LINUX HOWTO: Limiting SSH access to specific IP addresses

Intro:

This is a simple way to permit a select few IP addresses to access your raspberry pi though SSH and deny any others. By white listing certain IP addresses from networks you know you are adding a layer of security helping prevent others from accessing your machine. This is handy if you only access your machine from a few set locations, such as on the LAN and at work.

There are a few methods you could go about doing this, but i find this the most easy to implement, allowing you do accomplish basic permit and deny without iptables.

The two files needed to be edited are /etc/hosts.allow and /etc/hosts.deny

Step 1) 

Enter:
sudo nano /etc/hosts.allow

The file should be empty. At this point just add the ip addresses or subnets which you want to permit, for example:

sshd: 10.0.0.0/255.255.255.0 

sshd: 192.168.0.0/255.255.255.0

TIP: For specific IP addresses, just enter the address without the subnet.

Step 2)

Enter:

sudo nano /etc/hosts.deny

By entering the following you will deny all other addresses which were not explicitly defined before (everyone else).

sshd: ALL

Conclusion:

Now only those ip addresses or subnets defined will be able to get ssh access to your ssh server, others will not be able to connect.

LINUX HOWTO: Adding SSH login messages

This will display a message to those who connect to you ssh server before logging on.

Steps:

sudo nano /etc/ssh/sshd_config
- Open this file in terminal. Then find the line "#Banner /etc/issue.net" and remove comment so that it reads "Banner /etc/issue.net". Then save.

sudo nano /etc/issue.net
- Secondly open this file and enter your message in this file, then save. ASCII looks good here.


sudo service ssh restart
- Restart ssh, and then the message will be displayed to users.

LINUX FIX: Gigabyte 990X - USB 3.0, 2.0 and Ethernet disabled after Ubuntu install.

After installing Ubuntu on my new computer I realised that only two of my USB 2.0 ports were working an non of the USB 3.0 ports or Ethernet network card. This seems to be a problem with many similar Gigabyte boards to mine. However there is a quick easy (revealingly so) solution to this.

In terminal run the following command: sudo nano /etc/default/grub
Find the line GRUB_CMDLINE_LINUX="" and replace with GRUB_CMDLINE_LINUX="iommu=soft"
save the file
open up another terminal and run: sudo update-grub
exit and restart computer

After applying this, every port; both 3.0, 2.0 and ethernet should work perfectly.

FIX: Getting the R.A.T. 3 mouse to work on Ubuntu

This is a problem I am faced with every time I install Ubuntu and want yo use my R.A.T. 3 mouse. I found a solution though googling and it linked me to this youtube video.

In the description is a simple guide, so you don’t have to watch the video. I have included in the post bellow.

First type in the command to find out which product you have:

xinput -list

Once you find out what mouse you have:

sudo gedit /etc/X11/xorg.conf

For me I have the Madcatz Mad Catz R.A.T.3; type in:

Section "InputClass"
Identifier "Mouse Remap"
MatchProduct "Madcatz Mad Catz R.A.T.3 Mouse"
MatchDevicePath "/dev/input/event*"
Option "ButtonMapping" "1 2 3 4 5 0 0 8 9 0 0 0 0 0"
EndSection

For Madcatz Saitek Cyborg R.A.T.3; type in:

Section "InputClass"
Identifier "Mouse Remap"
MatchProduct "Saitek Cyborg R.A.T.3 Mouse"
MatchDevicePath "/dev/input/event*"
Option "ButtonMapping" "1 2 3 4 5 0 0 8 9 0 0 0 13 14"
EndSection

Enjoy.
