Note: The authentication method used is not related to the type of cable modem used.
For example, in San Diego Motorola cable modems are used but the authentication
system is TAS.
Each regional Road Runner cable modem service
uses one of three login authentication systems: TAS, HP, Digital. Refer to the
Regions page to determine which one your service uses.
Toshiba Authentication System (TAS)
Overview
The Toshiba Authentication System uses no password encryption at all. It transmits
your username and password in the clear!
Servers
The authentication servers can be found by doing a DNS lookup for 'tas.'
This will be a CNAME (DNS alias) for a host which handles authentication for your
particular node on your regional Road Runner network.
Protocol
A detailed protocol specification will be made available soon.
Hewlett Packard (HP)
Overview
The Digital authentication system uses Kerberos V for password encryption and
authentication.
Servers
The authentication servers can be found by doing a DNS lookup for 'dce-server.'
This will be a CNAME (DNS alias) for a host which handles authentication for your
particular node on your regional Road Runner network.
Protocol
A detailed protocol specification will be made available soon.
Digital
Overview
The Digital authentication system uses MD5 for password encryption.
Servers
The authentication servers can be found by doing a DNS lookup for 'logon-server.'
This will be a CNAME (DNS alias) for a host which handles authentication for your
particular node on your regional Road Runner network. The port address for the TCP
socket connection is typically 60000 or 60001.
Protocol
