Introduction to server remote connection methods - Simple Application Server

Simple Application Server supports multiple remote connection methods, including Workbench, third-party client tools, and VNC rescue connection. The method you choose depends on the operating systems of your instance and on-premises device, and your specific needs.

Connection method	Core advantages	Instance operating system	Supported logon credentials	Requires local software installation
Workbench (browser)	Browser-based access, no configuration required	Linux / Windows	One-click logon, password	No
SSH client tool	Supports key pair logon, stable connection	Linux	Password, key pair	Yes
RDP client tool	Graphical interface, intuitive operation	Windows	Password	Yes
VNC rescue connection	Emergency troubleshooting, such as for SSH server or firewall issues.	Linux / Windows	Password	No

Choose a suitable remote connection tool

Workbench

You can securely log on to and manage your server from a browser without installing any local software.

To connect to a Linux server, see Connect to a Linux server using Workbench.
To connect to a Windows server, see Connect to a Windows server using Workbench.

Local SSH and RDP clients

You can install a client on your local computer to establish a more stable connection. This method also supports key pair logon for Linux servers.

Linux servers: You can use an SSH client, such as PuTTY, for command-line operations. For more information, see Connect to a Linux server using an SSH client.
Windows servers: You can use a Remote Desktop (RDP/MSTSC) client for graphical management. For more information, see Connect to a Windows server using MSTSC.

VNC rescue connection

If you cannot connect to a server using conventional methods because of configuration errors, such as firewall errors or an abnormal SSH service, you can use a VNC rescue connection. For more information, see Use a rescue connection to connect to a server.

FAQ

Q1: What is the default username for the server?

Linux systems: The default administrator username is root.
Windows systems: The default administrator username is Administrator.

Q2: What is the initial password for the server?

The server does not have an initial password. Before you can log on with a password for the first time, you must set or reset the server password in the console.

Q3: Why can't I use a password to log on to a Linux server after attaching a key pair?

After you attach a key pair to a Linux server and restart it, password-based logon is disabled by default. To restore password-based logon, simply reset the password in the console (you can use the original password).
