Description of problem:
After I experienced this problem, found the following in the 
URL I have included (I did not try patch myself):

> After the new samba install, I tried to "get" a file from Win2000 Advanced
> Server to Mandrake Linux 8.2 server using SMBCLIENT and was successfully
> able to transfer a 6.63GB file.  Then I tried to "put" a file from Mandrake
> Linux 8.2 server to the Win2000 Advanced Server and the file completed at
> 4GB rather than 6.63 GB.  Is this normal?

The following might be a fix to your problem :-)

How reproducible:
Didn't try

Steps to Reproduce:
1.connect to W2K Pro with smbclient 
2.put file >4GB


Actual Results:  Only 4GB gets written.

Expected Results:  Whole file gets written :-)

Additional info:

This was supposed to have been merged in samba 3.0 CVS?  But 
maybe the patch will work against 2.2.1a?

Comment 1 David Yerger 2003-01-11 21:14:14 UTC
Tried patch against 2.2.1a SRPM, did *not* work - now fails at 2GB instead of 4GB -

I am assured by our network admin that W2KSP3 has an 8GB filesize limit for
FAT32, not 4GB.  He is going to test.

Comment 2 David Yerger 2003-01-13 21:38:22 UTC
Tested with unpatched smbclient against a share on the (NT 4.0) server using
NTFS, also failed (this time simply locked up), so it's not the other end.

Comment 3 David Yerger 2003-01-14 11:38:40 UTC
Tested smbclient from samba 2_2 CVS, it includes this patch and *does* work.


So the patch seems only to work against later versions of samba than 2.2.1a.

I maybe could put together an RPM and attach it if you like. . . 

Comment 4 David Yerger 2003-01-24 22:33:53 UTC
I used

./configure \
	--prefix=/usr \
	--sysconfdir=/etc \
        --with-fhs \
        --with-privatedir=/usr/bin \
        --with-lockdir=/var/cache/samba \
        --with-swatdir=/usr/share/swat \
        --with-codepagedir=/usr/share/samba/codepages \
        --with-automount \
        --with-smbmount \
        --with-pam \
        --with-pam_smbpass \
        --with-mmap \
        --with-quotas \

(mostly stolen from the official SRPM's .spec file) to compile.

It calls itself 2.2.7pre1


Comment 5 David Yerger 2003-06-30 01:18:31 UTC
Still broke with smbclient from the samba-client package, version 2.2.7, 
release 3.7.2, April 6 2003 (bugfix from rhn overwrote my copy <groan>)
