DDNS Update over https (ssl cert problem)

Unanswered Question
Oct 20th, 2009

Hello,

I tryed to setup that my c836 router use https to send host updates crypted to members.dyndns.org but it will not work.

I used the following howto:

http://www.dyndns.com/support/kb/configuring_cisco_https.html

and selected the Root 4 - Equifax Secure eBusiness CA-1 (Base-64 encoded X.509) to copy / paste from http://www.geotrust.com/resources/root-certificates/ to my router.

show debugging

Dynamic DNS debugging is on

SSL Subsystem:

SSL Handshake Message debugging is on

SSL Error debugging is on

SSL Event debugging is on

That give me the following output:

I confirm similar behavior...need to be able to configure the SSL client to force accept:

Here is a copy my blog post on the topic...

I got aroud the issue with HTTPs in the DDNS client by manually creating a trustpoit and importing the certificate of the signing cert used on the HTTPs/Apache service on my domain provider (PairNIC)'s web service

----

Here is a simple guide of how to integrate your Cisco IOS router platform with your PairNIC-managed domain name.

This  is a useful if you are buying commodity broadband connectivity from a  hetergenous selection of regional service providers that use DHCP on a  bridged ethernet WAN (Verizon FIOS, Comcast broadband, Consolidated  Communications metro ethernet)

As you can see below,  PairNIC makes-available a REST-style HTTP WebServices URL that you can  pass simple GET-style calls to with the HTTP client in Cisco IOS  routers.

NOTE: The password field below is not your  PairNIC password, but instead, a dynamic key that is generated when you  turn on Custom DNS for your domain and enable dynamic updates

NOTE: PairNIC domains are supported.  Pair.com-managed-domains are not supported. 

This works out, because you likely want to have a separate domain name for WAN DDNS updates

NOTE:  You do not need to have an A-record in place already, despite the  ambiguously named '/update' method-call below, it will actually create  records on-demand.

NOTE: I'm not sure if there is an erase/delete/destroy/remove function call -- Waiting to hear back from Pair

NOTE:  At this point, we see the HTTP CURL/WGET client in Cisco IOS doing what  it _should_ do -- however, it will fail because the SSL Library in IOS  (OpenSSL) doesnt ship with a proper set of trusted root CA Certificates

To  fix(*) this, we simply import and explicitly-trust the certificate that  signed the SSL cert used on PairNIC's cert for 'dynamic.pairnic.com'

(*) Its more of a cheap hack.  Cisco can fix by shipping a CA Cert Chain with OCSP/CRL enabled by default.

br00# conf t

br00(conf)# no crypto pki trustpoint CA-AddTrust-UserTrust

br00(conf)# crypto pki  trustpoint CA-AddTrust-UserTrust

enrollment terminal pem

revocation-check none

crl optional

br00(ca-trustpoint)#crypto pki authenticate CA-AddTrust-UserTrust

Enter the base 64 encoded CA certificate.

End with a blank line or the word "quit" on a line by itself

   [PEM Certificate here -- see below for openssl(1) command to extract on UNIX]

Trustpoint 'CA-AddTrust-UserTrust' is a subordinate CA and holds a non self signed cert

Certificate has the following attributes:

       Fingerprint MD5: F2CB531D 39AA97FF 39900B79 1319ABD4

      Fingerprint SHA1: 10189D78 180A33A9 DF7219F0 6D15FC86 5C9A6160

% Do you accept this certificate? [yes/no]: yes

Trustpoint CA certificate accepted.

% Certificate successfully imported

And here is functional real-world example of this working:
