Finder Shows disabled smb share

[korrupto77]

Hi all,

I've recently noted, after few changes on my shares, that SMB icon is constantly present on finder even if service is down. The issue happen to all mac on the network, i've tried to reboot but no changes. I'm not able to define if this issue is after an update and specially which one can be, just 2 weeks ago i switched to afp and smb remains a "secondary" read-only share for few devices such as VM or HTPC.
Of course in SMB service "zero-conf discovery service" is not selected .
Does anyone knows how to totally hide SMB icon in finder maintaining share active ? Thanks in advance and regards.

The samba server performs mDNS registration for _smb._tcp for the server's hostname (not netbios name). If it's not running, it shouldn't be registered. What do you see if you type dns-sd -B _smb._tcp.

anodos,
thanks for your reply, here below the output of command with and without SMB service active (zero-conf discovery service is always off). there is no changes between active or not active service ..

Those 2 devices (i don't know why are duplicated) are present and active on the network but only the YYYYYY is connected to SMB share the other one should not .

Browsing for _smb._tcp.

18:35:59.403 Add 3 1 local. _smb._tcp. YYYYYYYYYY

(note: XXXXXX and YYYYY are hidden by me in order to avoid device name ... security first !!)

Thanks again for your support and Regards

The number of times that a device appears in the Browse list depends on network topology / number of interfaces in the client. If you have enabled both WiFi and a wired connection on the Mac, then both interfaces may pick up the same computer. (That's why you have `if` 1 and 2). Is YYYYY `FREENAS_SMB`?

ok, got it, it make sense that same device appears 2 time due to wifi-eth NIC's.

No, YYYYYYY is another device on the network, Freenas doesn't appear onto list, neither with SMB active, nor if not active.

Well, that means you've successfully ruled out mDNS as the reason why it's visible in finder ;)
I haven't looked closely at recent MacOS behavior. It's possibly showing based on NetBIOS-NS broadcasts from the FreeNAS server. It might be stale cached information in Finder. What version of MacOS is this?

I'm thinking too that NetBIOS is announcing on the broadcast and can be related to "lm announce", i've already tried to edit and change to "no" but after reboot is automatically "yes"

What you need to do is disable nmbd. Try pkill -9 nmbd and then run the command service samba_server status to verify that he's dead.

ok i did some test :
SMB Stopped :

nmbd is not running.
smbd is not running.
winbindd is not running

SMB Running:
nmbd is running as pid 35932.
smbd is running as pid 35936.
winbindd is running as pid 35942.

SMB Running after pkill -9 nmbd
nmbd is not running.
smbd is running as pid 35936.
winbindd is running as pid 35942.

Update :
I 'm checking if really Freenas_SMB disappear from finder(i hope so ) i noted that after pkill nmbd, SMB service is off nevertheless i can mount SMB share as usual and if I'm relaunching the service, Freenas_SMB return visible:

How do I stop definitively nmbd form being restarted after reboot or service relaunch ?

Thanks
