SSH authentication policies

Lists the configured authentication methods that can be used in a connection. Each connection policy uses an authentication policy to determine how the client can authenticate to the target server. Separate authentication methods can be used on the client and the server-side of the connection.

URL
GET https://<IP-address-of-SPS>/api/configuration/ssh/authentication_policies
Cookies
Cookie name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API.

Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Sample request

The following command lists SSH authentication policies.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/ssh/authentication_policies

The following command retrieves the properties of a specific policy.

    You have to use the signing_CA element to reference a signing certificate authority.

  • publish_to_ldap

    SPS generates an X.509 certificate and the corresponding private key for every connection policy, and uses this certificate in the server-side connections. The certificate is also uploaded to the LDAP database set in the LDAP Server of the connection policy. That way the server can authenticate the client to the generated certificate stored under the user's username in the LDAP database. You can configure LDAP servers using the /api/configuration/policies/ldap_servers endpoint, and connection policies using the /api/configuration/ssh/connections endpoint.

    You have to use the signing_CA element to reference a signing certificate authority.

X509_identity string

References the private key and certificate used for authenticating on the remote server. You can configure X.509 certificates and keys at the /api/configuration/x509/ endpoint.

To modify or add an X.509 certificate and private key, use the value of the returned key as the value of the X509_identity element, and remove any child elements (including the key).

signing_CA string

References the Certificate Authority (CA) used for signing certificates. You can configure signing CAs at the /api/configuration/policies/signing_cas/ endpoint.

Authentication based on username and password.

Set to true to enable password-based authentication on the remote server.

public_key Top level item

Authentication based on public-private encryption keypairs.

Use the selection child element to disable or configure authentication using public-private keypairs on the remote server.

selection string

Configures authenticaton on the remote server using public-private keypairs. The following values are possible:

  • disabled

    Disables the authentication method.

  • publish_to_ldap

    SPS generates a keypair, and uses this keypair in the server-side connection. The public key of this keypair is also uploaded to the LDAP database set in the LDAP Server of the connection policy. That way the server can authenticate the client to the generated public key stored under the user's username in the LDAP database. You can configure LDAP servers using the /api/configuration/policies/ldap_servers endpoint, and connection policies using the /api/configuration/ssh/connections endpoint.

  • fix

    Uses a private key in the server-side connection.

    You have to use the private_key element to reference the private key.

  • agent

    Allow the client to use agent-forwarding, and use its own keypair on the server-side.

    If this option is used, SPS requests the client to use its SSH agent to authenticate on the target server. Therefore, you must configure your clients to enable agent forwarding, otherwise authentication will fail. For details on enabling agent forwarding in your SSH application, see the documentation of the application.

private_key string

References the key of the private key used for authenticating with a public-private keypair on the remote server. You can configure private keys at the /api/configuration/private_keys/ endpoint.

Element Type Description
key string Top level element, contains the ID of the policy.
body Top level element (string) The elements of the SSH settings policy.
client_side_algorithms Top level element (list) Lists the permitted client-side encryption parameters.
cipher list Lists the permitted client-side cipher algorithms.
compression list Lists the permitted client-side compression algorithms.
kex list Lists the permitted client-side KEX algorithms.
mac list Lists the permitted client-side MAC algorithms.
greeting string Greeting message for the connection.
name string Name of the SSH settings policy.
preconnect_channel_check boolean

Before establishing the server-side connection, SPS can evaluate the connection and channel policies to determine if the connection might be permitted at all. The server-side connection is established only if the evaluated policies permit the client to access the server.

To enable this function, set the parameter to true.

server_side_algorithms Top level element (list) Lists the permitted server-side encryption parameters.
cipher list Lists the permitted server-side cipher algorithms.
compression list Lists the permitted server-side compression algorithms.
kex list Lists the permitted server-side KEX algorithms.
mac list Lists the permitted server-side MAC algorithms.
software_version string Specifies additional text to append to the SSH protocol banner sent by the server upon connection.
strict_mode boolean

When this option is enabled, SPS rejects connections that use unrealistic parameters (for example, terminals of thousand by thousand characters) and port-forwarding connections where the address in the port-forwarding request and the channel-opening request does not match. Note that this can interfere with certain client or server applications.

Strict mode is allowed by default. To turn it off, set the parameter to false.

timeout int Connection timeout, in seconds. Note that the SPS web UI displays the same value in milliseconds.
userauth_banner string You can display a banner message to the clients before authentication (as specified in RFC 4252 — The Secure Shell (SSH) Authentication Protocol). You can use this banner to inform the users that the connection is audited.

SSH host keys and certificates

SPS stores the host keys and X.509 certificates of the trusted servers. When a client tries to connect to a server, SPS verifies the host key or the certificate of the server, and allows connections only to the servers that have their keys available on SPS (unless the SSH Connection Policy is configured differently).

URL
GET https://<IP-address-of-SPS>/api/ssh-host-keys
Cookies
Cookie name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API.

Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Sample request

The following command lists the SSH host keys and certificates of the servers that the users can connect to using SSH.

curl --cookie cookies https://<IP-address-of-SPS>/api/ssh-host-keys/

The following command retrieves the properties of a specific key.

curl --cookie cookies https://<IP-address-of-SPS>/api/ssh-host-keys/<object-id>

Search and filter host keys

To list only specific host keys, you can use the following filters.

  • List every host key and certificate:

    GET https://<IP-address-of-SPS>/api/ssh-host-keys
  • List host keys of a specific type:

    GET https://<IP-address-of-SPS>/api/ssh-host-keys?type=<type-to-list>

    Possible values: ssh-rsa, ssh-dss, x509v3-sign-rsa, x509v3-sign-dss. For example:

    GET https://<IP-address-of-SPS>/api/ssh-host-keys?type=ssh-rsa
  • List host keys for a specific port number:

    GET https://<IP-address-of-SPS>/api/ssh-host-keys?port=<port-number-to-list>
  • List host keys for a specific host address (IPv4 or IPv6):

    GET https://<IP-address-of-SPS>/api/ssh-host-keys?address=<host-address>
  • For a complex filter, separate the parameters with an ampersand (&) character, for example:

    GET https://<IP-address-of-SPS>/api/ssh-host-keys?port=<port-number-to-list>&type=<type-to-list>

The response to such requests is a JSON object, where the items list includes the IDs of the selected host keys (or an empty list). For example, filtering for ssh-dss keys could return a similar list:

{
  "meta": {
    "href": "/api/ssh-host-keys",
    "parent": "/api"
  },
  "items": [
    {
      "key": "ssh-dss-10.110.0.1:22",
      "meta": {"href": "/api/ssh-host-keys/ssh-dss-10.110.0.1:22"}
    },
    {
      "key": "ssh-dss-10.110.0.2:2222",
      "meta": {"href": "/api/ssh-host-keys/ssh-dss-10.110.0.2:2222"}
    }
  ]
}
Add new host key

To upload a new host key or certificate, you have to POST the host key and other data as a JSON object to the https://<IP-address-of-SPS>/api/ssh-host-keys endpoint. For details, see Create a new object. The body of the POST request must contain a JSON object with the parameters listed in Element . If the POST request is successful, the response includes an ID for the host key in the following format: <type-of-the-key>-<host-address>:<host-port>. For example:

{
  "address": "10.110.0.1",
  "port": 22,
  "type": {
    "selection": "ssh-rsa",
    "value": "AAAAB3NzaC1yc2EAAAAD...zvMwgc=="
  }
}

Note that for IPv6 addresses, SPS will automatically convert the address to its canonical format.

Delete host key

To delete a host key or certificate, you have to DELETE https://<IP-address-of-SPS>/api/ssh-host-keys/<ID-of-the-host-key> endpoint. For details, see Delete an object. If the DELETE request is successful, the response includes only the meta object, for example:

{
    "meta": {
        "href": "/api/ssh-host-keys/ssh-rsa-10.10.20.35:22",
        "parent": "/api/ssh-host-keys"
    }
}

You must commit your changes to actually delete the object from SPS.
