My friend and I have put together a nice newsletter about Internet ,phone
systems, Computer Security , Cryptography and about every aspect of computers
and phones. We are far from desperate for writers but we could still use them.
If
you would like to write an article about anything on computers or phones that
would be informing ,researched(meaning it is fact) , and topics that haven�t
been
killed , meaning there is already 293829 articles on it, we would be
interested. The name of our newsletter is Columbia 2032 or C2032 for short. You
can send all articles to [EMAIL PROTECTED] . We will review and add you
to our newsletter mailing list.

I'm running xntp3-5.93-4 rpm, which should be all you need. Its the one that
ships with RedHat.
Here is my /etc/ntp.conf file, which has been essentially unchanged for a long
time:
#
# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available. The
# default stratum is usually 3, but in this case we elect to use stratum
# 10. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator or
# another protocol, the prefer keyword would cause the local host to
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.
#
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
#
# Drift file. Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.
#
driftfile /etc/ntp/drift
multicastclient # listen on default 224.0.1.1
broadcastdelay 0.008
#
# Authentication delay. If you use, or plan to use someday, the
# authentication facility you should make the programs in the auth_stuff
# directory and figure out what this number should be on your machine.
#
authenticate no
#
# Keys file. If you want to diddle your server at run time, make a
# keys file (mode 600 for sure) and define the key number to be
# used for making requests.
#

trustedkey 12345
requestkey 12345

# Reference Sites -- check http://www.eecis.udel.edu/~mills/ntp/clock2.htm

peer 192.75.213.193 version 2 # xenitec.xenitec.on.ca # Ed Hew
Note that the local clock is set up as a stratum 10 server, NOT the default (and
wrong) RedHat value of startum 1. Check out the ntp home site for the current
list of available servers at each stratum, and be intelligent about some of the
local sites to peer with.
Does that help you?

What are your firewall rules?
Have you read through the PPTP Masq HOWTO at
ftp://ftp.rubyriver.com/pub/jhardin/masquerade/PPTP-howto/PPTP-Masquerade.h
tml ? It has a troubleshooting section.

Enable logging in named.boot file.

If you have bind 8.x things may be slightly different. Check the man
page.
After you have done this you'll see in /var/log/messages
when some of your machines have done lookup and what address it is for.
There are two possible causes of DNS lookup
1. MSIE
2. Something on your Linux machine which tries to resolve name or
address of your windows machine connecting to it.

I don't know how to do it with Windows 98, but with Windows 95 answer is

I think you need to go to opposite direction and create primary zone
for your local net. Set up both direct (name to address) and reverse
zones. Don't forget reverse zone for 127.in-addr.arpa (to resolve
localhost) and A record for localhost.your.domain in direct zone.
Thus most of your DNS requests would be resolved locally
without need to bring link up. If this doesn't help,
do following
1. Add IP address of some net portal into local named cache with very
large TTL.
2. Make this portal starting page for exploring internet on all
machines.
Thus any user starting exploring internet would get IP address of the
start page from local nameserver and his first packet outside would on
port 80 which would bring link up.

Subject: DNS working, yet more questions (Sedmail problem maybe?)
Date: Mon, 15 Feb 1999 20:59:07 GMT
I successfully configured dns and now I have web and ftp services. I
registered bigbrie.com for testing purposes. I have a demo webpage at
http://www.bigbrie.com and anonymous ftp at ftp://ftp.bigbrie.com. I
am having a couple problems with my mail server which I am not sure is
from the way DNS (BIND 8.?) is configured or from the way sendmail is
configured. I am using Slackware 3.6 which comes with Sendmail 8.9.1 .
First problem, I can email out of my machine, but when the recipient
recieves it, it puts the sender with the machine name appended (ie
from: [EMAIL PROTECTED]) . I would like it so the sender says
[EMAIL PROTECTED] . Is this a DNS or a Sendmail issue? How do I fix
it?
Second problem, If I go to send email to [EMAIL PROTECTED] and it gets
bounced with a relay error( included below). If you are more curious
about the error, send email to [EMAIL PROTECTED] and it should bounce.
If you send email to [EMAIL PROTECTED] it gets there. Of
course I want people to be able to send email to [EMAIL PROTECTED] .
Same question of course: Sendmail or DNS? The fix?
Please look over my DNS configuration (below). Do I have to have the
MX name the same name as the machine? It looks as if
mail.domainname.com is usually the name of the machine that is used
for mail. Of course everything is on one machine in my case. I have my
machine hostname named darkstar or darkstar.bigbrie.com

It looks familiar. I remember the couse of the problem in my case is that I change
the IP number of one Linux box from 192.168.1.2 to 192.168.2.2. The other box I
only did it partly. If you did changed you IP number somehow then grep the old IP
number in /etc directory and change them all to new number.

Subject: IP masquerading and socket timeouts
Date: Tue, 16 Feb 1999 01:52:36 GMT
First off, I'm using the Slackware 3.5 release with the kernel updated to
2.0.35. I'm using a Win95B machine and a Win98 machine as clients. The
Linux box is my gateway to the internet via PPP and IP masquerading (using
ipfwadm, ipautofw, and diald). Everything works great except for one thing.
If I perform an FTP transfer (on one of my clients) on a file that takes more
than a certain amount of time to complete (looks like about 15-20 mins), what
it boils down to is that something is shutting down the FTP control port
(port 21) during the transfer so that my clients can't notify the server (or
the server notify the clients, not sure which) that they received the file
okay. (In other words, WS_FTP says something like "Blocking call canceled".)
How can I change or remove this timeout? Or is it a bug that I just have to
live with?
If you need more information, please tell me which file(s) to post.
Thanks,
Bill

Subject: QMail questions
Date: Tue, 16 Feb 1999 01:48:53 GMT
Somehow or another I'm still nominally responsible
for operating this Linux box. This in spite of my
continued status as "bumbling newbie." =) Anyway...
We swapped Sendmail for qmail a while back. Something
to do with hackers, spammers, and etc. And I never
could get the alias bit of sendmail working properly
with the newer config files. (I initially followed
the instructions on the now defunct and non-maintained
"virtual-web" mini-HOWTO, with domainalias files and
Cw records and etc.)
So we tossed in qmail, which proved to be secure
and usable. However, we've never gotten .forward
files to work (even while using the proc+df rc file).
I noticed that dot-foward appears to be an executable
of some sort; where would I find it?
Also, for some reason 'root' has never gotten mail since
qmail was installed. I'm assuming there's probably some
alias lurking somewhere; any thoughts as to where I should
look? Many thanks in advance... I'm clueless on a command
line! (I'm a Mac user who's only CL experience was using
ProDOS on an Apple IIgs...)

You're confusing syntaxes here. Procmail uses Regular Expressions, which
have a different syntax than the filename wildcards used by the shell.
Take a look at "man procmailex" for examples, or the perl regular
expression manual page, or "man egrep".
To fix your examples, they should be:
:0:
* ^To:.*ppp
/usr/home/juergen/mail/Linux-PPP
:0:
* ^To:.*kde.*
/usr/home/juergen/mail/KDE

ppp-over-ssh imposes no more of a performance penalty than ppp-over-GRE,
which is what PPTP is. In fact, I wouldn't be at all surprised if
ppp-over-ssh performs a lot better than M$ PPTP - which in my experience is
pretty poor - does. Note, however, that there are licensing fees involved
with using ssh in a commercial setting.
There is the Linux PPTP project, which has a working tunnel implementation
and is just now getting MS-compatible encrypting and compressing pppd
patches. http://www.pdos.lcs.mit.edu/~cananian/Projects/PPTP/
There is also the Linux FreeS/WAN implementation of IPSEC and ISAKMP, if
you're not scared by beta-level software. http://www.xs4all.nl/~freeswan/

The pcnet32 driver is included with the standard kernel (2.0.35 at least).
It works with AMD PCNet32 PCI cards like the AT-2450.
Rebuild your kernel, or load it as a module.

It can be done in several ways. If you have another Linux system
on the net with a CD-ROM, you can install over Slackware with NFS.
Another way is to use floppies to install the A and N series,
enough to bring up networking, then use FTP to transfer the rest.
(I realize this is sketchy, but you did say you want to learn
about networking, right? Get through this, and you'll be an expert.)

A lot of these problems are covered in the ORL VNC faq. check there for
your specific problem. Which file/dir does not exist? What error are
you getting? Come on, we're good, but no psychic.
