So my understanding of your question is that you want to have passwordless ssh command only work if its invoked by a particular script?
Really, the only reasonable way I can think to do that is:
1) push the passwordless ability to some other user
2) have that script be invoked via a sudo to that user and only that script.
That would get you to the point where you would do something like:
Ultimately, it's about removing the shared account's ability to directly use the public/private key associated with the remote login. Whether that involves pushing the passwordless functionality to a different user and just control who can run the script as the newer user (as described above) or leaving it in place and having people use a different shared account, that's what needs to happen.
Hi @ all!
I've a problem with a ssh-connection.
I want to establish a ssh-connection between an AIX-System and an SunOS-System without a password.
The Users are different one's.
Command :
user1@server1 /home/user1 > ssh user2@server2
Is it possible?

cd-hit-2d-para.pl - divide a big clustering job into pieces to run cd-hit-2d or cd-hit-est-2d jobs
SYNOPSIS
cd-hit-2d-para.pl options
DESCRIPTION
This script divide a big clustering job into pieces and submit jobs to remote computers over a network to make it parallel. After
all the jobs finished, the script merge the clustering results as if you just run a single cd-hit-2d or cd-hit-est-2d.
You can also use it to divide big jobs on a single computer if your computer does not have enough RAM (with -L option).
Requirements:
1 When run this script over a network, the directory where you
run the scripts and the input files must be available on all the remote hosts with identical path.
2 If you choose "ssh" to submit jobs, you have to have
passwordless ssh to any remote host, see ssh manual to know how to set up passwordless ssh.
3 I suggest to use queuing system instead of ssh,
I currently support PBS and SGE
4 cd-hit-2d cd-hit-est-2d cd-hit-div cd-hit-div.pl must be
in same directory where this script is in.
Options
-i input filename for 1st db in fasta format, required
-i2 input filename for 2nd db in fasta format, required
-o output filename, required
--P program, "cd-hit-2d" or "cd-hit-est-2d", default "cd-hit-2d"
--B filename of list of hosts, requred unless -Q or -L option is supplied
--L number of cpus on local computer, default 0 when you are not running it over a cluster, you can use this option to divide a big
clustering jobs into small pieces, I suggest you just use "--L 1" unless you have enough RAM for each cpu
--S Number of segments to split 1st db into, default 2
--S2 Number of segments to split 2nd db into, default 8
--Q number of jobs to submit to queue queuing system, default 0 by default, the program use ssh mode to submit remote jobs
--T type of queuing system, "PBS", "SGE" are supported, default PBS
--R restart file, used after a crash of run
-h print this help
More cd-hit-2d/cd-hit-est-2d options can be speicified in command line
