Practitioner Level

Managing SSH Access

30 minutes

2 Learning Objectives

In this lab, we will restrict SSH access to specific user accounts from specific sources. This will allow us to granularly control SSH access to a host.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Allow Susan SSH access from host susan-ws.office21.net

Edit the /etc/ssh/sshd_config file with the following line:
```
sudo vi /etc/ssh/sshd_config
```
- enter password for cloud_user
```
AllowUsers Susan@susan-ws.office21.net  
```

Permit root SSH login from the subnet 10.0.1.0/24

The first step is to permit root logins by removing the comment in front of the line #PermitRootLogin yes in the /etc/ssh/sshd_conf file.
Secondly, we need to add root@10.0.1.0/24 to the AllowUsers line in the /etc/ssh/sshd_config file.
Now we need to restart the sshd service so the changes we made will take affect:
```
systemctl restart sshd  
```
