I feel like an idiot.
I'm trying to get the good ol', command line editing and history going
on. So I can use vi commands to move back and forth in my command
history from the command line, and use vi commands to edit the command
line, etc. you know what I"m talking about.
I'm running RH6.2. Now, I actually got it to work one day, for about 10
seconds, and then it stopped working. I don't remember what I did, it
was a couple months ago and I got frustrated and said screw it.
So anyway, I'm trying to get it working again, I can't live without it,
and so I've put the following in my .bash_profile :
export EDITOR=vi
export VISUAL=vi
set -o vi
and of course source the file again, and it still doesn't !@#$ work.
What the hell am I doing wrong?

Leonard Peltier was jailed in 1976 for the murder of two FBI officers
that even the prosecution admitted there is no evidence that he
committed. But in order to deter the growing call for Native American
rights and autonomy, in the form of the American Indian Movement,
Peltier was made an example of. It's the year 2000, why is this man
still in prison?

And what's wrong with that? If you want linux to succeed on a wide scale
it HAS TO get easier to install and configure for the 'common man' as you
say. It is funny how the instinct to take shots at microsoft also
translates into taking potshots at anything that even remotely resembles
their OS.
Once the newbie learns the ins and outs of linux, he or she can then tweak
it how they want. Isn't that the beauty of the thing?

Tell us _exactly_ what you did and _exactly_ what happened. Post exact
copies of all commands and all error messages. Don't be afraid to be
verbose.

These 2 aren't need for command line editing (they should be set
anyway).
>set -o vi
That should work, try it at the command line. If that fails do a ps.
Does bash show up or some other shell? Try typing bash, then set -o vi
if that fails then there is something very wrong.

Hi,
How can I make sure that non-privilaged users can mount /dev/cdrom too?
It used to work this way, but not any more (after I started treating
/dev/hdc (cdrom) as a scsi device using scsi emulation)
Thanks

Actually, the piracy thing is incorrect I believe. It's what the
companies want everyone to think so the public (and courts) will be
more sympathetic to them. So they say they are just trying to stop
pirates, but all you need to do to pirate is make a bit for bit copy,
you don't need to be able to de-encrypt or even to be able to play
the media, as you can still sell your copy to someone who does have a
player. I think it's all about control over the players.

Here are the original settings of fstab:
/dev/hdb1/ ext2 defaults 0 1
/dev/hda1/ windows vfat defaults 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy vfat defaults,noauto,user,exec,rw 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,noauto,user,exec, 0 0
/dev/hdb2 none swap sw 0 0
Here's what I ended up with:
/dev/hdb1 /ext2 auto,user,exec,rw 0 1
/dev/hda1 /windows vfat defaults 0 2
proc /proc proc defaults,rw,user,exec,auto 0 2
/dev/fd0 /floppy vfat defaults,auto,user,exec,rw 0 2
/dev/cdrom /cdrom iso9660 defaults,auto,ro,noauto,user,exec 0 2
/dev/hdb2 none swao sw 0 2
When I try to get in I am given the choice of hitting ^d which
reboots or entering the root password which gives me the
prompt (none) #. Everything is read-only.
Please don't ask me how I arrived at the settings. I was careless
because I assumed that I would be able to copy the backup file
if things didn't work out.
Thanks for any help!

Substitute in the fields on your system, I'm using a FreeBSD box here with
psutils and probably a different version of ps and hence a different
formatting scheme, the principle is the same though.

I have a copy of IBM's _Technical_ _Reference_ for the pc/xt. It contains
the source for the BIOS. What Compaq et al actually did was "clean-roomed"
it.

No one is interested in "ripping" your software. The reverse engineering
under discussion here is of the hardware, so that we can learn enough about
it to write software that uses it.

I don't see any errors in any of the above.
One more thing is, i used 'ifconfig eth1 10.10.0.1' and 'ifconfig eth0
138.26.80.80' commands to re-initialize those interfaces and pinged with
those IPs and observed 95% and 97% abnormal packet losses.
The output for the 'route -n' command is as shown below.
Kernel IP routing table
Destination Gateway Genmask Iface
10.10.0.1 0.0.0.0 255.255.255.255 eth1
138.26.80.80 0.0.0.0 255.255.255.255 eth0

127.0.0.0 0.0.0.0 255.0.0.0 lo
0.0.0.0 138.26.1.2 0.0.0.0 eth0
Further info:
1. As i am using DNS i am having only one entry in the /etc/hosts, that is
for localhost with 127.0.0.1 IP
2. /proc/interrupts shows Interrupt 5 for eth0 and Interrupt 10 for eth1
3. When i used '/etc/rc.d/init.d/network stop' and '/etc/rc.d/init.d/network
start' i observed these following lines in /var/log/messages from which i am
unable to understand anything:
net.ipv4.ip_forward = 0
net.ipv4.conf.all.rp_filter=1
net.ipv4.ip_always_defrag=0
kernel.sysrq=0
Ping 138.26.80.80 itself is not successful that is the most bothering part
of this episode above pinging any external machine.
If you need any additional info please let me know.

This sets the default editor? This hasn't anything to do with command line
editing and history.

set -o vi should work, but I've had problems before with my TERM,
try
export TERM="xterm";set -o vi

A journaling file system is a fault-resilient file system, in which data
integrity and sturcutres is ensured because updates to the file and directory
structure are written to a serial log on the disk before the original disk log
is updated. In the event of a crash, files and directory structures can be
restored. ext2fs does not provide any journaling at all, xfs is a journaling
FS created by Silicon graphics.
NTFS if my memory is right even supports some sort of journaling..
