Problem with large files and smbclient -Tc

[Michael Collin Nielsen]

I'm trying to use smbclient and amanda to backup a win2000 server to my
tapestation which resides on a Sun450 running Solaris 2.7.

I've tryed with both 2.0.9 and 2.2.0 both gives me the following when
creating the backup tar file:

>smbclient  //windows2k.mydomain.dk/backup -U user%passwd -T c backup.tar
added interface .... [snip]

tar: dumped 33 files and directories
Total bytes written: 2281778176

which seems a bit odd, the \Backup.bkf file is reported to be
of size -2023426048k

When trying to restore the files  (to another win2000 server) I get the
following error:

>smbclient //another2k.mydomain.dk/restore -U user%passwd -T x backup.tar 
added interface... [snip]
Domain=[ARBEJDSGRUPPE] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager]

restore tar file \Backup.bkf of size -2023426048 bytes
checksums don't match 0 1633
abandoning restore, -1 from read tar header

Testing with GNU tar gives:
>gtar tvf backup.tar
drwxr-xr-x 0/0               0 2001-05-17 14:55 ./GHOST/
-rw-r--r-- 0/0          602893 1998-08-25 09:38 ./GHOST/GHOST.EXE
-rw-r--r-- 0/0            8092 2001-05-17 15:01 ./GHOST/SYSTEM.GHO

-rw-r--r-- 0/0      6566508544 2001-06-10 22:09 ./Backup.bkf
gtar: Unexpected EOF on archive file
gtar: Error is not recoverable: exiting now

the x option gives me approx the same:
>gtar xvf fildirektefrafc.tar 
./GHOST/
./GHOST/GHOST.EXE
./GHOST/SYSTEM.GHO
./GHOST.ERR
./FC1.GHO
./Backup.bkf
gtar: Unexpected EOF on archive file
gtar: Error exit delayed from previous errors

Does smbclient have a problem with files greater than 2G ? (the Backup.bfk
file is approx. 2,2G) I have seen some reports of that beeing the case,
but no workarounds or things that can get me out of this mess...

Anyone ?

Regards
