ISC DHCP on a Solaris 10 Container

[Gordon A. Lang]

I got the dhcpd to run in a Solaris zone by doing the following things:

comment out the #define for ALIAS_NAMES_PERMUTED in includes/cf/sunos5-5.h
uncommented the #define for USE_SOCKETS in includes/site.h
configure;make;make install
add a net interface to the target zone lo0:1 with address of 
10.252.252.11/32
add the following lines to dhcpd.conf:
    server-identifier 10.252.252.11;
    local-address 10.252.252.11;
    subnet 10.252.252.11 netmask 255.255.255.255 {}
modify start script to include the interface name:
    dhcpd -q -cf dhcpd.conf -lf dhcpd.leases lo0:1


I have yet to actually see if it functions properly, but at least it appears 
to work!
