Question expect question

I am trying to write a script that telnets out to multiple ip's, runs some commands exits and the telnets to the next ip. I wrote the following script and it works great until the program hits a nonresponsive ip.
I would like this to recognize the ip is bad and move on in the foreach loop. How do I do that?

Any ideas or suggestions are much appreciated.

Here is my script:

#!/opt/bsmext/bin/expect


spawn ssh -l username ip

expect ":"

send "password\r"

expect "$"

foreach ip $argv {
for {set ip 1} {$ip <=120} {incr ip 1} {

expect "$"

send "ssh -l default 10.x.xxx.$ip\r"

expect "password:"


send "xxxxx\r"

expect ">"

send "en\r"

expect "#"

send "xxxxxxxx\r"

expect "#"

send "xxxxxxxx \r"

expect "#"

send "xxxxxxx \r"

expect "#"

send "exit \r"

expect ">"

send "exit \r"

sleep 5

}
}

You can use "set timeout 20" where 20 is the interval in seconds to wait.

Thanks I tried the timeout but still didnt work. I may have to mess around with

expect {
-timeout 60
"password: {continue}
"$" {commands to go to next on in the list /loop}

timeout {#commands to go to next one in the list/ loop}
}

I been trying to tweak this out above but cant get it quite right.

Try setting it globally, as in :
Code:
#!/path/to/expect

set timeout 30

then the code

I found my problem. I found all the dead ip's and included an if statement. For instance below if I knew 10.1.1.12 was a dead ip I would write:


foreach ip $argv {
for {set ip 1} {$ip <=120} {incr ip 1} {

if {$ip ==12} {

continue

}

Thank you to all that replied.
