The sysop (System Operator) is the administrator that runs the BBS, and they have unlimited access and control over their instance of Synchronet and its users. When networked with other systems (e.g., DOVE-Net, FidoNet, inter-BBS chat), they are often considered responsible for any traffic originating from their system, including misconfigurations and any of their users' poor behavior.

There is usually one sysop per BBS, though Synchronet can be configured for multiple sysops (sometimes called co-sysops). In Synchronet, any user with a security level at or above 90 is considered a sysop.

Depending on the “Require Sys Pass During Login” in SCFG System Configuration under Toggle Options, the sysop will either be required to enter the system password at login or when performing a sysop-level function. Synchronet will prompt with SY: when asking for the system password.

Multiple Sysops / Co-Sysops

Multiple levels of sysop access (90-99) can be used to restrict some areas (i.e., message groups, sub-boards, file libraries, etc.) by setting the minimum required level of that area higher than the sysop's security level.

Any user with a security level at or above 90 can perform sysop functions, including ;SHELL access with the same OS permissions as the OS user that the BBS runs as.

Using the in-BBS ;UEDIT user editor, a sysop with security level at or above 90 cannot edit a sysop with a higher security level. ;SHELL can potentially give access to the useredit application that allows full user editing privileges, however.

:!: Users with sysop access can cause damage to the BBS, as well as compromise the underlying operating system. Give out sysop-level access with caution.

Sysop Commands

A menu of the available commands can be viewed with the '!' command from the main or transfer sections with the Synchronet Classic command shell. Additional sysop commands are available in many other sections of the BBS and are displayed after the normal menu with the '?' command. All sysop commands from the main or transfer sections of the Synchronet Classic command shell begin with a semicolon (';') character, end with CR (ENTER), and some have optional parameters (shown in square brackets). Users with certain exemptions can use some of these commands and have access to the menus via the '!' command using the Synchronet Classic command shell.

Note: The Baja source code file for these commands is: exec/str_cmds.src


  • All commands are preceded by a ;
  • <> required parameter
  • [] optional parameter
  • () required exemption

Commands for All Users

Command Name Description
HELP Display available string commands List the string commands available to the user along with short descriptions.
FIND [word] Find a message area or file area Returns a list of message areas or file areas matching the search term. Search [word] can be part of a word, a full word, or a phrase. The command will search message areas if run from the main menu, or will search file areas if run from the file menu.
MSGS Redisplay messages Redisplay instant messages (notifications and telegrams) that the user previously received.
PLAN Edit .plan file Edits or deletes your .plan file (displayed when somebody Fingers you).
POFF Pager off Toggles if other users can page you during this session for a multinode chat.

User & Mail Management

Command Name Description
UEDIT [user number or name] User editor Starts the User Edit function, allowing the sysop to edit or delete/restore users. If a [user] is specified it will be the current user when User Edit starts. FIXME add link when user editor page is created
BULKMAIL Send mass mail Sends an email to all users that match a specified Access Requirements String (“ARS”).
CHUSER Change to another user Allows the sysop to temporarily change to another user account. If changing to an account with a higher level, the password of that user must be given. Changing to a user of non-sysop status automatically enables Temp Sysop mode so that the sysop can change back to their own account before logging off (a suggested action).
MAIL Read all mail Read all the email in the mail base, regardless of recipient.

Node Control

Command Name Description
NODE [parameters] Node utility Executes node utility with the passed parameters.
DOWN [#] Down node Toggles the down status of a node. When a node has a down status (noted by the [D] flag on the node status line) it will be shut down after the user logs off, or immediately if a user is not online. If a node [#] is not specified, the current node will be shut down.

To put an “Offline” node back to a “Waiting for Connection” status, use ;NODE STATUS=0 [node #].
INTR [#] Interrupt node Disconnect a user as soon as it is safe to do so, displaying a “closed for maintenance” message. The current interrupt status of a node is reflected by an [I] in the node listings. If a node [#] is not specified, the current node will be interrupted.

If the user is currently executing an external program (including editors and transfer protocols), they will be disconnected as soon as control returns to Synchronet.
LOCK [#] Lock node Prevent users from logging into a node, giving a “down for maintenance” message. A locked node will have an (L) in the node listings. If a node [#] is not specified, the current node will be locked.

Sysops and users with the L exemption can still log in.
RERUN [#] Rerun node Toggles the rerun status of a node (noted by an [R] in the node listing), reloading the configuration before the next login. If individual nodes have a rerun status, that node's configuration will be reloaded just before the next user logs in. If all nodes have a rerun status, the configuration for the nodes will be reloaded when all users have logged off.

Note: Saving a configuration change in SCFG will set a rerun status on all nodes.
SPY [#] Spy on a node Allows the sysop to remotely monitor or control another node.

Logging & Stats

Command Name Description
ERR Critical error log View the error log and optionally delete it, as well as optionally clearing all nodes' error counters.
LOG Today's log View today's detailed node log file.
YLOG Yesterday's log View yesterday's detailed node log file.
NLOG [#] Node statistics log View the historical, daily statistics for a single node. Statistics for the current node will be shown unless a node [#] is specified.
NS [#] Node statistics Today's statistics for single node. The node [#] will be prompted for if it is not provided.
SLOG System statistics log View the historical, daily statistics for the system (sum of all nodes).
SS System statistics Today's combined statistics for all nodes.

Node & Sysop Display

Command Name Description
ANON Toggle anonymous mode Makes the current node anonymous, where the node is listed normally but the user is displayed as “Unknown User.” To a sysop, an anonymous node appears normally with the addition of an [A] in the node information line.

Sysops and users with the Q exemption have access to this command.
AVAIL Toggle sysop chat availability Changes the ability for users to page the sysop for a private chat, visible to them in the chat module.

This setting can be overridden by users with a C exemption or by the SCFG System ConfigSysop Chat Override” Advanced Option.
QUIET Quiet mode Make the current node appear to be “Waiting for call” to other users. To a sysop, a quiet node appears normally with the addition of a [Q] in the node information line.

Sysops and users with the Q exemption have access to this command.

OS & Files

:!: For any commands where a path is requested, the current working directory is ctrl/

Command Name Description
=) EXEC [command] FIXME Execute a command with I/O redirected FIXME Execute internal DOS commands (DIR, TYPE, etc.) by prepending “command /c” to your command line.
