| Synopsis |
| -------- |
| |
| **ndnpoke** [-h] [-f] [-F] [-x *freshness*] [-i *identity*\|\ -D] [-w *timeout*] [-V] *name* |
| |
| Description |
| ----------- |
| |
| :program:`ndnpoke` is a simple producer program that reads a payload from the standard |
| input and publishes it as a single Data packet. The Data packet is either sent as a |
| response to an incoming Interest matching *name*, or immediately pushed to the local |
| NDN forwarder as "unsolicited Data" if the **-f** flag is specified. |
| |
| Options |
| ------- |
| |
| ``-h, --help`` |
| Print help and exit. |
| |
| ``-f, --force`` |
| Send the Data packet without waiting for an incoming Interest. |
| |
| ``-F, --final`` |
| Set the ``FinalBlockId`` to the last component of *name*. |
| |
| ``-x, --freshness <freshness>`` |
| Set ``freshness`` (in milliseconds) as the ``FreshnessPeriod``. |
| |
| ``-i, --identity <identity>`` |
| Use ``identity`` to sign the Data packet. |
| |
| ``-D, --digest`` |
| Use ``DigestSha256`` signature type instead of the default ``SignatureSha256WithRsa``. |
| |
| ``-w, --timeout <timeout>`` |
| Quit the program after ``timeout`` milliseconds, even if no Interest has been received. |
| |
| ``-V, --version`` |
| Print version and exit. |
| |
| Exit Status |
| ----------- |
| |
| 0: Success |
| |
| 1: An unspecified error occurred |
| |
| 2: Malformed command line |
| |
| 3: No Interests received before the timeout |
| |
| 5: Prefix registration failed |
| |
| Example |
| ------- |
| |
| Create a Data packet with content ``hello`` and name ``/app/video`` and wait at |
| most 3 seconds for a matching Interest to arrive:: |
| |
| echo "hello" | ndnpoke -w 3000 /app/video |
