muzete mi nekdo vysvetlit, proč nmblookup funguje jen jednim smerem? 
Pokud zadam IP tak nenajde NETBIOS jmeno ale obracene funguje bez problemu.
S parametrem -A [IP] to také funguje



[root at test63 ~/script]# nmblookup -T 192.168.0.92

pri googleni jsem ale narazil na bombasticky programek nbtscan 
(/usr/ports/net-mgmt/nbtscan), kde zadate rozsah site a on na vas 
vybafne IP, nazev stroje,uzivatele a MAC. Viz nize
