hi there: I'm new to debian and have a working debian 2.2 system. Now I
would like to upgrade a few (but not all) programs to their unstable or
proposed upgrades versions (specifically navigator to 4.75 and wm2).
What's the easiest way to do that. Guess I could download the new version
and then use dpkg. But can I include some woody lines in apt/sources.list?
thanks, Gerald
PS: and while we at it, how do I find out what files a given package
contains and what package a given file on my system belongs to (if
any)??

You can use ipchains and ipmasqadm which will meet most of your
requirements. I am not sure that ipchains can handle all games. The
relevant HOWTOs are
http://www.linux.no/biblioteket/HOWTO/IP-Masquerade-HOWTO.html and
http://www.linux.no/biblioteket/HOWTO/IPCHAINS-HOWTO.html
You should however not use the same machine for http, ftp and mail
servers and firewall. The firewall should be a separate box (a 486 will
do). This is because the more software that runs on the firewall, the
more security-holes you introduce. You should rather forward incoming
requests for those services to a server inside the firewall.
Intrusion detection is not mentioned in the HOWTOs above and I know
nothing about it.

[Crossposted to c.o.l.m and r.c.m for reasons that will be apparent;
PLEASE check the Newsgroups line if replies veer too far off topic!]
In article <8pfb21$[EMAIL PROTECTED]>, [EMAIL PROTECTED] says...

And then, according to the site, a DPS (=Dept. of Public Safety) officer
will then come and inspect your home to make sure that you are not planning
to threaten public safety with your glassware. It's all done very nicely
and politely, apparently. Having looked into this a little since Uncle Al's
initial post, I can report that the law seems to be the same in a number of
states (including NY). I think that in my case I'm not in violation merely
by owning the glassware (God help me if they find out about my vacuum dryer
though!) as a permit is required only to "purchase, sell, or transfer" such
items. Of course next time I purchase a piece of contraband I'm going to be
liable for a big fine, I guess. Because there is no way in hell that I am
going to fill out a "simple form" to apply for a... glassware permit.
Anyone else here -- regardless of whether you have glassware at home or
not -- really incensed by all this? ...I'm no NRA member. I don't own a
gun, I don't particularly want one, and I frankly find a lot of the gun lobby to
be extremely creepy. I understand, even feel some of the fear that led
to increasingly restrictive gun registration requirements. But those creepy
folks have a very important message for us: our *inherent* right to do whatever
we damn well please and thereby express and realize ourselves as individual
entities (to borrow dippy hippie jargon for a change) so long as we are not
infringing thereby on the rights of others, is being steadily eroded by
manipulation of the public hysteria over very real social problems (violence,
drug addiction, etc...), and each new restriction, each new registration
requirement, each new creation of a victimless "crime", each new law mandating
that public agencies report to the government on private citizens' activities --
all contribute to that erosion.
It's not too hard to get a glassware registration requirement enacted into law.
After all, most people don't own lab glassware and don't particularly want to
(just as I don't own a gun and don't particularly want to). There is manifest
evidence that some -- God knows, perhaps a majority -- of the lab glassware
in private hands is being used to manufacture drugs, and nearly everyone
agrees that our society has a problem with drugs, so on the surface of it,
putting a burdensome restriction on owning glass in funny shapes (GLASS,
for God's sake!) seems reasonable to lots of people. And if you up and
complain about it, you're going to be pegged as an eccentric or a whiner,
because it's not that big a deal, is it? If you're a homebrewer or whatever,
just fill out the forms, submit your personal data, and so on and everything
will be fine! (At least until they revoke those permits and come to your
address of record to confiscate your glassware -- or arrest you because
a drug lab was busted nearby and you, as a known glassware user, came under
immediate suspicion.)
The thing is, the principle of "give 'em a centimeter and they'll take a
kilometer" applies here. Except it's not so much "them" as it is "us": we
live in a participatory political system, and we do this to ourselves, by
allowing the voice of the majority to override common sense. One day it's
glassware, and you don't use glassware, so you say nothing. Next, it's guns,
and you don't like guns, so you say nothing. Then it's machine tools, which,
just as glassware can be used to make drugs, are quite useful for making guns.
You're not a home shop machinist so you don't care. Sooner or later, it's,
let us say, computers (after all, the illegal uses of computers are many and
varied. There does need to be a registration and licensing system, doesn't
there? Just so that people can be held accountable for what is done with their
PCs, as they are with their cars?)
And you *do* use computers, so you're well and truly pissed off about the
new requirements, but... it's too late. So you submit, fill out all the
forms, pay your license fees, grumble a little, and get used to the new rules.
And a few years later you're arrested for illegally running Linux 5.0.4, a
non-approved underground operating system, and filtering your net connection to
hide that fact. You weren't doing anything wrong, you think, just trying to
get a little more efficiency out of the inexpensive PC that was all you could
afford on your office job pay (too bad that programmer's job was out of reach,
you just couldn't meet the licensing requirements), but everyone knows that
the vast majority of Linux users are criminals, trying to defeat the layers
of protective software that wrap all modern computers and get down to the
bare-bones hardware, whence they can violate copyright protection, make
anonymous connections to internet sites, launch cracking attacks on the net,
and bypass transaction logs when trading contraband information. Many of them
even use highly illegal cryptography!
Computer-related crime is rampant, with young kids being drawn by the sheer
excitement of it into illegal computer gangs. The gangs, unfortunately, are
involved in lots of real violence. They pass around encrypted information
on using contraband and homebrew machine tools to build crude guns, and
highly illegal glassware to make drugs and explosives, and the streets are
less safe than they ever were. There's a lot of public griping about it,
and even a few people pointing out that things were better -- not perfect,
but better -- in the old days, but public policy continues to state that
all the violence is evidence that yet tighter restrictions are necessary
on computers, to wipe out the computer gangs once and for all and make the
streets safe again for good citizens.
Sometimes you reminisce about the days when you experimented with your
computer, when you were allowed to write code without a license for your own
enjoyment and edification. Once you got drunk with a couple of your neighbors
and, emboldened by the buzz you got from drinking six cans of horse-piss,
you let on as to how you used to be a pretty good coder yourself. But then
Tom started going on about how he used to be able to brew his own beer,
which was far better than this crap, but then they took his glassware away.
And Mike kept mumbling about how he used to build stuff, actually build
stuff, with his lathe and his mill. And John got very quiet and turned livid
with suppressed rage as he recalls the day that he had to turn in his
electronic test equipment and the radio scanners that had been his big hobby.
Even Millie, Tom's wife, injected a complaint about the monthly mandatory
garden inspections, to make sure that no marijuana, psilocybin mushrooms,
Hawaiian woodrose, Mexican sage or other botanical contraband was growing in
her vegetable patch. And you started to get nervous, or maybe just bored,
said goodbye, and tottered back home and off to bed...

It is not real clear what you mean here. Are you saying that
Ctrl-Alt-Backspace does not get you out of X and back to a prompt? And
that even if you do a hard power cycle you cannot get back to a prompt?
I will agree that XFree86 can be rather painful to setup.

You might try something such as Electric Fence (-lefence) to locate
any dynamic allocation errors.
If you have access to it (it's not free!) you can also try
Purify, from Rational Software -- although I don't know if there's
a Linux version or not.
