Hi all,

I've written a node that sends a datagram to a specific port and IP.

The node works and runs but only sends to the loopback interface, even though the IP set is that of a different network adapter.

I've tried to setsockopt to a specific adapter but I get "operation not permitted" i'm assuming because ros doesn't have root privileges. (Look here https://stackoverflow.com/questions/4... )

I've also tried with IPADDR_ANY with no luck.

Could someone point me in the right direction?

Thanks for your help

A possible reason you didn't get any replies: this is not a ROS question, but a general networking related one.

This sort of question is best asked on SO or a forum like that.
