how to do SSH if both instance having different "Key pair"- file name ?
Name does not matter as long as the key pair is the same
permission denied (publickey gssapi-keyex gssapi-with-mic) i tried everything but got this error
chmod 600
I am getting connection timeout error when I try to do the same.I did change the permission of the file as well ,but still getting the same error.Kindly suggest
It is facing issues to connect .. check IP, credentials, security group settings esp. port 22 should be open and the source security group (if different) should have access and check your key.
Hi Nihal
I also faced the same error.
Were you able to fix it?
If Yes, Can you please let me know what was the issue?
I'm unable to connect, I don't know why .. I followed your steps .. still not able to connect
Debug it … You might have missed something
Hello Namrata!
I did follow the steps and when I try to do ssh from my master with client private IP, it asks me for the password of the client and I don't remember it. Can you please help me with that?
I don't know your password.
well. it is working as normal user. But, it is refusing when i am trying as root user
error like "Please login as the user "ec2-user" rather than the user "root" "
Can you help me please ?
To login into ec2 you need to use ec2-user that is the default. You can switch to the root user after you have successfully logged in and need to perform activities of a root user.
@@NamrataHShah @NamrataHShah Thank you for your reply. I have copied the root pub key in the target node and enable public key access then it works. Actually l am setupin chef infra. So it's required direct root acces to deploy a cookbook. Now its fixed. Really I would like to apprentice your video. It was very useful in the beginnings.
btw, how for passcode less authentication between two amz ec2?
please explain.
Kindly elaborate more
@@NamrataHShah If i need passcode less ssh session between two ec2 (for ansible yaml to work) how i can proceed? please assist.
i just copied the pub key to the authorised key file and it worked.
I want to know if any more methods are there?
peace
hi there . When i do this it is asking me for the passphrase?????
If you create your key with passphrase then you will need to provide it. See if you create a key without the passphrase.
I got it the pem file was corrupted. I.e it was not copied properly
