THE MOST FREQUENTLY USED SysOp & User COMMANDS:
The Command Interpreter within the node firmware supports several commands including; CONNECT, TALK, MHeard,
ROUTES, NODES, USERS, PARMS, INFO, RESET, and SYSOP. Here are a few of the more commonly user level
commands.
The CONNECT command enables a user to request a circuit to a distant node, a downlink to a user station, or a direct
connection to the local host terminal (if there is one) attached to the node.
The NODES command permits a user to obtain a list of other nodes for which the local node has routing information, and
to examine the routing details to any particular node. It also allows an authorized SysOp to add, delete, or change routing
table entries manually.
The USERS command displays a summary of the current activity at the node, including information about active uplinks,
downlinks, circuits, patch cords, and users in command mode.
The PARMS command displays a series of numeric node parameters, and allows an authorized sysop or network manager
to change the values of these parameters. The INFO command displays information about the node which has been
uploaded by the node sysop or network manager. TheNET X1 allows a sysop to change the information remotely. To
delete current INFO from the node, the sysop (while in the sysop command mode) may enter an "I" followed by an asterisk
i.e.; I *. A space is placed between the I and the asterisk.
The MHeard command enables the user to see a list of stations recently HEARD by the node. In addition, it the X1 node
is equipped with the Suffolk Data Group (MFJ model MFJ-52) DEV add-on PC board, the MHeard list will reveal the users
deviation, signal strength, voltage at the site, and the temperature at the site.
The RESET command permits a sysop to reset (warm-start) the node remotely. To place the node firmware at DEFAULT,
perform a RESET<space> *(asterisk).
Simply stated: RESET *
Another way to perform the reset is to send the node:RESET <space> RESET <Enter>
Stated: RESET RESET
SYSOP VALIDATION:
Authorized sysops can make manual updates to routing table entries with the NODES command, modify various node
parameters with the INFO, MODE, PARAMS, and other node commands or do full "cold-starts" and "warm-start" using
the RESET command.
To do these things remotely, a sysop must first validate his credentials by means of the SYSOP password, otherwise, the
remote update commands are locked out.
A password string up to 80 characters long is entered into the node by an on-site operator via a local terminal. The
password string cannot be changed remotely. When a remote operator enters the SYSOP command, the node replies with a
list of five random numbers. The sysop must then enter the five characters that correspond to the numbered character
positions in order to have sysop privileges. The section that follows will explain how the sysop deals with the password.
