NAME

       kissattach, spattach - Attach a KISS or 6PACK interface

SYNOPSIS

       kissattach [-b] [-6] [-l] [-m mtu] [-v] [-i inetaddr] tty port [inetaddr]

       spattach [-b] [-6] [-l] [-m mtu] [-v] [-i inetaddr] tty port [inetaddr]

DESCRIPTION

       Attach  a  KISS  or  a 6PACK interface to what is normally a tty line connected to a TNC in KISS or 6PACK
       mode. This program will turn itself into a background process. To  down  an  interface  send  its  attach
       process a SIGTERM.

       Kissattach  takes many of the parameters for the port from the axports(5) file. If the speed parameter in
       the file is not equal to zero then it is used for the serial port speed, a zero value means that no speed
       is set. The paclen parameter is used for the device mtu unless overridden by a value on the command line.

       The  tty  argument will typically be that of a serial port with a KISS or 6PACK TNC attached, although it
       could be a pseudo tty or a KISS port emulator such as an SCC card. Kissattach supports BSD-style  pseudo-
       terminals  as  well  as  the Unix98 pty's. If the tty argument is "/dev/ptmx", then Unix98 behaviour will
       automatically take effect. With Unix98 pty's, the slave  tty  name  could  not  be  forseen.  That's  why
       kissattach will print the corresponding slave pty name as a separate line on stdout.

       The port argument is the name of a port as given in the axports(5) file.

       The  optional  inetaddr  argument  is  the  IP  address  of the new interface. Some time it was mandatory
       argument (although due to historical reasons this restriction is lifted if the old -i  option  is  used).
       But there's really not a need for the interface to have an IP address assigned to.

OPTIONS

       -6              Use  the  6PACK  line  discipline  instead of KISS. This is the default if the program is
                       called as spattach so the option is a no-op for spattach.

       -i inetaddr     Set the internet address of the interface. This address may either be  a  dotted  decimal
                       address  or  a  host  name.  This option is now depreciated and the program will complain
                       about it, though still work.

       -l              Log messages to the system log, the default is not to.

       -b              Allow broadcasts on the interface (default no - because for e.g. samba broadcasts  are  a
                       pain..)

       -m mtu          Sets  the  mtu  of the interface. If this value is not given then the value is taken from
                       the paclen parameter in axports.

       -v              Display the version.
