Hi, I need to re-open the thread blow. The situation is still the same. The HUP signal does not trigger reloading of subnet declarations in own hosts file (Version 1.0.35). After a quick view to the source code, file src/net.c shows in line 658 would reload subnets when using StrictSubnets only. But why? With StrictSubnets it doesn't make sense to me.
I did a quick check and removed the if (strictsubnets) to let HUP signal reload sunets and it works. So why is the update of local subnet declaration with HUP signal possible in StrictSubnet mode only?  Armin Am Sa., 5.

I rewrote the hosts/<my host> file (adding a Subnet) and sent the HUP signal. But with USR2 signal, each node and the local itself doesn't show anything about the new Subnet entry. Did I miss something? I need to stay with version 1.0. Armin
