You can nmap the ip's you think is stolen. You can guess the operating system using the -O parameter to nmap. Other tools give you more data. > How can I find out, that IP is being doubled? You cand find out if an IP is being doubled using arping. If you do arping -b, all the machines using that IP will respond to the broadcast arp, thus giving you the posibility to immediatly spot a conflict (there will be two machines responding). > -- > Thanks for all replies :P > > Lenthir > _______________________________________________ > LARTC mailing list > LARTC@xxxxxxxxxxxxxxx > http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc > _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
