Although I understand your frustrations, I think people SHOULD post detailed
|
|
information about wholes that exist. I don't know if you remember, but the
|
|
"worm" incident on the internet on the 80's got worse than it should have been
|
|
because key usenet/email nodes decided the best way to defeat it was to
|
|
disconnect themselves from the net. But they didn't realize that this also
|
|
prevented them from receiving very important informations about the worm. The
|
|
pointer here is that, yes there will always be these loosers who with malice
|
|
try to break into other people's machines, but the best way, as far as I know,
|
|
is to educate people about why and what is wrong with the security system, not
|
|
just provide ambiguous patches. Things like COPS or any network tracers can be
|
|
very dangerous in the hands of the wrong people, but that doesn't mean that
|
|
we should eliminate them.

Recently, I've noticed an increase in postings where the
|
|
authors e-mail address is showing up as:
|
|
|
|
(some name) @myhost.subdomain.domain
|
|
|
|
or other non-legal Internet addresses. Could you please fix
|
|
this problem as soon as possible? If you are able to post
|

messages, you must have some type of valid address, whether it

oversight by some new sysadmin, and not an attempt at deceit.

There was a bit of a controversy a few months ago, when America

On-Line added Internet access to its service. The Internet

competition between Internet service providers lowering prices,

their boxes on the Internet. We must remember to act responsibly
|
|
with our machines, because now, instead of practicing poor

problems.

I like what I have seen of Linux so far and would like to try it on the side.

Can I install it in some empty space set aside at the end of my drive? Can I use Bootman (os/ two) sorry, no number keys running) and boot into linux. I would just use my dos fat and os-too partitions mounted in the normal way. If it is set as a bootable partition, but not the primary one will it work or just be

Sounds like you need more RAM. I have run Linux on a bunch of
|
|
different machines from a a 20 Mhz. 386 to a 90 Mhz. Pentium. They
|
|
all seem to run much faster with at least 16M of RAM.

I just installed the latest release of Slackware (2.0.1 I think) and am

having problems with LateX/TeX. In particular dvips. First time through
|
|
I only installed what I needed. I re-installed again this time installing

everything (to play it safe).
|

Basicall, it looks like dvips is not finding any fonts and when it

run Make...PK it fails on every font.
|
|
|

I thought I would ask first before I go throught the hassle of starting

from scratch and installing myself. All the fonts seem to be in place

and latex has no problems assemling my document.

And you have to do it after every time the printer gets a software reset.
|
|
A bit tricky if you want to have the same printer configuration work for
|
|
DOS and Linux at the same time. I have a set of configuration switches on
|
|
my DJ550C that can select the CR/LF interpretation at reset time. I leave
|
|
it in DOS mode, then I send a reset string during system startup, and I
|
|
modified the output filter that LPR uses to send the same string after it
|
|
decides to do a reset (like after sending a postscript file, before it returns
|
|
to text mode). Does the LJ printer also have these configuration switches?
|
|
If you only run under Linux, you can configure the printer for Linux and
|
|
not worry about it anymore. If you want Linux and DOS to share, then
|
|
you need a more complicated solution.

Just buy one 'o those small 1-2 cubic foot refrigerators and modify it
|
|
into a PC enclosure. That way, your WHOLE machine runs cooler, and you
|
|
have someplace for beer besides.......
|
|
|
|
|
|
This is only half a joke, BTW - I actually considered doing this to try
|
|
to get my (Intel) DX2-66 to run at 100 MHz. It runs fine at 80; when I
|
|
try to speed it up more the external cache fails. Chips run faster at
|
|
the cooler end of their environmental range, by a factor of 20% or more.
|
|
|
|
Another way to speed things up is to crank the voltage up a bit. 5V chips
|
|
often work fine up past 7V; works fine in the lab, though I'm hesitant to
|
|
do it to my machine at home. Heat becomes an even worse problem as well.
|
|
|
|
(I know the above from job-related testing of standard commercial devices
|
|
in liquid nitrogen. At -200 C we would routinely get a 2X improvement in
|
|
device speed.)
|
|
|
|
|
|
PS: Ran some benchmarks on my nominally 80 MHz machine; I saw only a 6%
|
|
speedup in CPU-intensive tasks. This implies that I'm RAM limited, not
|
|
CPU limited. BUT my video performance went up 16%; I suspect because my
|
|
VLB is running at the new bus rate.

|
HI,
|
|
|
|
OK... here is the question!
|
|
|
|
I don't seem to have a "network node hostname"
|
|
ie. if I enter the "uname -a " command I get
|
|
|
|
Linux (none) 1.0 #2 Sat Apr 2 03:15:37 CST 1994 i386
|
|
|
|
BTW , WHAT Version of Linux am I on? I don't seem to be able to
|
|
tell iff I am using the Slackware 2.0 or not.
|
|
|
|
So right now my "network node hostname is (none).
|
|
|
|
This is different from /etc/HOSTNAME which I have set to 'home.calleson.com'
|
|
and it is also in my /etc/hosts file.
|
|
|
|
Someone mentioned that there were two different versions of hostname/domainname
|
|
that are installed with Slackware 1.0 and Slackware 2.0...
|
|
Can someone who knows what is going on please expound on this?
|
|
|
|
Thanks
|
|
|
|
The reason I need to have a network node hostname is so I can
|
|
run slip ! right now everytime I enter the DIP command I get
|
|
the response '(none): host name lookup failure
|
|
|
|
|
|
THANKS FOR ANY AND ALL HELP!

Sure, you need to create the file /usr/local/lib/news/nntp_access.
|
|
You might need to make the /usr/local/lib/news directory first, too.
|
|
To allow access from your local host, you might have a nntp_access
|
|
file like this:
|
|
|
|
localhost read post
|
|
|
|
I think if you try a man nntpd, you'll probably get information on

this file format...
