script to connect to Xyplex Terminal Server

[simpson]

Hello all,

Looking for some help in incorporating some communications with our Xyplex terminal servers into my syscheck scripting. Really don't know where to begin when it comes to making a connection to a terminal server and executing commands remotely. Any help or direction as to where I can become more enlighted would be appreciated.

expect is your friend. It's a language for automating interactive applications.

You can use telnet to connect to terminal servers/ports. They can be configured one of two ways: an IP per port or one IP and multiple port numbers. To check your ports, you can either check one port at a time or telnet to the terminal server and run a command to check whether a connection is established or idle. The problem with expect is that you'll be required to create a file with "expected" parameters. Depending on what level you want to verify the connection, you may have to supply passwds. This sounds eerily close to something I created years ago. You woudn't happen to be from Nortel would you?

Thanks for the responces. I expected that I would have to use expect. (haha) But I was hoping for a different answer. I quess it is expect.

No, sorry I don't work for Nortel. I am fairly familiar with Terminal servers I was just hoping for some type of connection string I could incorporate.

Thanks again.

Expect/Tcl is easy to use.

Here's a sample toy script that takes a hidden password
entered by the user at init and plays cheey tricks
on the password entered.
Just an example to show how flexible expect/tcl can be.

#!/usr/bin/tclsh
package require Expect

#exp_internal 1
set prompt ".*@.*"

proc getpass {str} {
      stty -echo
      puts -nonewline stdout $str
      flush stdout
      set ans [gets stdin]
      stty echo
      return $ans
}


proc fakehash {string} {
set len [expr int(1 + rand() * [string length $string])]
set str [format %s h$len]
 
  if {[binary scan $string $str out] == 1} {  
      return $out
  } 
return $string
}

       set pass [getpass "\nPlease enter the password for your procedure: "]
       spawn -noecho /bin/sh

          expect {

                        -re "$prompt" {
                                       interact {
                                                -o
                                                 timeout 5 {
                                                 send_user "Onetime hash = [fakehash $pass]\n" ; send "\r\n" 
                                                 }
                                        }
                          }

                         eof {send_user "\n Id at $spawn_id, died unexpectedly..\n"}
                         timeout {send_user "\n $spawn_id timed out..closing.."}
                          
            }

Good luck.
