ftpd FTP daemon

This example exercises the FTPD daemon at apps/netutils/ftpd. Below are configurations specific to the FTPD example (the FTPD daemon itself may require other configuration options as well).

  • CONFIG_EXAMPLES_FTPD – Enable the FTPD example.

  • CONFIG_EXAMPLES_FTPD_PRIO – Priority of the FTP daemon. Default: SCHED_PRIORITY_DEFAULT.

  • CONFIG_EXAMPLES_FTPD_STACKSIZE – Stack size allocated for the FTP daemon. Default: 2048.

  • CONFIG_EXAMPLES_FTPD_NONETINIT – Define to suppress configuration of the network by apps/examples/ftpd. You would need to suppress network configuration if the network is configuration prior to running the example.

NSH always initializes the network so if CONFIG_NSH_NETINIT is defined, so is CONFIG_EXAMPLES_FTPD_NONETINIT (se it does not explicitly need to be defined in that case):

  • CONFIG_NSH_BUILTIN_APPS – Build the FTPD daemon example test as an NSH built-in function. By default the FTPD daemon will be built as a standalone application.

If CONFIG_EXAMPLES_FTPD_NONETINIT is not defined, then the following may be specified to customized the network configuration:

  • CONFIG_EXAMPLES_FTPD_NOMAC – If the hardware has no MAC address of its own, define this =y to provide a bogus address for testing.

  • CONFIG_EXAMPLES_FTPD_IPADDR – The target IP address. Default 10.0.0.2.

  • CONFIG_EXAMPLES_FTPD_DRIPADDR – The default router address. Default: 10.0.0.1.

  • CONFIG_EXAMPLES_FTPD_NETMASK – The network mask. Default: 255.255.255.0.

TCP networking support is required. So are pthreads so this must be set to ‘n’:

  • CONFIG_DISABLE_PTHREAD – pthread support is required.

Other FTPD configuration options they may be of interest:

  • CONFIG_FTPD_VENDORID – The vendor name to use in FTP communications. Default: NuttX.

  • CONFIG_FTPD_SERVERID – The server name to use in FTP communications. Default: NuttX FTP Server.

  • CONFIG_FTPD_CMDBUFFERSIZE – The maximum size of one command. Default: 512 bytes.

  • CONFIG_FTPD_DATABUFFERSIZE – The size of the I/O buffer for data transfers. Default: 2048 bytes.

  • CONFIG_FTPD_WORKERSTACKSIZE – The stacksize to allocate for each FTP daemon worker thread. Default: 2048 bytes.

The following netutils libraries should be enabled in your defconfig file:

CONFIG_NETUTILS_NETLIB=y
CONFIG_NETUTILS_FTPD=y
