I tried the method with different parameter

I have password.
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:

Thu Jun 28 00:00:00 2012 us=757575 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables  
Enter Private Key Password:

(still need to enter password manualy )

I don't want to have to enter the password manually. How can I achieve this?

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... ;-)
