--------------------------------------
Summary: Notify connecting client on unrecognized connection ID
Key: GUACAMOLE-1047
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1047
Project: Guacamole
Issue Type: Improvement
Components: guacd
Affects Versions: 1.1.0
Reporter: Tomer Gabel
When a client starts the handshake with an invalid connection ID (i.e. sends a
{{select}} with an argument prefixed with {{$}}), guacd immediately drops the
connection. Although this is logged on the server said, the client is
completely unaware of what's going on.
Beyond being just plain rude, this makes error reporting and handling difficult
in some cases. The protocol specifically allows an {{error}} command to be sent
by the server during the handshake, which would be very handy in this case;
please expect a pull request addressing this in guacd, hopefully it meets the
contribution guidelines :)
(Incidentally, the handshake implementation in guacamole-common's tunneling
code does not actually handle error commands, expect a separate issue + pull
request to address that.)
