# Manage Bor

The script is designed for the maintenance and management of peers in a Bor network, disconnecting peers that do not meet certain version criteria, and blocking traffic from the IPs associated with those peers.

```bash
import subprocess
import re
import json
import os

def remove_peer(enode):
    
    command = f'bor attach /var/lib/bor/bor.ipc --exec "admin.removePeer(\'{enode}\')"'
    
    try:
        
        subprocess.run(command, shell=True, check=True)
        print(f"Peer removed: {enode}")
    except subprocess.CalledProcessError as e:
        print(f"Error removing peer {enode}: {e}")

def block_ip(ip_address):
    
    block_command = f'sudo iptables -A INPUT -s {ip_address} -j DROP'
    os.system(block_command)
    print(f"Traffic from IP {ip_address} blocked using iptables")

get_peers_command = 'bor attach /var/lib/bor/bor.ipc --exec "admin.peers"'

def version_compare(v1, v2):
    """
    Compare version strings v1 and v2.
    Returns True if v1 is less than v2.
    """
    return v1 < v2

try:
    result = subprocess.check_output(get_peers_command, shell=True, text=True)
    result = re.sub(r'([{,]\s*)([A-Za-z_][a-zA-Z_0-9]*)(\s*:)','\\1"\\2"\\3', result)

    peers = json.loads(result)

    for peer in peers:
        caps = peer.get('caps', [])
        name_version = peer.get('name', '').split('/')[1] if '/' in peer.get('name', '') else ''
        ip_match = re.search(r'@(\d+\.\d+\.\d+\.\d+):30303', peer['enode'])

        if "snap/1" not in caps or version_compare(name_version, 'v1'):
            remove_peer(peer['enode'])

            if ip_match:
                ip_address = ip_match.group(1)
                block_ip(ip_address)
        else:
            print(f"Healthy peer: {peer['enode']}")

except subprocess.CalledProcessError as e:
    print(f"Error getting the list of peers: {e}")

```

Python and Requests Installation:

Make sure you have Python installed on your system. Open the terminal or command prompt. Execute the following command to install the `requests` library:

```bash
pip install requests
```

Script Execution:

Save the Python script (`Your_script.py`) in the directory of your choice.

Run the Script:

In the terminal or command prompt, navigate to the directory where the script is located. Execute the script using the following command:

```bash
python3 your_script.py
```

Results:

Iterates over the list of peers obtained from the Geth console. For each peer, it checks whether it has the "snap/1" capability and if the name version is less than "v1". If the above conditions are not met, it removes the peer using `admin.removePeer` and blocks the traffic from the associated IP using iptables.\
**Note:** You can use cron to automate the periodic execution of the script.
