NAME

       node - Node front end for AX.25, NET/ROM, Rose and TCP

SYNOPSIS

       node [-c]

DESCRIPTION

       Node  is  a  simple  node  front end, modelled after the node shells of
       TheNet and G8BPQ nodes.

OPTIONS

       -c            Enable compression. With this option it is  assumed  that
                     the   incoming  call  is  using  Zlib  based  compression
                     (modified Lempel-Ziv 1977).  Currently no negotiation  is
                     done  so  the  caller must be aware of this. You probably
                     want to set up a separate AX.25, NET/ROM or ROSE callsign
                     in  ax25d.conf  or  a  separate TCP port in inetd.conf to
                     listen to compressed connects.

                     At the moment I know only two implementations  compatible
                     with   this  compression  method,  namely  LinuxNode  and
                     Clussed.

NODE COMMANDS

       The following commands are supported for users of node:

       ?             Give short list of available commands.

       Bye           Disconnect user from the node.

       Connect <port> <call> [via <call1> ...] [d|s]  For AX.25

       Connect <call | alias> [d|s]                   For NET/ROM

       Connect <call> <address> [<digi>] [d|s]        For ROSE

                     Initiate an AX.25, NET/ROM or ROSE connection to a remote
                     host.    If  only  one  argument  is  supplied  then  the
                     connection is assumed to be a NET/ROM connection and  the
                     argument  specifies  the  callsign  of alias of a NET/ROM
                     node. If more than  one  argument  is  supplied  and  the
                     second  parameter  is composed of numeric characters only
                     then the connection is assumed to be a  ROSE  connection.
                     Any   other   combination  is  assumed  to  be  an  AX.25
                     connection with the first argument being the AX25 port to
                     use for the connection.

                     For  a ROSE connection the <address> part must be exactly
                     six or ten digits.  If only six digits are supplied,  the
                     DNIC  (first  four digits) default to the local DNIC. The
                     local DNIC is assumed to be that of the first  configured
                     Rose port in /etc/ax25/rsports.

                     The  user  may  optionally  supply as the last argument a
                     single character which modifies the default behaviour  on
                     disconnection  of  the  connection.   If  a single ‘s’ is
                     entered as the last argument, then when the  remote  host
                     disconnects  you  will  be  returned  to  this node. If a
                     single ‘d’ is entered as the last argument, you  will  be
                     disconnected  from  this  node too. The Default behaviour
                     (neither ‘s’ nor ‘d’ entered) is configured in  the  node
                     configuration file and depends on the sysop preference.

       Escape [<escape string>]
                     Override  the  sysop  configured default escape character
                     setting. If  the  Escape  command  is  given  without  an
                     argument  then  the  current  escape character setting is
                     returned to the user. 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.

       Finger [<username>][@<hostname>]
                     Retrieve information about users of a system. If the user
                     name  is omitted, shows the users currently logged on the
                     host. If the hostname is omitted, defaults to  the  local
                     host.

       Help [<command>]
                     Give  help  for  the specified command or this text if no
                     command is specified. Commands can  not  be  abbreviated.
                     Use  the  "?"  command  to  retrieve  a list of available
                     commands.

       HOst <hostname> | <ip address>
                     Give the Domain Name Service host name information  about
                     <hostname> or <ip address>.

       Info          Display  the  version information and the contents of the
                     /etc/ax25/node.info  file,  which  should  describe   any
                     aspects of your system that you would like to brag about.

       Links [* | <call>]
                     Give a list of active AX.25 connections to and  from  the
                     local  host.  With an optional argument * list also AX.25
                     sockets in state listening.  A callsign as argument gives
                     a  list  of  all  connections  with  <call>  as source or
                     destination address.

       Mheard <portname>
                     Give a list of heard  AX.25  stations  on  the  specified
                     port.

       NLinks        Give a list of active NET/ROM connections to and from the
                     local host.

       Nodes [* | <node>]
                     Show the NET/ROM node table of the local host. The  nodes
                     on  this  list  can  be reached using the Connect command
                     without knowing the actual network  path  used  (assuming
                     the network is OK).

                     The  optional  argument ’*’ toggles verbose mode, showing
                     the Obsolescence counter, relative path quality  and  the
                     port  and neighbour node used to reach each node. You can
                     also  specify  a  node  callsign  to  get   the   verbose
                     information  for  a  single node.  In that case a "which"
                     field that tells what route the kernel will use to  reach
                     the node is also shown.

       Ports         Show  the  available AX.25 ports. Shown are the port name
                     and a short description for the port. The  port  name  is
                     used when using the Connect command to connect to an user
                     or service not running NET/ROM (eg. not  visible  in  the
                     Nodes list).

       PIng <host> [<size>]
                     Check  if  a  host  can  be reached trough the network by
                     sending an ICMP Echo  Request  packet  to  the  host  and
                     waiting  for  it  to  reply.  If  a reply is received the
                     round-trip-time (RTT) between the local and remote  hosts
                     is shown.

                     If  an  optional  length is specified the data portion of
                     the packet is filled with length number of bytes.

       Routes        Show the NET/ROM neighbour table of the local  host  (ie.
                     the  nodes  which  the  local  node directly talks with).
                     These nodes are used to reach the other nodes on the node
                     table.

       Status        Give  some  more  or  less  useful  information about the
                     system.

       Telnet <host> [<port>] [<string>] [d|s]
                     Initiate a telnet session to a remote host using  TCP/IP.
                     By  default,  the telnet command connects to the TCP port
                     23 (allocated for telnet). You can  specify  another  TCP
                     port or a TCP port name.

                     If  an  optional  third  argument <string> is given, that
                     string, followed by a CRLF is sent  to  the  remote  host
                     right after the connection is established. This is mainly
                     useful for command aliases.

                     If a single ‘s’ is entered as the  last  parameter,  then
                     when  the remote host disconnects you will be returned to
                     this node.  If a  single  ‘d’  is  entered  as  the  last
                     parameter,  you  will be disconnected from this node too.
                     Default behaviour (neither ‘s’ nor ‘d’  entered)  depends
                     on sysop configuration.

       TAlk <user> <message>
                     Send  a  message to another user of the node. The user in
                     question   must   be   in    idle    state    (ie.    not
                     connected/connecting anywhere or running a program).

                     If the user has an SSID other than zero, the SSID must be
                     specified. If multiple users are logged in with the  same
                     callsign/SSID  pair, those who are in idle state, get the
                     message.

       Users         Show a list of users currently  connected  to  the  local
                     node,  where the users are coming from, and what are they
                     doing at the moment.

       ZConnect      Initiate a compressed AX.25, NET/ROM or ROSE  connection.
                     The command arguments are the same as in Connect command.
                     Note that the other end must be  expecting  a  compressed
                     connection  (a LinuxNode started with the -c command line
                     option).  No negotiation of compression is done.

       ZTelnet       Initiate  a  compressed  telnet  session.   The   command
                     arguments  are  the  same as in Telnet command. Note that
                     the other end must be expecting a  compressed  connection
                     (a  LinuxNode  started  with the -c command line option).
                     No negotiation of compression is done.
