Dynamic Ipaddress using rlm_ippool
I've got the dynmaic ippool handling working. Looking at the source code, it seems to me, that ipaddresses are freed, when an Accounting-Stop record comes along. As those records arrive via udp (true??) some might be lost and the associated addresses will never be freed. Is this true? If so: how can those addresses be set to unused during normal operations? The module ippool is declared experimental. Does anyone have real experience with it?

If it doesn't, it's broken. If so: how can those addresses be set to unused during normal operations? Use a non-broken NAS. Hmm... the module SHOULD handle the case where a stop is lost completely (rare, but possible) and a new start packet comes in for the same port. I haven't looked at the source to see if/how it does this, though. The module ippool is declared experimental. Does anyone have real experience with it? I'm not using it, but a lot of other people are. If there are no objections, it should be declared 'stable' before the next release. Alan DeKok. - List info/subscribe/unsubscribe?

Nevertheless I would like to know, whether there is a chance to monitor how many ips are in use. Does a tool for this already exist?
