Domain=[WORKGROUP] NativeOS=[Windows 4.0] NativeLanMan=[Windows 4.0]
My Notes
--------
The domains are different,
which may interfere. Infernix,
they are really the same machine,
aren't they?
[ Yes, I set my domain to Workgroup in both Windows 98 and Windows 2000.
However, since Windows 2000 cannot login to the Samba domain (This is not
supported in the regular branch of Samba, only in TNG, as you probably know)
the Windows 2000 machine logs in to its own local domain which it calls
INFERNIX, the machinename. ]

infernix is the win2k
infernix2 is nt 4.0
[ No, infernix is Windows 98 and infernix2 is Windows 2000. In windows 2000
i use ip address .21 and in Windows 98 i use .17. Mind you, I am still
talking about the same machine here! Both Windows 98 and Windows 2000 run on
the same machine because I dual boot them. ]

Win2k is about to open (create?) the
file, at 28 seconds into the log, NT 4 just
opened it, 21 seconds into the log.
At this point, win2k goes into a loop doing oplocks 4 times:

Anyone know if this indicates a problem?
It **looks** like its restarting, but there isn't enough
info to tell me...
NT 4.0 is similar, but the start value keeps increasing,
which isn't a threatening (;-))

Conclusion: win2k is slow, but I don't yet know why. Anyone here
able to comment?

All this has not helped much yet. I really think that there is a serious
problem with either how Samba talks to Windows 2000 or how Windows 2000
talks to Samba (which might still be solvable on just the client or just the
server).
I didn't really mind that there was no solid solution yet, but now that I am
experiencing the same slow transfers at work and on my freshly installed
server, I am beginning to wonder what on earth is going on here. Regarding
my smb.conf, here are the options which I think might be relevant:
[global]
socket options = TCP_NODELAY
# using any of IPTOS_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192 didnt have any
effect.
[mp3]
fstype = "FAT"
oplocks = true
level2 oplocks = true
I have plenty options to test further, by either using tcpdump or more log
dumps. The log dumps are available at
http://www.infernix.nl/samba/sambalogs.infernix.tgz if you need more info.
Please, try to look further into this. I have no idea how or why this is
happening, but for me it has grown out to be a real problem, since we are
planning a migration to Windows 2000 clients at work, and i _really_ can't
tell my boss that this is all the speed we can expect ;(
Thank you in advance.
Yours sincerely,
infernix
