  • Rudi wrote:
  • Without a password you don't know if the actual viewer is the correct one.
    ID 1-9999
    Using the same repeater (uvnc.com) there is a 1/9999 chance that 2 people use the same ID.
    User can enter a wrong ID, 8483, instead of 8484, and some else viewer is using 8483...
  • Using a password after the encryption has been activated prevent this.
    I would not let my PC alone when a server is waiting on a public repeater
    without password...
  • The password stuff was added after i made several connetions to the wrong server... all people where using the sample ID 543.
  • The profile only has a secured password, all other settings are readable.
    The password in the profile is secured by the standard MS encryption, I
    guess that's based on user and machine.

    When you have your own repeater, it's overkill.
    But as the tool need to serv for several situation, better to add...
Proxy, Use https proxy
cache and anonymizer of your office/home network to Internet via port 443/8080
details http://en.wikipedia.org/wiki/Proxy_server
