Such processes are called zombies. On our old Suns, we had a command
which would kill zombies, but it usually didn't work. I haven't seen
zombies on Linux systems very often. Probably the simplest solution
is to reboot.

I am new to the Linux world. When I assembled my PC, I set a 2Gig
partition
aside for Linux.
I can buy SuSE 6.1 for $30.00. I missed the thread on the same topic by
Dave Brown because
those articles had expired. RH6.0 costs about 70 bucks.
With SuSE, I'll also get CDs for StarOffice5.0.
Is it ok to use install SuSE ? or Should I go RH6.0 way ?
Thanks for any suggestions.

Subject: backup with tar
Date: Mon, 14 Jun 1999 15:17:35 GMT
I used to backup my system-files/homedirs ... with tar to another
machine. a few days ago I had a diskfailure and had to reinstall my linux
and save back the tar-files.
I ran into two major problems:
* tar didnt restore the file-permissions
* I ran into a ^M-problem in every configuration-file.
(a problem with the LF/CR or such thing. All tools said, that there is an
error in its configuration-file and when I openend it and replaced all
newlines with 'new' newlines all was running fine)
my question :
is this a common thing or is this a special problem of my way of taring:
for tar I use:
tar czvhf tarfile ...
for untar I used winzip (which can handle .tar.gz-files) on a nt-machine
and burned the whole thing on cd, cause I didnt had enough space on the
remaining harddisk to put the whole tar-file there.

I had to install redhat5.2 again and didnt install any x-stuff cause I
dont need to run a x-server on a pure text-terminal.
but I still want to ssh-forward my x-sessions to another machine (where a
x-server is installed). but now I cant even run x-clients (netscape etc.)
and ssh tells me that it cant support x11-forward.
so what stuff do I have to install to run x-clients without installing
all the stuff I need for running a x-server. (my harddisk is not as big
as should be ...)

Howdy,
It can all be done using lilo! I'm sending you a listing of my lilo.conf and
fdisk from the boot drive. The trick is that the Solaris partition is seen
as Linux swap and it MUST be the active boot partition for the drive
otherwise it's a no-go!
I have DOS, <giggle> W98, NT4.0 Server SP5, Linux 6.0, and Solaris 7
cooperating on the same system. Not at the same time mind you but still
cooperating. Remember to install DOS or W98 first, since 98 or 95 will wipe
out the MBR for Linux later. Then install NT, Linux and after the install
of linux create another swap partition using fdisk and install Solaris on
that.
Why did I do this ... to see if it could be done!!!! :) So far up and
runnign for the part 18 months using all of them!
HTH
Cheers,
CJ

One machine I know with which had this problem had a hard disc subject
to hardware failure. It now runs 24/7 without any problems for
months---and as a web proxy and print server failure would be obvious
to lots of people.

Puh-lease... If someone can get into your system, what use is it
to have your password encrypted? Besides, they could intercept the
password being sent to telnet. You should use ssh, instead, because
it encrypts the password being sent; but your server needs to have
it (they should.....) It's even simpler than the following telnet
script, because you only need to enter the password.
Assuming you have expect/tcl, just put the following script into a
file which only you have permission to read/execute:
-=-=-=- cut here -=-=-=-=-=-=-=-=-=-=-=-=-=-=-
#/usr/local/bin/expect -f
#
#(the above path may be different, so "which expect")
#change these
set USERNAME username
set PASSWORD password
set HOST your.host.edu
spawn telnet $HOST
#may have to change these, depending on what your server emits
expect ogin:
exp_send "$USERNAME\r"
expect assword:
exp_send "$PASSWORD\r"
interact
exit
-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
If you're paranoid someone will see your password, you can modify
that to get user password (but then why automate login..?).
'man expect', and it tells you exactly how to do that.

Actually, g77 is the real compiler, and fort77/f2c are the fortran-to-c
script tools. In general, fort77 has more goodies, but can be less fun
to debug. As an example, the -r8 option is available on f2c (i.e.
fort77) but not g77.
I have heard that fort77 can generate faster code than g77 but I haven't
seen this with my own codes. I use g77 for most stuff.
There is a "free-ish" f90 compiler (converts f90 to f77) available from
www.psrv.com -- which uses g77 to compile stuff. It has restrictions on
use, though, so read the agreement carefully.

No, not as such, but early on there was a simple OS lock that could be
tested. If MSDOS was doing something that could not be interrupted, it
would set the "InDOS" flag.
Also, the Multiplex interrupt, in 2F, used for the old print spool
command "multitasked" a bit. The multiplex interrupt became a way for
TSR programs to get system time. When activated, they would check the
InDOS flag, if it wasn't set, they could make DOS calls. Cool.
It should be noted, once more in the category of Windows is still DOS,
the InDOS flag and the int 2F multiplex interrupt are still alive and
well doing what they have always done.
BTW most of the original UNIX implementations were not reentrant.
However, that did not mean they could not multitask. It just means that
a call into an OS service could switch you away. Win16 was also
non-reentrant, calls to getMessage and PeekMessage would switch you away
too, and they were multitasked (cooperatively, but did multitask)
Where is this going? Well, the virtual machine multitasking (DOS boxes
and the system VM) are handled by a very DOS like creature named the
Virtual Machine Manager. VMM provides a DPMI environment in which
Windows (3.0,3.1,95,98) resides. DPMI stands for DOS Protected Mode
Interface.
So, in a way, Microsoft did add the multitasking stuff to DOS. They just
hide it very well. In Windows 95 and 98, however, preemptive
multitasking and threading amongst 32 bit Windows apps is managed by
Windows, while multitasking virtual machines is done by the VMM.

When you download something, it usually comes in one of two forms,
a tar file (or compressed tar file), or an rpm file. (rpm is something
developed by redhat but open sourced and used by other distributions.
Other people can tell you more about than I can.) If you get a tar file,
it should end with the suffix '.tar' (i.e. xv-3.10.tar) where tar stands
for 'tape archive'. There is a program called tar that can list the
contents, create a tar file or extract files (do a 'man tar' to learn about
it). More often, though the suffix will be '.tar.gz' or '.tgz' this
means besides being archived it was compressed with gzip (do a 'man gzip').
You can extract files with something like 'tar xvf xv-3.10.tar' or if
compressed 'tar xvfz xv-3.10.tar.gz'), but it's usually a good idea to
see what's inside first with 'tar tvfz xv-3.10.tar.gz'), see if it's
going to create a directory tree with everything under some directory
name or scatter files around in the current directory. Until you get
used to doing it, I'd take the precaution of doing something like:
'mkdir xperi; cd xperi; tar xvfz abc.tar.gz'. With rpm it's much more
automated, I think 'rpm -i xyz.rpm' is all you need, but see if you
even have rpm on your system and do a 'man rpm' if you do.
Once you've extracted the files, they may be binary but more
typically they are source files that need to be compiled. Usually there
are some help files with names like README and INSTALL that you should
read. Very often these days, there is a file called configure, and
often all you have to do is run the following sequence:
../configure
make
make install
to get the stuff installed. There's a lot more to it, options one can
give to the configure command for instance, but hopefully
that will get you started. Understand that these packages are often
done by people who have created something for themselves and are just
being nice in sharing them with others, they are under no obligation
to follow the conventions implied in what I've just described, sometimes
they are actually more comfortable in other operating systems and just
port to linux and don't know all the details of how to create a configure
script, they are, as I said, just being nice, so you'll get a lot of
variation in what you download, but there is usually some kind of README
to help you along, inform you of bugs, whatever.

This is a FAQ (Frequently Asked Question)... please try to read the FAQ lists
first before posting. Having said that....
The most common reason that there is a large delay between connecting and the
login prompt is that your Linux machine is attempting to do a reverse-name
lookup on the Win95 machine's IP address, and you either:
a) Don't have a DNS configured for your Linux machine (unlikely)
b) Your Linux box is unable to contact the DNS (possible if, for example,
your Linux machine and Win95 are a home network, and you haven't dialled up to
your ISP)
Usually what fixes this problem is if you change your /etc/hosts file so that
it lists your Win95 machine in it. Example:
# Sample hosts file
127.0.0.1 localhost
192.168.0.1 linuxbox.somewhere.com linuxbox
192.168.0.2 win95box.somewhere.com win95box

It sounds like sendmail is getting stuck trying to do DNS resolution.
You'll likely need to go through and disable DNS lookups and perhaps
define a smarthost which you can punt your mail to. Take a look at
