I have uninstalled Syncthing from my computer including deleting the config files. I have done search on Sync* sync* and there seems to be no files left with that name. I have rebooted my computer and now I notice constant attempts at contacting discovery-v6-4.syncthing.net. [also v6-3, v6-3, v4-4, etc]
What process would be doing this? Is this a rogue program? Is it related to my past use of Syncthing? More importantly how to permanently kill this?
I am running latest Debian.
Thanks for any help.
