Hi. I am pretty new to internet and networking PC's and workstations. I am also finding the Sun documentation more confusing than helpful. Could anyone answer some of the following questions. My current problems are: 1. I am not sure if I have specified the correct name and network domain for our 386i. We are running SunOs 4.0.2. Pitt has assigned the machine the name edc3jr.gsph.pitt.edu and the number 130.49.4.223. I am uncertain if I gave the setup the right info though. Currently, there is a nameserver that runs off of the pitt.edu domain. It is called namsrv.gw.pitt.edu I think. Currently there are no other machines(all of which are PC's) in our office group that is ethernetted. This will change over the next few months probably. Currently, I have assigned the name edc3jr and the domain edc3jr.gsph.pitt.edu to the Sun when it initially configures itself. Actually I ran unconfig, put the sun on a network by itself(DESTA box with terminators), rebooted and gave the above name and domain, then added a few lines to the /etc/hosts file (unix.cis.pitt.edu and namsrv.gs.pitt. edu with their full number addresses infront of them.) Then halted, connected the sun to internet and rebooted. Even though this allows me to telnet out and in, it causes some unusual values in /etc/hosts and in snap. Pitt's big unix computer, a Vax 8800(I think) running Ultrix shows long names for all the computers in its hosts file including itself. I.E. unix.cis.pitt.edu, vm1.cis.pitt .edu, etc... Yet my hosts file shows just edc3jr with no gsph.pitt.edu after it. Snap also shows a funny name for the system. For name it has edc3jr.gsph and 4.223 and for domain it shows pitt.edu and 130.49. Is this Right? If not, what should I be entering? 2. Eventually we will hook up other pc to the net. Should they work on some sort of subnet of edc3jr or should they be full internet nodes at the same level as the sun? I.E pc1.gsph.pitt.edu, pc2.gsph.pitt.edu, etc. Am I even making sense here? Eitherway, does this affect the way I name the sun and its domain? 3. Currently, sendmail will only send out some mail but it will not receive mail from outside. What do I need to do to rectify this, create certain files, modify the sendmail.cf file, get a new sendmail from uunet or what? 4. Also, currently to allow users to use tcsh I found that if I cut and paste user's entry from the /etc/yppasswd file into the /etc/passwd file and do a make in /var/yp, that things work and SNAP stays happy. Before when I copied the user over and then deleted him from yppasswd that SNAP ceased to be able to create of modify users thereafter. Am I currently doing things the best way? I know of no chsh that works with yp. 5. Also, is there a newer version of SunOs for the 386i than 4.0.2? Patrick D.
