Yes. I do watch the samba mailing lists carefully. I do try to help as
many people as I can. I have just flown back grom Germany to the USA and
have been a little jet lagged, and that has caused some delays in my
responsiveness. But I will try to assist since you have written to me
directly for assistance.
I am updating the HOWTO documentation in preparation for the release of
Samba-3.0.0 so I also have to balance my time so that the document will be
sufficiently complete. We are updting this document every few days at the
moment so it would help to keep checking for updates.
FWIIW: If anyone wishes to pay for support I can guarrantee them 100%
satisfaction and 100% attention until their problem is completely solved.
I am sure that in this situation they and I would be completely happy as
the paying person would get a relatively painless solution and I can pay
my rent. :) I would not make this comment except that you wrote to me
directly asking for help.

If you care to use SWAT (the Samba Web Admin Tool) you will find the
smb.conf parameters reasonably well laid out. nmbd handles name resolution
and does browse list handling for samba. The configuration parameters
involved in nmbd's operation are:
* os level
* preferred master
* local master
* domain master
Name Resolution Method:
* name resolve order
* wins server
* wins support
WINS Server and WINS Support are mutually exclusive options.
Those marked with an '*' are the only options that commonly MAY need to be
I should point out that even if not one of these parameters is set nmbd
will still do it's job. The details of how browse list handling works is
documented in the Samba-HOWTO-Collection. The current version of this
document is available from the Samba web site. I would refer you to (for
example): http://us1.samba.org/samba/docs/ for a collection of documents
that might help you. In particular I would refer you to:
Please read carefully chapters: 3, 23, 24
I hope helps to answer your question.
I agree that the Samba-HOWTO-Collection is still a crappy piece of work,
after all, that is the feedback we have been getting. I'll bet that those
giving this type of feedback have not checked how this document has grown
It clearly needs input from someone who can better organise the
information so that evreyone will be able to find the answers they are
looking for. I would value your feedback and contribution. If someone
would just help out we would all appreciate their effort and give them
abundant credit for their contribution.
I am doing my best to try to rearrange this document to improve it's value
- but I am an expert and not a novice - so I have no trouble locating
information I need. That makes me a bad editor and you the very best
source of feedback - if only more people like you would offer some help.
The type of help we need is in the form of concrete recommendations,
preferably with details on what to re-arrange, where and how, what
headings to use, what information is missing. My crystal ball is worn out.
Samba is user supported software. That means you can make a difference. In
the least it would help a great deal if you could document in detail how
you went about solving your problems. If I could get some indication of
the approach people take then I can re-write and add documentation that
will be better organised to meet user needs.

So have you used a tool like ethereal (see www.ethereal.com) to see what
information nmbd (udp ports 137 and 138) is sending out?
Have you followed chapter 33 of the above document to find a possible
explanation for the problem you are seeing?

The minimum configuration is:
workgroup = WORKGROUP
path = /tmp

The most common cause of browsing problems is inconsistent or broken
TCP/IP configuration on either the samba server or on the MS Windows
The second most common problem today is that most Linux systems come with
some sort of firewall enabled that effectively filters out all samba
Samba is a complex application, but it's default settings are carefully
chosen so that even the above minimal configuration should work. If you do
not see your samba server in the client browse list after a 45 minute
period then somethings is sadly broken - and that is most unlikely to be
I hope this answer points you at the solution. More so, I hope I will
receive your edits to the Samba-HOWTO-Collection that will make your pain
and agony and the need for me to write a custom reply like this totally
unnecessary in the future. Will you help me please?
