You should start the demon with a strict umask and set the permissions after
the socket is created.
Deriving from SocketServer.UnixStreamServer I'm overriding the server_bind()
method:
class MyServer(SocketServer.UnixStreamServer):
[..]
def server_bind(self):
"""Override server_bind to set socket options."""
self.socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
self.socket.settimeout(SOCKET_TIMEOUT)
try:
os.unlink(self.server_address)
except OSError:
if os.path.exists(self.server_address):
raise
SocketServer.UnixStreamServer.server_bind(self)
os.chmod(self.server_address,int(SOCKET_PERMISSIONS,8))
return # server_bind()
Ciao, Michael.
