Removes miner fees using nfqueue. Tested on ubuntu 16.04 mining on nanopool with claymore dual ethereum miner for linux version 9.4. re
It modifies outgoing packets using nfqueue, substituting the dev fee wallet address with your own wallet address.
Disable ufw
sudo ufw disable
Install python-nfqueue and python-scapy. Has been tested with python-nfqueue 0.5-1build2 and python-scapy 2.2.0-1 from the ubuntu 16.04 repositories, if using different versions you may need to modify the code as described here
sudo apt-get install python-nfqueue python-scapy
Download the program and run it as root (nfqueue needs to be run as root). Keep it running in the background
wget https://raw.githubusercontent.com/gkovacs/remove_miner_fees/master/remove_mining_fees.py
sudo python remove_miner_fees.py
Now you can start the miner
./ethdcrminer64 -epool eth-us-west1.nanopool.org:9999 -ewal 0xb70fc6f9865ce18c20d90ebf067d9951918f8933/someworker -epsw x -dpool stratum+tcp://siamining.com:7777 -dwal 74ab711929bfc28359c8485a4e488d2f89b623771788fbeca7e7f5fe993ec691fec713e9f35b.someworker -dcoin sia -dcri 70
Logging output, with modified packets, will be written to a file named remove_mining_fees_log.txt
Note that this program redirects mining fees to 0xb70fc6f9865ce18c20d90ebf067d9951918f8933 by default. You will want to substitute that with your own wallet address in the source code by editing the variable my_eth_address
Note that this program assumes port 9999 by default (used by nanopool). Substitute the port by editing the number after --dport 9999 in the iptables command.
If you are using a miner different than claymore ethereum, you will need to figure out what the dev fee addresses are for that miner so you can redirect them - you can do so by running tcpdump -i enp4s0 host eth-us-west1.nanopool.org -X > log_mining_activity.txt then looking through log_mining_activity.txt for strings that look like eth_submitLogin. Find the addresses, and add them to list addresses_to_redirect
