I am trying to run the script. But when I pass an IP which is not in the network to the s.connect() function. It dosen’t respond, the script goes on hold, so I want to end the check on IP, if the Ip is not found in the network. Does anyone have an idea, on how to proceed.

`import socket
def getBanner(ip,port):
    socket.setdefaulttimeout(1)
    if(s.connect((ip,port))):
        banner = s.recv(1024).decode()
        return banner
    else:
        return "Nothing"

def main():
    ip = "192.168.152."+str(0)
    banner = getBanner(ip,21)
    print(banner)

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
main()`
