Use the /proc filesystem. /proc/ide contains information for all IDE
channels and attached devices. You will want to have a look at the files
called "media" (e.g. /proc/ide/ide0/hda/media). These will contain a
string like "disk" or "cdrom".
Also check /proc/scsi/scsi. This file contains information on all SCSI
devices, including the type (e.g. direct-access (normally HD), sequential
(normally tape), CD-ROM, ...).
One caveat however: if you are using something like ide-scsi, some devices
will show up twice (e.g. hda might be listed under /proc/ide/ide0, but it
might also figure in /proc/scsi/scsi).

Daniel

. Here is something I learned about linux that might save other people
time.
If you install Mandrake 7.02 on a drive with more then 12 partitions
plus one extended partition ( I don't know whether or not to count
it as a partition ), it will fail to mount that disk. If that is the
boot disk, it will fail to boot.
RedHat 6.2 will not install on a prepartitioned disk with 13
partitions plus one extended.
I guess the kernel has a fixed size for loading the partition table
and too many partitions causes the buffer to overflow.

Well, both Microsoft's Internet Explorer web browser and Netscape's
web browser do not "support NNTP" (I assume that with "support NNTP" you
mean "have a newsreader"), *in the browser itself*, i.e. the newsreaders
are seperate programs which may or may not be available/installed. Since
IE and Netscape's browser probably cover some 99+% of the users, I would
say "I don't know of any web browser which *does* support NNTP."! :-)

Hi,
this is almost getting me MAD here.
If you're connected to the Net - great.
But if you want to disconnect again (by hand it's like doing a
/etc/ppp/ppp-down) this thing
keeps on redialing all the time unless I switch my modem off by the hardware
switch or pull the
mains plug out of the socket.
I know that it MUST have something to do with 'persist / nopersist' ;
reading the man pages did not have any effect so far, I tried to include the
'nopersist' line
in /etc/ppp/options but this resulted in nothing.
Can anybody help me?
thanks in advance

no
your System.map, vmlinuz and a couple of other files (normally found in /boot)
have to be below Cyl 1024.
SuSE put vmlinuz in /boot as well, this means you can have that as a separate
partition of about 4MB and everything else can be wherever you feel you want
it.
If you go that way, you will need to change the vmlinuz path in your
lilo.conf. You can also uncomment your 'INSTALLPATH' (I think) line in
/usr/src/linux/Makefile
This allows you to do a 'make zlilo' and it lands where you want it to.

The 10101010101 stuff is a clasic indication that you are trying to boot
off of a hard drive on the second controler and your boot drive is on
the primary, or you are having a 1024 limit problem. You might want to
try moving you partitions around and trying anew

A "printer driver" in Linux is a version of ghostscript that knows how to
talk to your printer. You print postscript, and gs translates to whatever
printer language. Or, if your printer understands plain text, you can
print text directly to it just like in the days of DOS.
I doubt that you will find a ghostscript driver for a receipt printer as
that is very much a non-mainstream device. However, I believe that most
of them can print plain text without help. And since you will be using it
from one particular app, you could just get the manual and send the escape
sequences to make it do bold, double width, etc.
For a specialized application like POS, that's probably the easiest thing.

You can upgrade either to RH6.1 or 6.2. There is an upgrade option
and in my experience it works pretty well. I would definitely
recommend it over reinstalling from scratch. But the latter
is always an option if upgrading fails. In any case, you should
back up your user files first. I also usually make a tar
archive of the /etc directory since that contains almost all
the basic configuration files. I have done several
upgrades from 5.2 to 6.0 or 6.1 but not yet to 6.2, but
I doubt if there is any difference. I've done several
upgrades from 6.1 to 6.2.
Here are some potential problems.
If you have limited space in the partition(s) containing
your system files, the upgrade may have problems. A
typical RH6.1/2 system may need something like 760 MB and perhaps
more if you have a lot of packages. If you presently have
only about 1 GB available, I would suggest removing a lot
of packages before the upgrade and then installing them
again from the new CD after the upgrade.
Upgrading from 5.2 to 6.1 doesn't usually add the line
alias parport_lowlevel parport_pc
to /etc/conf.modules although that line is necessary because
of the new way parallel ports are handled. So you may
have to add it manually after the upgrade.
The RH6.1 installer has some bugs which in the case of an
upgrade may affect whether the machine is set up as a dual
boot machine or whether a boot floppy is made during the
upgrade. These bugs have been fixed in updates available
from RedHat Errata or a mirror site. There are also updates
for the RH6.2 installer, but in my experience these are
probably not necessary for a typical upgrade.
I doubt that you can upgrade a RedHat system to Suse, but
I don't really know.

I wish someone would explain why this appears to happen for some

Hi,
I have the following problem on my redhat 6.0 installation with 192 Megs
of Ram :
I want to increase my userlimit for a not root user from 256 max open
processes to 1024 processes.
I have checked with ulimit -u that my current ulimit = 256
On the internet I found that I should compile it into the kernel so I
did the following :
I increased the value of NR_TASKS in
/usr/src/linux/include/linux/tasks.h from 512 to 2048 (for root this
value should be available ,for other users half of this value)
#define NR_TASKS 2048 /* On x86 Max 4092, or 4090 w/APM
configured. */
I also increased the values of
NR_OPEN and
OPEN_MAX
in /usr/src/linux/include/linux/limits.h from 1024 to 4096
#ifndef _LINUX_LIMITS_H
#define _LINUX_LIMITS_H
#define NR_OPEN 4096
#define NGROUPS_MAX 32 /* supplemental group IDs are available
*/
#define ARG_MAX 131072 /* # bytes of args + environ for exec()
*/
#define CHILD_MAX 999 /* no limit :-) */
#define OPEN_MAX 4096 /* # open files a process may have */
#define LINK_MAX 127 /* # links a file may have */
#define MAX_CANON 255 /* size of the canonical input queue */
#define MAX_INPUT 255 /* size of the type-ahead buffer */
#define NAME_MAX 255 /* # chars in a file name */
#define PATH_MAX 4095 /* # chars in a path name */
#define PIPE_BUF 4096 /* # bytes in atomic write to a pipe */
#define RTSIG_MAX 32
#endif
Do I need to set an option in the kernel to true so that these changes
will take effect or ..... is there another catch to it.
I can increase the ulinit for root but not for any user ???
The message I get is operation is not permitted.
I would appreciate any help,

<p>I have the following problem on my redhat 6.0 installation with 192
Megs of Ram :
<p>I want to increase my userlimit for a not root user from 256 max open
processes to 1024 processes.
<p>I have checked with ulimit -u that my current ulimit = 256
<p>On the internet I found that I should compile it into the kernel so
I did the following :
<p>I increased the value of NR_TASKS in /usr/src/linux/include/linux/tasks.h
from 512 to 2048 (for root this value should be available ,for other users
half of this value)
<p><font size=-1>#define NR_TASKS
2048 /* On x86 Max 4092, or 4090 w/APM configured. */</font>
<p>I also increased the values of
<p>NR_OPEN and
<br>OPEN_MAX
<br>in /usr/src/linux/include/linux/limits.h from 1024 to 4096
<p><font size=-1>#ifndef _LINUX_LIMITS_H</font>
<br><font size=-1>#define _LINUX_LIMITS_H</font><font size=-1></font>
<p><font color="#3366FF"><font size=-1>#define
NR_OPEN
4096</font></font><font size=-1></font>
<p><font size=-1>#define NGROUPS_MAX
32 /* supplemental group IDs are available */</font>
<br><font size=-1>#define ARG_MAX
131072
/* # bytes of args + environ for exec() */</font>
<br><font size=-1>#define CHILD_MAX
999 /* no limit :-) */</font>
<br><font color="#3366FF"><font size=-1>#define
OPEN_MAX
4096 /* # open files a process may have */</font></font>
<br><font size=-1>#define LINK_MAX
127 /* # links a file may have */</font>
<br><font size=-1>#define MAX_CANON
255 /* size of the canonical input queue */</font>
<br><font size=-1>#define MAX_INPUT
255 /* size of the type-ahead buffer */</font>
<br><font size=-1>#define NAME_MAX
255 /* # chars in a file name */</font>
<br><font size=-1>#define PATH_MAX
4095 /* # chars in a path name */</font>
<br><font size=-1>#define PIPE_BUF
4096 /* # bytes in atomic write to a pipe */</font><font
size=-1></font>
<p><font size=-1>#define RTSIG_MAX
32</font><font size=-1></font>
<p><font size=-1>#endif</font>
<p>Do I need to set an option in the kernel to true so that these changes
will take effect or ..... is there another catch to it.
<p>I can increase the ulinit for root but not for any user ???
<br>The message I get is operation is not permitted.
<p>I would appreciate any help,
<p>Greetings,
<p>John</html>

The source of the problem with the 1024 cylinder limit is that
current versions of lilo assume the BIOS can only access cylinders
below that limit. So it is not a question of where the lilo
boot loader is placed but where the actual kernel and associated
files are. They should be in a partition entirely below cylinder
1024. This could be a relatively small /boot partition.
But recent BIOS's are in fact capable of accessing cylinders
beyond that limit. Sometimes if you add the linear option
to /etc/lilo.conf, that will allow it to work to boot from
the hard disk. Finally, the latest version of lilo has apparently
removed that limit provided the BIOS is capable of it. It is
not yet available as part of any standard release as far as I
know, but one could install Linux to boot from a floppy and
then get the latest lilo and then run it.
