Dear all, I don't want forwarding the syslog messages which contain the following to my local syslog, so I setup the filter like below ISDN-6-CONNECT ISDN-6-DISCONNECT changed by user However the messages contain the above are still show up in my local syslog file ForMe.log Below is from my syslog-ng.conf source s_network { network( transport("udp") port(514) flags(syslog_protocol) keep_hostname(yes) keep_timestamp(yes) use_dns(yes) use_fqdn(yes) ); }; destination d_ForMe_logs { file("/app/syslog-ng/custom/output/ForMe.log"); }; filter f_DoNotSendtoMe { not match("ISDN-6-CONNECT" value("MESSAGE")); or not match("ISDN-6-DISCONNECT" value("MESSAGE")); or not match("changed by user" value("MESSAGE")); }; log { source(s_network); filter(f_DoNotSendtoMe); destination(d_ForMe_logs); }; Do I missing any confing ?

If you would like to test before the upcoming release, you can create a deb package with our docker based package scripts: https://github.com/syslog-ng/syslog-ng/tree/master/dbld
depending on your platform, it would be "dbld/rules deb" or "dbld/rules deb-ubuntu-xenial"

Hi Raghu,
You are welcome! Thanks for the good idea. 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%2Fdow nload.opensuse.org%2Frepositories%2Fhome%3A%2Flaszlo_budai%3A%2Fsyslog -ng%2F&data=02%7C01%7Cgabor.nagy%40oneidentity.com%7Cfb559bbffddf430b0 7d408d74285c639%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C637051014 645459869&sdata=krct3nD%2BVSMEQG00R0VJO2D1CeLqITAi8ZNTI7mV1a8%3D&reser ved=0>

Hi Atilla,
I updated the code, compiled it and tested the changes. 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?
Thanks Raghu

Hi Raghu,
Currently we are not sending SNI extension in the Client Hello message.

Can you build syslog-ng from source? It would be great, if you tested the PR.

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.e xample.net&data=02%7C01%7Cgabor.nagy%40oneidentity.com%7Cfb559bbffddf4 30b07d408d74285c639%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C63705 1014645469860&sdata=RTiMaNycpB56zTGx2gmqeFESNI2QO3JvOvSXUyC2MRk%3D&res erved=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.e xample.net&data=02%7C01%7Cgabor.nagy%40oneidentity.com%7Cfb559bbffddf4 30b07d408d74285c639%7C91c369b51c9e439c989c1867ec606603%7C0%7C0%7C63705 1014645469860&sdata=RTiMaNycpB56zTGx2gmqeFESNI2QO3JvOvSXUyC2MRk%3D&res erved=0> as SNI to my remote server
Please advise
