A version of the Apache server ships with OS X Server. When you install OS X Server, you should choose to install the Web server. After installing 
WebNative.pkg, Xinet should be ready to use. Point a browser at the machine by entering the hostname or IP address,
 then authenticate as the user 
nativeadmin. Initially, the password will be either the 
Admin password or blank (in which case, nothing needs to be typed in the password field). If the password was blank, be sure after you have authenticated, to change the password for 
nativeadmin to a real password.
 
      A version of the Apache server ships with Linux Red Hat and with SGI Altix. When you install the software, you should choose to install the Web server. When you run the 
installwebnative script, you will be prompted to specify the location where 
Apache was installed. After you supply that information, the script will configure 
Apache and start a browser pointing to Xinet. Authenticate as the user 
nativeadmin with the root password.
