HEARD(5) File Formats Manual HEARD(5)

heardheard stations database

The heard file maps Ethernet addresses to call signs. The format is intended to be somewhat human readable to allow for debugging however this format should never be written or edited by a human. It is expected that this file will be maintained by iclcd(8).

Lines consist of the following fields:

Fields are seperated by a horizontal tab character (hex value 0x09) and lines are seperated by a newline character (hex value 0x0a).

Ethernet address
Ethernet addresses are expressed as six hexadecimal numbers separated by colons. The functions described in ether_aton(3) can read and produce this format.
Station callsign
The station callsign does not have a fixed format and is treated as an opaque ascii(7) string. It will only consist of printable characters and must contain at least one character, but no guarantees are made beyond this.
The station flags are expressed as a decimal number. The flags are described in hamdex(7).
First heard timestamp
The time that the station was first heard is expressed as a decimal number of seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
Last heard timestamp
The time that the station was last heard, expressed as above.
