I took the Unix system administration exam and passed with 100%. Took the
TCP/IP exam and failed with 37%. =p~ Only thing that's weird to me as there was
only 7 questions. It's far from a nationally known exam center (such as A+,
MCSE, CISCO, etc) but it's got lots of neat features such as a free
certification paper when you pass, your name on the list, etc.
Hey, for free, why not?

This is true in certain instances. If your previous kernel didn't have
any sound support, and you did a "make menuconfig" and set up sound
support to be compiled directly and SB16 support to be a module, you'd
have to recompile chunks of the kernel. However, modules are just
that--modular! Generally, the kernel obtains the hooks it needs from the
module itself, or from other modules.
For instance, if you try to modprobe the SCSI Generic module and there's
no SCSI support compiled in, the /lib/modules/X.Y.Z/modules.dep file will
be consulted. Then the kernel will know to load the SCSI host adapter
module, then the SCSI module, then the SCSI generic module. Similar
arguments apply for most other things.

Not really, but there was a time when I was compiling and tweaking kernels
every other day (motherboard was badly br0ken and I didn't know it--tried
to fix a hardware problem in software), and I ran through many compiles
without doing "make dep" or "make clean" and things worked, sort of. (No,
they didn't work any better with "make dep clean" included. Flaky
hardware will do that.)

Not sure, but if all else fails, you could always load it in

Just write a script to do what ever you want to do, make sure it is 755
permission and symlink it to /etc/rc.d/rc#.d/99scriptname where # =
runlevel. For example rc3.d runlevel 3 and rc5.d is runlevel 5.
For example here is a script that runs vncserver as user efflandt (the cd
and PATH is because I have not figured out how to su a program as a user
with the users environment like su -). You don't need '&' ending
commandline if your daemon automatically forks to the background like
vncserver does:
#!/bin/bash
cd /home/efflandt
PATH=/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/games:/home/efflandt/bin
/bin/su -c /usr/bin/vncserver efflandt

In my case it insisted on detecting the (external) modem. I disabled kudzu
because I got tired of having it interrupt the boot process to ask me
questions when the modem was on(off) whereas it had been off(on) the last
time I'd turned the machine on :-)

No. However, there will be less disk access when in the console instead
of gnome.
For one thing if you have gnome set to automatically mount CD's it
regularly polls the CD drive to see if a CD has been inserted. Linux also
does not write to the disk immediately, so kflushd flushes the buffers to
disk occasionally. There are also system logs, atd, crond, etc. that sort
of make it almost impossible to spin down your primary drive.

Make sure that the kernel source been configured at least once. If you
are using the source straight from the installation for either
Redhat or Mandrake, you can just run the configuration once and save
it.

The thing to do is to put the appropriate options in /etc/conf.modules
. That way the module can be loaded on demand. If the module is for a
sound device, you'd insert something like the following lines:
alias char-major-14 foosound
options foosound irq=5 io=0x240 dma=2 dma2=5
Or you can just tack the modprobe command on to the end of
/sbin/init.d/boot.local (SuSE) or /etc/rc.d/rc.local (RedHat).

What do you mean by "in init.d"? As before, you can put the command
directly into boot.local ("/path/to/mydaemon &") or you can create a start
script in /sbin/init.d/ (/etc/rc.d/init.d/) like the other scripts there,
then put in both S and K links to that script in the runlevel directories
/sbin/init.d/rcN.d/ or /etc/rc.d/rcN.d/ . Consult the scripts in those
locations and/or the README residing there for more info....

You cannot run ntpdate while xntpd is running. But I have only used
ntpdate (and not xntpd) so I am not sure how to set up xntpd. Do you have
multiple stratum 2 time servers listed in /etc/ntp.conf so xntpd will
still work in case one is down or busy?

According to the version 2.x manual:

Under OS/2, PartitionMagic must know the drive letter for each partition
before modifications can be made. A driver on your system may change the
drive letters from their defaults; or your partitions may not have serial

Alternitavely, leave it exactly where it is and make that m upper case ;).
ie

otherwise it won't work.

Reply-To: [EMAIL PROTECTED]
Date: 7 Jul 2000 20:02:14 +0100
[excuse crosspost -- dunno if its technical enough for development.system.
apols if off-topic].
Hiya,
I have a problem - one that I've been unable to find an answer for in
several hours of on-and-off experimentation and numerous kernel builds.
There is, at work, a Dell Poweredge, Dual PIII 450, Megaraid RAID, bags
of memory and disk etc etc. But I've been unable to get modules to insert
into the kernel, with messages from insmod "unresolved symbol". The system
is a RedHat 6.1 Deluxe installation...and its the supplied Redhat kernel.
Personally, I'd like to blow it away and stick a stock non-vendor-modified
2.2.14 on it, but I've been told not to do that... *sigh*.
Here is, for example, the output of "insmod loop":
/lib/modules/2.2.13-0.13/block/loop.o: unresolved symbol best_memcpy
/lib/modules/2.2.13-0.13/block/loop.o: unresolved symbol best_memset
/lib/modules/2.2.13-0.13/block/loop.o: unresolved symbol best_copy_to_user
/lib/modules/2.2.13-0.13/block/loop.o: unresolved symbol best_copy_from_user
Now, from what I can tell, these are standard kernel functions, and whats
more, "grep best_mem /boot/System.map" reveals ...
c0220384 T best_memcpy
c022040f t best_memcpy_final
c0220437 T best_memset
c02204bf t best_memset_final
c0265fe0 ? __kstrtab_best_memcpy
c0266000 ? __kstrtab_best_memset
c026d7b0 ? __ksymtab_best_memcpy
c026d7b8 ? __ksymtab_best_memset
So its in the kernel...however, I'm wondering if there is some obfuscation
going on somewhere, as doing ksysms -a and feeding that through grep reveals
c0220384 best_memcpy_R__ver_best_memcpy
c0220437 best_memset_R__ver_best_memset
Both at the same offset as the output from System.map ... is this causing
the problem -- same symbol but different name ?
Basically, module loading is broken and I can't figure out whats gone wrong.
Yes, I've done from clean, zapped the modules tree before a make
modules_install.
depmod -a fails everytime (unresolved symbols in every module), so its well
and truely fubar'd.
Suggestions on a postcard?
Thanks,
Chris...

I tried to hack httpd from apache which is a script in
/etc/rc.d/init.d/. In rc{1,2,...}.d are symlinkks to this script.
Because my program is not a background task I have to use & in the
line:

daemon myprog &;
and this doesnt seem to work. :-(
