- 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.
