dev/rfkill 및 PyRIC 라이브러리, rfkill.py: rfkill_list() 문제가 모든 장치를 찾을 수 없음

나는 코드 조각을 가지고 놀고 있습니다.https://github.com/wraith-wireless/PyRIC/blob/master/pyric/utils/rfkill.py, 얻으려고 노력 중rfkill_list()

Kali-linux 사용(데비안 롤링이어야 합니다...??)

 https://github.com/wraith-wireless/PyRIC/blob/master/pyric/utils/rfkill.py

 rfkill writes and reads rfkill_event structures to /dev/rfkill using fcntl
 Results and useful information can be found in /sys/class/rfkill which contains
 one or more rfkill<n> directories where n is the index of each 'wireless'
 device. In each rfkill<n> are several files some of which are:
  o type: type of device i.e. wlan, bluetooth etc
  o name: in the case of 802.11 cards this is the physical name

이에 대해 잘 모르겠지만 모든 무선 인터페이스가 포함된 사전을 인쇄하는 코드를 원합니다 rfkill list.

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: phy1: Wireless LAN
        Soft blocked: no
        Hard blocked: no
2: phy2: Wireless LAN
        Soft blocked: no
        Hard blocked: no

하지만 (위에서 언급한 대로) 내 스크립트를 실행하면 다음과 같은 결과가 나옵니다.

{'phy0': {'idx': 0, 'type': 'wlan', 'soft': False, 'hard': False}}

에 따르면:https://github.com/torvalds/linux/blob/master/include/uapi/linux/rfkill.h

* Structure used for userspace communication on /dev/rfkill,
 * used for events from the kernel and control to the kernel.

struct rfkill_event {
    __u32 idx;
    __u8  type;
    __u8  op;
    __u8  soft;
    __u8  hard;
} __attribute__((packed));

그리고 내 스크립트는 스트림으로 제공됩니다.

stream :  <class 'str'>  len ;  8 b'\x00\x00\x00\x00\x01\x00\x00\x00'
stream :  <class 'str'>  len ;  8 b'\x00\x01\x00\x00\x00\x01\x00\x00'
stream :  <class 'str'>  len ;  8 b'\x00\x00\x02\x00\x00\x00\x01\x00'

dev/rfkill그리고 다른 스크립트를 사용하여 내가 얻는 전체를 읽습니다 .

len stream decoded : --->  27
b'\x00\x00\x00\x00\x01\x00\x00\x00\x00\x01\x00\x00\x00\x01\x00\x00\x00\x00\x02\x00\x00\x00\x01\x00\x00\x00\x00'

내가 뭐 놓친 거 없니? 이것이 예상된 결과입니까? phy0, phy1 및 phy2를 동시에 얻지 못하는 이유는 무엇입니까?

그것은 모든 것처럼 보입니다 phy#.

내가 읽는 방식이 dev/rfill잘못된 걸까?

내 코드에 어떤 문제가 있는지 알려주세요.

코드 정보:

rfk_rfkill_event = "IBBBB"  #(that should be the same of "@IBBBB" )
RFKILLEVENTLEN = struct.calcsize(rfk_rfkill_event)    

안에 들어 있는 게 바로 이거야rfkh.RFKILLEVENTLEN
