You want disturbing ?

On my Samba 3.2.2 server I cd to a directory that is shared out as some
share named "share" :

# pwd
/opt/winshare/test_stuff
# echo "foo" > con
# chown smbtest:samba con
# ls -l con
-rw-r--r--   1 smbtest  samba          4 Sep  4 12:08 con

Back at my 64-bit Windows Vista ( Business Edition ) machine I see :

Microsoft Windows [Version 6.0.6000]

C:\Users\dclarke>net view \\FOSSIL

Samba 3.2.2

ultra       Disk           external seagate
The command completed successfully.


Is the Samba server running fine and doing what it should?
Yes it is :

# /opt/csw/bin/smbstatus

So let's take a look at that new file called "con" on that share :

C:\Users\dclarke>dir \\FOSSIL\share\test_stuff\
 Volume in drive \\FOSSIL\share is share
 Volume Serial Number is 09FC-04E7

 Directory of \\FOSSIL\share\test_stuff

See a funny looking file ( CSHOFG~F ) there ?  It sure is not named "con"
now is it? How did the name change?  Did the name change ?

Let's go look at the Samba server :

# pwd
/opt/winshare/test_stuff
# ls -l
total 23452
-rwxr--r--   1 smbtest  samba    2970312 Nov 18  2007 817-5093.pdf

Well golly gee .. the file named "con" is still there on the Samba server
and it looks fine but Vista can not see it and will not deal with it.

Must be a bug in Samba ?

Not bloody likely.

You should look on your Samba server to see if there are funny looking
three letter files named "con" or "com" or such.
