Currently I'm executing the following command:

What option should I use?
Ssh Solutions
Solution 1 - Ssh
Use the -i option:
ssh -i mykey.pem user@mydomain.com
As noted in this answer, this file needs to have correct permissions set. The ssh man page says:
> ssh will simply ignore a private key file if it is accessible by others.
You can change the permissions with this command:
chmod go= mykey.pem
That is, set permissions for group and others equal to the empty list of permissions.
Solution 2 - Ssh
chmod 400 mykey.pem
ssh -i mykey.pem user@mydomain.com
Will connect you over ssh using a .pem file to any server.
Solution 3 - Ssh
For AWS if the user is ubuntu use the following to connect to remote server.
chmod 400 mykey.pem
ssh -i mykey.pem ubuntu@your-ip
Solution 4 - Ssh
To connect from Terminal to AWS AMI:
chmod 400 mykey.pem
ssh -i mykey.pem ec2-user@mydomain.com
Solution 5 - Ssh
You can connect to a AWS ec-2 instance using the following commands.
chmod 400 mykey.pem
ssh -i mykey.pem username@your-ip
by default the machine name usually be like ubuntu since usually ubuntu machine is used as a server so the following command will work in that case.
ssh -i mykey.pem ubuntu@your-ip
Solution 6 - Ssh
If you still got error messages like:
> Received disconnect from 34.219.50.0 port 22:2: Too many authentication failures. Disconnected from 34.219.50.0 port 22
- Edit your ssh config located at
~/.ssh/configand add new record at the end
Host mydomain.com
User ubuntu
IdentityFile /home/you/path-to-pem/key.pem
IdentitiesOnly yes
- Call short command:
ssh mydomain.com
Solution 7 - Ssh
what resolved it for me was to run: sudo chown $USER: {.pem_file}
