[strongSwan] TLS handshake negotiation fail

Sun Feb 28 20:37:52 CET 2016

Hi, Noel
Or this "access denied" can come from pkcs format?pkcs#7 is used in this case, pkcs#12 should be used?

 Hi, Noel
Thanks.I complied again to isolate this problem.The reason why no item about certificates was shown by "ipsec listall" came from that I imported incorrect certificate from FreeRadius.Now I could get the item about CA by "ipsec install".
But I get the same error yet.
What does "access denied" mean?This is for TLS 1.2 but, it means:   access_denied      A valid certificate was received, but when access control was      applied, the sender decided not to proceed with negotiation.  This      message is always fatal.   from rfc5246
Access control?
I complied like this:./configure --prefix=/usr/local --sysconfdir=/usr/local/etc --enable-eap-identity --enable-eap-tls --enable-eap-peap --enable-eap-ttls --enable-eap-mschapv2 --enable-eap-md5

What does your config look like? Obviously, the RADIUS server only authenticates itself, not the authenticator.

Where is that exactly? Are you aware that the location of ipsec.d changes, depending on the compile time
sysconfdir and prefix settings?

Make sure you understand where charon things ipsec.d is actually.
