To install and set up Shadowsocks server on Termux with support for both TCP and UDP, follow these steps:

1. Install Dependencies

First, you’ll need to install the required dependencies in Termux.

Open Termux and run the following commands to update packages and install the necessary dependencies:

bash

Copy code

pkg update pkg install python python-dev clang make git

2. Install Shadowsocks Server

You can install Shadowsocks using Python since it’s available via pip (Python’s package manager). Run the following command:

bash

Copy code

pip install shadowsocks

3. Configure Shadowsocks

Once installed, you can configure the Shadowsocks server by creating a configuration file.

  1. Create a directory for Shadowsocks configuration:

    bash

    Copy code

    mkdir -p ~/shadowsocks cd ~/shadowsocks

  2. Create a configuration file named config.json:

    bash

    Copy code

    nano config.json

    Add the following configuration to the config.json file:

    json

    Copy code

    { "server": "0.0.0.0", # Listen on all interfaces "server_port": 1080, # You can choose another port "local_address": "127.0.0.1", "local_port": 1080, # Local port for the client "password": "your_password_here", # Set your password "timeout": 300, "method": "aes-256-cfb", # Encryption method, can choose other options "fast_open": false, "workers": 1 }

    Replace "your_password_here" with a secure password of your choice.

4. Run the Shadowsocks Server

After configuring, run the Shadowsocks server with the following command:

bash

Copy code

ssserver -c ~/shadowsocks/config.json

This will start the Shadowsocks server and it will be listening on port 1080 (or whatever port you configured). The server will support both TCP and UDP traffic.

5. Verify UDP Support

Shadowsocks supports UDP traffic by default through its protocol. You don’t need additional configuration to enable UDP. To test UDP traffic, you can use a compatible Shadowsocks client (on Android, PC, etc.) that is configured to use the same server settings.

6. Optional: Run Shadowsocks Server in the Background

If you want to run the Shadowsocks server in the background, use nohup or tmux:

Using nohup:

bash

Copy code

nohup ssserver -c ~/shadowsocks/config.json &

Or using tmux:

bash

Copy code

tmux new-session -d -s shadowsocks 'ssserver -c ~/shadowsocks/config.json'

7. Firewall / NAT Settings

If you’re running this server on an Android device, make sure that any firewall or NAT (Network Address Translation) settings allow traffic to pass through the port you’ve chosen (1080 or any other custom port). You might also need to configure port forwarding if running this in a network with a router.

This setup will allow you to run a Shadowsocks server on your Android device (via Termux), and it will support both TCP and UDP connections.

Let me know if you encounter any issues during installation or setup!

The error you’re seeing (AttributeError: module 'collections' has no attribute 'MutableMapping') is caused by a change in Python 3.10 and later, where MutableMapping was moved from collections to collections.abc.

To fix this issue, you can edit the Shadowsocks source code or modify the dependencies to be compatible with the version of Python you’re using.

Option 1: Modify the lru_cache.py File

You can directly modify the lru_cache.py file in the Shadowsocks source code to make it compatible with Python 3.10+.

  1. Open the lru_cache.py file in the Shadowsocks directory:

    bash

    Copy code

    nano /data/data/com.termux/files/usr/lib/python3.12/site-packages/shadowsocks/lru_cache.py

  2. In the lru_cache.py file, look for the line where MutableMapping is imported from collections. It will look like this:

    python

    Copy code

    from collections import MutableMapping

  3. Change it to:

    python

    Copy code

    from collections.abc import MutableMapping

  4. Save and close the file (CTRL + X, then press Y and Enter to confirm).

Option 2: Reinstall Shadowsocks with Python 3.9 or Lower

If modifying the file doesn’t resolve the issue or you prefer an easier approach, you could try using Python 3.9 or lower. To install an older version of Python on Termux:

  1. Uninstall the current Python version:

    bash

    Copy code

    pkg uninstall python

  2. Install Python 3.9:

    bash

    Copy code

    pkg install python3.9

  3. Then reinstall Shadowsocks using the older Python version:

    bash

    Copy code

    pip install shadowsocks

  4. Try running the server again with:

    bash

    Copy code

    ssserver -c ~/shadowsocks/config.json

Option 3: Use a Shadowsocks Package from a Different Source

Alternatively, you could try using a precompiled version of Shadowsocks from a repository that supports your version of Python.

It looks like the issue is persisting even after modifying the lru_cache.py file, indicating that there might still be other places in the Shadowsocks code where collections.MutableMapping is used.

To fully resolve this, let’s search for all instances of MutableMapping in the Shadowsocks code and update them to use collections.abc.MutableMapping instead. Here’s how you can proceed:

Steps to Fix the Issue:

  1. Search for all MutableMapping references:

    You can search through the Shadowsocks code to find all occurrences of MutableMapping and update them to collections.abc.MutableMapping.

    Run this command in Termux to find all occurrences:

    bash

    Copy code

    grep -r "MutableMapping" /data/data/com.termux/files/usr/lib/python3.12/site-packages/shadowsocks/

  2. Edit the necessary files:

    For each file that contains the reference to MutableMapping, you need to change the import from collections to collections.abc. For example:

    • Before:

      python

      Copy code

      from collections import MutableMapping

    • After:

      python

      Copy code

      from collections.abc import MutableMapping

    You can manually edit these files using nano:

    bash

    Copy code

    nano /data/data/com.termux/files/usr/lib/python3.12/site-packages/shadowsocks/<file_name>.py

    Make the necessary changes and save the files.

  3. Check if there are other Python 3.10+ compatibility issues:

    If you continue to face issues, it might be helpful to check for other potential compatibility problems with Python 3.10 or higher. You could try using an earlier Python version (like 3.9) as an alternative if this doesn’t work.

Once you’ve updated all instances of MutableMapping, try running the Shadowsocks server again:

bash

Copy code

ssserver -c ~/shadowsocks/config.json

Let me know if you encounter further issues!

The issue you’re encountering with the MutableMapping in Python 3.10+ occurs because, in newer Python versions, MutableMapping has been moved to collections.abc. In the lru_cache.py file you showed, the import statement still references collections instead of collections.abc.

To fix this issue, you’ll need to modify the import statement in lru_cache.py:

1. Edit lru_cache.py to fix the MutableMapping import

Open the lru_cache.py file and change the import line for MutableMapping from:

python

Copy code

import collections

to:

python

Copy code

from collections.abc import MutableMapping

This ensures that the code uses the correct location for MutableMapping in Python 3.10+.

2. Save the file

After making this change, save the file and then try running the Shadowsocks server again.

3. Run the Shadowsocks Server

bash

Copy code

ssserver -c ~/shadowsocks/config.json

Let me know if you encounter any other issues after making this change!
