My concern was sendmail, so I hacked out the logging for now (ugly). Should go back later and look things over. Didn't like 600K of pertinent logging, but a total log of over 20Mb at one point. Only httpd should listen on the bound IPs for the virtual hosts. Nothing else. Either add inverse or hack the code. ------------------------------------------- Jeff Mountin - System/Network Administrator jeff@mixcom.net MIX Communications Serving the Internet since 1990
