I don't have an example handy, but as I recall the working construct is based on this form of code fragment:
I once wrote a script that automatically 'telnetted' into hundreds of Cisco routers and changed the passwords when an employee was terminated. This was about 7 years ago and my memory on the actual code is foggy. I do remember that we used KSH and used a contruct like the one above.
I suggest you get out your best shell programming book and use the construct above in the correct syntax. For example, I don't recall if you use a pipe "|" or perhaps a "<" redirection tag to send the telnet output to the while logic block. You would have to get this from studying the construct and perhaps some simple trial and error. Sorry not to remember more.

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.
Thanks,

Hi all,
I would like to write a ad hoc shell script that would allow me to do some telnet tests to multiple IP's and ports at the same time . So, I want to determine which one is successful and which one fails. So, basically I would like the shell to spawn the telnet test and to break out of... (3 Replies)

I wrote a script for doing telnet.However the requirement got changed and now I have to write a telnet script that will

rxtelnet
RXTELNET(1) BSD General Commands Manual RXTELNET(1)NAME
rxtelnet -- start a telnet and forward X-connections.
SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port]
DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be
able to connect securely to your X server. If port is given, that port will be used instead of the default.
If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding.
The supported options are:
-l Log in on the remote host as user username.
-k Disables keep-alives.
-t Send telnet_args as arguments to telnet.
-x Send xterm_args as arguments to xterm.
-X Send kx_args as arguments to kx.
-w Use term_emulator instead of xterm.
-b Use telnet_program instead of telnet.
-n Do not start any terminal emulator.
-v Be verbose.
EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following.
1. On foo: rxtelnet bar
2. You will get a new window with a telnet to bar. In this window you will be able to start X clients.
