Hi Specialists!  
I'm trying to send data from Logstash using SSL/TLS to a rsyslog server (it needs certificates). I read a lot of articles/posts/official docs/etc and couldn't found the way to accomplish this with Logstash.  
There is a Github post (an enhancement ) that says this feature is included in the output plugins of TCP and Syslog ([https://github.com/logstash-plugins/logstash-output-tcp/pull/3](https://github.com/logstash-plugins/logstash-output-tcp/pull/3)) but I couldnt found the way to download this feature.  
I'm trying to do something like this:

output {  
syslog {  
facility =\> "local7"  
severity =\> "informational"  
msgid =\> ""  
procid =\> ""  
appname =\> "myAppRamon"  
protocol =\> tcp {  
host =\> ""  
port =\> ""  
ssl\_cert =\> "/etc/ssl/private/server.crt"  
ssl\_key =\> "/etc/ssl/private/server.key"  
ssl\_extra\_chain\_certs =\> ["/etc/ssl/private/ca.crt"]  
}

```
    }

```

OR

output {  
syslog {  
facility =\> "local7"  
severity =\> "informational"  
host =\> ""  
port =\> ""  
msgid =\> ""  
procid =\> ""  
appname =\> "myAppRamon"  
ssl\_cert =\> "/etc/ssl/private/server.crt"  
ssl\_key =\> "/etc/ssl/private/server.key"  
ssl\_extra\_chain\_certs =\> ["/etc/ssl/private/ca.crt"]  
protocol =\> "tcp"  
}  
Thank you very much!

Regards,  
Ramon

The latter is the closest, but `protocol` needs to be "ssl-tcp". You need at least v2.1.1 of the syslog output plugin. I don't know why the documentation from that release hasn't been published at [https://www.elastic.co/guide/en/logstash/master/plugins-outputs-syslog.html](https://www.elastic.co/guide/en/logstash/master/plugins-outputs-syslog.html).

Thank you very much Magnus!  
So just putting "ssl-tcp" should work?  
output {  
syslog {  
facility =\> "local7"  
severity =\> "informational"  
host =\> ""  
port =\> ""  
msgid =\> ""  
procid =\> ""  
appname =\> "myAppRamon"  
ssl\_cert =\> "/etc/ssl/private/server.crt"  
ssl\_key =\> "/etc/ssl/private/server.key"  
ssl\_extra\_chain\_certs =\> ["/etc/ssl/private/ca.crt"]  
**protocol =\> "ssl-tcp"**  
}  
Thanks in advance!

Just did the test...it works perfectly, I just change ssl\_extra\_chain\_certs to ssl\_cacert

Best regards and thanks!
