I plugged in a usb nic, no go - didn’t even show up IIRC. All of them get link and activity, I suppose I better chang Cable, never know, maybe a cat rolled a chair over patch cable.
I have this because it used to belong to the furniture company my wife worked for and I originally set it up for pc back ups for them. Total overkill, but they wanted ftp shares also to supplement dropbox. Anyway when co went under, some ■■■■■ dropped the server on its face, and when it was offered up, I took it for nothing. It is fully functioning as far as I can tell - It lost the OS somehow, I had all passwords and all, but I think someone played a bit hard with it and then got disenchanted. So there was no chance of recovering original load. It would not load Debian nicely, but it did take the eval 2012 SS you suggested, and quite nicely except the NIC functionality. I even downloaded the WD specific software and loaded it up.
And now you know the rest of the story. BTW, my aim is to make this the central component in a home security system.
