Linux – Write Access to USB Thumb Drive

Make sure that your USB thumb drive is formatted in FAT or FAT32. Write support for NTFS is still on experimental stage since M$ refuses to release specification of NTFS.

Thanks to ubuntuforums for this information.

Linux – Ext FS in Windows

By default, windows cannot read Linux volumes. What if you need to restore some of the files on a linux box and you only have Windows on your area? There are free software where you can have full access to Linux volumes (ext2 and ext3).  You may try downloading Ext2 IFS for Windows or Explore2fs.

MySQL – Moving Out

Evaluating system is a very tough work. Now, from the test web server, I need to move the system to a much higher model of machine. I need to copy Web Pages, and Database. For example, I need to move WordPress to new machine. I use the following guide:

Make sure that you can connect to new Linux machine especially in MySQL, I use the article posted on cyberciti.biz about How do I enable remote access to MySQL server.

Next sted is to copy the database to new machine. I use the article from mysql about Copy MySQL Database to other Machine.

After the database, copy the webpage using the rsync command. I use the article from Ubuntu dapper’s ubuntuguide.org website about How to copy files/folders from local machine into remote Ubuntu machine (rsync).

Lastly, you need to modify database settings so you may able to connect to your MySQL database.

Linux Commands

Here are some common linux commands that I use to install and manage may Linux machine:

Assigning root password – sudo passwd root

Checking partition size – sudo df -h

Checking folder size – sudo du – hs <folderpath> / sudo du -chks (summary)

Change File and Folder permission – sudo chmod 777 /var/www/smf -R

Copy File – sudo cp -R <source> <destination>
Remove File – sudo rm <file>

Create Directory – sudo mkdir <directoryname>

Copy file to remote machine – rsync -v -u -a -r –delete –rsh=ssh /var/www/ root@remotehost:/var/www/
Others will be posted on this page regularly…

WordPress Support – PHPMailer

By default, WordPress uses PHP mail function to send emails for Forget password module (see details on the link).

WordPress Support – Slow Login

I just noticed one time that I want to post new item on my wordpress blog site, it takes me 1 minutes and 30 seconds before loging-in to my site. Luckily I found a solution from wordpress support that I need to remove some lines on the index.php of wp-admin folder.

---

It’s the RSS feeds it tries to pull in. Edit the index.php file in wp-admin, and change all the three lines that start:$rss = @fetch_rss(…

To be:

$rss = “”;

Kudos to WordPress Support especially to brianthewise!

Windows to Linux

I have been working on for Windows applications for about 8 years and finally decided to use Open Source on my workplace. At first I use Linux thru Ubuntu and found it very easy to use and learn, thanks to their online forums and community.
