Hi all,

has anybody ever heard of a telnet-proxy? Checkpoints Firewall-1 offers this kind of functionality:

You connect to the firewall on port 23, firewall asks for authentification and a hostname and afterwards you get a transparent telnet session to the named host, without any intererence by the firewall.

Is something like that available as open source software?

Thanks a lot,

Martin

Well, the checkpoint-function is not a realy proxy, but a kind of userauthentification. In fact the firewall creates a dynamic rule for this service after a positiv authentication. So, if you run ipchains you can create a user with a script integrated in the login-shell. If you have to consider dynamic ip-adresses you have to use perl and the project becomes a little bit tricky ;-) But perhaps the tcpbroker-tool fit into your requisition.
