The client becomes "dhcp-0-101.example.com" for IP address 10.0.0.101 in the first DHCP range, and "dhcp-1-101" for IP address 10.0.1.101 in the second range. There's a lot you can do with this, but hat is key. The other useful trick is to set DHCP reservations: Reserve a particular IP address for a particular MAC address when it's plugged into a specific zone, so the same client always gets the same IP addresses in that zone and SSH and SSL keys remain consistent with that client host. > Any suggestions? > > TIA > > -- > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- > - - > - Jason Pyeron PD Inc. http://www.pdinc.us - > - Principal Consultant 10 West 24th Street #100 - > - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - > - - > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- > This message is copyright PD Inc, subject to license 20080407P00. > > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos >
