cfengine vs. puppet
by Ski Dawg 28 Aug '10

28 Aug '10

Hello All, I have been tasked with getting some configuration management system running at work. We have about 20 web servers running (some virtual and some physical), and we are trying to come up with a tool that will assist setting up new boxes as we bring them online, as well as maintaining existing systems when changes are necessary. After spending a little bit of time searching around today, I have run across 2 that seem like good options, cfengine and puppet. Does anyone have any thoughts about either of these tools? Is there definite advantage to using one over the other from your experience? Is there a another tool that I should be evaluating? -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Never trust a computer you can't throw out a window. -- Steve Wozniak

[OT] Label Printer Recommendations
by Colin Coles 28 Aug '10

28 Aug '10

Greetings Folks, I am after any recommendations or experiences using Label printers to print barcodes with CentOS, we currently using Star TSP700's but they're not clear enough for the scanners we have. There seems to be plenty of choice but not much Linux support going on, 'Never had anyone ask for Linux drivers before..' seems to be the most common answer when trying to buy. I have also tried a Brother P-Touch QL-550 but can't seem to get that to print at all using the Foomatic drivers available online. TIA Colin.

Re: [CentOS] phpMyAdmin can't connect to remote server
by Brian Marshall 27 Aug '10

27 Aug '10

Hi All, I have had a thread about this going on the phpMyAdmin list for a little while. Nobody there has been able to shed any light on my problem. It seems that with phpMyAdmin I can not connect to remote servers. Though it also seems that apache, php and mysqli all work fine outside of phpMyAdmin. Below I have detailed my trouble shooting. This only seems to be an issue for me with CentOS 5 so I'm hoping someone out there has run into this before. I'm certain there is some setting or dependency I am missing so if you have any insight into this I'd greatly appreciate it. We have CentOS 5.5 production systems with a major Cloud VM vendor and I have replicated the results with CentOS 5.5 on local VM's (ISO install) with my own VM platform. The remote database server is listening on eth1. eth0 is our public routable IP and eth1 is our 10.x.x.x private subnet. We do not expose the mysql servers on the public interfaces. All of our web applications access the database servers by IP on the 10.x.x.x subnet on eth1. The apache server where phpmyadmin is installed also has other virtual hosts that have wordpress instances among other things, that use the mysqli interface to connect to the same remote database server and they all work fine. The apache server also has a local mysql server that I can successfully connect phpmyadmin to using localhost or 127.0.0.1 for the db host name with cookie authentication. The apache server where phpmyadmin is installed I can use the bash mysql client and connect to the remote database server with my credentials. I have tested CentOS 5.5 with RPM installed httpd and RPM installed PHP 5.1 and PMA 2.x, and CentOS 5.5 RPM installed Apache, my compiled PHP 5.2.3 and PMA 3.x. Both with the same result. Logins to any remote server over TCP with cookie auth fail with a "#1045 Cannot log in to the MySQL server" and tcpdump shows no packets on the interface to the DB server. Connections to the local database server via PMA 3.x, my compiled php 5.2 over tcp using localhost, port 3306, cookie auth connects right away. Connections to the local database server via PMA "mysqli://localhost:3306" shows no traffic in tcpdump on lo, eth0 or eth1 so I'm assuming it uses the local socket for this. I have tested Ubuntu 10 with Apt installed php, apache, mysqladmin and it all works out of the box. I would love to just throw ubuntu up there but work won't allow a mixed linux environment. It HAS to be CentOS. Just to make sure I am not crazy I made the test file below and connected to my remote database from the same virtualhost as phpmyadmin using the same username and password (not root). It works perfectly and I get the results from my mysql.user table. I have tested this php both from the CLI and through Apache. <?php $mysqli = new mysqli('10.x.x.x.', 'myuser', 'mypass', 'mysql'); $result = $mysqli->query( 'SELECT * from user'); while( $row = $result->fetch_assoc() ){ print_r($row); echo "\n"; } $result->close(); $mysqli->close(); ?> And my PMA config files look like this THIS DOES NOT WORK <?php /* * Generated configuration file * Generated by: phpMyAdmin 3.3.5 setup script by Piotr Przybylski <piotrprz(a)gmail.com> * Date: Thu, 26 Aug 2010 10:32:53 -0600 */ /* Servers configuration */ $i = 0; /* Server: glacier [1] */ $i++; $cfg['Servers'][$i]['auth_type'] = 'cookie'; $cfg['Servers'][$i]['host'] = '10.x.x.x'; $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark'; $cfg['Servers'][$i]['relation'] = 'pma_relation'; $cfg['Servers'][$i]['table_info'] = 'pma_table_info'; $cfg['Servers'][$i]['table_coords'] = 'pma_table_coords'; $cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages'; $cfg['Servers'][$i]['column_info'] = 'pma_column_info'; $cfg['Servers'][$i]['history'] = 'pma_history'; $cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords'; $cfg['Servers'][$i]['verbose'] = 'somename'; $cfg['Servers'][$i]['port'] = 3306; $cfg['Servers'][$i]['socket'] = ''; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['user'] = ''; $cfg['Servers'][$i]['password'] = ''; $cfg['Servers'][$i]['AllowRoot'] = false; $cfg['Servers'][$i]['AllowDeny'] = array ( 'order' => 'allow,deny', ); /* End of servers configuration */ $cfg['blowfish_secret'] = '4c74332d81b5c0.29678885'; $cfg['UploadDir'] = ''; $cfg['SaveDir'] = ''; $cfg['DefaultLang'] = 'en-utf-8'; $cfg['ServerDefault'] = 1; $cfg['ForceSSL'] = true; $cfg['AllowAnywhereRecoding'] = true; $cfg['UseDbSearch'] = false; $cfg['ShowPhpInfo'] = true; $cfg['LeftDisplayServers'] = true; $cfg['DisplayServersList'] = true; ?> THIS WORKS <?php /* * Generated configuration file * Generated by: phpMyAdmin 3.3.5 setup script by Piotr Przybylski <piotrprz(a)gmail.com> * Date: Thu, 26 Aug 2010 10:34:31 -0600 */ /* Servers configuration */ $i = 0; /* Server: localhost [1] */ $i++; $cfg['Servers'][$i]['verbose'] = 'localhost'; $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['port'] = 3306; $cfg['Servers'][$i]['socket'] = ''; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['extension'] = 'mysqli'; $cfg['Servers'][$i]['auth_type'] = 'cookie'; $cfg['Servers'][$i]['user'] = ''; $cfg['Servers'][$i]['password'] = ''; /* End of servers configuration */ $cfg['UploadDir'] = ''; $cfg['SaveDir'] = ''; $cfg['ForceSSL'] = true; $cfg['blowfish_secret'] = '0(s3$9dea5bfy7ic8wo4l8kn&is3ANFY6NA*CM64'; $cfg['MaxRows'] = 100; $cfg['DefaultLang'] = 'en-utf-8'; $cfg['ServerDefault'] = 1; ?> All that being said it looks like PHPMyAdmin does not run on CentOS (It feels crazy just to say that). I know there's something I'm missing. If anyone else has any insight or questions please let me know. I'm happy to experiment.

ATI, Catalyst and a new kernel
by Robert 27 Aug '10

27 Aug '10

Please bear with me for a really stupid question... I have a Radeon HD 4550 video card and currently run the Catalyst driver, fglrx_6_9_0-8.741-1. I use the "package managed" method for installing, allowing me keep track of what's what: [rj@madeleine ~]$ su Password: [root@madeleine rj]# grep fglrx /var/log/yum* /var/log/yum.log:May 20 12:37:07 Updated: fglrx_6_9_0-8.723-1.i386 /var/log/yum.log:Jul 25 13:04:49 Erased: fglrx_6_9_0 /var/log/yum.log:Jul 25 13:33:11 Installed: fglrx_6_9_0-8.741-1.i386 [root@madeleine rj]# exit exit [rj@madeleine ~]$ So, my question is, must/should I rebuild the driver each time I install an updated kernel or is it sufficient to "yum remove fglrx_6_9_0-8.741-1", update the kernel and (maybe) glibc, then "yum localinstall $(locate i386/fglrx_6_9_0-8.741-1.i386.rpm)" ? If anyone wonders why I don't simply stick with the generic driver, the fglrx driver makes a WORLD of difference with Googleearth. Thanks!

Hi folks, Anyone know the whereabouts of libgtkembedmoz.so()(64bit) as it is needed by miro-1.0-1.el5.rf.x86_64 (rpmforge) I tried a whatprovides and have looked at epel as well as rpmforge - no luck.

Backing up pass words
by Todd Cary 26 Aug '10

26 Aug '10

I am currently running CentOS 4 and want to install CentOS 5. To do that, I plan to install a new HD in my server box onto which CentOS will be installed. I will then copy the "home" directory from the old drive or from a backup on a USB drive, however I am not sure how to handle the Users/Passwords from the old installation. Many thanks...

Set default file/dir permissions?
by Tim Nelson 26 Aug '10

26 Aug '10

Greetings all- I have a system running CentOS 5.5 x86_64. It's serving NFS for several 'frontend' boxes in a web application setup. All data is stored in specific dir but written by different users. When the webapp attempts to read this information, it may or may not have permissions to this data. What I'd like to do is set 'default permissions' on the data storage directory (lets call this /var/appdata) so that any file or directory created under this is assigned a default set of permissions, and if possible, ownership. I've looked at and tested umask but it only seems to allow/disallow specific permissions, not force permissions. Am I missing something? How can I force all files/dirs created under a specific directory to have the permissions (and ownership if possible) that I specify? Thanks! Tim Nelson Systems/Network Support Rockbochs Inc.
