I really can't imagine how to setup C news accidentally. You have to manipulate
|
|
the crontab, for example. To know this, you most probably will read the
|
|
README file (in /usr[/local]/lib/news, in most Linux distributions).
|
|
In this file, there's also the mailname, organization,... setup described.
|
|
|
|
I think that's a standard problem: people don't read [all of] the
|
|
documentation.

Subject: Optimizing CSLIP performance via kernel TCP parameters

Hello
|
|
|
|
Recently I succeeded in getting cslip to work between Linux and a
|
|
SUN IPX by installing cslip-2.7 on the SUN end. To improve performance
|
|
the CSLIP documentation recommends reducing the default TCP buffer
|
|
sizes on the dialup client side (i.e. my Linux box). Does anyone know
|
|
how to do this since I couldn't find any reference to the parameters
|
|
tcp_sendspace and tcp_recvspace (mentioned in the CSLIP guide) in
|
|
my Linux kernel code.
|
|
|
|
Finally, it was recommended in the CSLIP docs to make the retransmit
|
|
timer more conservative and an example was given on how to do this using
|
|
the 4.3-tahoe networking code. Could anyone tell me how to do this
|
|
in Linux? Any other suggestions for optimizing my CSLIP link would be
|
|
greatly appreciated.
|
|
|
|
many thanks
|
|

to fix the (libc 4.5.25) bug which caused this. While you're at

You have to use /dev/nftape for this:

nftape = non-rewinding ftape.

Incidentally, if ftape is working for you, please tell us:

What kind of crap is that??? Sure I realize that a lot of people do

go around and break into systems, but I have found that a whole hell of
|
|
a lot of the security problems are discovered by system admistrators
|
|
that are the types of people who have open minds and have a habit of
|
|
trying to do every possible combination of a configuration for a
|
|
program or server just to make sure it's as bug free as possible. A
|
|
good sysadmin who really wants his users to have a very efficient
|
|
system will make sure everything runs right, and this means that
|
|
they are very likely to find bugs eventually. Those people that call
|
|
themselves system adminstrators, but actually just copy other
|
|
peoples configurations with no knowledge of how they work, typically
|
|
don't have enough knowledge of what they are running to realize that
|
|
there is a security problem and how to either fix it or duplicate so
|
|
they can repair the problem.
|
|
|
|
There are some things that I am very good at and can find problems with,
|
|
then there are some things that I have no idea how it works (Smail is
|
|
one of those that I'm not familiar enough with realize if something
|
|
is wrong), but whenever I hear about a security problem I want to
|
|
know how I can check if it exists or not. Just saying "Smail has a
|
|
security problem" doesn't help me any. Either do one of 2 things,
|
|
tell everyone what the problem is in detail so system administrators
|
|
can try it and see if their systems are at risk and they can try to
|
|
fix it, or give out the patch or the fix with the original message
|
|
of the problem.
|
|
|
|
I'm one of those people that find illegal hackers and turn them in
|
|
and believe that laws aren't strict enough against it, and I also
|
|
find security problems in programs too while maintaining local
|
|
systems. I actually take your comment as an insult to system
|
|
adminstrators that try to make things better since they are the
|

ones who report the bugs that you see on here. I doubt an illegal

hacker is going to give out their 'secrets' in this list anyways.

Subject: strange lockups, bizarre networking...
|
|
Date: Mon, 10 Oct 1994 00:40:14
|
|
|
|
As was posted several days ago, my machine is one of those which has been
|
|
having strange lockups the past weeks. Basically, when I upgraded from 1.1.10
|
|
to 1.1.45 (and now 1.1.50), my system will occasionally hang hard. A
|
|
power-reset is the only thing to bring it back.
|
|
|
|
Another person sent me a possible fix, claiming that it may be a portion of
|
|
the ne.c code (the system does use an NE2000 clone). However, that patch did
|
|
not stop the lockups from occuring. I suppose I may need to invest in another
|
|
network card...
|
|
|
|
Before doing that, though, I thought it might be beneficial to the Linux
|
|
developers if I told them some more about the symptoms we've been having
|
|
lately.
|
|
|
|
Usually, there are 4-5 machines active on the network. 3-4 WfWg machines, and
|
|
1-2 Macs. The Linux machine is a Dell 486, 720 MB IDE drive (w/ 30MB SWAP), 8
|
|
MB RAM, and an NE2000 card. The Linux machine is also connected to a 28.8 K
|
|
modem, and runs DIP to connect our LAN to the internet. It is connected to an
|
|
additional modem and runs FlexFax. Finally, the machine also runs SAMBA to
|
|
serve files/printers to the WfWg machines. I am currently working on making
|
|
CAP work, and at times it is running some CAP processes -- but usually not for
|
|
very long. And in any event, running CAP is not consistent with the times the
|
|
machine hangs.
|
|
|
|
Finally, one more bit of information. Often times the hangs are preceded by
|
|
periods of sluggish network performance. My telnet logins to the machine will
|
|
simply sit there as I type commands, then eventually they'll work.
|
|
|
|
Also, tonight something VERY strange happened. My Linux machine stopped
|
|
responding to my LAN, so I ran "arp -a". Only two machines were listed, but
|
|
both had a hardware address of 00:00:00:00:00:00.
|
|
|
|
It looked like this:
|
|
|
|
Address HW type HW address Flags
|
|
(ip of machine 1) 10Mbps Ethernet 00:00:00:00:00:00 C
|
|
(ip of linux box) 10Mbps Ethernet 00:00:00:00:00:00
|
|
|
|
Running it now, arp still reports 00:00:00:00:00:00 for the linux machine
|
|
(itself that is) -- I don't know if that is correct or not. It does, however,
|
|
have the correct address for the other machine now, and it has it's own
|
|
correct address when I run "ifconfig".
|
|
|
|
Anyway, these are the facts. If any of the developers can figure out how to
|
|
get around these hangs, I (and several others I know) would be greatly
|
|
appreciative. I hope that this information will help, and if I can be of any
|
|
more assistance, please let me know.
|
|
|
|
Thanks!

Oh, criminals. Give me a break. The criminals are the ones that mess with
|
|
things. I consider myself a (wannabe, at least) hacker in the original
|
|
sense, and in HS was a "hacker" in the new sense. I never altered
|
|
ANYTHING. I got in, to get in, or to use a compiler. Nothing criminal about
|
|
that (except in the eyes of the law.) Penetrating the security of a
|
|
computer system is totally harmless in and of itself. It's the defacing
|
|
of what one finds, or the spreading of info that are the problems, and
|
|
have made folks so paranoid they 'throw the book' at anybody who pokes around
|
|
a little. Hey, I'm gonna see where I can go. I also understand, as the owner
|
|
of a system about to be on the net, the paranoia, and will surely bounce
|
|
anyone who gets on my system off as quickly as I can, not knowing that they
|
|
are as nice as I am. (I even had operators do poor jobs of throwing me off,
|
|
which pissed me off, because understimating your 'enemy' is stupid, and the
|
|
worst I ever did (once) was get back on, do a stop proc /id=blahblah (VMS) and
|
|
abdicate. Just to let him know he screwed up and his back was wide open and
|
|
somebody nasty could have caused him some trouble. ) But I will never attempt
|
|
to get someone in legal trouble who has not destroyed something. This
|
|
'throw the book at them' mentality for poking around is pathetic and
|
|
(overused cliche word.) fascist. True, a lot of these system crackers
|
|
are malicious little bastards, the same sort who write viruses (or would if
|
|
they could), but judging intent before an action is a pathetic reaction in
|
|
the direction of security over liberty. I fully understand the worries
|
|
involved here. But the criminalization of the curious is pathetic and
|
|
computer-bureaucrat-like. Let's reserve the word 'criminal' for those
|
|
who break things. What I generally did after I got in was tell the op.
|
|
what I did and how I did it and ask for a user account (in exchange for
|
|
the niftier root or SETPRV, READALL, etc account I had.) A fairly
|
|
helpful little vermin, I was. I despised anyone who deleted or defaced
|
|
anything, as did most of the (good) "entry experts" of the time. This was
|
|
say ten years ago.
|
|
|
|
>original meaning of the word. To refer to such people as `hackers' is to

|
|
|
|
Depends on how ingenious their attempts to enter a system are. This is a
|
|
dogmatic view. "Hacker" and "non-malicious-system-tourist" are not non-
|
|
intersecting sets. Back in HS i performed entries that qualified as hacks.
|
|
|
|
Today? There is enough to do without entering other people's systems. I've
|
|
got a Linux box that beats the crap out of 99% of the systems I used to
|
|
want to get into. (why get in? I often wanted a c compiler. not gonna
|
|
get that on an apple II+.) Also, there are 50 bizillion fascist hardass
|
|
computer bureaucrats waiting to hurl that book. Also, there is the risk of
|
|
being identified with the aforementioned malicious little
|
|
you-know-whats. Barring that, I might still poke around. Curiosity is not
|
|
a crime.

/usr/bin/passwd is not setuid in the slackware 2.0.1 installation.
|
|
|
|
to fix:
|
|
|
|
1) login as root.
|

2) cd into /usr/bin

3) chmod u+s passwd
|
|

It will now work.
|
|
|
|
Why it didn't work: To be able to write /etc/ptmp and then update
|
|
/etc/passwd, your must be root. So passwd is executed setuid, which
|
|
means it is run as if it had been started by root. (To see this for
|

yourself, start passwd and then run ps aux--it will show up owned by

root.) This allows all the necessary files to be created/changed/updated.

Subject: HELP: CDROM & Modem Installation?
|
|
Reply-To: BruceBigby@Aol.com
|
|
Date: Thu, 13 Oct 1994 17:06:36 GMT
|
|
|
|
Recently, I purchased Yggdrasil (RevB?) and am awaiting its arrival in the mail.
|
|
I have a multifunction board, called the ACE 5000, from Best Data Products
|
|
in CA. The board is fantastic! It features a DSP (Digital Signal Processor)
|
|
MWave Technology for excellent voice/sound reproduction, MIDI features (16
|
|
instruments), a 14.4k Data modem/FAX (software upgradeable to 28.8k),
|
|
and is Soundblaster 16-bit compatible. It also has a Panasonic-compatible
|
|
interface for CDROM and support that enables you to connect the audio of
|
|
another CDROM to it so that ACE applications can process its audio, but I don't
|
|
use the feature since I purchased an inexpensive Sony CU33A CDROM and
|
|
interface board. Here are my questions:
|
|
|
|
1. Under Windows, I access the modem features of the board by running
|
|
one of several modem applications: 2400B through 14.4kB. Once the
|
|
modem "driver" is running, communications applications access it
|
|
through COM3. The COM port is configurable. The modem application
|
|
is Hayes compatible, of course. Is there a driver for the ACE
|
|
that exists! It is a fairly new board.
|
|
|
|
2. I recently purchased a Sony 2X CDROM, because it was very cheap.
|
|
Under DOS, it is not in interrupt mode because I don't have any
|
|
spare IRQs, unless I do some major reconfiguring. Do I need to
|
|
have my CDROM drive in interrupt mode for Linux to recognize it? If
|
|
so, here is my next question:
|
|
|
|
3. My CDROM can use IRQs 2, 3, 4, 5, or 9. I have a bus mouse that
|
|
accompanies my ATI Ultra Graphics Plus video adapter/accelator; it
|
|
is Mach 32-based. I do not use the mouse because I already have a 3-button
|
|
Logitech serial mouse that is on COM1, IRQ4. I can free up this
|
|
serial port if I use the bus mouse. Does Yggdrasil Linux have a
|
|
bus mouse driver built in? Will it detect it upon installation? I
|
|
am not sure whether it is PS/2 compatible. I suppose it is. Can
|
|
I simply use IRQ9? MSD says that this is a redirected IRQ2. What
|
|
does this mean and is IRQ9 available or is it off limits? I suppose,
|
|
under LINUX, I could use IRQ9, but this might screw up DOS...any
|
|
takers?
|
|
|
|
4. I do have a second modem, a Telebit Trailblazer, that currently
|
|
is taking up COM2/IRQ3. I suppose if I use this modem, instead of the
|
|
ACE 5000 modem feature, I won't need to worry about obtaining a
|
|
driver for the ACE. I would like to get rid of this modem, but may
|
|
keep it anyway. If I can get rid of it, I can setup my CDROM to use IRQ3.
|
|
If not, I must keep it since I might not be able to access the modem
|
|
features of my ACE.
|
|

Not if you're using the -i option, ignore bad block. Tar tries to resync
|
|
in case of checksum errors.

Hope this helps

Yeah, have a look at /etc/resolv.conf. There might be a reference to an
|
|
unknown name server. Looking up this name server gives a timeout, that's
|
|
(perhaps) your delay. Also have a look at /etc/host.conf whether bind
|
|
or nis is referenced. If there's no name server (and no nis for that
|
|
matter) you might as well delete these key words, leaving only hosts
|
|
(for looking in /etc/hosts).
