Re: [Samba] Ghosting Linux Partitions.

This is a bit OT, but I have used Ghost with ext2 partitions with no
 problems whatsoever. I'm not sure if ext3 is supported or not.
Same diff; any ext2-based tools work just fine with a clean 
ext3 partition. So just make sure to shut down cleanly 
before using ghost.

Re: [Samba] Thanks Samba Community!!!

So it isnt the rpm packaging per se, but I would bet that it is related. 
RH did a lot in 8 and I think it was overly ambitious.
It's pretty much a rule of thumb to *never* use a RedHat .0 
release. Believe it or not 8.0 was a lot better in this 
respect than many previous ones.

Hopefully 8.1 is out soon since 7.3 (which I've been *very* 
impressed with) is EOL'd at the end of this year.

Re: [Samba] Re: Re: Hiding a share

2003-03-03 Thread Jon Niehof
Correct. That is why samba has a 'browseable = [ Yes | No]' option.
Go figure.


Which, in turn, leaves the share still visible in Network Neighborhood 
etc, as I initially reported.
Go figure. :)
IMX browseable = No in the share section doesn't hide the 
share from appearing in Net Neighborhood (didn't test to see 
if it hides the *contents* of the share--i.e. if you need to 
know full path into the share to access files in it.) 
browseable=No in the global section works as expected. This 
is with 2.2.7a; YMMV, NRWS, DNEYS, etc.

You probably didn't install development packages when

Re: [Samba] Unable tp map to a samba share from home

2003-02-24 Thread Jon Niehof
I have a filtered restriction on port 139 Why ?
*puts on mindreader cap*

I suspect what you're trying to say is that you have a samba 
server running at home (as a guess--on comcast's cable modem 
service) and are trying to access it remotely, but it fails 
because port 139 is filtered.

*If* that is the case, I would further suspect that comcast 
is intentionally filtering smb/cifs traffic on their net so 
as to somewhat impede rampant file trading and also to 
protect folk who run unsecured windows machines on their 
networks. Those boxes get rooted, customers blame comcast. 
Worse, those boxes become DDoS zombies, *everyone* blames 
comcast.

SMB over the Internet is a Bad Idea IMO. Look into a VPN or 
SSH tunnel if you *really* need it.

why does samba open and close the file so many times? this is the login

*Samba* is not opening and closing the file that many times; 
the client side is. COMMAND.COM and cmd both process batch 
files one line at a time; I haven't tested this but I 
suspect cmd opens the file, reads a line, closes the file, 
executes the line.

You can check this for yourself from the Windows side with

Re: [Samba] Samba, rsync and a newbie sorting it out...

2003-02-19 Thread Jon Niehof
I'd like to use rsync as a way to back up Windows devices on a network, 
pulling data off of the Windows boxes and putting it onto a Samba share. 
Is this even possible? I suspect I either need some sort of rsync 
implementation on Windows (ha!) or I need to have Samba know to reach 
into the boxes and get the info for rsync-ing. Doable? A fool's errand?
I'd recommend installing rsync 
(http://optics.ph.unimelb.edu.au/help/rsync/rsync_pc1.html) 
on the windows machines, installing PuTTY 
(http://www.chiark.greenend.org.uk/~sgtatham/putty/), 
creating ssh keys for the windows machines to log into the 
BSD box, and make a scheduled task on the windows machines 
that'll fire off and rsync to the BSD box. No samba involved.

The naive might consider sharing out the relevant 
directories on the Windows machine, mounting them on the BSD 
machine, and then rsyncing locally. Unfortunately that 
involves pulling all of the files over the network and so 
rsync gains you nothing.

If you wish, you could install a full cygwin environment, 
including an ssh server, install rsync into that 
(http://optics.ph.unimelb.edu.au/help/rsync/), and have the 
BSD box do the reaching out via a cron job.

Re: [Samba] Samba, rsync and a newbie sorting it out...

2003-02-19 Thread Jon Niehof
Uh, not quite.  If you use rsync to only copy modified files and not all 
files after the first backup then you DO still get some benefit from 
rsync.
True.


I'm 
not sure what you mean by pulling all of the files over the network.
What I mean is that partial transfers of modified files, one 
of the main advantages of rsync, won't happen--e.g. 2MB file 
foo has minor change. When running rsync entirely on the BSD 
box, checksums are run across the entire 2MB of the local 
copy, then across the entire 2MB of the copy on the windows 
machine--which involves pulling the entire 2MB over.

That being said, I do much prefer your solution of using putty and ssh 
on the windows machine.  It is much cleaner.  ssh.com's clients could 
also be used for this and they are free for home use last time I 
looked.  Could be wrong.
I've been insanely happy with PuTTY; full-featured and 
completely unencumbered license-wise.

Re: [Samba] Samba:connection only works one time

using samba 2.2.5; security=server
connecting as user1 (user logged in on PC) works (12:28:55),
disconnecting and connecting as another user2 (not the user logged in on

(12:38:19).
It seems it works only once and never again after one time logged in as

My experience (and, based on feedback from the list, others'

security=domain if at all possible. Otherwise you'll have to

Re: [Samba] CUPS or LPRng?

2003-02-10 Thread Jon Niehof
Not only did it fix their issues, but it gives them a nice
web-based administration interface where they can delete jobs if one does
happen to get stuck.  Setup was much easier than I thought it would be and
definitely easier than LPRng if you haven't done work with lpd before.  We
were using HP Laserjet printers which were natively supported by CUPS.

As a counterexample I had a *hell* of a time getting CUPS 
going and the web interface still dies on me whenever I try 
to do anything from it. Now that it's configured though it's 
 been solid and reliable as long as I stick to command line.

CUPS really seems to be the wave of the future though and 
certainly a lot of the filter/driver support is centered on it.

Re: [Samba] Windows 2000 Terminal Server Environment

2003-02-03 Thread Jon Niehof
I am running Citrix Metaframe XP on Windows 2000 server and would like to
have the ability to access files on my AIX Unix server.  Are there any
issues with Samba in a Windows Terminal Server environment?


In addition to the suggestions already given:
1) Run the latest Samba 2.2.7a--there are some problems in 
2.2.5 with opening certain files (especially databases) over 
the samba share. This comes up rather dramatically in 
multi-user environments

2) Run at least SP2 on the terminal server. There were a few 
fixes (not all available as separate hotfixes) pertaining to 
multiple users on one terminal server having the same file 
open on the smb server--if one user closed the file, it was 
closed for all.

Otherwise I've been very happy with this configuration 
(although we're using Linux on the samba end).

set this in your share configuration

force group = users

Is there any way to force the group 
ownership of created files?

Also, is there any way to force file ownersip to a given user 
on newly created files?

You can also do this on the filesystem level by setting the 
UID or GID bits on a directory. Then all new files created 
in that directory will have the same owner or group, 
respectively, of the directory. Useful if you want different 
directories within a share to be handled differently.

Re: [Samba] is use rhosts = yes still supported?

2003-01-17 Thread Jon Niehof
It seems like the first call into authorise_login never
checks the rlogin (bails at checking for non-blank password
in check_user_equiv) and then drops into guest mode; there
is then a second call which *does* check (and successfully
finds the .rhosts entry) but by this point we're being a
guest so it doesn't do me any good :) I need to have it be
the same username as on the server to have permissions work
out properly.

Throwing in a few more DEBUG statements highlights the 
problem--for some reason the 2K server *never* passes down a 
username unless I use the share%username syntax. This works 
but doesn't exactly give me a warm fuzzy feeling as I'd 
rather have it handled by logged in username. For now though 
it does the job.

Why isn't there support for rhosts in security modes other 
than share?

Sounds about standard for security=server.  It's not a nice hack.  Make

Well, it's straight over a crossover cable between two

Samba 3.0 includes more protections for security=server, but it is still
fundamentally flawed.  Why can't you use 'security=domain'?


The 2K box isn't a domain controller, just standalone.

Yes, eventually we'll migrate to The Right Way to do it 
(domain) but for now I'm going for quick hack (thus the 
rhosts approach from the other end).

[Samba] security = server random failures

2003-01-15 Thread Jon Niehof
I have a Windows 2K SP2 terminal server and a Samba 2.2.7a 
server. The Samba server uses security=server with the 2K 
terminal server as the password server. Users log in to the 
terminal server and attempt to access (always the same) 
share on the Samba box. When there are no sessions open to 
the Samba server the connection from the terminal server 
always works; subsequent connections (with the first one 
open) fail about 70% of the time.

Log snippets (one success, followed by one failure, log 
level 1).

[2003/01/15 15:57:55, 1] smbd/service.c:make_connection(636)

I found in the mailing list archives the following tidbit 
from Andrew Bartlett, dated 13 Aug 2002:
Don't use 'security=server' when you have a real PDC. 
That's what security=domain is for.  Furthermore, due to 
bugs only (possilby) corrected in Win2k SP3 you must use 
Samba 2.2.5 or above, as the PDC will otherwise randomly 
refuse authenticaion.

Does this statement still apply to 2.2.7a? I'm loathe to 
install SP3 because of EULA concerns and, of course, 
throwing big chunks of patches into a production server.

Anything else that might make this work?
