using expect script to execute command on palo alto firewall

L0 Member

Hello, I'm using the code below to get ha state on my palo alto firewall but the output is not ok, there is a loop one the command and extra output caracters.
I'm using it with ansible in this scenario: ansible connect to a jumthost that execute this expect script on the palo alto device

#!/usr/bin/expect
set send_human {.1 .3 1 .05 2}
set network_expect_instructions_prompt "@.*>"
set network_expect_instructions_exitcode_wrong_password "2"
set network_expect_instructions_time_to_sleep "3"
set network_expect_instructions_timeout "30"
set timeout "30"
set network_target_pass "$env(NETWORK_TARGET_PASS)"

# commands communes de connectivités
spawn ssh -o StrictHostKeyChecking=no user@paloalto

expect {
-re "Password:" {
if { 0==1 } { puts "prompt ok!!"}
send -h "$network_target_pass\r"
}
timeout {
puts "no password: prompt"
set exit_code 3
if { $exit_code!=0 } { exit $exit_code }
}

}

# commandes de l'instructions
puts "EXPECT_BEGIN\r"

expect {
-re "$network_expect_instructions_prompt" {
if { 0==1 } { puts "prompt ok!!"}
send -h "show high-availability state\r"
}
timeout {
puts "prompt $network_expect_instructions_prompt not found."
set exit_code 3
if { $exit_code!=0 } { exit $exit_code }
}

}
expect {
-re "$network_expect_instructions_prompt" {
if { 0==1 } { puts "prompt ok!!"}
send -h "exit\r"
}
timeout {
puts "prompt $network_expect_instructions_prompt not found."
set exit_code 3
if { $exit_code!=0 } { exit $exit_code }
}

}
puts "EXPECT_END\r"


Here is the output

user@paloalto> show high-availability state\r
