Hosted on Comm-dev

Connecting to Services


Generic Setup

You need to register an account with the server first, most clients can handle this. (See setup for Pidgin) The server hostname to use is The server also supports SSL encryption. Chat rooms are hosted at

Setup for Pidgin

Pidgin is an open-source, cross platform program that handles multiple chat protocols, and is present on all the Lab machines.

Create/Add Account
  • To set up an account, when you open the application click Accounts > Manage Accounts.
  • Then click "Add...", and change the protocol to XMPP.
  • Enter your desired username and password, and for domain, enter
  • Resource is optional - it is a name for your current method of connection, such as "Pidgin"... anything is fine here, see this page for more detailed information
  • Uncheck the box labeled "Store password" for security purposes. Pidgin/libpurple stores your password as plaintext, so it may be viewable by others.
  • Finally, if you are making a new account, be sure to check "Create this new account on the server" at the bottom... this will register you with the XMPP server. Otherwise, the account will be set up in Pidgin but unable to connect to the server.
Adding a Friend

Adding a friend is easy, click Buddies > Add Buddy... Enter the friend's username in the username field, but be sure to add! This is important, otherwise the user will not be able to be found. So for example, is a valid complete username. In addition, you may optionally add an alias in the following entry box to specify a real, or alternate name for the user, which will instead appear on your buddy list, and in the chat window.

Creating/Joining a Chat Room

Creating and joining a chat room uses the same method, as a chat room is created if the name does not exist. Simply click Buddies > Join a Chat..., enter the room name, and leave the server as the default You may optionally change your handle (name), and set a password for the session in the last two boxes.

The most common chat room is "cosi", although others spring up from time to time.


To connect to the mumble server, you'll need the Mumble client (this can be retrieved from your local package manager, or acquired from their page here). On the first running of the software, it will prompt you to configure your audio devices, which is beyond the scope of this guide. To add the COSI server, click Connect, Add New... on the next window. Enter the following data:

Label: A name for these server settings to be saved by (your choice). Address: ( will also work). Port: 64738 Username: The name you want to be identified by

There is no password, so that can be left blank.
