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.
