beacon 命令

常用示例

说明

beacon is part of the ax25-tools suite for amateur packet radio on Linux. It periodically transmits a UI (Unnumbered Information) frame containing a user-supplied text message on a configured AX.25 port. Beacons announce a station's presence, advertise services, or publish APRS-style position and status data on packet networks. By default the destination address is IDENT and the message is sent every 30 minutes; both can be overridden. The program normally daemonises itself so it can keep running in the background while the operator continues other work. The -s and -m options turn it into a one-shot transmitter. The named _port_ must be a configured AX.25 interface (commonly a KISS TNC, a soundmodem, or a kernel AX.25 device) listed in /etc/ax25/axports.

参数

-c _src_call_

Configure the source callsign for the beacon. Defaults to the AX.25 callsign of the interface.

-d _dest_call_

Configure the destination callsign. Defaults to IDENT. Digipeaters may follow, separated by spaces, when the argument is quoted.

-f

Do not fork into the background; keep the process attached to the terminal.

-l

Enable logging of errors to the system log. Disabled by default.

-m

Send the message once with destination address set to MAIL instead of IDENT.

-s

Send the message text only once and exit.

-t _interval_

Time interval between transmissions, in minutes. Default is 30.

-v

Display version information.
