Announcing N2YGK's Linux aprsdigi-2.4.4. March, 2004
Release 2.4.4 of N2YGK's advanced APRS digipeater is now available for
free under the terms of the GNU Public License (GPL) at
This release has the following new features:
- Aprsdigi is now a sourceforge.net project. Please visit aprsdigi.sf.net
and sign up to be a developer or join the users or developers mailing lists.
- Short (-s) command line options replaced with long ones (--long). Short
options are now deprecated and may disappear in a future release.
- Ability to specify a list of ports that get sent a verbatim duplicate copy
of all packets received on a given port. Useful for "reflecting" what's
heard on an RF port to a local LAN for instance. This is different from
APRS-IS (e.g. aprsd) since the data is sent with UDP (multicast or unicast).
Use with caution (or not at all) on RF ports.
Added in 2.4.3:
- UDP/IP (v4 and v6) unicast and multicast (ASM) support. Useful for
connecting aprsdigi's over the Internet, WLANs, etc.
(Note: this is *not* TCP support as used by APRS-IS, aprsd, etc.)
Both transparent and "3rd party" tunneling are supported.
- Budlist to permit/deny digipeating of traffic for individuals or groups of
AX.25 and IP sources. IP budlists are helpful when using IP multicast!
- Interfaces may be set to transmit- or receive-only.
- Interfaces may be set to disable retransmission of received packets on
the same interface (one-armed routing).
- Unix FIFO supported as an interface type. Mostly useful for debugging.
- Bug fixed that caused aprsdigi to crash upon TRACEn-n callsign insertion
when the digipeater list was full.
Along with these features:
- Digipeater callsign substitution (e.g. RELAY replaced w/N0CLU-12).
- WIDE, WIDEn-n, TRACE, and TRACEn-n.
- As many radio interfaces as you can plug into your Linux machine
with flexible gatewaying between them.
- Special handling for Mic-Encoder, Kenwood TH-D7, and TheNet X1J4, including
- Suppression of duplicate and looping packets.
- Works with Linux 2.4 kernel AX.25 network stack. This means any AX.25
interface supported by the kernel will work, not just a TNC2 clone.
Examples include all the BAYCOM interfaces (BAYPAC, PICPAR, PICSER, etc.),
soundcards, 8530 SCC cards, any serial port KISS TNC, etc.
