Unable to ping other peers on netbird network #1506

Open bmcgonag opened 5 months ago

bmcgonag commented 5 months ago

Describe the problem

I have setup a netbird self-hosted network with Authentik as the IdP.

I have added two linux devices and one iphone.

I try to ping from one linux machine to the other on it's netbird ip address.

netbird status -d on each linux machine shows the other as a peer, as well as the iphone as a peer that is currently offline.

I saw some other posts about similar issues where the person found their turn server config to be incorrect.

I used the site at https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ to test my turn configuration and get the following:

0.141   relay   5   udp xxx.xxx.xxx.xxx 63425   5 | 32287 | 255     
0.166   Done

I believe everything is setup correctly, but still I am unable to ping the other machine successfully.

In the management.json file I also verified that the turn server credentials match those in the turnserver.conf file.

I have setup 1 extra group called personal, and added all three machines to it. I added an ACL for that group to allow traffic between the machines in the group and made sure it's enabled. Additionally, I have not removed the 'ALL' group, just to be able to compare and contrast having ALL enabled or disabled. No difference.

To Reproduce

Steps to reproduce the behavior:

  1. Setup Netbird on a self hosted installation.
  2. Set it up to use Authentik (I don't think this is the issue)
  3. install netbird clients on 2 linux machines.
  4. Add the machines to a group.
  5. create an ACL to allow the machines in the group to communicate.
  6. enable the ACL.
  7. try to ping one machine from the other.

Expected behavior

I would expect communication between the machines in a group being handled by an ACL to allow communication. At the very least I would expect the machines on the ALL group to be able to communicate.

Are you using NetBird Cloud?

bmcgonag commented 5 months ago

Additional information. I updated my fedora client to 0.25.5-1, and still see the same issue.

bmcgonag commented 5 months ago

I completely remade my setup using a new domain name, and still have the following:

  1. Each peer can see the other peers in the all group when doing netbird status -d.
  2. One peer can resolve the ipv4 address of the other peer when trying to ping by netbird hostname, but no ping is ever successful.
  3. Neither peer can successfully ping the other by ipv4 or hostname.

Watched the logs of the docker compose up -d when I started up the new system. Had no errors at all.

Everything appears to be communicating properly, except the clients can't seem to communicate with each other. No idea why.

Any help is greatly appreciated.

wisetux commented 5 months ago

Hello @bmcgonag, please confirm the VPC you are using to host NetBird server. Might be an issue with reachability to Coturn. Are you able to ping different hosts on same network using their NetBird hostname?

bmcgonag commented 5 months ago

I'm using Digital Ocean. I posted my coturn test results in the original message using Trickle-ice. I don't think that's the issue, but not 100% ceertain of that.

I am unable to ping the hosts by IPv4 or by Hostname. Any direction or help is greatly appreciated.

bmcgonag commented 5 months ago

also @wisetux the server I have setup is 1vCPU and 2GB RAM running Ubuntu 22.04 LTS server. Nothing else running on that server, just Netbird.

wisetux commented 5 months ago

Thank you for the info. The server specs should be fine as NetBird is very light on resources. However Trickle ICE output looks a little different. This is what I have:

Can you try connecting from a different network or a mobile Hotspot maybe?

bmcgonag commented 5 months ago

Ok, yeah I see how your's is different. Any idea what it might be @wisetux ? I have my own Coturn server setup that I use for Matrix, NextCloud, and others, but it uses "static-auth" not "lt-cred-mesh". Can Netbird do "static-auth"?

wisetux commented 5 months ago

I'm not well versed with Coturn server setup and I use a dedicated instance just for Netbird. Maybe this issue might give you more info regarding static-auth configuration: https://github.com/netbirdio/netbird/issues/569

magixus commented 5 months ago

Do you have DNS resolv issue ? Maybe one of the ERROR below in /var/log/netbird/client.log

bmcgonag commented 4 months ago

No. Checked logs, and no errors shown. I have a few WARN, and a lot of INFO states, but no ERRORs logged.

Even tailed the logs while logging in, as well as trying to ping the peer after login.
