The available ICA channel types and their functionalities are described below. For details on configuring channel policies, see Channel policy.
CTXTW |
Yes |
Drawing (Thinwire): Enables access to the server's desktop (screen). This channel is for remoting graphics and user input (keyboard, mouse). This channel must be enabled for ICA to work.
Channel-specific actions:
For example: "actions": {
"audit": true,
"four_eyes": true,
"content_policy": {
"key": "433849548566ab327522e6"
"meta": {
"href": "/api/configuration/policies/content_policies/44287216854f482e7f2b24"
}
},
} |
CTXCAM |
None |
Audio Mapping: Enable access to the sound device of the server. |
CTXCDM |
None |
Drive Mapping: Enable access to the client's hard drives on the server. |
CTXCLIP |
None |
Clipboard: Enable access to the server's clipboard: the clipboard of the remote desktop can be pasted into local applications (and vice-versa). Note that SPS can audit the clipboard channel, but the Safeguard Desktop Player cannot search or display its contents. |
CTXSCRD |
None |
Smartcard: Enable using client side installed smartcards in server-side applications. |
CTXCOM1 |
None |
Printer (COM1): Enable access to the serial port COM1. |
CTXCOM2 |
None |
Printer (COM2): Enable access to the serial port COM2. |
CTXLPT1 |
None |
Printer (LPT1): Enable access to the parallel port LPT1. |
CTXLPT2 |
None |
Printer (LPT2): Enable access to the parallel port LPT2. |
CTXCPM |
None |
Printer Spooler: Enable access to the client's printer from the remote desktops and applications. |
CTXFLSH |
None |
HDX Mediastream: Some user widgets (for example Flash player) will not run on the server but on the client. These widgets are controlled from the server side using this channel. This is not supported by Safeguard Desktop Player and it is disabled by default. |
CTXUSB |
None |
USB: Enable using client side installed USB devices in server-side applications. |
CTXTWI |
None |
Seamless:Enable seamless channels that run a single application on the ICA server, instead of accessing the entire desktop. When disabled, the application window will be accessed along with an empty desktop. |
SPDBRS |
None |
Speedbrowse: Speeds up web browsing. Not currently supported by Safeguard Desktop Player, should be disabled by default. |
custom |
Yes |
Custom: Applications can open custom channels to the clients connecting remotely to the server. Enabling the Custom channel allows the clients to access all of these custom channels. To permit only specific channels, configure the channels field.
Channel-specific access control rules:
-
channels: To permit only specific custom channels, configure this field. For example:. "channels": {
"selection": "restricted",
"restrictions": [ "CUSTOM1", "CUSTOM2" ]

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). |
