# Timeouts

Every timeout is set beside what it bounds. Each layer bounds its own handshake,
and nothing adds an overall limit, so a stack's handshakes may together take the
sum of their timeouts.

## Handshakes

| What | Key | Default |
| --- | --- | --- |
| TCP connect, name resolution included | [`tcp`](../transport/tcp.md#dial_timeout) `dial_timeout` | `10s` |

| TLS | [`tls`](../transport/tls.md#handshake_timeout) `handshake_timeout` | `10s` |
| WebSocket | [`ws`](../transport/ws.md#handshake_timeout) `handshake_timeout` | `10s` |

| Mixed's first byte | [`mixed`](../inbound/mixed.md#first_byte_timeout) `first_byte_timeout` | `10s` |
| Sniffing | [`sniff`](../routing/sniffing.md#timeout) `timeout` | `300ms` |
