Any update on a bridge/agent for CentOS/RHEL 6.7 Server monitoring & support
by Donald DAvanzo 21 Jan '16

21 Jan '16

Hello everyone Just wanted to see if anyone has made any lead way with supporting CentOS/RHEL 6.7 via a bridge / agent so these os releases can be brought into cockpit for resource / servcice monitoring I know about 8 or 9 months ago this was talked about but not sure if anyone has taken it upon themselves to come up with a solution yet or if there is one in the works. Let me know as we still have a few hundred 6.7 clients hosted in our cloud and it will take a very long time to safely migrate them if even possible to a 7.x release. Regards, Donald R.

Read-only mode?
by Duncan.Innes＠rbs.com 03 Nov '15

03 Nov '15

Hi, Is there a read-only mode with the Cockpit interface to allow system details to be gathered, but not altered? Our use for Cockpit would like to see a read-only mode and perhaps a couple of different read/write mode access levels (middleware team can only restart httpd & JBoss etc). I'm looking at this from the perspective of seeing the Foreman-cockpit plugin this week. This plugin seems to provide unfettered access for any Foreman user. Is this where "Deep Integration" will come in? Also wondering if it's possible to write bespoke modules for Cockpit to allow us to report our specific application stats back via the Cockpit service. The docs explain how to embed cockpit and use cockpit components, but not how to integrate our own modules into cockpit (to my non-developer eyes).

Cockpit 0.82
by Stef Walter 29 Oct '15

29 Oct '15

This is a summary of the Cockpit weekly release. This week it was 0.82 Distributed Tests ----------------- In Cockpit we run thousands of integration tests per day against pull requests and git master. Each test brings up up Cockpit in a full operating system VM, and hammers on it in some way. Without these tests it's impossible to validate that Cockpit actually works. Last week, the server doing this testing work broke down. We've been working over the last week to fix that. And it's taken most of our time. But we've done more, instead of just putting this on another server, we've worked to make these integration tests run in a distributed manner across several machines each doing a part of the tests. The tests are staged via privileged containers, and run in libvirt VMs. There's still a lot of flakey test failures, but those are being sorted out step by step. Docs: https://github.com/cockpit-project/cockpit/blob/master/test/README More: https://lists.fedorahosted.org/pipermail/cockpit-devel/2015-October/000364.… Certificate Chains ------------------ Cockpit has supported using certificate chains for its cockpit-ws component, but only when the underying GLib (2.44+) supported it. In this release we start to support running TLS with proper certificate chains even on older GLib versions: http://cockpit-project.org/guide/0.82/https.html#https-certificates Next ---- There's lots of other work in progress. You can see it here in the Design and Implementation columns: https://github.com/cockpit-project/cockpit/wiki/Features https://github.com/cockpit-project/cockpit/pulls https://trello.com/b/mtBhMA1l/cockpit Get it ------ You can get Cockpit 0.82 in Fedora 23 or Fedora Rawhide: https://bodhi.fedoraproject.org/updates/FEDORA-2015-273bc74c11 Or via COPR for CentOS, RHEL, and earlier versions of Fedora: https://copr.fedoraproject.org/coprs/sgallagh/cockpit-preview/ Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/0.82 Cheers, Stef

Distributed Cockpit Integration Tests
by Stef Walter 29 Oct '15

29 Oct '15

In Cockpit we run thousands of integration tests per day against pull requests and git master. Each test brings up up Cockpit in a full operating system VM, and hammers on it in some way. Without these tests it's impossible to validate that Cockpit works. Last week, the server doing this testing work broke down. We've been working over the last week to fix that. But we've done more, instead of just putting this on another server, we've worked to make these integration tests run in a distributed manner. As a developer using the new distributed tests is a bit different, and the documentation has been updated: https://github.com/cockpit-project/cockpit/blob/master/test/README Other Operating Systems ----------------------- Previously we were limited to running the tests on Fedora 22 and RHEL 7.1 for each pull request. One of the reasons was that the server was simply maxed out much of the time. By distributing the integration tests, we can open the floor to testing on further operating systems, and having multiple cases of the tests running in parallel for each pull request. Obviously this is not the only factor in running integration tests against say Debian ... but it was certainly a big blocker in the past. If dedicating time toward Cockpit's integration tests running on another OS is something that interests you, don't hesitate to post here on this list or in the #cockpit channel on FreeNode. Cheers, Stef

Cockpit SSO with kerberos not working
by Fuji San 23 Oct '15

23 Oct '15

The step described here (http://cockpit-project.org/guide/latest/sso.html) are exactly the steps I do to configure FreeIPA to SSO with kerberos. If I create a kerberos ticket with "kinit admin", when I go to http://ipasrv/ipa/ui with firefox from my desktop (ipa client), I am logged in without username/password. But when I go to http://ipasrv:9090 with firefox (cockpit is installed on the ipa server), cockpit asks me for a username and password. And I log in as root. On the ipa server, I can run $ getent passwd smith(a)example.com smith:*:1002:1025:John Smith:/home/smith:/bin/bash $ host -t SRV _kerberos._udp.example.com _kerberos._udp.example.com has SRV record 0 100 88 zaira.example.com. On my desktop, firefox is configured like this: network.negotiate-auth.trusted-uris user set string .example.com So I must be missing something. Regards, Fuji

Cockpit 0.81
by Stef Walter 22 Oct '15

22 Oct '15

This is a summary of the Cockpit weekly release. This week it was 0.81 NTP servers ----------- Cockpit now allows configuration of which NTP servers are used for time syncing. This configuration is possible when timesyncd is being used as the NTP service. Demo: http://www.youtube.com/watch?v=3DRmzt1L4ANgo Card: https://trello.com/c/sjoetDb0/140-0-81-time-sync-configuration Network switch regression ------------------------- There was a regression in Cockpit 0.78 where certain on/off switches in the networking configuration stopped working. This has now been fixed. Delete Openshift routes and deployment configs ---------------------------------------------- In the Kubernetes cluster dashboard, it's now possible to delete Openshift style routes and deployment configs. Next ---- Cockpit has refactored its Kubernetes container terminal widget for use by other projects. It's been integrated into the Openshift Web Console for starters. This widget will be used by Cockpit shortly. Widget: https://github.com/kubernetes-ui/container-terminal/ Demo: https://www.youtube.com/watch?v=3DSMxVQBD3Kho There's lots of other work in progress. You can see it here in the Design and Implementation columns: https://github.com/cockpit-project/cockpit/wiki/Features https://github.com/cockpit-project/cockpit/pulls https://trello.com/b/mtBhMA1l/cockpit Get it ------ You can get Cockpit 0.81 in Fedora 23 or Fedora Rawhide: https://bodhi.fedoraproject.org/updates/FEDORA-2015-c3b74dffee Or via COPR for CentOS, RHEL, and earlier versions of Fedora: https://copr.fedoraproject.org/coprs/sgallagh/cockpit-preview/ Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/0.81 Cheers, Stef

Cannot add a host. Says "Cannot forward login credentials".
by Fuji San 22 Oct '15

22 Oct '15

I installed cockpit 0.67-2.fc22 on an ipa server and added several servers from the dahsboard as you can see here: http://i.imgur.com/vca19wS.png But there is one server that keeps annoying me (as you can see here: http://i.imgur.com/3J7AHQY.png) It says "Cannot forward login credentials". I checked in /var/log/messages and found this: Oct 22 10:10:02 zaira2 cockpit-ws: adina.xxx: ssh-ed25519 host key for server is not known: 8f:55:e3:ee:90:f3:30:11:43:3b:99:97:c5:9c:8a:0f but then I found the same message for all the other servers I succeeded to add to the dashboard: Oct 22 09:47:51 zaira2 cockpit-ws: zaira.xxx: ssh-ed25519 host key for server is not known: f5:d7:67:d1:7b:db:d3:b0:54:4d:b7:0e:b9:38:da:a7 Oct 22 09:48:54 zaira2 cockpit-ws: arabella.xxx: ssh-ed25519 host key for server is not known: 23:09:0b:c3:b1:1c:c4:2d:fc:37:fc:45:f3:27:91:53 Oct 22 09:56:04 zaira2 cockpit-ws: salome.xxx: ssh-ed25519 host key for server is not known: 61:70:b2:cf:7d:a5:b9:27:40:68:3b:57:4f:ab:40:48 Oct 22 09:58:28 zaira2 cockpit-ws: nabucco.xxx: ssh-ed25519 host key for server is not known: 57:b0:f0:6c:f3:4d:f9:b3:55:81:08:60:e5:81:a0:23 Oct 22 10:07:11 zaira2 cockpit-ws: rigoletto.xxx: ssh-ed25519 host key for server is not known: 36:0e:80:79:fd:ec:e5:47:c3:e4:d1:de:86:27:9b:b1 ... What can be wrong with server adina? Fuji

How do I configure firefox to log in to cockpit web ui?
by Fuji San 22 Oct '15

22 Oct '15

Hello, I installed cockpit on my server and I could log in as root. But then I installed freeipa-server on my server and configured firefox to log in the ipa web ui using kerberos. Now when I want to login to the web ui of cockpit on port 9090, I get this : http://i.imgur.com/9YEIYRo.png No field to enter username and password. It's probably due to the kerberos config for ipa. Any idea how I can configure cockpit/firefox to connect again to the cockpit web ui? Fuji
