@ Command

Command

@ -- Request / answer password challenge

Synopsis

@ [string]

Description

In order to gain access to sensitive commands, remote sysops must first complete a password challenge. Firstly, the remote sysop enters "@" alone, and the system replies with a matrix consisting of 5 lines of 5 numbers thus:

	4 1 6 3 7
	3 5 2 6 3
	7 1 9 2 4
	2 7 1 4 6
	3 5 2 6 1

The remote sysop must then choose ONE of the lines, and send the "@" command again, followed by the 5 characters from the password string which correspond to the 5 numbers on the chosen line. There must be a space after the "@" but no spaces between the characters.

If the challenge is correctly answered, the system replies with "Ok", and the user has remote sysop status.

Limitations

If the user does not have a password registered in PASSWORD.SYS, the response to this command will be "Bad command".

Note

Console sysops already have full access and don't need to use this command.
