Calling a file during telnet expect

Posted by mansoorx (mansoorx), 9 May 2007
Hello,
 
I would like to run a Multiple commends in a spawn telnet, my telnet device is a router;

when i telnet through the Expect to the router,

#!/usr/bin/expect -f
log_user 0
spawn telnet [lindex $argv 0]
expect "Username:"
send "mansoorx\r"
expect "Password:"
send "xxxxxx\r"
expect [lindex $argv 1]
send "enable\r"
expect "Password:"
send "yyyyyyy\r"
expect [lindex $argv 1]
send "conf t\r"
expect [lindex $argv 1]  

and  now i would like to call a file of multiple commands from  a linux server.

is it possible.

Thank you.

So the file of commands you want to run is on the machine on which you're running the expect script is it?   If so, you can open the file using standard Tcl commands and wrie a loop to send each of them, expecting the appropriate response, from your router.

If the Linux box in question IS the router, then you can kick the file of commands off by sending just what you would send from a normal telnet session in order to run the commands

And if the Linux box is a third system .... I guess you could use another spawned connection within expect to grab it, then proceed with it as if it was on your local (expect host) machine.
