To use this script you only need the packages File::Path and Getopt::Long; both of them are already on newer distros, just put the script somewhere in your bin path, I have it in /usr/local/bin and call it with sudo.https://ivanvillareal.com/ubuntu-9-10-on-an-hp-mini-110-1125nr/Wed, 27 Jan 2010 00:56:14 +0000https://ivanvillareal.com/ubuntu-9-10-on-an-hp-mini-110-1125nr/I got this new mini 110, it came with Windows 7 Starter, and after a day of using it I was very frustrated because it was very limited, for example, I was unable to change my Desktop background, the network management is confusing and frustrating, and it had a lot of crapware, except for the hp games which some of them are fun. Anyway, right now I don’t have time to spend getting a new OS on this machine, I just want something that works, I don’t plan using this to work, but I would like to have some of the tools I use into this.https://ivanvillareal.com/mount-a-remote-filesystem-using-sshfs/Wed, 09 Dec 2009 19:25:39 +0000https://ivanvillareal.com/mount-a-remote-filesystem-using-sshfs/I often have to upload files to several servers, and some of them doesn’t have an rsync or ftp server, so if I’m going to make a deployment, I have to use scp, or sftp to upload the files. This works well when I need to make a quick change or test 1 file, but If I have to synchronize several files it is a very time consuming task. So what I use in this cases is sshfs it is a pretty cool tool, to allow me to mount any filesystem so I can use any rsync on a remote server without dealing with opening ports configure, the server or do other stuff,https://ivanvillareal.com/mysql5-and-php5-on-centos4/Mon, 12 Oct 2009 19:00:06 +0000https://ivanvillareal.com/mysql5-and-php5-on-centos4/I have the need to install php5 and mysql 5 on a centos 4 server, so I found that the Centos Plus repository had this, and this is what I did to get these two working. First check what is the version of the distro: cat /etc/*release* Then make an update: yum update After 496 package updates I’ve installed php5 yum --enablerepo=centosplus install php This were the installed packages:https://ivanvillareal.com/removing-hybrid-feature-of-an-acomdata-drive/Thu, 01 Oct 2009 17:58:28 +0000https://ivanvillareal.com/removing-hybrid-feature-of-an-acomdata-drive/About 2 years ago I purchased this 500Gb Acomdata drive that was on sale at Fry’s, it was a good deal back then, cost me about 100 bucks, it had an aluminium case and a power off switch, and I was in the need to expand the storage capacity of my multimedia server, which is linux based. I didn’t researched this product, I didn’t even knew that acomdata was a brand, anyway I remember seeing the “Hybrid Drive” statement, but didn’t care, I was going to wipe this drive an reformat it as ext3, so I was aware that all the “software features” it had were useless to me, like the PushButton™ Backup and the Nomad Mobile Desktop.https://ivanvillareal.com/setting-up-ssh-keys-for-passwordless-login/Fri, 25 Sep 2009 23:57:29 +0000https://ivanvillareal.com/setting-up-ssh-keys-for-passwordless-login/Most part of the time I spent on my development machine I have several terminals opened, but thanks to screen I only have one per server. However I’m constantly in the need to login to some servers just to make a quick check of something, so I have to type in my credentials every time I log in, this really annoys me, because when I’m focused on something I don’t want to loose that focus waiting for the login prompt.https://ivanvillareal.com/automated-capture-of-webpages-main-process/Fri, 25 Sep 2009 00:21:45 +0000https://ivanvillareal.com/automated-capture-of-webpages-main-process/This post is the continuation of Xvfb and Firefox headless screenshot generator where I explained how Xvfb and Firefox can be used to get a screenshot of any web resource supported by firefox. The next challenge I had, involved the creation of an automated process that could be called from the web or from a cron job, this process job would take a list of sites that need to be captured, and it will save its shots with their respective thumbnail somewhere, also this same process had to communicate somehow with the front end, to inform the user about the status.https://ivanvillareal.com/xvfb-and-firefox-headles-screenshot-generator/Fri, 18 Sep 2009 00:25:41 +0000https://ivanvillareal.com/xvfb-and-firefox-headles-screenshot-generator/I’ve been working on a project that its main purpose is to get a screenshot of a bunch of different sites. The requirements for this project were simple. It has to be fast It needs to run on linux I did some research, trying to found the best approach, I already knew Xvfb but haven’t worked with it in a real project, there wasn’t much info about what I was trying to do, however I’ve found some other automated solutions made in .
