Include the libm library (-lm) because for some reason the math
libraries are separate from the other standard libraries (libc) and
libc is automatically included during compile if needed.

Add -lm to the compile line. This links in the math libs.

A quick note: If they ask you what OS you're running you might want to
say you have a Mac (which also needs to be told the DNS addresses).
Some ISP's won't talk to you if they know your trying to run
Linux/Unix (Don't know why) but most will support a Mac.

you need to link the math libraries during the compile. you can do this
as follows.
gcc filename.c -o filename_out -ml
that SHOULD work.

Actualy it is much more simpel. The lilo program creates a file called
/boot/map, and this file contains a list of sector addresses for each
sector of each file it neads to load. Thus, lilo needs no knowlege
of file system type partition boundaries, or root file system address.
The lilo boot sector then contains the sector address of /boot/map so
it can be loaded into memory.

Subject: Syslog problem
Date: Tue, 5 Sep 2000 09:49:53 +0200
Hi all,
I know I already send a post on this subject, but I have new informations !
The goal : setting up a bootable CD-ROM based on RedHat 6.2
The problem : syslog does not log !
When booting, syslog is launched by the init scripts and does not log
anything except "Syslog restarting ..."
If I just launch it manually after the boot, it will work.
I modified the init scripts to launch it without a special daemon calling
function, does not change anything.
The interesting part : I made system call traces with strace and found :
- syslog opens /dev/log as a SOCK_DGRAM socket,
- loggers ("logger" for example) can't open /dev/log socket : get a
EPROTOTYPE error when opening with SOCK_DGRAM.
I think this is most of the problem but can't find solution.
Note : I boot the system with a read-only root fs and a ramdisk over /var.
Kernel is 2.2.16 patched with devfs. When rebooting with a read-write root
fs, I have no problem at all !!
I don't think there is a user right problem as /dev/log is created 666 by
syslog.
I someone could help about this problem, I just have no more ideas ...
Thanks in advance.
Sylvain.

You've looked at the major places. Often (or at least sometimes) the
name of the library file itself has little in common with the name of
the software package that it is included with, so you can't really say
"Aha! I need the 'libXmu.so.6' library, so I should probably download
the 'Xmu' software package!".
The packaging system of Debian GNU/Linux (and GNU/Hurd) has a nice
feature. It lets you see what package any given file on your system
belongs to. On The Debian site, at [1] under "Search the Contents of
the Latest Release", try searching for your library. if it is
available in the Debian system it will answer with a package name. The
package name will give you a clue about what you need to look for
(searching for e.g. 'libXmu.so.6' returns ' the 'xlib6g' package and
that package is available in source form by searching in another
interface at [1]).

It's crashed 3 times in the last 24 hours. Total lockup, requiring
calls to a service engineer to reboot it and too much downtime to keep
our customers (or my boss) happy. I'd like to know if there are any
DoS attacks which might cause the failure, or any other exploits I

I trying to recompile my kernel to include AppleTalk but when I reboot
it resorts to using the old kernel. I�ve listed below exactly what I�ve
done�.3 times now!!
In /usr/src/linux-2.2.14 I type �make xconfig� and add the AppleTalk
option to the kernel save and exit. I then type;
make dep
make clean
make
make modules
make modules_install
at which point I have an executable file called �vmlinux� appear in the
linux-2.2.14 directory. I then type;
make zImage
and then a file called zImage appears in /usr/src/linux/arch/i386/boot/.
I copied this file to /boot where the existing kernel is and then
edited the /etc/lilo.conf file to the new kernel;
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=linux
image=/boot/zImage
label=linux
read-only
root=/dev/hda6
But when I reboot and type �uname �v� the kernel date shows up as Tue
Mar 7 2000 and �dmesg |grep appletalk� shows nothing.
What am I doing wrong?

Yeah, well, somehow I'm not entirely surprised.
The few occasions I've tried to make / readonly, I've regretted it.
Needs mods to mount and umount for one thing. It probably is feasible
if you start off rw and ro and some later stage, after replacing
/etc/mtab, /etc/motd, /etc/issue and friends with symlinks to /var.
The real stinker is /dev.

After the installation of the new kernel you must also
update LILO typing "lilo" at the prompt. This will update
the boot sector.
It's not recommendable to install the new kernel as the
default one without keeping the old one around. What happen
if, for some reason, the new kernel does not work ?
Install the new kernel under a different label and call
it during the LILO boot. This way you can test the kernel
before make it the "standard" one without trouble.

It could be your monitor settings. If you chose generic monitor, the horiz
and vert ranges will be less than what your monitor probably is. Generic
will give low resolution. You can either manually edit /etc/X11/XF86Config
and put the correct Horiz and Vert ranges in the Monitor Section or you can
run xf86config and choose to write in your ranges, or you can run XF86Setup
or Xconfigurator and choose the ranges that are closest to yours. All this
of course is if your monitor is not listed in the monitor database.
In fact it could be that you just have not run a configuration program at
all and need to do that.

Hello everybody,
we are using several linux servers (file, communication etc.) here at

communication and workflow management.
As we will continue to have certain servers on Linux for some time it
would be very nice to have user authentification just in one place.
What I would like to have is editing users only in the Lotus Notes system
and having all other Linux servers access the Domino user database for
authentification.
Can this be done using Dominos LDAP? Or is there any other chance to have
user authentification just in one place with several Linux boxes and a
Domino server (running on Linux also)?
Thanks for your suggestions.

do you have a link /usr/src/linux --> /usr/src/linux-2.2.14 ? You should have
one. All the makefiles assume the source tree in /usr/src/linux

I don't know what zImage is. I use bzImage, that works. You can make bzImage
right after the make clean, instead of just make.

I guess you just recompiled the old kernel in the /usr/src/linux tree. Rename it
to /usr/src/linux-orig or something. Do a
ln -s /usr/src/linux-2.2.14 /usr/src/linux
And, don't overwrite the old kernel in case the new does not work ! Leave it in
/boot/vmlinux-orig and update the lilo.conf to have two images. Copy your new
kernel to /boot/vmlinux-appletalk or something. Let lilo.conf know of both
images. If the new one does not work, you can still boot the old one.
