System: Sun 3/160 running SunOS 4.1, *no* YP I had been having problems getting ftp, telnet, finger, etc. to use the nameserver. I received a suggestion to rebuild /usr/lib/libc.so with the inclusion of some .o's from libresolv.a. This worked pretty well; all address resolution was now done through the nameserver. Unfortunately, this makes /etc/hosts completely ignored. Its not *that* intolerable, but the /etc/hosts contained some convenient nicknames for local machines that the resolver doesn't know about. C'est la vie. Worse, however, is the fact that sendmail no longer knows what 'mailhost' is. Outgoing mail is completely dead with regards to non-local sites. Am I doing something wrong, or are there some changes that I need to make in sendmail.cf? thanks, Roger -- "The question of whether a computer can think is no more interesting than the question of whether a submarine can swim" - Edsgar W.

C'est la vie. So add your nicknames to your nameserver database with CNAME records. The easiest place is in your named.local file. I put things there because (1) the info never changes (2) this is the one domain that everyone is an authority for. Purists may groan, as the information really doesn't "belong" there, but it works. ; ; @(#)named.local 1.1 (Berkeley) 86/01/21 ; @ IN SOA host.do.main postmaster.host.do.main ( 901106 ; Serial 3600 ; Refresh 300 ; Retry 3600000 ; Expire 14400 ) ; Minimum IN NS host.do.main 1 IN PTR LOCALHOST. ; ; *** Add Alises Here *** DON'T FORGET THE DOTS! ; mailhost.
