Re: [pysnmp-users] Sending a broadcast SNMP packet

[Ilya E. <il...@gl...>]

Try setting the 'BROADCAST' flag to the socket your are sending SNMP out:

>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
>>> s.sendto('a', ('111.112.214.255', 1611))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
socket.error: (13, 'Permission denied')
>>> if hasattr(socket,'SO_BROADCAST'):
...    s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
>>> s.sendto('a', ('111.112.214.255', 1611))
1
>>>

The socket object is available as a 'socket' attribute 
of role.manager class instance.
