4.1) RealPlayer

RealPlayer 4.0 is a real time audio/video transmission/player system. A digital audio/video stream is transmitted from the server over the internet to the destination and played immediately, rather than being stored to disk first and then played.

Each audio/videoclip requires two files: a metafile with extension .ram, and the digital audio/video clip itself, with extension .ra. The .ram file holds one or more lines of ASCII text, each of which references the .ra file to be played when the .ram file is accessed by the browser.

Entries in .ram files have the form:

pnm://machine1.modemswitch.com/rafiles/yourdomain/name-of-clip.ra
or
pnm://machine2.modemswitch.com/rafiles/yourdomain/name-of-clip.ra

or
pnm://machine3.modemswitch.com/rafiles/yourdomain/name-of-clip.ra

Replace 'yourdomain' in the above examples by your domain name, without the top level domain (without the .com or .net ...)

Place your .ram and .ra files in the realaudio subdirectory under your web directory.

.ram files must be uploaded in ASCII mode while .ra files must be uploaded in BINARY mode.

You may then access these files at realaudio/file.ram under your www directory.

4.2) Majordomo

WHAT IS MAJORDOMO?

Majordomo is a program which automates the management of Internet mailing lists. Commands are sent to Majordomo via electronic mail to handle all aspects of list maintainance. Once a list is set up, virtually all operations can be performed remotely, requiring no intervention upon the postmaster of the list site.

_ majordomo - n: a person who speaks, makes arrangements, or takes charge for another. From latin "major domus" - "master of the house".

Majordomo controls a list of addresses for some mail transport system (like sendmail or smail) to handle. Majordomo itself performs no mail delivery (though it has scripts to format and archive messages).

Here's a short list of some of the features of Majordomo:

  • supports various types of lists, including moderated ones.
  • List options can be set easily through a configuration file, editable remotely.
  • Supports archival and remote retrieval of messages.
  • Supports digests.

    4.2.1) Creating a new list

    Use the order form to activate/order your new list.

    4.2.2) Subscribing

    To subscribe, send the message

    subscribe your-list

    to majordomo@yourdomain.com

    4.2.3) Unsubscribing

    To unsubscribe, send the message

    unsubscribe your-list

    to majordomo@yourdomain.com

    4.2.4) Posting

    Messages sent to your-list@your-domain.com will be posted to the entire list.

    4.2.5) Master subscribing

    approve pswd subscribe your-list new-subscriber@somewhere.com

    This will subscribe yourself to the list or anyone else you wished. Pswd is your password. Try this out since we haven't yet subscribed you to your own list.

    4.2.6) Master unsubscribing

    approve pswd unsubscribe your-list former-subscriber@somewhere.com

    This unsubscribes the person whose e-mail address is given.

    4.2.7) Creating digests

    To create digests, ask us to activate the digest feature for your list.

    How do I control how often they are created?

    You could use cron to create periodic digest with a command like the following:

    echo mkdigest [digest-name] [digest-password] | mail majordomo@...

    This will force a digest to be created. Or you can set the max size in the digest list config file down low, and force automatic generation.

    This would mean that you would be changing the text:

    maxlength = 40000

    in the list configuration for the digest. Send 'config your-list pswd' to majordomo to get the configuration which you can edit and send back.

    You can combine the two methods, for example to send out at least one digest per day but more if that one would be over a certain size.

    4.2.8) Answers To Common Questions

      4.2.8.1) How do I change my info message?

      Send to listproc or majordomo:

      newinfo mailing-list-name pswd

      Blah, blah, blah.

      This will add a welcome to the message everyone sees when they subscribe. It will also be used if a customer requests info on a list. Note the blank line between the newinfo command and 'Blah, blah, blah'. Also note that you can not include any other commands with this command. Of course, the info message can be many lines.

      4.2.8.2) How do I change my password?

      passwd mailing-list-name old-password new-password

      Will change your master password from the old-password to the new-password.

      4.2.8.3) How do I get a list of the subscribers?

      approve pswd who mailing-list-name

      4.2.8.4) How do I post a message to my moderated list?

      Posting a message with the following text at the beginning will work.

      Approved: passwd
      From: list@your-domain.com
      To: list-l@your-domain.com
      Subject: Whatever you please

      Message begins here. (Note the blank space -- the first blank line in the message.)

      4.2.8.5) How do I change the reply-to field?

      Send the command config mailing-list-name pswd to get a copy of your self-documenting configuration file.

      You will find the area that contains the reply-to field.

      Update this field and then send the command newconfig mailing-list-name pswd followed by your new configuration file.

    4.2.9) Helpful mailing list

    If you need help, there is a mailing list majordomo-users@greatcircle.com, which is frequented by lots of users of Majordomo.
