solution for a quick/robust/secure broadcast issue

[bruce]

Hey patrick.

couldn't really find any good pointers on this.

any step by steps you can point me to.

ie, boxA with ipA is running mysql and has name boxA

the dhcp of boxA might change day to day

user on boxB wants to be able to get ip of boxA

how can avahi be used in this case?

thanks
