This is my expect script to telnet. Sometimes it works and sometimes
it fail.
Why and how to fix it?
set timeout -1
exp_internal 1
set res [spawn telnet $server]
expect "login:" { send "$user\r" }
expect "Password:" { send "$pass\r" }
expect {
"Last login" {
puts "..Connected ! "
sleep 0.5
}
"Login failed" {
puts "**FAILED** to TELNET to $server using ($user,$pass) "
exit
}
}
When the script fails, the error message is:
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
