Can't ssh to AWS EC2: Identity file not access

问题:

I'm unable to ssh to my EC2 server and am getting the error:

ssh -i /Users/Skeniver/Keepass/skeniver.pem [e-mail]

Identity file /Users/Skeniver/Keepass/skeniver.pem not accessible: No such file or directory

The file is definitely in the directory and I've chmod'd the directory to 755 and the file to 600:

drwxr-xr-x  14 Skeniver  staff    476 28 Nov  2012 Keepass
-rw-------  1 Skeniver  staff    1696  5 Oct  2012 skeniverkey.pem

I'm pretty sure it's a permissions problem, but can't figure out why...

Here is the output of the ssh command using -v, in case it's of any use:

回答1:

You need the identity file to login to the box. Use the command:

ssh -i (identity_file) username@hostname"

This worked for me. Write just the filename (without any slashes), unlike Amazon EC2 tutorial which asks you to enter:

ssh -i /path/key_pair.pem ec2-user@public_dns_name

It worked for me after putting the identity file in the .ssh (hidden) folder on home. To view hidden folders on home, use ctrl+h

回答2:

I had similar issue and found that there was hidden char in command, pasting to plain text editor and copy back helped me.

回答3:

I was having this same issue. Storing the identity file in my ~/.ssh directory and running cd ~/.ssh before ssh -i (identity_file) username@hostname worked. I only ran into the issue when trying to run the ssh command from outside the ~/.ssh directory. Hopefully that helps

回答4:

I had the same problem and i found that the issue with the file path. Right click on the your key_pair.pem (identical file) go the properties and copy and now your comment is like

ssh -i /path/skeniver.pem user@your_public_ip

for example in my case command like

ssh -i /home/anil/.ssh/webKey.pem [e-mail]

回答6:

Try using

ssh -i Users/Skeniver/Keepass/skeniver.pem [e-mail]

instead of

ssh -i **/**Users/Skeniver/Keepass/skeniver.pem [e-mail]

回答7:

For your case just

just execute the following command to change permission

sudo chmod 400 /Users/Skeniver/Keepass/skeniver.pem

and then execute the command that will connect you to EC2

ssh -i /Users/Skeniver/Keepass/skeniver.pem [e-mail]
