When I add option interfaces = eth0 in smb.conf file I can search masterbrowsers on eth0 interface: # nmblookup -M -- - It works perfect. When I change eth0 to eth1 it works fine too. But it is impossible to search masterbrowsers on both interfaces at the same time. interfaces = eth* or 'eth0 eth1' does not helped.
Changing component, as this is not the "net" command.
