Hello, I have just came to 'syslog-ng' and I am having some troubles to setting it up. I am using the "syslog-ng.conf" provided by "slackbuilds.org", and I have add just few lines. Well, those lines make the daemon not to run. the error: ++++++++++++ Starting syslog-ng daemon: /usr/sbin/syslog-ng Error parsing source, source plugin s_router not found in /etc/syslog-ng/syslog-ng.conf at line 59, column 14: log { source{s_router}; destination{d_router}; }; ^^^^^^^^ syslog-ng documentation: http://www.balabit.com/support/documentation/?product=syslog-ng mailing list: https://lists.balabit.hu/mailman/listinfo/syslog-ng ******************* the release: ++++++++++++ root@liet:/etc/syslog-ng# syslog-ng -V syslog-ng 3.5.2 Installer-Version: 3.5.2 Revision: ssh+git://algernon@git.balabit/var/scm/git/syslog-ng/syslog-ng-ose--mainline--3.5#master#a31bdb7a7f57382a90305bd033753b2762469854 Compile-Date: Feb 28 2014 19:53:40 Available-Modules: afsocket-notls,afamqp,linux-kmsg-format,basicfuncs,affile,dbparser,afsocket-tls,csvparser,afsocket,afstomp,system-source,afmongodb,cryptofuncs,afprog,syslogformat,afuser,confgen Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-IPv6: on Enable-Spoof-Source: off Enable-TCP-Wrapper: off Enable-Linux-Caps: on Enable-Pcre: on ******************* And the config file (my lines remarked with <<<<<<): +++++++++++++++++ @version: 3.5 # Drop-in replacement for a stock Slackware syslog.conf # For info about the format of this file, see "man syslog-ng.conf" # Written by Mario Preksavec <mario(a)slackware.hr> options { flush_lines(0); time_reopen(60); log_fifo_size(10240); log_msg_size(8192); chain_hostnames(no); use_dns(no); use_fqdn(no); create_dirs(yes); keep_hostname(yes); owner("root"); group("root"); perm(0640); dir_perm(0755); stats_freq(0); check_hostname(yes); dns_cache(no); }; source s_router { udp(ip(192.168.1.1) port(514)); }; <<<<<<<<<<<<< source s_system { internal(); unix-dgram("/dev/log"); file("/proc/kmsg" program_override("kernel")); }; filter f_messages { level(info,notice) and not facility(authpriv,cron,mail,news); }; filter f_syslog { level(warn..emerg) and not facility(authpriv,cron,mail,news); }; filter f_debug { level(debug); }; filter f_authpriv { facility(authpriv); }; filter f_cron { facility(cron); }; filter f_mail { facility(mail); }; filter f_emerg { level(emerg); }; filter f_uucp { facility(uucp); }; destination d_messages { file("/var/log/messages"); }; destination d_syslog { file("/var/log/syslog"); }; destination d_debug { file("/var/log/debug"); }; destination d_secure { file("/var/log/secure"); }; destination d_cron { file("/var/log/cron"); }; destination d_maillog { file("/var/log/maillog"); }; destination d_usertty { usertty("*"); }; destination d_spooler { file("/var/log/spooler"); }; destination d_router { file("/var/log/router"); }; <<<<<<<<<<<<< ############ ## Router ########################### log { source{s_router}; destination{d_router}; }; <<<<<<<<<<<<< # Log anything 'info' or higher, but lower than 'warn'. # Exclude authpriv, cron, mail, and news.

Porposal (Rough Draft): Type Hinting from the start
by Rajul Srivastava 26 Feb '14

26 Feb '14

Hi all, I have come up with a very rough draft of a proposal for the project idea "Type Hinting from the start" which I have upload here: https://drive.google.com/file/d/0B2mFOuJDrIXmT1AzbngtUXp3eVk/edit?usp=shari… This is the preliminary draft, where I have tried to just list the background and a brief write-up about what I can understand about the project idea. I request you all to kindly take a look at it and I shall be very grateful to anyone who can give me suggestions about how may I go about the design and implementation details about this project. I have not included the timeline for the project, which I plan to do after I have finalized the design and implementation details in the proposal. I shall really be grateful for any suggestions and feedback. Thanking You, Kind regards, Rajul

Introduction
by Rajul Srivastava 25 Feb '14

25 Feb '14

Hi all, My name in Rajul, and I am a final year undergraduate student at the Indian Institute of Technology Kharagpur. I wish to participate in Google Summer of Code 2014, and while going through the list of organisations, I came across The syslog-ng project". I am proficient with programming languages C/C++, Python, Java, Groovy, Ruby. I am very interested in the fields of Algorithms, Machine Learning, Complex Networks, Information Retrieval. I have always been interested in programming and in the past I have participated in Google Summer of Code 2012, with the organisation Network Time Foundation,working on the project "improving the Logging/Debugging System of Network Time Protocol Software". I have also interned in the Global Technology division of Barclays, during the summers of 2013, working with the Market Risk IT team. Besides I have worked on a few Research projects in the fields of Computational Finance, Complex Networks, and Computational Chemistry. I am currently working on my Thesis project in the field of Computational Sciences on a project titled "Network Analysis of Chemical Reactions". I have had courses in the fields of Programming and Data Structures, Complex Networks, Distributed Systems, Algorithms, Operations Research in the past. I have gone through the list of project ideas and I found most of the project ideas very interesting. Although I find all the projects listed worth a while, I am particularly interested in the "Configuration Visualization" and "Type Hinting from the start" projects. I suppose that my programming background is suitable for these projects. I shall be grateful if anyone can help me and give me reference to the literature that I may use and also shed some light on how I can go about making a successful proposal. Thanks!! Best Regards, Rajul -- Rajul Final year Undergraduate Student, Indian Institute of Technology Kharagpur

Per-destination log_msg_size?
by David Schweikert 21 Feb '14

21 Feb '14

Hi, We have some setups where we want to have a large log_msg_size, but need to send some logs to an external party which only can handle standard BSD syslog messages with a maximum size of 1024 bytes. Question: would it be possible to add a per-destination log-msg-size to truncate the messages on a per-destination basis? I think that it would be very useful. Something like: destination d_remote { udp("192.168.65.10" port(514) log_msg_size(1024)); }; Do you find it a good idea and is there any chance that this might be implemented? Thanks David

Re: [syslog-ng] syslog-ng Digest, Vol 106, Issue 12

Why not stand up a test server and add it to the logging configs of the non-working and a couple of working switches? It could be a VM, since it won't have much load. You could also capture the log messages and play them back at the test server without impacting your production server or data archives. -tcs On 2/18/14 3:12 PM, syslog-ng-request(a)lists.balabit.hu wrote: > Date: Tue, 18 Feb 2014 15:12:50 -0500 > From: Chris Moody<chris(a)node-nine.com> > Subject: [syslog-ng] need help debugging some network received logs > that aren't writing to files > To: Syslog-ng users' and developers' mailing list > <syslog-ng(a)lists.balabit.hu> > Message-ID:<5303BEC2.9010405(a)node-nine.com> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > Hello. > > First off, thanks a __TON__ for syslog-ng.

log path with two destinations - flow control problem
by Tomáš Novosad 18 Feb '14

18 Feb '14

Hello to all i'm trying to set syslog to store sendmaill messages into PostgreSQL tables. One simple table (tableA) which stores all messages, and another table (tableB) which stores only some relevant iformation. All messages are parsed in my parser, then logged into tableA, then checked against the filter, an those messages which pass are logged into tableB. it all looks like this: log { source(pipe_load); filter(f_sendmail); #-- basic filter for sendmail program parser(maillog); #-- parse message details destination(maillog_base); #-- store message in tableA - basic info only filter(f_sendmail_from_or_to); #-- filter only messages which have "from" or "to" address defined destination(maillog_detail); #-- strore the deatiled info into tableB flags(flow-control); } filterinhg itself works fine, but i have problem with flow-control Messages are send from file (old archived maillog) into syslog pipe source. Problemm is, that alhough flow-control is enabled, messages get droped on the maillog_base destination. Im doing "cat old_maillog > syslog-pile" where old_maillog has approx 1 800 000 records, but only about 400 000 records gets logged into tableA. Flow control does not seem to work in this scenario. In case when i comment-out lines with filter(f_sendmail_from_or_to) and destination(maillog_detail) effectively disabling logging into the 2nd table, all messages from input file are processed and stored into tableA. The flow control works fine in this case. Is there something wrong with such filtering and storing only some messages in the 2nd destination? I also thought about having two different log path for each table, but in that case, the parsing of the message should be done twice, which i want to avoid. My question is, if is it OK to use filtering like in my example, - filter - than destination - then filter again - then another destination + flow control Many thanks in advance -- Tomáš Novosad LinuxBox.cz, s.r.o. 28. října 168, 709 00 Ostrava tel.: +420 591 166 221 mobil: +420 737 238 655 email: tomas.novosad(a)linuxbox.cz jabber: novosad(a)linuxbox.cz www.linuxbox.cz mobil servis: +420 737 238 656 email servis: servis(a)linuxbox.cz
