Connecting to your Hong Kong VPS via SSH is the first step to unlocking full root control, ultra-low latency management (10ms to mainland China), and deployment of applications like WordPress, Node.js, or game servers. With CN2 GIA + BGP routing and native IP addresses, a secure SSH session ensures fast, encrypted access from anywhere. This step-by-step guide covers Windows, macOS, Linux, and mobile clients—using the instant-deployment Hong Kong VPS platform that requires no ICP filing and activates in under 60 seconds.
Step 1: Get Your Hong Kong VPS Credentials
After ordering any Hong Kong VPS plan (from HK-1H2G at $4/month to HK-14H40G at $100/month), you receive:
- IP Address: Native Hong Kong IPv4 (e.g., 156.224.19.xxx)
- Root Password: Auto-generated or user-set
- SSH Port: Default 22 (customizable)
Test connectivity first:
ping 156.224.19.1 traceroute 156.224.19.1
Expect CN2 GIA hops and <1ms jitter from APAC locations.
Why SSH Over Panel Access?
While the self-service panel offers one-click reboots and traffic monitoring, SSH gives:
- Full CLI control (htop, rsync, docker)
- Scripted automation (Ansible, Fabric)
- Secure file transfer (SCP/SFTP)
- Real-time log tailing (
journalctl -f)
Step 2: Generate SSH Key Pair (Recommended)
Password login is convenient but risky. Use 4096-bit RSA or Ed25519 keys.
On Linux/macOS
ssh-keygen -t ed25519 -C "hk-vps-2025" # Press Enter for default path (~/.ssh/id_ed25519) cat ~/.ssh/id_ed25519.pub
Copy the public key output.
On Windows (PowerShell)
ssh-keygen -t ed25519 -C "hk-vps-2025" type $env:USERPROFILE\.ssh\id_ed25519.pub
Save private key securely—never share it.
Step 3: Add Public Key to Hong Kong VPS
Login with password first (replace your-ip):
ssh root@your-ip # Enter root password
Create .ssh directory and paste key:
mkdir -p ~/.ssh && chmod 700 ~/.ssh nano ~/.ssh/authorized_keys # Paste public key, save (Ctrl+O, Enter, Ctrl+X) chmod 600 ~/.ssh/authorized_keys
Disable Password Login (Security Hardening)
sudo nano /etc/ssh/sshd_config
Change:
PasswordAuthentication no PubkeyAuthentication yes PermitRootLogin prohibit-password
Restart SSH:
sudo systemctl restart sshd
Exit and reconnect—key-only now enforced.
Step 4: Connect via SSH Clients
Terminal (Linux/macOS)
ssh -i ~/.ssh/id_ed25519 root@your-ip
# Or add to ~/.ssh/config for alias:
Host hkvps
HostName your-ip
User root
IdentityFile ~/.ssh/id_ed25519
Port 22
# Then: ssh hkvps
Windows: PuTTY
- Download PuTTY
- Open PuTTY → Session → Enter IP
- Connection → SSH → Auth → Browse private key (.ppk)
- Convert OpenSSH key to .ppk using PuTTYgen if needed
- Save session as “HongKongVPS” → Open
Windows: Built-in OpenSSH (Windows 10+)
ssh -i %USERPROFILE%\.ssh\id_ed25519 root@your-ip
Mobile: Termius (iOS/Android)
- Import private key via iCloud/Google Drive
- New Host → IP, username root, key auth
- Connect with <5ms touch-to-shell from China
Step 5: Optimize SSH Connection for Speed
Leverage Hong Kong VPS CN2 GIA low latency:
Use Modern Ciphers
Edit ~/.ssh/config:
Host *
Ciphers aes128-ctr,aes192-ctr,aes256-ctr
KexAlgorithms curve25519-sha256,curve25519-sha256@libssh.org
MACs hmac-sha2-256,hmac-sha2-512
Enable Compression (High-Latency Links)
ssh -C root@your-ip
Persistent Connection (Multiplexing)
Host hkvps
ControlMaster auto
ControlPath ~/.ssh/cm_socket/%r@%h:%p
ControlPersist 4h
Subsequent commands reuse tunnel—no re-auth delay.
Step 6: Secure File Transfer (SCP & SFTP)
SCP (Single File)
scp -i ~/.ssh/id_ed25519 local-file.txt root@your-ip:/root/ scp -r root@your-ip:/var/www/ ./backup/
SFTP (Interactive)
sftp -i ~/.ssh/id_ed25519 root@your-ip > put wp-config.php > get access.log
RSync Over SSH (Efficient Sync)
rsync -avz --progress -e "ssh -i ~/.ssh/id_ed25519" ./site/ root@your-ip:/var/www/html/
Step 7: Automate Tasks with SSH
Passwordless Cron Backup
0 3 * * * rsync -avz -e "ssh -i /home/backup/.ssh/id_ed25519" /var/www/ user@backup-server:/hk-vps/
Ansible Playbook Example
# inventory.ini
[hkvps]
your-ip ansible_user=root ansible_ssh_private_key_file=~/.ssh/id_ed25519
# deploy.yml
- hosts: hkvps
tasks:
- name: Update system
apt:
upgrade: yes
update_cache: yes
Run: ansible-playbook -i inventory.ini deploy.yml
Step 8: Troubleshooting Common SSH Issues
| Issue | Solution |
|---|---|
| Connection refused | Check firewall: ufw allow OpenSSH |
| Permission denied (publickey) | Verify ~/.ssh/authorized_keys permissions (600) |
| Timeout | Ping test IP first; avoid VPN during setup |
| Key rejected | Use ssh -v for debug; check server logs: journalctl -u sshd |
One free IP replacement within 24h if blocked by non-user fault.
Step 9: Advanced: SSH Tunneling & Port Forwarding
Local Port Forward (Access Baota Panel Securely)
ssh -L 8888:localhost:8888 root@your-ip # Open browser: http://localhost:8888
Remote Port Forward (Expose Local Service)
ssh -R 8080:localhost:80 root@your-ip
Dynamic SOCKS Proxy (Browse via VPS)
ssh -D 1080 root@your-ip # Set browser proxy to SOCKS5 127.0.0.1:1080
Step 10: Best Practices for Ongoing SSH Security
- Change default port:
Port 2222insshd_config - Install Fail2Ban:
apt install fail2ban - Use 2FA with Google Authenticator PAM
- Monitor logs:
tail -f /var/log/auth.log - Enable 99.99% uptime SLA alerts via panel
Conclusion: Connect Fast, Manage Smarter
