[Dxspider-support] Node pairs that never connect

Thu Dec 26 12:24:33 GMT 2024

No problem Luigi.
Better to know, we never know who is really trying to connect to us,
especially if the connection was not defined with ‘password’. 
In my case, DO5SSB is trying to connect to one of the nodes I manage,
replacing DB0SUE, and he doesn't succeed, if he hadn't set a password, he or
anyone else would be connected. And I think that's a danger when you don't
know who your neighbour really is.
And for those who are not dxspider and can't set a password, you filter by
IP, and that's it.

Hi Kin,

You're right: as you told me, I've remembered that the link is actually
locked down because IQ8DO-6 is running a very old Spider's release (v
1.57 build 451).
I'm very sorry for my previous mail Kin, my apologies.

I've sent a mail to IQ8DO-6's sysop asking to update his Spider or remove
form his crontab the entry related to my node. We will see what happens.

Thank you for your effort, Kin!

Merry Christmas and Happy New Year!
