SSH channels

The available SSH channel types and their functionalities are described below. For details on configuring channel policies, see Channel policy.

Channel

Special options

Description

auth-agent

None

Agent: Forwards the SSH authentication agent from the client to the server.

x11

Yes

X11 Forward: Forwards the graphical X-server session from the server to the client. List the address of the client in the networks field to permit X11-forwarding only to the specified clients. Specify IP addresses or networks (in IP address/Prefix format). For example:

"networks": [
  {
    "selection": "address",
    "value": "192.168.1.1"
  },
  {
    "selection": "address",
    "value": "192.168.1.2"
  }
                        

NOTE: Certain client applications send the Target address as a hostname, while others as an IP address. If you are using a mix of different client applications, you might have to duplicate the channel rules and create IP-address and hostname versions of the same rule.

Channel-specific access control rules:

  • networks (list): To X11-forwarding only to specific clients, list the IP addresses or networks of the clients in this field. Leave it empty to permit access to every client. For details, see Limiting addresses in port forwarding.

local-forwards Yes

Local Forward: Forwards traffic arriving to a local port of the client to a remote host. To enable forwarding only between selected hosts, use the local_forwards field. If the local_forwards field is empty, local forwarding is enabled without restriction, the client may forward any traffic to the remote host.

For example:

"local_forwards": [
  {
    "host_address": {
      "selection": "address",
      "value": "192.168.100.1"
    },
    "host_port": 5555,
    "originator_address": {
      "selection": "address",
      "value": "192.168.1.1"
    }
  }
                        

Channel-specific access control rules:

  • local_forwards (list): To permit local forwarding only to specific addresses, list the addresses in this field. Leave it empty to enable without restriction. In this case the client may forward any traffic to the remote host.

    Enter the source of the forwarded traffic into the originator_address field, the target of the traffic into the host_address field. Specify IP addresses or networks (in IP address/Prefix format). These parameters are the end-points of the forwarded traffic (that is, the local host that sends data to the remote host), and not the SSH server or the client. For example, to enable forwarding from the 192.168.20.20 host to the remote host 192.168.50.50, enter 192.168.20.20 into the originator_address, and 192.168.50.50 into the host_address field. For details, see Limiting addresses in port forwarding.

remote-forwards Yes

Remote Forward: Forwards traffic arriving a remote port of the server to the client. To enable forwarding only between selected hosts, enter their IP addresses into the remote_forwards field. If the remote_forwards field is empty, remote forwarding is enabled without restriction, the SSH server may forward any traffic to the client.

For example:

"remote_forwards": [
  {
    "connected_address": {
      "selection": "address",
      "value": "192.168.100.1"
    },
    "connected_port": 5555,
    "originator_address": {
      "selection": "address",
      "value": "192.168.1.1"
    }
  }
                        

Channel-specific access control rules:

  • remote_forwards (list): To permit only specific forwardins, list the permitted addresses in this field. Leave it empty to permit forwarding without restrictions.

    Enter the source of the forwarded traffic into the originator_address, the target of the traffic into the connected_address field. Specify IP addresses or networks (in IP address/Prefix format). These parameters are the end-points of the forwarded traffic (that is, the remote host that sends data to the client), and not the SSH server. For example, to enable forwarding from the 192.168.20.20 remote host to the client 192.168.50.50, enter 192.168.20.20 into the originator_address, and 192.168.50.50 into the connected_address field. For details, see Limiting addresses in port forwarding.

session-exec Yes

Session Exec: Execute a remote command (for example rsync) without opening a session shell. List the permitted command in the execs field. You can use regular expressions to specify the commands. This field can contain only letters (a-z, A-Z), numbers (0-9), and the following special characters ({}()*?\\|[]).

Caution:

Restricting the commands available in Session Exec channels does not guarantee that no other commands can be executed. Commands can be renamed, or executed from shell scripts to circumvent such restrictions.

Channel-specific access control rules:

  • execs (list): List the permitted command in the execs field. Regular expressions may be used to specify the commands.

For example:

"execs": [
  "top",
  "ls"
                    
session-exec-scp Yes

Session Exec SCP: Transfers files using the Secure Copy (SCP) protocol.

Channel-specific actions:

  • log_transfer_to_db (list): (true|false): Make the list of file operations available in the Search > File operations column of the SPS web interface

  • log_transfer_to_syslog (list): (true|false): Send the file operations into the system log

For example:

"actions": {
  "audit": false,
  "four_eyes": false,
  "ids": false,
  "log_transfer_to_db": true,
  "log_transfer_to_syslog": true
}
session-subsystem Yes

Session Subsystem: Use a subsystem. Enter the name of the permitted subsystem into the subsystems field.

Channel-specific access control rules:

  • subsystems (list): List the permitted subsystems in this field.

For example:

"execs": [
  "top",
  "ls"
                    
session-exec-sftp Yes

Session SFTP: Transfers files using the Secure File Transfer Protocol (SFTP).

Channel-specific actions:

  • log_transfer_to_db (list): (true|false): Make the list of file operations available in the Search > File operations column of the SPS web interface

  • log_transfer_to_syslog (list): (true|false): Send the file operations into the system log

For example:

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 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).

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.

To modify or add a private key, use the value of the returned key as the value of the private_key element, and remove any child elements (including the key).
