You can still impose a password by entering one in the password field.
It??™s possible to allow both invited and uninvited connections at the same time; however,
only one connection can be active at a time (other connection attempts are
denied), and KRfb takes a few seconds to reset when a connection is dropped before
it will accept new ones.
If any invitations are outstanding or if uninvited connections are enabled and the
???Confirm uninvited connections before accepting??? checkbox is selected, the local
user will be prompted with a confirmation dialog before the remote connection is
accepted. This will prevent connections to an unattended KRfb system from succeeding,
so check the configuration if you intend to use KRfb unattended.
Some versions of KRfb have a bug in the XRLE encoding that may prevent
clients from connecting. Specifying hextile encoding on the viewer
command line will work around the problem and enable the connection
to succeed:
green$ vncviewer -preferredencoding hextile blue:0
