One point to update while creating ssh-keygen for 7th question.
before creating the ssh-keygen I tried check command for whether we have existing .pub

“ls -l ~/.ssh/id_*.pub”

when I tried to generate with out admin user it is generating below error

Thanks & Regards

@Govardhan, send a loom recording so that we can analyze it.

@tgp,

I can not upload the zoom recorded file and please find the below screen shot what commands I gave as input

ssh-keygen -t rsa
in the name filed as mykey
Enter passphrase as empty
2nd passphrase as empty

Hello @Govardhan
Please try again the steps in question 7 but when you enter the file in which you have to save the key enter the full path “/home/thor/.ssh/mykey” not “mykey” then you will not get permission denied error and you could proceed successfully to question 8 as your steps in it are right.

Govardhan · April 22, 2021, 3:51am

Thank you it is working after placing in particular path

Govardhan · April 22, 2021, 3:58am

@tgp /@Ayman

I can not proceed for the question 8 and please find the following below screen.

I entry the command the ssh-copy-id -i ~/.ssh/mykey.pub thor@app01
and ssh thor@app01
mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys, I’m trying to create the ~/.ssh directory as well as the authorized_keys file (command executed but not able find file in App01 server).
Use the chmod command to change the file permission:
chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys`

but it is not working . can any one please help

@tgp

can you please reply on the above issue. I apricate your help !

Ayman · April 23, 2021, 3:31pm

all you have to do is to only use this command ssh-copy-id -i ~/.ssh/mykey.pub thor@app01 to copy the content noting that this is the only requirement.
After executing this command you have to click on check and it will work fine then.

After entering the above command incase it asks for password please enter mjolnir123

kislay.sinha · August 20, 2021, 8:40pm

Please change the key permission with 755 of key files and it will work.
If it will ask for the password please use mjolnir123
It worked for me I was able to ssh thor@app01.
