- The BMS must be in Running state.
- You have obtained the private key file used during BMS creation.
- You have bound an EIP to the BMS. For details, see Binding an EIP to a BMS.
- You have configured the inbound rules of the security group. For details, see section Adding Security Group Rules.
- The network connection between the login tool (such as PuTTY) and the target BMS is normal. For example, the default port 22 is not blocked by the firewall.
Logging In to the Linux BMS from a Windows Computer
You can use the following methods to log in to a Linux BMS from a local PC running Windows:
Method 1: Use PuTTY to log in to the BMS.
Before logging in to the BMS using PuTTY, ensure that the private key file has been converted to .ppk format.
- Check whether the private key file has been converted to .ppk format.
- If yes, go to step 7.
- If no, go to step 2.
- Visit the following website and download PuTTY and PuTTYgen:
PuTTYgen is a private key generator, which is used to create a key pair that consists of a public key and a private key for PuTTY.
- Run PuTTYgen.
- In the Actions area, click Load and import the private key file that you stored when creating the BMS.
Ensure that the private key file is in the format of All files (*.*).
- Click Save private key.
- Save the converted private key to the local PC. for example, kp-123.ppk, to the local computer.
- Double-click PUTTY.EXE. The PuTTY Configuration page is displayed.

- Click OK to log in to the BMS.
Logging In to the Linux BMS from a Linux Computer
Perform the following operations to log in to a Linux BMS from a local PC running Linux: The following procedure uses private key file
as an example to describe how to log in to the BMS.
- On the Linux CLI, run the following command to change operation permissions:
chmod 400 /path/KeyPair-ee55
In the preceding command, path refers to the path under which the key file is stored.
- Run the following command to log in to the BMS:
ssh -i /path/KeyPair-ee55 xxx@EIP of the BMS
- In the preceding command, path refers to the path under which the key file is stored.
- xxx indicates the username of the BMS image. Contact the administrator to obtain the username.
