Why didnt you use ssh-keygen -t dsa?
would have produced something like:
Generating public/private dsa key pair.
Enter file in which to save the key (/home/vbe/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/vbe/.ssh/id_dsa.
Your public key has been saved in /home/vbe/.ssh/id_dsa.pub.
...
I have used the same command ssh-keygen -t dsa
It did ask me for a file name and .pub file was also generated.
Then I created a duplicate copy of the .pub file as authorized_keys and ftp to the remote machine.
Now it should not ask me for password when I try to ssh to the remote machine.....but it is asking for the password........
How do I achieve passwordless login.....is the above procedure correct ??
The mistake was to use ftp...
We assume sshd is running on both boxes, and so you should have transfered the file using scp, doing so you would have known if sshd is up on the remote server since it would have asked you the password...
Once transefred you could have tested again and it should have worked...
So start by checking if sshd is up on both servers then maybe check for incompatibilities (version differ too much?...)
There is a small correction in my reply above.....
The .pub file that was generated, I copied it into the remote system by means of ftp.
Then I logged off from ftp...and on system 1 i tried connecting to system2 by ssh.....
ftp was used only for copying authorized_keys file to remote machine.....
I tried using scp to copy the file but i am getting permission denied error inspite of changing all the file and directory permissions on both the systems to rw-r--r-- and rwzrw-rw- respectively....
