win95 client problems (registry limitation?)
...dy:
I'm new to this samba stuff, but I've run across a problem that
doesn't seem to be documented anywhere.
It seems that OSR/2 clients (with all the M$ system updates; I
already added the EnableClearTextPassword key) that have had their
TCP/IP settings tweaked in the registry (eg, MaxMTU=576, TTL=32,
RWIN added, etc) for DUN connections have mucho problems with a
samba server on the LAN. Machines without the DUN tweaks work
great browsing their home directories, eg, right-clicking on files
to open them in an editor, etc. However, the machines with the DUN
mods have problems...

Dial in accounts (1883)
...can hazard a guess; I'll bet all your win95 clients have not had
all the MS updates (TCP/IP, network redirector, etc). Maybe some
are even win95a (pre-OSR/2). You should probably apply all the
currrent updates for OSR/2 networking stuff, and then apply the
same reg tweaks (TCP/IP stuff - MaxMTU, RWIN, etc) to all the
clients. Then you *may* get the same behavior...

Samba performance problem over a radio link.
...from an NT server on the 100MBit network provides 160KB/sec,
which is near the maximum performance.
I read through the on-line O'Reilly book about performance, and I
experimented a lot using mtuspeed410. However, I was unable to produce
any meaningful improvement. We tryied from 296 to 1500 as MaxMTU value,
and from 2x to 6x RWin. The best performance were obtained by 1152 MTU
and Rwin x4
Now I understand performance can greatly vary according to the settings
in the socket options, however, since experimenting can be a problem for
us (the network is in another town, and I have to make tests on...

SAMBA digest 1775
...in the registry, and then try adjusting (either
up or down). RWIN=3072 appears to be the threshold value
(according to the slow client stuff in the samba docs). In my
case, the default settings were fine for DUN performance, but I had
to bump up RWIN to get samba working. Original settings:
MaxMTU=576
MSS=536 (MTU-40 bytes)
RWIN=4xMSS=2144
New samba-friendly settings:
RWIN=8xMSS=4288
Now, not only does browsing work fine, but simple win32 apps
installed on the share work fine too. I can't help you with more
bloated apps like M$ Orifice (noun: a mouth or vent opening into

Slowdown when copying large files
I am currently investigating using samba on a Linux box to provide file
server services on our NT LAN (I'm a bit sick of NT doing dummy spits on
me). I'm running RH5.1, and have just upgraded samba to
samba-1.9.18p8-51.3 (using the rpm from
http://samba.anu.edu.au/samba/ftp/Binary_Packages/redhat/RPMS/5.1/samba-
1.9.18p8-51.3.i386.rpm)
The setup includes several NT servers, one set up as

tincctl patches
(Second try to send this. I wonder if the first one gotten eaten by a
spam filter; I'll link to patches instead of attaching them.)
Here are the tincctl patches I've been working on. They apply to
http://www.tinc-vpn.org/svn/tinc/branches/1.1@1545. I intend to commit
them once the crypto stuff's fixed. Since they're basically done, I'm
emailing them now for review and in case
