Foreword
In reference to the use of the Internet for remote connection SSHD and ngrok Google colab , with particular reference to Gist. If you do not like the web colab work environment, as well as shell commands to add special symbols, refer to this article, pro-test.
step
1. Go to google cloud create a disk file colaboratory jupyter
2. Set created .ipynb file, select Python3
Click on the menu bar Edit -> Notebook settings, select Pyt hon3, GPU and so on. Python2 course also possible only to change the code below.
3. Run the script to generate host and password
The following code is a copy of the cell ipynb, ctrl + enter operation cell,
import random, string, urllib.request, json, getpass #Generate root password password = ''.join(random.choice(string.ascii_letters + string.digits) for i in range(20)) #Download ngrok ! wget -q -c -nc https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip ! unzip -qq -n ngrok-stable-linux-amd64.zip #Setup sshd ! apt-get install -qq -o=Dpkg::Use-Pty=0 openssh-server pwgen > /dev/null #Set root password ! echo root:$password | chpasswd ! mkdir -p /var/run/sshd ! echo "PermitRootLogin yes" >> /etc/ssh/sshd_config ! echo "PasswordAuthentication yes" >> /etc/ssh/sshd_config ! echo "LD_LIBRARY_PATH=/usr/lib64-nvidia" >> /root/.bashrc ! echo "export LD_LIBRARY_PATH" >> /root/.bashrc #Run sshd get_ipython().system_raw('/usr/sbin/sshd -D &') #Ask token print("Copy authtoken from https://dashboard.ngrok.com/auth") authtoken = getpass.getpass() #Create tunnel get_ipython().system_raw('./ngrok authtoken $authtoken && ./ngrok tcp 22 &') #Get public address and print connect command with urllib.request.urlopen('http://localhost:4040/api/tunnels') as response: data = json.loads(response.read().decode()) (host, port) = data['tunnels'][0]['public_url'][6:].split(':') print(f'SSH command: ssh -p{port} root@{host}') #Print root password print(f'Root password: {password}')
运行过程中会提示输入 ngrok 生成的 authtoken，如下图，
点击生成的连接进入，copy authtoken，粘贴进提示框，如果没有注册 ngrok 的需先注册，cell 继续运行，最终的输出类似于：
Copy authtoken from https://dashboard.ngrok.com/auth ·········· SSH command: ssh -p19483 root@0.tcp.ngrok.io Root password: G9azUpC7XmDkNyXg***
4. 在个人 pc 端 ssh 连接
输入下面的命令，对应的 port 和 password 根据上面的生成的为例，'19483' 为端口号
ssh -p19483 root@0.tcp.ngrok.io
可以看到 colab 提供的免费显卡
nvidia-smi
此外想挂载 google 云盘到 colab，则上面的 ipynb 文件中添加一个 cell，运行下面代码
from google.colab import drive drive.mount('/content/drive/')
则可以在远程连接的 colab 中的 /content/drive/ 路径中看到网路云盘的内容。
