Thanks Bazi. I would like to analyze little more on syslog-ng log files related to TLS. Could you please let me know how to enable debug logs in syslog-ng. I have one more query on ssl option. There is a TLS options in 3.7.2 , ssl-options() which is used for setting ssl option. Options are no-sslv2, no-sslv3, no-tlsv1, no-tlsv11, no-tlsv12 and by default option is no-sslv2. Hope my understanding is correct. I referred the following link https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-g... Could you please let me know how to set ssl-option in syslog-ng 3.6. I didn’t find similar option there. Currently my syslog-ng server is 3.6.2 and client is 3.7.2 Regards, Girish From: syslog-ng-bounces@lists.balabit.hu [mailto:syslog-ng-bounces@lists.balabit.hu] On Behalf Of Scheidler, Balázs Sent: Monday, March 07, 2016 1:17 PM To: Syslog-ng users' and developers' mailing list Subject: Re: [syslog-ng] Syslog over TLS : Protocol is TCP and TLS Well, if you open the payload of the initial packages (e.g. after the SYN-SYNACK-ACK handshake), you should see binary stuff instead of plain text log messages. -- Bazsi On Mon, Mar 7, 2016 at 7:07 AM, Girish Kumar <girish.kumar@al-enterprise.com<mailto:girish.kumar@al-enterprise.com>> wrote: Hi All, Finally I was able to setup syslog-ng client and server. Communicate over TLS. Thanks for all your help. In wireshark capture I am seeing all protocol as TCP and not as TLS. Please let me know whether my communication has happened over TLS.
