Subject: upgrade, March 6th.

On the morning of Tuesday March 6th, 2001 UVM's main web server,, will be receiving a major upgrade.  There should be no actual
downtime for the web.

The web server will be moving to another UNIX server in the Zoo cluster.
This new server will be faster, but will also have many new features.

For "most" users, this should be a transparent cutover.  All data will be
located in the same place (accessed via DFS, the distributed file system
technology we use), and all pages should continue to function "as is".

If you want to see what your site will look like on the "new" web server,
connect to your site on to test it out. is the
server that will become

Let us know if you have any questions.

For those interested in technical details, read on for more information.

The new web server will be a quad processor Sun Enterprise 420R server,
running the latest version of Apache, with modules for DCE authentication,
SSL for web security, and PHP for dynamic web content.  More information
on each:

o DCE integration.  You will be able to password protect your web pages by
        requiring people to login with their Zoo username and password.
        You won't need to create your own htpasswd files anymore (unless
        you want to, for a generic password protected page), and you
        can restrict access to any listed Zoo user, or group via your
        htaccess file.  The server will also honor UNIX file permission
        bits for secure web data access to restricted users.
        More documentation on this will be coming in the next few weeks.

o SSL support.  We have a new SSL certificate for web security, that will
        work with all pages, and virtual domains on Zoo.  Therefore, it
        will be easy for users to "secure" their web sites.

o PHP version 4 scripting language built in, with support for:
        MySQL database connection support
        Oracle database connection support
        PNG, and JPG library functions.  Can do things like resize
                images "on the fly", and read header information out of
        LDAP integration, for LDAP queries.

The server will continue to offer perl/python/C scripting
options for those wanting to develop their own web applications, not in

Again, let us know if you have any questions.
