You can set up keys in advance that will let you login noninteractively. Google 'passwordless ssh', scp uses the exact same daemon and login credentials as ssh and the internet is littered with examples.

hi,

i have tried with passwordless shh in google..

i followed the below steps ...

user:~> ssh-keygen -t rsa

Enter file in which to save the key (/home/cantin/.ssh/id_rsa):key.txt

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

till this step i did..


noe it is described in that site that:

ssh-keygen: password-less SSH login


The private key was saved in .ssh/id_rsa. This file is read-only and only for you. No one else must see the content of that file, as it is used to decrypt all correspondence encrypted with the public key.
The public key is save in .ssh/id_rsa.pub.
In this case, the content of file id_rsa.pub is ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEArkwv9X8eTVK4F7pMlSt45pWoiakFkZMwG9BjydOJPGH0RFNAy1QqIWBGWv7vS5K2tr+EEO+F 8WL2Y/jK4ZkUoQgoi+n7DWQVOHsRijcS3LvtO+50Np4yjXYWJKh29JL6GHcp8o7+YKEyVUMB2CSDOP99eF9g5Q0d+1U2WVdBWQM= cantin@sodium
It is one line in length.
Its content is then copied in file .ssh/authorized_keys of the system you wish to SSH to without being prompted for a password.



now i dont know which file to be copied in to remote machine...


please help me out???


thanks in advance,

You add the contents of the id_rsa.pub file, that was generated when you ran ssh-keygen, to the authorized_keys file in the $HOME/.ssh directory of the user you want to connect as, on the remote server.

i have followed all steps as you mentioned but am still not able to get the output..
