Question

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:

exit in this way is it normal.

Answer 1

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 2

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.
