I am a relative newcomer to the Unix/Sun world, in fact, this is why I am writing. My first task in a new job was to reconfigure a Sun386i to use myself. I loaded the OS, the easy part, and the machine seemed to have its own ideas about how it should be configured. I chose to set up the machine as a master server because there were other 386i's on the net but they weren't really speaking yp. As a master server on the net, I had all kinds of problems getting the machine to talk to other machines. Since my job is campus networking, I had to find some way around this. The only solution I've found so far is to kill of the yp specific processes and to load a large /etc/host file from another machine onto this machine. This seems to work well except for the fact that I still don't have name service outside of my domain. I have a resolv.conf file that points to the nameservers in my domain and nslookup is working fine. Ftp and telnet are another story. Mail is my second problem. As it sits, the machine will deliver mail to the outside world but will not deliver mail to the user accounts within. Mail -v from other machines is delivered to the machine and then returned. sendmail is running with the sendmail.subsidiary.cf config file, I think it should be running with the .main.cf file and that the mailhost should be itself, but when I do this it won't even sendmail out - something about getting the domains confused - the yp domain and the internet. Any suggestions short of trading the machine in on a sparc station would be welcome. Should I be running in.named? should I tinker with the net.conf file - especially the PNP variable? etc...

Since my mail bounced and others may be interested in knowing about this document, sunspots now gets it. LEW I have a SUN 386i setup as a master YP server on a standalone network with PC clients running PC-NFS. Since I am not connected to the rest of the world yet (supposed to be in two weeks), I don't think I'm qualified to help you much with the specifics of your problem(s). However, I have one piece of information you may not know of that will be useful later on if not with your current problem(s). Sun has a document called the "Sun386i Administration Cookbook" that details the differences between the 386i and Sun's other machines. It has specific chapters setting up a 386i in different network environments, multiple domains, etc. I feel this document should have been part of the standard documentation for a 386i since it answered many questions I had about the machine when I first obtained it. All of the chapters from this document were also published in Sun's Software Technical Bulletins (I think they were the Nov. and Dec. 1989 and Jan. 1990 issues). Hope this helps some, Larry E.
