NAME

       node.conf - LinuxNode configuration file.

DESCRIPTION

       Node.conf  file  is read by LinuxNode at program startup and is used to
       modify the behaviour of the node.

       The lines within node.conf must either be a comment line, which  starts
       with  a  #  in  the  first column, or one of the commands listed below.
       Commands and arguments are delimited  by  white  space.  Arguments  can
       contain  white space if they are enclosed in single or double quotes. C
       style character literals are not parsed and  parameter  expansion  (see
       below) is not done inside single quotes.

       Available configuration commands are:

       Alias <NAme> β€β€™<command> [<args...>]β€β€™
                     Sets   up  a  command  alias.  The  number  of  uppercase
                     characters at the beginning of <NAme> specifies how  much
                     the  user  may abbreviate the command. The uppercase part
                     should be long enough to separate the command from  other
                     commands  starting with the same letters. If there are no
                     uppercase letters in the beginning,  the  whole  name  is
                     converted  to  upper case and user can not abbreviate the
                     command.  Note   that   certain   %-escapes   (positional
                     parameters,  current time) have a reasonable meaning only
                     when the alias is actually executed and thus they  should
                     not be parsed at the time the configuration file is read.
                     This  can  be  achieved  by  enclosing  the  command  and
                     argument part in single quotes. Another possibility is to
                     use double quotes and escape  the  percent  sign  with  a
                     backslash (eg. \%1)

       ConnTimeout <timeout>
                     When  user is connected to another system via this system
                     and the connection is idle (no  data  flowing  in  either
                     direction)   for  <timeout>  seconds  the  connection  is
                     dropped and user disconnected from node.  Default is 3600
                     seconds (1 hour).

       EscapeChar <escape string>
                     Specifies the escape character.  The escape string may be
                     specified using any of the well known codings:

                     <char> to enter the escape character in its binary  form.

                     ^C  to  enter the escape character as a control character
                     value.

                     NNN to set the escape character to a Decimal value.

                     0xNN to set the escape character to a HexaDecimal  value.

                     0NNN to set the escape character to an Octal value.

                     off to disable the escape character.

                     The default is CTRL-T (^T).

                     Note  that the escape mechanism breaks 8-bit transparency
                     of LinuxNode and you should either disable it or set  the
                     no-escape  flag in node.perms for the forwarding stations
                     if (compressed) forward is run trough LinuxNode. Also the
                     Escape  user  command  can be used in a forward script to
                     disable the escape (see node(8)).

       ExtCmd <NAme> <flags> <uid> <exec> <args...>
                     Sets up an external command.

                     NAme      This  is  the  name  under  which  the  command
                               appears  at  nodes command list.  The number of
                               uppercase characters at the beginning of <NAme>
                               specifies  how much the user may abbreviate the
                               command.  The uppercase  part  should  be  long
                               enough  to  separate  the  command  from  other
                               commands starting with  the  same  letters.  If
                               there   are   no   uppercase   letters  in  the
                               beginning, the whole name is converted to upper
                               case and user can not abbreviate the command.

                     flags     This is a sum of flags that control the way the
                               external command  is  executed.  Currently  two
                               flags are implemented:

                               1    Run  command  through  pipe.  Without this
                                    flag node just  fork()s  and  exec()s  the
                                    specified command and then waits for it to
                                    terminate. The command  must  it  self  be
                                    aware  about  the  underlying protocol. It
                                    must handle packetising  and  any  end  of
                                    line  conversions.  With this flag however
                                    node sets up a pipe between  it  self  and
                                    the  command  and  handles packetising and
                                    end of line conversions for it.

                               2    Reconnected to flag. If this flag is  set,
                                    the  user  gets  a  reconnected  to prompt
                                    after the external command is finished.

                     uid       This is the userid that the  following  command
                               should run under when executing.

                     exec      This is the executable that should be executed.

                     args...   These  are  the  optional  arguments  that  are
                               passed  to  the executable.  The first argument
                               is the command  name  that  is  passed  to  the
                               program (argv[0]). It is usually the executable
                               name without path.  See the Alias command for a
                               discussion  about  the  command  arguments  and
                               %-escapes (parameter expansion).

       HiddenPorts <portname> ...
                     Marks the AX.25 port <portname> as hidden.  Hidden  ports
                     are not shown to users in Links, Mheard, Ports and Routes
                     commands and can not  be  used  to  make  AX.25  downlink
                     connections  unless  user is specially permitted to do so
                     (see  node.perms(5)).  Up  to  32  hidden  ports  can  be
                     specified with this command.

       HostName <hostname>
                     This  is  the  visible  hostname  of the node. It will be
                     shown at telnet login and in the node welcome message.

       IdleTimeout <timeout>
                     After <timeout> seconds of inactivity while waiting for a
                     command  user  is  disconnected from node. Default is 900
                     seconds (15 mins).

       LocalNet <network>
                     Defines a "local" network. Users telneting from hosts  in
                     this  network are treated separately (see node.perms(5)).
                     <network> is a KA9Q NOS style network address  consisting
                     of  a  dotted-quad IP address of the network and a number
                     of significant bits  separated  by  a  slash.  Note  that
                     127.0.0.0/8  (loopback net) is also considered "local" by
                     default.

       LogLevel <loglevel>
                     Specifies what node should log. The available levels are:

                     0    Don’t log anything.

                     1    Log only critical errors.

                     2    Log errors and logins/logouts.

                     3    Log errors, logins/logouts and all gateway commands.

                     Default is to log only critical errors.

       NodeId <id>   This is the id that is shown in every message from  node.
                     Default is "LinuxNode}".

       NodePrompt <prompt>
                     Sets  the  prompt  string. The prompt string is evaluated
                     every time it is printed  so  what  was  previously  said
                     about %-escapes (parameter expansion) in Alias command is
                     valid here also.

       NrPort <portname>
                     This is the name of the netrom port  that  is  used  when
                     making outgoing netrom connects. Normally it should match
                     the portname that is used in  ax25d.conf  to  listen  for
                     incoming  netrom calls. Default is the first netrom port.

       ReConnect on|off
                     ReConnect flag. If enabled, users gatewaying  to  another
                     host  get  reconnected to this node after the remote host
                     closes connection.  If it’s off connection  to  the  user
                     will  also  be  closed.  User  can  override  the default
                     behaviour with a single β€˜s’ or β€˜d’  at  the  end  of  the
                     gatewaying  command (connect or telnet).  Default is off.

       ResolveAddrs on|off
                     If enabled, dotted-quad  IP  addresses  are  resolved  to
                     symbolic  names  when pinging or telneting out. Also, the
                     domain name of the peer is resolved  for  telnet  logins.
                     Default is off.

CHARACTER LITERALS

       C  style  character  literals are parsed when reading the configuration
       file.  The following formats are expanded:

       \n            This is substituted with Line Feed

       \t            This is substituted with Horizontal Tab

       \v            This is substituted with Vertical Tab

       \b            This is substituted with Backspace

       \r            This is substituted with Carriage Return

       \f            This is substituted with Form Feed

       \a            This is substituted with Alert (BELL)

       \\            This is substituted with Backslash (\)

       \"            This is substituted with double quote (")

       \’            This is substituted with single quote (’)

       \xNN          This is substituted with the character  corresponding  to
                     the code value of NN interpreted as a hexadecimal number.

       \0NN          This is substituted with the character  corresponding  to
                     the code value of NN interpreted as an octal number.

       \0            This is substituted with the NUL character (ascii 0)

PARAMETER EXPANSION

       While  reading  the  configuration  file  a  word  starting with a % is
       expanded. The following formats are expanded:

       %parameter    This is substituted with the value of parameter

       %{parameter}  The same as above.

       %{parameter:default}
                     If parameter is defined  this  is  susbtituted  with  the
                     value  of  it.  If not, the default value is substituted.
                     This currently  applies  only  to  positional  parameters
                     0...9.

       The following parameters are defined:

       0...9   The   positional  parameters.  Positional  parameters  are  not
               meaningful while reading the node.conf so the default value (if
               present) is always substituted.

       F       The full hostname in upper case.

       f       The full hostname in lower case.

       H       The hostname in upper case.

       h       The hostname in lower case.

       I or i  Current time (HH:MM:SS).

       N or n  The node ID as set with the NodeId command.

       U       The  username  (callsign)  of  the remote station in upper case
               without the SSID.

       u       The username (callsign) of the remote  station  in  lower  case
               without the SSID.

       S       The  username  (callsign)  of  the remote station in upper case
               with the SSID.

       s       The username (callsign) of the remote  station  in  lower  case
               with the SSID.

       P       The  nodename  (callsign)  of the remote station (NET/ROM), the
               portname the user is coming in via (AX.25) or the ip address of
               the remote host (TCP).  In upper case without the SSID.

       p       The  nodename  (callsign)  of the remote station (NET/ROM), the
               portname the user is coming in via (AX.25) or the ip address of
               the remote host (TCP).  In lower case without the SSID.

       R       The  nodename  (callsign)  of the remote station (NET/ROM), the
               portname the user is coming in via (AX.25) or the ip address of
               the remote host (TCP).  In upper case with the SSID.

       r       The  nodename  (callsign)  of the remote station (NET/ROM), the
               portname the user is coming in via (AX.25) or the ip address of
               the remote host (TCP).  In lower case with the SSID.

       t       The  type  of  the  user  connection (ax25, netrom, rose, inet,
               host) in lower case.

       T       The type of the user  connection  (ax25,  netrom,  rose,  inet,
               host) in upper case.

       Anything else after a % is substituted with a %.
