The channel policy lists the channels (for example, terminal session and SCP in SSH, Drawing, Clipboard in RDP) that can be used in a connection. The channel policy can further restrict access to each channel based on the IP address of the client or the server, a user list, user group, or a time policy. For example, all clients may access the servers defined in a connection via SSH terminal, but the channel policy may restrict SCP access only to a single client. The policies set in the channel policy are checked when the user attempts to open a particular channel type in the connection.
Channel policies are protocol specific. To list the available Channel policies for a protocol, use the following command.
curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/<http|ica|rdp|ssh|telnet|vnc>/channel_policies
The following sections detail the properties of Channel policy objects.
GET https:<IP-address-of-SPS>/api/configuration/<http|ica|rdp|ssh|telnet|vnc>/channel_policies/<object-id>
| 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). |
The following command lists the properties of a specific RDP Channel policy object.

The following table lists the typical status and error codes for this request. For a complete list of error codes, see Application level error codes.
| Code | Description | Notes |
|---|---|---|
| 401 | Unauthenticated | The requested resource cannot be retrieved because the client is not authenticated and the resource requires authorization to access it. The details section contains the path that was attempted to be accessed, but could not be retrieved. |
| 401 | AuthenticationFailure | Authenticating the user with the given credentials has failed. |
| 404 | NotFound | The requested object does not exist. |
Archiving transfers data from SPS to an external storage solution, cleanup removes (deletes) old files. Archived data can be accessed and searched, but cannot be restored (moved back) to the SPS appliance. Only those closed audit-trail files are archived where the retention time has already elapsed. To list the available Archive policies, use the following command.
curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/policies/archive_cleanup_policies/

| Element | Type | Description | |
|---|---|---|---|
| name | string | Top level element, the name of the object. This name is also displayed on the SPS web interface. It cannot contain whitespace. | |
| include_node_id_in_path | boolean | Include the Cluster Node ID in the path. Recommended to set to True if the SPS instance is a node in a cluster. This ensures that the ID of the node is included in the path of the relevant directory, which is required to prevent cluster nodes from archiving data to the same location, and so overwriting each other's data and resulting in data loss. | |
| notification_event | Top level element | ||
| type | string (all | errors-only | none) |
| |
| send_filelist | boolean |
This is meaningful only if notification_event is set to all. True if the list of files are included in the notification e-mail. | |
| file_count_limit | integer |
This is meaningful only if notification_event is set to all and send_filelist is set to True. The maximum number of files that are included in the notification e-mail. | |
| target | Top level element | Defines the address of the archive server, which protocol to use to access it, and other parameters. SPS can be configured to use the SMB/CIFS, and NFS protocols to access the archive server. | |
| type | string (smb | nfs | none) |
| |
| server | Top level element | ||
| domain | string |
Only if type is set to smb. The domain name of the target server | |
| protocol_version | string |
Only if type is set to smb. The SMB protocol to use when SPS connects to the server. Servers are usually backwards compatible with earlier protocol versions (for example, a server that supports version 2.1 supports versions 2.0 and 1.0 as well). | |
| share | string |
Only if type is set to smb. The name and directory path of the share in the following format: share_name/path/to/directory | |
| authentication | Top level element |
Only if type is set to smb. | |
| path | string | The path to the archive directory on the target server | |
| start_times | list of strings | The time when the archive process starts in H:MM or HH:MM format. | |
| template | string |
SPS organizes the audit trails into directories based on the date or the protocol. The subdirectories are created directly into the archive directory. The following subdirectory structures are possible:
| |
| retention_days | integer (days) | Data older than this value is archived to the external server. The archived data is deleted from SPS. | |
| Elements of server | Type | Description | |
|---|---|---|---|
| server | Top level element | ||
