FAQ for z.cs.utexas.edu

  1. What is z.cs.utexas.edu?

    Z is an experimental web server maintained by CS staff. It operates independently from the production CS server on www.cs.utexas.edu. It sometimes appears under the alternate name zweb.cs.utexas.edu.

  2. Who can use it?

    Anyone with a current CS Unix account.

  3. Why another web server?

    The extra features provided by this server have long ago been migrated to the CS production web server. This server should be considered deprecated, and is supported only for migration and redirection purposes.

  4. Where are the http log files on z?


  5. How do I use the MySQL server on z?

    Request a MySQL account here. Specify a database name which you want to create. Your MySQL login name will be the same as your CS Unix login name.

  6. Can I have a shell account on z?

    No. Z has no non-staff shell accounts, similar to the CS production web server.

  7. When can't I access the MySQL server on port 3306/tcp from hosts outside the CS department?

    The sole purpose of the MySQL server is to support http applications on z. As such, you should be able to administer MySQL from your http application. (This is basically a security policy -- I don't want to make a MySQL server visible to the endless stream of portscans, so 3306/tcp is blocked at the router).

  8. But that's unreasonable. Some MySQL operations are are only possible (or at least are much more easily done) with direct access to the server.

    All of the utilities in the MySQL distribution are available, and you can use them from any CS host. These tools should provide all the necessary MySQL access which one might need.

  9. How do I change my MySQL password?

    Connect with the mysql client and use set password, i.e.

       mysql -h z -p -u LOGIN

    where LOGIN is your CS Unix (and MySQL) login name. Then at the mysql prompt:

       mysql> set password = password('NEW-PASSWORD');

    where NEW-PASSWORD is your new MySQL password. It is not advisable to use your Unix password as a MySQL password.

  10. Why is the server named "z"?

    Long, cute hostnames are overrated. :)
