# How to Grant Server Access to GB Network Solutions Support Team?

By following these instructions, you will enable the GB Network Solutions support team to securely access your server and provide the necessary assistance.

**Applicable To**
Servers running Linux Operating Systems

**Overview**
This guide outlines the steps to provide the GB Network Solutions Support team access to your server for troubleshooting and assistance. Follow these instructions carefully or consult your system administrator if you need assistance.

**Authorized IP Address**
Our support team will only connect to your server from the following IP address:

* 103.72.162.120

Please ensure this IP address is whitelisted in your security software (e.g., antivirus, firewall, Imunify360, CPHulk, Fail2Ban, CSF/iptables).

**SSH Key Authentication**
To allow access, place our SSH public key into your server’s **/root/.ssh/authorized_keys** file. Here’s the key you need to add:

```
-----BEGIN GB NETWORK SOLUTIONS PUBLIC KEY-----PLEASE DO NOT COPY THIS LINE-------

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDXaitF0CgU2sXGAInM6RI7fY81EvQhO4qYjEtnsrtmcjCWcpTfIZpXbGQh8xMLLYOIvlUvRkepxTJA5DxxEuO+5o0oCEns+pKNN1Zn0B4EYytyZDGUjTEswAevGVo/MXDWA2rjqI7kbfU5Iv1gDtrcJNHT9l7jbOsRCG1qyZv/Hf80RKwvpxeyIWd2ABpYRcGFvcFEG61TIBYx0DYBbpbpths+nmJNZ8d1DzGX+3cXj2rUVUNeMKrJybcnfovCLJJjxL+l++nejVD/FUqs44ywbfsuOt838RDBg4pYnz90mY/B99+TL5P4d0LTuJJVTbMfV0kVFMuduz9zqKvlyxSH gbsupport@gbnetwork.my

-----END GB NETWORK SOLUTIONS PUBLIC KEY-----PLEASE DO NOT COPY THIS LINE-------
```

**Steps to Add the SSH Public Key**

1. Log into your server as root:

```
ssh root@your_server_ip
```

2. Ensure the .ssh directory exists:

```
mkdir -p /root/.ssh
chmod 700 /root/.ssh
```

3. Add the public key to the **authorized_keys** file:

```
echo "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDXaitF0CgU2sXGAInM6RI7fY81EvQhO4qYjEtnsrtmcjCWcpTfIZpXbGQh8xMLLYOIvlUvRkepxTJA5DxxEuO+5o0oCEns+pKNN1Zn0B4EYytyZDGUjTEswAevGVo/MXDWA2rjqI7kbfU5Iv1gDtrcJNHT9l7jbOsRCG1qyZv/Hf80RKwvpxeyIWd2ABpYRcGFvcFEG61TIBYx0DYBbpbpths+nmJNZ8d1DzGX+3cXj2rUVUNeMKrJybcnfovCLJJjxL+l++nejVD/FUqs44ywbfsuOt838RDBg4pYnz90mY/B99+TL5P4d0LTuJJVTbMfV0kVFMuduz9zqKvlyxSH gbsupport@gbnetwork.my" >> /root/.ssh/authorized_keys
chmod 600 /root/.ssh/authorized_keys
```

4. Confirm the key has been added:

```
cat /root/.ssh/authorized_keys
```

5. Update your firewall to allow connections from the GB Network authorized IP Address.
