Generate a clean DHT bootstrap node list.
|
|
Feeds on previously known nodes from standard input and a few well known
|
|
mainline DHT bootstrap nodes. Prints only nodes that appears to be active to a
|
|
quick nmap check. Make sure your internet connection is working well before
|
|
using this.
|

cat bdboot.txt | bdboot_generate.sh | tee /tmp/bdboot_generated.txt
|
|
cat /tmp/bdboot_generated.txt | sort -u > bdboot.txt
