Hi All,

I want to use StrongSwan as a client to set up VPN tunnel with other device. 
And I configure the authentication mode as EAP_MD5. However, I met some 
problems. My configuration file is as follows:
conn test
         leftauth=eap
         eap_identity=aaron
                   rightauth=psk
                   keyexchange=ikev2
                   left=x.x.x.x
                   leftsourceip=%config
                   right=y.y.y.y
                   rightsubnet=192.168.168.0/24
                   auto=add

My ipsec.secrets is as follows:
                  x.x.x.x y.y.y.y : PSK "123456"
                  aaron : EAP "password"
And also I enable the eap plugin in strongswan.conf

But I capture the packet and found that strongswan send a eap response payload  
to peer only with 22 octets which does not include any information about the 
eap_identity. Refer to the RFC that says :
A summary of the Challenge and Response packet format is shown below.
   The fields are transmitted from left to right.

   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |     Code      |  Identifier   |            Length             |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |  Value-Size   |  Value ...
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |  Name ...
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

I can not see the field Name in the packet. Is there any problem?


thanks
