Awatmath.1588 net.lan utcsrgv!utzoo!decvax!watmath!jcwinterton Mon Jan 25 16:52:48 1982 Care and feeding of local area networks with a public user community. The publication in this newsgroup of the XYZZY command for the Sytek Localnet 20 product has been most counterproductive at this site. We are a large computer science school with the result that most of the students here are in the hacker class (at least after the first term). Undocumented testing procedures should remain so if at all possible, since anyone with access to a computer will try anything they can think of or find out. While this has only been a nuisance so far, the increasing number of connections to our net will increase our vulnerability to such things. (It appears that someone used the xyzzy procedure on our Localnet box that we use for uucp originating calls, and thereby hung it. I did a reset and tried to disable the command, and I hope it works. Anyway, this is a plea to keep such sensitive and possibly destructive stuff out of the public network.
