Thanks for the pointer.

I don't see how this is convoluted. In fact, I would be inclined to claim that it is the defacto method for setting up an internal computational cluster s <---> node1 internet <-F-> FQDN|master <---> w <---> node2 t <---> node3 where swt = switch. > It is not normally desirable to set up a YP/NIS master server on > a machine which is multihomed in the sense of doing NAT or needing > a firewall to separate internal from external, and obvious a > firewall machine running zero or the minimal necessary services is > a lot more secure.... Note that <-F-> actually has at least one firewall. Only people in the apl.washington.edu domain can get to FQDN. I was hoping to use NIS to simplify the propagation of info (eg., passwd, hosts, etc.) from master to the nodes. Propagating the info by hand isn't too bad because I only have five nodes represently. However, I hope to grow an additional 11 nodes. -- Steve _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
