step 1. make a new directory for later use
#mkdir /dos
step 2. mount use win98's partition to /dos
#mount /dev/hda1 /dos
notice: you must use root account to do it. now you
happy with your linux and win98.

Subject: Please help! Linux web server problem!
Date: Wed, 25 Aug 1999 20:49:20 GMT
Hello all!
I recently set up my Linux box as an Apache web server. I got a cable modem
package that grants me a few static IPs so I actually have a full time
connection to the internet.
Once Apache was set up and my DNS was running, I tried the server and it seemed
to work fine. I was able to get at my web server through the internet (using
the dial up connection I used to use before I got a cable modem). However,
when I asked a few friends to try out my server, they were unable to reach it.
I then started looking into the problem myself and, lo and behold, I was
unable to reach my server through my dial up connection. Well, I fiddled
around a bit and then rebooted the server. After rebooting everything was fine
again. I sent my friend a message telling him to try it again. Then I left it
alone. Well, about a half an hour later, I just thought I would check up on
the server and found that it was unreachable again.
So, this is where I am stumped. Every time I reboot the server, it is fine for
about 20 minutes and then it becomes unreachable. My only theories at this
point are 1) my cable modem service provider may use DHCP to provide me with my
static IPs in which case, when the lease is renewed on the IP, the server can't
deal with it or 2) I got something screwed up with my server.
Here's some specs just in case they are needed:
RedHat 6.0 using apache 1.3.6 (installed from the RedHat CD)
As far as I know, all of the appropriate domain records are in order and have
been active since a couple weeks ago.
Can anyone provide any insight into what kind of problem I could be having?
and what I can do to fix it?
Any help is appreciated.
Thanks
David

^^^^^^ I don't agree with the above. In all
Turing-complete models, e.g. a Turing Machine,
a Unlimited Register Machine, one crucial component
is potential infinity or unboundedness. E.g. a
Turing machine at any given moment in a computation
has a finite # of cells on the tape, but there
is no upper bound to how many we can add to the
tape if necessary. Similarly, with the Unlimited
Register Machine, a particular program only uses
a finite # of registers of the countably infinite
# of machine regs, BUT the contents of each
register is a unbounded natural #!!!! On a "real world"
machine, the contents of a memory cell or a register are
bounded!!! I.e. real machines are finite, i.e. cannot
handle unboundedness. Or to put anyway, we can have overflow.
Hence, I would say real machines are Turing-bounded!!
Regards,
Bill Halchin
Sorry, I saw later post where it said this should be in other
group but I wanted to correct what I see as a misunderstanding
of Turing complete.

Hi There!
I'm a newbie to mars, so I would appriciate any help on this.
I know that I can configure mars in /etc/nwserv.conf, but I badly need
some good tips, and

Yup, Linux will work quite well in such a setup. Most Linux distributions
don't include Netatalk, though, so you'll need to get it and install it
separately. (Netatalk is the most commonly-used Linux package for Mac
networking.) There are a couple of caveats:
1) Depending on just how old that "older model cheap pc" is and what you
want to do, you may find performance lacking. I wouldn't want to run
really massive disk-intensive stuff over a 10Mbps network connection to
a system with a five-year-old IDE hard disk, for instance.
2) Netatalk and Samba (Linux's Windows file sharing system) use different
methods for file locking, so having Mac and Windows users try to access
the same files at the same time can get ugly. Accessing the same files
at DIFFERENT times from these platforms isn't a problem, though.

Unless you're planning on prosecuting, I think it's almost a worthless
task. The most you might accomplish if you find the perpetrator is that
his ISP account would be taken away. So he'll just get an account with
another ISP and go on his merry way.
If you see something that looks like a concentrated attempt to gain
intrusion into commercially important systems, you might try harder to
track them down. It might be industrial espionage, rather than a random
script kiddie.

So pppd rejects that option. But it doesn't work since the ISP is now
configured wrongly.
You can complain to the ISP but it's not likely to do any good since
you run Linux. MS products must accept the 0.0.0.0 as the remote's IP
address or provide a real IP address for it.
You should be able to use a reserved IP address, say 192.168.0.1, with
pppd's IP addresses option in this way:
:192.168.0.1
to give the remote an IP address it can use as yours for the connection.
Note that your IP address for Internet connections is the one the ISP
gives you. The reserved address you give the remote will only be used
for the PPP interface at the remote.

Hi!
I just did a very stupid thing - I turned on inetd debugging and
rebooted my RH 5.2 Linux box
and now I can't log in. I get no logon screen, instead I get the
debugging info! Also, I can't ssh, telnet or ftp to it. Trying the
boot/rescue disk doesn't help. When using the latter it says
something that it can't create a console...
Any tips?

Subject: RedHat 6.0: rpc.mountd process grows and grows.
Date: Wed, 25 Aug 1999 13:35:44 -0500
We have a RedHat 6.0 machine (kernel 2.2.9) with 256MB RAM acting as an NFS
server, with moderate use from various NFS clients (Linux RH 6.0 and
NEXTSTEP primarily). After not too much time (say a day or two), the
rpc.mountd process grows to be VERY large, here's an example of an
rpc.mountd's process information (from top)after running for just 1 day:
PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU
%MEM TIME COMMAND
xxxx root 4 0 159M 143M 433 S 0 0.0
56.8 3:40 rpc.mountd
Eventually, this process grows and grows and eventually dies. At that time,
I have to restart the daemon. No apparent useful information seems to be
logged to /var/log/messages.
Is this expected behavior? Can anything be done?

Indeed, I should have been more precise: by 'elementary arithmetic'
I meant arithmetic on (arbitrary) natural numbers.
If everything is bounded, you just have a finite state automaton,
which certainly isn't Turing complete ;-)

You do have a floppy drive in your machine, don't you ;-)
As long as you swap floppies (and buy new ones) as required
by the program, that's all the unboundedness you need ...
