I may be completely out in left field here BUT <G>.
The 42.42.42.42 has me baffled, why not just plain 0.0.0.0? That 42
stuff would seem to me to possibly screw up some masks.

Subject: Unresolved symbol: module_list
Date: Sat, 31 Jul 1999 14:16:01 GMT
Hi.
I'm writing a kernel module and I need access to module_list pointer.
I've declared it as extern struct module *module_list; , but insmod
gives me unresolved symbol error.
Module_list is declared in kernel/module.c: (kernel 2.0.36)
...
static struct module kernel_module;
static struct module *module_list = &kernel_module;
...
I'm able to access kernel_module, but not module_list.
It's very strange for me, but I'm new in kernel module
programming.Could someone explain it to me?

The include/linux/version.h file is built during the kernel build.
See the top-level Makefile. You can also see there how the
LINUX_VERSION_CODE is determined.

It's not that simple. By the time you've established that the last
thing is 'ready', the first thing may no longer be. And by the time you
can retest everything, nothing may be ready anymore. Though I think this
is pretty much useless, it's not easy to emulate. The best solution is
to rearchitect so that you don't need it.
The POSIX/UNIX way and the WIN32 way of a lot of things are very
different. The way to port is to find the right level of abstraction in
your program and draw a line. Recode everything below the line for the
new platform. If you code is well structured, this won't be unduly
difficult.

Is there such an animal ?
Unixware has their 'Webtop' interface that allows system management with a
web interface, and Samba has it as well, I'm looking for the ability to
manage a linux server from a remote browser (or even a local browser
although that makes less sense as you are in X and presumably X management
tools are available) I have a number of application servers that do not
have X installed, and a couple that do, my 'desktop' machine is actually a
laptop running WinNT, and I run a windows X-Server to connect to those
machines with X running, and telnet into the others to do sysadmin tasks. I
have been experimenting with perl and have created a script to do the most
common task (add/mod/del users) with a web interface, and am thinking of
expanding it to cover more tasks, but don't want to reinvent the wheel.
Any feedback would be appreciated.

I know of two such beasts: linuxconf and webmin. You'll find them via
freshmeat.net.

I have a newly aquired Compaq 5133 and I am getting the following error:
apm: busy: Parameter out of range
These error occur when the screen is blank. When I press shift to
redisplay the screen, most of the time the screen goes blank again.
I am new to linux but traced the error back to the apm.c.
Is this a known problem with my machine and can I set parameters to
avoid this or do I have problems with my machine?
If it is a parameter setting, could you please be explicit in your
explenation or tell me where there is a good explenation since I am new.
Thanks, wes.

There is a RedHat-CD-HOWTO (or mini-howto) on the LDP sites which include a
section about how to create a CD with the updates integrated; I think that's
exactly what you need. It has a few shell scripts for doing exactly what you were
attempting (replacing the files, plus updating the installation database to use
the new RPMS). I have used them for integrating the updates to installation CDs
(both 5.2 and 6.0) and they worked.

I would suggest that it's even more expensive to buy on the newsstand
than you think.
By going onto the newsstand, that forces the "advertising pressures"
to a head, because it reduces the proportion of the revenues from
sales that the magazine gets.
After all, someone's paying for the costs of moving magazine from
Seattle to your local newsstand, as well as the profits taken by both
the wholesale distributor and the newsstand...
This is a case where the free market:
a) Isn't all that free, as the magazine wholesalers are a very small
population, and very close to a monopoly, and
b) Doesn't very well defend "quality content." The free market
*really* defends the notion of maximizing revenues/profits. Quality
is not at the top of the list of things that it encourages, sadly...
