Everything else being equal, are the errata that are rolled up in upstream 7.1 available in this particular date-based snpashot? Thanks kindly, Eugene

This is great, thanks. Shouldn't this be pushed to mirrors? Lucian -- Sent from the Delta quadrant using Borg technology!

SELinux kills Cassandra based website
by Tim Dunphy 05 Mar '15

05 Mar '15

Hey all, There's a website I help run that uses the Cassandra DB as its database. I notice that if I run the web server in SELinux permissive mode, the site works fine. But if I put it into enforcing mode, the site goes down with this error: Warning: require_once(/McFrazier/PhpBinaryCql/CqlClient.php): failed to open stream: Permission denied in /var/www/jf-ref/includes/classes/class.CQL.php on line 2 Fatal error: require_once(): Failed opening required '/McFrazier/PhpBinaryCql/CqlClient.php' (include_path='.:/php/includes') in /var/www/jf-ref/includes/classes/class.CQL.php on line 2 I've tried performing a chcon -R command on both the /McFrazier and the /var/www/jf-ref directories. But there's no change to the site being up. Can I get some opinions on how to get this working under SELinux? Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Gnome2 Desktop mute buttons for mic and video
by James B. Byrne 05 Mar '15

05 Mar '15

CentOS-6.6 Does anyone know of an application that would provide a 'mute' buttons for video and audio that could be used from a desktop panel? Ideally this would show the status (muted/cloaked or open mic/recording) of each. Presently, turning audio and video pick-ups off and on is rather cumbersome. And I often forget what state I have left them in. Which occasionally makes for some confusing moments trying to debug a non-existent problem.

"Machine Check Exception: 4 Bank 0: 9000000020000003" when boot CentOS 7, with Intel CPU E3845, and BIOS option "EIST" enable.
by Chaoyong 05 Mar '15

05 Mar '15

My hardware is: CPU: Intel(R) Atom(TM) CPU E3845 @ 1.91GHz and it supports EIST(Enhanced Intel SpeedStep Technology). OS: CentOS 7(kernel-3.10) When I set the BIOS options "CPU configuration >> EIST" to "enable", it appears a kernel panic when the system is starting up. Here is what I am seeing: ...... Fast TSC calibration failed. [Hardware Error] CPU 3: Machine Check Exception: 4 Bank 0: 9000000020000003 ...... Machine check: Invalid. Panic - not syncing. Fatal machine check on current CPU. Rebooting in 30 seconds. By reading the Intel-programming-manual, the MCE means: Machine Check Exception: 4 -- MCG_STATUS_MCIP Bank 0: 9000000020000003 -- 0x9000 -- 1001 0000 0000 0000 -- IA32_MCi_Status MSR register 0x0003 -- 0000 0000 0000 0011 -- External Error, The BINIT# from another processor caused this processor to enter machine check. and seems it is an external bus error. If I DISABLED the BIOS option "EIST", there will be no error or panic. If I change to CentOS 6.5/6.6(kernel 2.6), there will be no error or panic even when "EIST" is ON. So, it should be a bug in kernel source of CentOS 7(kernel-3.10). Ps: kernel source v3.10 from kernel.org is OK Any help would be greatly appreciated. Thanks.

selinux allow FTP
by Tim Dunphy 05 Mar '15

05 Mar '15

Hey folks, How would I allow a user to connect to an FTP server, upload and download files and delete files as well, if that server is in enforcing mode for SELinux? I'm using proftpd 1.3.5 on CentOS 7. Thank you! Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

Extdata / Extprograms Plugins for Dovecot Pigeonhole?
by E.B. 04 Mar '15

04 Mar '15

Hello, I want to install Dovecot Pigeonhole and use the Extdata and Extprograms plugins. According to the dovecot documentation[1,2], those plugins need to be compiled. So two questions: * Are either of these plugins built into the Pigeonhole that is available in the CentOS 7 extras repo? * Is it possible to use these plugins with Pigeonhole installed from yum? Does the compilation requirement mean that I have to remove not only Pigeonhole, but also Dovecot itself from my system and build everything by hand? :-( PS - Is there another version of Pigeonhole in a repo elsewhere (like EPEL or DAG?) that might have what I want?

Dovecot Pigeonhole version in extras repo?
by E.B. 04 Mar '15

04 Mar '15

Hi, I want to install Dovecot Pigeonhole from the yum Centos extras repo, but "yum info" reports the version number not of the plugin but of dovecot itself. Can anyone say what the Pigeonhole version is currently for the extras repo for CentOS 7?

Memory issue in kernel sctp implementation
by Danny Smit 04 Mar '15

04 Mar '15

Dear all, I'm running into a possible memory issue with the SCTP implementation in CentOS 6, using lksctp-tools. So far I've not seen the problem with other distributions yet. The problem is that whenever a SCTP client connection is initiated to a second host and port at which no SCTP server application is listening The scenario is simple: - call socket() to create a socket. - call sctp_connectx() to establish a connection. The last call is repeated periodically to retry to establish a connection. When looking on the wire using wireshark it shows that an SCTP INIT packet is sent to the second host, which replies with an SCTP ABORT. This is exactly according to the SCTP specification. However it appears ABORT isn't propagated into to application layer that calls sctp_connectx(). Furthermore, because reconnect attempts are made, a steady memory increasement occurs. Looking at /proc/meminfo, the increasement occurs in SUnreclaim, the kernel slab cache. Can you advice if this can be an issue with the SCTP implementation in the kernel? Maybe an issue solved upstream, but not (yet) backported into centos 6? It applies to the following package versions (also to older kernels): - kernel-2.6.32-504.8.1.el6.x86_64 - lksctp-tools-1.0.10-7.el6.x86_64 Regards, Danny Smit
