Subject: Kernel "ro" Parameter
|
|
Date: 1 Sep 1994 17:28:42 GMT
|
|
|
|
I am in the process of configuring a Linux box to run in a
|
|
networked environment. A few days ago I came across an error
|
|
message during boot and started investigating it. The details
|
|
are listed below:
|
|
|
|
kernel: 1.1.12
|
|
lilo: 0.14
|
|
SysVinit: 2.4
|
|
|
|
Problem:
|
|
|
|
Use lilo to setup boot partition, mounting root as "ro" (lilo
|
|
boots from partition boot sector, not MBR of disk). When
|
|
booting, init (SysVinit) reports error that "ro" is an invalid option.
|
|
The "ro" flag should not be passed to init, it should be
|
|
stripped from the command line by the kernel (or lilo?).
|
|
|
|
Fix:
|
|
|
|
Linux source, subdirectory init, file main.c, function
|
|
parse_options:
|
|
|
|
while ((line = next) != NULL) {
|
|
NEW--> int PassToInit = 1;
|
|
...
|
|
}
|
|
} else if (!strcmp(line,"ro")) {
|
|
root_mountflags |= MS_RDONLY;
|
|
NEW--> PassToInit = 0;
|
|
} else if (!strcmp(line,"rw")) {
|
|
root_mountflags &= ~MS_RDONLY;
|
|
NEW--> PassToInit = 0;
|
|
} else if (!strcmp(line,"debug"))
|
|
...
|
|
NEW--> if (PassToInit)
|
|
/*
|
|
* Then check if it's an environment variable or
|
|
* an option.
|
|
*/
|
|
|
|
If this problem has already been fixed, please let me know where I can
|
|
get the "official" patch.
|
|
|
|
Thanks!

Can anyone suggests a reason why my ppp dies? I upgraded to the lates 082994 driver because the one in the
|
|
kernel (1.1.49) didn't work either. I've used debug to look at what happens -- I get a connection--and it sends
|
|
a few requests and gets a few replies for things like mtu--then the linux end sends some requests for ids? maybe,--
|
|
lcp requests and then pppd dies with a sighup --- is the kernel killing pppd?--I've also noticed my serial communications
|
|
under linux don't seem to be too good--zmodem and term give lots of errors--I'm using a 14.4 modem and term just
|
|
told me I was getting 544 CPS can anyone help me?

|
|
Date: Sun, 4 Sep 1994 18:14:14
|
|
|
|
Hello Linux hackers -
|
|
I know this isn't a Linux development question, but it _is_ a Linux specific
|
|
programming question, as svgalib is linux specific -
|
|
Anyway - I've been fooling around with Jan Kybic's GhostScript front end
|
|
BMV, mainly cleaning up the user interface a bit (personal prefs). However,
|
|
this is the only svgalib program I have that won't allow me to switch VCs.
|
|
I've checked out the sources for zgv, a graphics viewing prog. and it doen't
|
|
seem to be doing anything special in order to support VC switching, and bmv
|
|
doesn't seem to be doing anything special that would _disable_ switching, so...
|
|
BTW, this is with svgalib 1.12 (shared libvga 1.1.8)
|
|
Any help out there?
|
|
Thanks,

Subject: DOSEMU 0.53 notes
|
|
Date: 4 Sep 1994 23:05:50 GMT
|
|
|
|
i've started playing around with DOSEMU .53 and i am VERY impressed.
|
|
the idea of being able to have a real word processor (WP 6.0 DOS) and not have to
|
|
be in DOS/Windows is absolutely great!!!
|
|
|
|
just a couple of notes. things i've noticed and problems i've had
|
|
|
|
mouse doesn't seem to work to well--do i need to run the DOS driver? when i do
|
|
i'm told its already loaded.
|
|
|
|
is there support for the ATI mach32 chip? i can only get 640x480 16 colors in
|
|
graphics mode for WP--though the fact i can get graphics mode at all is great! the
|
|
screen goes screwy if i try 256 colors. and if i try a different mode, WP tells me
|
|
it won't work with my hardware config (it does work in native DOS).
|
|
|
|
also, what do i need to do to get color in text mode--i got it once and i haven't a
|
|
clue what i did, but i never saw it again.
|
|
|
|
i do get color text in an xterm though. that has LOTS of potential. it does seem
|
|
a lot slower though. also delete and bs wouldn't work, but that might have been
|
|
my termcaps not set up write in the dosemu.config or something like that.
|
|
|
|
interesting--MS-UNDELETE won't work, it says i'm on a network drive and must use
|
|
delete sentry--that's the one where it just copies deleted files to a hidden dir.
|
|
|
|
lastly, can someone give me some information on good and SAFE ways to redirect boot to
|
|
my DOS partition. i also use double-space, so i'd be interested in knowing how to
|
|
gain access to that--the HOWTO is not completely clear and i'd really prefer not to
|
|
thrash my hard drive, it's young and i want to break it in slowly.
|
|
|
|
all in all, great stuff!!

Subject: missing headers

Date: Sun, 4 Sep 1994 23:40:42 GMT

|
|
I need some help from someone who has a copy of W.R. Stevens'
|
|
"Advanced Programming in the Unix Environemnt" (Addison Wesley
|
|
1992, ISBN 0-201-56317-7) - a great book, btw.
|
|
|
|
This book contains tons of exercises, and you can get the source
|
|
from ftp.uu.net (look for published/books/stevens*).
|
|
|
|
Anyway, many of the example sources include a couple of headers
|
|
that aren't in my Linux distribution (Slackware 2.0). They
|
|
are: stddef.h & stdarg.h. There are also other headers Stevens
|
|
says are common, but I don't have: cpio.h, float.h, langinfo.h,
|
|
& search.h.
|
|
|
|
My question is, was leaving these out a mistake? If not, what
|
|
are the substitues? If no substitutes, then why does Voelkerding
|
|
think we don't need them?
|

Oops!
|
|
Sorry to follow up my own post, but of course, five minutes after posting
|
|
I solved the problem, after perusing the svgalib sources a little more
|
|
closely.
|
|
It turns out the bmv spawns a background process to monitor the keyboard
|
|
while the parent is doing the display , and the two processes use SIGUSR1
|
|
to communicate - svgalib uses SIGUSR1 and SIGUSR2 to indicate VC aquire and
|
|
release! So, bmv's sighandler on SIGUSR1 was getting in the way. I removed
|
|
the background reading process ( I'm not sure why it was there anyway) and
|
|
voila! VC switching!

We use the Mach microkernel as a base and implement Linux on top of it.

Look in /usr/src for blkdev.h.. found it? If so, start over

and use "patch -p0" instead of just "patch".

Yeah, I get this too. I always assumed it was a hardware problem, since
|
|
I don't run the machine under DOS, but recently my mother has been using

|
the machine under DOS and it doesn't seem to happen there. It was about
|
|
45mins fast after about 5 hours use the other night too - gave me a real
|
|
fright. The problem seems to have got worse a few kernels ago.
|
|
I manually fix the clock (and yes, I do write it back to the CMOS clock
|
|
as well) whenever I boot the machine.
|
|
|
|
Nothing special about the machine -
|
|
486DX33, ISA, OPTI chipset, 8MB RAM
|
|
2xIDE controllers, 3 drives (Segate 130Mb, Conner 170Mb, WD 540Mb).

Any experienced people out there willing to test out
|
|
ipfirewall? Ipfirewall is a package with a kernel modification and an
|
|
application to allow you to do packet level filtering/firewalling with
|
|
your linux box. I've completed a port of this which was originally
|
|
written for BSD/386 by Daniel Boulet. I've been running it on my
|
|
machine for about a month now. For the moment, I consider this an
|
|
alpha release, although it has proven stable where I have tried
|
|
it. Installation involves applying a patch to a 1.1.45+ source tree
|
|
and compling it and the ipfirewall application. If you're not familiar
|
|
with this or your networking setup, please wait for a later release.

I have to think that, if there is to be any noticible speed difference, you
|
|
really must stick to disk-intensive applications. I would guess kernel
|
|
compilation is not THE thing to test this with.
|
|
|
|
Off the top of my head, I'd suggest this: compile the kernel with and without
|
|
hd enhancements. In each state (out of X-windows, to be scientific), mount an
|
|
empty filesystem and pipe yes into a file (yes > /mnt/tempfile) until the fs
|
|
is full--the amount of time it takes to fill up the fs should change if there
|
|
is any improvement to be had.
|
|
|
|
I'd try this myself, but I'd like to get everything else working right now!
|
|
If someone tries this (at your OWN risk! (: ), please post the results.

I use iozone. I got a 50% speed up when I went from 1.0 to 1.1.45 with
|
|
multcount 16, read-ahead 16, etc. Going to VLB with my IDE drives yielded
|
|
another 35% improvement (on top of the 50% improvement from 1.1.45).
|
|
|
|
I think that iozone does a pretty good job. Creating a new filesystem will
|
|
give you completely reproducable results, this is true. But echoing yes until
|
|
it fills up may be overkill.
|
|
|
|
Even iozone isn't really great for anything but testing big silly sequential
|
|
writes and reads. Timing the startup time of X is pretty good ;-)

Well, it just bugs me that I can reboot my system to Coherent and use the mouse
|
|
on COM2 and a terminal on polled COM4 at 9600 bps or higher (165450) without
|
|
any trouble. Running my terminal polled under Linux yields a speed which
|
|
looks, coincidentally, like it is slower than 1200 bps. Coherent changes its
|
|
polling rate depending on the bps rate of the port. This doesn't work when you
|
|
really go up in speed but it will definitely allow a 386 or even 286 to handle
|
|
9600 baud OK.
|
|
|
|
I am looking at the serial polling code now. If I come up with anything, I'll
|
|
post patches for people to try.
|
|
|
|
: It is better to listen to the rest of the world, and somehow move your

I know this might work. But, I don't want to wreck even a $5 board if I can
|
|
help it and I know that a lot of people don't want to either. Linux should be
|
|
able to poll a port at a reasonable rate. It's not too much to ask for.

I downloaded the dosemu0.53 pre alpha release.
|
|
|
|
I would like to know which kernel it is compatible with.
|
|
preferably aftre 1.1.40 or so.
|
|
I also need compatibility with ncr 53c810 scsi,
|
|
PPP and PCI bus.
|
|
|
|
please bear with me , it takes me 2 hrs to compile a
|
|
kernel on my slow 386.
|
|
|
|
I currenly run on a 386-20 but plan to move to a 486
|
|
based machine with the ncr and pci bus.

Thank you

This may be connected to your getting it to work in an xterm. You need a
|
|
different video config, I think, for things to work well on the console as
|
|
opposed to in an xterm. For an xterm I leave out all video lines while for the
|
|
console I have the video line listed above. Are you sure you didn't change it

to run under X and have not changed it back?
|

You can get delete and backspace to work in an xterm. I didn't do anything

|
|
|

If you don't use lilo on your hard drive to boot (like me), all I did was
|

change the disk line from the "disk { image..." thing to:
|
|
disk { wholedisk "/dev/hda" }
|
|
|
|
It boots right off of it and loads Stacker just fine.
|

The only other problem I have noticed is that mem does not show any EMS memory

even though I ask for it. Am I the only one for which EMS doesn't show up?

Did you try a "tail -20 /dev/zero"?
|
|
|
|
Short after bootup this stalls my system (486-66DX2, 16Meg, PCI) for about
|
|
an hour. On a system running some time, the command fails after a minute or
|
|
so with the notice " virtual memory exhausted".

Actually I've always wondered how lilo works. I understand it records the
|
|
disk block the kernel is on. But what if the kernel isn't continuous? What
|
|
is it that knows enough about the file system in order to find *all* the
|
|
disk blocks that make up the kernel?
