Enable the WINS server portion of Samba. It will build a common namespace
from all of the visible subnets and respond to queries.

You probably don't need IPX enabled in your Win9X machines unless you also
have a Novell server. In fact, leaving the IPX enabled needlessly causes
a well known problem where the Win9X machines momentarily pause for
several half-seconds every few minutes.

as root via both telnet and X (X both local and network). When I try I

Subject: Linux distributions for diskless nodes
Date: Fri, 02 Jul 1999 05:40:40 GMT
I've been working on setting up a few diskless nodes to run as a MOSIX
cluster. This has been a pain; I ended up browsing through the list of
mini-distributions on freshmeat's appindex and eventually settled on
CClinux, which I managed to eventually bludgeon into working. My
question is, is there a mini-distribution out there specifically
targeted at providing an NFS-mountable filesystem for X-terminals or
cluster nodes or the like? If not, can anyone recommend one that would
be easiest to modify to be suitable for root-over-NFS?

Subject: packet forwarding problem
Date: Fri, 02 Jul 1999 05:41:23 GMT
I have a SOHO network on 10base2. I use Slack 4.0 as a router/firewall with
two NIC's, one on the lan and one to a cable modem. All the other machines
are Win98 with 192.168.0.X addresses and one NT4.0 machine with a real
registered IP address. ipchains works fine, or at least it seems to. Here
is the forward chain (bob.issnet is the NT box):
Chain forward (policy DENY):
target prot opt source destination ports
ACCEPT all ------ bob.issnet anywhere n/a
ACCEPT all ------ anywhere bob.issnet n/a
ACCEPT all ------ 192.168.0.0/24 192.168.0.0/24 n/a
MASQ all ------ 192.168.0.0/24 anywhere n/a
I also have a static route to send packets to bob that may come from
anywhere. The 98/NT boxes have the Linux box as there default gateway. I
have an lmhosts file on all machines. Samba is NOT running on the Linux
box.
The problem
If I use copy (using the NT command line copy command) from one of the W98
machines to the NT machine, I get verify errors. The errors are only for
binary files and the error seems to be the insertion of a few extra null
bytes. This is not a disk problem since I noticed the problem during the
verify pass of a tape backup. If I reset the IP address of the NTW box to a
192.168 address, the errors seem to go away. If I add a static route to the
NT box to bypass the Linux router, then the errors also seem to go away. Is
there some sort of problem with my ipchains setup that would cause problems
with Windows networking?
Thanks,
Neil Marko

That is correct. I spoke with Scott Dudley (the guy who wrote Maximus)
about it about a year ago, and told him that I wanted to do something like
a Linux port of Maximus. Scott has essentially stopped working on Max
because he feels that the world has gone beyond BBSes. Scott had, at one
point some time around 1992 or 1993, offered me the source code for Max so
that I could port it to Linux. I didn't take it at that time, although I
wish that I had.
Bob Juge, who has Scott's ear and who happens to be a customer of mine,
has told me that he has suggested that Scott declare the product
commercially dead and release the source for Max to everyone. So far, it
hasn't happened. We shall see. (Who knows. Perhaps I shall respond to
the email he wrote me.)

Right, but you called the macro/function inc. Maybe it would be more
obvious if the function were named increment?
template<class T>
inline T& increment(T& x) {
return ++x;
}
Is there any question as to whether increment(y) changes the value of y?

You mean the lack of "ad hoc" polymorphism?
That's true in a pure Hindley-Milner type system.
However, Haskell adds "type classes", which allows a kind
of ad hoc polymorphism, but in a more structured (and type-safe) way.
By the way, how would you express with C++ templates the type
of the "error" function in Haskell:
error :: String -> a

Reply-To: [EMAIL PROTECTED]
Hi,
I am planning to install RH linux 5.2 onto my P166 Hitachi laptop,
which serves as a server for my LAN. 2 reasons of doing that. 1. It is
the most powerful PC among all my PCs. 2. I travel once in awhile, and
hence I need to connect to a different network.
Things that I wanna setup are: network connection, PPP, IP Masq &
Email.
My laptop specs:
Hitachi P166 MMX, 64 MB, build-in sound card, build in modem, build-in
10BT nic, 3.5" drive, and CD-ROM (build-in)
Anyone has any experience on setting up RH linux on l/top? Any advice or
precaution I should be aware of? Appreciate any info. Thanks.
Rgds,

Now, why would you wanna do that??
In Win98 (i.e. in the GUI) you can map a network drive (right-click network
neighborhood, click map networkdrive) X to a path.
In DOS mode, you are not logged on to a domain yet, so you won't be able to
access your network sources. I am not sure if there is a 'net' command to
log on to a domain.

from /usr/src/linux-2.2.9/include/asm-386/system.h, line 193:
#define save_flags(x) ((x)=__global_save_flags())
This is used at zillions of places in the linux kernel. And it is just
one example of such a macrodefinitions. It just goes to show that you
have to apply things like this judiciously, but you can live very well
with them.
It looks like you need programers who are better than mediocre to get
away with the above :-)

Date: Fri, 2 Jul 1999 02:25:49 -0500
I've had no luch with the other Linux use-groups; perhaps someone here will
be a little kinder...
I just switched from Win 98 to RedHat 5.1 and I'm having a hell of a time
with my ISP. Under Windows, the process of logging on was completely
automated, but I can't figure out what I need to do under Linux. First I
need to explain that if I dialed in to my ISP (under Windows) with the
'bring up terminal window after dialing' option checked, the terminal would
come up but I couldn't communicate with their machine; I would never get a
command prompt. If I then just went ahead and hit 'continue' or whatever
then Windows would do some stuff I would somehow end up online.
Under Linux, I can duplicate the terminal-without-a-command-prompt part with
minicom but I can't get that second, mysterious logon part to work. Again,
under Windows it was automated so I have no idea what was going on. I'd
really appreciate some help with this as I can't do any of the cool stuff
that I want to do (update kernel, download GNOME and KDE, or figure out how
to use my damn USB mouse with X) until I get my Linux system to go online.
Thanks in advance,
Daniel

Well, My problem is solved. I bought a gun. :) Not really. I want to
thank everyone for the help easpecially Mr. Smirnov. Apparently the
ethernet card didn't like the resources autoprobe found for it. I
recompiled the kernel with 3c509 support built-in and manually specified
the proper irq and ioports in an 'append' statement in /etc/lilo.conf
and reinstalled lilo. Now it is all working. I am still confused why the
interface came up and appeared to be able to send packets with the wrong
IRQ being used. I can't understand why it would send but not recieve. Oh
well, on to samba and ip masquerading....

No, not every C++ program is compiled to a finite amount of assembly.
Take the following counter-example:
================begin code==================
template <class A>
void call_me(A a, int i)
{
if (i > 0)
call_me(&a, i - 1);
}
int main(void)
{
int a;
call_me(a, 10);
return 0;
}
=================end code==================
This produces the following error message (with gcc):
test.cc:5: virtual memory exhausted
I guess that an infinite amount of processing time and
memory space would be sufficient to compile this program
Note that the program, once compiled, would actually terminate
after 10 recursive calls of call_me().
Also note that a *compiler* that can handle all possible variations
on this theme would need to be more than Turing complete.

Stephan

Reading the Q's and A's, my conclusion is that you connect to your ISP, get a
(dynamic?) IP address, but then you don't set a route to it. Once the
connection is established, type 'route' and check if there is a route to the
internet. Most likely you have to add a line like "route add default dev
kppp0" to your ip-up.local script.
