Is that right? I believe the format is local:peer. So would this be something
like 192.168.0.25:some-reserved-ip-for-ppp? I don't have the docs in front of
me, but you should investigate the appropriate syntax for the IP addy
specification.

Here is a little program that uses cat without using the shell:
#include <unistd.h>
extern char **environ;
int main(int argc, char **argv) {
execve( "/bin/cat", argv, environ );
return 0;
}
It just does the same job as cat... It's really stupid and I agree in
all practical uses of cat you also need a shell.

The processes are KDE "helpers". KDE programs that use certain things
like dcop and arts will start them up. They did not die by themselves
in kde 2.0, but do with 2.1, a minute or so after you close the last
program that uses them.

I think Mandrake 7.2 is based off security implementations found in Red
Hat 7.0 (if not - don't gripe to me *grin* -- I'm just a developer).
Either way, check to see if you have a directory called /etc/xinetd.d --
this is where all your inetd services are configured at. A sample file
is the following:
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = yes
}
Do you notice in this file that disable = "yes"? If you wish to enable
telnet services, then simply edit this file (as root), change disable so
that it equals "no". THEN - restart the xinetd process. Hope that helps.

Subject: vfs problems
Date: Mon, 19 Mar 2001 17:38:00 +0100
Hi guys,
I have a question about the vfs interna. I have to write an excerpt about
it. But one thing I dont understand.
When a filesystem is mounted and I want to modify a file on it. The first
thing, vfs does is to look if the right VFS Inode is already in the VFS
Inode Cache.
Okay, here's my first problem: I have found something about the VFS Inode
structure. But if I want to read a file because of some commands , I usually
reference it by its filename and not by its Inode number. But in the VFS
Inode there is no field for the name of the file it represents. So, how does
the VFS know, which Inode in the VFS Cache stands for the file? Is there any
table maintained by the vfs for each mounted filesystem which points the
Inode-numbers to the filenames?
And then I have a second problem: if i have found the rigth Inode for the
file in the VFS Inode Cache, e.g. for a file in a VFAT partition. How is the
file entered? I dont think that there is a pointer to the blocks of the file
in the filesystem. I think it goes to the VFS Superblock and uses the
specific Superblock operations.
But I still don't know what the relation is betwenn the VFS Inode and the
real file.
Perhaps somebody can help me.
I'm really confused.
Thanks in advance.
Michael

This may sound stupid, but it's for testing purposes. Which running process
on a RH 6.2 server install can be "killed" to initiate a relatively safe
kernel crash and hang the system? I'm testing the capability of initiating
an automatic system reboot if the kernel becomes unstable or the system
crashes.

I run DSL through earthlink/Verizon. PPPOE, RH 7, No problems. The
configuration of PPPOE is a snap. I've been up and connected
continuously for 17 days.
But unless you have a dual boot with Win 9x or another machine with
Win on it, you'll have some problems with tech support if ever you
run into problems. They don't support linux and most of those people
know only Windows.
I do have such a set up, so when the card at the local office went
out about a month ago I just booted into windows and started calling
the support offices. They'd have me run through their various drills
in Windows and once Verizon replaced the card I just booted back
into Linux. Badda bing, Badda boom!

Sorry, but Linux is not designed to became unstable or even crash, I never saw
this happen in years, only if your hw is faulty/your power supply/USV go down or
you mucked
the system up dreadful, Linux will crash and in this case your automatic system
reboot wont help.
There is a kernel compile option:

Then you should be well able to write you own module that does a memcpy of
1024 bytes from adress 0 to address 4GB, and insmod it!
But if you want to "hang the system", suspending init should be
interesting (rememember to kill inetd and all other sevices beforehand).

I'm trying to install XFree86 4.0.2 for Zipslack, which is running off a
Win98 partition, but the installer script doesn't seem to be able to find
the files. I have noticed, however, that despite starting with capital
letters when displayed in windoze, the downloaded files are showing up
entirely in lower-case under linux. It seems the install script wants
Xbin.tgz etc. and just ignores xbin.tgz (infact the script wouldn't work at
all - until I entered "sh xinstall.sh", instead of "sh Xinstall.sh", as per
the docs).
Any ideas why this might be happening and how I might get round it?
Thanks,
Dave.

This overstates things a mite. If you're using the IDE-SCSI emulation
mode, and kill (say) a CD writing session, the SCSI "pseudo-bus" can
get confused enough that the system can and will "hang."
I would certainly agree that a _software-based_ "auto reboot" scheme
is not likely to fly terribly well; if the system is hosed enough that
user space stuff is halted, it is unlikely that there will be enough
there for the "auto reboot."
On the other hand, a hardware "watchdog" would be entirely sensible to
try out.
There's kernel support for this; basically, you create /dev/watchdog,
and set up a daemon that writes to that file once per minute.
(Probably somewhat more often than that to prevent any momentary
Unfortunate Pauses from leading to a reboot...)
The hardware side accepts a signal from /dev/watchdog, and basically
resets the timer count every time. If the timer reaches 1 minute (or,
probably, some other configurable schedule), the computer is switched
off and on again.
Methinks the best way of getting a "crash" would be to pick from:
a) Killing the watchdog daemon
b) shutdown -h now
