一、监控鼠标键盘设备

#include <sys/types.h>
#include <fcntl.h>
#include <stdlib.h>
#include <time.h>
#include <stdio.h>
#include <unistd.h>
#include <linux/input.h>
#include <pthread.h>
#include <time.h>
#include <string.h>
#include <errno.h>struct timespec ts1, ts2;int listen_keyboard(const char *dev, int timeout)
{int retval;fd_set readfds;struct timeval tv;struct input_event event;int fd = open(dev, O_RDONLY);if (fd < 0){return errno;}while (1){FD_ZERO(&readfds);FD_SET(fd, &readfds);tv.tv_sec = timeout;tv.tv_usec = 0;if((retval = select(fd+1, &readfds, NULL, NULL, &tv)) == 1){if (read(fd, &event, sizeof(event)) == sizeof(event)){clock_gettime(CLOCK_REALTIME, &ts1);return 0;} else {return 0;}}else{break;}}close(fd);return 0;
}int listen_mice(const char *dev, int timeout)
{char buf[256];int n_len;int retval;fd_set readfds;struct timeval tv;int fd = open(dev, O_RDONLY);if (fd < 0){return errno;}while (1){FD_ZERO(&readfds);FD_SET(fd, &readfds);tv.tv_sec = timeout;tv.tv_usec = 0;if((retval = select(fd+1, &readfds, NULL, NULL, &tv)) == 1){if ((n_len = read(fd, buf, sizeof(buf))) > 0){if (n_len == 3){clock_gettime(CLOCK_REALTIME, &ts1);return 0;}}}else{break;}}close(fd);return 0;
}void * mon_key(void *arg)
{int ret;char *path = (char *)arg;while(1) {ret = listen_keyboard(path, 3600);if (ret != 0) {exit(-1);}}
}void * mon_mouse(void *arg)
{while(1) {listen_mice("/dev/input/mice", 3600);}
}int main(int argc, char **argv)
{pthread_t id[10];int i;char apath[100];char *bpath[i];FILE *fp;clock_gettime(CLOCK_REALTIME, &ts1);clock_gettime(CLOCK_REALTIME, &ts2);fp = popen("ls /dev/input/by-path |grep kbd", "r");if (fp == NULL){printf("popen failed\n");return -1;}i=0;while (fgets(apath, sizeof(apath), fp)) {bpath[i] = malloc(200);apath[strlen(apath) - 1] = '\0';sprintf(bpath[i], "/dev/input/by-path/%s", apath);pthread_create(&id[i], NULL, &mon_key, bpath[i]);i++;}pclose(fp);pthread_create(&id[i++], NULL, &mon_mouse, NULL);while(1) {sleep(1);clock_gettime(CLOCK_REALTIME, &ts2);printf("idletime %ld\n", ts2.tv_sec - ts1.tv_sec);}return 0;
}

二、使用pynput监控鼠标键盘事件

#!/usr/bin/python3
'''
apt install python3-dev
apt install pip
pip3 install pynput
'''from pynput.keyboard import Key as kbKey, Listener as kbListener
from pynput.mouse import  Listener as msListener
import threading
import time
import datetime
import osupdateDatetime = datetime.datetime.now()
currentDatetime = datetime.datetime.now()'''
关于键盘的事件回调
'''
#defining function to print when key is pressed
def on_press(key):global updateDatetimeupdateDatetime = datetime.datetime.now()print('{0} pressed'.format(key))#defining function to print when key is released
def on_release(key):global updateDatetimeupdateDatetime = datetime.datetime.now()print('{0} release'.format(key))'''
关于鼠标及触控的事件回调
'''
def on_move(x, y ):global updateDatetimeupdateDatetime = datetime.datetime.now()print('Pointer moved to {0}'.format((x,y)))def on_click(x, y , button, pressed):global updateDatetimeupdateDatetime = datetime.datetime.now()print('{0} at {1}'.format('Pressed' if pressed else 'Released', (x, y)))def on_scroll(x, y ,dx, dy):global updateDatetimeupdateDatetime = datetime.datetime.now()print('scrolled {0} at {1}'.format('down' if dy < 0 else 'up',(x, y)))'''
键盘的事件监控
'''
def toListenerKb(threadName):# # Collect events until releasedwhile True:with kbListener(on_press=on_press,on_release=on_release) as listener:listener.join()'''
鼠标的事件监控
'''
def toListenerMouse(threadName):while True:with msListener(on_move = on_move,on_click = on_click,on_scroll = on_scroll) as listener:listener.join()if __name__ == '__main__':threads = []t1 = threading.Thread( target=toListenerKb , args=("Listener keyBoard", ))t2 = threading.Thread( target=toListenerMouse , args=("Listener Mouse", ))threads.append(t1)threads.append(t2)for t in threads:t.setDaemon(True)t.start()while True:currentDatetime = datetime.datetime.now()sub = currentDatetime - updateDatetimetime.sleep(1)# 30s 没有操作就杀死远程if sub.seconds > 30:os.system("ps -ef | grep remmina | grep -v grep; if [ $? -eq 0 ]; then killall -9 remmina; fi")print('空闲时间： {0}秒'.format(sub.seconds))

三、使用X11的extensions监控鼠标键盘事件

3.1 使用Python的python3-xlib库进行监控

#!/usr/bin/python3'''
apt install python3-xlibSimple demo for the RECORD extension
Not very much unlike the xmacrorec2 program in the xmacro package.
'''
# apt install python3-xlib# Python 2/3 compatibility.
from __future__ import print_functionimport sys
import threading
import time
import datetime
import osfrom Xlib import X, XK, display
from Xlib.ext import record
from Xlib.protocol import rqupdateDatetime = datetime.datetime.now()
currentDatetime = datetime.datetime.now()local_dpy = display.Display()
record_dpy = display.Display()# Check if the extension is present
if not record_dpy.has_extension("RECORD"):print("RECORD extension not found")sys.exit(1)
r = record_dpy.record_get_version(0, 0)
print("RECORD extension version %d.%d" % (r.major_version, r.minor_version))# Create a recording context; we only want key and mouse events
ctx = record_dpy.record_create_context(0,[record.AllClients],[{'core_requests': (0, 0),'core_replies': (0, 0),'ext_requests': (0, 0, 0, 0),'ext_replies': (0, 0, 0, 0),'delivered_events': (0, 0),'device_events': (X.KeyPress, X.MotionNotify),'errors': (0, 0),'client_started': False,'client_died': False,}])def lookup_keysym(keysym):for name in dir(XK):if name[:3] == "XK_" and getattr(XK, name) == keysym:return name[3:]return "[%d]" % keysymdef record_callback(reply):'''回调函数'''if reply.category != record.FromServer:returnif reply.client_swapped:print("* received swapped protocol data, cowardly ignored")returnif not len(reply.data) or reply.data[0] < 2:# not an eventreturnglobal updateDatetimedata = reply.datawhile len(data):event, data = rq.EventField(None).parse_binary_value(data, record_dpy.display, None, None)if event.type in [X.KeyPress, X.KeyRelease]:updateDatetime = datetime.datetime.now()pr = event.type == X.KeyPress and "Press" or "Release"keysym = local_dpy.keycode_to_keysym(event.detail, 0)if not keysym:print("KeyCode%s" % pr, event.detail)else:print("KeyStr%s" % pr, lookup_keysym(keysym))if event.type == X.KeyPress and keysym == XK.XK_Escape:local_dpy.record_disable_context(ctx)local_dpy.flush()returnelif event.type == X.ButtonPress:updateDatetime = datetime.datetime.now()print("ButtonPress", event.detail)elif event.type == X.ButtonRelease:updateDatetime = datetime.datetime.now()print("ButtonRelease", event.detail)elif event.type == X.MotionNotify:updateDatetime = datetime.datetime.now()print("MotionNotify", event.root_x, event.root_y)def monitor(threadName):'''线程函数'''# Enable the context; this only returns after a call to record_disable_context,# while calling the callback function in the meantimerecord_dpy.record_enable_context(ctx, record_callback)# Finally free the contextrecord_dpy.record_free_context(ctx)if __name__ == '__main__':t = threading.Thread(target=monitor, args=("Listener", ))t.setDaemon(True)t.start()while True:currentDatetime = datetime.datetime.now()sub = currentDatetime - updateDatetimetime.sleep(1)print('空闲时间： {0}秒'.format(sub.seconds))

3.2 使用c调用X11的extensions库进行监控

// apt install xorg-dev
// 编译：gcc xrecord_monitor.c -lX11 -lXtst -lpthread -o xrecord_monitor
// sudo apt-get install xorg-dev
// gcc xrecord_monitor.c -lX11 -lXtst -lpthread -o xrecord_monitor
#include <stdio.h>
#include <unistd.h>
#include <X11/Xlib.h>
#include <X11/Xproto.h>
#include <X11/extensions/record.h>
#include <time.h>
#include <pthread.h>time_t updateTime,currentTime;static void event_cb (XPointer user_data, XRecordInterceptData *hook)
{if ( hook->category != XRecordFromServer ) {printf ("Data not from server!");return;}xEvent * event = (xEvent *)hook->data; switch (event->u.u.type) {case KeyPress:updateTime = time(NULL);printf ("key press event! \n");break;case KeyRelease:updateTime = time(NULL);printf ("key release event! \n");break;case ButtonPress:updateTime = time(NULL);printf ("button press event! x = %d, y = %d\n", event->u.keyButtonPointer.rootX, event->u.keyButtonPointer.rootY);break;case ButtonRelease:updateTime = time(NULL);printf ("button release event! x = %d, y = %d\n", event->u.keyButtonPointer.rootX, event->u.keyButtonPointer.rootY);break;case MotionNotify:updateTime = time(NULL);printf ("mouse move event! x = %d, y = %d\n", event->u.keyButtonPointer.rootX, event->u.keyButtonPointer.rootY);break;default:updateTime = time(NULL);printf ("other events grab \n");/* FIXME: other events grab */break;}
}void * monitor(void *arg)
{Display *ctrl_disp = XOpenDisplay(NULL);Display *data_disp = XOpenDisplay(NULL);if ( !ctrl_disp || !data_disp ) {fprintf (stderr,"Unable to connect to X11 display! \n");return NULL;}int major, minor, dummy;if ( !XQueryExtension (ctrl_disp, "XTEST", &major, &minor, &dummy) ) {fprintf (stderr,"XTest extension missing! \n");return NULL;}if ( !XRecordQueryVersion (ctrl_disp, &major, &minor) ) {fprintf (stderr,"Failed to obtain xrecord version! \n");return NULL;}XSynchronize(ctrl_disp, True);XFlush (ctrl_disp);XRecordRange *range = XRecordAllocRange ();/** 设定事件监听的范围* 监听 first ~ last 之间的事件*/range->device_events.first = KeyPress;range->device_events.last = LASTEvent;XRecordClientSpec spec = XRecordAllClients;XRecordContext context = XRecordCreateContext (data_disp, 0, &spec, 1, &range, 1 );if ( !context ) {fprintf (stderr,"Failed to create context! \n");return NULL;}if ( !XRecordEnableContext(data_disp, context, event_cb, NULL) ) {fprintf (stderr,"Failed to enable context! \n");return NULL;}XRecordDisableContext(data_disp, context);XRecordFreeContext (data_disp, context);XFree(range);XCloseDisplay (data_disp);XCloseDisplay (ctrl_disp);return NULL;
}int main (int argc, char *argv[])
{pthread_t tid;pthread_create(&tid, NULL, &monitor, NULL);while(1) {sleep(1);currentTime = time(NULL);printf("idle time %ld s\n", currentTime - updateTime);}return 0;
}
