Using expect script to automate building firewall templates in Panorama

Hi Community,

I have been struggling with this for weeks, and have tried various means, including setting the Panorama CLI parameters. However, I always get random results, which ends up either the cmdline was entered prematurely or truncated. A support ticket was logged but proved to less than helpful, as the answer given was to lessen the number of lines in the text file. The script will read in a text file with the commandlines to be run. I have use the similar script and run against SRX, and i do not encountered any issue with such. Please help.

Contents of my expect script:

#!/usr/bin/expect -f
# Set up various other variables here ($user, $password)
set force_conservative 0

log_file -noappend sendlog.log

if {$force_conservative} {
set send_slow {1 1}
proc send {ignore arg} {
exp_send -s -- $arg
}
}

set timeout 60
spawn $env(SHELL)
match_max 100000

set user [lindex $argv 0]
set password [lindex $argv 1]
set host [lindex $argv 2]
set exec [lindex $argv 3]
set exp_internal 1

# Iterate over the cmdline
proc sendcmds {PA_CMD} {
send -- "$PA_CMD\r"
expect -exact "# "
}

# Get the commands to run, one per line
spawn ssh $user@$host
expect -exact "Password: "
send -- "$password\r"
expect -exact "> "
send -- "set cli terminal width 200\r"
expect -exact "> "
send -- "set cli terminal type xterm\r"
expect -exact "> "
send -- "configure\r"
expect -exact "# "

set fr [open $exec r]
while {[gets $fr line] != -1} {
sendcmds $line
sleep 1
}
close $fr

# Tidy up
expect -exact "# "
send -- "exit\r"
expect -exact "> "
send -- "exit\r"
close

Hi Benson,

can you share a sample usage that you attempted? Where does it break, what output do you get, how far does it work?

Regards

Luciano

Hi Luciano,

Thanks, i have managed to resolve the issue, there is a scripting mode in panorama which i need to turn it on. After I have done that, everything plays out nice.

Rgrds,

Benson
