Possible Causes of a Failure in Verifying a Host

If connectivity verification fails for a host, check the following items:

  1. Username and password.
  2. Startup status.
  3. Ports: Check that ports on the host have been enabled.
  4. Firewall policy: Run the iptables -L -n command to check whether access over port 22 is restricted.
  5. The IP address must be accessible from the public network. If you are using a private IP address, an SSH agent is required.
  6. CentOS version: If the host is running CentOS, ensure that the CentOS version is 6.0 or later.
  7. Windows version: If the host is running Windows, ensure that the Windows version is supported by CodeArts Deploy and you have configured the host. For details, see Configuring a Host in the User Guide.
