OpenVPN Connector for arm64 on Ubuntu

smackie

Are there any plans to build the OpenVPN connector for arm64 on Ubuntu? It'd be incredibly useful for creating small connectors for backup links to remote networks.

Cheers

Please this. I want it for Kali on Raspberry PI. How nice for pen testing to be able to drop in a PI and connect in to run attacks. I know we can maintain out own openvpn server and log the client in as a gateway but that is not as convenient as your cloud is.

Hello smackie and charadeur,

I have good news for you then. OpenVPN3 Linux client version 14 beta that is being prepared at the moment will have a build for Ubuntu 20 on ARM64. I should of course point out that most smaller devices don't have a very powerful CPU, so performance may vary from platform to platform, but it'll work.

Making it available for Kali is not at this point a goal, but since OpenVPN3 Linux client is open source, and the source code is available online, you may be able to build it there yourself. The focus for platforms at the moment for OpenVPN3 Linux client is mostly Ubuntu, Debian, RedHat, and CentOS.

Kind regards,
Johan

Hello,

OpenVPN3 Linux client v14 beta is already out, we even did a v15. It runs on Ubuntu20 ARM platform. It's basically the same as installing on Ubuntu20 x86_64 platform. You can find the software here:

Kind regards,

and this will work as Connector ? I'm not looking for a vpn client but a "client" acting as OpenVPN connector, allowing clients to remote access the network behind the connector

Hello,

The connectors that you launch from OpenVPN Cloud are using this same OpenVPN3 Linux client software.

Kind regards,

Hello again stadelmannj,

Sorry, should have been clearer. You need 64 bits platform ARM. You appear to be running a 32 bit platform. The architecture known as armhf is only 32 bits. The architecture known as arm64 is 64 bit. Now the problem might be resolved if you install a 64 bit platform on your device - if it supports it. You should check if the CPU in your device is capable of 64 bit. For example a Raspberry Pi 4 is a 64 bit platform as per its CPU specifications.

If you install Ubuntu 20.04 LTS 64 bit then you should be good.

And before you ask, no, there won't be a 32 bit version of this software. We left behind 32 bit terrain a while ago.

Kind regards,
Johan

Hi Johan,
thanks for the hint. 64bit version worked 🙂
