i almost forgot about hping2 and nemesis. nemesis doesn't listen, though,
but in combination with tcpdump (process the dump with perl or awk, for
example) you can construct a simple port scanner. hping2 will listen for
the response. ipsend can also be used.

small shell or perl wrappers around these should make what you want to do
easy.

hope that helps.
