1. Terminal server that does PPP and authenticates via RADIUS This package provides a program named portslave which will use AT commands to answer a modem when it rings. It will then display a login: prompt at which the user can enter a user-name and password. If the user sends PPP data then portslave will run it's own pppd instead and authenticate the user via PAP. When the user-name and password are received they will be verified via a RADIUS server. At the end of the call the accounting data will be written to the RADIUS server. From Debian 3.0r0 APT
