- G8BPQ NODE COMMANDS
-
-
- This document explains the commands available within the Node section
- of the G8BPQ switch, and an explanation of the responses.
-
- First the result of inputting an invalid command:
-
- NOTTS:G8BPQ-2} Invalid command - Enter ? for command list
-
- Entering ? produces the following:
-
- NOTTS:G8BPQ-2} BBS CONNECT BYE INFO NODES PORTS ROUTES USERS
-
- Note that BBS is only present if the BBS support is enabled (BBS=1 in
- th config file). If you have defined your own applications, they will also
- be listed.
-
-
- The BBS (and your other application names) must be entered in full - all other
- commands can be abbreviated to the first character of the command.
-
-
- Entering BBS (or your own application name) will connect you to the first
- free BBS (etc) port, or give an error message if none are available.
-
-
- The CONNECT command is used to connect you to another node, or to a normal
- AX.25 user. To connect to another node, enter C NODECALL or C NODEALIAS.
- The system will select the 'best' radio port and neighbour to to use to
- reach the required node using its ROUTES and NODES lists.
-
- The format used to connect to another normal user depends on whether you
- have more than one radio port. The formats are:
-
- (stuff in [] being optional)
-
- C CALL [via digi1 [digi2...]] If you only have one port
-
-
- C P CALL [via digi1 [digi2...]] Where P is the port number,
- if you have more than 1.
-
-
- (You can use C 1 CALL if you only have 1 port - its just a waste of typing!)
-
-
- If you miss out the port number where it is needed, you will get an error
- message, listing the available ports.
-
- Normally you cannot override the automatic route selection when you connect
- to another node, but you can fool the system into thinking a node is a
- normal station by connecting to the alias, and adding an SSID. For example,
- if you want to connect to NOTTS:G8BPQ-2, you can force a Level 2 connect
- on a secified port by entering C P NOTTS-1
-
-
-
- The BYE commnad disconnects you from the switch.
-
-
-
- The INFO command sends your INFO text from the config file:
-
- NOTTS:G8BPQ-2} G8BPQ Packet Switch, Mapperley, Nottingham. IO92KX
- Commands are basically the same as NET/ROM, but to connect to another
- normal station (not another node), you must specify a port number before
- the callsign. Use PORTS command to list available ports. The BBS command
- connects you to the associated Mailbox.
-
-
-
- The PORTS command lists available ports. The descriptions come directly
- from the configuration file, and should give at least the frequency and
- baud rate used.
-
- NOTTS:G8BPQ-2} Ports:
- 1 144.650 MHz 1200 Baud (PC120)
- 2 432.675 MHz 1200 Baud (DRSI)
- 3 Experimental NET/ROM Link
-
-
-
- The NODES command lists all the other NETROM/THENET/BPQ Nodes known to
- your node:
-

-
-
- By entering N NODECALL (or N NODEALIAS), you can list the routes that
- the system will use to access that node:
-
- n rp2
-
- NOTTS:G8BPQ-2} Routes to: RP2:GB3RP-2
- 100 4 GB3RP-2
- 23 4 G0GDR-1
- 19 4 G0GDR-2
-
-
- The numbers displayed are the 'quality' - the relative desirability of
- using this route rather than another, and the Obsolesance Count, an
- indication of how long it is since the system was last told about (
- or successfully used) this route. The number starts at a value set in
- the config file (typically 5) and is decremented each time a 'NODES'
- broadcast is sent (typically evey hour).
-
-
-
-
- The ROUTES command lists the stations which this node can hear.
-
- NOTTS:G8BPQ-2} Routes:
- 2 G4RFG-1 0 0!
- 1 G4RFG 0 0!
- 1 GB7LX-2 0 0!
- 2 GB7LX-7 20 0!
- 2 G0GDR-1 120 62!
- 1 G0GDR-2 100 49!
- 2 G7AXC-7 50 41!
- 1 GB3RP-2 100 17!
- 1 G1EUP-8 50 0!
- 1 GB7LED 50 1!
- 1 G4XMH-1 50 0!
- 2 GB7LRG-7 10 0
-
- The first number is the port. The second is the quality. This may be
- derived from the 'default quality' parameter in the PORTS section of the
- config file, or may be specified explicitly in the ROUTES section.
- A value of zero will prevent the route from being used, and is normally
- used when you have a one-way or marginal path. The third number is the
- number of NODES list entries which refer to this route. This isn't used
- by the software - it is just information for the user. The '!' indicates
- a 'locked route' - one entered in the CONFIG file. Other entries come and
- go as this node hears NODES broadcasts.
-
-
-
- The USERS command lists the stations currently using the node.
-
-
- NOTTS:G8BPQ-2} G8BPQ Network System V3.21 (95)
- Host6(NOTTS:G8BPQ-2)
- Host3(NOTTS:G8BPQ-2) <--> Circuit(LRG7:G0GDR-1 G8BPQ-1)
- Uplink(G9XXX) <~~> Downlink(G9YYY)
-
-
- Host is an internal (Normally BBS Port)
- Circuit is a link from/to another node.
- Uplink is a connection from a normal Ax.25 station.
- Downlink is a connection to a normal user.
-
- The <--> indicates an active session. <~~> indicates a session being set up.
-
- The Number on the end of the header line is the number of free buffers.
-
-
-
- There are a few commands not given in the menu. These are primarily of
- interest to the sysop, (or for me to experiment with). They are LINKS,
- STATS, L4T1, and PACLEN.
-
-
- The LINKS command lists the currently active AX.25 Sessions (Both user
- access and node-node links)
-
- NOTTS:G8BPQ-2} Links:
- G0GDR-1 G8BPQ-2 S=5 P=2 T=3 V=2
-
- S is the link state (see AX25 protocol spec, but the main ones are
- 2 (connecting) 4 (disconnecting) 5 (connected)).
- P is the port.
- T is the link type. 1=Uplink, 2=Downlink, 3=Node-Node link.
- V is the AX.25 Version (1 or 2).
-
-
-
-
- The STATS command displays a number of counters.
-
- NOTTS:G8BPQ-2}
- Time active (mins) 77
- Timer Overruns 1
- Buffer pool empty 0
- Minimum free buffs 73
- Current free buffs 95
- L4 Frames Sent 11
- L4 Frames Received 31
- L4 Frames Resent 0
- L4 Connects Sent 4
- L4 Connects RXed 0
- L3 Frames Relayed 0
- L2 Frames Digi-ed 0 0 0
- L2 Frames Heard 2082 3539 0
- L2 Frames Received 36 53 0
- L2 Frames Sent 72 72 15
- L2 Timeouts 14 4 0
- TX Underruns 0 0 0
- RX Overruns 0 0 0
- FRMRs Sent 0 0 0
- FRMRs Received 0 0 0
- Frames abandoned 0 1 0
- Link Active % 0 73 2 26 0 00
-
- Most are fairly obvious, but a few need a bit of explanation. There is one
- set of level 2 counters for each port.
-
-
- Time Active is the time since the system was loaded.
-
- Timer Overruns count the number of times the main code (which is initiated
- by the timer interrupt) is still running when the next timer interrupt
- occured. If it increments very rapidly (several times a minute), it
- indicates that the PC is too slow for the amount of data being processed.
- It is normal for an XT class machine running a couple of BBS ports to get
- about one overrun per minute. My 10MHz AT clone very rarely shows any.
-
- RX Overruns indicate characters lost because the software didn't process
- the interrupts fast enough. If you are running KISS ports, and you get
- a lot (ie a significant percentage of L2 frames heard), try reducing the
- speed of the link from the PC to the TNC. If you are using an HDLC card
- (DRSI or PC120), particularly at high speed, then there isnt much you
- can do except buy a faster machine. (But I would like to hear from anyone
- having problems running at 9600 baud or above - I may be able to speed up
- the routines a bit).
-
- TX Underuns indicate a similar problem in responding to TX interrupts,
- but only apply to HDLC cards (you cant get a TX underrun on an async port).
-
- Frames abandoned counts the number of frames discarded because they have
- been waiting to be sent (for DCD to clear) for more than 60 secs. If a
- lot occur, then either your squelch is a bit dodgy, or the channel is
- VERY busy. Only used for HDLC cards.
-
- Link Active shows two values for each port. The first is the % of time
- in the last minute that your station was transmitting, and the second
- the % the channel was active (sum of Transmitting and DCD active). Only
- maintained for HDLC ports.
-
-
-
- The L4T1 command displays or sets the Level 4 timeout used for the current
- session. It is primarily for me to experiment with.
-
-
- PACLEN sets or displays the PACLEN value used for messages generated by
- the node (eg command responses). Again it is mainly for me to play with.
