Hi!
Recently I installed suse 7.0 including the kernel-sources,
I selected a standard pentium-optimized kernel.
I wanted to recompile though (just for the sake of it):
After I recompiled (make mrproper, make xconfig, make dep,
make clean, make bzImage, make modules, make modules_install)
I moved the new kernel into the /boot
directory and added a new entry in the lilo configuration file.
I did not select any option as a module, except for the
sound option (I have a sb-live) without any device selected
(as is specified by the emu10k1-readme).
When I booted I noticed the following error message;
mounting local file systems
mounting /dev/pts.modprobe:modprobe;
can't locate module devpts
mount fs type devpts not supported by kernel
I looked into the modules.conf but I can't find a
direction to /dev/pts or anything. I also checked
the xconfig again
My questions;
What is /dev/pts?
Where can I find the corresponding option in xconfig (kernel)?
thanx in advance,
och

I concur, bad sectors occurring on modern drives spells failure on
the horizion. Backup everything and secure a replacement. Check

Subject: Need help with library files, Do I have the right version?
Date: Tue, 19 Dec 2000 13:22:47 GMT
I have RH7.0.
I'm getting started to re-compile my kernel. I have untar'd the new
Kernel and am doing the version checking in the Changes file. The 4th
and 5th lines are about the C Library file, it says:
- Linux libc5 C Library 5.4.46 : ls -l /lib/libc*
- Linux libc6 C Library 2.0.7pre6 : ls -l /lib/libc*
Whe I execute the ls -l /lib/libc* command, here is my out put:
-rwxr-xr-x 1 root root 4776568 Aug 30 16:56 /lib/libc-
2.1.92.so
lrwxrwxrwx 1 root root 14 Oct 6 01:18 /lib/libc.so.6 -
> libc-2.1.92.so
lrwxrwxrwx 1 root root 17 Oct 6

lrwxrwxrwx 1 root root 18 Oct 6
01:18 /lib/libcrypt.so.1 -> libcrypt-2.1.92.so
My question is, I don't see anything about libc5 or libc6, do I need to
install some library files? If so, where can I find them? When I
installed Linux, I did a custom and chose the development tools.
Thank you.

Subject: GNOME freeze on RH7.0
Date: Tue, 19 Dec 2000 13:30:47 GMT
Hello,
I recently installed RH7.0 on a machine. While it was being used by a
dozen people over the network and serial ports, I had invoked X-Window by
entering 'startx' as root from tty2. Well, the virtual terminal switched to
tty7 and GNOME started. But nothing at all appeared in the taskbar (it was
just a solid gray bar at the bottom of the screen). The background
"wallpaper" was there as well as the desktop icons and looked OK.
The mouse pointer was also there and controllable by me (I could move it
around). But nothing would happen when I clicked on any icons. And because
there was nothing on the taskbar, I could not exit GNOME. Even worse, I
could not change screens - I was completely stuck in tty7. Luckily, I was
able to 'su' on one of the serial terminals and kill a bunch of X tasks
until I finally had control back on the main console.
What happened here? Is there any other way to exit GNOME when stuck like
this, and has it happened with anyone else? It was the second or third time
that I had opened GNOME that day... it worked fine before that incident.
Thanks in advance,
Scott Navarre

Do you run WINE? I think some of the more straightforward win95 editors
like Goldwave will run under it. I haven't used it in anger, but when when
I was playing with WINE I managed to get it running. I can't now check
this for you since I have reinstalled my system and not yet installed WINE
again.

Subject: RH7.0 WvDail and external modem disconnects?
Date: Tue, 19 Dec 2000 13:38:38 GMT
Hello,
I am having trouble keeping a external USR Sporster
connected to my ISP. I get connected, validated and
can hit some web pages but the connection shutsdown
within 2 or 3 minutes.
Kudzsu picked up the modem and configured the init
string as:
ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0
While both ends should be doing v.90 56Kb, I'm out
in the boonies and have never gotten my NT machine
to do better than 28.8K. That would be great if
the RH7.0 box would just stay connected?
Could anybody suggest some Init tweeking that would
help?
Thanks,
Bill

Hi,
I just want to submit you a little problem :
I can't ping any host on my LAN with a RealTek 8029 adapter under Mandrake
7.2.
Here are the symptoms : configuration is OK through netconf or DrakConf. But
when I try to type an "ifconfig eth0 xxx.xxx.xxx.xxx ...", system replies
"Ressource temporary Unavailable".
I can ping myself, but I can't see any other Win98 hosts with fixed

What's the matter ?

May I ask you about the source of your information? I consider it not
quite correct. Neither do FAT variants _require_ defragmenting nor do
others like NTFS or ext2fs not. (Nor is fragmentation
platform-dependant.)
Fragmentation occurs on any writeable filesystem and reduces
performance. The amount of fragmentation depends on the complexity of
the fs (VFAT < ext2fs < NTFS4) and the strategy (cleverness) of the
underlying OS to keep fragmentation low (strategy: ext2fs > NTFS4 >
VFAT). Though ext2fs tries to avoid some fragmentation, it can't succeed
entirely. So using defragmentation tools is clearly not a bad idea,
though their use isn't _required_ on _any_ system. I personally do use
'e2defrag' and can confirm considerable improvements.
Have a nice day.

On top of the other recommendations, you could do worse than get hold
of a copy of 'Soul of a New Machine' by Tracy Kidder. Kidder is a
tech. journo and was sort of writer in residence while DG designed and
built the Eclipse, their first 32 bit minicomputer. Its both
informative and a good read. I don't know whether its still in print,
but there are lots of copies at Alibris (www.alibris.com)

1) ensure that there are no users logged on, and that you are logged
on as root ('telinit S' should do it)
2) Allocate a partition (fdisk, etc.) for your new /home directory
3) format the partition with mkfs.ext2
4) mount the partition under the /mnt mountpoint (say /mnt/home)
5) copy the entire contents of the /home directory tree to your
new partition (the Tips-HOWTO recommends a tar pipeline that looks
like... (cd /home && tar cf - . ) | (cd /mnt/home && tar xvfp -)
Up to this point, we haven't done anything that will impact normal
operations; you can quit here if you get nervous.
6) edit your /etc/fstab to include a line to mount the new partition
at the /home mountpoint. Assuming /dev/hdb2 is the partition,
the /etc/fstab line will look like...
/dev/hdb2 /home ext2 defaults 1 1
7) remove or rename the /home directory
rm -rf /home
or
mv /home /home.old
8) move the new home directory into place
mv /mnt/home /home
9) change back to multiuser mode
Done.

> Does anyone know the difference between the memory used for BUFFERS

I'm not quite sure, but the basic idea seems to be, that data blocks
which are originally read from disk should go to the "cache". Data which
has lately been written to disk should be kept in "buffers". The sum of
both is the amount of data which actually occupies unused RAM to try to
accelerate "harddisk accesses" (actually avoid physical harddisk
accesses).
You can watch this, for example, by doing 'dd if=/dev/zero of=/tmp/zero'
which behaves like a write-only operation (don't forget to remove
/tmp/zero afterwards ;-) ). This increases the amount of buffers and
decreases the amount of cache (when free memory is going low). Insteqd,
heavy reading of files from the disk should increase only the caches.
Nevertheless, there seem to be some exceptions (bugs?) which I don't
really understand. For example, contents of directory blocks which are
read seem to be stored in buffers rather than in caches - even when I
turn off ATime updating. Can anyone explain this to us?
Hope to have helped you a little.
