6 node - Node front end for AX.25, NET/ROM, Rose and TCP
7
9 node [-c]
10
12 Node is a simple node front end, modelled after the node shells of
13 TheNet and G8BPQ nodes.
14
16 -c Enable compression. With this option it is assumed that
17 the incoming call is using Zlib based compression (modi‐
18 fied Lempel-Ziv 1977). Currently no negotiation is done
19 so the caller must be aware of this. You probably want to
20 set up a separate AX.25, NET/ROM or ROSE callsign in
21 ax25d.conf or a separate TCP port in inetd.conf to listen
22 to compressed connects.
23 At the moment I know only two implementations compatible
25 with this compression method, namely LinuxNode and
26 Clussed.

29 The following commands are supported for users of node:
30 ? Give short list of available commands.
32 Bye Disconnect user from the node.
34 Connect <port> <call> [via <call1> ...] [d|s] For AX.25
36 Connect <call | alias> [d|s] For NET/ROM
38 Connect <call> <address> [<digi>] [d|s] For ROSE
40 Initiate an AX.25, NET/ROM or ROSE connection to a remote
42 host. If only one argument is supplied then the connec‐
43 tion is assumed to be a NET/ROM connection and the argu‐
44 ment specifies the callsign of alias of a NET/ROM node.
45 If more than one argument is supplied and the second
46 parameter is composed of numeric characters only then the
47 connection is assumed to be a ROSE connection. Any other
48 combination is assumed to be an AX.25 connection with the
49 first argument being the AX25 port to use for the connec‐
50 tion.
51 For a ROSE connection the <address> part must be exactly
53 six or ten digits. If only six digits are supplied, the
54 DNIC (first four digits) default to the local DNIC. The
55 local DNIC is assumed to be that of the first configured
56 Rose port in /etc/ax25/rsports.
57 The user may optionally supply as the last argument a
59 single character which modifies the default behaviour on
60 disconnection of the connection. If a single `s' is
61 entered as the last argument, then when the remote host
62 disconnects you will be returned to this node. If a sin‐
63 gle `d' is entered as the last argument, you will be dis‐
64 connected from this node too. The Default behaviour (nei‐
65 ther `s' nor `d' entered) is configured in the node con‐
66 figuration file and depends on the sysop preference.
67 Escape [<escape string>]
69 Override the sysop configured default escape character
70 setting. If the Escape command is given without an argu‐
71 ment then the current escape character setting is
72 returned to the user. The escape string may be specified
73 using any of the well known codings:
74 <char> to enter the escape character in its binary form.
76 ^C to enter the escape character as a control character
78 value.
79 NNN to set the escape character to a Decimal value.
81 0xNN to set the escape character to a HexaDecimal value.
83 0NNN to set the escape character to an Octal value.
85 off to disable the escape character.
87 Finger [<username>][@<hostname>]
89 Retrieve information about users of a system. If the user
90 name is omitted, shows the users currently logged on the
91 host. If the hostname is omitted, defaults to the local
92 host.
93 Help [<command>]
95 Give help for the specified command or this text if no
96 command is specified. Commands can not be abbreviated.
97 Use the "?" command to retrieve a list of available com‐
98 mands.
99 HOst <hostname> | <ip address>
101 Give the Domain Name Service host name information about
102 <hostname> or <ip address>.
103 Info Display the version information and the contents of the
105 /etc/ax25/node.info file, which should describe any
106 aspects of your system that you would like to brag about.
107 Links [* | <call>]
109 Give a list of active AX.25 connections to and from the
110 local host. With an optional argument * list also AX.25
111 sockets in state listening. A callsign as argument gives
112 a list of all connections with <call> as source or desti‐
113 nation address.
114 Mheard <portname>
116 Give a list of heard AX.25 stations on the specified
117 port.
118 NLinks Give a list of active NET/ROM connections to and from the
120 local host.
121 Nodes [* | <node>]
123 Show the NET/ROM node table of the local host. The nodes
124 on this list can be reached using the Connect command
125 without knowing the actual network path used (assuming
126 the network is OK).
127 The optional argument '*' toggles verbose mode, showing
129 the Obsolescence counter, relative path quality and the
130 port and neighbour node used to reach each node. You can
131 also specify a node callsign to get the verbose informa‐
132 tion for a single node. In that case a "which" field
133 that tells what route the kernel will use to reach the
134 node is also shown.
135 Ports Show the available AX.25 ports. Shown are the port name
137 and a short description for the port. The port name is
138 used when using the Connect command to connect to an user
139 or service not running NET/ROM (eg. not visible in the
140 Nodes list).
141 PIng <host> [<size>]
143 Check if a host can be reached trough the network by
144 sending an ICMP Echo Request packet to the host and wait‐
145 ing for it to reply. If a reply is received the round-
146 trip-time (RTT) between the local and remote hosts is
147 shown.
148 If an optional length is specified the data portion of
150 the packet is filled with length number of bytes.
151 Routes Show the NET/ROM neighbour table of the local host (ie.
153 the nodes which the local node directly talks with).
154 These nodes are used to reach the other nodes on the node
155 table.
156 Status Give some more or less useful information about the sys‐
158 tem.
159 Telnet <host> [<port>] [<string>] [d|s]
161 Initiate a telnet session to a remote host using TCP/IP.
162 By default, the telnet command connects to the TCP port
163 23 (allocated for telnet). You can specify another TCP
164 port or a TCP port name.
165 If an optional third argument <string> is given, that
167 string, followed by a CRLF is sent to the remote host
168 right after the connection is established. This is mainly
169 useful for command aliases.
170 If a single `s' is entered as the last parameter, then
172 when the remote host disconnects you will be returned to
173 this node. If a single `d' is entered as the last param‐
174 eter, you will be disconnected from this node too.
175 Default behaviour (neither `s' nor `d' entered) depends
176 on sysop configuration.
177 TAlk <user> <message>
179 Send a message to another user of the node. The user in
180 question must be in idle state (ie. not connected/con‐
181 necting anywhere or running a program).
182 If the user has an SSID other than zero, the SSID must be
184 specified. If multiple users are logged in with the same
185 callsign/SSID pair, those who are in idle state, get the
186 message.
187 Users Show a list of users currently connected to the local
189 node, where the users are coming from, and what are they
190 doing at the moment.
191 ZConnect Initiate a compressed AX.25, NET/ROM or ROSE connection.
193 The command arguments are the same as in Connect command.
194 Note that the other end must be expecting a compressed
195 connection (a LinuxNode started with the -c command line
196 option). No negotiation of compression is done.
197 ZTelnet Initiate a compressed telnet session. The command argu‐
199 ments are the same as in Telnet command. Note that the
200 other end must be expecting a compressed connection (a
201 LinuxNode started with the -c command line option). No
202 negotiation of compression is done.
