Good Afternoon All,
We've got Ubuntu NetSUS server staged up but I'm seeing some strangeness in the way DHCP is behaving. I've got dhcpd configured within the etc directory, but I just noticed there's another dhcpd.conf file in
/var/appliance/conf

So I've really got two questions:
1. which config file gets used in the netboot process? 2. The errors I'm getting look like this
Jun 13 15:14:23 calculon dhcpd: DHCPACK to 10.2.90.161 (c8:2a:14:3b:b6:c2) via eth0
Jun 13 15:14:23 calculon dhcpd: DHCPINFORM from 10.2.90.168 via 10.2.0.1
Jun 13 15:14:23 calculon dhcpd: JAMF-DHCP change
Jun 13 15:14:23 calculon dhcpd: N Key or encapsulated
Jun 13 15:14:23 calculon dhcpd: 68
Jun 13 15:14:23 calculon dhcpd: DHCPACK to 10.2.90.168 (c8:2a:14:3e:a6:1f) via eth0
Jun 13 15:14:23 calculon dhcpd: DHCPDISCOVER from 00:25:4b:c5:a9:72 via 10.2.0.1: network 10.2.0.0/16: no free leases
Have you guys ever seen this?

Any help you can provide is greatly appreciated.

    Hey @dptech. No expert, but from what I have seen in trying to get our NetSUS working (still in-progress) the /var/appliance/dhcpd.conf file is not actually modified when making changes to the NetSUS webadmin, only the /etc/conf/dchcp.conf file.

    That may be entirely incorrect, but it is what I am seeing when I edit the default NetBoot image. Further, the only part of the configuration file I am seeing actually change is the the path for the booter file, the next server remain static to the original 192.168.0.100 value and the option root path remains static to the default value of:

    option root-path "http://192.168.0.100/NetBoot/NetBootSP0/NetInstall.nbi/NetBoot.dmg";

    Make a change to your NetSUS and let me know if you are seeing the same. Frankly I am not sure if what I am seeing with the static values is a reason that our NetInstall images are working, but the NetBoot images kernel panic'ing and getting vfs_mount failure messages on the client.
