def detect_attack with openclientstxt r as f clients = freadlines for client in clients ip = clientsplit0 mac = clientsplit1 sniff_filter = arp and sr

To achieve the functionality of only displaying the detection result once and returning to the main interface, you can modify the code as follows:

1. Add a flag variable to indicate whether an attack has been detected:

def detect_attack():
    with open("clients.txt", "r") as f:
        clients = f.readlines()
        attack_detected = False  # flag variable
        for client in clients:
            ...

2. If an attack is detected, set the flag to True and break out of the loop:

if sniff_count > 100:
    attack_detected = True
    messagebox.showwarning("警告", "检测到攻击源IP地址为" + ip + "，MAC地址为" + mac + "！")
    with open("detection_log.txt", "a") as f:
        f.write("警告"+ "检测到攻击源IP地址为" + ip + "，MAC地址为" + mac + "！\n")
    break  # break out of the loop

3. After the loop, check the flag and display the appropriate message:

if attack_detected:
    messagebox.showwarning("警告", "检测到攻击源！")
else:
    messagebox.showinfo("提示", "未检测到攻击源！")
with open("detection_log.txt", "a") as f:
    f.write("检测结果：" + ("检测到攻击源！" if attack_detected else "未检测到攻击源！") + "\n")

With these modifications, the code will only display the detection result once and return to the main interface
