What version of Red Hat?
I tried it with Red Hat 7.1 and "printconf", which is the printer
configuration tool for Red Hat 7.1, and there is an option for HP
LaserJet 5P.

Assuming you have installed an IDE ZIP (not a parallel port or USB
one), and say you have installed it on the secondary ide interface of
the second controller, then it will show up as hdd4 (older models) or
simply as hdd. Now make a symbolic link to the zip drive,
cd /dev
ln -s hdd4 zip
And tell your system that it needs the ide-floppy driver for the zip,
add the line
alias /dev/zip ide-floppy
to your modules.conf (Oops, that might be conf.modules in redhat 6.2),
and do
depmod -a
and then try to mount it somewhere with the mount command.

How are you trying to start it? Which distro? To run an NFS server,
you need to start portmap (typically /etc/init.d/portmap start) and
then nfs (/etc/init.d/nfs start). You also need to allow portmap
from the server and clients in /etc/hosts.allow.

POD's could also be formed by broken network cards, in which case
a $20 piece of hardware could bring down a $multimillion network.

All of this reminiscing reminds me of the interesting bug with
the Aegis anti-missile defense. The system consisted of dual
batteries of twin gatling guns slaved together with computerized
fire control. The batteries were designed to defend against the
nearest threat. Someone found out you could defeat the system by
flying right down the middle between the batteries - each gave
way to the other. That, at least was a simple fix, they
thought, we'll simply have both batteries attack. So the next
countermeasure was to follow one missile with another from a
different angle. After that they decided the programming needed
to be a bit more intelligent.

1. RAID doesn't improve performance, it degrades it.
Some forms of RAID provide redundancy at the cost of performance, some
increase size by combining disk drives, which has no effect on
performance.
2. If you have a 30GB with Windows installed on it, and an empty 30GB
disk, I would install Linux on the new disk.

Subject: Can't get program to run from inetd
Date: 23 Apr 2001 14:40:21 GMT
I'm trying to get a small Perl program (/etc/kdttest) to run from inetd:
#!/usr/bin/perl
while ($line=<STDIN>)
{
chomp ($line);
print "You said: $line\n";
if ($line eq '.')
{ exit; }
}
I can run this program interactively and it works as expected (permissions
set to 755). I have tried all of the following but nothing works (sorry
if some of it wraps). In the actual files, I have not indented the lines;
I have done that here to make it easier to read:
1. In /etc/inetd.conf:
62010 stream tcp nowait root /etc/kdttest
2. In /etc/inetd.conf:
62010 stream tcp nowait root /usr/sbin/tcpd
/etc/kdttest
3. In /etc/inetd.conf:
62010 stream tcp nowait root /usr/sbin/tcpd
/usr/bin/perl /etc/kdttest
4. In /etc/services:
kdt1 62010/tcp # Testing
and then in /etc/inetd.conf:
kdt1 stream tcp nowait root /etc/kdttest
I then completely kill inetd and run it again. This is what
I get in /var/log/messages:
Apr 23 15:30:39 thorin inetd[31597]: 62010/tcp: bind: Address already in
use
However if I take the one line out of /etc/inetd.conf and restart
inetd I still can't telnet on this port so I can't understand why
the port is already in use.
I have spent quite some time searching for info on the web for
this but cannot find anything. Am I doing something stupid?
Cheers,
Kingsley.

Well, in a non-switched network, they still can, just by causing
electrical trouble.
At least I used to have a card that, since a storm, would collapse
any 10-base-t network you put it in, I used it as an example in courses.

Sorry Peet, but I'm not even going to attempt to give you a cut & paste
answer to your dillema here, I haven't had to use SLIP and/or PPP since the
about the time of the 1.3 kernel so I'm not too sure what has changed.
The short answer is yes, it is quite possible. What has to happen after you
run 'ppp' on the server is you need to start 'ppp' locally, the two ends
initiate a 'handshake sequence' to determine your ip, gateway, dns's, mtu,
etc.
The normaly way of doing this was to use a script to feed to 'chat' that
would dial in, make the connection, then start ppp on both ends.
For specifics, please go to http://www.linuxdoc.org/ and read the PPP HOWTO
( http://www.linuxdoc.org/HOWTO/PPP-HOWTO/index.html ). I'm sure someone
has developed some nice 'X' front end to make the setup easier, but I can't
say for sure which one is best.
Perhaps someone who still uses a modem can give you some specifics.

Nearly any language can be used: C, C++, Perl, Python, Tcl, Java, ...

They are "toolkits" (i.e. libraries) to make programming X applications
easier and to give applications an unified look and feel. The KDE desktop
is based on QT and Gnome is based on GTK.
For VC++/MFC programmers the easiest way to approach Linux programming
is (IMHO) QT/KDE using KDevelop.

So i tried to install the alsa drivers for my soundcard (ensonique 128)
and it worked for a while, and then i did a kernel recompile to get scsi
elim working, and now im having a terribly hard time with the drivers.
basically ive stripped down my kernel so right now just the es1370.o is
the only sound driver, and its loaded as a module... however when i try
and do a
modprobe es1370 i get these errors:
/lib/modules/2.4.3/kernel/drivers/sound/es1370.o: init_module: No such
device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
/lib/modules/2.4.3/kernel/drivers/sound/es1370.o: insmod
/lib/modules/2.4.3/kernel/drivers/sound/es1370.o failed
/lib/modules/2.4.3/kernel/drivers/sound/es1370.o: insmod es1370 failed
any idea as to why? all i want is my sound to work :-( what can i do!?!

I would suggest using one of the configuration utilities that come with
Mandrake. Manually configuring chat is a real problem.
The KDE modem controller is relatively easy to set up as is the rp3 package
that comes with redhat (but I don't know if it's included with Mandrake)
If you specifically don't want to use the graphical tools, you could try
wvdial or diald

You don't have an es1370.

Put in the right driver. Perhaps you have an es1371 or 1373? Doesn't
alsa have drivers for this?

Show us a command that you type and the error message it gives you. If
there are no explicit error messages, then describe the precise nature of
what you consider to be the failure.
Only then we can begin to help.

What? Common sense, practical experience, and benchmarks all prove that
wrong.

I think that you're totally confused. You're thinking of the hacks that
simply start writing at the first of one disk, fill it up, then start on the
second disk. That is not how most RAID arrays work. In a RAID 0 array,
when you write your data, it is split up and parts are written across all of
the disks. When you go to read that, since the drives are working in
parallel, there is a higher throughput than a single drive.
Now if you're talking about an IDE RAID setup, things get a little
trickier, because IDE wasn't designed for multiple devices, and has a higher
CPU usage than SCSI drives. However, with two drives, one on each IDE
controller, overall performance is definitely increased.
The one area where performance can suffer is in writing data under
certain RAID levels. Under RAID 1, there is a small performance hit in
writing. In RAID 5, there is a bigger hit, as checksums must be computed.
A lot of people will say "write performance sux under raid 5, dude!", but in
my experience, that's not true. Even a relatively small SCSI RAID array can
*write* significantly faster than a good IDE drive can *read*. While it's
not as fast as it would be under RAID 0, that's still pretty good write
performance.

Subject: fdopen error in libc.so.6
Date: Mon, 23 Apr 2001 11:54:33 -0500
Hello,
I've encountered an error that's got me stumped. I'm running Red Hat 7.0.
All of a sudden, with *no* changes to the libraries that I know of (classic
denial there), I've started getting errors:
$ rpm -qa
/usr/lib/rpm/rpmq: error while loading shared libraries:
/usr/lib/libz.so.1: symbol fdopen, version GLIBC_2.1 not defined in file
libc.so.6 with link time reference
$ ftp 192.168.1.1
ftp: error while loading shared libraries: ftp: symbol fdopen, version
GLIBC_2.1 not defined in file libc.so.6 with link time reference
Those are two examples. I can't do inbound ftp, either. Once I
authenticate, the ftp service disconnects (obviously due to the same error
as above, I'd say). If I reboot the machine, I can run, for example, "rpm
-qa" a few times. Then bang--no more, with the glibc error. I have no
idea what's up here. Can anyone help?
Thanks very much,
Dan
