psrp – Run tasks over Microsoft PowerShell Remoting Protocol

New in version 2.7.


Synopsis

  • Run commands or put/fetch on a target via PSRP (WinRM plugin)
  • This is similar to the winrm connection plugin which uses the same underlying transport but instead runs in a PowerShell interpreter.

Requirements

The below requirements are needed on the local master node that executes this connection.

  • pypsrp (Python library)

Parameters

Parameter Choices/Defaults Configuration Comments

auth

string

  • basic
  • certificate

  • negotiate ←

  • kerberos
  • ntlm
  • credssp

var: ansible_psrp_auth

The authentication protocol to use when authenticating the remote user.

The default, negotiate, will attempt to use Kerberos if it is available and fall back to NTLM if it isn't.

ca_cert

path

var: ansible_psrp_cert_trust_path

var: ansible_psrp_ca_cert

The path to a PEM certificate chain to use when validating the server's certificate.

This value is ignored if cert_validation is set to ignore.


aliases: cert_trust_path

cert_validation

string

  • validate ←

  • ignore

var: ansible_psrp_cert_validation

Whether to validate the remote server's certificate or not.

Set to ignore to not validate any certificates.

ca_cert can be set to the path of a PEM certificate chain to use in the validation.

certificate_key_pem

path

var: ansible_psrp_certificate_key_pem

The local path to an X509 certificate key to use with certificate auth.

certificate_pem

path

var: ansible_psrp_certificate_pem

The local path to an X509 certificate to use with certificate auth.

configuration_name

string

Default:

"Microsoft.PowerShell"

var: ansible_psrp_configuration_name

The name of the PowerShell configuration endpoint to connect to.

connection_timeout

integer

Default:

30

var: ansible_psrp_connection_timeout

The connection timeout for making the request to the remote host.

This is measured in seconds.

credssp_auth_mechanism

string

  • auto ←

  • kerberos
  • ntlm

var: ansible_psrp_credssp_auth_mechanism

The sub authentication mechanism to use with CredSSP auth.

When auto, both Kerberos and NTLM is attempted with kerberos being preferred.

credssp_disable_tlsv1_2

boolean

  • no ←

  • yes

var: ansible_psrp_credssp_disable_tlsv1_2

Disables the use of TLSv1.2 on the CredSSP authentication channel.

This should not be set to yes unless dealing with a host that does not have TLSv1.2.

credssp_minimum_version

integer

Default:

2

var: ansible_psrp_credssp_minimum_version

The minimum CredSSP server authentication version that will be accepted.

Set to 5 to ensure the server has been patched and is not vulnerable to CVE 2018-0886.

ignore_proxy

boolean

  • no ←

  • yes

var: ansible_psrp_ignore_proxy

Will disable any environment proxy settings and connect directly to the remote host.

This option is ignored if proxy is set.

max_envelope_size

integer

Default:

153600

var: ansible_psrp_max_envelope_size

Sets the maximum size of each WSMan message sent to the remote host.

This is measured in bytes.

Defaults to 150KiB for compatibility with older hosts.

message_encryption

string

  • auto ←

  • always
  • never

var: ansible_psrp_message_encryption

Controls the message encryption settings, this is different from TLS encryption when ansible_psrp_protocol is https.

Only the auth protocols negotiate, kerberos, ntlm, and credssp can do message encryption. The other authentication protocols only support encryption when protocol is set to https.

auto means means message encryption is only used when not using TLS/HTTPS.

always is the same as auto but message encryption is always used even when running over TLS/HTTPS.

never disables any encryption checks that are in place when running over HTTP and disables any authentication encryption processes.

negotiate_delegate

boolean

  • no
  • yes

var: ansible_psrp_negotiate_delegate

Allow the remote user the ability to delegate it's credentials to another server, i.e. credential delegation.

Only valid when Kerberos was the negotiated auth or was explicitly set as the authentication.

Ignored when NTLM was the negotiated auth.

negotiate_hostname_override

string

var: ansible_psrp_negotiate_hostname_override

Override the remote hostname when searching for the host in the Kerberos lookup.

This allows Ansible to connect over IP but authenticate with the remote server using it's DNS name.

Only valid when Kerberos was the negotiated auth or was explicitly set as the authentication.

Ignored when NTLM was the negotiated auth.

negotiate_send_cbt

boolean

  • no

  • yes ←

var: ansible_psrp_negotiate_send_cbt

Send the Channel Binding Token (CBT) structure when authenticating.

CBT is used to provide extra protection against Man in the Middle MitM attacks by binding the outer transport channel to the auth channel.

CBT is not used when using just HTTP, only HTTPS.

negotiate_service

string

Default:

"WSMAN"

var: ansible_psrp_negotiate_service

Override the service part of the SPN used during Kerberos authentication.

Only valid when Kerberos was the negotiated auth or was explicitly set as the authentication.

Ignored when NTLM was the negotiated auth.

operation_timeout

integer

Default:

20

var: ansible_psrp_operation_timeout

Sets the WSMan timeout for each operation.

This is measured in seconds.

This should not exceed the value for connection_timeout.

path

string

Default:

"wsman"

var: ansible_psrp_path

The URI path to connect to.

port

integer

var: ansible_port

var: ansible_psrp_port

The port for PSRP to connect on the remote target.

Default is 5986 if protocol is not defined or is https, otherwise the port is 5985.

protocol

string

  • http
  • https

var: ansible_psrp_protocol

Set the protocol to use for the connection.

Default is https if port is not defined or port is not 5985.

proxy

string

var: ansible_psrp_proxy

Set the proxy URL to use when connecting to the remote host.

read_timeout

integer

added in 2.8

Default:

30

var: ansible_psrp_read_timeout

The read timeout for receiving data from the remote host.

This value must always be greater than operation_timeout.

This option requires pypsrp >= 0.3.

This is measured in seconds.

reconnection_backoff

integer

added in 2.8

Default:

2

var: ansible_psrp_connection_backoff

var: ansible_psrp_reconnection_backoff

The backoff time to use in between reconnection attempts. (First sleeps X, then sleeps 2*X, then sleeps 4*X, ...)

This is measured in seconds.

The ansible_psrp_reconnection_backoff variable was added in Ansible 2.9.

reconnection_retries

integer

added in 2.8

Default:

0

var: ansible_psrp_reconnection_retries

The number of retries on connection errors.

remote_addr

string

Default:

"inventory_hostname"

var: ansible_host

var: ansible_psrp_host

The hostname or IP address of the remote host.

remote_password

string

var: ansible_password

var: ansible_winrm_pass

var: ansible_winrm_password

Authentication password for the remote_user. Can be supplied as CLI option.


aliases: password

remote_user

string

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
