Resolved OpenVPN Client that supports two-factor authentication

[Hack5190]

Based on my testing neither Tunnelblick (3.5.7) or the last PPC version of Viscosity (1.4.3) support two-factor authentication. It was added to Viscosity in 1.6.1 - but it's Intel only.

Do you know of a OpenVPN client that runs under Leopard on a PPC and supports two-factor authentication?

Happy to report that through a mashup of OpenVPN programs for the PowerPC I was able to get two factor working! Below are two options, paid and free.

Here is an overview of the GUI (paid) solution:

1. Install Viscosity v1.4.3
2. Download Tunnelblick v3.5.7 (Don't install)
3. Open the Tunnelblick DMG and save the program (Tunnelblick.app) to your desktop
4. Copy the "openvpn" binary from "Tunnelblick.app/Contents/Resources/openvpn/openvpn-2.3.6/openvpn" to your desktop
5. Rename "openvpn" on your desktop to "openvpn2.2"
6. Rename the existing "openvpn2.2" binary in "/Library/ViscosityHelperTools" to "openvpn2.2.old" (just in case 🙂 )
7. Copy "openvpn2.2" from your desktop to "/Library/ViscosityHelperTools"

Here is an overview of the command line (free) solution:

1. Install Viscosity v1.4.3
2. Download Tunnelblick v3.5.7 (Don't install)
3. Open the Tunnelblick DMG and save the program (Tunnelblick.app) to your desktop
4. Copy the "openvpn" binary from "Tunnelblick.app/Contents/Resources/openvpn/openvpn-2.3.6/openvpn" to some place you will remember (like ~/bin)
5. From the command prompt enter the following
   • sudo kextload /Library/ViscosityHelperTools/tun.kext
   • sudo ~/bin/openvpn --config (name of ovpn config file) --auth-retry interact
   • sudo kextunload -b com.viscosityvpn.Viscosity.tun

Thats it, enjoy!
