Shell Programming and Scripting

Hi,

I am trying to avoid the passowrd prompt while sftp between two servers. I am trying to sftp from A to B and also from B to A.

I was successful in generating the keys and uploading the public key to server B. So A to B was successful.

But when i am trying to do the same from B to A, its not working. Its prompting for password.

This is what i did:

ssh-keygen -t dsa

scp .ssh/id_dsa.pub xyz@X.XXX.XXX.XX:/.ssh/authorized_keys

Now i log out and log in and try sftp to A from B, i am prompted for password...


Any suggestions?

Thanks in adv

There is a Perl module that handles this Net::SFTP. All modern *NIX distros come with Perl. You may have to install the modules. I'm not sure if you have root permissions. After installing the needed modules, this task could be done in about 4 lines of code.

#!/usr/bin/perl
use Net::SFTP;
my %args = ("user", "USERNAME", "password", "PASSWORD");
my $sftp = Net::SFTP->new($host, %args);
$sftp->get("REMOTE_FILENAME", "LOCAL_FILENAME");

Hi

I am trying to make a shell script to automate the ftp process. The FTP command works fine but the script is not able to enter the username and password automatically. It stops at the username prompt and I have to do things manually from there on. Any solution??

One more thing - is there any command which would do the work of the RETURN KEY? Like if i want to skip the user name prompt by pressing the return key...can this action be coded in a shell script by a command?

Thanks

Hi

as i observed further, the script execution stops as soon as it enters the ftp mode. no command executes after the ftp command. however if i use 'bye' to exit the ftp mode, the rest of the commands in the shell script execute automatically. So do we have to write a separate shell script for ftp mode? is it possible? a shell script to execute just in the ftp modE?
Please helpppp

Best client utility around for FTP scripting operations is lftp (LFTP - sophisticated file transfer program ), it handles many flavors of FTP including SFTP and has username/password mgmt.
