I know this has been hashed here before... But I think there is a different twist to this... I'm looking for IP management tools that also tie into DNS and RADIUS or LDAP. We have some home-grown products that have been written for our specific requirements but it's become a chore to maintain. What we are looking for is this... IP allocation and accounting. DNS tie-in for Dynamic DNS functionality Ability to assign permanent leases from a common interface (DHCP server back-end tie-in) We perform a MAC-based authorization for DHCP and would like to keep that functionality We would also like to continue this as we implement 802.1x in the future. Does anyone have some insight into what tools to look at... Please respond off-list - if there is enough interest I will summarize to the group... -- Rich Sena - ras@thick.net ThickNET Consulting "On the way to understanding; you understand, and forget."
