idea/rfc: device screen in cockpit
by Martin Polednik 03 Dec '16

03 Dec '16

Hello, I have an idea for cockpit, but before thinking it further, I'm interested in hearing your opinions. I am oVirt developer mostly dealing with system stuff and this is something that could be useful in virtualization while also providing utility for administrators using cockpit. The idea is about new tab/plugin (not sure of the terminology) called 'devices', that would allow access to (hardware) devices as exposed by sysfs. The interface could be similar to 'Services' tab/plugin, showing a list of device names created from their physical location, similarly to libvirt's nodedev-list. After clicking on the name, new screen would be presented, showing additional information such as * physical address, * driver in use, * special capabilities (SR-IOV numvfs and totalvfs, NPIV max_vports, vports), * iommu group (possibly clickable to reveal all devices in given group), * vendor, vendor id, product, product id. Additionally, it makes sense to allow some basic operations: * unbinding from host driver, binding it to specific one (useful for local vfio-pci testing), * reattaching it back (one use case is that oVirt does not reattach devices automatically due to possible issues, needs user intervention), * setting numvfs, vports, * ... ? Do you find ideas above reasonable for cockpit? It is mostly in idea phase, and builds on development and requirements of oVirt. I personally believe that this could be useful for broader audience. Thanks, mpolednik

"Rebase and merge" button on github
by Marius Vollmer 03 Oct '16

03 Oct '16

Hi, Github now has a "rebase and merge" button which does exactly what we have been doing manually so far. I think we can just use it. Differences compared to our old way are: - We don't get any opportunity to add the "Reviewed-By" line, but we can use the "Commit" field instead that is shown by "git log --format=full" and also by Github. - Github now says "Merged" instead of "Closed". - It's less work. I have closed two PRs with that button: #5079 and #5084. I'll update our Workflow document, OK?

Cockpit 118
by Stef Walter 08 Sep '16

08 Sep '16

http://cockpit-project.org/blog/cockpit-118.html Cockpit is the modern Linux admin interface There's usually a release every week, but this time around we were delinquent and it's been nearly a month. 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. And over the last few months we've worked hard on identifying stable javascript APIs and protocols for various Cockpit components to consume. We'll be itemizing these stability guarantees in the documentation shortly. Timer jobs in systemd --------------------- Harish did great work during Google Summer of Code to add support for systemd timers. Timers let users schedule tasks similar to cron jobs. Timers are now listed, and dialogs for defining jobs and their recurring patterns are now included in Cockpit. Blog post: https://medium.com/@harishanand95/gsoc-creating-timers-in-cockpit-f4034c79d… Screenshot: http://cockpit-project.org/blog/images/cockpit-timers.png Change: https://github.com/cockpit-project/cockpit/pull/4645 Two factor authentication on login screen ----------------------------------------- Peter pulled off a major change to have full PAM conversations supported on the Cockpit login screen. This means you can use two factor authentication dongles or Yubikeys in your login workflow in Cockpit. In addition, for the next release Stef worked on allowing the user to change expired passwords while logging in, similar to how they would on the console. Demo: https://www.youtube.com/watch?v=gXsOt6zgBs4 Change: https://github.com/cockpit-project/cockpit/pull/4827 Use Webpack to build the Cockpit interface ------------------------------------------ Most of Cockpit is written in javascript and runs in the browser. This code is now built with Webpack. It's bundled into single page application bundles per Cockpit component. Among other things, this makes hacking on Cockpit much easier. Documentation: https://github.com/cockpit-project/cockpit/blob/master/HACKING.md Make Docker resource limits work on Debian ------------------------------------------ The container resource usage graphs and resource limit dialogs now work properly on Debian. Stef adapted the code to account for the different CGroup layout than Docker uses on Debian. In addition the SSH key listing code now works on Debian. Change: https://github.com/cockpit-project/cockpit/pull/4845 Configure Cockpit URLs with an HTTP prefix ------------------------------------------ The HTTP URLs that Cockpit uses can now have a (mostly) arbitrary prefix in their path. This is useful in scenarios where Cockpit is proxied by another application or management console. Use the UrlRoot option in cockpit.conf Documentation: http://cockpit-project.org/guide/latest/cockpit.conf.5.html Change: https://github.com/cockpit-project/cockpit/pull/4937 Components can require a minimum Cockpit version ------------------------------------------------ Cockpit is built from various components that are independently installable and composable. Various components provide network configuration, or storage, or container functionality. These components can now indicate which part of the base javascript and base cockpit-bridge they require in order to function. This is configured in the package manifest Documentation: http://cockpit-project.org/guide/latest/packages.html#package-manifest Change: https://github.com/cockpit-project/cockpit/pull/4964 Get it ------ You can get Cockpit here: http://cockpit-project.org/running.html Cockpit 118 is available in Fedora 25: https://bodhi.fedoraproject.org/updates/cockpit-118-1.fc25 Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/118 Take care, Stef

Change in Cockpit version numbers
by Stef Walter 08 Sep '16

08 Sep '16

Yesterday several of us (roughly the top contributors [1] to Cockpit) discussed removing the '0.x' from the Cockpit version number. The plan is from here on out to just go with integer versions, starting with version '118' following version '0.117'. Cockpit releases weekly. Some versions of Linux distributions closely track that weekly release. Other choose particular releases to include, based on features and other criteria. Cockpit now has a stable javascript API and file layout for components [2], as well as backwards compatible transport protocol. I hope to post more documentation about these guarantees soon. Cheers, Stef [1] https://github.com/cockpit-project/cockpit/graphs/contributors?from=2016-01… [2] http://cockpit-project.org/guide/latest/development.html

Problem adding host
by Fuji San 01 Sep '16

01 Sep '16

Hello, I'm having trouble adding a host to cockpit. It was already listed in cockpit but then I reinstalled fedora on it, removed the host from cockpit and now I get the following message when I try to add it again: Incorrect Host Key The key of *myhost.mydomain* does not match the key previously in use. Unless this machine was recently replaced, it is likely that someone is trying to attack your connection to this machine. How can I solve this? Thank you. F.
