Syslog-ng 3.7.2 install fails on U12.04
by Varugis Kurien 11 Nov '16

11 Nov '16

When installing from the repository here (http://download.opensuse.org/repositories/home:/laszlo_budai:/syslog-ng/xUb…) the install fails to install syslog-ng3.7.2 with the message: rm_conffile voodoo unsupported for package syslog-ng-mod-python! -- This appears to be coming when installing syslog-ng-mod-python due to a failure in a preinstallation script. How can I fix this?

Possible elementary question
by Varugis Kurien 10 Nov '16

10 Nov '16

I'm having some conniptions doing central logging using syslog-ng. Here is the scenario: 1. I generate logs using syslog-ng on local servers and then send them to a log-destination server. Here is an example of some of the conf files on the generating server: more iptables.log.conf source s_var_log_iptables.log { file("/var/log/iptables.log" program-override(var_log_iptables.log) flags(no-parse)); }; log { source(s_var_log_iptables.log); destination(d_midfin_logger_2); }; more midfin_logger_2.conf template t_sdx_tagged { template("$ISODATE $HOST $PROGRAM $MSG "); template_escape(no); }; destination d_midfin_logger_2 { tcp( "10.4.16.161" port(514) template(t_sdx_tagged)); }; What I am trying to do on the log host is to: 1. Segregate at the top level by host. For each such host: * Split the logs into different directories so that for example, I'll have one directory for the audit log from that host, another for iptables etc - so that under each host I'll have /var/log/iptables.log etc. I've been unable to grok the documentation to figure out quite how to do this and would really appreciate some help. thanks vk ==

linux-audit-parser not found on stock install of Ubuntu 16.04
by Varugis Kurien 02 Nov '16

02 Nov '16

When using a freshly installed version of U16.04, I found that the linux audit log parser does not seem to be installed. For example: syslog-ng --module-registry|grep audit <-- returns nothing == 1. This started because I experienced a failure when trying to enable the linux audit parser: Error parsing parser expression, parser plugin linux-audit-parser not found in /etc/syslog-ng/conf.d/auditd.log.conf at line 3, column 8: included from /etc/syslog-ng/syslog-ng.conf line 164, column 1 linux-audit-parser(prefix(".auditd.")); 2. The corresponding conf file is below: source s_var_log_audit.log { file("/var/log/audit/audit.log" flags(no-parse)); }; parser p_audit_syslog_parser { linux-audit-parser(prefix(".auditd.")); }; log { source(s_var_log_audit.log); parser(p_audit_syslog_parser); destination(d_midfin_logger_2); }; The officially supported version of syslog-ng in ubuntu is 3.5.1. == syslog-ng 3.5.6 Installer-Version: 3.5.6 Revision: 3.5.6-2.1 [@416d315] (Ubuntu/16.04) Compile-Date: Oct 24 2015 03:49:19 Available-Modules: json-plugin,csvparser,system-source,tfgeoip,afsocket-notls,afamqp,basicfuncs,affile,afsocket-tls,dbparser,afmongodb,cryptofuncs,afsmtp,linux-kmsg-format,afuser,redis,afsocket,afstomp,sysl\ ogformat,confgen,afprog,afsql Enable-Debug: off Enable-GProf: off Enable-Memtrace: off Enable-IPv6: on Enable-Spoof-Source: on Enable-TCP-Wrapper: on Enable-Linux-Caps: on Enable-Pcre: on Do I need to install an unofficial version or is there some elementary mistake that I am making. thanks Varugis

syslog-ng fails logging to existing sqlite database
by Andrea Laini 19 Oct '16

19 Oct '16

Hello everybody, I would like to ask you a question about libdbi (version 0.8.4.1 with libdbi-drivers 0.8.3). I'm using syslog-ng 3.5.4.1 on my Yocto Poky 1.7 Linux distro. I need to log my data into a sqlite3 database and everything works fine, but the database has not be written: no log data stored. According to debug infos, it seems that syslog-ng recognizes that the database exists, connects to it, found (with the sql statement "SELECT * FROM tableName WHERE 0=1) that the table named "tableName" exists but it gets an error when verifying columns' names; so it tries to add a column with that name to the table, but the operation fails since this column already exists. I've googled and search on the web, but I've found nothing interesting. Trying syslog-ng 3.6.4 doesn't change anything, while using libdbi 0.9.0 returns an error when compiling due to mismatch between function signature in the source and header file. Have you any suggestions? Thanks in advance, Regards Andrea Please be informed that our offices will be closed for National Holidays from Monday 31/10/16 to Tuesday 01/11/16 included. We will be back on Wednesday 02/11/16. Vi ricordiamo che saremo chiusi per festività i giorni lunedì 31/10/16 e martedì 01/11/16. Saremo nuovamente operativi da mercoledì 02/11/16.
