Utility to generate the seeds.txt list that is compiled into the client (see src/chainparamsseeds.h and other utilities in contrib/seeds).
Be sure to update PATTERN_AGENT in makeseeds.py to include the current version,
and remove old versions as necessary (at a minimum when GetDesireableServiceFlags
changes its default return value, as those are the services which seeds are added
to addrman with).
The seeds compiled into the release are created from the dnsseed.dump output file of a
Bitcoin ABC Seeder that has been running for at least 30 days. The scripts
below assume that the dnsseed.dump file from the mainnet seeder has been copied to
seeds_main.txt and the dnsseed.dump file from the testnet seeder has been copied to
seeds_test.txt.
python3 makeseeds.py < seeds_main.txt > nodes_main.txt
python3 makeseeds.py < seeds_test.txt > nodes_test.txt
python3 generate-seeds.py . > ../../src/chainparamsseeds.h
Ubuntu:
sudo apt-get install python3-dnspython
