| From: Val Kulkov via talk <talk@gtalug.org> | Setting "client min protocol = NT1" is indeed a bad, bad idea from the | security standpoint. | | Check out this article: | https://www.ixsystems.com/community/resources/how-to-kill-off-smb1-netbios-w... | The approach described in this article worked to fix the same or very | similar problem in my case, and it might help you with your problem too. Thanks. It sheds some light on the mess. Or stack of messes. It's written from a Windows standpoint and I've never had a Windows standpoint. The problematic devices are cheap cosumer NAS boxes. They run Linux but they are designed to fit into a Windows world. They are old and run old "firmware". The way to change them is to throw them out, but we don't tend to throw anything out here. We still have our first computer (an Altair), even if we don't actually use it. Discovery isn't much of a problem here. Every service is on a static IP address with a proper DNS entry. (Even so, network printing is another black box that just works unless it doesn't. I think mDNS is being used.)
