scp file to another server without asking for password

Shell Programming and Scripting

hi

I tried reading some of the threads w.r.t scp/sftp file to another server in the same network without asking for password while copying files.....but couldnot succeed.

i have generated the public key for the system using "ssh-keygen -t " and kept it in the
.ssh/authorized_keys file.

even then it asked for password when i use scp

Any other way?

There might be some spaces while you tried to copy the public key to authorized_keys file.

hi

No additional spaces ...
some how its not working ...restarted the ssh as well

If you fix ssh connection without a password, the scp will work a well.
try this tutorial: http://www.ehow.com/how_4750765_rsync-over-ssh-password.html
and make sure your authorized_keys file has permissions of 600 when your done, or it wont work.

also - is the ssh server yours? sometime password less access is disabled in the sshd.conf.

Another good debugging option is to use "ssh -v into_the_server"

and you will see a lot of valuable info about the ssh process and where its failing.

hi

i followed the steps as mentioned in the article. but still its not successful
am getting error as:

It looks like you are using kerberos for authentication. Is there a line like

GSSAPIAuthentication yes

in your sshd configuration file?

7

no....

followed the instructions in the link

and added the following in the sshd_config file...
changed the value of "PermitEmptyPasswords no "
to
"PermitEmptyPasswords yes"
and restarted the ssh

GSSAPIAuthentication=no
GSSAPIKeyExchange=no
StrictHostKeyChecking no
GSSAPIAuthentication=no
GSSAPIKeyExchange=no

now am getting the error as

i have modified both the server files (sshd_config)
and both have public key of other servers in its authorized_keys2

Help me out!!!!
