You're in the right place. But, a few good advices on asking questions
here:
1) Try yourself a little bit first. Check if you can find a HOWTO on it
(you DID install all the documentation, didn't you? If you didn't DO so.
Documentation is good). Nothing is more annoying than reading the same
simple questions over and over. If you don't get an answer to a question
that *should* be pretty simple, this could actually be the reason.
2) When you get an answer like "read HOWTO xxx, it's answered thoroughly
there" - then follow the advice. If there's something there you don't
understand, then explain what you didn't understand If you just keep
asking the same question, you're likely to get the same answer, and
someone will get pissed.
3) Remember that the people that answer your questions here are not paid
to do so. Never DEMAND an answer. Always be polite, and never get angry
about answers that tells you to RTFM (Read The Fine Manual). Generally,
you DO learn more from reading the manual. If you're not prepared to do
that, then you're not prepared for Linux. Alternatively, PAY someone to
answer your stupid questions. Yes, you can pay for support for Linux.
4) When you've mastered something yourself, be prepared to help someone
else with it. Usenet needs people answering questions of all levels. If
noone bothers to answer questions, there will be no place to ask the
stupid questions you once asked yourself.

Interesting. The heavily mutated Red Hat box I've got does
have a setuid() man page, but it's for a C function declared
in unistd.h.
You're probably looking for a shell command to set the suid
bit. In that case, check the man page for 'chmod' -- e.g.
chmod u+s /usr/bin/blah
(and also make sure that the executable bits are set such
that whatever account you want to run it, can execute it).

Hmmm. If you don't have a chmod() man page... check to see
whether you installed 'em.

Subject: Maximimun Process Size 555Mb ?
Date: Sat, 07 Oct 2000 17:15:17 GMT
G'Day All,
Righto, we run an ISP and have a Large Linux / Squid proxy box. We put
some more disk in, and our squid process begain to grow (this is
expected) - to this end, we bumped the ram on the machine up to 1Gb.
When our squid process bombs ouy (at 555Mb) we see
"xmalloc: unable to allocate 32768 bytes!".
After much trolling around lists / squid archives etc I just couldn't
find any (linux specific answers).
I needed to work out if it was a squid issue or a memory issues. I
wrote a small C program that mallocs 1 byte at a time. Malloc _always_
fails at: 576797824 bytes. (which is around the same size as the squid
process).
I have also tried intentially getting other processes to blow out
memory wise, and sure enough they all die around the same size. This
has been done on 4 machine (the ones with enough real memory test with
swap off too).
I have gone through all of the ulimit issues etc (all show data seg
size set to unlimited).
So - is there some kind of kernel limitation on the maximum size of the
kernel ? (if so where on earth is it!!!).
FYI: (main squid proxy)
Gigabyte Motherboard
P3 800 (100)
1Gb Ram
Slackware 7.0 (with kernal upgrade to 2.2.16)
With my little "memory test" program, I managed to stop it 1 byte
before the failed malloc - at this point, /proc/process_num/-

Indeed. It's not about smokestack industries; that is so 20th century. Desktop
dominance in the midst of a *worldwide* networking revolution is a dinosaur in
complete denial about the impending asteroid impact. The first time I read the
URL, I literally laughed out loud how desperate MS seemed to get an overpriced
botch like NT likened to Open Source, instead of highend servers like Sun that
were eating NT as lunch. Unless, of course, you're desperately trying to throw
a curveball about the real threat: your illegal desktop monopoly. Faced with a
growing spread of things like KDE, Gnome, and Star Office from "rogue" servers
popping up like gnats everywhere, MS was/is desperate to plug the holes in its
desktop dikes. The *cashcow* is desktop, and MS shareholders *know* it. That's
like holding a stake in the last of great 20th century protection rackets.
They have everything to lose and Open Source doesn't care. Must drive FUDsters
writing this marketing dreck just plain nuts. At least Scott McNealy and Larry
Ellison take MS seriously enough to keep legions of highdollar lawyers busy. I
don't know of anyone except Stallman and Raymond who might stay up nights over
it, on the Gnu/Open side of the fence. Maybe some at Redhat and VALinux, but I
personally don't don't feel Open Source (or I) have a dog in that fight.
Even earlier, I chuckled when MS tried quietly to end NT on Alpha. Those tardy
wretches were having fits backfilling all that Intel/DOS wreckage, on hardware
a twobit "freebie" like Linux had ported and supported for years. Hah! It does
wonders in keeping all the overpaid lapdogs and marketdroids on their toes, in
promoting this "drop-in" diversion, from anything as inflexible as NT.
We had a thread on this almost a year ago when this FUD-full URL popped up. As
I remarked myself (<ZXxM3.61$[EMAIL PROTECTED]>):
|>> Fact: NT has never made a name for itself in competing with comparable sets

|>> virtually owned by Sun and others, while Linux/*BSD are steadily gaining on

Again: nearly a year old news, for my part (11-OCT-1999, IIRC).
I think a year later it's only worse for MS. In fact NT was so embarrassing as
expensive, buggy bloatware, the 5.0 version was repackaged (Win2K) in the hope
the Microsmurfs would be suckered by these MS marketing gimmicks, as usual. It
doesn't help to be found an illegal monopoly after their laughable defense for
blatant antitrust violation by a very reputable, no-nonsense federal judge, in
the year since.

Linux and plug and play is still a shakey marriage. Best, if you can, is
to remove the modem card and set the jumpers on the card for a specific
port/irq. You could say use COM2 but then make sure that when you boot
up you go into your bios and remove the COM2 serial port (Linux does not
share IRQs). Then use /dev/ttyS1 whereiever it calls for your modem
port.

Subject: midi via serial port interface (Portman PC/S)
Date: Sat, 07 Oct 2000 17:40:40 GMT
Has anyone had any luck sending midi data out the serial port to a
sound module? I'm running SuSE 6.4 with a Portman PC/S serial-midi
interface box. So far I have snd-card-serial (as well as
snd-card-emu10k1 for my SBLive) loaded with the following options line
in my /etc/modules.conf:
options snd-card-serial snd_io=0x3f8 snd_irq=4
I have the Portman PC/S connected to /dev/ttyS0 and I've got it to send
_something_ to my sound module (a Roland JV-1010) because the LED's are
flashing on the module, but no sound is produced and when I stop sending
the data I get a Roland error code which, according to the manual, means
bad midi input.
I've also tried the option snd_div=3 up thru snd_div=12, and I've tried
(with even less success) the uart16550_midi module.
If anyone has any ideas about sending midi data through a serial port
(with or without a Portman), please let me know.
Thanks for any suggestions! __sonic

Ident may be pointless, stupid and a security hole. But there is one
fairly good reason to have it on your system. It is required by most
IRC (Internet Relay Chat) servers to connect. So if you use this or
think you might at some point, you might want to think twice about
disabling it.

Actually you also have to read the man page when you open it.
setuid is a subroutine, not a user callable program.
To set ANY file attributes with a program the relevant thing is
chmod

I would agree but as long as system's maker's or reseller's do not offer
any other choice when a buyer orders a new computer then M$ will always
have an advantage over any other system available. Though many now offer
linux on servers they do not offer it for desktop systems. From personal
experience, when I went to buy my newest system I couldn't even buy one
without an OS (let alone with linux preinstalled) which wasn't any big
deal, I just built my own system and eliminated the system maker,
reseller, and M$ from selling me something I didn't want or need.

Hi,
I've got a strange proglem since I installed RedHat 7.0, with 6.2
quake and quake2 run fine, but now I cannot start those any more.
And what is weird, the shells complains that "no such file" but
the executable is there, some programs (like file) do recocnise
it and some others (like ldd) don't.
This hasn't anything to do with libc versions, has this? The
shell doesn't matter. The box is simple RH7-Gnome-wksta.
Any help appreciated. A script example below, same happens
with quake2 (version 3.20 not-glibc) as well.

Date: Sat, 07 Oct 2000 12:50:36 -0600
Hello,
I think I may have finally found an MTA made for the home user.
masqmail
I am having a bit of trouble getting it configured correctly, and would
appreciate some assistance if at all possible.
My scenario:
Main computer for day-to-day use is ishamael.inet, at 10.0.0.4, w/ my
normal username being 'monte'.
ishamael is behind a firewall 'shaitan.inet' running freesco 0.26, which
has an internal address of 10.0.0.1 on eth0 and uses a modem to dial out
to the isp.
I access my email thru a Yahoo! account. The pop3 server is
pop.mail.yahoo.com, and the SMTP server is smtp.mail.yahoo.com. Yahoo!
uses a pop-authentication-before-smtp-relay scheme, to prevent spam
abuse. My user name on my Yahoo! account is 'milanuk'
Previously, I ran RedHat/Mandrake/SuSE, and used sendmail w/ the
install-sendmail script, which made setting things up pretty much
auto-magic. Now I am using Debian 2.2, and install-sendmail doesn't
seem to work on sendmail on Debian.
I use fetchmail in single-drop mode to retrieve my email from
pop.mail.yahoo.com. W/ my previous setup, I would put a line like:
postconnect "/usr/sbin/sendmail -q"
at the end of my .fetchmailrc to run mail sending right after fetchmail
finished, therefore getting around the pop-before-smtp problem.
What I seem to have problems w/ is:
a) getting masqmail to accept mail from fetchmail on port 25. I
installed masqmail, and fiddled w/ the config file, but when I run
fetchmail, it exits saying it can't deliver to port 25. WTF?
b) making sure that my mail is correctly addressed. I send the mail
from ishamael.inet, as user 'monte', and I may use different mail
clients from time to time, but I would like my addresses to get properly
re-written as '[EMAIL PROTECTED]' irregardless of which mail client I am
using.
If someone has dealt with this before, I'd appreciate some help.
Thanks for your time,
Monte

"Joe Public" never configures any hardware. He buys his computers with the
OS pre-installed and takes it into the store when he wants new hardware
installed.
Machines with Linux pre-installed are readily available: "Linux is too hard
to install" is not a viable argument.

Date: Sat, 7 Oct 2000 11:58:07 -0700
About a month ago a group of my friends and I at New Technology High School
in Napa, CA decided to start a small club to learn more about the Linux
operating system and advanced computing. The goal of Linux Club is to take
tens, if not hundreds, of discarded computers and link them together as one
in order to do scientific calculations. The idea sounded easy enough; we had
the technical knowledge and support from the school, but we soon found out
we lacked the funding to complete our project. We determined that we would
need far more computers and networking equipment than what was available to
us. We needed more low-end computers (286 and above), network interface
cards (to help us link the computers together), and networking switches (to
regulate the traffic). These things all cost money and even though our group
has managed to raise funds by heading up the school's recycling and by
having members pitch in their own money, we still don't have all the
equipment we need.
Our club needs all the equipment we can get. What you or any business you
may work for may see as garbage, could do wonders for us. We have access to
a van and we are willing to pick up any computer equipment you might be
willing to donate within the San Francisco Bay Area..
