[asterisk-users] Running asterisk as non-root

[Jerry Geis]

I found a page that assisted in running asterisk as non-root.

My question is why is the default install not more friendly in this
manner???

I mean basically the instructions changed the permissions to allow GROUP
write, so 775 instead of 755 and changed the astrun to be a directory

Why doesn't the default install do this? Seems logical to me. I installed
11.25.1

Thanks,

Jerry

Re: [asterisk-users] While loop inside recursive calls

[Jonathan H]

Well, I've never seen dialplan like that - is this a very old version
of Asterisk, or psuedocode?

Anyway..

A subroutine MUST be balanced, and if a subroutine is aborted before
it reaches return, you'll be in all sorts of hell.

An example:

You make a subroutine of some sound files you want to loop through to
make an IVR menu.

You call it using Gosub. Someone presses two while the third of 5
tracks is playing.

The stack will then be unbalanced and you'll then be in a potential
world of stack overflow and unknown hell.

So keep the gosubs for things where they cannot be interrupted.
Playback is fine. Background and ControlPlayback is not. See?

Here's a solution to this problem which caused me HUGE amounts of
headaches early on (and I mean days and nights on end!)

Hope it helps...

[asterisk-users] While loop inside recursive calls

[Ethy H. Brito]

Hi All

What happens if I, inside of a while/endwhile loop, call recursively a
macro that itself has another while/endwhile loop and calls exitwhile() inside 
the
recursive call?

[macro-recursive]
instance=$ARG1
if instance>3
macroexit
X=1
_var1=""
; recursive loop
while(Dcondition)
_var1=value_${X}
recursive(instance+1)
if var1==""
ExitWhile()
X=X+1
some_Dcondition_changing
bla...
bla...
EndWhile
macroexit

[some_running_context]
; Main loop
while(Zcondition) 
recursive(1)
if (var1=="")
ExitWhile
some_Zcondition_changing
bla...
bla...
endwhile
more_intructions
MacroExit

The problem I see is if I reentry "macro-recursive" a the second time,
Macroexit returns to "more_instructions" at "some_running_context" (just after
the Main Loop endWhile). It should return to 'if (var1=="")' at the previous
"macro-recursive" call.

It is like the second call to "macro-recursive" overwrites the first
"macro-recursive" while/endwhile loop return point, and the second ExitWhile
exits from the while/endwhile at "some_running_context" and not from first
"macro-recursive" instance.

In short: second (and subsequent??) call to macro-recursive is ExitWhile()ing
from "some_running_context" while loop. First call exits ok.

Any directions to share?

Is this explanation too complicated to understand?

Regards

Ethy

There should be no need for a reboot. Long live your system.

What kind of change? Technically it would only take running 'dahdi_cfg'
to apply that change. However that may not be enough. Depending on the
specific change.

> service dahdi stop

It only got faster. No need to deconfigure anything in Asterisk (This
happens on its own. At least on Asterisk >= 13). No need to unload and
re-load any modules (And why would you? Just to run dahdi_cfg?).

But anyway, if merely running dahdi_cfg is not enough, try:

  dahdi_span_assignment remove
  dahdi_span_assignment add # or: auto

This should also configure DAHDI and register spans with Asterisk
(again: >= 13). If there are still problems with asterisk:

  asterisk -rx "dahdi restart"

So it is no longer possible to make changes on dahdi parameters
without rebooting the machine ?

I think in the early days it was possible something like this:

make a change in /etc/dahdi/system.conf
asterisk -rx "module unload chan_dahdi.so"
service dahdi stop
service dahdi start
asterisk -rx "module load chan_dahdi.so"

No. As I mentioned, that is meaningless.

There are various commands that show the status at various levels:

lsmod | grep ^wctdm24xxp
dahdi_hardware | grep 'wctdm24xxp\+'
dahdi_span_assignments list
lsdahdi
asterisk -rx 'pri show spans'

What exactly do you consider as "status of dahdi"?

git log #?

The tarball has no changelog and thus it is not packaged. Sorry.

Most distributions ship an out-of-date version of mono, so you may need to 
compile that from Source Code first.

As a general rule, you should never, ever run any binary that was not compiled 
either by yourself or your distro -- and if anyone ever offers you a binary 
without the Source Code, walk as fast as you can in a different direction, 
because it is likely poisioned.

Re: [asterisk-users] How to install and configure Dahdi from Debian Stretch repo ?

[Olivier]

Thanks to Tzafrir help, Now I have an Asterisk-Dahdi system installed from
Stretch repository.
This system has a Digium HX8 card with BRI modules, Asterisk 13.14.0, Dahdi
2.11.1.
BRI spans appears as up and active but I've not tested them yet:
CLI> pri show spans
PRI span 1/0: Up, Active
PRI span 2/0: Up, Active
PRI span 3/0: Up, Active


I'm still having some questions:

1. I can't find any /etc/init.d/dahdi file in my newly built system so
"service dahdi status" (or systemctl status dahdi) fails with:
Unit dahdi.service could not be found.
Shall I worry about this ?

2. Where can Dahdi 2.11.1 Changelog file be found ?
In http://downloads.asterisk.org/pub/telephony/ ?

Best regards
