Question KORN Shell - Spawn new shell with commands
I want to be able to run a script on one server, that will spawn another shell which runs some commands on another server..

I have seen some code that may help - but I cant get it working as below:


spawn /usr/bin/ksh
send "telnet x <port_no>\r"
expect "Enter command: "
send "LOGIN:x:x; \r"
expect "Enter command:"
send "LOGOUT; \r"
close

but this errors - I may be missing code etc, I honestly dont know. Can anyone help me? Or is there another way to do this?
I dont want to execute a script on the other server, I want to log on to it and type some commands, get the response and log off... Please note I log on to server on a specific port - this is not telnet.

Any help would be appreciated.

gems-server

GEMS-SERVER(1)							gems documentation						    GEMS-SERVER(1)

NAME

       gems-server - Transmit a shell session in real time.

SYNOPSIS

       gems-server [-ip ip] [-port p] [-maxconn n] [-wait m] [-log dest] [-noscript] [-script_bin script]

       gems-server -h | -v

DESCRIPTION

       Transmits a shell session to be shown in real time in various different computers or terminals.

       gems-server  transmits data in real time to clients via a network connection. Each one of these clients must run the gems-client(1) program
       to establish connection and receive the transmitted data. Clients can connect and disconnect at any given time, but  of	course	they  will
       only receive the data that is transmitted while they are connected (just like a radio transmission/reception system).

       The  gems  system is normally used to transmit a console session and show it in various computers at the same time, but it is also possible
       to transmit any other kind of data.

OPTIONS

       -ip    IP address where connections will be accepted.

       -port  TCP port. Default: 6666.

       -maxconn
	      Do not accept more than n simultaneous clients. Default: 25.

       -wait  Wait until m clients are connected before starting the transmission. This is useful to ensure that the first m clients will  receive
	      all data transmitted. The default behavior is to start transmission immediately, without waiting for client connections.

       -log   By  default,  the server does not write log messages. This option configures the destination of logs. The dest argument can be `sys-
	      log' (to log through syslogd(8)), `stderr' (to log through standard error output), or it can be an arbitrary filename (log  messages
	      will be appended to the file, if it exists).

       -noscript
	      By  default,  the  server  executes the script(1) program to take terminal data and transmit it. When this option is used the server
	      will not run script, and data will be read form standard input.

       -script_bin
	      Specifies the location of the script(1).	program. Default: /usr/bin/script.

       -h     Show a short help message.

       -v     Show version information.

FILES

       /var/lock/gems-server.PORT
	      Lock file.  gems-server creates this file on initialization and deletes it on exit. PORT is replaced by the TCP  port  used.   gems-
	      server will not run if this file is already present in the system.
