Indeed, split by commas.

For multiple NICs, would this be comma-separated?

Thanks, Jarrod!



Do you know in what version that was added?

Another example of how we've been derlict in documentation...  There is now a 
way to indicate nics to ignore for netboot purposes, in a little known file 
called service.cfg:

# cat /etc/confluent/service.cfg
#[http]
#bindhost = /var/run/confluent/httpapi

[netboot]

I most recently did this with a firewall rule, but agreed, it would be good if 
there were a better way. And maybe there now is. There was not in the version I 
was running at the time.

In xCAT it was very easy to set the tftp/dhcp listening interface in the main 
config file, so that nodes would get a pxe response from the desired interface 
and not conflict with any other dhcp servers.



My Confluent server is configured to start TFTP but nodes are not getting a pxe 
response from the non-routable deployment network.  Instead they are getting 
responses from the enterprise network.  How can I force tftp/dhcp to use a 
particular interface on the head node?



deployment:  10.13.13.0/24<http://10.13.13.0/24>

Enterprise (really home): 192.168.0.0/24<http://192.168.0.0/24>

DHCP and DNS handled by FreeIPA server
