Connection timeout

[Adrian Owen <ad...@eesm.com>]

I have a customer where connection to Linux requires MFA.

How to increase Guacamole connection timeout?


Thanks, Adrian

There is no way to do it except to modify the code used for the
connection and write the necessary code to make the socket wait.
Unfortunately it isn't a matter of just changing a value or constant
somewhere within the code - it takes a decent amount of reworking to
implement it. There is a Jira issue for it, and I've spent some time
recently working on implementing it such that there will be a
connection parameter for it:

https://issues.apache.org/jira/browse/GUACAMOLE-600
https://github.com/apache/guacamole-server/pull/415
https://github.com/apache/guacamole-server/pull/414
https://github.com/apache/guacamole-server/pull/413

That said, I'm not entirely sure that this will actually help you -
the timeouts in Guacamole connecting to a server have more to do with
the amount of time Guacamole tries to establish a connection to the
server, and not so much with how long the authentication process
takes. I would think that a timeout during authentication would be
more determined by the server-side of the connection and how long it
is configured to wait for the user to respond or enter a MFA code
before it gives up and closes the connection.
