Stupid question

Postby dpuckett » 2007-03-21 16:41

I have things working fine using a repeater. What I have concerns about is that during my testing when I connect to the repeater using 'vncviewer_ssl.exe' I do not have to authenticate myself. What would prevent an attacker from connection to a repeater and simply attempting to connect to random ID:Numbers. Is there a simple way to prevent this?

nothing would prevent it... but at first it is very unlikely that a customer (server) connects to the repeater while someone bad connects to it (with ssl client) and second: the one i am talking about has even has to use the same ID.

Is there any way to restrict which addresses are allowed to connect from a vncviewer_ssl without breaking the server side connection, since they both connect over port 443?

Actually I have my answer. Simply use RC4 Encryption with a new key to ensure end2end encryption should protect againts certain attacks. If someone could post snobs "create your own certificate" util I would feel much more confident in implementing. Thanks

there is a working link again - look into my post...

and an additional encryption is overhead... if you use SC3 there is already ssl encryption, which should do the job...

Thank you snobs. As far as encryption goes. Does using SSL only create a 'gap' at the repeater where both ends are unencrypted? That is how I perceived it where using RC4 is true end2end. Or am I wrong?
