Logging In to a Linux ECS Using an SSH Password

Scenarios

Prerequisites

• The target ECS is running.
• 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 which the ECS belongs to. For details, see Configuring Security Group Rules.
• The network connection between the login tool (PuTTY) and the target ECS is normal. For example, the default port 22 is not blocked by the firewall.

Logging In to a Linux ECS from a Local Linux Server

1. On the Linux CLI, run the following command to log in to the ECS:

   ssh xx.xx.xx.xx

   Note

   xx.xx.xx.xx indicates the EIP bound to the ECS.

2. Verify the SSH fingerprint of the ECS and enter yes.

   The authenticity of host 'xx.xx.xx.xx (xx.xx.xx.xx)' can't be established.
   ECDSA key fingerprint is SHA256:rnKuzrUSYS03MCoaxxxxxxxxxxxxxxxxxxxxxxxxxxx.
   ECDSA key fingerprint is MD5:cf:64:5b:5e:74:30:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx.
   Are you sure you want to continue connecting (yes/no)? yes                
   Warning: Permanently added 'xx.xx.xx.xx' (ECDSA) to the list of known hosts.
