have a look at the nmap manpage:


I did... but...

1214/tcp   filtered    kazaa
1503/tcp   filtered    imtc-mcs
1720/tcp   filtered    h323hostcall
1863/tcp   filtered    msnp

which happen to be the four ports we were experimenting with. since
it;'s closed, no problem but it struck me that it was filtered.

and next run it will show the actual state. it just sometimes happen.
that's the weird part of it....


e.g. the output is not consistent.
