How to setup SSH remote access on Proxmox VE?

To set up SSH remote access on Proxmox VE, follow these steps:

Install OpenSSH Server: Ensure that the OpenSSH server is installed on your Proxmox VE host. You can install it using the following command:
```
apt-get update
apt-get install openssh-server
```
Configure SSH Access: Edit the SSH configuration file to ensure it is set up correctly. Open the /etc/ssh/sshd_config file with a text editor like nano or vim:
```
nano /etc/ssh/sshd_config
```
- Ensure the following settings are configured:
```
PermitRootLogin no
PasswordAuthentication yes
```
- Save and close the file.
Restart SSH Service: After making changes to the SSH configuration, restart the SSH service to apply the changes:
```
systemctl restart sshd
```
Create a User Account: It's recommended to create a non-root user for SSH access. Use the following command to add a new user:
```
adduser yourusername
```
- Set a password for the new user when prompted.
Enable Firewall Rules: Ensure that your firewall allows SSH traffic. If you are using ufw, enable SSH access with:
```
ufw allow ssh
ufw enable
```
Test SSH Connection: From another machine, test the SSH connection to your Proxmox VE host using the newly created user account:
```
ssh yourusername@yourproxmoxve_host_ip
```

Example:
Suppose your Proxmox VE host has an IP address of 192.168.1.100 and you created a user named admin. You would test the SSH connection by running:

ssh admin@192.168.1.100

Security Considerations:

Use strong passwords or better yet, configure SSH key-based authentication for enhanced security.
Limit SSH access to specific IP addresses if possible.
