Subject: nnrp.access and dynamic IP: no security
Date: Sat, 27 Mar 1999 10:58:34 -0500
Hello,
I have already set up a news server (with the little help from my friends)
for my intranet. Everybody is happy with it and it's working fine. I'm not
receiving newsfeeds from any other host or feeding anybody. Just local news.
The problem arises when I had to add several computers located in a
different campus whose IP addresses are assigned dynamically.
I set up the nnrp.access like this
# deafult to no access
*:: -no- : -no- :!*
#
*.my.domain:Read Post:::*
But they're still able to connect (what means that everybody in the world is
able to connect) I tried to set up an entry for their domain like:
#allow remote users
*.their.domain:Read Post:::*
But it won't work anyways, since apparently the server identifies those
remote computers as belonging to their ISP domain.
But anyways, they're able to connect and read and post and they're suppose
not to, since there's no match for them in the nnrp.access
Any clue?
Please let me know what to do regarding this problem. Any help would be
greatly appreciated.
My news server is wet and wide open in the middle of the internet.

I am new to Linux.
I have two computers, one for Windows95, the other for Linux. I have Intel
EtherExpress Pro 10+ cards on both computers, and linked with RJ45. I know
my LAN works.
I want to know how to setup the Linux machine so that I can share files
between the computers. I am running Slackware 3.6.
Thank you in advance.

change this.
For the benefit of other users, here is the solution, provided by a

The data is nothing but static HTML or media -- very cachable. It's the
*volume* of data that's the problem -- there is simply too much of it to
reside on any single machine, which means some sort of lookup involved in
figuring out which backend box to proxy for. The structure of the data is
essentially several million directories, all residing under a common "root"
(in actuality, there are several layers of hashing going on, but the logical
structure is that described).

Well, the proxies would have to be behind *some* load balancing harware (they
all must answer requests sent to a single IP address).

There is no CGI on the system in question.

Unfortunately, Squid dies a horrible death under heavy load, and the ICMP
"cache-sharing" protocol it claims to have is complete bunk. We tried that
solution several months ago, and it is (unfortunately) unworkable in this
scenario.
I really don't think there's any way around the problem except to develop a
custom proxy. Nobody else seems to be pushing anywhere near as much data as
this site is, and so none of the 'standard' proxy solutions are up to par.

I've used a regestry file to make win98 to send plain text passwords.
Is there any way to change back to encrytp passwords with win98?
And will linux / samba with this:

Subject: Re: Finding a process on a port
Date: Sat, 27 Mar 1999 17:13:34 GMT
Hey splash!! I found a program that will do this: lsof -- that is, "list
open files". Since a socket is a file, you can figure out what process is
listening to which port. I found some rpms at
ftp://linux.sarang.net/pub/alzza-5.2/i386/RedHat/RPMS/lsof-4.40-1.i386.rpm
The syntax you use is: 'lsof -i :<port>' The program does a lot more than
this since it will figure out which process has any file open, and according
to the man pages it is available for several platforms. The source is also
at the same site (somewhere). Wouldn't you know that I'd find it right after
asking for it. Pain in the arse...

Just use a cheap hub and place it somewhere in the middle. (Some companies
sell very cheap 5 ports hubs)
Do not worry about (late)collisions because that will only be a problem if
the total cable length exceeds 5km (maybe a little less if you have some
delaying equipment in the line)
If you're planning to only use 2 computers a hub will even be faster then a
switch.

Well I also had this problem getting my external modem to work. It
seems like the pulldown menu and book for SuSE Linux 6.0 uses these
device names for the serial port. I had an old Unix book laying
around and it refered to the serial ports as 'cua0, cua1'. When I
manually edited the /etc/rc.config file to use the Unix device name
the serial port responded the first time.

Success! I followed the directions in ENCRYPTION.txt to enable encryption on
samba and it works I can see the contents of the root directory on NT.
Thanks to all.
ps To other Linux, NT and networking newbies out there: a pretty good book
on all this is "Linux Network Toolkit" by Paul Sery. It walks you trough
building a simple Linux Server and W95 client network. Unfortunately it was
written before windows switched to encryption.

Sure. There are two things you should try to do seperately. In
/etc/suseppp/scripts
you will find a script ppp-up. Try to get this to work. Once you're
able to initiate a ppp-connection using this script (and cancel it
using ppp-down), your halfway there.
Next you need to set up diald. diald is started (on reboot) by
calling /sbin/init.d/diald, which is easy to change to connect using
one of your scripts in /etc/suseppp.
However, by default diald will use /etc/diald.conf, so you might want
to change this for your purposes --- the manpages give really good
examples on how to do it. Be aware that you might need to change
/sbin/init.d/diald to reflect your use of the standard-setup (which is
non-standard under SuSE).
This should get you on your way

And if it doesn't, your script should look something like
"" 'ATZ'
^
'CONNECT' ""
^
(note the "" instead of ") and
'ogin:' 'myusername'
'ssword:' 'mypassword'

Disclaimer: this is my humble opinion; it is possible to set it up
with more or less, so take this for what it's worth (the paper it's
printed on ;-).
The 486-100 should be enough to routing purposes, as well as
firewalling/masquerading. If that is *all* you want to do, then you
don't need much more than the mo-board, cpu, ram (8MB is enough, but
16MB is definitely better), ethernet card(s), and a floppy.
Notice I left a few things out:
(1) video card (and a monitor) -- once you have it configured, you
don't need a monitor attached to it, since it'll be fairly
automated; if you want to work on it, you can either telnet in
from the other computer or attach a serial line to either a dumb
terminal or to the computer itself (so, yes, the pentium and the
486 would be connected twice), since the kernel can treat a serial
line like the console;
(2) hard drive -- if you're planning on doing just the
routing/masq-ing, then you don't need a full distribution on it.
LRP, or the Linux Router Project, is designed to put everything
you need for a router (or dialup server or minimalist anything) on
a floppy ... no hard drive to mess up or worry about screwing up.
Boot it up and it works. The floppy is never touched again unless
you update the configuration.
However, if you want to mess around with it, see how it works, and
play with a full distribution, you'll probably want video and a hard
drive for more room and a permanent installation.
As far as a video card goes, you can get away with a cheap SVGA board
with 1mb of onboard memory; however, with prices how they are, you can
easily get a slightly better card for a little more money. The
monitor ... well, you probably know enough about monitors yourself to
go with that. Just make sure that you have access to the timing specs
(listed in the owner's manual).
For the hard drive, I'd recommend going with no less than 400-500MB
for some room to play with. I don't know if you can buy them that
small these days, though ;-) (I've been playing with linux for years
now, and I've lived happily with 1GB for a while now.)
I'm assuming that you'll have two ethernet cards in there: one for the
cable modem side, and one for the local network side. (If you were
planning on using just one in the linux box and using IP aliasing, I
would strongly recommend against it, but that's a different issue
altogether.)
If you plan on doing other things, such as compiling, games (linux has
games? where? :-> ), etc, then you may want to opt for a pentium or
more. Everything will still work with a 486, though.
Before you make any purchases, just double check that it'll be
supported by linux on the Hardware Compatibility page:
http://www.redhat.com/support/docs/rhl/intel/rh52-hardware-intel.html
Okay, this is going to be a bit redhat-centric, but it gives you an
idea of what to look for. What works for redhat will work for other
distributions. (There may be things that aren't listed that do work,
though. *shrug*)

Really, it can be whatever you want, with certain restrictions.
If you're running your own (caching) name server, you can master any
domain you'd like. Keep in mind that it shouldn't shadow a real
domain (therefore making the registered domain unavailable to you and
your hidden subnet). There are advantages with running your own
caching name server; one, apropos to this, is being able to control
this stuff.
This isn't an issue if you hard code all names into /etc/hosts,
though. If you just put:
192.168.2.1 box1.my-own-domain.com box1
192.168.2.2 box2.my-own-domain.com box2
on both machines, it'll work just fine.
You'll probably want to muck around with /etc/resolv.conf and change
the "search" parameter, but if you aren't running a local name server,
then putting a fake domain in resolv.conf will waste bandwidth
whenever you do a non-qualified hostname lookup.
My box, running a caching name server, masters a domain that I call
vabch.va.us. AFAIK, it is not a valid domain (nobody's running it),
so I don't worry about shadowing a real one.
