Is it possible to update 8.1.5 for Raspberry Pi 3B+ board support?

[Juanito]

lz4_compress.ko is not included in any extensions in 13.x, but I doubt it is needed by vtun.

Sadly, even with ppp module added seems no luck

On our server side FYI, the "instant drop" and "reconnect" shows as this if it's any help :

So that is why the compress or encryption I suspect is the issue - But hummm, not sure what I can do to poke more?

Perhaps it's interesting to note that the vtun process doesn't "die" - IOW, it stays the same PID so I do think vtun is "working" and it's maybe something related that can be solved?

The lzo extension is a dep of vtun, so it should be loaded (/usr/local/lib/liblzo2.so*).

You can obtain the lz4_compress module from http://tinycorelinux.net/13.x/armv7/releases/RPi/src/kernel/5.10.16-piCore-v7_modules.tar.xz if you wish to try it.

For troubleshooting purposes you could try replacing the piCore vtun with the one from the RPi os or debian?

[Juanito]

You could also try recompiling vtun - see http://tinycorelinux.net/13.x/armv7/tcz/src/vtun - without the debian patch 00-sslauth.patch (ref /dev/random, which is not present?).

Hi there Forum,

I thought for the benefit of this thread I would comment to say I've had no luck with another recompile of vtun

So for now I will attempt to move to open-vpn.

As mentioned, vtun is a very old programme so perhaps it has reached end of life.

BIG thank you to all who tried to assist me in making it work on TC 13 - Much appreciated.

You could try feeding /dev/random with the rng-tools extension and then retrying vtun?

$ sudo rngd --rng-device=/dev/hwrng
