SSH server

This guide will show you how to whitelist your GoodAccess IP address in SSH server.

Step 1

To whitelist the IP, open /etc/hosts.allow file, enter GoodAccess Gateway IP/32, and Save the file.

sshd: 21.22.23.24/32, 33.34.35.36/32

This line will allow all the comma separated IP blocks to your SSH port

Step 2

To block access from all other sources, open /etc/hosts.deny file, enter "ALL", and Save the file.

sshd: ALL

Note: There are several other ways to restrict access to SSH servers like IPTABLES firewall (restrict the access to TCP port 22), or SSH daemon config.
