Is there any help in reducing the read & write size? Down to 2048 (or
even 1024) may help.
(What is your setting? I belive solaris default to 8kb, is there any
sense in fiddling with that side, dont know.)

The ethernet-HOWTO have some info on a problem wich is the oposite as
yours, slow client, fast server:
4.4. Increasing NFS performance
Some people have found that using 8 bit cards in NFS clients causes
poorer than expected performance, when using 8kB (native Sun) NFS
packet size.
The possible reason for this could be due to the difference in on
board buffer size between the 8 bit and the 16 bit cards. The
maximum ethernet packet size is about 1500 bytes. Now that 8kB NFS
packet will arrive as about 6 back to back maximum size ethernet
packets. Both the 8 and 16 bit cards have no problem Rx'ing back to
back packets. The problem arises when the machine doesn't remove
the packets from the cards buffer in time, and the buffer overflows.
The fact that 8 bit cards take an extra ISA bus cycle per transfer
doesn't help either. What you can do if you have an 8 bit card is
either set the NFS transfer size to 2kB (or even 1kB), or try
increasing the ISA bus speed in order to get the card's buffer
cleared out faster. I have found that an old WD8003E card at 8MHz
(with no other system load) can keep up with a large receive at 2kB
NFS size, but not at 4kB, where performance was degraded by a factor
of three.
And the NFS-HOWTO... discuss it.

Any NE2000-compatibe network card will work with Linux. D-Link cards
also work rather well with Linux.

Hi,
I recently had trouble with my Samba and WinNT where the NT machine never
saw the Samba machine. I'm guessing this is your problem. To fix it, I:
* changed the samba settings to *not* have encrypted passwords
* modified the registry in WinNT as per
http://www.redhat.com/mirrors/LDP/HOWTO/SMB-HOWTO-6.html
* made sure my Samba server had a real IP (and ran the tests at
http://us2.samba.org/samba/docs/DIAGNOSIS.html)
Reboot the NT machine and it should work. It's tricky getting these guys to
work together but if you're patient, it will work eventually (and the payoff
is defnitely worth the headaches :).
Good luck,
Rick.

Since you've made it come down to your last words here, I'm compelled
to point out that your message has succeeded in simplifying things
_even more_ so than Bruce did. Furthermore, Bruce has some experience
with this matter, so he's not just talking in practice. So do I,
quite a lot in fact. Your comments are technically out of line.
I'm really surprised at your lax and clearly biased statements.
Let's revisit your statements:
>In theory, you're right.
In practice, this can be quite right too.
>In practice, C++ is a much more complex language.
This is not an in practice or not in practice thing, it's a reality:
C++ is more complex than C.
>As such, C++ compilers are much more complex beasts.
Probably. Something like that.
>And that is why some C++
>compilers do not generate as good code as the equivalent C compilers do.
NO, THAT IS NOT WHY. I cannot believe you are spreading such mythology.
Note too that many C++ compilers are also C compilers,
laced _right into_ the same exact compiler proper.
Let's see now. This MUST mean: some C compilers do not generate
as good code as themselves.
BTW, you are clearly comparing apples to oranges in your
_theoretical_ example. The reason why is because although we may
talk about equivalent C and C++ applications, it makes little sense
to talk about equivalent C and C++ compilers, certainly not at the
language level perspective itself. Clearly then this was either thrown
in as a red herring or is simply wrong do to poor wording or something.
The reason why some C++ compilers do not generate as good code as
some C compilers is the same reason why some C compilers do not generate
as good code as some C++ compilers, which turns out to be the same
reason why some C++ compilers do not generate as good code as some
other C++ compilers and also why some C compilers do not generate as good
code as some other C compilers. And that is because of the way the
authors wrote it. Now you may argue that C++ is so complex those
authors could not grok it. Well, this is not true across the board,
and no more so that some C compiler authors not grokking everything in C.
And anybody who thinks writing a C compiler is easy should spend the at
least 2 years or so it'll take to at least be baseline on a raw C compiler.
>In effect, what you're saying is "there is no theoretical reason why C++
>would be any slower than C". And you're right.
I can think of some theoretical reasons why C++ might be slower than
C in some areas. For instance, although a virtual function may be
faster than a hand-written switch statement, the comparison of say
exception handling vs some alternatives is not nearly so equivalent,
upon which C++ often would be slower in this isolated though granted
important area. But yes, this is true in practice for most of the
languages, and as some implementation show, true in reality too.
>But what others are saying is "a lot of existing C++ compilers generate
>worse code than a lot of existing C compilers". And they are right too.
Yes, see above. Perhaps those compiler writers just suck?
Or more to the point, perhaps the back end writers of the compiler just suck.
Anyway, clearly in your just made statement you are leaving open that
some C++ compilers generate better code than some C compilers.
So your remarks just don't follow.
>Sometimes theory matters. Sometimes it doesn't. The world is not as
>simple as you make it out to be.
You've made a grave technical mistake by assuming something more
complex must by nature have side-effects such as performance problems.
This is not inherent in complexity (though it is common).
Intuition is often wrong.

And additonally turning off pnp on the card. (for the 509b only).
And setting which port it uses, bnc(coax) or tp. for combo -cards,
it can be set by the driver, but if problems, set it in the card.
And make sure all cards connected run half duplex (normal) or full duplex.
(And while you are there, go to bios and set irq 11 and 12 to 'isa
only or 'legacy isa'. And turn off 'boot with pnp-os'. Just to
minimize what can go wrong..)
http://cesdis.gsfc.nasa.gov/linux/drivers/3c509.html
Only the IRQ and transceiver setting may be overridden when using
the river as a module. Setting two cards to 10base2/IRQ10 and
AUI/IRQ11 is done by using the xcvr and irq module options:
options 3c509 xcvr=3,3 irq=10,11
Available Transceiver Types
The available transceiver types are
0 default from EEPROM, normally 10baseT
1 AUI (DB15 connector)
2 undefined
3 10base2 (BNC)
4 10baseT only (RJ45 connector)
(Hmm.. from the above the line 'options 3c509 xcvr=3,3 irq=10,11' i
belive should have been 'options 3c509 xcvr=3,1 irq=10,11'...)

Hm.. I would have tried this first:
if coax:
alias eth0 3c509
alias eth1 3c509
options 3c509 xcvr=3,3 irq=10,11
or if tp:
alias eth0 3c509
alias eth1 3c509
options 3c509 xcvr=4,4 irq=10,11
or if tranceiver set in card, i guess:
alias eth0 3c509
alias eth1 3c509
options 3c509 irq=10,11
from the driver:
Known limitations: Because of the way 3c509 ISA detection
works it's difficult to predict a priori which of several
ISA-mode cards will be detected first.
.. so maybe a 'options 3c509 irq=11,10' will help.. (I dont know,
dont use modules.)

If driver _not_ in kernel. It does not make sense to have this in
lilo.

Maybe a new 3c509 driver into the kernel source, and compiling it into
the kernel. (to sort out problems if it is already solved in a new
driver, whats in 2.0.35 i dont know. to have it into the kernel will
save some trouble with modules, if that is what is happening.)
And remove any trace of loading the card as module.

With the card in the kernel it give information..
/var/log/dmesg is the file btw.
I dont know if it will work for you, but on a redhat 5.1 with 2.0.36
kernel; after a reboot, login as root, do nothing but; press ctrl and
the 'up-arrow'.
It takes me up to lilo boot-screen.

We agree (at least I do), it can be obscure et al indeed.
However, the alternative IS NOT as rosey as you make it out to be.
It is often as obscure and sometimes worse so.

Yes and no. Yes, in that what you say can be the case.
However, you are comparing things with what I'll call different
granularity levels. For instance, there is a dimension to templates
that I'll say is analogous to say the pointer alias rules in C,
which allow specific optimizations to occur. Knowing that some
templates came from the same generic descriptions DOES allow
certain shall we say global analysis to occur that either would
not be otherwise or at least very hard otherwise. This is distinctly
an efficiency issue. Also, I'll be hard pressed to have ever seen
the kinds of matrix ops Nathan is mentioning able to be done in C.
If Linus want to talk about theory and practice, well, this one's
practice for C :)

What you're describing does not make sense. If the host has an IP
address on 10.201.30.0/24, the only way it can reach 192.168.1.1 is via
a router on subnet 10.201.30.0, which would have to be 10.201.30.1.
Ditto for a host with an IP address on 192.168.1.0/25. Its can only
reach systems on the 192.168.1.0 network without going to a router on
the 192.168.1.0/25 subnetwork.
By definition, what you want must be happening as IP doesn't know any
other way to do it. To get the behavior you describe would require the
192 router to have a secondary address on 10... defined and configured.
Are you sure that you have set up the host addresses correctly or are
the hosts configured with both addresses on the same interface?
By the way, if what you are trying to provide is high reliability service
offerings accessed from the Internet, there are better ways to achieve
the goal. However, if all you want is better access out to the internet,
this is the easiest way to get it.

You can also get rid of WinGate.
Get Sygate 3.0 for Win9x/NT (www.sygate.com).
It's not a proxy but allows you to share your modem (thus network
connections).
>From your linux box you'll be able to telnet, HTTP, FTP, etc...
Plus Sygate can autodial for ya.
