SSH settings policies define protocol-level settings (algorithms, greetings and banners, timeout). You can create multiple policies, and choose the appropriate one for each SSH connection.
URL
GET https://<IP-address-of-SPS>/api/configuration/ssh/settings_policies
Cookies
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 more information on authentication, see Authenticate to the SPS REST API.
NOTE: 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). |

|
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. |

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. |

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).

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.
