs against the corporate gold standard for 
standard/approved equipment types.  This assumes the corp uses a 
standard supplier for routers and workstations/servers.  ID the 
outliers.  May find modems, wifi rogues, personal laptops, etc.
