Hi:
I am interested in what TCP/UDP port numbers people are using. Largely the
port numbers above port #255. I am especially interested in protocols
which people are using, which may result in significant amounts of traffic
(e.g., X Window based stuff). I compiled a list of port numbers out of a
couple of Unix BSD /etc/services files as well as a new port number list
from Jon Postel. If you have applications for which you use specific port
numbers not in this list and which is of more than strictly local use, I
would appreciate a note.
I would like to point out that this is a request just out of curiosity. It
should not be misread as having anything to do with trying to get any kind of
official (or unofficial) blessing of picking numbers, especially above the
"Well Known" port numbers.
