[Dxspider-support] SECURITY MEASURES TO MINIMIZE ATTACKS

[Anthony (N2KI)]

Mikel,

Certainly.

You point out having bidirectional connections to your node partners.  As
an example,  If we were node partners, and you would connect to my node for
spot data,  why would I initiate a connection to your node from my end.
You are connecting to me.  So I do not understand the rationale of having
bidirectional connections other than it comes into play if the link is
broken somehow so as to reestablish the link.

The way I have my node set it to connect to my primary node partner.
Periodically, it checks to make sure the connection is established.  If it
is not, it will connect to my secondary node partner.  While connected to
the secondary partner, it periodically checks to see if primary is viable.
If it is, then it will connect to the primary again.  I also have a
tertiary in the event that the primary and secondary are non viable links.

This is my script for primary, secondary and tertiary node partners.
Perhaps there is a more efficient way, I don't know.  But it's what my node
has been doing.

0,30 * * * * start_connect('wb3ffv-2') unless (connected('wb3ffv-2') or
connected('g6nhu-2') or connected('wc2l'))
2,4,6,8,10,12,14,16,18,20,22,24,26,32,34,36,38,40,42,44,46,48,50,52,54,56 *
* * * start_connect('g6nhu-2') unless (connected('g6nhu-2') or
connected('wb3ffv-2') or connected('wc2l'))
15,33,47 * * * * start_connect('wc2l') unless (connected('wc2l') or
connected('g6nhu-2') or connected('wb3ffv-2'))
28,59 * * * * disconnect('g6nhu-2') if connected('g6nhu-2')
58,29 * * * * disconnect('wc2l') if connected('wc2l')










*Regards,Anthony *
