Is there a way to send a continuous stream from a command output to a remote listener
提问by Sushant Khurana
I'm using the netcat for unix.
我正在为 unix 使用 netcat。
when I run python script.py &> logfile.txt, it gets captured continuously.
当我运行时python script.py &> logfile.txt，它会不断被捕获。
To replicate this remotely, I tried nc -l -p 8011on the listener (client) and the following for the sender (host or server) :
为了远程复制这个，我尝试nc -l -p 8011了侦听器（客户端）和发件人（主机或服务器）的以下内容：
python script.py &> nc 127.0.0.1 8011python script.py > nc 127.0.0.1 8011nc 127.0.0.1 8011 < python script.py
python script.py &> nc 127.0.0.1 8011python script.py > nc 127.0.0.1 8011nc 127.0.0.1 8011 < python script.py
But nothing seems to work. Please help.
但似乎没有任何效果。请帮忙。

Is this what you're after?
这是你追求的吗？
Receiver:
接收者：
nc -l 8011 >logfile.txt
Sender:
发件人：
python script.py 2>&1 | nc 127.0.0.1 8011
Make sure to run the receiver code first.
确保首先运行接收器代码。
EDIT: In case you're not aware there's a lot of different versions of netcat; they all accept slightly different arguments (e.g. nc.traditionalon Debian wants nc -l -p 1234to listen on port 1234, whereas BSD nc(e.g. OS X) just wants nc -l 1234and ncatmay throw an interesting error unless you use the -4flag if your host doesn't support IPv6) - read the man pages to find out what combination of options you actually want.
编辑：如果您不知道有很多不同版本的 netcat；它们都接受略有不同的参数（例如nc.traditional在 Debian 上想要nc -l -p 1234监听端口 1234，而 BSD nc（例如 OS X）只是想要nc -l 1234并且ncat可能会抛出一个有趣的错误，除非您在-4主机不支持 IPv6 的情况下使用该标志） - 阅读 man页面以找出您真正想要的选项组合。

Perfect answer, with one slight modification: adding -pfor "port"
完美答案，稍加修改：为“端口”添加-p
Receiver:
接收者：
nc -l -p 8011 >logfile.txt
I pulled in the nc help file ( nc -h) using your suggestion
我使用您的建议提取了 nc 帮助文件 (nc -h)
Sender:
发件人：
nc -h 2>&1 | nc 127.0.0.1 8011
I tried
我试过
nc -h > logfile.txt
nc -h >> logfile.txt
which never worked.
这从未奏效。
