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.
