If you are going to allow logins and file transfers from the
Internet, I'd get rid of telnet and ftp as well, then set up ssh
(http://www.openssh.com/)
I'd look into a firewall using ipchains, or the new iptables. A web
search should turn up a *lot* of info on that subject.

I too had this same problem. near as I could tell, everything was installed
correctly.
I was using kernel 2.4.0 on a RedHat 6.2 system. HP 7200i drive with ide-scsi
emulation. I could read fine from the cd, using the scsi emulation, but not
write. My error messages were simmilar to yours. My solution was to download
the latest cdrecord alpha release from
ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/alpha/ and compile it following the
instructions...
The compiled version worked fine, the RedHat 6.2 cdrecord 1.9 rpm packages did
not...
Cheers

Subject: lilo.conf and boot up questions
Hi all,
I have a question about lilo.conf and boot up uner RH 6.1. Please give me a
hand if you can.
I found this line in my lilo.conf after the "image=" line:
initrd=/boot/initrd-2.2.12-20.img
What does this line do? I looked thru 'man lilo.conf' and could find any
thing on initrd .
My RH 6.1 server failed to boot up after a cold reboot. The boot process
stopped after mounting only the root file system in read-only mode. All
other filesystems in /etc/fstab were not mounted. /sbin/init was not
executed and I was booted into a /bin/sh shell instead.
I could not edit lilo.conf becaue /etc is in the read-only root system.
What went wrong? Any idea?
Thanks.

You can do what you want with the -C (change directory) option:
tar cf data.tar -C /data/thisproject/veryimportant/format 20-01-99/file1.txt \
... -C /data/thisproject/othermachine 16-08-01/file1.txt
You will need a script to massage the files2tar string into this form.
(GNU tar has a long option variant: "--directory=DIR" is equivalent to
"-C DIR".)

Subject: ssh question
Date: Thu, 8 Feb 2001 21:54:36 -0800
Thanks to Sak Wathanasin and David Efflandt for getting me straightened out
with permissions to run openssh! If I set ".ssh" to 700, and authorized_keys
to 600 then everything works fine as you said it would.
One problem though, why do your permissions work and the ones that I was
using didn't?
All of the permissions that I was using were more "open" than yours. For
example, I had 755 for ".ssh", and "664" for authorized_keys. So if my
permissions were less restrictive than yours why do yours work and mine
always yield "RSA authentication error"? After I got it working with your
permissions I set it back to mine and got the same authentication error.
Can anyone explain this?
Thanks,
Tom.

Howdy Jim,
I take it from your response that if I leave telnet and
ftp in /etc/inetd.conf that this means others can login on my box.
I thought I had to leave them on to ftp/telnet out. What I really
think I want is akin to a telephone with no bell. I can call out
but noone can call in.
Is my logic broken?

What was the error message you got?
have you tried to supply the "init=/sbin/init" option when you boot.

Because they should be at least as restrictive, or ssh will complain
