I have searched for this and the solutions I found were for instances
where the workgroup name *was* too long. However, my workgroup name is
*not* too long. The spaces between PEGASUS and ^[ are part of the
message, I did not add them. If you count them there are 16 total
including ending ^[. I can't figure out where the spaces are coming from.
This is the same for every Samba server. Each machine will show this
message for the other servers but not itself. MachineA will show message
for B and C, but not A. MachineB will show message for A and C but not B.

Servers are Fedora release 20 and 21, Samba versions are 4.1.12 and 15.

PEGASUS ^[ is too long. Truncating to

I can count 17 characters...

According to Microsoft:

"The NetBIOS naming convention allows for 16 characters in a NetBIOS name.
Microsoft, however, limits NetBIOS names to 15 characters and uses the
16th character as a NetBIOS suffix. "

and

"All NetBIOS names are 16 characters in length. A NetBIOS suffix is the
16th character of the 16-character NetBIOS name. The NetBIOS suffix is
used by Microsoft Networking software to identify functionality installed
on the registered device. "

http://support.microsoft.com/kb/163409

Names are padded with spaces to 15 bytes, plus the NetBIOS suffix in the
16th byte.

I understand the limit is 15. However, in the case I included, the count
is only 7.
I did *not* add the spaces nor the ending character (I assume it is some
control
character). The line below is straight from smb.conf

workgroup = pegasus

All the machines I am referring to are Fedora.

Thank you.

I suppose that the correct answer has been already given to you by Reindl
