[Samba] nmbd error: workgroup name is too long

I found a similar thread in this mailing list from a few years ago, but it looks
like there was never a clear resolution.
(https://lists.samba.org/archive/samba/2015-February/189450.html).

I’m fairly frequently receiving the following error in my logs:

Feb  5 11:16:22 hal nmbd[19333]: [2018/02/05 11:16:22.889584,  0]
../source3/nmbd/nmbd_workgroupdb.c:57(name_to_unstring)
Feb  5 11:16:22 hal nmbd[19333]:   name_to_nstring: workgroup name COOMBS       
^[ is too long. Truncating to

I’m running Samba 4.7.4 on FreeBSD 11.1. My smb4.conf file has the workgroup
name as “COOMBS”, with NO trailing spaces. Here’s the complete configuration
file:

[global]
	workgroup = COOMBS
	server string = Samba Server Version %v
	netbios name = HAL

	security = user
	encrypt passwords = yes
	passdb backend = tdbsam

	wins support = yes
	domain master = yes

	interfaces = 192.168.1.220
	bind interfaces only = yes

[Plex]
	path = /zraid/plex
	valid users = plex
	writable = yes
	browsable = yes
	read only = no
	guest ok = no
	create mask = 0666
	directory mask = 0755

In the prior thread, there was speculation of some invisible control character
at play. I typed the above configuration file manually--with no copy/paste--so
that should not be the case.

Note that the error only seems to appear if "domain master = yes” is set.

The netbios services do see to work—I just get my logs filled with these errors.

Any suggestions?

Thanks,

Kirk Coombs

no, that nonsense started also with servers not part of a domain and 
even nmdb not used/started at all some years ago

[Samba] nmbd error: workgroup name is too long

Open a random text editor. 

Goto this line : workgroup = COOMBS 

Press end and remove the spaces behind COOMBS, keep removing untill the line
below it moves one up.
Then hit enter and restart samba.

[Samba] nmbd error: workgroup name is too long

Louis, thanks for the suggestion. I deleted everything between the “B” in COOMBS
and the first “e” in “server” and re-typed it all (including the new line) using
nano. I even got rid of all the space (tab) before “server”.

I restarted samba (including nmbd) and same result.

what do you get if you increase you log level at 4 or 5 and restart your 
samba ?
    log level = 5

By the way, Samba-AD works great, you really should upgrade your 
standalone fileserver. And it is a good thing to avoid NetBIOS 
altogether and stick to DNS. If you disable nmbd, the message will 
probably go away...

Cheers,

Denis

With log level = 5, the error always appears immediately after the following
entry:

[2018/02/06 18:29:09.090976,  5]
../source3/nmbd/nmbd_browsesync.c:447(get_domain_master_name_node_status_success)
  get_domain_master_name_node_status_success:
  HAL(192.168.42.220) is a domain master browser for workgroup COOMBS        
ESC. Adding this name.

so:

[2018/02/06 18:29:09.090976,  5]
../source3/nmbd/nmbd_browsesync.c:447(get_domain_master_name_node_status_success)
  get_domain_master_name_node_status_success:
  HAL(192.168.42.220) is a domain master browser for workgroup COOMBS

UNICAST_SUBNET: name_to_nstring: workgroup name COOMBS         ESC is too long.
Truncating to
  found.

These also appear to be the only log entries in which the workgroup name appears
as “COOMBS         ESC". Everywhere else in the logs the workgroup appears
as “COOMBS”. For example:

[2018/02/06 18:29:09.091062,  4]
../source3/nmbd/nmbd_workgroupdb.c:165(find_workgroup_on_subnet)
