Name
       syscript - dialogue for running system exercisers

Syntax
       syscript

Description
       The command presents a dialogue that lets you run any of the following system exercisers:

       cmx(8)	 Tests the terminal communications system

       dskx(8)	 Tests the disk drives

       fsx(8)	 Tests the file systems

       lpx(8)	 Tests the line printers

       memx(8)	 Tests memory

       mtx(8)	 Tests the magnetic tape drives

       netx(8)	 Tests the TCP/IP network system

       To execute the command, you must be logged in as the superuser, and your working directory must be the directory.

netx(8) 						      System Manager's Manual							   netx(8)

Name
       netx - TCP/IP net exerciser

Syntax
       /usr/field/netx [ -h ] [ -tn B ] [ -pm ] nodename

Description
       The  exerciser  sets  up a stream socket connection to the server in the TCP/IP internet domain. With connection made, the exerciser writes
       random data to the server; the server loops the data back to and the data is read and verified against the data written out.

       The exerciser runs in conjunction with the server.

       The exerciser by default will use the port number of the echo service in the file. Make sure that the TCP echo service is  enabled  in  the
       file  (no `#' in front of the service). The exerciser will run until or kill -15 pid is sent to the process.  The nodename is the remote or
       local system host name running the server.

Options
       The netx options are:

       -h	 Print the help message for the command.

       -tn	 Run time in minutes (n).  The default is to run until the process receives or kill -15 pid.

       -pm	 Specify port number to use in internet domain (m < 32768).  Note that this option is not used with  the  server,  so  you  should
		 never have to use this option.

Restrictions
       If  there  is  a need to run a system exerciser over an NFS link or on a diskless system, there are some restrictions.  For exercisers that
       need to write into a file system, such as the target file system must be writable by root.  Also the directory, in which any of	the  exer-
       cisers  are  executed,  must be writable by root because temporary files are written into the current directory.  These latter restrictions
       are sometimes difficult to overcome because often NFS file systems are mounted in a way that prevents root from writing into them.  Some of
       the restrictions may be overcome by copying the exerciser to another directory and then executing it.

Examples
       The following example exercises the TCP/IP network from the local host to node keel until a or kill -15 pid is received:
       % /usr/field/netx keel
       The following example exercises the TCP/IP network from the local host to node photon for 180 minutes in the background:
       % /usr/field/netx -t180 photon &
