Hi All ,

I may be asking the question to wrong mailing list but still would be greatful if someone could help me out or refer me to the right mailing list. Now the question :

I want to do authentication and accounting for the users on the LAN who use my linux gateway for internet access. My linux box is running redhat 6.2 along with ipchains and masquerading done. 

I have tried using squid for authentication but username/password functionality i.e. authentication but this doen`t work with transparent proxying of squid. I doesn`t know whether PPP over Ethernet can do this  ?  

Could anyone suggest me what to do so that i can authenticate my users on the LAN and also keep and accounting record  for the usage . Their are commercial versions available in the market doing the same but i want some freeware . 

What commercial product do is ..that they have a client exe running on each machine on which user enters his username and password and that exe talks to some port no on the gateway where some sort of modified radius sits which does the user authentication based on the username/password and IP of the user and the  log is maintained for the usage. 


Thanks in Advance

Deepak
