Telnet from shell script , further need to logout if log in not authenticate
Using unix shell script file I need to telnet to a IP further send a command to the telnet IP and get the response to a file with out using "expect" utility and I have achieved this by below command.
But now if the user "name" or "password" is wrong we get "Failed login" when we try to telnet. I need to catch this for the first attempt itself and exit the telnet session immediately.
Code:
(sleep 3; echo admin; sleep 3; echo mypass; ... )|telnet 192.168.1.1 | grep "Failed" | " Need To Write Code here I guess To Exit if FAILED" | >>$telnet_result
Or else is their any other way or method so that I can get the "Failed Login" and exit the telenet session?. Please suggest.
Hi,

Thanks in advance

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.
