So on my Irix systems the /var/adm/SYSLOG gets sprayed with those nasty messages. For some reason I haven't seen them on my FreeBSD system... but then it servers a different group, most have static entries in /etc/hosts. Was also thinking FreeBSD's /etc/syslogd.conf may be filtering these messages. I haven't changed it since 2.1.5 or 2.2.0 and have been upgrading via "make world". The solution for Irix was to find the offensive line in popper's source code and bracket it with an "#ifndef sgi .... #endif". The alternative was about 500 entries in /etc/hosts or running my own name server. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
