Alt+Connect 2.5.7/9

Alt+Connect project is a program to manage dialup connections.
Alt+Connect manages dialup connections, allowing a group of networked machines to share a single Internet connection through their server. Custom client software lets users to start or stop their internet connection, and the server (connectd) ensures that the connection remains up only while someones using it.
Features include support for multiple ISPs and links (modems or ISDN channels), connection control lists, ability to record the time a user spends online and charge him for it, and the ability to enable and disable IP forwarding as a machine starts or stops using the Internet.
Whats New in 2.5.0/8 Stable Release:
- A fix has been added which stops connectd from trusting all machines. Without this fix, its possible to login to connectd as any user.
- Connection control lists, bill logging, quotas, etc. are all circumvented, but the wider machine shouldnt be compromised.
- This exploit needs an identd server which doesnt ship as standard with Windows, so you are most at risk if your network has Linux machines under the control of other users; it also needs tcpd support compiled in, so to be vulnerable "[TCPD]" must be in the string returned by "connect ver".
