And if you want a second opinion, my advice is to get an O'Reilly book.
I'm reading "Running Linux" ($30 ca.) and though I'd been using Linux for
a year before I even got the book, there's just a lot in there that I
wouldn't ever have found out on my own. Web-based references are nice,
but sooner or later you'll probably need to pick up a more in-depth guide.
Originally, I didn't want to buy any books myself, but now that I have them,
I think they're wonderful-- It's my bed-side reading every night (which is
why I haven't been getting to sleep before 3am lately :)

Date: Sun, 05 Nov 2000 08:58:05 GMT
Hi out there...
I recently installed kde2 (from suse.de). It looks very nice, it is
inituitive etc. but I got a problem with stability. Konqueror crashes often,
xmms freezes when playing the first song (after about 30s it will start to
play). When I'm running the demos from lokisoft.com, the whole X-Server
crashes (which is probably a problem of these ugly nvidia-drivers). However
kde 1.* seems to be a lot more stable to me. Is this a general phenomena or
is it my configuration?

GNOME is effectively just a set of widgets that run under X. It will
not affect any application that uses OpenGL directly with X11 or glut.
Also, the GTK toolkit that underlies GNOME provides a widget (gtkglarea)
that provides a display buffer into which OpenGL rendered images can
be displayed.

Yes, and, after you get that going your way, implement NTP. It's simple
to install, and will be the end of issues involving the right time on your

I did a "make bzImage", and took a look at the install.sh script that
copies bzImage to $BOOT/vmlinuz, renames the old kernel and calls lilo.
It does all that, except that lilo fails. For some reason Linux now
thinks that the disk has CHS 8709, 64, 32. I have a 2nd
(identical) disk that fdisk reports as having CHS 1110, 64, 32.
Looking at the partition with Partition Magic 4 (Windows) the only thing
it doesn't like is the type 5 extended partition (Windows prefers type F
on large disks). An older version of Partition Magic (2) gives an error
110:
Error #110 - Partition table number of sectors is inconsistent
The hard drive partition table contains erroneous values. The partition table
contains two size descriptions which do not agree.
This error can occur if DOS and OS/2 disagree as to the apparent geometry of
the drive.
This error is serious if the drive is used by both DOS and OS/2. DOS uses one
of the size descriptions and OS/2 uses the other. Data loss is likely once
the partition is almost full.
DFSEE (probably the most verbose disk analyzer in the world) doesn't
find much to complain about: one unformatted partition, partitions not
reachable from DOS INT13 and 2 bootable partitions that are not on disk
1. For Linux I get
Warning: FS-type 'EXT2' does not match bootrecord info: '��������'
I get similar things for FAT32 and Solaris.
That's for my 3G ext2 partition in a DOS extended partition.
What a pain!

This is a "good thing [TM]".
Allowing root access via telnet can be a serious security flaw, as it allows
people from the outside to attack your system when you're connected to the
internet.
In fact, you shouldn't REALLY use telnet if you intend to become root at
all. (All text transmitted is unancrypted, so packet sniffers may be able to
sniff your root password).
ssh solves these problems.

Did you `su -` before creating the new user? User management is a root
privalige.

Don't. Use ssh to gain access to your system as a different user and then
use su to change to user root from that account.

Probably.
FTP normally defaults to active mode. In this mode, your machine establishes
a connection to the remote machine, and then the remote machine attempts to
establish a connection to yours. This is where the firewall gets in the way.
There is a passive mode... Just activate it by typing "passive" at the FTP
prompt, then see if you can download something from an FTP site in passive
mode. If you can, it's an active/passive mode problem.

Only root can modify an IP Chain, so either supply your acquantance with the
IP Address of the FTP server you need (he could then add a rule to allow ftp
through from that site), or settle for passive mode.

Subject: Is there a reliable GUI ftp client for Linux?
Date: Sun, 05 Nov 2000 14:36:14 +0100
Hello,
is there a reliable GUI ftp client for Linux? I'd be happy about any
recommendations.
Unfortunately, all GUI ftp clients I've tried so far are simply not
reliable enough:
- gFTP 2.0.7b - has major problems with windows-based ftp
servers (G6, WarFTP), therefore unusable for me
- gFTP 2.0.7a - works with these servers, but the timeout
feature doesn't work, therefore unusable for me
- IglooFTP PRO - great functionality, timeouts work, but
not stable enough - crashes very often, every 5-10 hours,
therefore unusable for me
- DeadFTP - doesn't work with my distribution, because it
requires newer libraries (I'm using Debian 2.2).
I'm wondering, is there any GUI ftp client that will work as well as the
good windows ftp clients (e.g. Bulleproof FTP)? Doesn't have to be
freeware, I'd be willing to pay for it if it's really good. E.g. I would
buy IglooFTP Pro if it wouldn't crash so often.
bye,
Till

I'm running KDE2 on SuSE 7.0 using the KDE2 rpms from the SuSE ftp site.
KDE2 is running very well, as is xmms. The only app I can run on KDE2,
so far, is MuPAD-1.4.2, which seg faults when the graphical help attempts
to load.
I had intially attempted to install KDE2 using SuSE rpms from SourceForge
but had serious stability problems with them.

The c/h/s reported by the bios is the c/h/s reported by the bios. It's
a fact. You can tell the kernel to disregard it and use a different
c/h/s instead (but nobody will use it except fdisk and lilo, since
nobody makes bios calls). Or you can change the bios to report a

Right. What would be more helpful would be an explaination as to why
the FAT file system (MS-DOS/MS-Windows file system) both does fragment
(which is not in *inself* bad) and why a fragmented FAT file system is
bad, *partitularly* in the context of MS-DOS & MS-Windows.
The simple / short explaination has to do with the fact that the FAT
file system uses a *simple* linked list. Linked lists are notorious
for fragmentation -- which is a major problem with LISP systems under
memory-starved conditions -- they tend to page fault all over the place
after things are running for a while. This is *exactly* what happens
with the FAT file system. Note: fragmentation itself is not really
bad, if the operating system is designed to cope with the fragmentation
*intellegently*, which usually means things like smart cacheing and
various sorts of file system 'look ahead' / 'read ahead' features,
which MS-DOS & MS-Windows generally lack (MS-DOS lacks these features,
as does MS-Windows 95, 98, and ME -- 'NT and 2K are a little better).
Note ext2 does fragment some, but both the ext2 structure and Linux
itself are *designed* to cope with the fragmentation in an intellegent
fashion and not suffer performance degradation because of it.
The FAT file system was originally invented for *floppy disks*, which
are relatively low capacity and where there is not really massive file
creation and deletion. Also floppies are slow (in a relative sense) and
don't have the spare sectors for a more complex file system. (Linux
people tend to use the FAT filesystem for floppies, since Ext2 has too
much overhead for floppies). Fragmentation on a floppy is easy to cure:
copy everything off the floppy, reformat it and copy everything back.
Actually floppies tend to wear out before fragmentation becomes serious.
Or else the files on a floppy are 'static' (they are backup copies).
