About SSH Keys SSH keys provide a more secure way of logging into a Ubiquiti AirOS device with SSH than using a password alone. While a password can eventually be cracked with a brute force attack, SSH keys are nearly impossible to decipher by brute force alone. Generating a key pair provides you with two long string of characters: a public and a private key. You can place the public key on any server, and then unlock it by connecting to it with a client that already has the private key. When the two match up, the system unlocks without the need for a password. You can increase security even more by protecting the private key with a passphrase. Step One—Create the RSA Key Pair The first step is to create the key pair on the Aircontrol Server machine (OR it be your computer): ssh-keygen -t rsa

When making an SSH connection to a machine we've never contacted before, The server presented its host key to the client as part of the initial handshake. On Client when you said 'yes', SSH client saves the server's host key locally in the file $HOME/.ssh/known_hosts. for root user location is /root/.ssh/known_hosts.This file is, effectively, your personal Certificate Authority -- it is the list of all SSH server The next time you connect to this machine, your SSH client will go through the standard steps of verifying the remote machine and allowing you to log in, this time, it did not ask you to verify the key fingerprint at all. That's because the key was in your $HOME/.ssh/known_hosts file. The SSH client actually checks in a few places: The global known hosts file, typically /etc/ssh/ssh_known_hosts.

There are so many factors a computer geek needs to know. We need to know everything from hardware to software to freeware to groupware — and believe in me, that is not an easy thing. One of the factors that can actually make a computer geek feel dumbfounded are those pc slots at the back of a desktop computer PC. At some point, I’ve always horrible at least twice or three times and puzzled one slot to the other. So, I explored far and wide to find this! Not only does this include slots, but it also features different kinds of RAM, CPU sockets, peripheral cards, power connectors, desktop card slots, hard drive types and processor card sockets and slots. It’s a great source to carry around. I, myself, have one on my phone in case I need it — and I think pc geeks need to know, or at least get familiar themselves, to these elements.

Are you having problems with your tab key in Windows 7? I know I am! My desktop machine runs Windows 7 64-bit and has been working fine for a months until a few days ago. Suddenly, the tab key would not move me to the next form field in an online form. I though it was odd, so I restarted the browser and it worked once, but then stopped randomly a little while later. I thought it was isolated to the browser, but quickly realized I was having the same tab issue in Word, Outlook and Quickbooks. What a royal pain! I didn’t realize how much I used the tab key until it stopped working! Anyway, after doing some research and messing around with stuff, I figured out what the problem was. In this article, I’ll try to write out the different possible solutions and hopefully your tab key will start functioning properly again. I quickly managed to rule out hardware issues like the keyboard because I switched the keyboard and still had the same problem. This issue is normally a software issue a...
