Hey everyone! As a professional programmer, today I want to share with you a solution to quickly switch proxy settings in the Linux terminal. If you often encounter the problem of being unable to access a specific website due to network blockage, then this article will bring you practical operational value. Let's discover together how to easily switch proxy settings in the Linux terminal!
Problem background:
In some cases, we may need to use a proxy server to access blocked or restricted websites. However, changing proxy settings manually can be tedious, especially if you need to switch proxies frequently. Therefore, we need a simple and efficient way to quickly switch proxy settings.
solution:
In the Linux terminal, we can use environment variables and some command line tools to quickly switch proxy settings. Here are some steps to help you easily deal with internet blockades in the Linux terminal:
Step 1: Install the necessary tools
First, make sure you have installed proxychainsand proxychains-ngthese two tools. They are command line tools for implementing proxy settings in the terminal. You can use package management tools to install.
```
sudo apt-get install proxychains
```
Step 2: Configure proxy server
In your terminal, edit /etc/proxychains.confthe file to configure your proxy server information. You can add the following at the end of the file:
```
[ProxyList]
#Format: [proxy type] [proxy IP address] [proxy port number] [proxy user name] [proxy password]
socks5 127.0.0.1 1080
```
Modify the proxy type, IP address and port number according to your actual situation. You can also add a username and password if the proxy server requires authentication.
Step 3: Switch proxy settings
Now, you can use proxychainsthe command to toggle the proxy settings in the terminal. Here are some examples of commonly used commands:
- Use a proxy to access specific commands: proxychains<command>, for example:proxychains wget https://example.com
- start a new terminal session and automatically use the proxy: proxychains<terminal>, eg:proxychains gnome-terminal
With these commands, you can quickly switch proxy settings in the terminal and access blocked websites.
Complete code example:
```bash
# install proxychains
sudo apt-get install proxychains
#Configure proxy server
sudo nano/etc/proxychains.conf
#Add the following at the end of the file
[ProxyList]
#Format: [proxy type] [proxy IP address] [proxy port number] [proxy user name] [proxy password]
socks5 127.0.0.1 1080
# Use a proxy to access specific commands
proxychains wget https://example.com
# start a new terminal session and automatically use the proxy
proxychains gnome-terminal
```
Summarize:
By using environment variables and command-line tools in the Linux terminal, we can easily switch proxy settings to deal with network blocking problems. Not only is this method simple and efficient, but it also has practical value and can help you access blocked websites more easily. Hope this article helps you!
