I'm running bash, which I have compiled myself.  I might suspect the
shell, except that:
1) it doesn't happen on the VCs, and
2) the HUPing is also occuring while it is sitting at the login
   prompt.

Any other takers?

Was I missing something or wasn't last weekend meant to be the release
of the linux with TCPIP code?  Obviously I was wrong. Can anyone tell
me when?  I wish to setup a standalone machine that will be a test case.
If I can show it works I will be moving it eventually onto a LAN. I don't
even need drivers for ethernet cards yet... just to show Linux will have
that ability by showing "finger" and "telnet" commands working.

You are obviously not up to date with xdvi. Try to get a new version
(pl15 or pl16), recompile (don't forget to add -DGREY and -DMAKEPK,
remove -DMSBITFIRST and change SHORT to LONG on the Imakefile DEFS
line), and shiver! Even for this tiny application you don't need DOS!

Anyone for an alternative on

rather smoothly consdering that this is the first time I use curses.
However, I have one problem: How can I make curses write to the
standard error instead of the standard output? (since if writes to the
standard output it is useless for something like 'rz < /devttys1 >
dev/ttys1' ..etc.). Any help would be greaty appreciated.

space, is there any particular order they should be in?

When using mkfs and mkswap, is there any advantage to specifying 
a number of blocks smaller than the device has? (bad sector mapping?)
Or will it even work if you use a smaller number?

I ask this because I'm still trying to get linux to install to a HD
partition, last time I ran install it told me that the device was out
of space for the very first file copy (installing the root file system
on the partition).

I would like to try to program a little terminal for linux that
would just copy keyboard input to the modem-tty, and everything
from the modem to the console. Under MSDOS this is easy, because
you can eat up all the CPU time checking for keyboard input and
modem input in a tight wait loop, but how should one go on doing
this under a multiuser/multitasking system?

Is there any way to make "interrupts" or call-backs to a user-
specified function, or does the program have to fork() into
two parts, each of which is waiting for input sitting in a
blocking read function?

Usually when I ps while running C-Kermit I see two processes
called "kermit", so obviously this is what kermit does. I'm
just wondering is there a better way, and if there isn't,
should there be.

Thanks for any help/advice.

that it was a PS/2 mouse (it's got 'PS/2' written all over the manual and the 
mouse itself!) but Linux can't seem to find it. There is some weirdness in the
startup code where it tries to read something out of the CMOS ram, and sets a
flag variable. Obviously this isn't as standard away of detecting a PS/2 mouse 
as the author assumed. Could it be changed to a simple hardware check?!? I
have the Pheonex BIOS, which is rather standard, but might have nothing to do
with whats stored in the CMOS ram.

I managed to corrupt my filesys, so I was going to restore it from
a backup I had made 30 minutes earlier (yeah, I knew I was going to
be doing some weird stuff, so I backed up...)  Anyways, when I
backed up, I did this:

cd /; tar -cf - .* [^m]* | compress > /mnt/c:/linux/backup/921001.tz

Obviously, I tar'ed entire drive (minus the mnt dir), onto my msdos
filesys.  So, when I tried to restore, I did this:

cd /; cat /mnt/c:/linux/backup/911001.tz | uncompress | tar -xvf -

Anyways, then I rebooted.  The system hung.  So, I re-mkfs'd
my root fs and tried it again.  Then, I fsck'd the drive before
rebooting.

  *** fsck reported the superblock was corrupt ***

I don't see a way that cat | uncompress | tar should corrupt a
superblock.   I've managed to get my fs back, when i uncompressed
1 dir at a time.  So, I'm not dead in the water.  But, it's kinda
annoying not to be able restore from a backup.

Info:
  intel 386/33
  5 mb ram, 7mb swap
  root fs is minix
  921001.tz is about 15mb
  tseng 4000 1mb video
  ami bios
  maxtor 7213a hd (never had any timeouts)
  ran backup/restore as root
  using cat/tar/compress from root.97.1 image

Any suggestions?  If not, at least consider this a warning.

Simply because there are non-Windows applications that work very well

 I'd appreciate any help on the following problem:

Environment: linux 0.97pl6, 8 Meg memory, 10Meg swap.
Hardware:    50MHz 486, 213Meg Maxtor HD.

 Symptoms:

  Arbitrary programs randomly break down with signal 11 (seg fault)
and dump cores of large size.  Programs more likely to break down 
involve intense disk access, like ld or make. Many times the FS 
is badly corrupted, with lots of 'block used before' messages. 
Several times, the root device seems to have vanished or have been 
umounted, i.e., cd / followed by ls gives nothing. Logins get, off
course, disabled since there is no root file system. After reboot from
the floppy, everything is OK.

 I understand the problem may be related with the particular HD I
have. Any fixes ? BTW, after a program breaks down once, further
invocations automatically fail.  I assume the file is in cache and has
something wrong with it. After a while, they will work again.

 Thank's in advance

Hello LINUX world,

Thanks for the nice FREE port of the un*x operating system on the 386+
platform. I do not consider myself a hacker but LINUX will help me a
lot into learning the way un*x works at the (user|root|sysadmin|...) level.

I have successfully installed the SLS distribution of LINUX on my 386sx PC
while leaving a partition available for MS-DOS (/dev/hda1). After I installed
MS-DOS 5.0 on drive C: I wanted to boot it but nothing happened. I got the
power-on self tests and then silence, dead, not even a single message.

I can boot either LINUX or MS-DOS from floppies but MS-DOS will not boot
from the hard disk. I have tried the same on another PC, same results, drive
C: won't boot.

Would it be possible that LINUX put some information on the hard drive that
makes a DOS partition unbootable? If so, is there a cure to the problem and
what should I do?

Many thanks in advance.

Configuration:

	386sx	16MHz
	Phoenix 386 BIOS V1.01
	5MB RAM	(1MB (640KB base + shadow BIOS + some EMM) + 4MB extended)
	387sx
	Seagate ST-08 IDE+Floppy controller
	Seagate	ST3144A Hard drive
		/dev/hda1	15MB DOS partition set active
		/dev/hda2	50MB LINUX system partition
		/dev/hda3	50MB LINUX user partition
		/dev/hda4	10MB LINUX swap partition
	/dev/fd0 is a 3.5" 1.44MB floppy
	/dev/fd1 is a 5.25" 360KB floppy

	For more details do not hesitate to contact me.

Many thanks again (I hope there is a fix to the problem)

	   This is just IMHO, but I think the sad fact is that as
   inefficient as we may feel Windows and the soon-to-be-crowned Window
   NT are, most users would find Unix difficult to learn and risky to use
   ("What, rm * will PERMANENTLY delete everything? Ugh!"). Frankly, to
   most people, Windows or Mac OS are as good as it gets in GUIs these
   [...]
   saying is that people tend to stick with what they know unless there's a 
   compelling reason to change -- and there isn't here, since people
   can get done what they need to get done in DOS. They don't know how 
   ugly their OS is on the inside, or that there's something wrong with 
   having to copy all the files in a directory and then delete them just to 
   move the directory somewhere else, and they don't care. Only a very few
   will get excited about fee Unix. I agree that we should do what we can
   to reach those few, but let's not expect everyone to come running...

How about money as a reason?  And I'mnot talking of just the OS.  In a
recent magazine (don't remember which, but I think it was a local one)
there was a comparision of setting up a fairly typical LAN with either
the ms-dos, novell, etc, or Unix software.  With the nescessary
hardware and software, for systems administration and work.

The unix system was markably cheaper than the more MSdos one, and at
least in *my* opinion (surprise!) a lot cleaner.

But I agree, people will find it hard to migrate from the familiar
environment of ms-dos.  Perhaps we could put together DOS-emulating
startup files? (Yuk!)

Well, I can't provide much help, but I just wanted to say that at least the
UltraStor support in 0.96c pl2 works like a charm.  I am using the most recent
SCSI patches from headrest.woz.colorado.edu (from around the middle of July or
so, I think), and my UltraStor 14F with Maxtor LXT213SY setup has been very
robust, even under heavy loads.  As I understand, this is the same SCSI driver
code that is in 0.97, so I wonder what could have happened to break it.

Anyway, I guess that downgrading to 0.96c is kind of regressive, but it may
be a way for anyone that's having problems to get a working linux system; the
reason that I chose to stay at 0.96c was because of various problems reported
with earlier patch levels of 0.97.  I have a linux system that is working 
perfectly and I didn't want to risk "messing it up."  I imagine that I will
have to upgrade when version 2 of the SCSI drivers is released; the current
drivers are a little slow for my taste (but like I said, they work great 
otherwise).

I checked 'demand'-word from the word book, but your sentence

As I said above, we will do the following:
1. Press release for computer magazines/journals.
2. Press release for newspapers.
3. Collect the list of magazines and journals usefull for Linux
   article -- we should make a list for those magazines who could
   do bigger article on Linux.
4. Decide who (many people) will send the press release to

Oh well, if the local newspaper writes articles on Ramanujan,

perfectly ok to send a press release to any reasonable newspaper;
they will make the article as they wish -- we just include
