I donßt know what "whod" is, but I´ve stopped this using the following commands in my
/etc/isdn/device.ippp0

#At the end of the Start section
#Output Firewall, dont allow connection to Port 137-139 and 513 with UDP
#TCP is allowed.
ipfwadm -O -p accept
ipfwadm -O -a deny -P udp -S 0.0.0.0/0 137:139
ipfwadm -O -a deny -P udp -S 0.0.0.0/0 513

#in the Stop section
#Delete Firewall Rules
ipfwadm -O -f

Depend on your kernel version you may use ipchains or then ipwadm/ipchains wrapper.
Ipchains ist the newer method of kernel 2.2.x

Good luck,
