samba - Jul 2002 - 5 non-answered questions.

Hello,

We have just migrated our large dev file server on linux+samba 
(Mandrake8.2+samba2.2.3a).
It works almost fine but here are some question asked by some users I can't 
answer, after reading the manuals, the FAQs...and reading this list for a 
while :

1. Why can't NT clients do several levels mkdir ?
I mean doing a mkdir toto/titi would create first a toto directory and then 
a titi directory inside. It works with an NT/2000/Netware file server but 
not with samba.
We can do it with Win2k client workstations, but not with NT.
Stange, hu ?

2. With NT clients again, we get some strange results when using the right 
click, send to option to send a text file in the notepad. Sometimes it 
works, sometimes not ("Unable to open file" error message). I crosss 
checked the unix file perms, the samba options between working and non 
working files. No way.

3. Is there a tool to simulate the MAPROOT novell command ?
    (We are doing subst but it is not very easy to use as all map are 
labelled "Network Drive")
    Again, Win2k allows "deep" drive mapping and NT not.

4. The matching between DOS attributes (archive, read only...) and Unix 
rights is something not very cool for the end user.
=> Only the owner of a file can really change them. And users cannot change 
file ownership (because only root can do this on unix)
Is there a workaround to this ?

5. I would be interested in having a link to a document (or a book) which 
explains step by step how tu tune samba to get max perf.

Many thanks for your help.

Regards,
Stephane

1.  I don't have this problem.  But if I try mkdir test/test2, I get a
"syntax is incorrect" error message.  mkdir test\test2, on the other
hand, works great.  Are you sure you dind't do it right when testing with
NT/W2k Servers and accidentally used a / when testing with Samba share?

2.  What patch level of Windows NT are we talking about?  This is
something where the Samba error logs might provide insightful clues.

3.  I don't know if there's a tool to simulate MapRoot, but this is a
Windows NT (and previous) issue, and has nothing to do with Samba.  If
nobody here provides an answer, try a Windows Admistration help
site/forum.

4.  Ya, I agree, trying to fake Windows style permissions and attributes
over a Unix filesystem can be a annoyance.  In my case, its simple to just
force user on public shares so everyone who has write access to that share
is the same user as far as Unix host is concerned.  If you need better
fine tuning, Samba implements windows ACL that should, to my knowledge,
mimick Windows permissions.  I have zero experience implementing this,
however.  Your mileage may vary.


5.  man smb.conf  -- That may sound trite, but there is no such thing as
step by step to get max performance over and above default.  Anything you
do to get more performance is highly dependant on your individual
situation, and requires careful reading/understanding of the Samba
directives.  (After all, if it were that easy to get better performance,
it would just be the default, no?)

Samba in Mandrake (since Mandrake 8.1) has out-the-box support for ACLs
on XFS filesystems. Unfortunately, Posix ACLs aren't the same as Windows
ACLs in that there is no way to let someone (non-root) take ownership of
files (AFAIK), thus this isn't available via samba. But you can at least
have finer-grained control on access.

I have had some issues with ACLs (don't seem to work on a member server,
but do work on our domain controller, should work fine on a stand-alone
box), so do a test before you decide to migrate everything to XFS ...

There is a lot of documentation that ships with samba, in the samba-doc
package in Mandrake 8.2.

Please also note that RPMs of newer samba releases for Mandrake are
available at ftp.samba.org (only latest) or
http://ranger.dnsalias.com/mandrake/samba or
