How to create hotspot wifi?

English Network/Internet
1

Hello everyone!
Try to share wifi with my laptop and Tumbleweed. After i create a connection and activate it(WPA2 Personal), i try to connect from my Android device and stacking at getting IP address. Journalctl type me this information:

kernel: netlink: 'wpa_supplicant': attribute type 213 has an invalid length.

I found bug report on redhat forum, but for me it doesn’t work. Report
Quote from report:

> > # nmcli connection edit <your hotspot>
> > > set 802-11-wireless-security.pmf disable
> > > save
> > > activate

Anybody know something about this problem? If it’s a bug, how can i make a bug report?

You first have to describe in detail what you did to try to create a WiFi hotspot,
And display the exact errors you get.

Your detail should be enough so that someone can follow the same exact steps and replicate your problem.

If in the end others might agree that you didn’t overlook something, then a bug can be submitted to https://bugzilla.opensuse.org

As i see, there is also problem with dnsmasq.

ps -aux | grep dnsmasq

shows me 2 process,with root and dnsmasq users. Is it right? How to fix problem with rights?

What do the permissions look like?

ls -l /var/lib/NetworkManager/dnsmasq-wlp2s0.leases

I have no such file. But all files in folder belongs root - root and have 644 access rights. Folder NetworkManager has chmod - 700 and also belongs to root - root.

This cannot be the issue, running TW here, wifi working properly, hotspot as well, and I don’t have that file either.

I wouldn’t expect you to - that file is specifically reported in the user’s own log. The log reports…

окт 28 10:47:31 Hastur dnsmasq[15406]: cannot open or create lease file /var/lib/NetworkManager/dnsmasq-wlp2s0.leases: Permission denied

I should have requested the ownership details for the parent directory instead. I also wonder what dispatcher scripts the OP may have employed here. NetworkManager’s hotspot functionality should just work (as it does for me).

I had the same issue so I opened https://bugzilla.opensuse.org/show_bug.cgi?id=1114680

My solution was:

— /etc/apparmor.d/usr.sbin.dnsmasq~ 2018-10-22 11:53:18.000000000 +0200

So, a problem with apparmor-profiles (specifically /etc/apparmor.d/usr.sbin.dnsmasq configuration). Thanks for sharing the bug report and resolution.
