How about testing with ethtool?
I just tried to understand a bit ethtool's man page. With not much success, I must confess... What could I find out with it, and how? The problem is that everything works perfect for some days without any problems, and then all of a sudden it stops working. As much as I know, my switch doesn't have a log. I could do, of course, some tests after it happens the next time, but which ones? -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com
