Question Need Password-Less ssh with RSA-VPN
We have RSA SecureID softtoken key generator on my Windows machine.

It generates new keys every 1 minute.

Any HPUX server (be it ServerD or ServerP) requires my ID and the randomly generated RSA SecureID softtoken key from my Windows to login.

I login to ServerD.

Then I run a script on ServerD which has "ssh ServerP" which happens to be another HPUX box.

I have setup keys between ServerD and ServerP by generating both the keys on ServerD and copying the public key to ServerP's "authorized_keys" file.

However, it prompts me for the "Old Password". I am not sure how can I overcome this and directly login to ServerP with zero hinderences. I am also not sure what do I need to feed in the Old Password prompt that I get.

Can you please help provide a solution to this ?

rsa_check_key

RSA_check_key(3openssl) 					      OpenSSL						   RSA_check_key(3openssl)

NAME

       RSA_check_key - validate private RSA keys

SYNOPSIS

	#include <openssl/rsa.h>

	int RSA_check_key(RSA *rsa);

DESCRIPTION

       This function validates RSA keys. It checks that p and q are in fact prime, and that n = p*q.

       It also checks that d*e = 1 mod (p-1*q-1), and that dmp1, dmq1 and iqmp are set correctly or are NULL.

       As such, this function can not be used with any arbitrary RSA key object, even if it is otherwise fit for regular RSA operation. See NOTES
       for more information.

RETURN VALUE

       RSA_check_key() returns 1 if rsa is a valid RSA key, and 0 otherwise.  -1 is returned if an error occurs while checking the key.

       If the key is invalid or an error occurred, the reason code can be obtained using ERR_get_error(3).

NOTES

       This function does not work on RSA public keys that have only the modulus and public exponent elements populated. It performs integrity
       checks on all the RSA key material, so the RSA key structure must contain all the private key data too.

       Unlike most other RSA functions, this function does not work transparently with any underlying ENGINE implementation because it uses the
       key data in the RSA structure directly. An ENGINE implementation can override the way key data is stored and handled, and can even provide
       support for HSM keys - in which case the RSA structure may contain no key data at all! If the ENGINE in question is only being used for
       acceleration or analysis purposes, then in all likelihood the RSA key data is complete and untouched, but this can't be assumed in the gen-
       eral case.

BUGS

       A method of verifying the RSA key using opaque RSA API functions might need to be considered. Right now RSA_check_key() simply uses the RSA
       structure elements directly, bypassing the RSA_METHOD table altogether (and completely violating encapsulation and object-orientation in
       the process).  The best fix will probably be to introduce a "check_key()" handler to the RSA_METHOD function table so that alternative
       implementations can also provide their own verifiers.
