dig and nslookup use THEIR OWN resolver routines, =not= the 'standard library' routines. Something that fouls the library routines will not affect dig and nslookup. Given this is Solaris, check /etc/nis.switch (may not be the exactly correct name, but close -- I haven't used Solaris in a decade). check both the file content, and permissions. You may have to run truss on ping to see what it's getting wrong. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
