[arm-allstar] Remote NODE

Luc,

 I had to go ahead and complete the command. So here it is as an attached
script. It will be in the next update but anyone that wants to try it out
go ahead.  Here is the syntax -

# Command Syntax

# remote-command.sh <node> <command> [port]
# Port defaults to 222

# Command Examples
# remote-command.sh 40000 *81   - Say time at node 40000
# remote-command.sh 40000 *340001   -  connect node 40000 to 40001
# remote-command.sh 40000 *76   - disconnect all nodes at 40000
# remote-command.sh 40000 *140001 223  - disconnect node 40001 from 40000 -
use  ssh port 223

The beauty of this command is that you do not need to be connected to any
of these nodes BUT you do need to have SSH permission. So it would be nodes
in your control.

The lookup searches both rpt_extnodes, dns-query (hamvoip) and local
routes. So it would work for local routes as long as the node and IP
address appeared in the [nodes] section of rpt.conf. In the future when we
start DNS'ing private nodes that will not be necessary.

Note you must create the password file and the passwords for all nodes you
connect to must be the same. You could use public keys also but you would
need to modify the ssh call.


*73 Doug*
