We used to have a RAS before in windows NT where users can dial-in, log in to the network and do anything (even surf the net) as if they were inside the office.
Now that we migrated our whole system to linux, Im not really sure what to setup (or rather what to do) to do the same thing as RAS did before.
Is Windows NT RAS = PPP Dial-in server in Linux ?
Here are what i like to happen :
Users can connect to our workplace by connecting to a modem connected to our logon server as if he is inside our workplace.
Users must be authenticated first by our samba logon server.
Users must be able to surf the internet and download their emails through our proxy server.
Some users will only be allowed via the callback. That means, after a successfull logon to the authenticatio server, they will be dropped and the server will call them to their designated telephone number.
Not all users will be allowed to connect via dial-in, only selected users will be allowed. The server will dropped the user immediately if they are not allowed to use to dial-in.

Are these things possible in linux ? We were able to setup these things in Windows NT, I hope linux can do it also.
Thank you very much in advance.
