Configuration for networking code.

Fields§

§listen_addr: SocketAddr

The address on which this node should listen for connections.

Can be address:port or just address. If there is no configured port, Zebra will use the default port for the configured network.

address can be an IP address or a DNS name. DNS names are only resolved once, when Zebra starts up.

If a specific listener address is configured, Zebra will advertise it to other nodes. But by default, Zebra uses an unspecified address (“0.0.0.0” or “[::]”), which is not advertised to other nodes.

Zebra does not currently support:

However, other Zebra instances compensate for unspecified or incorrect listener addresses by adding the external IP addresses of peers to their address books.

§network: Network

The network to connect to.

§initial_mainnet_peers: IndexSet<String>

A list of initial peers for the peerset when operating on mainnet.

§initial_testnet_peers: IndexSet<String>

A list of initial peers for the peerset when operating on testnet.

§cache_dir: CacheDir

An optional root directory for storing cached peer address data.

§Configuration

Set to:

  • true to read and write peer addresses to disk using the default cache path,
  • false to disable reading and writing peer addresses to disk,
  • '/custom/cache/directory' to read and write peer addresses to a custom directory.

By default, all Zebra instances run by the same user will share a single peer cache. If you use a custom cache path, you might also want to change state.cache_dir.

§Functionality

The peer cache is a list of the addresses of some recently useful peers.

For privacy reasons, the cache does not include any other information about peers, such as when they were connected to the node.

Deleting or modifying the peer cache can impact your node’s:

  • reliability: if DNS or the Zcash DNS seeders are unavailable or broken
  • security: if DNS is compromised with malicious peers

If you delete it, Zebra will replace it with a fresh set of peers from the DNS seeders.

§Defaults

The default directory is platform dependent, based on dirs::cache_dir():

PlatformValueExample
Linux$XDG_CACHE_HOME/zebra or $HOME/.cache/zebra/home/alice/.cache/zebra
macOS$HOME/Library/Caches/zebra/Users/Alice/Library/Caches/zebra
Windows{FOLDERID_LocalAppData}\zebraC:\Users\Alice\AppData\Local\zebra
Otherstd::env::current_dir()/cache/zebra/cache/zebra

§Security

If you are running Zebra with elevated permissions (“root”), create the directory for this file before running Zebra, and make sure the Zebra user account has exclusive access to that directory, and other users can’t modify its parent directories.

§Implementation Details

Each network has a separate peer list, which is updated regularly from the current address book. These lists are stored in network/mainnet.peers and network/testnet.peers files, underneath the cache_dir path.

Previous peer lists are automatically loaded at startup, and used to populate the initial peer set and address book.

§peerset_initial_target_size: usize

The initial target size for the peer set.

Also used to limit the number of inbound and outbound connections made by Zebra, and the size of the cached peer list.

If you have a slow network connection, and Zebra is having trouble syncing, try reducing the peer set size. You can also reduce the peer set size to reduce Zebra’s bandwidth usage.

§crawl_new_peer_interval: Duration

How frequently we attempt to crawl the network to discover new peer addresses.

Zebra asks its connected peers for more peer addresses:

  • regularly, every time crawl_new_peer_interval elapses, and
  • if the peer set is busy, and there aren’t any peer addresses for the next connection attempt.
§max_connections_per_ip: usize

The maximum number of peer connections Zebra will keep for a given IP address before it drops any additional peer connections with that IP.

The default and minimum value are 1.

§Security

Increasing this config above 1 reduces Zebra’s network security.

If this config is greater than 1, Zebra can initiate multiple outbound handshakes to the same IP address.

This config does not currently limit the number of inbound connections that Zebra will accept from the same IP address.

If Zebra makes multiple inbound or outbound connections to the same IP, they will be dropped after the handshake, but before adding them to the peer set. The total numbers of inbound and outbound connections are also limited to a multiple of peerset_initial_target_size.

Implementations§

source§

impl Config

source

pub fn peerset_outbound_connection_limit(&self) -> usize

The maximum number of outbound connections that Zebra will open at the same time. When this limit is reached, Zebra stops opening outbound connections.

§Security

See the note at INBOUND_PEER_LIMIT_MULTIPLIER.

§Performance

Zebra’s peer set should be limited to a reasonable size, to avoid queueing too many in-flight block downloads. A large queue of in-flight block downloads can choke a constrained local network connection.

We assume that Zebra nodes have at least 10 Mbps bandwidth. Therefore, a maximum-sized block can take up to 2 seconds to download. So the initial outbound peer set adds up to 100 seconds worth of blocks to the queue. If Zebra has reached its outbound peer limit, that adds an extra 200 seconds of queued blocks.

But the peer set for slow nodes is typically much smaller, due to the handshake RTT timeout. And Zebra responds to inbound request overloads by dropping peer connections.

source

pub fn peerset_inbound_connection_limit(&self) -> usize

The maximum number of inbound connections that Zebra will accept at the same time. When this limit is reached, Zebra drops new inbound connections, without handshaking on them.

§Security

See the note at INBOUND_PEER_LIMIT_MULTIPLIER.

source

pub fn peerset_total_connection_limit(&self) -> usize

The maximum number of inbound and outbound connections that Zebra will have at the same time.

source

pub fn initial_peer_hostnames(&self) -> &IndexSet<String>

Returns the initial seed peer hostnames for the configured network.

source

pub async fn initial_peers(&self) -> HashSet<PeerSocketAddr>

Resolve initial seed peer IP addresses, based on the configured network, and load cached peers from disk, if available.

§Panics

If a configured address is an invalid SocketAddr or DNS name.

source

async fn resolve_peers(peers: &HashSet<String>) -> HashSet<PeerSocketAddr>

Concurrently resolves peers into zero or more IP addresses, with a timeout of a few seconds on each DNS request.

If DNS resolution fails or times out for all peers, continues retrying until at least one peer is found.

source

async fn resolve_host(host: &str, max_retries: usize) -> HashSet<PeerSocketAddr>

Resolves host into zero or more IP addresses, retrying up to max_retries times.

If DNS continues to fail, returns an empty list of addresses.

§Panics

If a configured address is an invalid SocketAddr or DNS name.

source

async fn resolve_host_once( host: &str ) -> Result<HashSet<PeerSocketAddr>, BoxError>

Resolves host into zero or more IP addresses.

If host is a DNS name, performs DNS resolution with a timeout of a few seconds. If DNS resolution fails or times out, returns an error.

§Panics

If a configured address is an invalid SocketAddr or DNS name.

source

pub async fn load_peer_cache(&self) -> Result<HashSet<PeerSocketAddr>>

Returns the addresses in the peer list cache file, if available.

source

pub async fn update_peer_cache( &self, peer_list: HashSet<PeerSocketAddr> ) -> Result<()>

Atomically writes a new peer_list to the peer list cache file, if configured. If the list is empty, keeps the previous cache file.

Also creates the peer cache directory, if it doesn’t already exist.

Atomic writes avoid corrupting the cache if Zebra panics or crashes, or if multiple Zebra instances try to read and write the same cache file.
