CentOS - SIG Hardening
by Earl A Ramirez 22 Apr '15

22 Apr '15

Dear CentOS Development Team, I am interested in starting a new SIG or merging with the ‘Hardening’ SIG, I didn’t find sufficient information about the hardening SIG. I have been on the mailing list for some years and I have noticed a number of concerns with regards to security, e.g. the default sshd_config, gnome user list and more. My goal is to use the base and modify the OS with these changes and make it available for the CentOS community, I will mention this on the mailing list to get the community feedback so that they can have an opportunity to contribute, and more importantly get an OS that meets their needs, with regards to their security concerns. I’m not too familiar with the CentOS build system, however I started to read up on it and practice to get a feel on things. Some of the things that I will like to change are as follow: SSH: disable root (uncomment 'PermitRootLogin' and change to no) enable 'strictMode' modify 'MaxAuthTries' modify 'ClientAliveInterval' modify 'ClientAliveCountMax' Gnome: disable Gnome user list Console: Remove reboot, halt poweroff from /etc/security/console.app Looking forward for your response on how can I proceed with this? -- Kind Regards Earl Ramirez

Probably no CentOS SCLo SIG sync-up meeting (2015-04-22)
by Honza Horak 22 Apr '15

22 Apr '15

Unfortunately, I've just learnt can't make it for today's 3 UTC sync-up meeting, so unless anybody else is volunteering to chair it after such a short notice, we can skip and talk on IRC/ML. Just for getting some update, we've just had an earlier talk about tags for SCL, cleared up few things and agreed to continue with further discussions about tags/branches on IRC. Honza

hi I guess this is more for Jim / Ralph : but is there anyway to get mantis to send out an email nightly, with a list of 'new' bugs reported during the last 24 hrs ? Additional win if we can also get a list of bugs that have had no activity for > 60 days and are not in status: Feedback Regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Atomic devel builds automation
by Karanbir Singh 21 Apr '15

21 Apr '15

hi, The Atomic devel builds are now running from cron again, after a 2 week lag, they now run every 12 hours, midnight and midday UTC. These builds now also run with a complete toolchain update taking place before the build gets run. The build script is now in git itself : https://github.com/CentOS/sig-atomic-buildscripts/blob/master/build_ostree_… and the cron worker will git pull, before running this, so updates are consumed immediately. That does make line 10 to 12 of this script completely redundant, but I've left it in as an indicator. Build runs are logged at : http://buildlogs.centos.org/centos/7/atomic/x86_64/Builds/ And the ostree repo remains at : http://buildlogs.centos.org/centos/7/atomic/x86_64/repo/ Once the installer image starts building, we can push that to http://buildlogs.centos.org/centos/7/atomic/x86_64/ which would in turn allow the vagrant and image builds to also run. Regards, -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

summary for tags/branches in SCLo SIG
by Honza Horak 20 Apr '15

20 Apr '15

Hi guys, few days back we talked about tags and branches names on the SCLo meeting and I found out that I missed the important CBS meeting [1].. which I'm sorry.. Anyway, we ended with things in our heads but I can't find anything written, so I tried to summarize what should be the result (as I understood it) and would like to ask for correction if I failed to get it... I realize that rh-mariadb100 confuses people, because it includes rh- in the name, but for tags/branches names it is nothing more than part of the collection name. If the dash is an issue, then we may use underscore (rh_mariadb100) or just rhmariadb100 if necessary for tags/branches, but mariadb100 alone is simply not correct. What is more, not all collections in RHSCL have rh- prefix (existing collections) although the new collections should have it in the future. Anyway, I rather took another collection (that doesn't use rh- prefix) to not complicate it even more and the bellow are examples of two collections within SCLo -- one that *is part of RHSCL* (mariadb55) and one that is only part of SCLo (mariadb55extra; could include packages that extend mariadb55 collection for example), which *is not part* of RHSCL. final tags (and repositories) for non-RHSCL collections (include also packages from rhscl repos bellow): sclo6-sclo-release sclo6-sclo-candidate sclo6-sclo-testing sclo7-sclo-release sclo7-sclo-candidate sclo7-sclo-testing final tags (and repositories) for RHSCL collections (separate in order to allow using the sclo- repositories together with RH's rhscl channel, the same as epel is used): sclo6-rhscl-release sclo6-rhscl-candidate sclo6-rhscl-testing sclo7-rhscl-release sclo7-rhscl-candidate sclo7-rhscl-testing build tags: sclo6-el6-mariadb55extra-sclo-build sclo7-el7-mariadb55extra-sclo-build sclo6-el6-mariadb55-rhscl-build sclo7-el7-mariadb55-rhscl-build (el6- and el7- part used for keeping the disttag in the name as agreed from the beginning for all SIGs -- that was mentioned as a requirement before already) build targets: sclo6-el6-mariadb55extra-sclo sclo7-el7-mariadb55extra-sclo sclo6-el6-mariadb55-rhscl sclo7-el7-mariadb55-rhscl git branches under sclo/ project: sclo6-mariadb55extra-sclo sclo7-mariadb55extra-sclo sclo6-mariadb55-rhscl sclo7-mariadb55-rhscl git branches under rpms/ project: sclo6-mariadb55extra-sclo sclo7-mariadb55extra-sclo sclo6-mariadb55-rhscl sclo7-mariadb55-rhscl Are we on the same page with the schema above?

But I have been thinking further about how to provide SCST RPMs for CentOS.

Getting started on contributing to CentOS
by Gow Tham 18 Apr '15

18 Apr '15

Hi, I have been using CentOS for quite a while now and would like to switch from the user to a contributor. kbsingh mentioned on the ilug mailing list that this was a good time to get acquainted with the community because of the influx of new users due to the Google Summer of Code event. Looking at the Summer of Code ideas page, (http://wiki.centos.org/GSoC/2015/Ideas ), the one about writing a Lightweight Cloud instance contextualisation tool seemed like a good place to start. How can I start with it ? -sg
