Take a look at ports/net/mpich or net/pvm, which are libraries that let you coordinate programs running on different machines. They're mainly meant for parallel computing as opposed to fault tolerant clusters though. > My boss has also suggested that is might be suitable for our DNS > servers as they need to be very high availability, but this would be > of secondary importance. DNS is already "clustered"; just set up multiple slave servers. -- Dan Nelson dnelson@allantgroup.com
