Authentification is not a word

Whether one is referring to...

authentication - the validation of credentials (i.e., "Yes, you are who you claim to be")
authorization - the validation of whether access should be granted based on that identity (based on role, group membership, policy, ACL, etc.) (i.e., "Yes, that user is allowed to access that resource")

...the word "authentiFIcation" never comes into play... nor authentify, authentificated, etc.

Identification / identify is a valid word, mind you.

Just saying...

Simple expect ssh example

This expect script would be called from a shell script, and would ssh to the host passed as an argument (argv), perform the command specified, and disconnect. (Thanks, Tiger O.)

#!/usr/bin/expect

set timeout 1
set cmd {uname -a}

spawn ssh root@$argv
expect_after eof { exit 0 }


## interact with SSH
expect "yes/no" { send "yes\r" }
expect "password:" { send "rootpasswd\r" }

expect "# "
send "$cmd\r"
expect "$cmd\r"
expect "(.*)\r"
send "exit\r
