Because I work on a network emulator and I want to check biterros patterns so I need to access the data of the packets. An dsince my test program is written in Python, it's easier to do it in Python. > > > > All OS'es I am aware of come with a working ping implementation. > > > > > > > Does anyone have an idea about how to be able to set a source address for > > ICMP messages? > > > > Did you try not setting it? > > > > The default is probably your own IP address, which is the only > > sensible value anyway.

No, I want to do it on a machine with aliases as in: ifconfig em0 10.0.1.1 netmask 255.255.255.0 alias ifconfig em0 10.0.2.1 netmask 255.255.255.0 alias ping -c4 -S 10.0.1.1 10.0.2.1 But I think I've found the solution: my_socket.bind((src_addr, 1)) > > > > -- HansM -- http://mail.python.org/mailman/listinfo/python-list
