It appears that Linux 1.0 (Slackware 1.2.0) comes configured with IP Forwarding
turned on by default.  This is unfortionately wreaking havok with our routers
and right now I'm running without an ethernet port.

How does one turn IP Forwarding off?  I'd imagine that it's something that 
might need changes to one(or more) .c or .h files & recompiling the kernel,
but havn't been able to figure out exactly where.  Any assistance would 
be greatly appreciated, here or via mail.  Will summarize results.

I have a (simple) question ...

Hi Linuxers,

I have just tried to mount my home directory from my Linux box 
(Slackware 1.2.0) on a SUN running Solaris 2.3 with success but 
every time I "touch" the mounted directory I get this message on
the console of SUN:

What the heck is this?

This is a feature of the new e2fsck (version 0.5 ???)
After 20 times of mounting a partition this Filesystemcheck is forced.
This gives the System more "safetyness".

Subject: DX4/100 vs. pentium _VLB_ benchmark results?
Date: 4 May 1994 14:25:36 GMT

I will have to do some computing intensive stuff (analog circuit
simulation with spice3) in the near future. Therefor I consider to
get a new motherboard for my linux box, which is presently
a 486/33 ISA with 20 MB.

I dont want to get a PCI board because my SIMMS will not fit in there :-(.
So the alternative is either

a) 486/DX100 VLB   or

b) pentium P60/66/(90?) VLB.

I wonder if my 80ns SIMMS would be the bottleneck in a >33Mhz system.
Which is the best price/performance decision here?

Have some people who work for Novell or USL written ANY of the kernel code

If so how much?  If this has happened Novell could claim that the work of
their employees in their spare time has used information/ideas from work or
that it owns the copyright on any of their employee's work if it related to

I think it does in New Zealand, we could be in for serious trouble.

Linus, if you hear this, do you have any comment.

Subject: Stack overflow crashes Linux?
Date: 28 Apr 1994 02:08:09 GMT

        I was curious about how large a stack could grow under Linux 
and tried the folowing program, as a normal user (not root):

#include <stdio.h>

int recurs(int i)
{
        if ((i % 100) == 0)
                printf("\nRecursao nivel %d", i);
        return (recurs(i+1));
}

void main(void)
{
        recurs(1);
}
        and my machine simply stopped responding after some 16 mgs of stack
has been alocated. Could a normal user + bad programer crash a Linux 
system only letting the stack grow indefinitely? How fix this?

Indeed, he should probably shut up on that topic.  We are happily running
a whole Hospital on SCO, doing things Linux can not possibly do now; like
multiprocessing, multithreaded drivers, commercial software support,
sophisticated platform support, REAL MS-"DOS" emulation through Merge, etc.

Similarly problem here, except my printer is a dot matrix printer.
One thing different is that I could use cat file > /dev/lp1
While the printer is on LPT1, it should be /dev/lp0 instead, isn't it?

Please reply here.

[grotesque numbers of quotes deleted to save bandwidth and money]

Also make sure that you don't have PLIP enabled. It will cause rather
obvious problems with printing to a parallel port. 

Also, the suggestion to compile parallel printer support into the kernel is
valid.

A suggestion to whomever manages to maintain this portion of the code:

(1) State the above facts in the FAQ somewhere. It has come up a _lot_.

(2) Instead of saying "no such device" (to which a "ls /dev/lp0" yields a
"but the device _does_ exist" response), perhaps a way of determining what
support has been compiled into the kernel, callable with some function from
C, so that programs like LPR can be a bit more intelligent and report "no
parallel support enabled" instead of just shoving it in the queue and
waiting. It could be a long wait.

Also, when you get done reconfiguring the kernel, make sure you delete from
the queue (with lpc) the jobs that you added while the printer didn't exist,
especially if you tried it a bunch of times. That queue isn't a "it goes
away when you reboot" thing, and it _will_ try to print them. Check the man
page for lpc, and also type "help" when you are in lpc command mode.

Hi all, I have installed the package which got developed by "swen" at
ftp.uni-paderborn.de.

I can read every yp database, passwd, services, hosts etc. etc. but
e have the following problem:

1. If we omit the line +:*:0:0::: in passwd file, each user of yp
database can login to my host anyway (simply editing the ~/.rhosts
file...) ; YP seems to ignore completely the entry.

2. So, we can not use the netgroup system to filter access of untrusted users.
In other words, i would like to use an entry like:

+@admin_users:
+::*:*:*::/bin/false


Can anyone help us?

A DX4/100 is still accessing memory as a 25 Mhz 486.
I am still looking for a DX2/100, which would access memory as a 50 Mhz 486...
