sftp question

Hello

I hope someone can help me with the following problem.




Background:  We are using SUN hosts running Solaris9.  For more than 
15 years we have had our users launch a Cshell script to create a tar 
file.   It also does ftp data transfer in the background for 
archiving on remote Macintosh computers.   The users just type the 
name of the script on the command line and then he/she enters a file 
name.  The process uses .netrc which contains the remote password. 
Permissions are set so that the users cannot read the contents of 
.netrc.
  So, the user does not know the password on the archiving host.  Of 
course ftp has huge security problems.  So, I am trying to create a 
similar process using sftp.  I have tried to do this using SUN's 
Solaris9 ssh-keygen, ssh-agent, ssh-add,  etc.  I have tried 
"passwordless" sftp setups I have found on websites.  This 
description is improper.  They don't require your normal password, 
but they do require a new "passphrase" (ie a new password).


My question:   Help?!   Can you tell me how to get Solaris9's version 
of sftp/ssh to work in such a fashion as I described above.   That 
is, sftp launched with a Cshell script and have the 
password/passphrase entered in the background perhaps by another 
shell script, which is called by the first one.


Regards.
