Hello, I'm having a problem copying large amounts of data from our Win2k3 server to a samba share on the samba server. I've turned debugging on in the smb.conf file all the way up to level 10 and I still do not see what is causing my file transfers to abort. It consistently aborts copying files as small as 10 gigs even. I've read through the performance tuning section in the handbook and tried those options, but I'm still not having any luck. I tried copying the same data using ftp instead and did not have any problems so I do not think there is a physical networking problem. If anyone has any suggestions I would greatly appreciate them. Kind regards, Elvar

I can run ntbackup to a share on another random WinXP or 2K workstation just fine without problems. The size of the backup I used in my test was 50G in size. Just to try and change things up I removed FreeBSD as the host OS for the samba box and installed gentoo linux with the same smb.conf hoping that maybe for some insane reason it was an OS problem. Negative, the same exact problem is still happening. Large transfers or even transfers that are large consisting of many files will fail at random times. It rarely ever lasts longer than 10 mins, sometimes 5. Again, I don't thin it's the hardware to the samba box because I can ftp 50G's across just fine. If anyone has any ideas I would really appreciate some assistance. Thanks, Elvar

NTbackup can write an 82gb file to the samba box, but I cannot copy it back to the Windows 2000 server to put it on an external drive to take it off-site. It doesn't happen between two win2k servers, and if I mount the samba share on another linux server, it also doesn't happen. But it happens between windows and samba, which leads me to believe it's an interoperability issue of sorts. I've updated the kernel, the network card driver (tg3 for a broadcom gigabit) as well as samba. Something else I notice, is if I copy via the samba server's onboard crappy 100mbit network, the problem doesn't occur. So I wonder if there's a transfer setting of sort that causes problems at high transfer rates that needs to be backed off a bit? Thanks Hans
