Hi Martin,
I downloaded the openssl-1.0.0d.tar.gz. Build the openssl with
enabled the ec and ecdh (Elliptic curve Diffie–Hellman Group) support as stated
below.
        1. ./config enable-ec enable-ecdh
        2. make
        3. make test
        4. make install
 
But upon checking whether ECDH has been enabled or not via #openssl
ciphers –v ‘ECDH’ , it complains with the following error
Error in cipher list
3079456476: error: 1410DB9: SSL
routines:SSL_CTX_set_cipher_list:no cipher match:ssl_lib.c:1282:
 
I need to use openssl’s ECDH to enhance the IKE (v2) tunnel
setup rate using strongswan(5.0.4)'s load tester plugin. I am using Fedora 
Linux (kernel version: 2.6.33.3-85.fc13.i686). Please
suggest if I am wrong or missing something. Thanks in advance for your support
and response.
 
Regards,
Chinmaya

Thanks Martin for your prompt response. Let me follow up your suggestions and 
try again.

Most likely your Fedora OpenSSL comes without Elliptic Curve support.

You'll have to build OpenSSL yourself, or look for third party packages
providing OpenSSL with EC enabled.
