Port Forwarding to remote app

[Tushar Jain]

Hi,

My remote app needs access to local USB port. A smart card reader is
connected on the local USB port, and it needs to be accessed by remote app
through guacamole connection. Any ideas on how this can be accomplished? Is
there something like "Port Forwarding" available?

Thanks,
Tushar Jain

Based on what you're trying to do - authenticate with smart cards, which is
essentially certificate-based, or X509, authentication - I would suggest
that you write a custom authentication extension that handles that
mechanism, rather than trying to squeeze the method you're using into the
existing username and password authentication.  While this isn't identical
to SSO authentication, looking at those modules may help you understand how
they "replace" the standard username and password requirements with
something else - in those cases a redirect to another page and processing
of a SSO ticket, in your case the validation and parsing of a certificate
stored on a smart card.

Besides avoiding trying to hack the angularjs pages, it will allow you to
make sure that the authentication happens securely by writing the module in
such a way that the front end (angularjs) and back end (Java application)
are "synchronized" in their conversation for authenticating the user.

The manual has information on the extensions, and, honestly, just looking
at the existing code will probably be as much help as anything.  And, of
course, we are happy to help out here, as well 😁.

Just to add to what Marko already said, you don't want to try to modify the
code in-place - you want to modify the source and then rebuild and redeploy
the web application, asking with any extensions that you use.

Re: How to customize guacamole angular app

[Marko Nikolić]

Hi Ben,

Guacamole supports extension, which are used to add custom features,
integrations etc... to the main application. It is better to use this
method instead of hacking the Guacamole code.

You can find more details on extensions in the docs:
