Cockpit 120

Cockpit is the modern Linux admin interface. We release regularly. Here
are the release notes from versions 119 and 120.

You’ll notice that we’ve dropped the 0.x from the beginning of the
version numbers. This underscores the fact that Cockpit is stable. We’ve
been regularly releasing functionally stable releases for most of the
last year.

Expandable and Filterable Containers and Images
-----------------------------------------------

Lars reworked the Containers section of Cockpit. The various images and
containers are not expandable inline, and it’s also easy to find a
specific image and container by using the filter bar to search for it.

VM Configuration and Monitoring
-------------------------------

Marek worked on a new interface in Cockpit for configuring and
monitoring virtual machines running on the current system. This has the
ability to grow into something like the desktop virt-manager tool.

Unmanaged Network Devices
-------------------------

Cockpit now shows unmanaged network devices in its listing. You can’t
configure them or do much with them, but their presence is acknowledged.
This should make troubleshooting non-standard configurations easier.

Sidebar for Physical Volumes in a Volume Group
----------------------------------------------

Marius added a sidebar that shows up on LVM groups or volumes, that
shows which physical devices are involved.

SSH connections are run in a separate process
---------------------------------------------

When Cockpit connects to an additional server it uses SSH, much like
Ansible or other tools. We now launch a separate cockpit-ssh process for
each outgoing connection to another server.

This lets us isolate the involved code much better, providing security
benefits. But it also makes it possible to insert additional logic when
embedding Cockpit. It’s possible to put in shims to lookup keys,
single-sign-on tokens or keytabs, and so on.

Only connect to remote machines already known to Cockpit
--------------------------------------------------------

When connecting to additional machines via SSH, Cockpit now refuses to
connect to machines it doesn’t have a host key for. This tightens up
security and prevents certain reflection attacks.

Change: https://github.com/cockpit-project/cockpit/pull/5118

Fix bugs preventing Logs page from working in Firefox 49
--------------------------------------------------------

The Logs section of Cockpit failed to function on Firefox 49. This
version includes a fix for that.

Change: https://github.com/cockpit-project/cockpit/pull/5189

Add tooltip describing group name in Roles list
-----------------------------------------------

When configuring local user accounts, one can assign various roles such
as ‘Server Administrator’ to the account. Cockpit now displays the Unix
user group that is involved in the role.
