[OmniOS-discuss] ISC-DHCPD in a zone

[Michael Mounteney]

I'm sure this has been done before but I can't find anything in my
archive of this list.  In a zone, isc-dhcpd is failing on start because
it can't obtain the details of an interface.

Zone# ifconfig -a
lo0:2: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 
e1000g1:2: flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> mtu 1500 index 2 inet 192.168.1.2 netmask ffffff00 broadcast
192.168.1.255 lo0:2: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1 inet6 ::1/128 

According to various sources, one can specify interfaces on the command line to restrict dhcpd:

/usr/sbin/dhcpd -cf /etc/dhcpd.conf -lf /var/db/dhcpd.leases -p 67 -s 192.168.1.2 e1000g1
binding to user-specified port 67

Specifying e1000g1:2 makes no difference.

Obviously normally isc-dhcpd is run via a service, but the above command is what is eventually execed and it fails with the above message in the log.

Really I don't care about that lo0:2 interface.  Is it the unconfigured ipv6 ?  If I could get rid of that, it would solve my problem.

Any help ?  Either restrict isc-dhcpd or eliminate the interface.
