Subject: nfs home dir's question
Date: Thu, 24 May 2001 13:21:08 -0600
I need a pointer on an nfs problem. Currently my systems are mounting
the users home directories from my nfs server. When the nfs server is
down they default back to the root on their local machine. I would like
to create a way for them to fail to a directory either on their local
machine or another server. Currently we use NIS for authentication,
I'm not sure if there is a map that would help with this or if there is
something in automount/nfs that would accomplish what I need to do.
Suggestions would be appreciated.
Robert.

It might be good to know what this system is all about, what its used
for. What was running, etc. There really isn't much for trouble
shooting this type of request. We need specifics.

Well I had that same problem and I changed my screen from 640 x 480 to 800
x 600 and 90% of the problems were solved, it seems that the problem is not
with the actual dispaly but the window which shows up with the size of 0 x
0, like the gnibllets game.

Martin;
To answer your question. When you login in your system forks your shell
and that becomes you running pid. If you run plain old startx with our
without modification there are two things that can happen. When xinit
reads the .xinitrc in your home dir it launches your specified window
manager. IF the .xinitrc specifies that xinit should "exec" the window
manager (which you should do for security sake if you have to be away
from your machine) it will replace the login shell with the current
shell used by the window manager when it fork IE the window manager
essentially takes over the login.
To see if this happens go back to the login prompt on that terminal and
hit enter a couple times if it comes back then you lost nothing. If it
doesn't then you have "exec <window manager>" in either .xinitrc or
.xsession and that is whats killing your console. If you don't have the
exec in the I would put it in there or someone will hi-jack your console
it's just a matter of when.

I had a similar problem with an adaptec card but tried an advansys card
instead and the same thing happened. I put it down to incompatabilities
within the so called SCSI standard, as soon as I removed my old SCSI 1
drives the problem went away. I'm pretty sure termination wasn't the problem
as these drives were in the middle of the chain and unterminated (I removed
the resistor packs to make sure).
I now use both SCSI controllers, one with my old drives and the other with
my newer CD writer and hard disks. This works flawlessly.
Hope this helps.

How about putting a cartridge slot in a PC, and set it up as the first

Try using a different irq (2,5,9 etc.)

/.login:

if [ "$ID" != "root" ]; then
cd /someotherlocation/$ID
. ./.profile
echo "Using temporary home: `pwd`."

Something like that.

Although tar is used in unix like zip is used in other systems, a
tarfile is not compressed. However, after it is created, the whole
file may be compressed with gzip.
Tar was originally used for tape backups, so the default file is a
tape device. To override this, use the -f option.
The answer above will work if the files have been archived using only
the names a and b. If there is a pathname stored with the name, you
will need to mention that somehow in your tar command.
Emacs has a special mode for dealing with tarfiles. You can use it to
list contents and copy individual files wherever you want them.

Subject: kernel failure error question, and mount question
Date: Thu, 24 May 2001 17:04:26 -0700
i recently compiled a new kernel for my rh7.1 linux box (win98se is on
it too). i compiled 2.4.4 for linux so i could have a newer kernel and
be able to use my winmodem. i could have jsut recompilied my origional
kernel but i chose not to. i needed to enable "set version info. for all
modules", and i was told it was in the loadable module support catagoy
in xconfig, but what do i change, when i compiled my kernel all 3
choices were set to yes. is that what i was supposed to do?
also, my 2.4.4 kernel has a coupple of problems with my new kernel. when
its starting up linux i get the following "failed" errors....
tuning on process accounting accton...function not implemented.
bring up device eth0: delay in eth0 initalization.
also, when i try to mount one of my fat32 partitions in linux with the
following command:
mount -t vfat /dev/had5 /mnt/my_files
i get the following error....
mount: fs type not supported by kernel
and when i shut down i get two failed errors but i could only bearly
read one of them--they went by tooo fast, the 1st one was something
about aumix.
im assuming these errors have to do with misconfiguration my my new
kernel.
how do i fix these problem? recompile--with what changes?
lastly, i know that in xconfig i can just click help to see what a
certin option is/does, but is their a web page/site that has the
same/their version of the info in the help section so i can print it out
as a referentce. i cannot print underl inux yet, i havent gotten to
printtool yet ;-) ----- and i dont think i can print the dialog box that
come up for help anyways.
in case it help, when i use my origional kernel (2.4.2) i have no erros
at startup/shutdown or with the mount command.
thank you,

The first thing that you need to do is make sure that the Freesco router is
setup to perform IP forwarding for you. There should be an option within the
system to enable it. Additionally, you may also have to specify a ipchains
statement (although I am not sure whether the Freesco) can do all of this for
you automatically.
Your machine that you wish to connect should be connected to the router either
via a cross-over cable if it is connected directly to the ethernet port or via
a hub if a cross-over cable isn't available. The machine should be configured
to use the network card for the local LAN in the router as its gateway
address. The subnet mask and DNS setup should also be setup appropriately.

If you can tell us how much you have done with regards to setting up the
router to forward traffic for you and whether you are doing NAT or whether you
are passing IP addresses straight through, that would be very helpful.
See ya

Subject: Minimum System Requirement For This Setup

Hi ,
I want to run Linux (any distro , preferably Redhat) as a dedicated CVS box
,
connectable from a Windoze box (assuming max. 1 connection at any time). I
do
not want X or any other software running.
1)Do I need Samba installed ?
2)Can anyone advise on the minimum realistic hardware requirement in terms
of
RAM , Harddisk space and CPU for this simple Linux setup ?
I have an old Intel 386DX 4MB RAM with 80MB of hard disk and thinking of
making use of it. Would it be enough (ignoring the size of the source code)
?
Thanks.
