Dear all, 1. Is it possible to convert centos iso file to vmlinuz, initrd and rfs_raw.img. 2. Can I use only vmlinux, initrd and rfs_raw.img to install via pxeboot.

The easiest way for Fedora 14 to Centos 6 migration?
by Frantisek Hanzlik 08 Jul '14

08 Jul '14

I manage several Fedora 14 servers. They was not upgraded due to several reasons (systemd unreliability, K12LTSP support absence), some newer packages I was building & updating manually, some other (OpenOffice, Mozilla) was possible update from projects binaries. Now I consider the options to migrate them to Centos 6, possibly the easiest possible way. What I'd like is some as yum configuration files replacement of those from Fedora with files from Centos - and then simply do "yum update". Has anyone tried to do a similar migration? What procedure would you recommend? TIA, Franta Hanzlik

Today's Topics: 1. Release for CentOS-7 on x86_64 (Karanbir Singh) 2. CentOS 7 Release - Zero Day Updates (Johnny Hughes) ---------------------------------------------------------------------- Message: 1 Date: Mon, 07 Jul 2014 19:30:23 +0100 From: Karanbir Singh <kbsingh(a)centos.org> Subject: [CentOS-announce] Release for CentOS-7 on x86_64 To: CentOS Announcements List <centos-announce(a)centos.org> Message-ID: <53BAE73F.5010000(a)centos.org> Content-Type: text/plain; charset=ISO-8859-1 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We would like to announce the general availability of CentOS Linux 7 for 64 bit x86 compatible machines. This is the first release for CentOS-7 and is version marked as 7.0-1406 First, please read through the release notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 - these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from the users. - ---------- Updates, Sources and DebugInfos Since the upstream EL7 release, there have been some updates released - - these have been built and are being pushed to the CentOS mirror network at the moment. They will be available within the next 24 hrs. - From this point on we will aim to deliver all updates within 24 to 48 hrs of upstream releases. For the first time, this release was built from sources hosted at git.centos.org, however srpms being a byproduct of the build and also considered critical in the code and buildsys process are being published to match every rpm we release. Sources will be available from vault.centos.org in their own dedicated directories to match the corrosponding binary rpms. Since there is far lesser traffic to the source rpms compared with the binary rpms, we are not putting this content on the main mirror network, however if users wish to mirror this content they can do so using the reposync command available in the yum-utils package. All source rpms are signed with the same key used to sign their binary counterparts. Debuginfo packages are also being signed and pushed. They should be online by the end of this week, July 11th. Yum configs for both sources and debuginfo packages are included in the default centos-release package on every install. For the CentOS-7 build and release process we adopted a very open process. The output of the entire buildsystem is made available, as its built, at http://buildlogs.centos.org/ - we hope to continue with that process for the life of CentOS-7, and attempt bringing CentOS-5 and CentOS-6 builds into the same system. - ---------- Numbering CentOS 7.0-1406 introduces a new numbering scheme that we want to further develop into the life of CentOS-7. The 0 component maps to the upstream realease, whose code this release is built from. The 1406 component indicates the monthstamp of the code included in the release ( in this case, June 2014 ). By using a monthstamp we are able to respin and reissue updated media for things like container and cloud images, that are regularly refreshed, while still retaining a connection to the base distro version. In order to facilitate Special Interest Groups to further extend the CentOS Linux platform, we are also using component codes. The main distro is, therefore, titled 'Core'. SIGs would be able to adopt any name they need and deliver that by overriding the base centos-release rpm. - ---------- Download In order to conserve donor bandwidth, and to make it possible to get the mirror content sync'd out as soon as possible, we recommend using torrents to get your initial installer images: Details on the images is available on the mirrors at http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt - that file clearly highlights the difference in the images, and when one might be more suiteable than the others.

In the past its only been iso media and install tree's, but with CentOS-7 we are also going to deliver: = Docker Images = Cloud Images in vendor ecosystems ( HPCloud, RackSpace, AWS, Google Compute etc ) = Cloud Images for direct download and consumption in on-premise infra ( RDO/OpenStack, CloudStack, OpenNebula and Eucalyptus ) = Given the popularity of the minimal install ISO in CentOS-6, we are going to try and deliver a minimal install ISO for CentOS-7 as well. One key challenge here is that the installer image has grown to nearly 360MB, and getting enough content into a CD size image is proving hard. = A community build system is in the works, we hope to have that functional by the end of this month ( July 2014 ), allowing us to set up a contributor base in the Special Interest Groups to extend and further develop layers and variants on CentOS Linux = Special Interest Groups including Xen on CentOS, CentOS Storage and CentOS Atomic Host are starting to gain traction, expect to see content delivered from those groups in the near future. = As a part of the expanded Core efforts, we are also going to attempt to deliver a CentOS-7 release for 32bit x86, ARM and PowerPC in the coming months. If you are interested in joining any of these efforts, signup for the CentOS-devel list at http://lists.centos.org/ and send in a self intro email and what areas you are interested in helping out with. - ---------- Dojo We try and organise Dojo's in various parts of the world as a one day event, to bring together people who use CentOS and others who are keen to learn about CentOS. The day's focus is on sharing technical knowledge and success stories. Its also a great place to meet and talk about upcoming technologies and learn how others are using them on CentOS Linux. 04th Aug '14 Cologne, Germany : http://wiki.centos.org/Events/Dojo/Cologne2014 25th Aug '14 Paris, France : http://wiki.centos.org/Events/Dojo/Paris2014 29th Oct '14 Barcelona, Spain: http://wiki.centos.org/Events/Dojo/Barcelona2014 This autumn and winter we also hope to host Dojos in New York City USA, Timisoara Romania and Bangalore, Pune and New Delhi in India. Please keep an eye on the page at http://wiki.centos.org/Events for details on these venues. - ---------- Getting Help The CentOS ecosystem is sustained by community driven help and guidance. The best place to start for new users is at http://wiki.centos.org/GettingHelp - ---------- Contributors This release was made possible due to the hard work of many people, foremost on that list are the Red Hat Engineers for producing a great distribution, without them CentOS Linux would look very different. The following people made exceptional contributions in this build, test release process for CentOS-7 : Akemi Matsuno-Yagi Alain Reguera Delgado Alan Bartlett Andreas Thienemann Anssi Johansson Athmane Madjoudj Bonnie King Brian Stinson Carl Trieloff Christoph Galuschka Fabian Arrotin James Moger Jeff Sheltren Jim Perrin Johnny Hughes Jr Karanbir Singh Karsten Wade Kay Williams Manuel Wolfshant Marcus Moeller Michael Scherer Mike McLean Pat Riehecky Ralph Angenendt Stephen John Smoogen Trevor Hemsley Tru Huynh Tuomas Kuosmanen Tuomo Soini Tyler Parsons - ---------- Thanks I?d also like to thank our donors and sponsors for their continued support for the project. Its down to their help that we were able to deploy enough resources to run the Public QA process for CentOS-7; as a data point we ran nearly 300 - 350mbps of sustained bandwidth for the last 3 weeks that we?ve had the Public QA running. And thanks to everyone who contributed with ideas, code, test feedback and promoting CentOS into the ecosystem.

How to enable sound for other users but the one who owns the current session
by wwp 08 Jul '14

08 Jul '14

Hello there! I'm trying to get sound from applications running from other users bug the one who owns the current GNOME sessions. Typically, my default user is "A" and he's running the GNOME session, logged in graphically. From this session, I open terminals, su to other users (B or C, non-root) and run mplayer or firefox. No sound for these. Adding those users to the "audio" group didn't help. Any idea how to do this? Regards, -- wwp

block level changes at the file system level?
by Lists 07 Jul '14

07 Jul '14

I'm trying to streamline a backup system using ZFS. In our situation, we're writing pg_dump files repeatedly, each file being highly similar to the previous file. Is there a file system (EG: ext4? xfs?) that, when re-writing a similar file, will write only the changed blocks and not rewrite the entire file to a new set of blocks? Assume that we're writing a 500 MB file with only 100 KB of changes. Other than a utility like diff, is there a file system that would only write 100KB and not 500 MB of data? In concept, this would work similarly to using the 'diff' utility... -Ben

corruption of in-memory data detected (xfs)
by Alexandru Cardaniuc 07 Jul '14

07 Jul '14

Hi All, I am having an issue with an XFS filesystem shutting down under high load with very many small files. Basically, I have around 3.5 - 4 million files on this filesystem. New files are being written to the FS all the time, until I get to 9-11 mln small files (35k on average). at some point I get the following in dmesg: [2870477.695512] Filesystem "sda5": XFS internal error xfs_trans_cancel at line 1138 of file fs/xfs/xfs_trans.c.

CentOS-6.5 LiveDVD problem
by James B. Byrne 07 Jul '14

I downloaded the Live DVD for CentOS-6.5 and burned a DVD-R using a CentOS-6.5 desktop. To test the validity of the new DVD I then rebooted the same desktop using the same Live DVD. No matter which Live DVD boot option I choose I see this after the splash screen completes the Circle (sounds like a good title for a novel). <--- Kernel panic - Not syncing - Attempting to kill init!

It is therefore common to compress a file that is itself an archive, such as those created by the tar or cpio Unix programs.[2]" "xz is a lossless data compression program and file format which incorporates the LZMA compression algorithm. xz can be thought of as a stripped down version of the 7-Zip program. xz has its own file format rather than the .7z format used by 7-Zip (which lacks support for Unix-like file system metadata[2])." https://en.wikipedia.org/wiki/7-Zip: "By default, 7-Zip creates 7z format archives with a .7z file extension. Each archive can contain multiple directories and files. As a container format, security or size reduction are achieved using a stacked combination of filters. These can consist of pre-processors, compression algorithms, and encryption filters." So either tar.xz or 7z container, and looks like LZM2 is only option, with several switches for xz for block reduction. And, no, --help does not actually help with assessing if xz is viable replacement for some particular purpose, testing is needed. P.S.

Mon morn

07 Jul '14

And, no mourn. Took three-quarters of an hour, which someone inconvenienced Beecher, but the server I came in so early to reboot did it's thing (think DOS or Windows chkdisk, except with a *lot* more disk), and I got the memory that Dell shipped me last Thurs into the other server, and everything's up swimmingly. Oh, and I'd gotten a email the other day - for some reason, they thought the card I'd reserved the room at the con with expired before our stay, so I updated their info, and got a thanks from Rob, who I've been dealing with. I replied to that before we left this morning, and mentioned it had been a week, and we hadn't heard anything about Bath, etc... and I got a nice email from him, saying he'd walk down the hall and prod them. Now, let me reattach my IV of tea/caffeine....

Btrfs actually does sport built-in compression as a mount argument/flag and the delta snapshots works beautifully well but I wouldn't dare to use it with any kernel previous to 3.13; in fact best practice would be to use it with kernel 3.14.x or later, preferably 3.15.x and later.

semi-OT: perl question
by m.roth＠5-cent.us 03 Jul '14

03 Jul '14

We've had a ton of selinux errors recently, and the other day, one of the managers here, after I started inquiring what their perl CGI was doing, found a way to reproduce the issue at will. It seems that before I upgraded their servers from CentOS 5.x, they were trapping interrupts such as a browser breaking the connection before getting a response, and under CentOS 6, it's looking like the traps aren't working. Has anyone seen anything like that? mark

Miredo server for Centos 6
by Robert Moskowitz 03 Jul '14

03 Jul '14

On delving deeper into Miredo support, it seems that Miredo Server is a separate program from the Miredo client/relay. And that there is no Miredo Server available for Centos 6. Not in EPEL 6, or repoforge. So far the maintainer of Miredo for Fedora/EPEL has not reponded to a query on its status for EPEL 6. I have to ask on repoforge about miredo-server. Anyone know of anywhere else to look? I suppose I can bring up a Fedora 20 box, as this is 'just' a testbed. But to move the testbed out of my network into the corp testbed, I need it for Centos. thanks

exiting tmux sessions
by James B. Byrne 02 Jul '14

02 Jul '14

I am experimenting with tmux. I have run into a behaviour that I would like to change. Idf I connect to a single host multiple times via tmux, when I exit one tmux window then all the windows report their session closed. Is there anyway of changing this behaviour in .tmux.conf so that only the session exited closes or, as might be the underlying problem, any way of ensuring that a second tmux connection opens its own session that remains independent of the first? -- *** E-Mail is NOT a SECURE channel *** James B.

How to enable EDAC kernel module for checking ECC memory?
by Lists 02 Jul '14

02 Jul '14

In order to support ZFS, we upgraded a backups server with a new, ECC motherboard. We're running CentOS 6 with ZFS on Linux, recently patched. Now, I want to enable EDAC so we can check for memory errors (and maybe PCI errors as well) but so far, repeatedly pounding on the Google hasn't yielded exactly what I need to do to enable EDAC. One howto was covering PCI and edac, but "modprobe edac_mc" didn't work. Here's some information below, How do I get edac up and running? Many howtos cover how to use edac-ctl and edac-util, but none seem to cover how to determine what module to load into the kernel. [root@hume ~]# modprobe edac_mc FATAL: Module edac_mc not found. [root@hume ~]# lsmod | grep edac [root@hume ~]# cat /proc/version Linux version 2.6.32-431.11.2.el6.x86_64 (mockbuild(a)c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Tue Mar 25 19:59:55 UTC 2014 [root@hume ~]# modprobe edac_mce FATAL: Module edac_mce not found.

I have a conference call in 15min where one of the discussions will be putting up my Teredo testbed, and this system is what is handy for the Teredo (Miredo) server. So I rushed more than I should have. But I did piece it all together. Now I can pull the rpmforge Miredo code and get that up. Too bad that it is not in EPEL 6; the Miredo maintainer has not commented on why it is not there.

remote yum update aborted with session closing - won't boot
by Robert Moskowitz 02 Jul '14

02 Jul '14

I was upgrading a system remotely from Centos 6.3 to 6.5 via VNC. Now the system will not boot. Or at least without bringing up the console and switching to the older kernel. The last messages I see in /var/log/messages are: Jul 1 14:53:51 rigel yum[3220]: Updated: scl-utils-20120927-8.el6.i686 Jul 1 14:53:53 rigel gnome-keyring-daemon[2710]: dbus failure unregistering from session: Connection is closed Jul 1 14:53:53 rigel gnome-keyring-daemon[2710]: dbus failure unregistering from session: Connection is closed Jul 1 14:53:54 rigel gnome-keyring-daemon[2822]: dbus failure unregistering from session: Connection is closed Jul 1 14:53:54 rigel gnome-keyring-daemon[2822]: dbus failure unregistering from session: Connection is closed yum update reports 'No Packages marked for Update'. How do I trouble shoot this? I am assuming that I only got a partially completed update.

I have the same problem talking secure identities inside my company. It is clear to me, but others just miss the important points. And you get frustrated going back to 'basic principles' and teaching them again.... So thanks for putting up with me, who rarely has to dig into these parts of systems. > >> But how do I determine what package from the new kernel > no idea what is unclear in "remove any package from the new kernel" > which maybe kernel, kernel-headers, kernel-devel..... Ah, perhaps my dyslexia, but I was wondering what drivers or other things I might have to contend with. If it is 'just' kernel* I can deal with that. > >> Do I erase the new kernel then install it again > i said: and after that "yum upgrade" again > > man if you remove that broken packages a "yum upgrade" pulls them simply as if > they where never be installed and the rpmscripts will generate a new initrd > Again, a bit of 'magic' here that 'yum upgrade' knows what should be present and sees to it that these packages get installed. Again, thinking that more than kernel* would need to be removed, then how would it get reinstalled? So off I go try again. The box had been off for a year; it was a DNSSEC tester (I need to replace my router(s), I think to get DNSSEC working right, and that project is on hold). So it was quite back-leveled. If I end up needing to do a reinstall because I stumbled, so be it as a learning lesson.

gdb question
by Les Mikesell 01 Jul '14

01 Jul '14

If you are trying to debug a core dump from a different machine, how do you tell gdb where to look for the debug info files to match the shared libs that you have in a non-standard location? It finds the shared libs themselves with a 'set solib-absolute-path' directive, but it doesn't look for the corresponding (relative) usr/lib/debug/... file that you get if you extract the debuginfo rpm in the same place. And if I set debug-file-directory to the top of the tree, it wants to also add the solib-absolute-path to that. Is there some way to make it realize that the top of the tree is the same for both? -- Les Mikesell lesmikesell(a)gmail.com

Is the Miredo server available for Centos? A quick check of 'yum install miredo*" came up empty. I have miredo for Fedora 20, but I want the server to be Centos... thank you.

Google Hangout Plugin Does Not Work For Other Users
by Mark LaPierre 01 Jul '14

01 Jul '14

Hey All, I've got the Google Talk plugin installed at: File: libnpgoogletalk.so Path: /opt/google/talkplugin/libnpgoogletalk.so Version: State: Enabled Version: 5.4.2.0 And the Google Talk Plugin Video Renderer at: File: libnpo1d.so Path: /opt/google/talkplugin/libnpo1d.so Version: State: Enabled Version: 5.4.2.0 When I start of join a Google Hangout all works as expected for me. When another user on my system tries to start/join a Hangout she gets an error telling her that the plugin is not installed. When I check "about:plugins" under her login it says that the plugin is installed in the same location/version. I checked the file access settings and found all is set as expected, 755, on the plugin and it's directories all the was down to root. -rwxr-xr-x. 1 root root 273496 Jun 7 17:38 libnpgoogletalk.so -rwxr-xr-x. 1 root root 229784 Jun 7 17:38 libnpo1d.so Shouldn't this work system wide? If I try to install the plugin as firefox seems to think I should I'm told that I already have the pluging installed, which is true. Does anyone have a clue why it's refusing to start? -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

GUI Question
by Deno Sayangda Dangpaliw 01 Jul '14

01 Jul '14

Hi, There's something weird happening to my CentOS VMs, cannot switch back to GUI. Black screen with a single underscore character at top left of the screen. Ok so I have ESXI 5.1 host, with 3 VM all running CentOS. I rebooted the esxi host yesterday for a power maintenance. All went well... until I switched console on the vms. I was able to login using the GUI, then I pressed Alt F5, then I was sent to the text console... I usually do this to save energy. I did the same for all the Centos vm... now I wanted to switch back to GUI but I can't. I even pressed all the keys from F1 to F12 but were not able to get back to the GUI for all the VMs. Can you please advise where Im missing? Regards, Deno

Does it matter that the application user has to login so that the capistrano deply receipes will run correctly? Also this deploy makes use of rbenv which is another user login dependent item (requires a shim in .bash_profile). Does that have any impact on the choice? Finally, and only peripherally related, what are the SELinux settings, boolean or profile, required on CentOS-6.5 to get Apache mod-passenger to run without generating avc's? -- *** E-Mail is NOT a SECURE channel *** James B.

3D Acceleration with Matrox MGA G200EH?
by Dave Johansen 30 Jun '14

30 Jun '14

I'm running on a machine with a Matrox MGA G200EH but it doesn't appear that the 3D acceleration is being used (for example Google Earth lists the driver as being Mesa). Is there an additional driver that I need to install to enable the 3D acceleration functionality? Or something else I need to do? Thanks, Dave

iostat results for multi path disks
by David Goldsmith 30 Jun '14

30 Jun '14

Here is a sample of running iostat on a server that has a LUN from a SAN with multiple paths. I am specifying a device list that just grabs the bits related to the multi path device: $ iostat -dxkt 1 2 sdf sdg sdh sdi dm-7 dm-8 dm-9 Linux 2.6.18-371.8.1.el5 (db21b.den.sans.org) 06/20/2014 Time: 02:30:23 PM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sdf 0.66 52.32 3.57 34.54 188.38 347.52 28.13 0.14 3.62 0.87 3.31 sdg 0.66 52.29 3.57 34.56 189.79 347.48 28.18 0.14 3.72 0.87 3.32 sdh 0.00 0.00 0.00 0.00 0.00 0.00 14.19 0.00 2.90 2.90 0.00 sdi 0.00 0.00 0.00 0.00 0.00 0.00 14.19 0.00 2.87 2.87 0.00 dm-7 0.00 0.00 8.46 173.75 378.17 695.00 11.78 3.41 18.68 0.35 6.46 dm-8 0.00 0.00 8.46 173.75 378.17 695.00 11.78 3.41 18.68 0.36 6.47 dm-9 0.00 0.00 8.46 173.75 378.17 695.00 11.78 3.41 18.68 0.36 6.48 Time: 02:30:24 PM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sdf 0.00 54.00 7.00 48.00 88.00 408.00 18.04 0.12 2.11 1.20 6.60 sdg 0.00 13.00 1.00 26.00 4.00 156.00 11.85 0.01 0.52 0.48 1.30 sdh 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdi 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-7 0.00 0.00 8.00 141.00 92.00 564.00 8.81 0.25 1.69 0.53 7.90 dm-8 0.00 0.00 8.00 141.00 92.00 564.00 8.81 0.25 1.70 0.54 8.00 dm-9 0.00 0.00 8.00 141.00 92.00 564.00 8.81 0.25 1.70 0.54 8.00 sdf,sdg,sdh,sdi - four paths for LUN (sdf and sdg are the active paths) dm-7 - device-mapper pseudo device for the mpath device dm-8 - device-mapper pseudo-device for the partition spanning the entire mpath device dm-9 - device-mapper pseudo-device for the LVM LV created on the mpath device The first sample from iostat is the historical data so lets ignore it. The second sample are the stats for a 1 second interval. I see the stats for sdf and sdg are roughly equal but they differ — they are the two active paths that are both being used. I see the stats for dm-7, dm-8 and dm-9 are almost completely identical - makes sense as they really represent the same “disk”. What confuses me is the fact that all the stats for sdf/sdg don’t add up to be equivalent to the dm-[789] devices For the rkB/s and wkB/s columns, the numbers for sdf and sdg add up to equal the numbers for dm-9. But for the first four columns: Column sdf/sdg dm-9 ====== ============= ==== rrqm/s 0.0 + 0.0 = 0.0 0 wrqm/s 54.0 +13.0 = 67.0 0 Very different r/s 7.0 + 1.0 = 8.0 8.0 w/s 48.0 + 26.0 = 74.0 141.0 Very different So read data matches and write data diverges Which numbers should I go with? The physical devices or the logical device? Thanks David Goldsmith

OK, here on the general Centos list, I have one more thing to add to the above: I was chatting on the epel list about it, didn't get a lot of help (no reflection on those there) but smooge said he might have time to look into it next week. Also, someone else from the centos list sent private email that he had had the same problem and thought it might be a caja problem, but had not gone any further than that. So, I opened a terminal and started caja. Voila! not only did a caja window open, but the desktop icons appeared, and the right-click menu. however when I closed the terminal it all went away. :( so I did ALT-F2 and typed in "caja", hit enter, and there's the full desktop again. and this time it stayed. from these symptoms I don't think I can tell if it's a caja problem, or an issue with whoever starts up caja after login (something in systemd ???) > > Jim Perrin > > The CentOS Project | http://www.centos.org > > twitter: @BitIntegrity | GPG Key: FA09AD77 -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ---------------------------- Do you not know?

SELinux context for web application directories
by James B. Byrne 29 Jun '14

29 Jun '14

CentOS-6.5 We deploy web applications written with the Ruby on Rails framework using Capistrano (2.x). Each 'family' of web applications are 'owned' by a dedicated user id. The present httpd service is Apache 2.2.15 and we use Passenger 3.0.11. We are moving shortly to a new deployment host and at that time we will be updating to Apache 2.4.9 and Passenger 4..0.25. Our deployment practice is to place the 'family' directory under /var/data/. This is the home directory of the application user id. We place each individual web application or component into its own directory underneath the family root. So that things look like this: /var/data/hll_th ├── backups │ └── pgsql ├── etc │ └── database.yml ├── hll_th_cc_edi_get │ ├── current -> /var/data/hll_th/hll_th_forex_rss/releases/20140519201615 │ ├── releases │ └── shared ├── hll_th_forex_rss │ ├── current -> /var/data/hll_th/hll_th_forex_rss/releases/20131204193652 │ ├── releases │ └── shared ├── hll_th_hp3000_billing │ ├── current -> /var/data/hll_th/hll_th_forex_rss/releases/20140214211431 │ ├── releases │ └── shared ├── log ├── lost+found └── pgpass -> .pgpass The questions I have are: What is an appropriate SELinux context for such a directory structure given it is used by a httpd service? Is the default user home setting of system_u:object_r:home_root_t acceptable? Is system_u:object_r:httpd_sys_content_t preferable instead? is some other SELinux context preferred for RoR web applications using Apache with mod-passenger? -- *** E-Mail is NOT a SECURE channel *** James B.

Karanbir, PLEASE! You've never responded to my question about whitelisting. That asinine nixspam did it to me again, and this time... seriously, I urge you, personally, to go there and try to remove a site. They've "enhanced their security", that is, mangling the capchas, to the point that it took me about five minutes or more, and about a dozen or 15 challenges, before I got one that I could read well enough to copy into the "I'm human" field. This is *really* impossible now. Oh, and the audio challenge is a very bad joke. *YOU* try to figure out what it says.... mark, frustrated
