    Thats a good list to start out with, but if you really want to know the full list of ports, check out RFC 1700 for an exhaustive list of ports and the apps/services that use them. The RFC is a bit outdated, but still reasonably useful. lol, and as for the open ports comment, just about any open port is a danger really, because no program is perfect or completely secure, but that is besides the point. Also, the RFC is rather large, and contains more than just the port list, so don't open it and just hit print otherwise your going to have a huge pile of paper.

    .:Shrekkie:. - yup that's perhaps the best list I have found out there for port numbers assignment.

    Also, as Soggybottom pointed out on another thread, don't take those lists as the end all of what is running on those ports. Just about anything can be listening on any port, these are the lists of what SHOULD be running there. It's always a good idea to double check if in doubt.

    Give a man a match and he will be warm for a while, light him on fire and he will be warm for the rest of his life.
