samba - Sep 2002 - How to bypass smbfs 2Gb limit without patching ?

Hello everyone,

I would like to send a big tar file (eg: >2Gbytes) from my Linux samba
server to a win2K client without patching the kernel.

Samba server: I'm using Linux version 2.4.8-26mdk (Mandrake Linux 8.1
2.96-0.62mdk) with samba 2.2.5-2.
I'm using tar (GNU tar) 1.13.22 to make the tar file and the command
"cp" to
copy this tar file to my win2k client. I've never tried smbtar.

smb.conf: I've enabled
	- socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
	- large readwrite = yes

Win2k client: It is not upgraded to Service Pack 2. It hasn't got disk
quotas set. It is formatted in FAT32. It has enough disk space =)

Problem: The file copy stops at about 2097 Mb !

A friend of mine tried to copy a file bigger than 2Gb (with dd if=/dev/null
of=/mnt/...) from his Linux version 2.4.18-10 (Red Hat Linux 7.3 2.96-110)
box, with samba-2.2.5-1, to the win2K client and he had the same problem.

I've heard that the culprit was smbfs because it doesn't support file
bigger
than 2Gb. I know there are patchs to this issue, but is there any way to
solve this problem without patching the system ?

I've never tried to patch my system as it is in production thus I'd
prefer a
smooth method.

Also,
I noticed that the copy of the files was taking a long time. I looked at the
size of packets with IPTraf and it showed very little packets tranfers. I
then used mcopy from the mtools and the size of the packets were much
bigger.

Thanks all for your kindness and support.

Why don't you just place the file in an acessible place and copy it from 
the Win2K side?

The other option is to use split adn copy file1+file2 bigfile

How very polite, Thank you.

smbfs is a client. If you are using smbfs then your win2k box is NOT a
client. To fix the smbfs limit you need to patch and rebuild the kernel.

Why fat32, btw? I'd assume it has a size limit much smaller than ntfs.
