KISSNETD(8) Linux System Managers Manual KISSNETD(8)NAME
kissnetd - Create a virtual network.
SYNOPSIS
kissnetd [-f size] [-v] [-p <num> | tty... ]
DESCRIPTION
Kissnetd allows the creation of a virtual network of AX.25 systems that use the KISS protocol. Each tty named on the command line is opened
and any KISS frames received on tty is copied to the other ttys. This allows a number of AX.25 systems to share the same packets.
OPTIONS -p num Automaticaly allocate num Unix98 slave pty's via /dev/ptmx. These are written to stdout and could be parsed by your startup
scripts. "kissnetd -p 3" is an comfortable alternative to "kissnetd /dev/ptmx /dev/ptmx /dev/ptmx".
-f size This sets the maximum KISS frame size that the program will handle. The default is 512 bytes which will be adequate under most
circumstances.
-v Enables verbose mode, tracing of data passed is sent to standard output.

mkiss - Attach a multi KISS interface
SYNOPSIS
mkiss [-c] [-f] [-h] [-l] [-s speed] [-p pollrate] [-v] [-x n_ptmx] ttyinterface pty ..
DESCRIPTION
Mkiss allows dual port TNCs or multiple TNCs sharing the same serial port to be used with the Linux AX.25 kernel software. The AX.25 soft-
ware has no support for dual port TNCs or multiple TNCs charing the same serial line. The different ports are addressed by encoding the
port number in the control byte of every kiss frame. Mkiss watches a serial port, and routes kiss frames to/from the pseudo ttys. The
other side of the pseudo ttys are then attached with kissattach as normal.
Statistics about the operation of mkiss may be obtained by sending the SIGUSR1 signal to the running program. On reception of such a signal
mkiss will print a set of statistics to the system log if logging has been enabled.
Although mention is made of using pseudo ttys as the last arguments, these devices may be normal serial ports. However mkiss provides no
way in which to set their speed, the speed must therefore be set by some other method.
If the pty argument is "/dev/ptmx", then Unix98 behaviour will automaticaly take effekt. With Unix98 pty's, the slave pty name could not be
forseen. That's why mkiss will print the corresponding slave pty name as a separate line on stdout.
If the pty name is the special name "none", no pty is opened. This is useful if you have multiport tnc like the KPC-9612 on i.e.
/dev/ttyUSB0 and you only like to handle packets for the second port. The KPC has no option to configure the second tnc to listen on kiss
port number 0. Thus, if you like to send all frames from the pty to the kiss port number 1, we need to tell mkiss to tag them for port num-
ber 1. This is done by "mkiss /dev/ttyUSB0 none /dev/ptmx". Frames received with port number 0 are discarded.
OPTIONS -c This enables a one-byte checksum on each incoming and outgoing KISS frame on the serial port. This checksum is used by G8BPQ KISS
roms to maintain the integrity of KISS frames.
-f This enables a 16-bit checksum on each incoming and outgoing KISS frame on the serial port. This checksum is used by Flexnet Node
and BayCom Mailbox to maintain the integrity of KISS frames.
-h Enables hardware handshaking on the serial line to the TNC. The KISS specification states that no hardware flow control shall be
used so the default is off. But some KISS implementations do use hardware flow control.
-l Enables system logging, the default is off.
-s speed Set the speed of the serial port.
-p pollrate
Enables polling. Polled mode is used by G8BPQ KISS roms to prevent contention on systems where multiple TNCs share the same
serial line. Pollrate is interval between polls (in 100ms units).
-v Display the version.
-x number This option is for Unix98 PTYs. It allocates "number" ptys; their names are written to stdout. When -x is used, the pty arguments
are optional. "mkiss -x 3 ttyname" is an comfortable alternative to "mkiss ttyname /dev/ptmx /dev/ptmx /dev/ptmx".
