If everything goes well, this feature will be released in version 3.24, in 3-4 weeks. The packaging happens at the same time, you will find the 3.24 installer at https://download.opensuse.org/repositories/home:/laszlo_budai:/syslog-ng/<https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdownload.opensuse.org%2Frepositories%2Fhome%3A%2Flaszlo_budai%3A%2Fsyslog-ng%2F&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090791204&sdata=H%2BQFpJOnTdhGOgMiXXimyDRJRsJMs3ABr3MNdUZ0h%2BY%3D&reserved=0> Best regards, Attila ________________________________ From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> on behalf of Raghunath Adhyapak <funduraghu@gmail.com> Sent: Wednesday, September 18, 2019 12:50 PM To: Syslog-ng users' and developers' mailing list <syslog-ng@lists.balabit.hu> Subject: Re: [syslog-ng] Enable SNI (Server Name Identification) in TLS connection CAUTION: This email originated from outside of the organization.

The changes works as expected. Thanks for the addressing the issue in such a short time. Follow-up question: When will this change get merged into the master branch? Also, when will this get packaged in Debian package?

Do not follow guidance, click links, or open attachments unless you recognize the sender and know the content is safe. Hi, I am using TLS over TCP connection to forward my syslog events to a remote server. My remote server uses SNI (Server Name Identification) to route connections/events to one of the available backend servers. I observe that syslog-ng doesn't send SNI during TLS handshake. How can I enable it? My configuration is as follows: =================================== source s_net { syslog(transport(udp) port(1514)); }; destination d_tcp { tcp( "XX.example.net<https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2FXX.example.net&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090801199&sdata=kKc2XxSr%2FnS%2BbFmSCXXqka9t17oLsCrDmViLjQdQfQI%3D&reserved=0>" port(96) tls( peer-verify(required-untrusted) ca_dir("/etc/syslog-ng/ssl") key-file("/etc/syslog-ng/ssl/globaltest/XX.example.net.key.pem") cert-file("/etc/syslog-ng/ssl/globaltest/XX.example.net.cert.pem") ) ); }; log { source(s_net); destination(d_tcp); }; =================================== I want syslog-ng to send XX.example.net<https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2FXX.example.net&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090811194&sdata=OMGWyTrbUz5J40CVui56wWoLSzbSQXj7EcWzQGNDKQc%3D&reserved=0> as SNI to my remote server Please advise Thanks Raghu ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng<https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.balabit.hu%2Fmailman%2Flistinfo%2Fsyslog-ng&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090821195&sdata=bYI0oeeeoLjifgXSlm8%2BUfaAMEk%2FPuOqo966%2FaOCRMI%3D&reserved=0> Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng<https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.balabit.com%2Fsupport%2Fdocumentation%2F%3Fproduct%3Dsyslog-ng&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090821195&sdata=ZJda2Cox1NHyYkmtThHPC0nu6HIdQ9LK7oJqDXHb4CM%3D&reserved=0> FAQ: http://www.balabit.com/wiki/syslog-ng-faq<https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.balabit.com%2Fwiki%2Fsyslog-ng-faq&data=02%7C01%7CAttila.Szakacs%40oneidentity.com%7C9a139415a6fc4def5c9208d73c2b528e%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637044029090831186&sdata=yVv8HfegV4%2B0g1U2XAsWXRc1CxRVEJ7chniTvJdizMU%3D&reserved=0>
