A few weeks ago I wrote a article on disabling the caps lock key in Windows.  I decided since I have been writing some Linux articles I may as well show a way to do the same thing in Linux. Its a short, quick fix but it can be useful if you hate capslock like I do.

Below I outline the steps to disable the key:

I recently had to do a install of VMWare server with 4 guest operating systems and once I got it all going I found that the arrow keys were not working. On some hosts they were mapped to control or shift and on the other hosts they just did not work. After a little searching I found a simple solution. Below I outline how to fix this small issue.

When I first was working with an Amazon Web Services instance at EC2 I was getting frustrated trying to use SecureCRT to connect to the AWS instance.

When configuring SSH keys to be able to login to a server without a password you mighkeys2t run into a permissions error. If the authorized_keys or authorized_keys2 file has the incorrect permissions it will not authenticate with your ssh-rsa key but instead still require a password. If you are having trouble configuring SSH keys you should check the /var/log/secure file to see if there is an error displaying in that log. You may see the error displayed below.

Error: Authentication refused: bad ownership or modes for file .ssh/authorized_keys

If you see this error it means that the authorized_keys or authorized_keys2 file has the incorrect ownership or permissions. Make sure that the authorized_keys file is owned by the user that will be logged into and the permissions are 600.

The easiest way to send encrypted email with Gmail that I have found is to do so with Firefox and the FireGPG plugin.

Below are a few simple steps that should help encrypt email you are sending through Gmail to someone who has a PGP key.

NOTE:The below steps are if the FireGPG buttons are not showing in Gmail and is a temporary fix until FireGPG is updated and the entire message can be encrypted. I will update this with a link to the new article/howto once FireGPG is updated.
