SSH Servers Clients and Keys - More about it now

This article covers important information about SSH Servers, Clients and Keys. Use SSH keys for authentication when you are connecting to your server, or even between your servers.

They can greatly simplify and increase the security of your login process. 

When keys are implemented correctly they provide a secure, fast, and easy way of accessing your cloud server.


Turn off password authentication Linux:

With SSH key authentication configured and tested, you can disable password authentication for SSH all together to prevent brute-forcing. When logged in to your cloud server.

1. Open the SSH configuration file with the following command.

$ sudo nano /etc/ssh/sshd_config

2. Set the password authentication to no to disable clear text passwords.

PasswordAuthentication no

3. Check that public key authentication is enabled, just to be safe and not get locked out from your server. If you do find yourself unable to log in with SSH, you can always use the Web terminal control panel.

PubkeyAuthentication yes

Then save and exit the editor.

4. Restart the SSH service to apply the changes by using the command below.

$ sudo systemctl restart sshd

With that done your cloud server is now another step along towards security. 

Malicious attempts to connect to your server will results in authentication rejection, as plain passwords are not allowed, and brute-forcing an RSA key is practically impossible.

Troubleshooting DHCP client issues

This article will guide you on troubleshooting different DHCP #client issues. Whenever a DHCP server gets a request from a client it responds with a DHCP offer containing IP address being offered, #network mask offered, the amount of time that the client can use and keep it, the ip address of the DHCP server making this offer.

To #Troubleshoot DHCP:

1. Check for IP Address Conflicts. #DHCP clients connect to the network using a leased IP address.

2. Check Physical Connectivity.

3. Test connections with other Client using a Static #IP Address.

4. Confirm Switch #Port #Configuration.

5. Verify the source of Clients IP Address.
