Fix PermitRootLogin error during SMC Linux migration-Server Migration Center(SMC)-阿里云帮助中心

Fix the PermitRootLogin error during SMC Linux migration by enabling root SSH login on the source server.

This error occurs when you use SMC to migrate a Linux OS to Anolis OS and root SSH login is disabled on the source server.

Problem description

SMC reports this error during a Linux OS migration to Anolis OS.

The PermitRootLogin parameter in /etc/ssh/sshd_config on the source server is not set to yes.

Set PermitRootLogin to yes in /etc/ssh/sshd_config:

sudo sed -i 's/^PermitRootLogin no$/PermitRootLogin yes/' /etc/ssh/sshd_config

Verify that PermitRootLogin is set to yes:

grep ^PermitRootLogin /etc/ssh/sshd_config

Restart the SSH service to apply the change:
```
sudo systemctl restart sshd
```
After you resolve the network issue, run the SMC client to retry the operation. For more information, see Run the SMC client.
