Hi Andrey! No, you are right, when I type "ssh localhost" on the command line (while being in the *sagecell* directory) I get the message* Permission denied (publickey).*
Let me explain my setup a bit better: - I am remotely connected to a Debian secured server (to connect to my server I use a pair of ssh keys, no password). - I installed both *sage *and *sagecell *on my secured server and I am for the moment trying to lauch the sagecell server from the command line on my secured server. - (Later on, the idea will be obviously to set everything up, so that I can connect to *sagecell *running on my server from an external laptop. But for now I wanted to test how things work while working the whole time wihtin my server.) - So technically, I thought I wouldn't need a second layer of ssh security to connect to *sagecell *for the moment, since I am launching it within my server. But did I understand your previous answer correctly, that this type of connection to *sagecell *without ssh is not possible, and that I need to configure another ssh connection via a pair of keys according to the step 3 from Installtion Guide (below)? I am not sure which identifiers for *username *and *host *should I then use? Still my username and my server name, just generating a second rsa key pair for the connection my server <> sagecell ? Sorry, I am a bit lost for the moment... :) Thank you very much for your advice! Varvara *--* *Edit config.py according to your needs. Of particular interest are host and username entries of the provider_info dictionary: you should be able to SSH to username@host without typing in a password. For example, by default, it assumes you can do ssh localhost without typing in a password. Unless you are running a private and firewalled server for youself, you’ll want to change this to a more restrictive account; otherwise anyone will be able to execute any code under your username. * *--* On Friday, 16 September 2022 at 21:48:30 UTC+2 [email protected] wrote: > Hi Varvara! > > Does "ssh localhost" work for you on the command line where you are trying > to start SageMathCell without entering anything (i.e. your password)?
