After syslog, now rsyslog comes pre-built with the Linux systems, meant for local and remote logging. Syslog-ng TLS Configuration – sending syslog-ng logs using TLS Encryption. This simplification permits us to use a somewhat less complicated way of generating the machine certificates. In any system, you will want to (a) log the system and application logs on the local machine, and/or (b) log the system and application logs to a remote machine. The client LDAP libraries are broken in EL6 such that, if any 128 bit ciphers are present in the cipher string, it will fall back to SSF=128 for connecting to an LDAP server.

There seems to be something wrong with my Description of problem: rsyslogd has an option to receive syslog via a TLS tunnel using the gnuTLS engine eg: "$DefaultNetstreamDriver gtls". Verify your SSL, TLS & Ciphers implementation. Don't use rsyslog on BSDs or on anything except Linux! Either use native syslog or if you need something more powerful use sysutils/syslog-ng. The certificate must contain serverAuth in its key usage extension. 0 and therefore you must set a monitor extension value explicitly by setting "ssl-version=10" in the NSX Load Balancer configuration. CIPHER SUITE NAMES.

For SSL/TLS connections, cipher suites determine for a major part how secure the connection will be. a web browser) advertises, to the server, the TLS versions and cipher suites it supports. Thanks for the reply, I am trying to disable all the ciphers and then only enable the ciphers captured by the HIGH, SSLv3, TLSv1, MEDIUM, and SSLv2 list (these are maintained by the openssl guys i think When a client (Citrix Workspace app or StoreFront) connects and sends a list of supported TLS cipher suites, the VDA matches one of the client’s cipher suites with one of the cipher suites in its own list of configured cipher suites, and accepts the connection. Please note that in theory it should be compatible with other, non IETF syslog-transport-tls implementations. While in this verbose mode your host's syslog engine (rsyslog) may have a hard time keeping up and may drop messages: rsyslogd-2177: imuxsock lost 228 messages from pid 2547 due to rate-limiting This can be accomplished using Transport Layer Security (TLS). com) If you're looking to encrypt syslog transmissions between client and server, you can do so via rsyslog with TLS.

Older OSes like CentOS 5 do not have support, but CentOS 6 and higher do. TLS_DH_* and TLS_ECDH_* cipher suites are different (mind the lack of 'E' after the 'DH'). The entire sequence which involves setting up the session identifier, TLS protocol version, negotiating the cipher suite, certificate authentication of the peers and cryptographic key exchange between peers is called a TLS Handshake. But I believe that the problem is that you are mixing old and new syntax in one Remote Syslog over TLS setup guide strict – allows only NIAP/FIPS/TIC/UCAPL compliant TLS versions and cipher suites.
