Of all the gin joints in all the towns in all the world, Matt Braithwaite had to walk into mine and say: > Bill Paul writes: > > > Everything, except you forgot to tell us what version of FreeBSD > > you're using. :) > > > > Since you said 'yppasswdd' rather than 'rpc.yppasswdd' I'm going > > to assume you're using 2.1.5.

I can understand that. I'm a little skiddish around it myself. :) Unfortunately, I did a little mucking about in libc as well, which means that it's not a simple matter to just build the 2.2-current NIS tools on 2.1.x (unless you really, *really* know what you're doing). > holy smokes--- i changed the hostname recently, but did not rebuild > the password maps, because i didn't know about this. i just touched > master.passwd, and rebuilt, and now everything works file.

(Some of the special keys are optional or can be controlled to some extent using command line flags, which are documented.) Ideally, the NIS & NFS book from O'Reilly should talk about this. It's not FreeBSD-specific, but someone forced^H^H^H^H^H^Hrequired to deal with NIS a lot would find himself discovering this sort of thing sooner or later. > it sounds like i need to learn more > about YP internals. :-) You think this is bad, wait until NIS+ comes along. Even I haven't figured out what to do when an NIS+ master server changes hostnames. (Of course I haven't really tried to figure it out yet. I suppose I will once I start writing my on rpc.nisd. :) -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "If you're ever in trouble, go to the CTR.
