The sage notebook does not show results

[Oscar Lazo]

Hello Sage people!

I am setting up a sage notebook server at my research institute to showcase software I have been writing in atomic physics. So I followed the instructions in

http://wiki.sagemath.org/SageServer

and now I can point the browser of a computer within the institute to the local static ip and I see the sage notebook as expected. The problem is that although I could create a new account, and notebooks, when I type in a cell say:

2+2

the notebook waits a little while and then shows no result. The corresponding message in the notebook terminal is

2015-09-01 14:20:37-0500 [HTTPChannel,13,127.0.0.1]
2015-09-01 14:20:37-0500 [HTTPChannel,13,127.0.0.1]
2015-09-01 14:20:49-0500 [HTTPChannel,8,127.0.0.1] got EOF subprocess must have crashed...
2015-09-01 14:20:49-0500 [HTTPChannel,8,127.0.0.1]
2015-09-01 14:20:49-0500 [HTTPChannel,8,127.0.0.1] Permission denied (publickey,password).

what is wrong?

Thank you very much!

I'm cc:ing to sage-notebook as well.  Sorry that I can't help but it does seem to be a permissions thing.  What happens if you start a new worksheet and then just try to save it, or to start a new worksheet, make a *text* cell change, and then save it?

That seems to work without a problem. I even wrote some rich text without problem. I saved and quit the worksheet and when I reopened it, the text was still there.

Okay, then it's almost certainly some kind of permissions thing (of what nature I dare not guess) with respect to computation, not sagenb per se, but rather wherever the computations are happening.

Point 6 says "I don't thing the following sudo syntax works anymore. I
had to do this by hand now." Did you do that?

What happened on point 7 of instructions? If it worked, have you tried it
with accounts sage1, sage2 and so on?

I would also, for a start, change

server_pool=['sage%d@localhost'%i for i in range(10)]

to just

server_pool=['sage0@localhost']

I wouldn't know how to do that, but it ran smoothly, asked me for a path to place the key, a passphrase and it all worked seemingly fine.

This did not work at all. It asked me for sage0's password, though I did not think it had one. I tried with oscarlazo's password which has root powers, but that didn't work either.

oscarlazo@VIDEO-AF:~$ sudo -u sageserver ssh sage0@localhost echo Done
sage0@localhost's password:
Permission denied, please try again.
sage0@localhost's password:
Permission denied, please try again.
sage0@localhost's password:
Permission denied (publickey,password).

 How could the sage0, sage1,... passwords be changed?

Thank you!
