I've decided to try tacking my never-ending problems in remote kernel access to a RPi from my Windows desktop. I seem to have painted myself into a corner such that Arnoud's instructions here return nothing when I try to use WolframSSH from the command line. This despite the fact that I can use ssh (MobaXterm) to perform the same command. Anyone have any debugging ideas?

<path>java -jar WolframSSH.jar user@pi ls returns nothing. no user@hostname and command gives me the prompts to add them and then returns nothing. I'm using both v9 and v10 versions of WolframSSH, since the latter is known to be buggy.

@hhh it is working as designed. Do you have documentation in your MMA release?

@hhh or

Following up on my problems above, I am finally able to get this answer to work if I manually create a link name for LinkCreate, which continues to choose a private IP for the name. If I establish a remote kernel in this fashion, is it possible to connect a notebook to the remote kernel or am I stuck with sending commands through LinkWrite?

@ybeltukov I was pretty busy during the weekend, couldn't get to igraph. Would you be willing to help me make a Linux binary that works for more people? What I need is just testing really. If yes, please email me.

Hmmh... are numbers in form of x + y^(1/2) unique (no other values of x and y could be found for the number) if x and y are positive rational numbers and square ro root of y is not rational?

Hmh. Simple Reduce tells they're unique presentations. Next: how to efficiently calculate values of x and y from such a number?

Reduce[x + Sqrt[y] == 1 + Sqrt[2] && x > 0 && y > 0 && Sqrt[y] \[NotElement] Rationals, {x, y}, Rationals] (* False *)

Eh, pls explain...

Oh well. In above case, I can actually use ToNumberField to extract x and y.
