OOps! Skipping breakfast was a bad idea. I mistakenly edited my local
ipsec.config ( I am sshing other two linux machines from third red hat
machine). After moving to right machine and right config file I am able to
move ahead but getting two different error messages when I --upping the
ipsec connection:

Ubuntu ( signature check ( ) failed(wrong key)
tried AQ-----
Red hat machine( Can't find the private key from the NSS CERT
(err -12285)

Now I am not sure which side is culprit or if both the error r genuine. Any
