This happened to us. The problem was with SGI's bootparam responding to a net "boot me" request without making a clean check with it's bootptab file. In our case we had an empty bootptab file (no disk less nodes to be booted) and it was confusing the suns on the same ethernet. Our solution, which won't work for you was to turn off the bootp* inet port listeners so it couldn't respond. > >I've tried ftping sgi.com:sgi/src/rpc.bootparamd.Z and installing >that, but it doesn't seem to have helped. Uno's /etc/bootparams only >has due listed, and /usr/etc/bootptab only has due after the "%%". I remember seeing some solution coming accross this news group a while ago that patched that faulty bootp*d program(s). I'm sure SGI knows about this problem and has a solution. I just don't know whether it's include in 3.2[.0]; the problem occurred with 3.1 and I haven't check to see if it's fixed. ** SGI folks: let me know if this is fixed so I can leave the /etc/services file in standard setup. > David Keegel (djk@cs.mu.OZ.AU) > Enjoy, Bernie Duffy Systems Programmer II | Bitnet : BERNIE@UMBC2 Academic Computing - L005e | Internet : BERNIE@UMBC2.UMBC.EDU Univ. of Maryland Baltimore County | UUCP : ...!uunet!umbc3!bernie Baltimore, MD 21228 (U.S.A.) | W: (301) 455-3231 H: (301) 744-2954
