Cockpit 265
Cockpit is the modern Linux admin interface. We release regularly.
Here are the release notes from Cockpit 265 and cockpit-machines 264:
Animate new rows in lists
When new items appear on a page, they are highlighted for a short while to make it easier to notice them.
Support for X-Forwarded-For
When run in a configuration involving a reverse proxy server, Cockpit can now report the client IP address as provided to it by the proxy server, rather than using the IP of the proxy server itself. This impacts what appears in system login logs, for example, and may have an impact on authentication, depending on which pam modules are in use.
Support for this feature must be explicitly enabled via the new ForwardedForHeader option in the configuration file.
Manifest overrides in /etc and ~/.config directories
Manifest override files are a way to customize or hide a Cockpit page’s menu entries. Until now these needed to be put next to the manifest.json which they modify, for example /usr/share/cockpit/systemd/override.json. However, /usr/share/ is package manager territory, and admins should not (and in some cases cannot) write files there. With this Cockpit version, these overrides can now be placed into /etc/cockpit/systemd.override.json for global customizations, or ~/.config/cockpit/systemd.override.json for user-specific ones.
Crypto policies support
Cockpit now has basic support for displaying and changing a subset of crypto policies (default, future, legacy). The current configured crypto policy is shown in the “Configuration” card.
Crypto policy changes can be applied immediately or later. When “Apply only” is selected, the Health card shows that a reboot is required to fully apply the changed crypto policy.
Metrics: Show busiest CPU core
On multi-core systems, the Metrics page now shows an additional usage bar for the CPU core with the highest usage. This points out bottlenecks and performance problems which happen because only a few cores (or even a single one) get fully used, while many others are mostly idle. In that case, the average CPU usage will be low.
Machines: Disk serial number
A disk identifier can now be specified for attached disks. This is the identifier that appears for the disk in /dev/disk/by-id on Linux systems and might be useful for multipath storage setups. It may also be useful with proprietary software which is licensed to specific disk serial numbers (which is sometimes seen on Windows).
