Here is a Termux script in Bash that reduces ping by configuring the system's TCP congestion algorithm and optimizing the network settings:
```bash
#!/bin/bash
# Set the TCP congestion algorithm to cubic, which is suitable for most networks
echo "Setting TCP congestion algorithm to cubic..."
sysctl -w net.ipv4.tcp_congestion_control=cubic
# Enable TCP window scaling to improve performance
echo "Enabling TCP window scaling..."
sysctl -w net.ipv4.tcp_window_scaling=1
# Increase the TCP send buffer size to reduce packet loss
echo "Increasing TCP send buffer size..."
sysctl -w net.ipv4.tcp_wmem="4096 87380 174760"
# Increase the TCP receive buffer size to reduce packet loss
echo "Increasing TCP receive buffer size..."
sysctl -w net.ipv4.tcp_rmem="4096 87380 174760"
# Reduce the TCP initial congestion window to reduce packet loss
echo "Reducing TCP initial congestion window..."
sysctl -w net.ipv4.tcp_initial_window=10
# Apply the changes
echo "Applying changes..."
sysctl -p /etc/sysctl.conf
echo "Ping reduction settings applied successfully!"
```
Save this script as a file (e.g., `reduce_ping.sh`), make it executable with `chmod +x reduce_ping.sh`, and then run it with `./reduce_ping.sh`.
Note: This script requires the `sysctl` command, which is available in Termux. Also, please note that these settings may not work for all networks and may need to be adjusted based on your specific network configuration.
**Before running this script, make sure to test your ping speed using `ping -c 10 google.com` (or any other website) to get a baseline measurement. After running the script, test your ping speed again to see if there's any improvement.**
