| |
It appears that there has been a change in the handling of sending packets to the broadcast IP address between 2.2 and 2.4.
I have an embedded system that has only local LAN access, no default route to the net as a whole. We're running 2.2.17 currently, and we use bootpc to configure the system.
We're now looking at converting to 2.4 and are running into a problem with bootpc getting "Network is unreachable" errors.
After some digging, it appears to be due to the fact that I don't have a default route specified, but this is on purpose.
strace shows that bootpc is trying to run sendto() with a destination of 255.255.255.255, and this works fine on 2.2 and fails on 2.4. Is this the desired 2.4 behaviour?
What is the appropriate configuration for my setup? Do I just add a route to 255.255.255.255? Can I set it up to broadcast out all devices automatically, or do I need to do explicit failover management? Should I be looking to fix bootpc instead?
Thanks,
Chris
