Subject: VM: killing process - box freezes
Hi,
Thank you for the hint about memory usage. I had now a look=20
at it and this time I was even looking when it happened. Just=20
shortly before I did a top and got:
Mem: 130660K av 127732K used 2264K free
Swap: 257032K av 500K used 256532K free
Just a second before it froze swap usage increased to 1120K.
I am confused now. Swap wasn't hardly touched.
Also, this time there was nothing in the /var/log/messages file.
Weird, any ideas?
Thanx
Doro

Subject: file is not found - but I know it exists!
Date: Sat, 18 Nov 2000 11:57:27 GMT
Reply-To: [EMAIL PROTECTED]
I am worried because it seems that bash cannot find a file I know is
there. The setting is: I'm trying to install the wonderfull "Stata"
statistics programme on my laptop. But ...
The "installation script" extracts some files into the directory
"/usr/local/stata", among them the executable "stinit" which is used
to initialize the license and such. But while I can see the file with
ls, and filename completion works ok, bash complains that it cannot
find such a file or directory when I try to execute the file. The
"find" command recognizes the file as an executable.
See the following transcript:
#: pwd
/usr/local/stata
#: whoami
root
#: ls -l stinit
-rwxr-x--x 1 101 users 10040 Jan 11 1999 stinit
#: ./stinit
bash: ./stinit: No such file or directory
#: /usr/local/stata/stinit
bash: /usr/local/stata/stinit: No such file or directory
#: file /usr/local/stata/stinit
/usr/local/stata/stinit: ELF 32-bit LSB executable, Intel 80386,
version 1, dynamically linked (uses shared libs), stripped
I do not understand what is wrong here - my linux installation appears
in all other respects to be very stable (SuSE 7.0), but clearly something is
wrong.
Would apreciate a tip from someone more experienced than me.
Best regards,
Erik.

There must be a better way of killing something that won't go away?

Just use the builtin command line editing facility. Select the

typing <ENTER> to invoke a command.

Have you tried anything as simple as _reading_ the man page for
kill???
The default signal sent to a process with the command you are
giving is SIGTERM, which typically will do nothing if the
process is catching it. You can also try "kill -1 <pid>", which
also has the same problem that using -15 (SIGTERM) has.
When those have been tried and have failed, use "kill -9 <pid>"
because a SIGKILL cannot be caught by the process.

I assume you've used "kill -9 pid"?

So I wasn't *too* far off then...
Just a little too lax in the old permissions.

Nope, because apart from the core system that takes up about 10 Megs,
(although a VERY cutdown rescue linux can reside on a 1.44 floppy)
everything, including X is optional. You could go back into YaST and remove
a LOT more packages than that.
I myself don't use KDE or GNOME, so have only installed the base libraries.
I use one window manager (Why would I need more than one).
Some of the SuSE dependencies are a little bogus as well, so you could
remove for example SaX, fvwm and XF86Setup. X does NOT need these, even
though the suse rpms have been built in such a way as to flag them as
dependencies.
This is my disk usage.
Filesystem Size Used Avail Capacity Mounted on
/dev/hda3 968M 873M 44M 95% /
/dev/hda1 94M 61M 28M 69% /usr/bin
/dev/hda6 144M 135M 1.7M 99% /misc
/dev/hda5 292M 235M 41M 85% /opt
/dev/hdb1 161M 103M 49M 68% /var/spool
I have big stuff like wordperfect, netscape and alpha-centauri demo on /opt,
so that can be discounted from my total for a good working system. You can
discount /misc, it's just a place I dump backups and stuff.
So my base system clocks in at less than one Gig...
Learn what the packages you installed do, and how they are used in the
system. You could remove another few hundred megs worth without affecting
system performance.
Now for the bloatware definition.
No. Bloatware it a monolythic application of a MASSIVE size, usually written
by one team and so tends to have a lot of flaws and bugs. StarOffice is one
good example.
With windows, 250 is for the BASE system. 250 Megs on Linux is enough to
install a working system with enough applications to do usefull work.

You didn't. :)
Apache: Suse installs this by default to serve up its help database.
The help database and apache were another set of packages I removed
from my system. That saved quite a few megs of disk space.
Telnetd/ftpd/fingerd etc can all be deactivated by editing the
/etc/inetd.conf file and commenting out the relevant lines.
Out of the box, no operating system is fully secure. The user should always
take responsibility for fine tuning.

No, it's just a default setup.
:)
Bloatware, as I said earlier is not an array of small tools written by
different people, but a large, bloated, festering blob of code.

Simple. Use a cross compiler... A compiler is not processor dependent. You
don't NEED to compile code just for the processor the compiler is running
on. Think of a compiler as a translator. It doesn't need to translate into
i386. It can just as easily translate into MIPS, Sparc or ALPHA.

Look at the Linux Documentation Project.
There's one in particular called the Linux Developers Guide (or something
like that).

Probably GCC, yes. GCC is not JUST a compiler for linux. Linux has been
around for about 10 years. Unix, on the other hand, has been around for
faaar longer (closer to 40 years). The linux kernel could just as easily
have been cross compiled on a unix system and transferred to a PC.
I *THINK* GCC is older than linux. If not, CC might have been used.
