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).  Cur Äê
                     rently 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 net Äê
                     work 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 com Äê
                     mand 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 pro Äê
                     gram).

                     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 com Äê
                     pressed connection (a LinuxNode started with the  c command line option).  No negotiation of compression is done.
