I don't think "bind -f file" when called from a
script will work. Because when script exits 
keymap will be back to original one. Child process
can't change environment of parent.

Hi,

I want users to be able to telnet into my linux box.
So I did 
#>chkconfig telnet on

and added in /etc/hosts.allow
in.telnetd: ALL: ALLOW

then
#>/etc/rc.d/init.d/xinetd restart

I was unable to telnet into the box:
It says connection refused, it does't even come 
until login prompt. So I think telnetd is not
configured properly. So what is wrong in above
process???

Regards
Venkat.

Have a look in /etc/xinetd.d directory

You need to go into /etc/xinetd.d/ and edit telnet. It has one parameter
disable = yes, change that to no then restart xinetd.  I don't think that
chkconfig will handle services within xinetd's realm.

A couple of things.  "chkconfig telnet on" does update 
/etc/xinetd.d/telnet parameter "disable = yes" to "disable = no" 
and restarts xinetd automagically.


I really think his issue is the default firewall config for the host.

If "telnet localhost" works from that host, that is the most likely cause.

"netstat -an | grep -i listen" should report something like

tcp        0      0 0.0.0.0:23          0.0.0.0:*           LISTEN 


He might try "service ipchains stop" and test the telnet connection then.

Hi

After doing stty erase "^B", it is not not erasing
after I do ctrl-B.

Is anything wrong the way I am doing, to set "^B"
to be the erase key.

Glynn,
  When man says "stty - change and print terminal line settings",
  and readline(3), needs to be configured through inputrc..
  which is unaffected by stty.. !

  Something looks awkward.. right ?
  why readline does not bother stty ?

A mistake is just another way of doing things.

stty controls the settings of the kernel's tty driver. However,
readline explicitly puts the tty driver into "raw" mode, overriding
any previous settings.

It does this so that it can provide complex line-editing facilities,
similar to those found in a text editor.

The kernel's tty driver only provides very basic line-editing
facilities, i.e. the ability to erase the previous character, the
previous word, or the entire line.

Also, the line-editing facility is only available in canonical (aka
"cooked") mode, where an entire line of input is returned when the
Return/Enter key is pressed. If a program wants to read key presses as
soon as they occur, it has to put the tty driver into "raw" mode. 
Clearly, the tty driver can't provide line-editing in this mode (once
a character has been sent to the application, the tty driver can't
"unsend" it).

What isn't erasing? bash?

"stty erase ..." sets the erase key which is used by the kernel's tty
driver. It will work for programs which leave the tty in "cooked"
(ICANON) mode. Try running "cat" without arguments to check the
behaviour of the tty driver.

However, a program which sets the tty to "raw" mode will receive all
key codes immediately; if it wants line editing, it must implement it
itself. The GNU readline library (normally used by bash and several
other programs) does this, so you will probably need to configure
readline separately, via the ~/.inputrc file. See the readline(3)
manpage for details.
