I’m running SmartOS at home, and I have a Raspberry PI running dnsmasq as my
DHCP and DNS server. My DHCP-configured computers will give their hostname back
to dnsmasq so that I can look up the computer by name instead of IP address. I
can’t seem to make that work for an Ubuntu LX zone that I create in SmartOS.
For example, here’s the JSON for a Ubuntu 14.04 LTS zone that I created:
{
"brand": "lx",
"kernel_version": "3.13.0",
"dataset_uuid": "52be84d0-6b06-11e5-a4c0-9f0c52fa368a",
"resolvers": ["192.168.1.2","8.8.8.8", "8.8.4.4"],
"max_physical_memory": 4096,
"autoboot": true,
"alias": "owncloud",
"hostname": "owncloud",
"zonename": "owncloud",
"nics": [
{
"nic_tag": "admin",
"ip": "dhcp",
"primary": true
}
]
}
The DHCP IP address assigned is 192.168.1.160. If I do a “dig -x
192.168.1.160”, I won’t get the hostname that I’ve given to this zone. In fact,
I won’t get anything in the form of a name. The LX zone, though, knows its
hostname, and I’ve verified that it is correct.
Is there a way to get the hostname registered with dnsmasq for a LX zone? It
happens automatically for Linux systems that are running Ubuntu, but not for LX
Ubuntu images.
Thanks,
John
