USERGUIDE FOR TheNet X-1H
This brief note is intended for users of TheNet X-1H, and
explains the basic commands. Configuration and sysop features are
not covered fully.
TheNet X-1H is an extension of TheNet 1, and provides a number of
new features.
The switch provides the following user commands :
Connect
Info
Nodes
Routes
Users
Talk
CQ
BBS
Host
MHeard
Bye
DXcluster
IProute
ARP
QUIT
Not all commands may be available on every node as certain
commands might have been disabled. If a command has been enabled,
it will be displayed when you type an invalid command such as
'?'. In addition, there are some commands that are available but
are not displayed. The main ones of interest are :
Links
Mode
Parms
Stats
IPAddress
DXCAlias
BBSAlias
HostAlias
Connect
If the connect command is given on its own, then assuming
that the sysop has set it up correctly, you will get
connected to the local BBS.
If you give another callsign, either of a local station or a
node, the node will attempt to connect you to that station
either by a level 4 connection or by downlinking. If you are
downlinking, you may also specify digipeaters.
In either case, you get either a connected message or a
message telling you of the failure to connect. If you enter
any other command at this stage, the connection attempt will
be aborted.
Info
This command gives information about the node as a
combination of a message stored in the EPROM and a message
entered by the Sysop.
Nodes
This command gives information about the distant nodes that
this node thinks it can get to. With no parameter, it shows
the alias and callsign of all the nodes except those staring
with a '#' character. If a parameter of '*' is given, those
'hidden' nodes will also be shown.
If a callsign or alias is given that the node does not know,
it gives an error message. If the callsign or alias of a
known node is given, the node gives details of the routes it
knows about that lead to that destination. The display shows
one option per line, each of which consists of the path
quality, obsolescence count and port followed by the
callsign of the neighbour. If any route is in use, a chevron
is shown against the appropriate entry.
Routes
This command gives information about the neighbouring nodes
that can be heard. For each neighbour, the display shows the
port number, the callsign, the path quality and the number
of nodes accessible through this neighbour. If a route has
been 'locked' by the sysop, then a '!' character is shown
after an entry. The sysop may have configured the node to
display nodes as callsign or as alias:callsign.
Users
This shows who is using the node. It does not show other
nodes that are using the node as a level 3 relay, nor does
it show those users who have connected to the node but
otherwise have done nothing.
The display shows the through connections, followed by those
users who are connected to the switch and 'idle'. It also
shows those users who are connected to the conferencing
facility. The latter stations are shown connected to a
destination called 'Talk', whilst in the case of
connections, the two endpoints are shown. For connections,
two symbols are used, '<-->' and '<..>'. The former is used
for established connections whilst the latter is used for
connections being established.
Talk
The Talk command allows a group of users to hold a
conference call. It also allows a user to send a message to
another user of the node provided that user is connected to
the switch but is not patched through to another station and
is not currently tyring to connect to another station.
A user enters the conference by giving the command 'talk'.
He/she gets a message informing them of this and reminding
them that the command to escape from the talk command is
'/exit'. Any other users currently in the conference get a
message from the node telling them of the callsign of the
user who has joined them. At this point, every line sent by
a user in the conference is copied to all other users in the
conference, preceded by their callsign.
To exit from the conference, the command '/exit' is used.
This causes a response message to be sent to the user, and
at the same time all of those left in the conference get a
message from the node telling them of the station who has
left the conference. If you force a disconnect, the other
stations are not told of your departure.
A string of text may be entered on the same line as the talk
command when the command is given. If this is done, before
the user is connected to the conference, that string of text
is sent to all the other users of the node who appear in the
'user' list but are not connected to anything else. For
example if GxABC were to type :
TALK GyXYZ, Hello fred can I have a chat - type TALK
then other users of the node ( including presumably Fred,
would get the message :
GxABC>> GyXYZ. Hello fred can I have a chat - type TALK
on their screens. The only exception to this is that sysops
are not sent the message.
CQ
This command is used to broadcast a CQ message. In addition,
the fact that you are calling CQ is indicated in the USER
list. The callsign will be your own with a different SSID,
and anyone else can connect to you by connecting to the
callsign with the appropriate SSID.
The CQ remains 'primed' for a while, and if any other
command is given to the node the CQ will be cancelled.
BBS
When you issue the BBS command, assuming that the sysop has
configured it, you will be connected to the local BBS.
If you enter the command 'BBS ?', then the current setting
of the BBS will be displayed.
Host
The HOST command operates just like the BBS command. It may
have been disabled by the sysop, it may have been set to
connect to the same station as the BBS, or it may have been
set to connect to another host system.
If you enter the command 'HOST ?', then the current setting
of the HOST will be displayed.
MHeard
If enabled, the heard list shows the last few stations
heard. The number of entries is limited and set by the sysop
so any stations not heard for a while may get pushed out of
the list by others heard. Assuming that a station is not
pushed out in this manner, the display shows the number of
packets heard from that station since it appeared in the
list and the time since it was last heard. The time is
hours, minutes and seconds. The list also shows the port on
which the station was heard ( port 0 is the radio port ),
and if it hears IP frames or Net/Rom frames, it adds a note
to show that the station is a node and/or a TCP/IP station.
If the list is long enough so that a station is not heard
for 12 hours, it will get deleted anyway.
Links
The LINKS command shows the level 2 connections to the node.
This is usually of academic interest, but I use it in
testing. The display shows the links, one per line, with the
two callsigns, the link state, the port number and the
current number of retries.
Mode
The MODE command is a bit like the PARMS command. It shows a
number of additional parameters. These are as follows as
shown by example :
MODE
THENET:G8KBB-5> 0 1800 6 3 2 20 0 600 2 900 1 31 0 1
with the following meanings :
0 Host mode protocol ( 0 = standard, 1 = DCD mode )
1800 CWID period. Delay in seconds between CWID
6 CWID speed 10's of msec per dot. 6 equals 20 wpm
3 Enable / disable nodes broadcasts mask.
2 RS232 protocol, 0 = crosslink, 1,2 or 3 are KISS
20 TxDelay in 10's of milliseconds ( Centiseconds ?? )
0 Full duplex control. 0 equals simplex
600 RS232 port nodes broadcast interval in seconds
2 Nodes broadcast algorithm port mask
900 Beacon period in seconds
1 'connect' redirector. 0 is to HOST, 1 is to BBS
31 Each bit controls one of the 'user' help messages
0 This byte controls the broadcasting of 'hash' nodes
1 This byte enables / disables the extra alias operation
If you want additional details, ask the sysop for a copy of
the overview guide.
Parms
This shows the node parameters as per TheNet 1.01 ( I am not
going to list them again here. Sorry ).
Bye and Quit
These commands disconnects you from the node, closing the
link. It says goodbye before disconnecting you if it has
been so configured by the sysop. Quit does just the same as
Bye does.
DXcluster
If there is a local DXcluster, this command may have been
configured by the sysop to connect you to it. It therefore
operates in a manner very similar to the BBS command.
Stats
The stats command gives lots of data about the node
operation. A full description of the information is
contained in the overview document.
IProute
This command is used by the sysop to configure the IP route
table. It may also be used to display the router table.
Arp
This command is similar to the IProute command, but shows
the Arp table. The Arp table provides a translation from Ip
address to callsign.
IPaddress
This command is used to set or display the current node IP
address.
BBSAlias
HostAlias
DXCAlias
These commands are used to set additional aliases for the
node. It can be configured by the sysop to accept connect
requests ( uplinks ) to the node callsign, the node alias,
or the 3 aliases shown by these commands. When the node
accepts a connection to one of these aliases, it will
immediately invoke the BBS, DXC or HOST commands for you.
The way this would normally be used is as follows. Suppose
your local ( for example ) BBS was not accessible on the
frequency that the node operates on. The BBS alias can be
configured to provide easy access across other nodes to the
BBS. Hence in the case of the Ipswich nodes, GB7MXM does not
have a port on 144.650, but the node IPS2 on 144.650 can get
to it by means of another node and a 9600 baud link. If IPS2
is set to accept the extra aliases, and if BBSAlias is set
to MXMBBS, then anyone who tries to uplink to MXMBBS in the
Ipswich area would be automatically connected to GB7MXM. It
goes without saying that if GB7MXM had a port on 144.650
itself, then chaos would ensue.
