Question

I connect to a VPN from console using something like:

sudo openvpn my.conf
[sudo] password for user:
Enter Auth Username:my_user
Enter Auth Password:

I don’t care about entering the admin pwd manually but I want to automate the vpn auth, I think expect is what I need to do this but I don’t know how to use it and I never coded a bash script.

Could someone show me a simple bash script using expect so I can use it for this?

Answer 1

Something like that (untested)

#!/bin/usr/expect -f
spawn sudo openvpn my.conf
expect -r "\[sudo\] .*\: " {
    send "my_ownpassword\n"
}
expect "Enter Auth Username:" {
    send "my_user\n"
}
expect "Enter Auth Password:" {
    send "my_vpnpassword\n"
}
