9/15    I've come into possession of about 25 old sparc 5 and 20s
        and i'd like to experiment with them (set up NFS home server, DNS
        RAID, print server, NIS master/slaves, multiple app servers, etc.)
        I'd like to set up my own little network, connected to my office
        network so I can download software and get outside, but not
        interfering with it. Do I need a router or other network
        equipment? Any good quick jumpstart tutorial you can recommend?
           \_ download and install ipf on one of the boxes. And get
              another sbus nic for it. You'll be set to use that as
              your nat/pat gateway. You should be able to score a le0
              (10BT) nic pretty cheap. If you want to try Solaris, try
              2.6 on the 5's. 7 and 8 were pretty slow on the 5's, but
              they should be fine on a 20. You should also consider
              OpenBSD on you SS 5 & 20's. Its a solid OS that will
              really make your systems shine.
        \_ http://docs.sun.com , see the Advanced Installation Guide
           in the Solaris installation docs collection. You can put
           your network of old sparcs on a private network (10.0.0.0 for
           example) behind a box that is running NAT software. This
           way the machines on the network will still be able to see
           the rest of the internet but not vice-versa.
           \_ Make sure that all the netmasks are the same, and that all
              the network card speeds are the same, if they don't all have
              le cards (10Mbit.)  -John
