I have a question about the loopback interface found on our Sun workstations. Our problem is that when we do a netstat -a, a bunch of the following connections are formed (ie. dozens): Active connections (including servers) Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp 0 0 loopback.2703 loopback.sunrpc TIME_WAIT tcp 0 0 loopback.2702 loopback.sunrpc TIME_WAIT tcp 0 0 loopback.2701 loopback.sunrpc TIME_WAIT . . . These go away after awhile, but we can't figure out why they should be there in the first place. Here is our entry for loopback: 127.0.0.1 loopback lb localhost loghost datehost Here's some more funny stuff. One another Sun we have an entry of: 127.0.0.1 loghost me loopback localhost and there's no loopback connections created during a netstat -a! What could be the difference? We are running Sun OS 3.3 on our 'problem' Sun, and 3.4 on our 'good' Sun. Thanks in advance. --mike -- Mike Tankenson Telos/Jet Propulsion Laboratory - NASA 4800 Oak Grove Drive, Pasadena, CA. 91109 (818) 354-1447 Uucp: seismo!cit-vax!jplpro!mike Arpa: jplpro!mike@cit-vax.ARPA -or- mike@jplpro.JPL.NASA.GOV

Netstat will report the first name on the line in the host table (actually, the "official name" as returned by gethostbyaddr() which will be the first name after the numeric address. See 'man gethostent' for details.) You can change it if you like by just reordering the names and rebuilding the yellow pages (cd /etc/yp;make). -Barry Shein, Boston University
