CTLUSER(8) System Manager's Manual CTLUSER(8) NAME
ctluser - control lusers SYNOPSIS
ctluser [ -h ] [ -m ] command [ argument... ] DESCRIPTION
Ctluser sends a message to the control channel of a given luser(8) This command can only be run by the sysadmin(1) In the normal mode of behavior, the message is sent to the luser's brain, which then performs the requested action and sends back a reply with a text message and the exit code for ctluser. If the luser's brain successfully performed the command, ctluser will exit with a sta- tus of zero and print the reply on standard output. The ``-m'' flag is used to display an MPEG of the results of the given command on the console of the sysadmin(1) Note that this requires the sysadmin(1) to be running an X server. To see a command summary, use the ``-h'' flag. If a command is included when ctluser is invoked with the ``-h'' flag, then only the usage for that command will be given. The complete list of commands follows. Note that all commands have a fixed number of arguments. If a parameter can be an empty string, then it is necessary to specify it as two adjacent quotes, like "". addhist <entry> Add an entry to the luser's employment record. allow reason Allow a luser to use the computer system again. The reason must be the same text given with an earlier ``reject'' command. Note that this command is currently not implemented. begin name Begin a new luser(1) with the given file. Note that this command is currently not implemented. cancel pid Causes a process of a luser to be killed changegroup group Changes a luser from their current workgroup to the one specified. checkfile Forces a user to return to a paper based system drop Causes a large mass to drop onto the luser from a great height. flushlogs Destorys all logs of the actions done by the sysadmin(1) to the luser. go reason The luser is fired for the given reason. hangup Makes the luser hang themselves mode Displays the operating mode of the luser newgroup group Causes a luser to make their own newgroup up pause thought Makes the luser pause for the given thought. Note that this may cause some lusers to crash shutdown reason Makes the luser shutdown. This is essentially the same as killing them signal sig Sends the given signal to the luser throttle reason Causes the luser to throttle themselves trace item flag Gives the sysadmin(1) information on what the luser is doing. BUGS
Ctluser sometimes has the effect of lusers complaining the to management. The use of bosskill(8) maybe required at this point. HISTORY
