I am using ssh to start to open a connection to a "service" account on a remote server. The remote account is configured to automatically start a process which reads a few lines (three, right now), processes the information and returns a status. That part works.

On the client side I am testing with:

  use IPC:;Open2;

  my ($childin,$childout,$childerr);
  my $cmd = qq(/usr/bin/ssh -i $KEYFILE $USER\@$SERVER 2>/dev/null);

  my $pid = open2 ($childout,$childin,$cmd);
  my $status = $!;
  
  # check for success here
  
  # send commands
  print $childin $line1
  print $childin $line2
  print $childin $line3
  
  etc...

That works but if there is a "better" way I'd like to know. I tried with Net::SSH::Perl but couldn't get it to work with the remote server starting the command. Maybe I am overlooking something.

The application is intended to allow a user to reset and change his or her Kerberos password from a web interface. The web server does not run on the Authentication Server or KDC.
