Subject RE: Trafficserver and HTTPS (SSL Termination)
Date Mon, 25 Mar 2013 17:37:05 GMT
Hi All,

I'm not sure why SSL handshake freezes after Client hello. I did some changes in SSL Termination
section.

[root@cacheserver trafficserver]# curl -3kvI https://www.web1.com
* About to connect() to www.web1.com port 443
*   Trying 172.16.89.32... connected
* Connected to www.web1.com (172.16.89.32) port 443

*   CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none
* SSLv3, TLS handshake, Client hello (1):

Hi Anshu,

The permission are same for cert/key on both the server.

@marswrk,

I changed the certificate to PEM format with no password and restarted Traffiserver and webserver,
but still it is not working. I'm not using ssl_multicert.config.

Subject: Re: Trafficserver and HTTPS (SSL Termination)

I had a problem with my https too. I fixed by making sure certificate file in PEM format.
Also removed password that was used to protect cert.
Did you restart trafficserver? My first config did not take effect and the port was not actually
listening yet.

And since it was a work network also needed to get the firewall permissions updated.

I joined recently did I miss the ssl_multicert.config post?
Were there any relevant error messages in the log files?

Subject: Re: Trafficserver and HTTPS (SSL Termination)

Had seen this issue a while back, the file permissions of the SSL cert files/keys were the
main culprit. The file permisssion for the certs/keys should be the same as how they are under
http server. (the read permission to all for key was one of the problems).

Hi All,

I'm trying to build the cache solution using Apache Traffic Server (ATS). I'm trying to build
a test environment with 2 servers. I have installed ATS-3.2 on one of the server (Cacheserver)
and Apache web on the other (Webserver).

On Webserver, I have configure two website www.web1.com<http://www.web1.com> and www.web2.com<http://www.web2.com>.
It is configured to listen on port 4000, 40001 for HTTP requests and 5000, 5001 for HTTPS
requests. I'm using self-signed certificate for those website.

On Cacheserver, I have configured Traffic Server to listen on port 80 and 443 for HTTP and
HTTPS requests.

Both the websites are working fine when I point web browser to  webserver(HTTP & HTPPS
requests), but when I point it to Cacheserver HTTP request works, but HTTPS requests end up
with error.

[root@cacheserver ~]# curl -k -v https://www.web1.com
* About to connect() to www.web1.com<http://www.web1.com> port 443
*   Trying 172.16.89.32... connected

* Closing connection #0
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

All the certificates and keys are located under etc/trafficserver/ssl  on Cacheserver. I've
copied webserver-cert.crt and webserver-key.key from the Webserver.

[root@cacheserver ls -l /opt/ats/etc/trafficserver/ssl
-rw-r--r-- 1 root root 6334 Mar 21 14:48 cachesvr-bundle.crt

Client --Http--> Cache server --Http-->Origin server (http://www.web1.com and http://www.web2.com)
Client --Https--> Cache server --Https-->Origin server (http://www.web1.com and http://www.web2.com)

But it doesn't work with https. What I'm doing wrong here.

Let me know if anything is not clear.

Thanks,
Ketan
