## USAGE ##
|
|
|
|
Usage is straightforward:
|
|
|
|
nsh> help ; netcat
|
|
Usage: netcat [-l] [destination] [port] [file]
|
|
|
|
nsh> renew eth0 ; ifconfig
|
|
|
|
eth0 Link encap:Ethernet HWaddr 52:13:FF:FF:FF:FF at UP
|
|
inet addr:192.168.1.42 DRaddr:192.168.1.254 Mask:255.255.255.0
|
|
|
|
In the following examples, following configuration is used:
|
|
|
|
- target (nuttx) is 192.168.1.42
|
|
- host (linux) is 192.168.1.55
|
|
|
|
### Server ###
|
|
|
|
As a server on NuttX and Linux's netcat as client
|
|
|
|
nsh> netcat -l
|
|
|
|
sh> cat /proc/version | netcat 192.168.1.42 31337
|
|
Linux ...
|
|
|
|
Default port is 31337 but it can changed.
|
|
|
|
nsh> renew eth0 ; ifconfig ; netcat -l
|
|
log: net: listening on :31337
|
|
Linux ...
|
|
|
|
### Client ###
|
|
|
|
Start Server on GNU/Linux:
|
|
|
|
sh> ip addr show && netcat -l 31337
|
|
|
|
Client side on nuttx, we create
|
|
|
|
nsh> help ; renew eth0 ; ifconfig
|
|
nsh> netcat 192.168.1.55 31337 /proc/version
|
|
|
|
### Using pipes ###
|
|
|
|
mkfifo /dev/fifo
|
|
netcat 192.168.1.55 31337 /proc/fifo
|
|
help > /dev/fifo
|
|
|
|
fxos8700cq > /dev/fifo &
|
|
fxos8700cq [7:100]
|
|
netcat 192.168.1.55 31337 /dev/fifo
|
