rsuplnk

RSUPLNK(8)						     Linux Programmer's Manual							RSUPLNK(8)

NAME

       rsuplnk - User entry into the ROSE network.

SYNOPSIS

       rsuplnk [-q] <port>

DESCRIPTION

       The  rsuplnk  program  allows a user to gain entry into the ROSE network using the standard pseudo-digipeating method. Recent Linux kernels
       are aware of this form of operation and the ax25d program can listen for such connections. The normal mode of operation of a ROSE switch is
       to  have  one  ROSE address (ie port) per physical AX.25 port.  Therefore ROSE users coming in on a given AX.25 port will appear as if they
       come from the associated ROSE port. This is the reason for the need for a ROSE port as an argument.

       To use rsuplnk you need an entry in ax25d.conf to listen for incoming connections. In the example below, I will be listening for ROSE  con-
       nections on my AX.25 port 144 using the callsign KE4GAJ-10 and the ROSE port associated with the AX.25 port is rs144.

       #
       [KE4GAJ-10* VIA 144]
       NOCALL  * * * * * * L
       default * * * * * * - root /usr/sbin/rsuplnk rsuplnk rs144
       #

       There would typically be one rsuplnk per user access AX.25 port. The associated program for exiting a ROSE network is rsdwnlnk.

       All errors generated by rsuplnk are written to the system debug log file.

OPTIONS

       -q      Supresses the messages generated by rsuplnk when making the connection.

FILES

       /etc/ax25/rsports
