Allows p2p connections only to/from specified nodes #688

Closed splix closed 5 years ago

splix commented 5 years ago

New command line option to specify file with approved remotes. The file should contain one potential node per line, as a full address or just ID. If full address is specified, the IP:PORT should be verified with the connection, in addition to node ID.

Example:

cat nodes.txt
enode://908db53d90ed1d157a7b543e9b6ceec63dbe00fcaad5cabc22dedb1892bc26533cd6005d6e4316723a3d48bdbcee46066b7029c4fc6dbb8f64f8b16cc920073f@10.10.0.16:30303

geth --allow-peers nodes.txt

This should allow connection only to/from bootnodes and 3 nodes from that file
