Status: This is a concise reference for the
v3dgsendutility. It complements the Datagram API and SAM v3 docs.
Overview
v3dgsend is a command-line helper for sending I2P datagrams using the SAM v3 interface. It is useful for testing datagram delivery, prototyping services, and verifying end-to-end behavior without writing a full client.
Typical uses include:
- Smoke-testing datagram reachability to a Destination
- Validating firewall and address book configuration
- Experimenting with raw vs. signed (repliable) datagrams
Usage
Basic invocation varies by platform and packaging. Common options include:
- Destination: base64 Destination or
.i2pname - Protocol: raw (PROTOCOL 18) or signed (PROTOCOL 17)
- Payload: inline string or file input
Refer to your distribution’s packaging or --help output for exact flags.
