Do not use rexec and DO NOT USE .netrc-files at all, they are a severe security hole.

Install ssh on all machine (download at www.bullfreeware.com for instance), exchange keys and then issue:

Code:
#!/bin/ksh

ssh remoteserver -l userA "who am i"

ssh remoteserver -l userB "who am i"

exit 0

Hope this helps.

ssh-import-id(1)						    ssh-import							  ssh-import-id(1)

NAME
ssh-import-id - retrieve one or more public keys from a public keyserver (Launchpad.net by default) and append them to the current user's authorized_keys file (or some other specified file) SYNOPSIS
ssh-import-id [options] USER_ID_1 [USER_ID_2] ... [USER_ID_n] OPTIONS
-h | --help usage -o | --output F write output to file 'F' (default ~/.ssh/authorized_keys, use "-" for standard out) DESCRIPTION
This utility will securely contact a public keyserver (https://launchpad.net by default) and retrieve one or more user's public keys, and append these to the current user's ~/.ssh/authorized_keys file. The system administrator can change the source URL used by ssh-import-id(1) by editing the configuration file, /etc/ssh/ssh_import_id, which is sourced to obtain the value of URL. By default, URL="https://launchpad.net/~%s/+sshkeys". Note that this url really MUST be a secure, https url with a valid, signed certificate or else your system will be vulnerable to man-in-the-middle attacks! The "%s" will be populated by ssh-import-id(1) with the value(s) of USER_ID_1 [USER_ID_2] ... [USER_ID_n]. SEE ALSO
