samba - Jul 2005 - Shares all empty after upgrade to 3.0.14a-fc4

Hi,

Hoping you can help. I've updated my samba server (PDC) from 3.0.10 to
3.0.14a as part of updating from FC3 to FC4.

I now find I cant see inside any of the shares, even though  I can see
the share names themselves and the directories are quite readable to
Linux processes. So, e.g. I can see that I have a share "Users", but
not
the contents of it. With one exception all shares are empty/blank. The
exception is that my "tmp" share includes 1 "file" called
OSL_PIPE_500_SingleOfficeIPC_3d3cfaac9b18bd645001594325165, which of
course doesn't exist in the filesystem.

I have disabled selinux, checked the audit messages, checked all
permissions and ACLs I know of and can't find a reason. it happens in
both a winxp client and using kde smb:// in konqueror.

I have included a snippet of the log file for an smb:// read of my home
directory. It is just finishing enumerating the files in the directory,
but then seems to give up.

I've just found that if you enter an smb:// directory path that exists,
the log file shows that the correct directory is scanned, and I don't
get a client error : the client behaves as if the dir is empty. However
if I do the same thing in winxp, I do get a client error -- "Windows
cannot find "...path..."

What's happening?

Daniel,

I checked the smb.conf, and it did get changed. I don't know what changed it
as the install scripts in the samba rpm don't do so. The following items
were added:

client ntlmv2 auth = yes
restrict anonymous = no
client lanman auth = no
max protocol = NT
server signing = Auto

As you see it added "max protocol" and a few other lines which may
well have
messed things up. I already had max protocol=NT. I didn't expect this to
happen and it's rather annoying that it did so without notice...

Before your note arrived, I had decided to reinstall samba - save smb.conf,
smbpasswd, delete RPMs [1], reinstall from scratch, use SWAT to get basic
smb.conf running again. It worked fine, which suggests it was some
configuration thing.

Thanks for the suggestion, though

[1] rpm --erase didn't delete the manual pages...
