SSH Tunnel

准备VM

创建一个azure linux vm, ./ssh/config示例:

Host vm1
    HostName xx.xx.xx.xx
    User L001
    IdentityFile azure001_key.pem
    Compression yes
    DynamicForward 1080
    ServerAliveCountMax 60
    ServerAliveInterval 30

设置代理

火狐浏览器

火狐浏览器中，网址栏输入"about:preferences"，随后下拉至最下方"网络设置"-->"设置"-->"手动配置代理"
1

所有浏览器(Win10)

网络设置-->连接
2
然后此处会显示
3
注意，不能直接搜索代理、然后设置，否则不生效

链接

保持与vm的链接，正常使用(火狐)浏览器就行了

ssh -vvv vm1

查看IP

vm中: 

## 外网
curl ifconfig.me
curl cip.cc
## 内网？
ip route show

看下浏览器访问ifconfig.me是否已经变为远程地址

Python SSH Tunnel

比方说链接SQL数据库啥的

Install Packages

sudo apt-get update
sudo apt install python3-pip
python3 -m pip install sshtunnel

ssh-keygen              ## /home/L001/.ssh/id_rsa

Example

from sshtunnel import SSHTunnelForwarder

server = SSHTunnelForwarder(
    SSH_SERVER,                             #Step 2 连接远端服务器SSH端口
    ssh_username=USERNAME,
    ssh_password=USERPWD,
    local_bind_address=LOCAL_ADDR,          #Step 1 连接本地地址，若不配置则随机绑定
    remote_bind_address=REMOTE_ADDR)        #Step 3 跳转到远端服务器

server.start()

print(server.local_bind_port)
