Dear all,

i have been through

Quote:

sshpass : likewise
sshpass -p 't@uyM59bQ' ssh username@server.example.com

and lftp also

wanted to ask whether there is any direct,without installing any other library into the system.

Hi,

you should be using public key authentication instead of sshpass. From the sshpass sourceforge page:

Code:

Description
Sshpass is a tool for non-interactivly performing password authentication
with SSH's so called "interactive keyboard password authentication". Most
user should use SSH's more secure public key authentiaction instead.

A web search with the keywords "ssh-keygen public key authentication" should provide plenty of good tutorials for this.

You should also probably scp or rsync with ssh instead of sftp. We can provide a more specific answer if you can ask a more specific question.

The remote system will need sshd installed running.

I recommend the simple syntax of scp instead of sftp, and using keychain.

Keychain (installed from my distro's repository) saves my passphrase in memory. I'm promoted for the passphrase the first time I login after a boot and it remembers it (even across logout/login) until I reboot or kill the process.

That let's me do things like this, on the command line, in a script or even in a crontab script, without being prompted for anything. Assuming I have an account on example.com and have appended my public key to the ~/.ssh/autorized_keys file on it.

Code:

ssh example.com mkdir examples
scp ~/text/onefile.txt ~/text/other.txt example.com:examples
