Binary package “tcpquota” in ubuntu maverick

A dialout/masquerading monitoring package

 TCPQuota monitors and debits users depending on their
 online time (dialout). The program is made for those
 who have a local network with a server that also
 functions as an Internet gateway (among other things).
 .
 The server runs diald, for example, which does the
 actual dial-on-demand, and this package which debits
 each user, whether from the server or from a
 masqueraded host (program includes masquerade code).
 .
 All a user from inside the gateway/firewall has to
 do is run the command 'openhost', and the hostname
 and username is masqueraded and debited according to
 the time they spend calling out.
 .
 When user runs out of money (pre-paid amount), the
 firewall will close the connection for the user and
 it will stay closed until the user deposits more
 credits to the system.
