Hi, how do I allow lighttpd access to a directory like this: dr-xrwxr-x. lighttpd example unconfined_u:object_r:samba_share_t:s0 files_articles I tried to create and install a selinux module, and it didn´t work. The non-working module can not be removed, either: semodule -r lighttpd-files_articles.pp libsemanage.semanage_direct_remove_key: Unable to remove module lighttpd-files_articles.pp at priority 400. (No such file or directory). semodule: Failed! Currently, only read access is required.

Being like this, selinux is entirely unmanagable. Does it even do any more good than it keeps getting in the way?

[Slightly OT] Use CentOS to create a bootable Mac OS X DVD from dmg file?
by Nicolas Kovacs 24 Sep '17

24 Sep '17

Hi, Sorry if this is only half-CentOS-related. In my office, I'm running CentOS on all my systems (server, workstation, laptop, sandbox PCs). A colleague brought me her MacBook Pro to upgrade it from OS X 10.5.7 to 10.11.6. I downloaded the 5.8 GB dmg file and now I wonder how to create a bootable DVD with this using only Linux tools. 1. Can I simply burn this as a data DVD with K3B? 2. Or do I have to jump through burning loops using dmg2img, mount -t hfsplus, etc. I only have a couple of double layer DVDs here, so before burning a pair of expensive coasters, I thought I'd rather ask here.

Connecting to internet with USB tethered iphone
by Larry Martell 24 Sep '17

24 Sep '17

I am trying to get a centos 6 system on the internet with a tethered iPhone. I can see the phone with lsusb as bus 001 device 011. A post on stackoverflow said I would need to run "# ip link set usb0 up && dhcpcd usb0" But how do I reference my phone in that command?

vmplayer for linux 12.5.7 on CentOS 7.4
by Jerry Geis 23 Sep '17

23 Sep '17

So after the update to CentOS 7.4 vmplayer 12.5.7 is no longer working. I can't believe after all the time that RHEL 7.4 has been released and VMware has not fixed the issue and made a new release. What is everyone doing that used the vmplayer on linux? Thanks, Jerry

Error "corrupted or uncleanly shut down, renaming and replacing" in CentOS 7 clean install
by C. L. Martinez 23 Sep '17

23 Sep '17

Hi all, I have installed two new CentOS 7.1708 (fully patched, kernel release is 3.10.0-693.2.2.el7.x86_64) as virtual guests, one is using lvm and the other not and both use XFS as filesystem. In both, I see the following systemd's error after a few minutes: systemd-journald[779]: File /run/log/journal/3abe0470ce564669b797cb4c416f1ac0/system.journal corrupted or uncleanly shut down, renaming and replacing. Is it a bug? Or do I need to change some option in journald.conf's file? Actually, I have changed Storage's option to "volatile". Thanks. -- Greetings, C. L. Martinez

owncloud on CentOS - I have problems installing/updating recently
by Valeri Galtsev 22 Sep '17

22 Sep '17

Dear Experts, after quite some time of praising ownclowd, I started having problems with installing and updating desktop owncloud-client on CentOS. Namely, yum repository owncloud.org points to for rpm/yum based Linux distributions lives on suse.com site (well, for all flavors of Linux, actually). I remember it smelled fishy for me the first time I installed ownclouud on CentOS using that repository living at suse.com. It worked, however, for quite some time, but recently it just times out for me, even what owncloud.org currently gives as yum.repo information (which has changed from what was in the past). Does anybody have any suggestion? Am I the only one (thus, making my "pilot error"), or others have the same? Did someone find workaround? Incidentally, another system - FreeBSD - I run on my laptop and workstation, has no trouble with owncloudclient package. But I have to give graduate students Linux, and prefer CentOS Linux, so I do need to make it work even if I end up compiling it all the time myself (sigh, I hope, not). Thanks a lot in advance for all your help!

webkit on CentOS 7.4
by Jerry Geis 22 Sep '17

22 Sep '17

Hello is the webkit with CentOS 7.4 compiled with ENABLE_MEDIASOURCE ? When I call the set_media_source function with TRUE and then ask get_media_source function for the value it returns TRUE. I presume it would no return TRUE if its not enabled. However, my webpage with a video tag using webkit is not finding the MediaSource. Thanks, Jerry

upgrade to 7.4 ZFS issue
by Thomas Roth 22 Sep '17

22 Sep '17

Hi all, I have a server running 7.3 using the zfs-kmod packages from zfsonlinux.org. For the update to 7.4, I followed https://github.com/zfsonlinux/zfs/wiki/RHEL-&-CentOS: removal of all zfs - and related packages and installation of the zfs-release.7.4.noarch.rpm Afterwards, yum will find almost all packages from that repository - except for the zfs-0.7.1-1.el7_4.x86_64.rpm itself ("ZFS command line utilities"). However, the package is there, I can get it via wget! Of course I tried cleaning yum + caches, not removing the zfs packages, removing them before reboot, removing them after booting into 3.10.0-693 - all of which makes no difference. On a fresh installation (aka starting with 7.4), this problem does not occur. Regardless of any ZFS specifics, what could cause yum to exclude one single package file from an otherwise perfectly accessible repo? Cheers, Thomas
