Behaviour with unavailable TCP destination
by ZeroUno 20 Jul '15

20 Jul '15

Hello, I was wondering what happens when you define a tcp() destination in syslog-ng.conf and then the destination is temporarily not available. I was not able to find the answer in the docs. Are any messages lost? Or are they kept somewhere and sent again when the destination becomes available again? Thank you. -- 01

Re: [syslog-ng] Using FIPS complaint OpenSSL with syslog-ng OSE
by Laszlo Budai 17 Jul '15

Hi, FIPS compliant OpenSSL is an openssl compiled and linked with FIPS object module. If syslog-ng not using disabled crypto functions (eg. md5) then it should work. Give it a try and if you will have some problems, just open an issue on our github page. regards, Laszlo Budai Sent from my HTC ----- Reply message ----- From: "Saurabh Shukla" <saurabh(a)purestorage.com> To: <syslog-ng(a)lists.balabit.hu> Subject: [syslog-ng] Using FIPS complaint OpenSSL with syslog-ng OSE Date: Thu, Jul 16, 2015 22:43 Hi, I see that syslog-ng OSE uses OpenSSL libraries for TLS support.

Host/port from environment variables
by Peter Flood 15 Jul '15

15 Jul '15

Hi I'm trying configure syslog-ng, I'd like to be able to use environment variables for host & port. I've tried the ones that work in the template formatter but it's not working (not suprisingly). Is there another way? destination d_my_dest { tcp("$(env MY_HOST)" port($(env MY_PORT)) # this doesn't work as you can't get env vars unless in a template tls(peer-verify(required-untrusted) ca_dir("/etc/syslog-ng/cert.d")) template(myTemplate)); }; Thanks

Trying to get json out of 3.7beta2
by Russell Fulton 08 Jul '15

08 Jul '15

Hi Thanks to various folks I managed to build 3.7b2 with json. I am now trying to convert my ELSA config to produce a parsed output in json that I can feed into Elastic Search. Having failed to make my full config work (I had to try ;) so I tried a basic one based on https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-… [ Aside: minor syntax error on this page — lnside log {} you can not name parser elements ] here is my conf: @version: 3.7 source s_json { network(port(1514) flags(no-parse)); }; destination d_json { file("/data/russell/test.json” template("$(format-json --scope dot-nv-pairs)\n")); }; log { source(s_json); parser { json-parser (prefix(".json.")); }; destination(d_json); }; I get no output and ‘stats’ shows: [rful011@secmgrprd01 ~]$ sudo /usr/local/syslog-ng/sbin/syslog-ng-ctl stats SourceName;SourceId;SourceInstance;State;Type;Number src.none;;;a;processed;0 src.none;;;a;stamp;0 source;s_json;;a;processed;19375 global;payload_reallocs;;a;processed;25710 global;msg_clones;;a;processed;0 destination;d_json;;a;processed;0 center;;queued;a;processed;0 global;sdata_updates;;a;processed;0 center;;received;a;processed;19375 global;internal_queue_length;;a;processed;19378 Which is the same as I get with my full config with lots of patterns. As usual am missing something basic!

configure for beta 2 not finding jsonc on RHEL 6

Hi I have installed the libjson-devel package via yum but ./configure says: checking for JSON: no the library is in /lib64 and headers in /usr/include/json-c/ I can’t figure out what configure options I need to get this to work. Thanks, Russell

syslog-ng 3.7.0beta2
by Budai, László 26 Jun '15

26 Jun '15

3.7.0beta2 This is the second beta release of the upcoming syslog-ng OSE 3.7 branch. Changes compared to the previous alpha release: Features - Added a geoip parser. - ssl_options inside tls() extended with the following set: no-sslv2, no-sslv3, no-tlsv1, no-tlsv11, no-tlsv12 - minimal libriemann-client version bumped from 1.0.0 to 1.6.0 - TLS support added to Riemann destination - timeout() option added to Riemann destination Fixes - SyslogNg.jar removed from the release tarball. - When the configured host was not available during the initialization of afsocket destination syslog-ng just didn't start. From now, syslog-ng starts in that case and will retry connecting to the host periodically. - When a not writeable file becomes writeable later, syslog-ng recognize it (with the help of reopen-timer) and delivers messages to the file without dropping those which were received during the file was not available. - Fixed a configure error around libsystemd-journal. - --disable-python option and other Python related fixes addded to configure - Retries fixed in SQL destination. In some circumstances when retry_sql_inserts was set to 1, after an insertion failure all incoming messages were dropped. - Added DOS/Windows line ending support in config. - Parallel build is supported for Python and Java destination drivers. - Fixed compilation failure on OpenBSD - Memory leak around reload and internal queueing mechanism has been fixed. - AMQP connection process fixed. - Fixed a potential abort when the localhost name cannot be detected. - Security issue fixed around $HOST. Tech details: When the name of the host is too long, the buffer we use to format the chained hostname is truncated. However snprintf() returns the length the result would be if no truncation happened, thus we will read uninitialized bytes off the stack when we use that pointer to set $HOST with log_msg_set_value(). There can be some security implications, like reading values from the stack that can help to craft further exploits, especially in the presense of address space randomization. It can also cause a DoS if the hostname length is soo large that we would read over the top-of-the-stack, which is probably not mmapped causing a SIGSEGV. - Journal entries containing name-value pairs without '=' caused syslog-ng to crash. Instead of crashing, syslog-ng just drop these nv pairs. Credits syslog-ng is developed as a community project, and as such it relies on volunteers, to do the work necessarily to produce syslog-ng. Reporting bugs, testing changes, writing code or simply providing feedback are all important contributions, so please if you are a user of syslog-ng, contribute. We would like to thank the following people for their contribution: Alex Badics, Andras Mitzki, Balazs Scheidler, Bence Tamas Gedai, Fabien Wernli, Gergely Nagy, Gergo Nagy, Gyorgy Pasztor, Istvan Adam Mozes, Laszlo Budai, Peter Czanik, Robert Fekete, Tibor Benke, Viktor Juhasz, Zoltan Pallagi. — View it on GitHub <https://github.com/balabit/syslog-ng/releases/tag/syslog-ng-3.7.0beta2>.
