Lua/NSE套接字连接问题
我可以毫无问题地远程登录到某个主机和端口并发出命令。但是，当我尝试编写与同一主机和端口的套接字连接（使用 nmap NSE 和 Lua）脚本时，它失败并显示以下错误消息：
|_sockettest：尝试通过关闭的套接字接收
套接字我的代码的连接部分在这里：
local msg
local response
msg = "hello\n"
local socket = nmap.new_socket()
socket:set_timeout(150000)
socket:send(msg)
response,data = socket:receive()
return data
我认为数据发送正常。服务器应该只回显我发送的内容。有谁知道问题可能是什么？
I can telnet to a certain host and port no problem and issue commands. However when i try to script a socket connection (using nmap NSE and Lua) to the same host and port, it fails with the following error message:
|_sockettest: Trying to receive through a closed socket
the socket connect part of my code is here:
local msg
local response
msg = "hello\n"
local socket = nmap.new_socket()
socket:set_timeout(150000)
socket:send(msg)
response,data = socket:receive()
return data
I think the data is sending ok. The server should just echo back what i sent. Does anyone know what the problem could be?

您需要在接收之前（以及发送之前）调用
socket:connect。说真的，请阅读您编写的代码。 您指定的发送对象是哪里？You need to call
socket:connectbefore receiving (and before sending). Seriously, read that code you wrote. Where did you specify to whom you're sending ?
