New in this Version
Collax Central: Windows agent and migration between V-Servers
With this version, Collax Central is being prepared for two upcoming products. An agent for Windows should appear shortly. With the Windows agent it will be possible to include Windows servers and desktops in the overview of all servers. In addition, a new function is introduced for the dashboard, which enables virtual machines to be migrated between Collax V servers (project name V-Connect). In Collax Central, for example a VM on a Collax V-Cube can be selected. Via a direct call to the administration interface it can then be moved to a Collax V-Bien.
GUI: copy permalink to clipboard button
This adds a new button to the form controls which allows copying of the current form/detail direct-url to the clipboard. This makes it easy to directly jump to a specific form e.g. via a bookmark.
File: Webaccess - logged in
Previously it was not immediately obvious whether a user was logged in to the webaccess or not. It was only a change in the logout/in icon and the username was visible in the bottom right.
System Management: Saving own URL lists
Own URL lists are available for the webproxy. They offer the option of managing one or more lists of URLs. Up to now, own lists were not saved in the configuration files, but only as a backup item. The ones currently visible in the web interface can now be saved within the configuration files.
A new web terminal is installed with this release. With the web terminal, a direct console call is possible via the administration interface.
Misc: Smbclient and libarchive
With this update, the smbclient is compiled with libarchive 3.4.13 and thus supports different methods of using zip archives.
Misc: Online Documentation - Links to forms
Forms are described in several places in the online documentation. By restructuring the online documentation, forms can now be directly opened from the documentation via a link.
