True. I missed the point entirely.

Subject: samba and Windooz95 B (Ver 4.00.1111)
Date: Sun, 04 Jul 1999 02:30:48 GMT
Hi!
Am I the only one having troubles with this configuration????
I have two PCs, one w RH60/Win95A and one w SuSE61/Win95B
The RH60 istallation script for samba seems buggy: there is an entry
in the inetd.config file which I had to remove. so far, so good;
when running samba on the SuSE box I can connect from the W95A machine.
when running both machines on Linux, smbclient works fine for both;
but when trying to connect the RH6 samba with a Win95B box I receive only
"connection refused" errors.
tcpdump shows nothing strange - I just _can't_ talk to port 139 on the
Win95B box.
Any ideas what is going on????

Maybe it's the way that Windows and Samba do long filename
truncation? We had a small problem here when we moved over to
samba because we had batch files that ran from DOS shells that
would look for something like \\server\longfi~1 instead of just
"\\server\long filename", and when we went to samba it changed to
something along the lines of \\server\longf~ds...

After about 100 hours of reading and trying several
different "guaranteed-to-work" setups that have been
mentioned here and in other NG's - 'think' I'm close to
having a network that functions.
Here's what I'm seeing:
1) W95 box (192.168.0.2) "talking" like crazy, (can see
thru-put on hub)
2) Linux box (192.168.0.1) says Samba being a server at the
correct address (192.168.0.1)
3) can ping local loop, and linux box, fine
4) W95 box doesn't connect
5) [ifconfig] shows eth0 not active
6) [ifconfig -a] shows eth0 configured properly (?)
7) [ifconfig eth0 up] gives me resource not available.
SOooooo - what am I missing ??
(betting the answer makes me feel more ignorant)
Need to know why the network won't activate - do I need to
re-build the kernel ???

So you are saying that the choice of programming language is an
engineering issue, not a computer science issue?

Principles are ideas which explain something, or provide a reason to
do a thing one way rather than another (eg principle of least
privelege). Certainly principles could be determined from experience;
but I see no reason why they must be.
This from WordNet:
principle n 1: a basic generalization that is accepted as true and
that can be used as a basis for reasoning or conduct; "their
principles of composition characterized all their works" [syn: rule]
2: a rule or standard especially of good behavior: "a man of
principle"; "he will not violate his principles" 3: a basic truth or
law or assumption: "the principles of democracy" 4: a rule or law
concerning a natural phenomenon or the function of a mechanical
system: "the principle of the conservation of mass"; "the principle of
jet propulsion"; "the right-hand rule for inductive fields" [syn:
rule] 5: rule of personal conduct [syn: precept] 6: an explanation of
the working of some device in terms of laws of nature; "the principles
of internal-combusiton engines" [syn: rationale]
>Principles, divorced from experience, rot. If you want to understand
>good principles, the only trustworthy source is good code.
But why C++ code? The same principles found in the C++ language are
applied in other languages also.

I disagree. My reasons have been stated. You are saying something
analogous to this:
"if you want to know how a fuel injected engine works [-> the
principles behind it], you must study the engine in car {X}. Although
cars {Y} and {Z} have similar engines, studying them will not reveal
*any* of the principles used to design the engine of car {X}."

Subject: Cross-over cable between NT and Linux
Date: 03 Jul 1999 20:45:16 -0700
I hope this is a reasonable cross-post since I'm trying to connect a
Linux box to an NT box. This problem may well be due to some
deficiency in my general networking knowledge rather than my knowledge
of either OS. But maybe someone here can point me in the right
direction.
I'm trying to connect a Linux box to my NT notebook via a cross-wired
(cross-over, cross-patch, whatever you call it) ethernet
cable. (I.e. I have no hub.) As far as I can tell I have the ethernet
interfaces up on both boxes (ifconfig shows the right things and route
shows me what look like reasonable routes. I think.)
>From the Linux box:
eth0 Link encap:Ethernet HWaddr 00:10:4B:30:51:37

....
At any rate, can anyone give me any hints how to diagnose what's
actually going on? (One fear I have is that my cross-patch cable is
dorked up. I know I made it right because I've used it before but that
was a long time ago and it's conceivable that it's busted now. Is
there any easy way to check that?)
Apologies if this is not a very interesting question. Pointers to docs
are certainly welcome; I'll gladly RTFM if I can know what the right
FM is.

My Linux (RedHat v6.0 /w v2.2.10 kernel) box has 2 NICs, a PCI card and a
ISA card. I'm interested in determing the relative CPU time consumed by
each card. Is there a way to view the CPU time used in handling the
packets on a particular Ethernet interface?
Thank you.

I am wondering when using ipmasquerading would it be possible to
restrict the URL that a machine behind the ipmasquering machine
can have access to. What I mean is suppose I often see one of
the Win95 machine pointing his web browser to www.sexsite.com
and want to set my ipmasquerading so that the Win95 machine will
not be able to access to www.sexsite.com but still be able to
use www.netscape.com for example. But I only want to restrict
this particular machine. Can it be done?

Hi,
I have a interesting problem here.
I have two PC's at home. Both are running windows 98 right now. One
of them is connected to a @Home cable modem. To get access to
the net from the other machine, i've set up a LAN with 100Mbps
connection and I'm running WinGate software on both machine. So far,
they work like a charm.
I'm planning to install RH6.0 Linux on the one without direct cable
modem connection. I was wondering how can I gain access to the
internet from this machine with the other machine still running win98?
Is there any client side programs that can run on Linux but can talk
to a proxy server program running on win98?
Any help would be appreciated.
Thanks.
