我有以下用 2.7 python 编写的代码:

#...import stuff

remoteServer = raw_input("Enter a remote host to scan: ")
remoteServerIP = socket.gethostbyname(remoteServer)

print "Please wait, scanning remote Host", remoteServerIP

try:
    for port in xrange(1, 1024):
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        result = sock.connect_ex((remoteServerIP, port))
        if result == 0:
            print "port {}:    open".format(port)
        sock.close

except KeyboardInterrupt:
    print "\nexiting..."
    sys.exit()

输出:
Enter a remote host to scan: www.myexamplesite.com
Please wait, scanning remote Host xxx.xxx.xx.xx
port 21:    open
port 22:    open
...

但问题是我也想知道使用了哪些端口以及它们的用途,就像:



但这只是打印从 1 到 1024 的端口
有没有功能/方法可以做到这一点?

最佳答案

socket.getservbyport() 会将端口号转换为预期在该端口上运行的服务(通过 /etc/services ),但实际上不会通过端口进行通信以找出真正在运行的内容。

关于python - 打印端口及其名称,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/47003908/
