I have gone through many information but none of them tells which file or conf are responsible for 2 independent sql instances.
You use the sql.conf file in /etc/raddb - Make a copy of it, call it... sql-instance2.conf. In sql-instance2.conf, modify the "sql {" line to say "sql sqlinst2 {" Tweak it to fit your second instance. In radiusd.conf, search for the line "$INCLUDE sql.conf" (it should be uncommented). Duplicate the line, change the second one to "$INCLUDE sql-instance2.conf". In the second virtual server, instead of 'sql', use 'sqlinst2'. That should do it. :-) Stefan Paetow Moonshot Industry & Research Liaison Coordinator t: +44 (0)1235 822 125 gpg: 0x3FCE5142 xmpp: stefanp@jabber.dev.ja.net skype: stefan.paetow.janet Lumen House, Library Avenue, Harwell Oxford, Didcot, OX11 0SG jisc.ac.uk Jisc is a registered charity (number 1149740) and a company limited by guarantee which is registered in England under Company No. 5747339, VAT No. GB 197 0632 86.
