GlobalSSH is a product that improves the efficiency of cross-border remote server management. It mainly solves the problems of lag, connection failure, and slow transmission speed caused by unstable cross-border networks during remote management. It can greatly reduce the occurrence of lag and connection failures, and improve the efficiency of operations and maintenance work. GlobalSSH also offers free services, which I recommend to those who need it.

Registering for a Ucloud Account

If you don't have a Ucloud account yet, you can register at ucloud.cn. Note: Ucloud is a Chinese company, so real-name authentication is required. If you cannot accept this, it is recommended to give up.

Introduction to GlobalSSH

GlobalSSH mainly serves as a relay to accelerate SSH or Windows RDP connections. For example, if you have purchased a European server and experience severe packet loss and lag when connecting from China, you can use GlobalSSH for relay to improve connection speed and stability. GlobalSSH provides a free package with the following limitations:

• Bandwidth limit: 2Mbps, daily traffic: 1GB
• After the traffic is used up, the speed will be limited to 250Kbps for the rest of the day
• Entrance region is randomly assigned
• If not used within 7 days, it will be reclaimed
• Free version only accelerates ports 22/3389

Using GlobalSSH

If you have already registered and logged in, directly access https://console.ucloud.cn/upathx/globalssh to open the GlobalSSH backend and prepare to create a GlobalSSH acceleration service.

Choose the free package and fill in the server IP. For the server location, select the region closest to your server. For example, if you have a server in Europe, select Frankfurt. The port only supports 22/3389. If it is a Linux server, choose port 22; if it is a Windows server, choose port 3389.

After creating, use the acceleration domain name and GlobalSSH port provided by GlobalSSH to connect, which is equivalent to connecting to your own server. GlobalSSH internally transfers traffic through its own dedicated line, thereby achieving acceleration.

Conclusion

I have been using GlobalSSH for a while, and this service is quite good. It also has a free version, and the acceleration effect is also good. Unfortunately, the free version can only accelerate fixed ports, and if there is no traffic within 7 days, it will be reclaimed, requiring the creation of a new acceleration service.
