USER COMMAND LIST, PT II
****************************
PARMS (P) - (Parameters) Issuing this command will yield a status listing
of the node's parameters. There are 23 SYSOP settable parms in version 2.11
and the node response may look like this:
SKY:W7YB-3} 86 100 255 6 5 1800 6 7 10 1 0 30 3 0 1 100 32 240 2 3 180 4 4
Each parameter affects the node operation in one way or another. The
values chosen for one node will impact the operation of the other nodes in the
network. The convention is to number the parameters from left to right in the
example above, starting 1, 2, 3, etc. Users will not be able to change any of
the parms unless recognized as a SYSOP. However users may find various parm
values of interest, such as in finding path quality and timeliness of routes
between nodes.
ROUTES (R) - This command yields a listing of all radio line-of-sight or
wire-connected nodes "known" to the node, including those set by the SYSOP
routes locking commands. Due to AX.25 protocol variations, Thenet does
not automatically recognize KA-Nodes, ROSE, TEXNET, nor FLEXNET nodes in it's
ROUTES list. It will recognize G8BPQ, MSYS and TCP/IP nodes. A typical ROUTES
display may look like:
WTEX:W5CDM-3} Routes:
0 ODSA01:W5CDM-1 192 30
> 0 DKC:W2RRY-2 192 23
> 0 MAF:KE5PL-1 192 10
0 FST:N5DCZ-1 192 16
0 RKN:KE5PL-3 192 11
0 BGS:KE5PL-4 192 5
Shown in column 1, all of the connections are via direct radio port (0)
paths. The "right arrow" indicator tells us two of the paths are either in
use or have had activity within the past 15 minutes. All radio paths show a
standard path quality value of 192. The last column indicates the most active
node in the list is ODSA01 with 30 destination routes showing. The least
active is BGS with 5 destination routes.
It is possible for the NodeOp to lock a non-node alias or callsign into
the ROUTES list. This is done to indicate to the observer that a non-TheNet
node is available. An example might be a KA-node gateway:
MIST:KB7IVK-1} Routes:
> 0 AST:W7FBM-1 192 54
0 V1KING 192 0!
0 AST2:W7FBM-8 192 1
In this example V1KING is a KA-node gateway from the local LAN to 28.103.
The "0" in the number of destination routes column normally indicates a failed
path. An astute observer would have checked the INFO section and learned that
V1KING was a gateway. Also he would have noticed the V1KING entry in the
ROUTES response was a locked pseudo call-sign that should tip him off there
was something unusual about the entry. A connect from MIST to V1KING would
result in the user being connected to the KA-node.
USERS (U) - A command response might appear as follows:
AZ:N7OO-3} TheNet Plus 2.11st (713)
Uplink(AA5EK) <-L4-> Downlink(AA5EK K1MEA-7)
Circuit(N5KGP-1 N5MYI) <-L4-> Circuit(ONT:VE3KYZ-4 N5MYI)
Thrulink(BISBEE:WA7KYT-1) <-L3-> Thrulink(ONT:VE3KYZ-4)
Circuit(SVALAN:N7OO-4 K1SC)
Uplink(DF2AU) <..> CQ(DF2AU-15)
The first line identifies the node type and version. This information is
valuable to the experienced user since it provides insight into the commands
supported by the node. Command support is similar among the different node
types and their versions, but there are significant differences. The number in
parentheses indicates the free buffers (36 byte segments) currently available.
The amount of free buffers varies and is dependent upon the total destination
and neighbor nodes listed in the tables, as well as the number and activity of
it's users. Free buffers can be used as a "health indicator". Upon initial
startup, the value will be in the "720" range. Around the "450 - 500" area,
free buffer depletion may cause the node to respond with a "Node busy" to
command requests.
Version 2.10 introduces the <-L3->, <-L4-> symbols and the term "Thrulink"
to the USERS display. In the example above, the term "Uplink" refers to an
OSI level 2 connect from a local user to the network node. "Downlink" is
defined as an OSI level 4 network connect to a local user. A "Circuit" is
either an OSI level 4 network connect from a source node TO the local node, or
it may be a connect FROM the local node to a destination node. "Thrulink"
displays an OSI level 3 circuit from a source node to a destination node. As a
level 3 circuit, there may be more than one user traversing it bi-directionally
from end-to-end. User identity can be accomplished by connecting to either of
the nodes listed and performing a USERS command. Inactive level 3 circuits
will timeout after 5 minutes.
