Exception1: Unless you are fragmenting incoming data into chunks equal to
or smaller than the size of your static buffer less 1 byte for the NUL
character terminator. :)
Lemma1: Never assume anything about incoming data sizes, or formats.
Example: The SBM client being able to do the equivalent of "cd .." on the
root level of an NT share.
Lemma2: Always make sure when expecting data to time out if you do not
receive what you expect. Example: telnet to port 135 of unpatched NT
server 4.0, type 10 characters, hit ENTER and disconnect.
