Yes. The simplest answer is to use the SUNWfiles backend (see dhcp_modules(5)), and share the files via NFS between servers. The more complex (but much more scalable) way is via NIS+ (on Solaris 10, but not OpenIndiana; NIS+ is dead). Amusingly, the man page still talks about "three" built-in mechanisms but then describes only two. You can also write your own backend to do anything you want; see the "Solaris DHCP Service Developer's Guide:" http://docs.oracle.com/cd/E19253-01/806-6829/806-6829.pdf > Perhaps a shared LDAP backend can be implemented? I'm sure that could be done as well. I don't recall if it was ever done, but I would have expected that it would have been an ARC-required portion of the NIS+ to LDAP transition strategy. I'd expect that Dave Miner at Oracle would know for sure if anyone does. > Secondly, does Sun DHCP support active probing (arp/ping) whether > the IP address it is going to lease is actually available and not > used by some squatter (or a client of another DHCP server), and > logging the result? Yes. And doing so is part of the standard. See dhcpsvc.conf(4) and the ICMP_VERIFY parameter. -- James Carlson 42.703N 71.076W <[email protected]> _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
