Synology DS418j

Does not go online / can not join network

DS418j Realtek RTD1293 Dual Core 2 Yes rtd1296 DDR4 1GB

[joseph-henry]

I think the RTD 1293 and RTD 1296 use the same package architecture. Try this: https://download.zerotier.com/dist/zerotier-1.2.4-syn-rtd129x-6.1.spk

Since I don't have one of these devices in-house it would be fantastic if you could let me know if this fixes your problems (or creates others).

Thanks

It worked once after installation. After restarting the station, it is "deaktivated", and I have to go to activate the app again. Then it shows connected and online in zerotier, but ping / ssh / etc. over the IP in zerotier have 0% answers.

How can I further support you to debug the issue? What commands / syslog / etc. do you need?

[joseph-henry]

For convenience you can start stop and check the status via:

/etc/init.d/zerotier start
/etc/init.d/zerotier stop
/etc/init.d/zerotier status

Also did the NAS install any updates during that restart?

[plieningerweb]

The commands are not there. /etc/init.d does not exist. Only /etc/init, which contains config files only.

I restarted the NAS manually and there were no updates installed.

Same issue here on DS414j with the new comcerto packages. It worked with automatically assigned IPs, not with a manually set one (from zerotier web interface). It worked for all my other nodes. So I restartet, and now I cannot get it working again. Stopped, started, uninstalled and installed again. The network interface shows up, but only with IPv6 address, and zerotier is stuck at requesting configuration.

/e: After rebooting, restarting, reinstalling and removing and recreating the zerotier network (deleting it at my.zerotier.com) it works, as long as I let it auto-assign the IPv4 address.

/e2: ...and it is not working again. Shown as offline in my.zerotier.com, though as online in Zerotier inside DSM, with status OK for that network.

The Synology cli for services is

synoservice --status pkgctl-zerotier
synoservice --stop pkgctl-zerotier
synoservice --start pkgctl-zerotier

[plieningerweb]

How can we debug it?

[joseph-henry]

Check for the presence of a watchdog process and the zerotier-one process via:

ps aux | grep zerotier

It should output something like the following:

12946  0.8  0.6 145344  6244 ?  8:46 /usr/local/zerotier/bin/zerotier-one -d
12002  0.1  0.1  11793  1698 ?  1:47 /bin/bash /usr/local/zerotier/bin/ztui_watchdog.sh -daemon

Then, also check for the presence of a /dev/net/tun.

It could be that the process is failing to start, or that the TUN is being torn down on restart.

It could also be that the initialization script is buggy. You can see that by inspecting /etc/init.d/zerotier.

[joseph-henry]

Also,

/opt/var/log/zerotier-one.log

Will contain some logged activity. I can add more to what's logged if we can't figure it out from here.

Is there a verbose / debug flag for zerotier-one?

[plieningerweb]

Any ideas / help how I could further debug this/support you? Would be really really nice to make it work soon, as of right now we can not ssh into the box from remote.

[joseph-henry]

If anyone is still experiencing GUI problems can you provide me with the following information:

• Browser (version if possible)
• Specific errors from your Browser's console
• Extensions installed (try disabling them to see if that helps)
• Any information about how you're remotely connecting to your NAS
• Whether you have a firewall enabled
• Any non-default settings on the NAS

Thanks for your patience.

[thunfischbrot]

Thank you for your patience.

Browser: Tried Firefox 57.0.4 on macOS and Windows 7, as well as latest Chrome on macOS and Windows 7.

Console says Error: Minified exception occurred; use the non-minified dev environment for the full error message and additional helpful warnings. react.min.js:15:19949 as soon as Zerotier window is opened, every two to three seconds.

Disabled all extensions, restarted, reloaded, same.

Both direct access via internal IP, via VPN and via Synology Quickconnect exhibit the same behaviour.

No firewall.

I set up the NAS on the same day I installed Zerotier the first time, I guess there are few non-default settings.

[joseph-henry]

Interesting. I can actually replicate the issue when accessing via QuickConnect.

[thunfischbrot]

I re-installed and checked again. It takes a while, but it does show up locally:

This is great, I think I was just too impatient the last time! Still doesn't work via quickconnect, but that's not a major issue for me.

[joseph-henry]

@thunfischbrot I'm very glad to hear this! I will keep working on a solution for QuickConnect. And yes, some of the ARM-based models seem to struggle with the authorization and identity generation task for some reason.

Pre reboot:

$ ps aux | grep zerotier
root      7765  0.2  0.1   3332  1664 ?        S     2017  93:48 /bin/bash /usr/local/zerotier/bin/ztui_watchdog.sh -daemon
setup    27152  0.0  0.2  16612  1924 pts/2    S+   13:14   0:00 grep --color=auto zerotier

After reboot:

$ ps aux | grep zerotier
root      7519  0.2  0.2   3220  2352 ?        S    13:17   0:00 /bin/bash /usr/local/zerotier/bin/ztui_watchdog.sh -daemon
setup     8473  0.0  0.2  16612  1952 pts/1    S+   13:17   0:00 grep --color=auto zerotier

Seems like the init script is totally broken. /usr/local/zerotier/bin/ztui_watchdog.sh -daemon does have the wrong path to zerotier, not /usr/local/zerotier/bin/zerotier-one. Furthermore it would only be started if no tun device exists. But its already there after a restart.

I will now reinstall zerotier once again, and check at the clean install if it would work if I ran it from ssh.

[plieningerweb]

After reinstall and no reboot:

Its connected and ps aux shows running

$ ps aux | grep zerotier
root     14697  0.2  0.2   3204  2464 ?        S    13:48   0:00 /bin/bash /usr/local/zerotier/bin/zerotier-watchdog.sh daemon
root     14704 18.8  0.8 142472  8340 ?        Rl   13:48   0:11 /usr/local/zerotier/bin/zerotier-one -d
setup    17699  0.0  0.2  16612  2092 pts/1    S+   13:49   0:00 grep --color=auto zerotier

Ok, after restart still there. I noticed that the file /usr/local/zerotier/bin/zerotier-watchdog.sh changed quite a lot compard to the one I had before the reinstall. Seemed like the version was substaintially updated since last time. Didnt know that. Zerotier is working for now (configuired over local IP in webinterface). Thanks for the awesome range of hardware support. Where can I donate or otherwise support this project?

[joseph-henry]

@plieningerweb Glad it seems to work, thanks for your help. The only way we have set up to receive donations is via cryptocurrency. But really the most valuable thing to us is your continued patience and spreading the word.

I'll close this ticket soon unless anyone objects.
