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

Not sure if this got through - nixspam was being aggravating, so I'm reposting. James B.

Use semanage fcontext (and the manpage example is what I use all the time), followed by a restorecon -Rv mark

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

Actually I think I was wrong... Somehow the mail is landing on my box (from an address I am not blocking) and this particular email is requesting going OUT of my box. Seems the firewall operating fine. I just looked at it incorrectly. Jerry

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
