I have been very pleased with the getty_ps package in
SLS-1.02. If you take the time to configure it like
it says, it works great right out of the box! I use it
for uucp and logins with no problems. the debugger is
VERY nice for tuning the modems -- I'm getting uucp
xfers in excess of 1360 cps both inbound and outbound with
an el-cheapo Infotel 14400 fax/data modem as well as with
a slightly more sophisticated "turbo" modem plus (I think
it's a practical peripherals in sheep's clothing :^) )
that's in about the same price range ( approx 180.00 us )

I had this problem too.. had to assign initial passwords using the
passwd command as root. then it still wouldn't let users change
their own passwords! Finally screwed around with permissions and
ownerships until it works fine now. Settings that worked :
file mode owner group
/bin/passwd 4755 root root
/etc/passwd 664 root shadow
/etc/shadow 660 root shadow
this fixed everything (although I still assign the initial password
via root login after running useradd!)

hi!
i recently installed linux on my 486DX33. after this installation i added
a midi-card to this machine, and due to this it isn't possible to reboot
under linux. (stops at line 'detecting soundcard').
what can i do? reinstallation of linux? build new kernel? or a simple unix
command (i don't know which one..)?
please help!

Subject: C, doubles
Reply-To: ptrouton@bfsec.bt.co.uk
Date: Mon, 20 Sep 1993 09:53:57 GMT
I hope this is the right group....
I am writing a program which is basically a commandline interface, talking in commands and producing a result. All parts of the commands are read in as character. However
once in the computer, some may need to be converted to a double or integer.
e.g. (set vat = 17.5)
set, vat, =, and 17.5 are all read in as a character name. Then "17.5" is converted to a double by the command 'double = strtod(spelling)'
My problem is that I can compile the program, but once I try and run the program, it gives me a 'floating point exception error' after the command to change vat (or any other string to double conversion).
The program works fine on the Sun, but not on my 486 at home, under Linux.
How using the gcc compiler can I enable my program to work.
Thanks in advance for any help.
Paul.
P.s. thanks to everyone who helped me earlier.

If I switched back to an old LPD would it run on 1.03, I have the one from

This is a very bad idea. A Unix system without a root id is
like a life without even hope for sunshine! :) You can
make this work, but you will have a hell of a time in the
future maintaining it and adding new software to it! Harley
is definitely right about this... that's why everything stopped
working; the question now remains as to what to do the next
time you install it! I suggest leaving root alone and ADDING
a user named "kims" for yourself. You're gonna want more than
a single user on the system anyway, right?

I only have one modem and would like to use it in a dialin and dialout
capacity. Do either of these packages allow for this without having to
kill the getty manually in order to dialout?

here goes another FAQ question(?)
I couldn't find this in the FAQ.
It is probably the currently most frequently asked (and incompletely
answered) question...
EXT2-fs warning: mounting unchecked file system, running e2fsck is recommended
[EXT II FS 0.3c, 93/08/05, bs=1024, fs=1024, gc=17, bpg=8192, ipg=1592}
I ran e2fsck several times but... I am still getting this message...
what's the problem?
The problem is that both the kernel filesystem code and fsck modify the
status of the fs superblock, and the kernel filesystem code wins out.
To prevent this the root filesystem must be mounted RO at boot, fsck'ed
and then remounted RW, and then it must be remounted RO just before shutdown,
which is achieved by unmounting it.
You need versions of fsck, mount and umount that support all this, and they
are part of the bootutils-0.1 package.
Once you have installed this, you must:
1) rename e2fsck to fsck.ext2, fsck to fsck.minix, and so on.
2) put 'read-only' in /etc/lilo/config, and rerun /etc/lilo/install.
3) put the following four lines in /etc/rc:
fsck -A -a -av # check filesystems while root is RW
mount -n -o remount / # remount the root so it goes from RO to RW
rm -f /etc/mtab* # remove stale mount table
mount -A -a -av # mount all, write new mount table
[note: I am typing from memory; if I remember well the above sets of
options *must* be typed exactly as shown, in exactly the order given.
In particular the -A option *must* be the first, and either fsck or
mount, I don't remember which, *must* have the 'a' option replicated
because of a bug; you also *must* specify the 'n' option when remounting
the root.]
4) make sure that your version of shutdown/halt/reboot does call
'umount -a' before stopping the system and after having killed
all processes.
5) make sure that your /etc/fstab lists *all* filesystems you want to mount,
including the root; filesystems you don't want to mount at boot up time
can be flagged as 'noauto', but then you must copy the 'noauto' patch
from the 'bootsys' package.
The only thing I am a bit unsure about is whether one needs to reboot
in case fsck had to repair the root; IMNHO I think this is not
necessary, remounting *ought* to reload the updated filesystem
information.

Subject: PROBLEM: X386 freezing up station
Date: Mon, 20 Sep 1993 14:45:37 GMT
Hi,
I got a problem when running X386. Sometimes the X-Server freezes
the complete station. All X-Clients seem to stop ( clock doesn't
update, xload doesn#t update ). I haven't tried to login into my
station from remote, but i'm quite sure that the machine is hanging.
The problem is that this doesn#t hppen all the time. Sometimes
I can open lots of shell-windows and anything will work fine, but
othertimes the statiob hangs after opening just two windows.
I think my configuratuion in Xconfig is ok. I can create lots
of processes if I don't use X386.
I'm running linux 0.99p12 and XFree 2.0. Window-Manager is olvwm.
Hardware: Cyrix 486DLC, VGA 16 ET4000 SVGA card, 8 MBYte RAM,
16 MByte Swap space
Question is: Is the defect described above a known failure
(I hanve't found anything about it in README files).
Can I do anything to avoid it?
I've got a second problem:
The size of my swap partiotion is about 22 MByte (shown by fdisk).
I did a mkswap with the given size. When I say swapon /dev/xxxx
I get 16xxx KByte swap partition activated. Why is there some swap
space left unused ?
Thanks,
