Hello all, With the way work is and the pops are growing looks like i need to start centralising the database. At the moment i have 4 pops around the country and all are feeding from a satellite links, as the company is growing it is becoming very hard to maintain and we are looking to have a central MySQL DB in the UK which feeds the slave machines with the updated info. Each pop will have a live radius / mysql db feeding info back to a master machine in the UK and that would replicate the info down to the slaves on the other pops, this is the wishfull thinking i have :). I have read about Replication with MySQL (One-Way) and radrelay, then i noticed there is rlm_slq_log and radsqlrelay. One thing I must mention there is a lot of LAG on satellite connection looking at approx 650ms and because of BW cost we do rely on proxies which makes BW usage during the day very expensive, so i would like to be able to replicate maybe once a night lets say at midnight being less busy and cheaper. Any one out there with some ideas they can send my way.. Thanks Sarky
