       This  manual  page  was  written by Jesus Climent <jesus.climent@hispalinux.es>, for the Debian GNU/Linux
       system (but may be used by others).

                                                                                                     PCONSOLE(1)

pconsole  allows  you  to  connect  to  each  node  of your cluster simultaneously, and you can type your
       administrative commands in a specialized window that ´multiplies´ the input to each  of  the  connections
       you  have  opened.   pconsole  is  best  run  from within X Windows, although it is possible to employ it
       without X (in console mode) as well.

       You need to install pconsole on only 1 machine in  the  cluster,  this  would  usually  be  your  central
       administrative node.

       pconsole - parallel console shell for administering clusters.

pconsole  need  to  be executed with superuser permissions, and enters in interactive mode let you attach
       other devices so that all the commands sent to the console mode of pconsole are sent to the devices. This
       allows you to parallelize the execution of the same command in various machines at a time.

       pconsole has two working modes:

       commandmode
              From this mode pconsole can attach and dettach devices, list  the  attached  devices  at  a  time,
              connect  to  sending mode where you can send commands to the attached devices, and quit.  To enter
              in command mode, use CTRL-A from sending mode.

       sendingmode
              The mode where the commands sent to it are sent to the devices attached.  To enter this  mode  use
              CTRL-D or use the console command.
