Subject: Question about multiple tcp/ip host addresses
Date: Sun, 12 Mar 2000 17:21:12 -0800
I'm trying to set up linux to accomodate both an ethernet lan and a
dialup connection to the internet. I managed to get the ethernet card
configured this weekend so it talks to several other Windows pc's on the
lan, and managed to get Samba configured well enough so the linux box
was visible from the p.c.'s Network Neighborhood's. But I'm not sure
where to start configuring tcp/ip for the modem. In the Windows
environment, I set up two tcp/ip "protocols", one bound to the dial up
adapter, the other bound to the ethernet card. They had different tcp/ip
addresses. The lan address was, say, 172.16.2.2 with a subnet mask of
172.16.0.0, but the tcp/ip protocol bound to the dialer obtained its
tcp/ip address from the remote server automatically.
Can anyone give me some suggestions here? Where to look for information?
Nothing I've read so far seems to address the issue of dynamic
addresses. And do I have to do tcp/ip aliasing? I've loaded Redhat 6.1
and there's something I remember reading somewhere (among the thousands
of pages of stuff I've been reading this weekend) about having to
recompile the kernel to do aliasing. I thought I'd ask before diving
into this next part.

Haven't tried the Coral distribution of Linux, but if it
uses the KDE windows manager, I might be able to help. Under
KDE, there is an app called "kppp". It is a lot like the old
Dial-up Network (DUN) program under Win9x, except a bit
easier to use. Alternately, you might want to check out any
reference to ppp or PPP in your Coral manual. In any event,
I don't believe NetZero is aware of Linux, or even Mac's for
that matter. So, you may have a problem just finding which
DNS server to go searching for -- let alone a finding a
domain name. Might email the netzero folks, and ask for all
the revenant ip's and stuff.

Some free isps demand that you use their own software, which pushes
advertisements at you. If that is true of netzero, then youneed another
isp.
however, try it.

It is "easy" Set up your system to connect via ppp to the other.
For step by step instructions about setting up ppp under Linux, see
http://axion.physics.ubc.ca/ppp-linux.html
However, where did you get those 172.16 addresses from? Youcannont
simply grab any old address. a) someone else may own it, and b no router
will know how to get packets to you.
If you have not been officially assined those addresses, use
10.x.x.x or 192.168.x.x as they have officially been assigned as
non-routable addresses which can be used for privat networks.
If 172.16 is official, then all you have to do is to get the machine you
telephone to to know that it must route all such packets to your
machine.
Otherwise you must use IP masquarading ( and no youdo not have to
recompile your kernel. It is already in there. That is one reason modern
distro kernels are so big-- they have everything in them).

Hello to all:
I have finally put the pieces together to put together a mini Printing
how for HP Deskjet users (I have a DJ 722).
The next pieces to add are:
- How to preserve color images when converted to PS in preparation for
printing
- How to configure a simple printcap file to accept both ascii and PS
jobs to their respective spools. Right now I have simple shell scripts
used for printing, one each for ascii and PS->ascii.
Any help on the above two would be appreciated.
I will place the HOW-TOs somewhere in the near future (heck - redundancy
never hurts for those hard-to-do tasks).
You can also feel free to check my web page - www.info-secure.net (soon
to be online once the domain transfer occurs and some DNS issues are

There is no need to redirect to /dev/null, as the -q option to
grep accomplishes the same thing. Note that it is better to also
use the -w option, and to allow for other ppp devices than just
ppp0 (such as ppp1, ppp2, etc.). Either ifconfig can be used, or
route, or better "netstat -nr". The last is probably preferable
because it exists in the path of normal users. Or perhaps using
a full path name is really best for any command called from a
shell script anyway... hence,
if ifconfig | grep -qw ppp[0-3];then
do your thing here ....

pppd executes the script /etc/ppp/ip-down when the connection goes down.
Debian's ppp package installs ip-up and ip-down scripts that run
'run-parts' over the contents of the directories /etc/ppp/ip-up.d and
/etc/ppp/ip-down.d respectively. Packages such as exim and chrony that
need things done when ppp goes up and/or down can then install scripts in
these directories.

The population number itself is misleading -- the town is awfully

Well if one goes on population alone, you could even count NYC as a

Checked scanlogd? It writes to the system logs when a portscan is
detected. You can probably have it E-mail you or beep or something, too.
I don't think people who aren't logged in can detect the program, as it
just watches ports and doesn't send anything out. If scanlogd didn't come
with Slack, it's on freshmeat. HTH,

I'd suggest upgrading all packages to at least the 'october gnome'
versions.
I never had the problems you describe, but have found that october gnome
and newer (except for some of the 'testing' packages, which is to be
expected) are much more stable.
The versions on the RH6.0 cd are quite old seeing as how gnome has been,
and still is, under heavy development.
BTW: xloadimage is part of the xloadimage package.

Everyone said "yes." My follow-up question is how much space should I

My modem can be PnP... or you can set com/irq with jumpers... which was why
I bought it in the first place.
Have you opened your case and checked out the modem? PnP is not
impossible... but if you have jumpers... I would use them.

They just don't want people running an amazon out of their apartment... they
want you to buy their @work service. The fear greater than someone eating up
tons of upstream bandwidth is rookies running insecure servers, getting
hacked, and making @home look really bad to other networks and the media.
I think the suits are the ones saying no servers, but the sys admins that are
doing the watching know better and are going to be more lenient on a
low-traffic service like mail. They may not even peg you if you've got ftp
open if they see there is hardly any traffic. What you could do is run the
deception toolkit and when they ask, tell them, if they ask, they aren't real
servers... they're just perl scripts pretending and catching hackers.
If you're going to run a mail server, please don't use sendmail. Use either
qmail or postfix as the latter are secure.

Which has exactly the same problem...
Note that none of the discussion below addresses the problem.
>From a virtual console on a Linux box one does NOT get a vt220
emulation with either telnet or rlogin. What you get is a
"linux" terminal.
The difficulty is that the distant host might be so old and
crufty that it does not have a proper terminal description in
its TERMCAP or TERMINFO database. Hence a user can attempt to
use one that does exist and which is similar, such as vt100, but
the results are not a perfect match and certain things, which
differ from one terminal to another and may differ with older
database entries, will not match. (There are roughly 101.3
different xterms, and 524 different terminal descriptions for
those xterms. Hence it is very arbitrary in which way they
do not match. :-)
The only perfect solution is to have a perfect terminal
description _for_the_terminal_in_use. (vt220 and ansi terminals
are not likely to be close to most xterms or to any UNIX
variety's console.) But typically a proper fix can easily be
obtained by either 1) getting the systems admin people on the
distant host to add a "linux" description, which any Linux box
can provide easily (rtfm on infocmp), or 2) setting up the
user's login profile on the distant host to use a private
terminal description database, which has a "linux" (or the
approprite xterm) description in it. RTFM on terminfo.
Using other terminal names to set TERM, whether it is
accomplished using "TERM=xxzzy telnet host", or manually setting
TERM at the distant end via tset or any other way, will *NOT*
provide a better match between a linux console (or an xterm)
and any of the various incorrect terminal descriptions that have
been suggested.

A full RHL6.1 server class install will take up about 350 meg. Add as much
extra space for what you want to do with it, and another 100 or so for a swap
partition and you'll be set. Memory will be more of a concern than disk space
will. Don't expect to get anything done in a GUI enviornment with only 32 meg
of ram. KDE will only start to run okay with 64meg. Don't know about gnome
or X though. I have a mere 32 meg in my server and it runs really well....
but that's because it isn't running a window manager... command prompt only.

I had the advantage of starting from RH 6.1, and Gnome is the default. I've
also upgraded, but I started with the GTK libraries first, and then downloaded
October Gnome specifically for RedHat from www.gnome.org. Finally, I upgraded
to the latest RPM release of Enlightment, but I greatly preferred IceWM as the
WM. It's time consuming, and it is only slightly better than the distro
release. It IS a pig, and it runs slow on my machine (P133 w/ 64MB RAM), TOO
slow. I love how it looks, but the new themes for IceWM are pretty decent, so
I usually run that alone. BTW, Helix is beta-ware, and they clearly advertise
it's not for anything older than RH 6.1. Finally, there are a large number of
complaints from people who try to run it as root-- something running in the
background makes the hardrive thrash. I don't know all the details, but it
seems RH does funny things on some hardware, but not all.
In the future, you might be careful sticking to RPMs packaged just for your
distro. Too many uncompiled apps just aren't written for RedHat, it seems.

Check out Tom Swan's book, ISBN: 0789721538 entitled
Tom Swan's GNU C++ for Linux
The book is very practical and helpful especially if you're planning to
learn C++ under Linux. Please note that I tend to slightly disagree
with some of Tom's discussion on more pure OOP points he makes,
however, for a C++ Linux book, you'll not find any better comparison.
It is a good book...though I haven't gone completely through all of it
since I only received it a couple of weeks ago. I have compiled all
of the source code that comes with it --and all of it compiled
successfully on my Linux machines. Remember to unzip the source
code using the -L option under Linux to make the filenames lowercase
rather than DOS CASE, WHICH IS CRAP ESPECIALLY UNDER
UNIX.... :)
The X Window (xlib) and V sections are well worth the price of the
book if you're planning on entering into GUI programming. It also
includes a release of Linux if you don't currently have one.
Lastly, don't believe too much about what you hear regarding the
lack of quality with g++. I find that it is one of the best compilers
around especially for cross platform compilations and it has
relatively robust "standards" support. I'm sure that some esoteric
feature of C++ (a very complex language specification...anyone
wanna tell me why we have auto_ptr in the standard?) isn't
"properly" (someone's interpretation at some levels of the standard)
supported. I feel that g++ allows me to do real programming work.
Since my total Linux "indentured servitude" is on the order of $100
per year, I'm not complaining since I'm also targeting SH and MIPS
along with "traditional" x86.
