Re: Socket bound to 0.0.0.0 never receives broadcasts with non-zero IP source address

2015-04-08 Thread Daniel Corbe
If nobody answers this question by the time I get home I'll try and help; however, in the mean time I do have a couple of suggestions. Have you tried writing the equivalent program in C using the sockets API? IE is this a python specific problem or a sockets problem in general? The second thing

ifconfig greX create disables IPv6 forwarding

2015-02-09 Thread Daniel Corbe
For some reason, every time I create a GRE interface on a FreeBSD IPv6 gateway, net.inet6.ip6.forwarding is disabled. As long as I manually re-enable it with sysctl, both the GRE tunnel and the IPv6 network behind this machine will continue to work; however, it's certainly far from ideal. There'

Re: Can multiple apps listen for TCP on the same port?

2014-12-01 Thread Daniel Corbe
Generally the answer to your question is no. Two applications cannot occupy the same port on the same protocol at the same time. To expand on this answer and to hopefully shed some light on why the behavior you're observing with your application is absolutely correct; the calling application (in

2014-07-16 Thread Daniel Corbe
I hope this it the right place to ask questions about netmap. I'm toying with the idea of writing a netmap-based OSPF implementation because bird's OSPF implementation isn't as good as its BGP implementation, quagga doesn't scale well and openospfd doesn't compile on 10-RELEASE or CURRENT. But I
