COLLIDE(1) FNORDADEL BBS SOFTWARE COLLIDE(1)
NAME
collide.tos - check for user log hash table collisions
SYNOPSIS
collide
DESCRIPTION
Fnordadel uses a "hash table" for speedy lookup of names
during login time. A hash function essentially turns a
string (say, a user name) into a (hopefully unique) integer,
which can then be used to index into an array of data (say,
user log entries). This saves time searching the array.
Unfortunately, it can happen that two totally different
names will hash to the same integer value. If someone tries
to login using a name which hashes to the same value as an
existing name, Fnordadel will report that "We already have a
<name>".
Collide checks to see if supplied user names "collide" with
names currently in the user log. Simply type a name at the
"name>" prompt, and collide will tell you which name, if
any, the given name collides with. To quit the program, hit
a <CR> at the name prompt.
Collide must be run from the directory containing
ctdltabl.sys.
OPTIONS
None.
NOTES
We hope to do away with the need for this program, someday.
Until then, tough doughnuts. (-:
