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

[Rich]

Hi onelife

... not sure if that was needed ...

Yes, that is needed. When you load  compiletc.tcz  it loads all of the extensions required for a proper tool chain. In the
past I've seen people have problems because they loaded just gcc, make, and a couple of others instead of compiletc.

[onelife]

Okay. Great - yay one thing right. Now to understand the error. But as I say I could be doing completely the wrong thing, although it's a script you just run so I'm sure something can't be right unless I'm really missing something.

Looking at all the lines of code that run during the compile I can't say I know enough to move forward.

Any suggestions on how we can build vtun?

Thank you.

[Juanito]

The main problem is that the new openssl breaks vtun.

You'll need the patch set from here: http://deb.debian.org/debian/pool/main/v/vtun/vtun_3.0.4-2.debian.tar.xz

..then, using vtun-3.0.4

* load the compiletc, openssl-dev and lzo-dev extensions
* apply the patch set
* overwrite config.sub and config.guess with the files from the libtool extension
* edit the configure script and correct the lines staring with for p in $LZO_HDR_DIR, $SSL_HDR_DIR, $BLOWFISH_HDR_DIR..
* ...for the actual location of the headers
* run the configure script with the piCore standard flags
* make
* sudo make install

Thank you for that Juanito,

I can try but this isn't something I haven't done before and not really sure - As I'm using vtun commercially I'm more than happy to pay for this to be do - Are you in a position to maybe do this? If so we can chat and send me a paypal invoice to tackle it?

I have no idea how long that would take even though the steps sound simple - But happy to make it worth your time and effort - Please let me know.

Kind Regards.

The extensions in the repo are user contributed for free 

I'll try to compile vtun for piCore in the next couple of days.

[Juanito]

posted - not tested

[onelife]

Wow - That is super awesome that you compiled it - Sadly I installed from the repo and it seems to not be working

It fires up but then dies immediately - I've tried with exact same config that works on other systems but no luck.

I thought maybe the openssl version would make a difference? The new vtun is :

OpenSSL 1.1.1g  21 Apr 2020

And on the server side is :

OpenSSL 1.1.1  11 Sep 2018

Would that maybe make a difference?

If not, I'm really not sure how would I check this should work beside a config that I have already done?

Sorry to be helpless here - But any ideas?

Thank you!

[Juanito]

Does “sudo vtund -n” give any useful error messages?

Is the ipv6-netfilter kernel modules extension required?

[onelife]

nope, vtund -n gives the normal "usage" command - So I wonder if that info is given does that mean all is good?

I installed the ipv6 net filter and that seemed to make some difference in that now the tunnel comes and drops, up and drops - It's as if the session opens but then is immediately closed - rather odd.

I then also installed iptables as thought maybe that would help but no further progress. It's odd, on the server side I get the connection but then immediately closes again. On the client side I don't actually see the vtun interface come up at all.

Any other ticks you can think of that I might need to poke at?

Thank you again

[Juanito]

The piCore-13.x openssl is 1.1.1k, so there maybe a mismatch, but I doubt it.

Vtun is old and many patches were applied - perhaps the problem is there?

[Juanito]

Does vtun need pppd and/or the ppp kernel modules (the latter are not present in piCore-13.x)?

[onelife]

yes, it seems to reference that on the config - I in fact tried to look for ppp "tcz" but no luck - Is that something easy to bring into tv 13?

[Juanito]

The ppp extension exists in the piCore armv6, armv7 and armv7l repos - which model of RPi are you using? (Note that I will add the ppp kernel module extensions shortly.)

If I understand correctly, you had vtun working without problems with piCore-8.x, but the ppp extension does not exist in the 8.x repos.

[onelife]

Yip, you are 100% right - our current TC 8 doesn't have pppd.tcz installed - but the config seems to reference it - So maybe it's not valid at all

If I compare modules - our current working TC 8 has :

Perhaps you can see something - Maybe the lz4compress? Although that tcz is installed on TC 13 - Maybe the module is just not loading in TC13?

Chat now - Thanks

[Juanito]

ppp-modules-KERNEL added to piCore-13.x repos and ppp dep file added.

Note that the extension is called ppp and not pppd, but it contains pppd.
