Thank you James Carlson and Roy Sebastien for clearing this up for me. I'll make the changes and continue with my testing.

I have a theory. Your IP address is in /etc/hosts, but not in /etc/inet/ipnodes. The lookup order in the nsswitch is ipnodes first, then hosts. In nsswitch.conf, you probably have something like: hosts: files dns ipnodes: files dns In which case, the system looks things up in /etc/inet/ipnodes, then dns, then in /etc/hosts. This is broken system architecture which was recently fixed in Nevada. For now, a workaround is to populate your addresses in both /etc/inet/ipnodes and /etc/hosts. If you upgrade your systems to a recent OpenSolaris Nevada build, you can see that /etc/inet/ipnodes is just a symbolic link to /etc/inet/hosts. See the following CR fixed in snv_47 for more information on this problem: 6219146 /etc/inet/hosts and /etc/inet/ipnodes need to be the same file http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6219146 -Seb _______________________________________________ networking-discuss mailing list [email protected]
