Fix Common Issues While Connecting to Snapshooter

Sometimes, you will face some issues while connecting your server to Snapshooter. This section will show you some common issues and how to fix them.

1. Firewall Issue Adding Correct IP Address

If you have set up a firewall on your server, restricting SSH access to your server using the IP allow/block list. Then, you will need to add the following IP addresses to your firewall whitelist.

• 46.51.158.3

• 54.228.167.152

• 54.72.152.22

If you are using Ubuntu and Debian-based server operating system, then the UFW is the default firewall. In this case, you will need to add the following rules to whitelist the above-listed IP addresses.

ufw allow from 46.51.158.3 to any port ssh
ufw allow from 54.228.167.152 to any port ssh
ufw allow from 54.72.152.22 to any port ssh

If you are using RHEL, Fedora, CentOS, Rocky Linux, and Alma Linux-based server operating system, then the Firewalld is the default firewall. In this case, you will need to add the following rules to whitelist the above-listed IP addresses.

firewall-cmd --zone=ssh-access --add-source=46.51.158.3 --permanent
firewall-cmd --zone=ssh-access --add-source=54.228.167.152 --permanent
firewall-cmd --zone=ssh-access --add-source=54.72.152.22 --permanent
firewall-cmd --zone=ssh-access --add-service=ssh --permanent
firewall-cmd --reload

2. Root Does not Permit Root Connection

Sometimes, SSH remote root login is disabled on your server, and you will get the "Root does not permit root connection" error while connecting your server to Snapshooter.

In this case, you will need to enable your server's SSH remote root login.

To enable the SSH remote root login, edit the SSH configuration file:

nano /etc/ssh/sshd_config

Find the following line:

PermitRootLogin no

And, replace it with the following line:

PermitRootLogin yes

Save and close the file, then restart the SSH service:

systemctl restart sshd

3 Using a nat gateway so need to add manually

If your server is located behind the NAT gateway, you will need to configure your router to forward a port (eg ssh: 22, TCP) to your Linux server's internal IP.
