Date: Wed, 16 Aug 2000 21:08:25 GMT
I'm setting up a plug-n-play modem on a dual boot P100 w/ plug-n-play BIOS
running RH 6.1. I go into Windose to get IO addresst, IRQ, and serial port
(0x03e8, 11, and COM3/dev/ttyS0 I believe). In /etc/rd.d/rc.serial I have
(to the best of my recollection...I am at work and the machine is at home):
setserial /dev/ttyS2 port 0x03e8 irq 11 spd_vhi
I can successfully use the modem using minicom and ppp. After this, I cat
/proc/interrups and I axpect to see an entry for 11 but do not. I something
going on here? Shouldn't the modem activity generated interrup requests on
IRQ 11 that would show up here?

No. I have found (from experience) that if the first line in the passwd
file is not root's account, no one can log in (at least on Sun and AIX).

Here I'll go perhaps a bit deeper than you hoped for.. but your problem
is addresses close to the end.
I'll skip what happens on the hardware level before the on-disk boot
loader loads in your OS kernel image. So, "first", the kernel image
is loaded from the disk and set to run (with quite a lot of magic..).
Then, when the kernel gets itself straightened out, it will do internal
things, like initialize the compiled-in device drivers and mount the
root filesystem (either compiled-in, or using information given by the
boot loader). An interesting sidetrack is that the kernel image itself
doesn't need to reside on the root fs; it's loaded from the disk using
just disk block addresses.
Then comes the time to start up the first process external to the kernel.
In a normal system that is /sbin/init (which always has process id 1),
due to being started first and due to being unkillable. After this, init
will handle things as configured in /etc/inittab.
/etc/inittab in my RH6.1. contains information of the default runlevel
(here 3). This means that init will run lines si, and l3, and then
goes on to start the virtual console logins. 'si' line will run
/etc/rc.d/rc.sysinit and 'l3' will run "/etc/rc.d/rc 3", which basically
runs all the scripts in /etc/rc3.d. The scripts named 'K*' will be run
with argument 'stop' and the scripts named 'S*' with argument 'start'.
Looking closer, the items in the /etc/rc[0-9].d/ are just symlinks to
real files in /etc/rc.d/init.d/, and things can be changing by adding
or removing these symlinks. So, f.ex. to prevent the hardware detection
from happening when booting up, check your default runlevel from the
/etc/inittab 'initdefault' line, and remove the S???kudzu link from
the relevant /etc/rc[0-9].d/ directory (relevant: number in the
directory path matches your default runlevel).

What version of XF86 are you running and are you using the latest MACH 64
drivers (check out SuSE download under "Xservers)"

Dear linux gurus,
I have a question for you and would appreciate your help.
I have been using Linux for a very long time. I found that the only way
to crash a linux machine is to load many many applications so that all
the RAMs+Swap disc are full. Then Linux box would sit there helplessly.
Recently I experienced this with Acrobat 4.05 and attempted to read a
box. It took away all memory and swap file system and the machine just
refuse to respond.
Any way to fix this? Is there any kernel parameters you can tweak with
to fix this?
Thanks

Subject: SuSE 6.4 YaST2 Install Video Problem
Date: Wed, 16 Aug 2000 17:15:43 -0600
After the first installation reboot, the graphical SuSE 6.4 YaST2 comes up
in a video mode that does not allow access to the entire screen or required
menu selections.
I've been trying to do an install of SuSE 6.4 on a dual-processor, Windows
NT PC. I used Disk Administrator to made 6GB of free space at the end of
the drive and I follow the HOWTO to use NT Boot Manager (which I have
successfully done on another machine). I boot using CD 1 and make the
installation selections just fine using the graphical SuSE YaST2 setup tool.
After the kernal is installed, the installation requires a reboot. When I
reboot the system, regardless of whether I have put LILO on the Linux boot
partition (and continue the install using the original boot disk to boot the
installed system) or on a boot floppy, the YaST2 graphical interface (that
worked just fine for the beginning of the installation) comes up in a mode
where I can only see the top left 20% or so of the screen. The mouse works
fine within the confines of the physical screen, but I cannot move out of
the top left corner of the virtual screen. Moving the mouse to the edge of
the screen doesn't scroll. Ctrl-Alt-+/- or Ctrl-Shift-+/- and other
combinations that change video resolution in a fully installed system do not
work. The "Insert CD 2, 3, etc." messages come up in the middle of the
physical screen, but when the installation gets to the screen to select and
test the video mode, the buttons to select and test cannot be seen to select
and test.
Suggestions, please.

Greg,
although the other posts explaining the startup procedure and the
symbolic links correctly, you should try to avoid removing or renaming
the links manually.
There is a system utility called chkconfig which does the job for you
and allows you to easily turn scripts on or off, even depending on the
run level.
In your case you would use the command
chkconfig kudzu off
The command
chkconfig --list
will show you which scripts are started in which run level.
This way you can create your own scripts in /etc/rc.d/init.d. Have a
look how these scripts are built, it's quite straight forward.

Subject: VPN Oddities?? Please Help
Date: Thu, 17 Aug 2000 09:51:46 +1000
Hi,
I've got two networks connected in a VPN using FreeSwan IPSec. One of the
networks which I will call .11 (as in 192.168.11.0) has a edge machine A and
the other .1 (as in 192.168.11.0) which has an edge machine B.
Firstly, I can't ping from A into the .11 network and from B I can't ping
into .1 - Is this a limitation of IPSec? But from inside .11 I can easily
ping machines inside the .1 network.
The A machine also runs Squid and DNS which are causing problems...If people
on the .11 network need to access the internet through squid, then all is
fine...but if they want to access a site within the VPN in the .1
network...then the site becomes unreachable...unless squid is bypassed.
There is also difficulties in loading zone files across the VPN.
With IPSec, is it necessary to run edge machines that are dedicated to
running the VPN?
The machines are PIIIs and run RH6.1
Any help that can be offered would be greatly appreciated!
Thanks in advance.

I haven't seen your previous messages [1], but if you're using a display
manager like xdm, gdm, or wdm (you'll know because you get a graphical
login screen instead of having to use startx) then you'll have to put
'exec gnome-session' at the end of your .xsession rather than your
.xinitrc.
In situations where I might want to use either of xdm or startx, I often
make $HOME/.xinitrc a symbolic link to .xsession, as in my experience
it's rare that they need to be different.
[1] Yet ... c.o.l.s is quite a big newsgroup to try to keep up with ;))
