Failed to deploy Orion agent for Linux as unable to identify target machine's operating system

Updated July 25, 2018


When attempting to remote deploy the Orion agent for Linux, you may receive the following error when testing the credentials: 


"Failed to validate credentials for deployment. Unable to identify target machine's operating system."  OR

"Failed to validate credentials for deployment. Authentication to remote host failed."


You have tested the SSH credentials via putty directly from Orion server to the Linux host you are trying to deploy the Orion Linux agent and they work just fine.


Please check the likely causes and resolutions section for fix/workaround.


  • NPM 12.x +
  • SAM 6.x +
  • Orion Linux Agent


Your target system may not have a supported Linux distribution. The Orion agent for Linux supports the following distributions:

  • Red Hat Enterprise Linux 5 x64, x86
  • Red Hat Enterprise Linux 6 x64, x86
  • Red Hat Enterprise Linux 7 x64
  • CentOS-5 x64, x86
  • CentOS-6 x64, x86
  • CentOS-7 x64
  • SUSE Linux 10 x64, x86
  • Ubuntu-14 x64
  • Amazon Linux AMI x64



1. Check if your Linux distribution is supported. If it is not supported, you may need to upgrade the Linux distribution or install a supported Linux distribution.

2. Ensure the SFTP service on the Linux server is enabled and the corresponding SFTP ports are open on the server in local and network firewall to receive traffic from Orion server otherwise you may see below error(s) depending on Linux distribution and SFTP server in use.

Failed to receive FXP_VERSION

at SolarWinds.AgentManagement.InstallerUtils.SshDeployment.SftpClient.IntializeSftp()


3. If the distribution is supported but still getting authentication failed error, you should manually deploy the Orion agent for Linux. See your SAM/NPM administrator guide for instructions and check port and firewall requirements for Orion agent


For more detailed information of various deployment methods and configuration options possible refer to the Linux Agent Deployment Thwack post.
