UNIX for Dummies Questions & Answers

Hi

I'm writing a script which calls an expect script to retrieve configuration files for network devices. I want to avoid using TFTP to transfer the configs if possible and so I'm redirecting the screen output to a text file.

This is the expect script:

#!/usr/local/bin/expect

set HOSTNAME [lindex $argv 0]
set USERNAME [lindex $argv 1]
set PASSWORD [lindex $argv 2]

set timeout 10

spawn /usr/local/bin/ssh -1 $USERNAME@$HOSTNAME
expect "word:"
send "$PASSWORD\r"
expect "#"
send "terminal length 0\r"
expect "#"
sleep 1
log_file /{$LOGFILEPATH}/$HOSTNAME-running.txt
send "show running-config\r"
expect "#"
sleep 1
log_file
send "logout\r"

exit 0


It works really well for most devices, so I'm not too hung up on the exact syntax of the script, but I'm having real problems with a couple of devices. The only thing that these problem devices seem to have in common is that the configs are bigger than usual. What happens is that around 85% of the config gets output and then the script just halts and won't go any further.

I've played around with the timeouts and the sleep commands and it seems to make no difference at all.

I've run it in debug mode and can't see any problems other than the fact that it just stops 85% the way through the config output. There are no # characters or anything else in the configs that could trigger a premature send either.

I thought maybe the expect buffer wasn't big enough but all I've read on the internet suggests that the buffer shouldn't be a problem. I'm pretty stumped as to why it just halts. As I said it works fine on most other devices.

Any ideas anyone?

Thanks.

OK. Nobody seems to know the answer to this one

Anybody know any other method of doing it with an expect script apart from TFTP?

Hi there,

I have downloaded expect on my AIX 5.3
uncompress expect.tar.Z
tar -xvf expect.tar

Now I have the directory /usr/local/expect-5.43

I try to run the

autoexpect telnet 10.0.10.17

from the /usr/local/expect-5.43/example/ directory and it says

and it says ksh: autoexpect: not found.

Any Ideas?
