Adding peer by bulk do crash dashboard

[zverstal]

Hello WGDashboard contributors,

When I try to add peer (even 1) by bulk everything is crash and wg-dashboard.service is go down.

OS Information:

• OS: Ubuntu 20.04.4
• Python Version: 3.8.10

Hi, do you mind running the dashboard with ./wgd.sh debug and try to add peers by bulk, to see that the error message is?

[zverstal]

Debug mod

[zverstal]

Also if I try to add another DNS to peer sometimes it's crash with EMPTY RESPONSE ERROR too.

[donaldzou]

Hmm, could you please post the terminal output when you're adding DNS and add bulk peers?

[zverstal]

Hello,

I'm back with logs.

So, i have 2 situations:

1. I get unlogin when try to add peers by bulk:

2. If I login again and try to add peers:
   I have this. Just stopping of ./wgd.sh
   

[donaldzou]

Hmmmmm this is interesting, I will look into it. Could you tell me if you're running the dashboard behind any network settings, such as proxy?

[donaldzou]

Also I'm thinking, did you block your browser to set cookies? Because that's how the user info store.

[zverstal]

No proxy setting in my dashboard. I'm running it by default way (on my server external IP).

And i don't block any cookies. Just tried to add peers on Edge with default settings - result the same, dashboard is go down(

[donaldzou]

This is super weird... seems like your browser did not send the username and password successfully. Maybe did you have javascript disabled? or maybe your system is blocking it to fetch 3rd party libraries. This issue is kind of related to your issue: #137 (comment)

[zverstal]

I haven't disabled Javascript, checked it in browser setting (i haven't changed any default settings in Chrome|Edge btw). I turned off any extensions and it's not help me either :(
And I don't have any blocklist on my Ubuntu... Even don't know how to set up it :)

[zverstal]

ipconfig /release.
ipconfig /flushdns.
ipconfig /renew.
netsh winsock reset.

Delete browser history, cookies etc done too, not helping :(

[donaldzou]

This is weird... could you take a screen shot of your browser console output when you visit your dashboard?

[zverstal]

1. Log in, no errors, 200 status of JS components

2. Trying to add peers

3. Errors in JS

[donaldzou]

This tells me that net::ERR_EMPTY_RESPONSE usually occur on the browser side... Do you mind try another browser, like Edge or Opera?

[zverstal]

Same situation in Edge and Opera (this one installed right now without any imports, just clean installation)

[zverstal]

I think there's something in searching available IPs in database maybe?

[donaldzou]

I don't think so, because you can load peers. Just wondering, which version of dashboard you're using?

[zverstal]

3.0.6

[zverstal]

And yeah, i updated it from 2.3.8 and have new database.

Also I have another server with clean installation of your dashboard (3.0.6), same errors in it :(

[donaldzou]

Hmmmmmm does your server exist locally? or is on the cloud?

[zverstal]

Cloud server.

[zverstal]

Should I see here available IPs?

[donaldzou]

Yes, you should be. Do you mind tell me what Address you have for this configuration? the dashboard might crash when it is trying to generate too much IP.

[donaldzou]

the dashboard will generate available IP based on your configuration's address, if you have your subnet's mask less than 20, it will take a long time to generate them.

[donaldzou]

the dashboard will generate available IP based on your configuration's address, if you have your subnet's mask less than 20, it will take a long time to generate them.

I forked this wonderful document on WireGuard: https://github.com/donaldzou/wireguard-docs

[zverstal]

I have 10.66.66.Х/32 for my configuration.

[zverstal]

https://github.com/angristan/wireguard-install

Maybe you know this popular installation script for Wireguard.
It's default network in this script 10.66.66.Х/32.

[donaldzou]

Ohhhhhh, you might use the wrong file lol. This script will generate 2 files (i think), one for server, one for client. The server's .conf's [Interface] have Address = xx.xx.xx.xx/24, and your client's .conf will have Address = xx.xx.xx.xx/32

[donaldzou]

For a server, the address should have at least 1 available IP for the client, so if your server's configuration have Address = xx.xx.xx.xx/32, you should change it to /24, then it should be good, remember to switch off the configuration first. I'll look into the install script you used to see what is going on in there lol

[zverstal]

from my wg0.conf
it's 24 mask

[zverstal]

And peers have 32 mask, yeah

[donaldzou]

from my wg0.conf it's 24 mask

This is the first time i'm seeing 2 lines of Address, usually they exist all on the same line like Address = 10.66.66.1/24, fd42:42:42::1/4, can you switch wg0 off with wg-quick down wg0, and remove the 2nd line of Address, save it, and bring it back up to see if that solve everything lol. I know my dashboard did not designed on handle 2 lines of Address. I need to put that into my next release.

[zverstal]

It WORKS!!!

Thank you a lot!

But problem here:

this one is not working

If I delete IPv6, everything works well.

[donaldzou]

Yessss!!! I do notice it does not handle IPv6 well. I will continue to look into that.

[zverstal]

Could I close this issue? For me it's solved :)

[donaldzou]

I'll close it ;) Have a great day/night!
