You don't need to join the domain to use the Internet, only to access NT
server shares.
To access the Internet you need:
1. The IP address of a DNS server (which you may have obtained by dhcp.)
Look in /etc/resolv.conf
and see if there are any nameserver lines. You can get the correct
values from a Windows box by
going into Control Panel->Network->TCPIP->Properties->DNS. While you are
in there, check the Gateway
tab for the IP address of your router.
2. A default route. Type 'route' and see if there is an entry for
'default' pointing to your router. If
there isn't add it using:
route add default gw a.b.c.d
where a.b.c.d is your router address
3. A proxy. Run netscape, go into edit->preferences->advanced->proxies
and add the entry for your
proxy (usually your firewall system). Check one of your windows boxes
for the settings.
Troubleshooting. Most problems are caused by name server settings or
routing. Try entering 'ping www.news.com'
and see if 1. The name is resolved to an IP address. 2. The ping
actually gets out.

Frank Ranner

Another alternative is getpop3, which I've been using for several years. It
is a little easier to configure, perhaps, than fetchmail and has been
reported faster.

When you compile code, one of the options is to include a symbol table
within the code that links to the source code. When you run it through a
debugger, you can see which line is executing at any point in the program,
set watchpoints (points in the program where the debugger will do something
like report the values of specified veriables), breakpoints (this causes the
program to halt at a particular point).
The simplest and most obvious use ofa debugger is to just run a program that
is known to crash, as the last thing the debugger will do is report the line
in the source code that caused the failure (which REALLY helps in tracking
down fatal bugs).
> What is it used for?
D'uh! It's *USED* for debugging programs! What did you think? Insecticide?
> When, why and how to use a Make?
When you have a medium to large program, using numerous source files, make
is used to speed up the compilation process. If you just used gcc, and
#included all the required source files each time, it's not very efficient
and can take AGES for a long program... Especially if you only altered one
line in the code to fix a bug.
With make, each source file is compiled separately and then linked together
to form the final executable. Make keeps tabs on when a file was last
updated, so if you have 4 source files say:
window.c
graphics.c
menus.c
paint.c
Where paint is the main() routine.
Now, using the gcc method, changing one line of window.c would mean you'd
have to compile all the files together to produce the final paint program.
Using make on the other hand, it would detect a change in only window.c, and
would only recompile that file, and then relink the other parts of the
program to form the new execuateble.
> What is it used for?
See above. + lots more.
Make is also capable of generating documentation, installing software, and
many other things. You just have to know how to program it.
> Additionally:
> What is a target?
Another things with make is the ability to have different options included
in the make file.
Commone examples are:
make all (Make all files and executable)
make world (something only deities tend to be able to do)
make docs (don't compile the code, just generate the documentation)
make coffee (This sends a signal to the coffee machine to make coffee)
make install (install the software you've made)
make gpl (strips out all proprietory code from a commercial program and
makes it GPL compliant)
make config/menuconfig/xconfig (make a configuration program and run it)
make clean (remover all files previously generated by make)
All these are targets.
> What is build?
You "build" software. It's another word for the compilation process, and is
also used as a method of versioning by altering the number associated with
each time the program is built.
> What is a makefile?
See above. It's the program that tells make what to do, sets the targets,
etc. No makeifle, no targets, nothing apart from an error message will
happen.
> What is a project file?
Some Developement Environments produce a project file. This can be just a
dump of all the source into one file or a complicated hierarchy of different
versions of the code, depending on the IDE.)

Just hope I've not been duped into doing your homework for you. Get a book
on C programming. Reading books is still a requirement in education, isn't
it?

Not to be trite, but I usually just do an "rm" on the files that make up
the program. Unlike Windows(tm)(R)(junk), there is no "registry" that you
need to worry about. This is if I installed from a tarball.
If the program was installed using RPM, then you
can use the "rpm -e <packagename>" where <packagename> is the name of the
package. I assume that there is an equivalent in Debian, but I don't run
Debian, so I don't know what it might be.
Hope this helps,
John

Depends on how you installed them. For rpm's it is
rpm -e yourapp
Note that yourapp != the same name as the rpm-file. It usually is what
you start the app with
rpm -e bluefish
would remove bluefish from my
box for example. (Not that I want to).

RedHat (and derived systems, such as Mandrake) and I believe Suse use
the RPM system, which provides the 'rpm' command. 'rpm -e' will erase
(uninstall) a package. I think Debian and Corel have their own 'package
management system', which *probably* has a similar functionality.

Install? Have you compiled it or you just try to install it from a
rpm package? I am not sure about AMD K6, but when you compile a kernel
or any program binaries you can specify K6 optimization. In general, optimization
for 486, 586 and K6 will work. Otherwise it will hung right after the
kernel is decompressed into memory.
I have a Cyrix 6x86 for the firewall and I have to take special care to the
optimization when compiling the kernel because it did the same thing you said.

"ddate" converts Gregorian dates to Discordian dates.
Discordianism, if you don't already know, purports to be a
religion which worships Eris, the goddess of chaos. To quote
R.A. Wilson, detractors feel Discordianism is just an elaborate
joke pretending to be a religion, but supports claim it is a true
religion pretending to be an elaborate joke. Decide for
yourself. From the Jargon File:
Discordianism /dis-kor'di-*n-ism/ n.
The veneration of Eris, a.k.a. Discordia; widely popular among
hackers. Discordianism was popularized by Robert Shea and
Robert Anton
Wilson's novel "Illuminatus!" as a sort of self-subverting
Dada-Zen
for Westerners -- it should on no account be taken seriously
but is
far more serious than most jokes. Consider, for example, the
Fifth
Commandment of the Pentabarf, from "Principia Discordia": "A
Discordian is Prohibited of Believing What he Reads."
Discordianism is
usually connected with an elaborate conspiracy theory/joke
involving
millennia-long warfare between the anarcho-surrealist
partisans of
Eris and a malevolent, authoritarian secret society called the
Illuminati. See Religion in Appendix B, Church of the
SubGenius, and
ha ha only serious.
The Church of the SubGenius has a web site with the Principia
Discordia and other information on Discordianism.

Works great. If anyone needs assistance with squid e-mail me at westhope at

After setting up the squid user and group you need to identify rules for
what sites or IP addresses or URL words (etc) pass through the proxy server

Subject: PPP compression revisited
Date: Sun, 16 Jul 2000 08:59:05 -0700
I get the following messages in the RedHat 6.0 'messages' log file when
using 'pppd', (by the way 'pppd' works successfully ... I use it with squid
acting as a caching proxy server):
Can't locate module ppp-compress-21
Can't locate module ppp-compress-26
Can't locate module ppp-compress-24
This item was addressed in a previous post to this thread (Mathew Nimmo,
7/4/00, 8:28am) in which it was suggested that some lines be added to the
'etc/conf.modules', and further, that the user did not share any compression
types with their ISP.
QUESTION #1: Why don't I have an 'etc/conf.modules' file on my standard
RedHat 6.0 installation where pppd is working successfully? (Should I just
create a 'conf.modules'?).
QUESTION #2: How can I tell if I 'share any compression types with my ISP'?
QUESTION #3: How can I ensure that I get some sort (any sort) of compression
over the dial-up phone line to my ISP when using pppd for the connection?
Although the pppd works successfully it oftentimes seems much slower that
when I dial using Windows NT Workstation to my ISP.
