After Gabber is loaded, the first thing to do is connect and log in to a Jabber server. Figure 1 shows the default Login dialog where information about a user account can be entered.
After entering user information into the required Username, Server and Password fields, click Login to connect and authenticate to the server. The Resource field is required (see below). Unless some unique circumstances are involved, the Port field should equal 5222, Jabber's default port. The priority option is not required to be changed unless desired (see the definition below).
All of the information on the Login dialog can be edited from the Connection Settings dialog, accessible from the Gabber menu.
As Jabber is a distributed architecture like the Internet's email system, the Server field is required. If no other Jabber server is available, the jabber.com server is currently available for public, stable use.
A Resource in Jabber is used to differentiate between different account connections. It can be any value such as "Gabber" or "Home" as long as it is unique for the account. By having unique Resources, a user can login to the same server using the same Jabber account numerous times.
Using priorities, another client can be connected to take lower or higher priority than existing clients. For instance, if Gabber is connected at priority 0 and another Gabber session is initiated at priority 1, the client with priority 0 will receive incoming messages (unless the message is bound specifically to the lower priority client).
