note that with v8 devel rsyslog-gnutls is obsolete and should be uninstalled (it's rolled into the main rsyslog package now)

Subject: Re: [rsyslog] TCP Encryption Netstream Errors

Hi Barry,

I remember seeing this error, but I don't remember the context. Do you have
the rsyslog-gnutls package installed? Or did you enable gnutls when
compiling it?

If yes, can you double-check the validity of your certificate. I see a
strange issue being reported in this thread:
http://kb.monitorware.com/rsyslog-with-tls-does-not-work-for-t12092.html

If these don't help, can you say more about your OS and GnuTLS versions?

Best regards,
Radu

Hi all,

I was wondering if I could request some assistance.

Currently, I am trying to setup TCP encryption and I get the following
error on my rsyslog server when the client is trying to send encrypted TCP
log events.

<Date> <server>: netsteam session 0x7fae50001740 will be closed due to
error [try http://www.rsyslog.com/e/2089]
<Date> <server>: netsteam session 0x7fae50002db0 will be closed due to
error [try http://www.rsyslog.com/e/2089]
<Date> <server>: netsteam session 0x7fae500097a0 will be closed due to
error [try http://www.rsyslog.com/e/2089]

Web research states that there should be an error message preceding this
error. I don't get any error messages prior to this.

My Server config is
Rsyslog V7.6.3 (GNUTLS V2.8.5)
$DefaultNetstreamDriver gtls
$DefaultNetstreamDriverCAFile <Path to CA PEM>
$DefaultNetstreamDriverCertFile <Path to Cert>
$DefaultNetstreamDriverKeyFile <Path to Key>

module(load="imtcp" MaxListeners="2000" StreamDriver.Name="gtls"
StreamDriver.Mode="1" StreamDriver.AuthMode="X509/name")
input(type-"imtcp" port="6173" name="tcp-tls")

My client config is
Rsyslog V5.8.10 (gnuTLSV2.8.5)
$DefaultNetstreamDriver gtls
$DefaultNetstreamDriverCAFile <Path to CA PEM>
$DefaultNetstreamDriverCertFile <Path to Cert>
$DefaultNetstreamDriverKeyFile <Path to Key>
$ActionSendStreamDriverAuthMode x509/name
$ActionSendSteamDriverMode 1

*.info;mail.none;authpriv.none;cron.none        /var/log/messages
&   @@<rsyslog_server>:6173;VLMessagesFwdFmt

The client is the bog standard rsyslog client as delivered on my centos
test machine while the server (which is the same OS) has been upgraded to
the V7.6.3 release from the rsyslog website.
My CA and certificates for testing is one created using openssl.

Any ideas would be appreciated.
