linux - How test SSH connectivity with expect script -

i have linux red-hat machine - version 5.x

i want create expect script verify if ssh login remote machine successfully

my test password prompt on remote login ( not want enter password )

its test ssh connectivity

what created until following script

so if password prompt script need return 0

if not script need return 1

the problem script - script return 0 ssh login failed ( no password prompt )

 #!/usr/bin/expect    set login      [lindex $argv 0]  set password   [lindex $argv 1]  set ip         [lindex $argv 2]      set timeout 10  spawn ssh -o stricthostkeychecking=no $login@$ip  expect -re "(password:|word:)"  exit 0  expect {      timeout {error "incorrect password"; exit 1}  eof  } 

please advice how update script ?

you have enclose condition in 1 expect as,

set timeout 10 spawn ssh -o stricthostkeychecking=no $login@$ip expect {     timeout {puts "timeout happened";exit 0}     eof {puts "eof received"; exit 0}     -nocase "password:" {puts "ssh connection alive host $ip"; exit 1} }
