I have created the keys and placed the public key in the remote user directory (not the server root).
(remote machine: dwebapp1)
ex: /home/webarch/user_name/.ssh/authorized_keys2

cannot ssh into the remote machine using the following command:
ssh ${dwebapp1}

the manned description gives the following pattern:
[options] host [command]
(one of the options is this
Options:
-l user Log in using this user name.

But this is not working form me.
I just want to connect from one machine to the other without keying in the user name and password. Please help. The tutorial seems straight forward but I am having trouble. I am using the following tutorial link:

No Passwd Required - Mt Xia: Technical Consulting Group

Thank you for any help you can provide

Here is the error I am recieving when typing ssh ${dwebapp1} at the command line of the originating machine:

ssh: $\033[3~{dwebapp1}: no address associated with hostname.

Also,

I was not able to use 'scp' command. Instead I used a different ftp client to place the key file on the remote machine in the user's .ssh directory.

are you using openssh or ssh2?

I managed to ssh between servers. I created and installed public keys for both machines so that I can ssh from both servers to each other (from server A to B and from server B to A).

I did discover that if using the ssh command at the command line I don't need to use the ${servername} brackets, etc. simply typing 'ssh servername' is the correct format.

I am not sure why the difference from the tutorial I used but it works.

Also, I managed to use 'scp' command but I could only place the key in the root .ssh directory of the remote server.

I am not sure which version of ssh I am using since I am not the administrator of this box. How do I find out?

ssh -V
shows the Version
