问题描述

我使用以下方式登录到 HPC:

ssh -p 2222 user@hpc.edu

然后使用以下命令启动 Jupyter notebook:

jupyter notebook --no-browser --port=9999

我有一个网址:

http://localhost:9999/?token=0518475c55eaafb82abce7d2d5344b48174012

然后我尝试使用我的计算机远程访问 Jupyter notebook:

ssh -p 2222 user@hpc.edu -L 9999:localhost:9999 -N

连接很长时间后被拒绝:

channel 2: open failed: connect failed: Connection refused

我记得早些时候能够通过不放

-p 2222 

在任何地方的 ssh 命令中。但现在我必须这样做才能远程 ssh。远程访问 jupyter notebook 是否需要任何其他命令更改?

编辑:

我将 -v -v 添加到我在计算机上执行的命令中。这是它所说的:

解决方案


这个对我有用。首先,使用以下命令从您的服务器启动 Jupyter:

jupyter notebook --no-browser --port=7002

然后从您的本地计算机,您可以使用以下代码隧道到 Jupyter

ssh -N -f -L localhost:7001:localhost:7002 user@hpc.edu

现在您可以通过浏览从本地计算机访问 Jupyterlocalhost:7001
