Hi everyone!

I just wanted to let you know that I just finished merging the work to integrate ZeroTier into the development version of OpenWISP, find more information on how to set this up here: https://openwisp.io/docs/user/zerotier.html

This feature will be shipped in the next release, if you want to try it before then you can do so by deploying the development version of OpenWISP, to do that you need to use the latest master of the ansible-openwisp2 role.

Many thanks to Aryaman for working on this during the last Google Summer of Code under the guidance of Gagan Deep, Ajay Tripathi and myself.

I am proud of the result we have achieved, as the first iteration I think it's really good.

I am eager to see this work deployed all around the world!

Best regards
Federico Capoano

Hi,

I followed the guide and everything works.
I only have one error in the topology, I created the script as described in the guide https://openwisp.io/docs/user/network-topology.html

This is my output:

root@controller:~ # /opt/send-zt-topology.sh 
<!doctype html><html lang="en"><head><title>Server Error (500)</title></head><body><h1>Server Error (500)</h1><p></p></body></html>root@controller:~ #

What could be the problem?

Thanks.

Beste regards,

Michele Salerno

I think you need to upgrade your netdiff and network-topology modules to the latest development version.

Verify that in the python virtualenv, the netdiff module has this file:
https://github.com/openwisp/netdiff/blob/master/netdiff/parsers/zerotier.py

with --force-reinstall --no-cache 

cd /opt/openwisp2
source bin/env/activate

Hi,

i force update and i have this:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

Try downgrading netaddr to 0.8.0, I do not know where netaddr 0.9.0 is coming from.
