You can use the Telnet program to verify that Chat Service is accepting connections and responding to IRC commands. This allows you to determine whether a problem is caused by the service or by the client.
Before using Telnet, verify network connectivity using PING.
To connect to Chat Service using Telnet:
telnet [hostname port#]
USER user_name . . .
NICK nickname
If the service is accepting anonymous IRC client connections, you receive the Chat Service welcome message, the message of the day, and statistical information, such as the number and type of chat users currently connected to the service.
If you receive a Class denied access message from Chat Service, you are a member of a user class whose connections are being denied. Start the Chat Service Manager utility and check the restrictions in the user classes on the server.
If you receive a No more connections message from Chat Service, the server is accepting connections only from authenticated users.
If you can connect to the server and successfully run the User and Nick commands, the problem is not with the server.
If you cannot connect to the server, the problem is probably with the service. Verify the port number and other Chat Service configuration settings.
