Getting closer to connecting without a passphrase - thanks, Michael Hirsh. I still failed, though. However, here is the output that you requested, along with the commands that I tried to run to get this process to work. Now when I ssh in, it prompts me "Enter passphrase for key '/home/user/.ssh/id_dsa':"

COMMANDS THAT I USED TO TRY TO GET SSH TO WORK WITHOUT A PASSPHRASE
rm -rf ~/.ssh   //to start .ssh from scratch
ssh-keygen -t rsa1  //to generate type1 public and private keys
cp ~/.ssh/identity.pub ~/.ssh/authorized_keys  //to make type 1 file to upload to server
cp ~/.ssh/id_dsa.pub ~/.ssh/authorized_keys2   //to make type 2 key file to upload to server
ftp ~/.ssh/authorized_keys AND  ~/.ssh/authorized_keys2 to remote machine's ~/.ssh //upload files
ssh user at shell1.host.com //test .ssh to see if it works
eval `ssh-agent`  //do a ssh-agent on server?
exit  //thinking I should exit to run next command locally
eval `ssh-agent` //run ssh-agent locally
ssh-add ~/.ssh/identity
ssh user at shell1.host.com //testing to see if I connect passphraseLESS
eval `ssh-agent` //failed to connect without passphrase, decided to run eval on remote machine

FAILED TO CONNECT WITHOUT USING A PASSPHRASE.


GENERATING TYPE 1 KEY
[user at change user]$ ssh-keygen -t rsa1
Generating public/private rsa1 key pair.
Enter file in which to save the key (/home/user/.ssh/identity): /home/user/.ssh/identity
Created directory '/home/user/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/user/.ssh/identity.
Your public key has been saved in /home/user/.ssh/identity.pub.
The key fingerprint is:
b0:15:bd:79:c4:bd:3e:99:1b:d5:87:1e:56:62:c4:6c user at change

GENERATING TYPE 2 KEY
[user at change user]$ ssh-keygen -t dsa 
Generating public/private dsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_dsa): /home/user/.ssh/id_dsa
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Passphrases do not match.  Try again.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/user/.ssh/id_dsa.
Your public key has been saved in /home/user/.ssh/id_dsa.pub.
The key fingerprint is:

[user at change user]$ 

SSH'ING TO SERVER FOR FIRST TIME
[user at change user]$ ssh rk4com at shell1.host.com
The authenticity of host 'shell1.host.com (209.211.232.3)' can't be established.
RSA key fingerprint is 8f:fc:f4:70:9d:ec:7d:0e:bb:e3:8f:1f:c9:c9:55:92.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'shell1.host.com,209.211.232.3' (RSA) to the list of known hosts.
