Regarding a "quiet" system, would ipfilter, ipnat, ipmon, snort, named, qualify as O.K. processes to be running while the installworld is taking place via SSH in multi-user mode. > Otherwise you will have to disable further logins (see shutdown(8) or > nologin(5) for info on how to do this) and then manually kill most > processes. (Just be careful not to kill your own shell or sshd :-) ) I have already modified the source tree so ipfilter 3.4.17 is the installed version, not 3.14.16 which comes as default. And the named version would remain the same. > and then manually kill most processes. What are some guidelines for which process's to kill example ps -wwaux output follows: USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 1 0.0 0.0 532 0 ??
