Here below password is mypassword

1)

root$ echo mypassword || openvpn client.conf.ovpn 

the result was display:

mypassword

2)

root$ openvpn client.warriors.conf.ovpn || echo mypassword

the result was display:

exit in this way is it normal.

Answer 1

How about storing it into a file and using --askpass /your/file? --askpass option was added in OpenVPN version 2.0-beta20, Maverick has version 2.1.0-3ubuntu1.

Answer 2

In my openvpn.conf:

...
askpass /etc/openvpn/jdoe.pass   <<< new line here
ca /etc/openvpn/jdoe_ca.crt
cert /etc/openvpn/jdoe.crt
key /etc/openvpn/jdoe.key
...

The file /etc/openvpn/jdoe.pass just contains the password. You can chmod this file to 600. This method save my life... ;-)

Answer 3

Try a shell script such as:

#!/usr/bin/expect -f
spawn openvpn client.warriors.conf.open
match_max 100000
expect "*?assword:*"
send -- "mypassword"
send -- "\r"
expect eof

You'll need to chmod +x this, you can also set it as an environment variable so you don't have to type out the directory.

Looks like they got this script to work: https://unix.stackexchange.com/questions/9055/establish-openvpn-tunnel-in-bash-script

Answer 4

I think you just swipe | and || operator.

| plug standard output o the previous command to standard input of the next command.

|| launch second command only if first command fail (exit code != 0).

this command should work.

root$ echo mypassword | openvpn client.conf.ovpn
