Keeping a Connection open between 2 Nodes.

[calkob]

I have 2 node on the same network, one is 0.18.1 and the other is older 0.12.0.  I want to get 0.12 to stay connected to 0.18.1 permanently as its only connection for information whats the best way to go about that.

currently i can get them to connect simply by addnode in Conf but after a few minutes 0.18.1 is dropping the connection with 0.12.     also how do i stop from connecting to any other node.

I'm not confident with networking settings in bitcoin.conf but try to use these settings.

Connect to this node exclusively (use instead of addnode):

Code:

connect=(node IP)

Maybe it's disconnecting because the old version is misbehaving, try any of these:

Code:

whitelist=(IP)
bantime=5

Also, make sure that bitcoind isn't running in the background while editing your config file.

This sounds like XY problem, do you have any particular reason to stay use Bitcoin Core 0.12.0 which is outdated? If there aren't any, i suggest you to upgrade your Bitcoin Core.

AFAIK nc50lc suggestion should fix the problem, but if it's not, then try to share your debug.log file

Thanks for that working a treat now.

I think it is important that Bitcoin maintains its backward compatability and i want to see that older nodes can always stay connected to the network.
