이건 그냥 참고사항 :

6.1. HPUX requires valid user to run WWW services
On HPUX there must be a valid user and group to run the Apache httpd server. Make sure that the user nobody exists in /etc/passwd and that the group nogroup exists in /etc/group before attempting to start the Apache server. Look in both files and verify that the nobody user and the nogroup group are listed. If the user and group are not listed, please create them.

Example:
bash-2.04$ grep nobody /etc/passwd
nobody:*:30:34::/:
bash-2.04$ grep nogroup /etc/group
nogroup::34:nobody

uucp : sendmail (send mail to a remote user)
