[Samba] samba + MacOS X

[Philip Edelbrock]

Sorry, let me back up a little: I may have not answered your original 
question.

The file sizes shown in OS-X are guessed 'physical' sizes.  If you 'get 
info' (command-i) on a file, it will show you the actual file size in 
parentheses.  The size in parentheses is what counts for most uses (like 
copying or CD burning).  It looks like OS-X (or is this Samba?) is using 
the wrong block size (256k?) to calculate the total physical file size.

Here's a sample file I have on my server (remember that Mac's actually 
have two seperate files on the server for both data and resource forks):

[root at drtheopolis raid]# stat adobejs.txt
  File: "adobejs.txt"
  Size: 364             Blocks: 8          IO Block: 4096   Regular File
Device: 901h/2305d      Inode: 60          Links: 1   
Access: (0666/-rw-rw-rw-)  Uid: (  501/    edge)   Gid: (  501/    edge)
Access: Wed Jul  2 11:58:33 2003

[root at drtheopolis raid]# stat ._adobejs.txt
  File: "._adobejs.txt"
  Size: 1536            Blocks: 8          IO Block: 4096   Regular File
Device: 901h/2305d      Inode: 61          Links: 1   
Access: (0666/-rw-rw-rw-)  Uid: (  501/    edge)   Gid: (  501/    edge)
Access: Wed Sep 24 15:35:14 2003

It seems like it should say that it takes up 8K in harddrive space and 
not 1MB.  Does anyone know where this conversion get mangled?

In any case, when I copy this file to the Mac, it suddenly 'shrinks' to 
the appropriate physical size of 8k (presumably because my local HD also 
has block sizes of 4K).

Regarding your other question, Baltra is a patch for Netatalk which 
makes Netatalk store/access files in an OS-X style (vs. the proprietary 
way Netatalk does).  It does UTF8 encoding using the 'iconv' library (I 
think Samba uses the same lib).  That way the file names actually look 
the same for everyone (including Windows folks) and the resource forks 
are preserved regardless of whether you use SMB or AFP (or NFS for that 
matter).  You can get more info on it here:

It's been 'beta' for a long time because there haven't been many changes 
or complaints.  From my experience, it's been stable, but it's always a 
use-at-your-own-risk thing.
