I recently installed netscape 4.76 alongside my existing netscape 3.04,
which broke v3.04. I had exactly the same symptoms as you. V4.76 would run
fine but v3.04 which had run fine for years wouldn't even pop up a window.
It turned out that when I ran netscaoe 4.76 for the first time it copied
a plugin into my $HOME/.netscape/plugins directory. This plugin was causing
v3.04 to barf.
Unfortunately I can't remember what the plugin was called but I can tell
you how to figure it out.
In an xterm run the following command also read the ltrace manpage):
ltrace /path/to/executable/netscape
This will print out all the calls netscape made to libraries. When it
crashes just trace back from the last line to find the last file
netscape opened. It should be a plugin in your .netscape/plugins
directory.
Once you have the plugin name you can delete it like I did and
everything should be fixed.
Hope this helps,
Erik

How to switch between applications ?
Consider, e.g., that I have the following applications running
simultaneously.
(1) gnotepad
(2) Netscape Navigator
(3) gnumeric
etc.
>From the terminal emulator window, what command will list the
applications that are concurrently running, and how can I switch into a
particular application? What command at the command prompt will switch
me into that application?
I already know that if I click on the application window, it'll come
forward. I would like to know if there's a way to do this by typing a
command at the command prompt.

Subject: f77 compiling problem with GNU FEE ver. 0.5.26
Date: Wed, 01 Nov 2000 20:30:05 -0000
Hi, I hope anyone can help me out to compile a fortran package.
The package was successfulluy compiled with GNU Fortran Front End (FFE)
version 0.5.22 and 0.5.24, which are included in the earlier version
(kernel 2.1.x or lower) of Red Hat Linux.
However, I met a problem with compiling the package with GNU Fortran Front
End version 0.5.26, which is included in Red Hat 7.0 (kernel 2.2.16).
In fact, compilation of the package with GNU FFE ver. 0.5.26 created an
excutable file with the following warning messages:
/usr/bin/ld: Warning: size of symbol 'time_' changed from 8 to 14 in
Ltime.o
/usr/bin/ld: Warning: type of symbol 'time_' changed from 1 to 2 in Ltime.o
But when I run the executble file the job is terminated after a few
seconds without any output except the following message:
1199 Segmentation fault (core dumped)
Note that an executible file created by a lower version of fortran
compiler produces an output.
Thank you in advance.
Regards,
Sung Y. Hong

It shouldn't compromise the experience. I have PPC/Linux, Mac OS 9, and
Mac OS X on the same iMac, with no issues. Installation is a little
tricky but if I can do it with almost zero *n*x experience, you can do it
too. A PPC/Linux program called mol (mac-on-linux) will let you boot Mac
OS 9 in a window or virtual console while you are running Linux, if that
helps.

Hardware and distro are hard to pin down. Any current Apple machine will
do fine for the hardware. For distro, pick something you're comfortable
with, since you have some Linux experience. LinuxPPC and Yellow Dog Linux
are both based on RedHat. SuSE and Debian both have PPC distros.

That truly depends. If you are able, find somebody with OS X Beta
installed and play with it for a while to get a feel. You can run many
but not all *n*x apps on Mac OS X, but the feel is very different from
Linux. As mentioned, I have both, and OS X has not made me stop using
Linux.

Nobody. You don't provide enough data. Telling us you "tried to do"
things is zero info. We need to see the command lines and the errors,
nothing more, nothing less. I've done my best to list the working
commands for you above. Now YOU can compare what you have done with
them. But why did _I_ have to do all that work to help you when _you_
could have simply listed the commands and the errors and left it to me
to point at the offending line? You plainly know enough to list some
of the data that is needed, so why not all?

Hi all,
I'm trying to optimize my Linux system as much as possible for running
divx movies. I don't think it's possible with my specs, but I'm an
optimize freak and just want to see how far I get :-)
My specs: toshiba
320 CDT, 32 MB Ram, mobile intel pentium processor with mmx at 233 MHz,
video: Chips & Technologies CT65555 with 2048 kb.
I'm running kernel 2.2.17, xfree 3.3.5, and most recent versions of:
icewm, sdl, smpeg, libaviplay and xtheater. Everything is compiled
manually, except xfree. My questions are:
1. are those the best CFLAGS? -Wall -Wstrict-prototypes -O6 -march=i586
-mcpu=i586 -ffast-math -funroll-loops -fomit-frame-pointer -fforce-mem
-fforce-addr -malign-double -fno-exceptions
2. will it make any difference if i will run xfree 4.x? Should I compile
it with any other cflags than -O3 -march=i586 -mcpu=i586 ?
3. do I need to recompile everything with the best cflags from question 1
again?
4. should i use an other window manager that uses less recources than
icewm? If so, which one?
thanks a lot in advance!

Subject: recompile the 2.4 kernel problem?
Date: Wed, 1 Nov 2000 12:46:44 +0800
I've downloaded the newer 2.4.0-test9 kernel file.
I also updated the software which Changes file pointed out.
But when I use the recompiled 2.4-kernel to boot my system ,I got this
problem as below:
.............
Megaraid : v107 (December 22.1999)
Megaraid : found 0x8086:0x1960: in 03:0b.1
Megaraid : board configured for I2O,ignoring this card .Reconfigure the
card.
Medaraid : in the BIOS for "mass storage" to use it with this driver.
VFS : Cannot open root device "801" or 08:01
Please append a correct "root=" boot option
Kernel panic :VFS:Unable to mount root fs on 08:01
My server is DELL 6450/550 with 4G MEM and 4 CPU,I also have 2 Raid-5(DELL
Powervault 210s) with 1.6 TG storage.
Redhat 6.2 with 2.2.17 kernel can run very well on my server,but it's still
supporting 2G MEM.
Any suggestions or idea are appreciated.
Thanks.

Maintain your own news spool and expire times by running your own
news server. Inn, leafnode, noffle, etc. are all good
candidates. Once you get the server running, connect your news
client to it through the localhost interface (127.0.0.1).

Asking which is the best distribution is rather like asking which
is the best cola. Try a few for yourself and see which one you
prefer. BTW, if you install your /home stuff on a separate
filesystem, this isn't as painful as you might think.

Hi,
I am looking at moving my company from using sendmail under Red Hat 6.2 to
something more secure and that gives me some levels of spam control.
I have been trying out qmail, but am having trouble getting it to deliver
incoming mail - it seems to drop the body of the message and only shows me
the "From" and "To" fields in the header. If someone has qmail working fine
under Red Hat 6.2, could you please give me some tips and at least let me
know what your /var/qmail/rc file looks like?
If any of you have some better ideas for me to give us better security and
spam control, I'd greatly appreciate the help. Thanks!

-O6 does the same as -O42 -- nothing -- -O3 is the limit. Avoid -Os
as it can generate false code (I just ran into that one with the latest
glibc version and -O2 proved to be fine as far as it's possible to tell).
-fomit-frame-pointer and -fforce-mem are being enabled by -O2 already
and -fforce-addr on a CPU with such a limited register set as all Intel
compatibles .. I don't know.
>2. will it make any difference if i will run xfree 4.x? Should I compile

[-]
I'd use -fno-strength-reduce .. it used to generate a./o. trigger bugs
in the compiler even after it was supposed to be fixed and while opinions
differ I've run some benchmarks myself. In general codesize increases
with strength reduction enabled which is bad while speed does not increase
dramatically and some binaries ran slower. Again all for an Intel CPU.
It's a general problem with all optimisations and for some long running
binaries a runtime profiling based optimisation might be a good approach.

Subject: Unable to boot RH6.2 box - Help !!
Date: Wed, 01 Nov 2000 22:43:26 GMT
Hi,
Need some help here... I have RH6.2 running all by itself (no other
OSs) on a box with an AMD-K5 processor and 32Mb RAM. The box has died
on me. Symptons are as follows:
- Normal boot procedure (without boot disk - using LILO)
LILO boot prompt goes on after timeout to start booting (without myself
providing any special parameters). What I see on my screen is something
like this:
LILO boot:
Loading linux.....................
Uncompressing linux...
incomplete literal tree
--System halted
- Booting from boot disk:
I get a "LILO boot" prompt, with a message saying that the machine will
boot from /dev/hda1 in 10 sec if left unattended. I do so, and get the
following screen output:
Loading linux...
Error 0x04
After this I keep getting "LILO boot" prompts that default after 10
secs to trying the same process, getting the same error message every
time.
I have tried accessing in single-user mode issuing a "linux -s", but
results do not differ.
Any help anybody may provide as to how to proceed will be greatly
appreciated. Pointers to specific documentation indicating how to
approach this problem will alse be of great value.
I admit that I have not done a thorough research before posting this,
but the urgency of the problem is forcing me to do both things at the
same time (posting and researching), in parallel. I apologize for that.
Thanks and regards,
Santiago
