Be sure to update
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 Cash Node 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 testnet3 seeder has been copied to
python3 makeseeds.py < seeds_main.txt > nodes_main.txt python3 makeseeds.py < seeds_testnet3.txt > nodes_testnet3.txt python3 makeseeds.py < seeds_testnet4.txt > nodes_testnet4.txt python3 makeseeds.py < seeds_scalenet.txt > nodes_scalenet.txt python3 generate-seeds.py . > ../../src/chainparamsseeds.h
sudo apt-get install python3-dnspython
Testing user agent pattern modifications
A sample 'dnsseed.dump.test' has been provided, which contains some patterns to test against. It should be adapted when changes are made.
To check that the emitted patterns match only those you want, you can run
the commands below.
You may need to temporarily disable ASN limiting, ensure that the uptime and
service bits in your test entries would pass the filters in
$ cp dnsseed.dump.test seeds_main.txt $ python3 makeseeds.py < seeds_main.txt | while read s; do grep -F "$s" seeds_main.txt ; done
