Hello,
        I am trying to develope a programme, through which i can access two different Cisco Switch at the same time and open its port no 23, but when i execute this script it does not display any message and i press   "Crtl + c " to come back in Linux command promt.

#!/usr/bin/expect -f
set switch {192.168.0.3 192.168.0.4}
set running 0
log_user 0

foreach x $switch {
spawn telnet $x
expect -i $x "Username:"
send -i $x "name\r"
expect -i $x "Password:"
send -i $x "password\r"
expect -i ">"
send -i $x  "enable\r"
expect -i $x "Password:"
send -i $x "password\r"
expect -i $x "#"
send -i $x "conf t"
expect -i $x "#"
send -i $x "int fas 0/23\r"
expect -i $x "#"
send -i $x "no sh\r"
expect -i $x "#"
send -i $x "do wr"
expect -i $x "#"
send -i $x "do exit\r"
}

Thank You Advanced.

It's probably hanging up someehere in the send and expect sequence - probably a tiny error in your choreography.  And as you've not got any puts statements anywhere in your code, there's no output at all so you're not being given any clues!

As a first step, I would remove the
log_user 0
so that all the protocol exchanges will be echoed on the screen. That way' you'll see where it comes to a halt.


I just remove the log_user 0 and run it again but again it take almost 4 minut to execute but, port 23 is not configured at all , and display in that format ,
in linux this script after excution,

[mansoor@tech mansoor]$ ./mspawn
spawn telnet 192.168.0.9
spawn telnet 192.168.0.47
[mansoor@tech mansoor]$


Then your problem lies at the very beginning with the spawn ... it's not getting any login offer back so you're having a timeout at each and every stage.   Try running the telnet from a shell and see what's happening.


Hello Graham,

Sorry for delay, due to some reasons, any when i telnet from shell it work very well, but whenever i run this script spawn takes time, and dont implement any configuration on the switches.

.... and having now run it from telnet, look and see exactly what the difference are and that should lead you in the right direction ...
