x11vnc's symmetric key [119]encryption ciphers (see the 'UltraVNC DSM
Encryption Plugin' settings panel.)
Here are some features that will appear in the 0.9.6 release:
- * The option [120]-http_oneport enables single-port HTTP connections
+ * Support for [120]VeNCrypt SSL/TLS encrypted connections. It is
+ enabled by default in the [121]-ssl mode. VNC Viewers like
+ vinagre, gvncviewer/gtk-vnc, and the vencrypt package support this
+ encryption mode. It can also be used with the [122]-unixpw option
+ to enable Unix username and password authentication (VeNCrypt's
+ "*Plain" modes.) A similar but older VNC security type "TLSVNC"
+ (used by vino) is supported as well. See the [123]-vencrypt and
+ [124]-tlsvnc options for additional control. The difference
+ between x11vnc's normal -ssl mode and VeNCrypt is that the former
+ wraps the entire VNC connection in SSL (like HTTPS does for HTTP,
+ i.e. it is vncs://) while VeNCrypt switches on the SSL/TLS at a
+ certain point during the VNC handshake.
+ * The "[125]-ssl ANON" option enables Anonymous Diffie-Hellman (ADH)
+ key exchange for x11vnc's normal SSL/TLS operation. Note that
+ Anonymous Diffie-Hellman uses encryption for privacy, but provides
+ no authentication and so is susceptible to Man-In-The-Middle
+ attacks (and so we do not recommend it: we prefer you use "-ssl
+ SAVE", etc. and have the VNC viewer verify the cert.) The "TLSVNC"
+ mode (vino mode) only supports ADH. VeNCrypt mode supports both
+ ADH and regular X509 SSL certificates mode. For them, ADH is
+ enabled by default. See [126]-vencrypt and [127]-tlsvnc for how to
+ * For x11vnc's SSL/TLS modes, one can now specify a Certificate

Red Hat Customer Portal


Welcome to the Fuse 7.0 GA release!

This release continues the evolution of Red Hat Fuse with major component upgrades and expanded range of features for the Apache Karaf, JBoss EAP, and Spring Boot containers. In addition, this release introduces a new approach to creating integrations, Fuse Online, which is hosted on OpenShift Online.

Fuse 7.0 is provided in the form of three different distributions, as follows:

Fuse standalone

The classic distribution of Fuse, supported on multiple operating systems. This distribution is supported for the following container types:

  • Apache Karaf
  • JBoss Enterprise Application Platform (EAP)
  • Spring Boot
Fuse on OpenShift (previously, Fuse Integration Services)

The distribution of Fuse for running integration applications on OpenShift (supported on the Red Hat Enterprise Linux operating system). In this case, the supported container types are provided in the form of docker-formatted container images:

  • Java image (for Spring Boot)
  • Apache Karaf image:
  • JBoss EAP image (new in 7.0)
Fuse Online
The distribution of Fuse that is provided pre-installed on the OpenShift Online Professional tier (and also available for installing on an on-premises OpenShift cluster). In this case, application development is facilitated by a browser based UI, Ignite, and the workflow is simplified to make it accessible to non-expert integrators.

1.3. Uniform technology stack

In Fuse 7.0, the technology stack has been refactored and rationalized to provide a uniform technology stack across all of the supported container types. This uniform technology stack now has the following main components:

  • Apache Camel (application integration)
  • Apache CXF (Web services)
  • AMQ 7 clients with connectivity to an external broker
  • Narayana (transaction manager)
  • Undertow (Web container)

Fuse 7.0 includes several major component upgrades and a large selection of new features. For details, consult the new features sections for each of the Fuse distributions:

Fuse Online, a new offering in Fuse 7.0, provides a web browser interface that lets a business expert integrate two or more different applications or services without writing code. It also provides features that allow the addition of code if it is needed for complex use cases.

Fuse Online runs an integration on OpenShift as a Spring Boot application that uses Apache Camel.

2.1. About the product name

Ignite is Red Hat’s web-based integration platform. Syndesis is the open source project for Ignite.

Ignite runs in two environments:

Product Name

Host Environment

Installation

Fuse Online

OpenShift Online

Red Hat installs and provisions Ignite on Red Hat infrastructure.

Ignite

OpenShift Container Platform

Customer installs and manages.

In user documentation, consider the names Fuse Online and Ignite as interchangeable.

A high level overview of Fuse Online is in Integrating Applications with Ignite.

The main features of Fuse Online in version 7.0 are:

  • Graphical web browser interface that lets business users create and monitor integrations.
  • Connectors that prompt for basic parameters so you can create an integration that connects to:

    • Amazon S3 buckets
    • AMQ and AMQP brokers
    • Dropbox
    • FTP and SFTP servers
