Either point to the right private key or else upload the right public key.

I think i have done it already

[however]Just before leaving work, i checked that the id_key.pub (from id_rsa, created on the client, box B, home desktop) was correct and it was.

Line 4 of? What file are you referring to? what other key could it possibly point to (i only have one private key on the client,home box B)

It would be in ~/.ssh/config on the machine you are connecting from.

However, with 90 posts, I've lost track.

Just to review, you seem to be able to get to the various machines so now it is "just" a matter of sorting the keys to the right destinations:

You'll need two key pairs on A, one for B and one for C. The public components go to the respective target machines. The ~/.ssh/config file on A can have shortcuts for connecting to B and C.

I thought that making one key-pair on A, could be used for B and C (I will have to figure out why it works this way on my own but, nevertheless i agree with you:

I feel the same way. This is taking too long and I also need a break to see things more clearly.
I will mark this thread as SOLVED as I managed to connect at least 2 boxes (out of three) to each other. Now, as you mentioned it's a matter to pause and get the right key in the right place.
Thank you for the invaluable fast networking lessons
