### Create from GlobalSSH Entry

1. Go to **Network Acceleration** product category, find the SSH acceleration channel GlobalSSH entry, and click on the **Create** button  

2. Enter the server IP that needs acceleration, select a region option that can cover your server's physical location, input the server port number, and create.  
For example: If the server is in the United States (Washington), select the United States (Washington) option; if the server is in Thailand (Bangkok), you can select either Hong Kong or Singapore option that can cover the Thailand (Bangkok) area

The Entry-level version of GlobalSSH uses a shared IP approach, different instances will be assigned different ports for SSH connection, so the GlobalSSH port will not be the same as the server port.

## How to Use

Once created successfully, a domain with an ipssh.net suffix will be generated.  
Note: ipssh.net is the official domain for the GlobalSSH product, however, some acceleration domains ending with ucloudgda.com are still available for use.

> Accelerated domains are prohibited from being directly used for HTTP/HTTPS access.

**Linux System**  

In your remote login tool, use the **accelerated domain** for login.

Command line login example (CentOS):  
```
ssh {username}@{AcceleratingDomain}
```
Free version:
```
ssh {username}@{AcceleratingDomain} -p ${GlobalSSHPort}
```

Friendly reminder: When using other vendors' cloud hosts or different Linux distributions, note that the SSH login username may vary.

!> Risk Warning: SCloud provides basic attack defense of no more than 3 Gbps for each accelerated IP for free (the maximum free protection traffic supported varies between regions). When the accelerated instance suffers a DDoS attack surpassing the basic defense threshold, SCloud will block the IP of the accelerated region's entry point, and the accelerated instance will revert to source handling. If your accelerated instance continues to suffer DDoS attacks, the product provider reserves the right to reclaim the instance.
