Is there a IP changer for Ubuntu 24?

I am trying to find some IP chagner to play on Ubuntu.
I've already started Tibia 8.6 on ubuntu and now I want to change ip so I can play on OTS.

I can not find anything that is working.
 
@QuickLearner I wrote a python script that does IP Change. I've used it only on 7.70 Client but should work also on the 8.6

Python: 
#!/usr/bin/env python3

# Read the binary file
import os
import sys

print(sys.argv)

if len(sys.argv) != 3:
    print("Usage: ./ip_changer <path_to_executable> <new_ip>")
    sys.exit(1)

server_list = [
    "tibia1.cipsoft.com",
    "tibia2.cipsoft.com",
    "server.tibia.com",
    "server2.tibia.com"
]

path_to_executable = sys.argv[1]
new_ip = sys.argv[2]

if not os.path.exists(path_to_executable):
    print("Tibia.exe not found")
    sys.exit(1)

for old_string in server_list:
    with open(path_to_executable, 'rb') as file:
        binary_data = file.read()

    # Calculate the padding length
    padding_length = len(old_string) - len(new_ip)
    padding = b"\x00" * padding_length

    # Perform the replacement
    binary_data = binary_data.replace(old_string.encode(), new_ip.encode() + padding)

    # Write the modified binary data back to the file
    with open(path_to_executable, 'wb') as file:
        file.write(binary_data)

I am afraid that to simply replace the server name at client file would not be enough, for client 8.6 you would also need to replace the RSA Key. I've got here a (very spaghetti) old C++ code which works for client 8.61. It wouldn't be hard to make it work for the 8.6 client, but because it uses a stupid strategy to locate the RSA Key, it will probably require the usage of a hex editor to find out the location of the RSA Key. I will let this code here anyway, it might be useful.
