java.lang.Objectnet.i2p.router.Blocklist
public class Blocklist
Manage blocking by IP address, in a manner similar to the Shitlist, which blocks by router hash. We also try to keep the two lists in sync: if a router at a given IP is blocked, we will also shitlist it "forever" (until the next reboot). While the reverse case (blocking the IP of a router shitlisted forever) is not automatic, the transports will call add() below to block the IP, which allows the transports to terminate an inbound connection before the router ident handshake. And the on-disk blocklist can also contain router hashes to be shitlisted. So, this class maintains three separate lists: 1) The list of IP ranges, read in from a file at startup 2) The list of hashes, read in from the same file 3) A list of single IPs, initially empty, added to as needed Read in the IP blocklist from a file, store it in-memory as efficiently as we can, and perform tests against it as requested. When queried for a peer that is blocklisted but isn't shitlisted, shitlist it forever, then go back to the file to get the original entry so we can add the reason to the shitlist text.

this tries to not return duplicates but I suppose it could. |

boolean |
isBlocklisted(Hash peer)
Does the peer's IP address appear in the blocklist? If so, and it isn't shitlisted, shitlist it forever... |

isBlocklisted(String ip)

static void |
main(String[] args)

void |
renderStatusHTML(Writer out)
write directly to the stream so we don't OOM on a huge list |
void |
shitlist(Hash peer)
We don't keep the comment field in-memory, so we have to go back out to the file to find it. |
