LAB11.1 Step 9 "ssh-copy-id ceph@storage1"

FreddieWilliams

I have followed all previous steps meticulously numerous times but after run command "ssh-copy-id ceph@storage1" It prompts me for a password.  Thoughts?

[ceph@rdo-cc ~]$
[ceph@rdo-cc ~]$ ssh-copy-id ceph@storage1
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
ceph@storage1's password:

I am stuck at the same issue regarding the password credentials for the storage nodes. Does anyone know the password or a way around this issue?

serewicz,

When starting the Lab at 11.1 all configurations that is needed for this particular lab should be preconfigured correct? Or do I have to start at a previous lab and work my way back up to this lab to authenticate to the ceph storage nodes?

Hi everyone.

I have been trying to run the the commande to cpy the public key to the storage nodes as per the instruction. And followed the instruction to the letter up to this point of the instruction in Lab 11.1. Which means that i have not set any password for the ceph user on the nodes, i left it empty and pressed "ENTER".

I have tried to use the same password when i reached the step "ssh-copy-id ceph@storage1" BUT it did not work, i have used "ceph" as the password and also did not work, so i am stuck at this step as all steps in the labs build on each other.

It has been a challenge to understand the labs. the luck of explanation of the command we are supposed to execute, is a major setback in this course, i think each step should be explained and put into context, ie why the steps is necessary, which services are affected and why, is there any other way to complete the tasks etc..

I am saying this because i have already completed course 152 on edx and i know how complex openstack ecosystem is, and reducing this complexity into very basic steps without elaboration and puting every steps into its proper context is in my opinion a setback for this course. 

The other setback is the instability of the lms in generate and the lab environment in particulare. I have taken a number of course on edx.or and i think runing the course on that plateform will emprove the stability of the course enormously. The lab environment can easely be integrated into the course on edx by usin LTI. and the forums can be created as part of the sections of the course itself.

I am not sure why this course is not on edx.org BUT i am certain it can be ported easely, as LFS152 is runing on edx.

I do hope that this feedback can be of some use to the designers of the course.

Mr. Serewicz,

Can you provide the root password to the storage nodes? these nodes were not configured by me prior to this lab. They are already provided. If I cannot authenticate via the steps provided it would be great to be able to access the ceph nodes so that I can finish my lab. This is a very important lab for me, especially after recieving a better understanding via your webcast today.

Mr. Serewicz,

Is it possible to receive the root password for the storage nodes. These nodes were not configured by me in any lab previous to Lab 11. And using the methods given in the LFS252 manual are not alloing me authenticate using ceph. This is an important lab for me and I would like to complete it, especially after your webcast today that gave me more insight on ceph. Thanks

I am able to access the storage nodes now by bypassing step 9. I will manually create the ceph user and continue.Great Webcast today, or evening my time!!

Hi serewicz.

I am a bit confused here. Do we need to execute "[ceph@rdo-cc ~]$ ssh-copy-id ceph@storage1"  as the ceph user or the root user.

Any help will be very much appreciated

Hi serewicz, thanks for all the help you are providing in this forum. i need help with the command step 5 lab11.1 

...

[ceph@rdo-cc ~]$ sudo \

> sed -i ’s/PasswordAuthentication\ no/PasswordAuthentication\ yes/’ /etc/ssh/sshd_config

sed: -e expression #1, char 1: unknown command: `â'

[ceph@rdo-cc ~]$  "

this is the output when i execute the command. i have repeated the command many times after restarting the lab environemt and got the same result.

appreciate your help
