System(/tmp/netcid.py 2000 Joe)

That did it :-) Thanks guys.

BTW, for those interested, I didn't have to double-fork:

==
#!/usr/bin/python

import socket,sys,time,os

sys.stdout = open(os.devnull, 'w')
if os.fork():
sys.exit(0)
else:
#Here, send broadcast
==

[asterisk-users] [Linux/Python 2.4.2] Forking Python doesn't work

2008-02-13 Thread Vincent 
Hello

When a call comes in, I'd like to fork a Python script that
broadcasts a message so that users see the CID name + number pop up on
their computer screen, and simultaneously ring their phones.

The following script doesn't work as planned: It waits until the
script ends before moving on to the next step, which is Dial():

===
exten = s,1,AGI(netcid.py|${CALLERID(num)}|${CALLERID(name)}) exten
= s,n,Dial(${MYPHONE},5)   
===
# cat netcid.py
#!/usr/bin/python

import socket,sys,time,os

def sendstuff(data):
   s.sendto(data,(ipaddr,portnum))
   return

sys.stdout = open(os.devnull, 'w')
if os.fork():
#BAD? sys.exit(0)   
os._exit(0)
else:
now = time.localtime(time.time())
dateandtime = time.strftime(NaVm/%y NaVM, now)

myarray = []
myarray.append(STAT Rings: 1)
myarray.append(RING)
myarray.append(NAME  + cidname)
myarray.append(TTSN Call from  + cidname)
myarray.append(NMBR  + cidnum)
myarray.append(TYPE K)

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET,socket.SO_BROADCAST,True)

portnum = 42685
ipaddr = 192.168.0.255

for i in myarray:
sendstuff(i)

#Must pause, and send IDLE for dialog box to close
time.sleep(5)
sendstuff(IDLE  + dateandtime)
===

In another forum, people told me that I should fork twice. Is that
really necessary?

Thank you.

Vincent,

try to use System() instead of AGI()

If you want it to detach the program from it's parent you
need the double fork yes.

Thanks for the confirmation, but when doing this, the NetCID
application no longer pops up, regardless of whether I put the NetCID
code in the second parent or second child:


exten = 9300,1,AGI(/tmp/test5.py|${CALLERID(num)}|${CALLERID(name)})
exten = 9300,n,Dial(${MYPHONE},15)

# cat test5.py 

#!/usr/bin/python
import socket,sys,time,os

def sendstuff(data):
   s.sendto(data,(ipaddr,portnum))
   return

log = open('/tmp/output.txt','w')

sys.stdout = open(os.devnull, 'w')
if os.fork():
#Parent
log.write(Step 1\n)
log.close()
os._exit(0)
else:
#Child
os.chdir('/tmp')
os.setsid()
os.umask(0)

if os.fork():
#Parent
log.write(Step 2\n)
log.close()

now = time.localtime(time.time())
dateandtime = time.strftime(%d/%m/%Y %H:%M, now)

myarray = []
myarray.append(STAT Rings: 1)
myarray.append(RING)
myarray.append(NAME  + cidname)
myarray.append(TTSN Call from  + cidname)
myarray.append(NMBR  + cidnum)
myarray.append(TYPE K)

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
 s.setsockopt(socket.SOL_SOCKET,socket.SO_BROADCAST,True)

portnum = 42685
ipaddr = 192.168.0.255

for i in myarray:
sendstuff(i)

time.sleep(5)
sendstuff(IDLE  + dateandtime)
os._exit(0)
else:
#Child
log.write(Step 3\n)
log.close()
os._exit(0)


Has someone already forked a Python script successfully from Asterisk
through AGI?

Thanks.

The arguments to System() are a bit different.  Put it in just like you would 
type at the command line.
