Security support for Debian GNU/Linux 5.0 (code name "lenny") will end 2/6/2012.  If you are still using Lenny, you should run a distribution update to Squeeze in the next 60 days. The Debian project released Debian GNU/Linux 6.0 alias "squeeze" on the 6th of February 2011. Users and distributors have been given a one-year timeframe to upgrade their old installations to the current stable release. Hence, the security support for the old release of 5.0 is going to end on the 6th of February 2012 as ... ]]> http://albertech.net/2011/12/debian-lenny-eol-262012/feed/ 0 http://albertech.net/2011/11/modifying-awstats-to-show-total-hits-for-matching-files/ http://albertech.net/2011/11/modifying-awstats-to-show-total-hits-for-matching-files/#comments Thu, 03 Nov 2011 18:22:43 +0000 admin http://albertech.net/?p=829 Here's a quick modification to the awstats file that allows you to add a totals field for the "Viewed - Full List" option. There isn't a total hits field for matching files in awstats, so I added one to make it more useful. This makes it a lot quicker to total up hits for a specific folder, file type, or specific file in awstats. ]]> http://albertech.net/2011/11/modifying-awstats-to-show-total-hits-for-matching-files/feed/ 1 http://albertech.net/2011/10/upgrading-debian-lenny-to-squeeze-with-mysql-for-row-based-replication/ http://albertech.net/2011/10/upgrading-debian-lenny-to-squeeze-with-mysql-for-row-based-replication/#comments Fri, 28 Oct 2011 22:46:56 +0000 admin http://albertech.net/?p=820
I completed an upgrade of Debian Lenny to Squeeze on a production database server over the weekend. It went quite well and I had zero downtime thanks to my secondary database servers running in-place. One of the biggest benefits to running Squeeze is that MySQL runs at version 5.1.49. Lenny only supports up to MySQL 5.0. Row-based-replication is safer to replicate data to other servers since all changes are replicated. Prior to MySQL 5.1.14, updates to the mySQL database were not replicated. They were updated via statements (e.g. GRANT, REVOKE). This can potentially cause data-consistency between the master and ... ]]> http://albertech.net/2011/10/upgrading-debian-lenny-to-squeeze-with-mysql-for-row-based-replication/feed/ 1 http://albertech.net/2011/10/iphone-4s-tracking-information/ http://albertech.net/2011/10/iphone-4s-tracking-information/#comments Wed, 12 Oct 2011 22:45:47 +0000 admin http://albertech.net/?p=809 ]]> http://albertech.net/2011/10/iphone-4s-tracking-information/feed/ 0 http://albertech.net/2011/10/guide-for-using-php-curl-with-https-requests-and-ca-certificate/ http://albertech.net/2011/10/guide-for-using-php-curl-with-https-requests-and-ca-certificate/#comments Wed, 05 Oct 2011 23:30:11 +0000 admin http://albertech.net/?p=790 I've looked at a number of cURL PHP tutorials on the web and noticed "curl_setopt($RESTsession, CURLOPT_SSL_VERIFYPEER, false);" is often used for accessing secure websites via cURL. This is often seen when people ask "I cannot connect to HTTPS site using cURL" or have the "SSL certificate problem, verify that the CA cert is OK" error with cURL. Ideally, you should set the SSL_VERIFYPEER value to true unless the server you are connecting to does not have a signed certificate. If you are sending confidential data, wouldn't you want to make sure you are connecting to the correct server? This guide will help you get the CA certificate from the remote server using Mozilla Firefox 6 and then use PHP with cURL to retrieve the information from the remote https server.]]> http://albertech.net/2011/10/guide-for-using-php-curl-with-https-requests-and-ca-certificate/feed/ 2 http://albertech.net/2011/09/kernel-org-still-down-fix-apt-source/ http://albertech.net/2011/09/kernel-org-still-down-fix-apt-source/#comments Wed, 21 Sep 2011 20:45:31 +0000 admin http://albertech.net/?p=788 mirrors.kernel.org on your Linux apt sources so you can continue to get the latest updates.
