High Sierra - Can't change NETBIOS name

Hi,

I have a problem in my LAN. My MacBookAir has these correct settings:

scutil --get ComputerName

MacBook Air di Fabio

scutil --get HostName

Air-di-Fabio

scutil --get LocalHostName

MacBook-Air-di-Fabio

But in the Advanced Network Preferences, I have a NetBios name of: Saltydog-A3 (which is the hostname of my smartphone on the LAN).

I can't change that NetBios Name as it appears stuck. Every time I try to change it, it reverts back to the smartphone name.

If I connect with ssh to my media center, I always get this message:

Last login: Sat Oct 21 11:18:49 2017 from saltydog-a3.station

My router, instead, lists the correct HostName of the LAN.

Any help?

Thanks

MacBook Air, macOS High Sierra (10.13)

System Preferences - Sharing, Computer Name perhaps?

No. That's ok either.

Has the media center, DNS service enabled?

Alberto, the problem is in the Mac, not in the media-center. All devices in the LAN get the DNS resolution from the router.

What does return the command

plutil -p /Library/Preferences/SystemConfiguration/com.apple.smb.server.plist

Yes, I tried that too last week, but unfortunately it doesn't apply to High Sierra and it didn't work. Thank you anyway!

I guess you already tried setting the computer name from the command line

scutil --set ComputerName whateveryouwant

scutil --get ComputerName

MacBook Air di Fabio

Please change "Nome computer:" from MacBook Air di Fabio to

MB Air di Fabio

and tell me if NetBIOS name turned into MB-AIR-DI-FABIO

I'll tell you why in the next post.

Oct 23, 2017 2:48 PM in response to fabio56

NetBIOS name will probably be the same after you renamed the computer to MB Air di Fabio

that is SALTYDOG-A3

If it is any consolation I tried that suggestion too and My Netbios name remains unchanged. Thankfully it is of no problem to me as far as I am aware (yet).

Sorry. Maybe I wasn't clear enough. What I meant it wasn't turn off Wi-Fi on the computer, but turn off the Vodafone station altogether.

I'm glad to have been useful.

Now I understand why you like so much the command line 😉
