I will guide you trough the installation and configuration of the following software: Ubuntu 14.10 Gnome 3.14 VNC 4.1.1 Important Notes: This procedure is only applicable to a new installed Ubuntu Linux OS, if you have existing running Ubuntu Linux with a different version where you like to install a desktop and vnc, i suggest you make a backup of your system and after that, you may proceed with this procedure.

Copy/Transfer Files Between Two Linux Servers Using SCP | John Veldboom The other day we ran into a good problem that our site has grown and we are in need of a new server. So we ordered the server and now we need to transfer all the files from the old server to the new one. But rather than downloading all the files to our local machines then re-cuploading them to the new server, we're going to show you how you can skip the middle man and transfer files from server to server. The only requirements is that you need to have SSH access to both servers. We're going to be using the Linux command scp which stands for secure copy. We're going to be using the following options: r = recursively copy entire directories C = compression enable p = preserves modification times, access times, and modes from the original file Also, if you're going to transfer a lot of data between the webservers, you probably want to add the nohup command too. nohup runs a command even if the session is disconnected or the user logs out. Hope this helps someone as much as it did me today.

Service names The service command references a service using its init script, stored in the /etc/init.d directory. Some names vary depending on your distribution - apache is 'httpd' on CentOS, for exampe, while it's 'apache2' on Ubuntu. Service status The following example shows how to check the status of httpd on CentOS using the service command. $ sudo service httpd status httpd is stopped Service control If a service isn’t running you can use service to start it. $ sudo service httpd start Starting httpd: [ OK ] If the application cannot be started the service command will report the failure and usually show a message explaining the reason. netstat In the example above httpd cannot be started because something is already listening on the port.

How to block Chrome from running in the background For the past week or so I have been noticing that various versions of Google Chrome started to add icons to the Windows system tray. I first noticed it in Google Chrome Canary, and since yesterday in Chrome Beta as well. The icons and the browser's behavior is not the same right now, which is certainly puzzling. Note that Google is displaying those notifications for quite some time now in various editions of the browser, but that you do not really see the icon until you enable at least one application to show them in the browser. The Canary notification on the other hand is a new thing. In Chrome Beta, you will notice that Chrome remains open even if you close the browser explicitly on the system. The easiest way to disable that is to uncheck the "Let Google Chrome run in the background" setting in the context menu. You can alternatively open the settings in the browser and search for background there. This takes care of this version of the browser.

HOW TO FIX ""The requested URL /phpMyAdmin was not found on this server."" thanks for the help. worked great. I have to say that what I have to do first was to edit the file /etc/phpmyadmin/apache.config in the bottom part of the doc there is this: # Authorize for setup <Directory /usr/share/phpmyadmin/setup> <IfModule mod_authn_file.c> AuthType Basic AuthName "phpMyAdmin Setup" AuthUserFile /etc/phpmyadmin/htpasswd.setup </IfModule> Require valid-user </Directory> # Disallow web access to directories that don't need it <Directory /usr/share/phpmyadmin/libraries> Order Deny,Allow Require valid-user--------------------here there was as Deny from All--------------- </Directory> <Directory /usr/share/phpmyadmin/setup/lib> Order Deny,Allow Require valid-user--------------------same as above-------------------------------- </Directory> with this change when I access the localhost/phpmyadmin it prompts a username password field that was setup at the phpadmin install process. thanks again!!!
