 It may take up to 10 minutes for DNS to update locally; however your ISP DNS server may cache this data for up to 12 hours so you won't see the change immediately. Use the "host" command on the cluster to see if DNS has changed, and "lynx" on the cluster to verify that the site loads: then be patient as DNS changes propagate.
-* The DOCROOT for your directory defaults to no-read access, so you must have an index.html. Directory listings will work on subdirs within the DOCROOT. You can defeat this by running 'chmod g+r $HOME/html'

+* Migrating your CGI scripts from the cluster to the MetaArray? You'll need to pay attention to the filename (only '.cgi' seems to work) and the path to the interpreter. For example, the following script will generate an actual webpage when served from the cluster, but when served from the MetaArray will prompt your browser for a location to save the script itself (first because the path to the interpreter is wrong, and second because the file extension is not recognized by nginx as needing the fastcgi module for its processing).
+  #!/usr/pkg/bin/python3.9
+  # saved as $HOME/html/my_powerful.py
+  import cgi
+  print('Content-Type:text/html')
+  print()
+  print('<!DOCTYPE html>')
+  print('<html lang="en">')
+  print('<head>')
+  print('<title>My powerful script</title>')
+  print('</head>')
+  print('<body>')
+  print('Hello, World!')
+  print('</body>')
+  print('</html>')
+To get this script to behave properly on the MetaArray, change the first line to ''#!/usr/bin/env python3.9'', and rename the file as ''my_powerful.cgi'' .
+===== Simple Personal Server Hosting =====
+ META users can run simple servers using the port that matches their user id. You may run a simple server process on the metaarray as long as it does not circumvent a membership and is a small server "of reasonable or less foot-print". Find more detail and instructions in [[Meta Port Allocation]]
