Hi,

/usr/local/etc/raddb/radiusd.conf

        ippool main_pool {

                #  range-start,range-stop: The start and end ip
                #  addresses for the ip pool
                range-start = 192.168.1.1
                range-stop = 192.168.3.254

                #  netmask: The network mask used for the ip's
                netmask = 255.255.255.255

forgive my foolish networking but why that netmask? some
method used to try to isolate clients from each other?

That would be the magical mythical network of one mask I was talking 

about at NW. It's valid for any range of IPs and allows communication 

only via the default root.

the correct netmask for that range would be 255.255.252.0
though that would also cover the 192.168.0.0/24 range
too. you need to ensure and take care that you choose

correct aligned regions for IP addresses.

Segmentation fault

what are the permissions of that file and directory? (eg ls -l 

/usr/local/var/log/radius ) and whats the next module in your config file?

otherwise, docs/bugs compile it with debug support etc.
