Cluster Network  AR-Cluster Sysop Manual

Network commands allows the connecting, monitoring and configuration of your node and other nodes operating in the network. 


General Network Commands


The INIT command sends initialization sequence with another local node. 


init k5ab      


The RINIT command simulates an initialization request from another node and starts the resulting outbound initialization protocol.  


rinit k5ab      


The MERGE command is used to update your local DX and WWV database tables from another node.  Optional numbers can be included in the command to specify the number of DX and WWV spots to merge.  If the number is not included the command defaults to 10 DX and 5 WWV spots.

The PING command is used to test communications paths with other nodes in the cluster network.  The roundtrip time of the ping is displayed.  If the round-trip time is less than one second, the time is shown in milliseconds.  The /Route option can be used to display the traced route of the ping.  The /Route option can only be used on AR-Cluster nodes and will not be sent to attached DOS nodes.  The /Quiet option can be used to ping a remote node without reporting the results.

The PING/DISCONNECT command can be used to disconnect a station if he does not return your ping.  This command can be added into the scheduler to automatically remove a node with no active connection. The command only executes with nodes directly connected to you.  If the ping has not been returned by the time the next PING/D starts, the station will automatically be disconnected.  A good way to start is to send the PING/D CALL command from the command line.  Type in a PING/D K1XX and another PING/D K1XX before the first one is returned and you will see a disconnect of K1XX.  Reconnect to K1XX and start another PING/D K1XX and wait for the return of the ping and then send another   PING/D K1XX and no disconnect should occur.  Now add the PING/D K1XX to the scheduler and set it to go off every 10 minutes or shorter if needed.


The SET/EXTERNAL command is used to place a node into the –EXT, (external) protocol.  The –EXT protocol removes the reporting of network node and user reports.  The –EXT protocol is used to isolate geographical regions.  Its also used during contests to reduce traffic down some of the crowded RF systems.

The SET/NODE command is used to place a callsign on the nodes list.  Callsigns in the node list get the PCxx/Arxx protocol while callsigns not in the nodes list connect as users.


set/node k5mdx       

set/nonode k5mdx     



Tracing Network Spots


AR-Cluster has advanced protocol for tracking questionable spots across the network.  Spots for DX, Announcement, TALK, WWV, and WX can be traced back to their source.   The command is started from the main menu by Sysop>TraceSpot>SpotType>DblClickOnSpot.  This action will generate special protocol which will walk the network back to the source of the spot.  The route of the spot will then be displayed to the sysop along with the user or node that generated the spot.  If a user is telneting into a node, his Internet address will also be displayed.  This capability has been very successful in tracking interference to the cluster network.


Network Commands


Network commands allow a sysop to control clusters participating in a network.  When a network command is received on the node, its interpreted into local commands.  More that one local command can be executed off a network command.  Network commands get sent out to all ARC nodes in the network, so prefix the command with a descriptor identifying your local region. 


The Cfg>Network-Commands option sets up the network command and local commands which get executed.  The CTDXCC, Central Texas DX and Contest Club, nodes might set up a command named CTDXCC_CONTEST_MODE which might execute local commands of SET/MODE CONTEST and ANN/LOCAL Entering Contest Mode.


Now any ARC sysop in the network could issue the network command SET/NETWORK CTDXCC_CONTEST_MODE which would  switch all participating nodes into the contest mode and make a local announce on each local node that the node is entering the contest mode.

Remote Sysop Commands

The RCMD (remote commands), can be used to execute commands on other nodes connected on the network.  Almost all AR-Cluster commands are remotable.   Remote command privileges are enabled by checking the Remote-sysop box in the Cfg>User(Local)>Call>Switches dialog.
