“Shared to other computers” not working on Lubuntu 18.04 and up












1















I have a laptop with a WiFi card, and an ethernet port. I also have a desktop with only an ethernet port.



On Lubuntu 16.04.1 I could give my desktop internet access by going to Edit connections (nm-connection-editor), Wired Connection, and then, in the IPv4 and IPv6 tab, setting the drop-down box to Shared with other computers. This worked like it should.
I recently tried a fresh install with Lubuntu 18.10, and I couldn't share my internet anymore. I then installed Lubuntu 18.04.1 (which I am on now), and it still doesn't work.



When I made a live USB with Lubuntu 16.04.1, and boot it, it does work.



Any help is appreciated,



Wessel



EDIT: I am using a standard Ethernet cable, not a crossover cable.

  • Hmmm.... I'm probably out to lunch, but I wonder if 18.04 broke auto-crossover for your NIC... if you're just using a standard ethernet cable to connect the two machines, try a crossover cable just for grins.

  • I am indeed using a standard Ethernet cable, I'll edit my question. I currently don't have a crossover cable, sadly.

  • Is the desktop obtaining an IP address with your current config? Do you have dnsmasq installed and configured? ps auxc | grep -i dns. Report back to @heynnema

  • Sounds like a bug or a regression to me. bugs are off topic here.

  • @GamingWessel hmm ok, well, it might be worth a $5 experiment, I dunno.
