After creating a group the privileges can be added by editing the group. Go toand click on the edit symbol (pencil) right next to the group you like to change.
To assign privileges, just click on the pencil icon on the right of Assigned Privileges. A form will be shown where each page can be either selected or deselected.
The search bottom at the top of this form can be used to quickly find the right page.
After making the right selection click on Save to store the new settings.
SSH and console login¶
User accounts can be used for logging in to the web frontend, as well as for logging in to the console (via VGA,
serial or SSH). The latter will only work if the user’s shell is not set to
/sbin/nologin and if group the user is
part of is allowed SSH access.
In order to access OPNsense via SSH, SSH access will need to be configured via. Under the “Secure Shell” heading, the following options are available:
|Enable secure shell||Global on/off switch.|
|Login Group||Which user groups can access OPNsense via SSH.|
|Permit root user login||Normally, only non-root accounts are allowed for security reasons. This option enables root login.|
|Permit password login||The recommended login method is using SSH keys as it’s more secure, but this option will also enable password logins.|
|SSH Port||Defaults to 22, but can be changed to make port scanning less effective.|
|Listen interfaces||By default, SSH listens on all interfaces. You can limit this (to just the LAN, for example) for additional security at the cost of availability.|
