NAME

       nwfsctrl - Perform server command

SYNOPSIS

       nwfsctrl [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -p ncpfs path ] -c | -o | -[f]d

       nwfsctrl [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -p ncpfs path ] server command

DESCRIPTION

       nwfsctrl performs command on server.

OPTIONS

       -h
	  With -h nwfsctrl prints a little help text.

       -S server
	  is the name of the server you want to use.

       -U user
	  user is the user name to use for login. To set the server's time, you need supervisor privileges.

       -P password
	  password  is	the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwfstime
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login. As you need supervisor privileges for  setting  the  date  and  time,  this
	  option is probably not used very often.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -o
	  Open bindery.

       -c
	  Close bindery.

       -d
	  Down fileserver. This command will complain if there are open files on server.

       -fd
	  Down fileserver, regardless of opened files.

       load module options...
	  Load module module with options options... on server. Program will complain if module is already loaded.

       unload module
	  Unload module module from server. Program will complain if module is not loaded.

       mount volume
	  Mount volume volume.

       dismount volume
	  Dismount volume volume. If there are open files on volume, server displays prompt on console. You must go to the server (or telnet/xcon-
	  sole) and hit Y or N to get beyond this point).

       set variable = value
	  Set server settable variable variable to value value.

       open bindery
	  Open bindery.

       close bindery
	  Close bindery.

       enable login
	  Enable login to file server.

       disable login
	  Disable login to file server.

       disable tts
	  Disable TTS. This probably does not work on Netware 4.11.

       enable tts
	  Enable TTS. This probably does not work on Netware 4.11.

BUGS

       Other commands are not written yet (volume, clear connection ...)
