Logging In to a Linux ECS from a Mobile Terminal

Scenarios

If you want to manage Linux ECSs anytime, anywhere, you can log in to them from an iOS or Android terminal.

This section describes how to remotely log in to a Linux ECS from a mobile terminal using the username and password.

For instructions about how to log in to a Linux ECS from an iOS terminal through Termius, see Logging In to a Linux ECS from an iOS Terminal.
For instructions about how to log in to a Linux ECS from an Android terminal through JuiceSSH, see Logging In to a Linux ECS from an Android Terminal.

Prerequisites

The target ECS is running.
You have obtained the username and password for logging in to the ECS. If the password is forgotten, reset the password by referring to Resetting the Password for Logging In to an ECS on the ECS Console.
You have bound an EIP to the ECS. For details, see Binding an EIP.

Access to port 22 is allowed in the inbound direction of the security group that the ECS belongs to. For details, see Configuring Security Group Rules.

Logging In to a Linux ECS from an iOS Terminal

Before performing the operation, make sure that you have installed an SSH client tool, for example, Termius, on the iOS terminal. In this example, the Linux ECS runs CentOS 7.6, and it is authenticated using a username and password.

Start Termius and tap New Host.
