可使用busybox內建的nc指命傳送檔案

nc example (由pc listen，板端送出資料)

  • 先開啟本機的listen port
1
nc -l 6000 > image_info
  • 於板端開啟傳送
1
nc mypc.com 6000 < image_info

nc example 2 (由 板端 listen，pc接受資料)

  • 板端 (ip: a.b.c.d)

    1
    nc -l -p 6666 < file

  • pc

    1
    nc a.b.c.d 6666 > file

板端 nc command

    Options:

            -i SEC  Delay interval for lines sent
            -w SEC  Timeout for connect
            -f FILE Use file (ala /dev/ttyS0) instead of network
            -l      Listen mode, for inbound connects
                    (use -l twice with -e for persistent server)
