in thread Need help in doing SFTP via command line

Hello, Thanks for the suggestion. Yes I was able to instal Net::SFTP::Foreign and I was able to successfully connect to the server.
The place where I am stuck is when I try to do a 'Put'. I get the following message 
put failed: the authenticity of the target host can't be established, 
+the remote host public key is probably not present on the '~/.ssh/kno
+wn_hosts' file

The reason being that there seems to be an offending key in the ssh/known_hosts file , which has to be overidden.
I tried to do the same thing from the command line and I got the following result. From the command line , I can select the option "yes" for it to continue connecting to the server , but I do not know if I can do the same thing from the STP::Foreign module
Here is my command line output 

 sftp 2000550000506913@sftp.XXX.com@upload-itms6.XXX.com

Warning: the ECDSA host key for 'upload-itms6.XXX.com' differs from th
+e key for the IP address '152.125.77.44'
Offending key for IP in /Users/punitpawar/.ssh/known_hosts:2
Matching host key in /Users/punitpawar/.ssh/known_hosts:7

Are you sure you want to continue connecting (yes/no)? yes
2000550000506913@sftp.XXX.com@upload-itms6.XXX.com's password:

    You can remove it with ssh-keygen.

      It seems that I cannot connect to the SFTP server in the first place I get the following error: 
      Connecting to SFTP Server 
unable to connect to remote host: the authenticity of the target host 
+can't be established, the remote host public key is probably not pres
+ent on the '~/.ssh/known_hosts' file

      As suggested I tried using ssh-keyagent to get rid of the conflicting keys but that did not help 
      
## doing a ssh-keygen

print "\n Disabling StrictHostKeyChecking \n";

my %opts =(password => $password);

 my  $ssh = Net::OpenSSH->new($hostName, %opts,
           master_opts => [-o => "StrictHostKeyChecking=no"]
           );


## Connecting to SFTP server
print "\n Connecting to SFTP Server \n";

my $sftp = Net::SFTP::Foreign->new(host => $url,
                                    user => $userName,
                                  password => $password
    );
$sftp->die_on_error("unable to connect to remote host");

      Any help on this will really be appreciated. I am stuck and not sure what to do...

        ok I got this to work by doing the following thing and by not using openSSH module 
        
## Connecting to SFTP server
print "\n Connecting to SFTP Server \n";

my $sftp = Net::SFTP::Foreign->new(host => $url,
                                    user => $userName,
                                  password => $password,
                                  more => [-o => 'StrictHostKeyCheckin
+g no']
    );
$sftp->die_on_error("unable to connect to remote host");

    If you search the documentation for known_hosts, you find there several approaches on how to deal with this situation.
