Reserved? Ports don't really get reserved so much as sit there and get taken on a 'first come, first served' basis.

Code:

netstat -tuanpl|egrep 'sendmail|postfix|smbd|nmbd'

now that's fine if the program is actually up and running and actually listening, but if the program hasn't started yet, you might be better grepping /etc/services. Now that only gives you the 'standard' port for the service, and you might have moved a service from the standard port, although the likelihood is that if you've moved it, you'd know. Probably.
