asterisk users - Jul 2006 - vserver (Debian) - no tty: howto use /usr/sbin/safe_asterisk with "-c" for color CLI?

Salve *!

I'm using asterisk for a while and now I want to have a colord CLI.
I have apt-get install asterisk/testing, that is asterisk 1.2.7.1

I use Debian stable/testing on a vserver with any /dev/tty*.
So, of course, I comment out "#TTY=9" inside /usr/sbin/safe_asterisk.

/etc/init.d/asterisk start
 calls
/usr/sbin/safe_asterisk

root      5757     1  0  1149 1348   0 16:08 pts/30   00:00:00
/bin/sh/usr/sbin/safe_asterisk -g -vvv -U asterisk
asterisk  5758  5757  0  4502 7992   0 16:08 pts/30   00:00:00 
\_/usr/sbin/asterisk -g -vvv -U asterisk


When I start asterisk by hand with "asterisk -cgvvv" 
I got a colored CLI ;) 

but inside /usr/sbin/safe_asterisk (started by
/etc/init.d/asterisk - with "-U asterisk") 
or inside /etc/init.d/asterisk itself all my tries
to use "-c" as additional parameter faild. ;(

E.g. I changed line 52 inside etc/init.d/asterisk
PARAMS="$PARAMS -U $USER"
PARAMS="$PARAMS -c -U $USER"


This does run the CLI  with color :)
also with color for asterisk -rcvvv

*but* there is an fast running repeating output
after running /etc/init.d/asterisk start

 Use EXIT or QUIT to exit the asterisk console
 Use EXIT or QUIT to exit the asterisk console
 Use EXIT or QUIT to exit the asterisk console
 [...] 


The handycap of vserver is, that as root@guest you can't creat devices
yourself. I think asterisk is also reading from /dev/tty9, so a
ls -s /dev/null /dev/tty9  does not help (tested).

Does somebody have an idea how to deal with this?
Can I run asterisk with color CLI without a TTY*?

Greetings,
rob

safe_asterisk has a flawed logic: it assumes that the tty device will
always exist. Thus it is not suited for use with screen.

However wouldn't it be better to tell asterisk to have colors even in a
remote terminal unless you use -n?

See attached patch for a possible route. I don't remember if I tested
it, though.

Some RTFM from asterisk(8):

       -c     Provide  a  control console on the calling terminal.  Specifying
              this option implies -f and will cause asterisk to no longer fork
              or detach from the controlling terminal.

The fact that you only get colors there i a byproduct. -c simply tells asterisk
not to act as a daemon.
