You're immature and lack developement. If posting childish babble is

Hello Eric,
The first step would be to get an MTA going. The popular ones seem to be
sendmail, postfix, qmail and exim. (postfix is my choice). The
documentation for MTA should be a good tutorial in setting up a mail
system by itself. And iirc the sites for these programs have links to
some useful documentation.

There's a 2.4 snapshot (test6) in the /preview directory of RH 7.0,
and all of the packages on the cd are high enough versions to work
with 2.4. If you plan on migrating a RH 6.2 system to a new kernel
series, you should plan on updating numerous packages. See the kernel
release notes and the README in the preview directory for the gory
details.
The short answer, however, is that a fresh install of RH 7.0 followed
by an immediate install of the new kernel patches is your easiest
route. Once 2.4 is official, you'll probably want to compile it
yourself again, but that's relatively painless.

Hi Peter, I try the nightly builds once a week. The one from this Friday
seems quite stable, and you're right - it's fast at rendering and also in
rendering cached pages.

There are several different things to which the term "alias" is
applied. There can be email aliases for example, where email
addressed to a given name is delivered to a userid with another
name.
What you are describing is an alias for a given IP address, whereby
it has more than one host name. That kind of alias can be made by
making an entry in the /etc/hosts file, and making sure that your
system will look in that file before going to a name server. Your
/etc/host.conf file should have:
order hosts bind
multi on
in it. The first line is important, and the words must be in that
sequence. Then in /etc/hosts you need an entry that reads something
like this
192.168.0.2 somebox.somehost.com somebox
Where the "192.168.0.2" is replaced with the actual IP address
of the host you are naming. (There can be more than just two
names, too.)
Another alias you might consider is the command alias for bash.
That is the kind that goes into ~/.bashrc and can invoke a long
command line with a single short command. For example, you might
have this in your ~/.bashrc file
alias ts='telnet somebox.somehost.com'
And from that time on you can just enter "ts" instead of the
entire command line. If you do that often, "ts" is a good
name. Try to use one letter alias for things you do *very*
often, two letter commands for things done often, three letters
for common commands, and four or more for things that you'll
never remember the name from one time to the next unless it
says exactly what it is.

hey all,
i have a dual cpu sun machine with 256mb ram running rh 6.2. if i
configure the system so that not much of anything at all is running,
coming off a clean boot, top reports 209mb in use! uptime reports .16 .12
.17 when only root is logged in and just sitting at a prompt.
i've got a pair of 100mhz cpus in there, 256mb ram, and barely anything
running on the system, yet it behaves as though i'm doing some serious
work.
is there anything i can do about this? is the memory in use being
incorrectly reported? starting x and using things like gtop and xosview
show the same thing... massive resources in use with not much happening on
the system at all.
conversly, i have a p75 with 48mb that has nearly 50% of resources
available coming off a clean boot, and that with sendmail, apache, etc
started. ( rh7.0 )
i'm about to scrap the whole thing and go back to solaris, which would
truly suck because i *know* linux should be orders of magnitude faster on
this older/weaker hardware...
any ideas?
thanks!

Hi ,
You should try imho " LINUX in a Nutshell " by " O`Reilly " and for the
Distro i would recommend SuSe 7.0 ( for ease of use ) or Slackware ( for the
More Advanced user ).
No doubt from this i`ll get some stick on the matter but these are my own
preferences.

I had the same problem, and I got myself to
a command prompt at that point, logged in as root, and
issued shutdown -h now
which finished the job. I just put 7.2 on here last night
and can't tell you quite how I got to the prompt - maybe I
did alt-F2 to start a terminal. Seems like an oddly
basic way to halt a system that's otherwise trying to be
very graphical.
Otherwise I found 7.2 to be a very nice fresh install --
I wasn't doing an upgrade though. I have found no
shortcomings so far except for some documentation which
was not finished in time for the release.

Yes. And usually all will work fine on a standalone desktop box.
And Qt itself shouldn't be the problem (no regularly used binaries in
it apart from moc), but - when compiling other packages oneself which
do link Qt.
BTW, with most packages one can add the 'run time path' compiler flag
by setting LDFLAGS. But unfortunately some Makefiles override these
'automatic' Makefile-variables without care. And - the proper
environment variable even varies sometimes (CFLAGS e.g.).
I know an environment (Suns most of the time), which always had
LD_LIBRARY_PATH set to Sun's X11 libraries. MIT-X11 apps were
compiled without care and now one gets conflicts all the time about
particular libXt version numbers or alike.

All distros that come with a paper manual should include a chapter on
partitioning the hard drive, your options in doing so, and advice on the
best way to do it. Generally, you make a small partition on the first
drive that's within the 1024-cylinder (8G) limit and call that /boot .
If you're not using the last partition on your old 8G drive for much
atm, put all of its stuff elsewhere, delete that last partition, and
make a 20M Linux partition + a 1.9G FAT partition in the space that 2G
partition used to occupy.
People have had massive discussions on how large the Linux partitions
need to be. Basically, you want one swap partition of about 128M.
Everything else is up in the air and will depend on what you want to do
with your machine. Often, people will create one big / partition to
hold everything, but there are some good reasons for separating this big
partition into / , /var, /home, /usr, and /usr/local/ . / should be as
small as you can make it, /var should be a couple hundred M, /usr should
take up a lot of space, and /home should too.
You can fit a lot of stuff into 2G of space, but if you want to store a
lot of data and/or have a lot of Linux programs hanging around, you'll
want at least 4G. Linux can read and write to FAT16 and FAT32
partitions without problems, but Windoze can't read ext2 filesystems at
all. There's a program called "explore2fs" which lets you read and
write ext2 partitions from 9x/NT, but 'Doze programs can't work
with files on ext2--you must use explore2fs to copy things over to a FAT
partition.
See http://linuxdoc.org/HOWTO/ for the Partitioning HOWTO, and check
http://linuxnewbie.org/ for possible answers to your questions. HTH,
good luck and enjoy the penguin....

A shared library generally has a filename ending in .so , and consists
of code which is dynamically added to an executable at runtime. When
you compile "int main(void){printf("hello world"); return 0;}" with
shared libraries, the executable looks kind of like so:
[initilization code]
[execute the function printf with arg "hello world"; it should be mapped
into memory at 0xBLAHBLAH, if it isn't, it's in /lib/libc.so.6 ]
A static library generally has a filename that ends with .a , and if you
link a program with a static library, code from the static library is
added to the executable directly. The program would then look like so:
[initialization code]
[execute the function printf with arg "hello
world"; machine code for the printf function follows immediately below.]
[a bunch of code for printf()]
When you specify "-lblah" to the compiler, it first looks for
"libblah.so" and if it can't find that, looks for "libblah.a" and uses
that--*unless* you tell the compiler "--use-static", when it only looks
for libblah.a . Dynamic linking is the default, since it reduces the
size of the executable greatly and is often more memory-efficient.
Kernel modules are special in that they're linked to the kernel and they
run in kernel space. The specifics of the linking and dynamic loading
mechanism that kernel modules use are beyond me atm. The documentation
for "insmod" may answer some of your questions.

Sir:
You posted a 3222-line message which contained a large amount of crud to
5 newsgroups. Posting very long messages (anything over 300 lines that
isn't a FAQ list, usually) is considered rude by everyone, especially
people with slow dialup connects, people who pay for every incoming
byte, and people who run news servers. Your 170K post has propagated
across Usenet, wasting (several hundred*170K) of disk and bandwidth.
Someone has to pay for those resources, and it sure as heck wasn't you.
I not-so-humbly suggest that *YOU* need guidance and direction on the
basics of nettiquette.
