Description m.brock 2018-05-10 07:57:27 UTC 
Hello all,

Busybox contains both udhcpc and zcip. But the udhcpc script does not make use of zcip (or avahi.autoip) if there is no DHCP server. Could this please be added?

Kind Regards,
Maarten Brock

Also, should there not be a default zcip script, like there is a default udhcpc script?
Comment 2 m.brock 2018-05-10 09:06:54 UTC 
And another request, sorry.

But shouldn't one be able to tell zcip to give up the ip-address and stop monitoring it?

It seems to me this is a requirement if you want to stop it from the dhcp script when udhcpc finds a valid lease.

> if there is no DHCP server

How would you define "there is no DHCP server"?

What if zcip is already running? DHCP and zeroconf can be used simultaneously, right?

There is no way to write a "universal" DHCP script - there are far too many things it can't know.

Also, please read
