Sorry if this has been asked before, but I couldn't find anything related.I'm after NXLOG version CE 2.9.1716 for Windows however only Ubuntu & Debian is available from the download section. Does anybody know how I can obtain the Windows file?

HiI have configured compression and encryption for locally stored logs, and it seems to be working fine. However, when I run the command c:\program files\nxlog\nxlog-processor.exe -c d:\data\decrypted.conf, I encounter an error while attempting to decrypt the currently active file. The error message reads: 'error [im_file:enc_in] Crypto SSL error: error:0606506D:digital envelope routines:EVP_DecryptFinal_ex:wrong final block length.' Despite this error, the file is decrypted successfully, and we are able to read the log file clearly. Could you please advise on the meaning of this error? I have not encountered any errors for older encrypted files.

Hello everyone,I'm trying to solve a problem that seems simple.I would like to log Windows events on two different log servers. I would like to send all relevant logs to a Graylog but without the MSSQL logs. These are filtered and sent to another Graylog.Filtering by “MSSQL-ONLY” works fine, but dropping MSSQL events does not work. I get all logs including MSSQL an the "logs" output.Any idea? Windows Server 2022, nxlog-ce-3.2.2329.msi define ROOT C:\Program Files\nxlog define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf define LOGDIR %ROOT%\data define LOGFILE %LOGDIR%\nxlog.log LogFile %LOGFILE% Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data <Extension gelf> Module xm_gelf </Extension> <Input eventlog> Module im_msvistalog Query <QueryList> <Query Id="0"> <Select Path="Application"></Select> <Select Path="System"></Select> <Select Path="Security"></Select> <Select Path="Microsoft-Windows-Windows Defender/Operational"></Select> </Query> </QueryList> <Exec> if ($SourceName = "SQLSERVER") drop(); </Exec> </Input> <Input sqllog> Module im_msvistalog Query <QueryList> <Query Id="0"> <Select Path="Application">*[System[Provider[@Name='MSSQLSERVER']]]</Select> </Query> </QueryList> </Input> <Output logs> Module om_tcp Host graylog01.something.com Port 12202 OutputType GELF_TCP Exec $Hostname = 'XYZ.somthing.com'; </Output> <Output sqllogs> Module om_tcp Host graylog02.something.com Port 12202 OutputType GELF_TCP Exec $Hostname = 'XYZ.somthing.com'; </Output> <Route eventlog_to_udp> Path eventlog => logs </Route> <Route sqllog_to_udp> Path sqllog => sqllogs </Route>

We have configured  NXLog to monitor DHCP server logs and  sends it to two different destinations using TCP:what is the correct way of routing the output to two diffrent distnations..<Output out1>   Module      om_tcp   Host        destination1   Port       XXX  </Output><Output out2>   Module      om_tcp   Host        destination2   Port        XXXX   </Output><Route route1>   Path        input1 => out1   Path        input2 => out2</Route>

I am experiencing a problem with the NXLog Graylog sidecarwhere large CSV messages are being truncated when sent to Graylog via im_file and xm_gelf. The issue occurs regardless of whether I use UDP or TCP transport. Specifically, when a single field (FullFormattedMessage) exceeds approximately 11,000 bytes, the message gets truncated to 64 characters in Graylog's interface causing the entire large field to be omitted. This truncation appears to be due to the $ShortMessage field, which has a character limit.Additionally, when the message is truncated, the $EventTime field, which is derived from a CSV column using parsedate(), does not parse correctly. It seems that when the message reaches its size limit, the $row_event is sent without executing any further processing. My current NXLog configuration is as follows:define INSTALLDIR /etc/nxlog define CERTDIR %INSTALLDIR%/cert define CONFDIR %INSTALLDIR%/nxlog.d define LOGDIR /var/log/nxlog define MYLOGFILE %LOGDIR%/nxlogCSVtest.log LogLevel INFO LogFile %MYLOGFILE% <Extension csv> Module xm_csv Fields IpAddress,UserAgent,Key,CreatedTime,UserName,FullFormattedMessage </Extension> <Extension gelf> Module xm_gelf </Extension> <Input file> Module im_file File '/home/user/test/logs_to_send.csv' <Exec> csv->parse_csv(); if ($UserName =~ /USER_A/) drop(); if (not defined($CreatedTime) or $CreatedTime=='' ) drop(); $EventTime = parsedate($CreatedTime); $CreatedTime = undef; # These fields are needed for Graylog $gl2_source_collector = '${sidecar.nodeId}'; $collector_node_id = '${sidecar.nodeName}'; &lt;/Exec&gt; </Input> <Output graylog_udp> Module om_udp Host 127.0.0.1 Port 5555 OutputType GELF_UDP </Output> <Route 1> Path file => graylog_udp </Route> The log file indicates an "Invalid CSV input" error for each row that is giving me the problem, but only displays the first 960 characters of the CSV rows in question.2024-02-13 16:59:08 ERROR Invalid CSV input: <the first 960 characters of the csv row> I am running NXLog CE on Ubuntu 22.04 with the Graylog sidecar, using package version nxlog-ce_3.2.2329_ubuntu22_amd64.On the data that desn't get the error it's working great, I know i'm hitting some limitation but i would like to know witch one and how can i change it.

When sending data to InsightIDR, you have to specify a unique port for each data source.  For example, on an AD DC, you need a unique port for security event logs, DNS logs, and DHCP logs.  As it currently appears, I would need a template or individual configuration on each system. To optimize/simplify this, is it possible to use FIELDS and PATTERNS in templates?  e.g. DC1_SecLog=<port 1000>, DC1_DNS=<port 1001>.  In the template reference a FIELD/PATTERN based on the agent info like hostname and/or tags?  Just looking for a way to minimize the number of templates I have to manage.

Learning how to build out templates and I see in the documentation, that you there should be an option for “MASTER” or “SUB” template types as described here:  https://docs.nxlog.co/manager/current/templates/index.htmlHowever, my new server (5.7.5935) does not have that option when creating a template.  Is there something that needs to be enabled or some set of actions before that becomes visible? 

Initiated a 30-day trial today to test what I had thought would be a fairly straightforward use case. The following config works fine to forward Windows events from the local machine via syslog, but when I add the File directive for im_msvistalog to the Input module section the events in the file are not forwarded over syslog. The file is correctly formatted and can be read via the event viewer. I also tested writing the contents of the file to a local json file as-per examples in the documentation, that worked fine as well. The file is publicly available at: https://github.com/sbousseaden/EVTX-ATTACK-SAMPLES/blob/master/Command%20and%20Control/DE_sysmon-3-rdp-tun.evtx Here are the contents of the config file: NoCache True define LOGHOST 192.168.xxx.xxx <Extension syslog> Module xm_syslog </Extension> <Input event_in> Module im_msvistalog File C:\Program Files\nxlog\logs\test_log.evtx Exec $Hostname = hostname(); </Input> <Output tcp_out> Module om_tcp Host %LOGHOST%:514 Exec to_syslog_snare(); </Output> <Route 1> Path event_in => tcp_out </Route>

Hi All,I am collecting and sending logs from a Windows Domain Controller (only security events). When I start the nxlog service, the logs are send in “real time”.

We are an MSSP that uses NXLog CE (3.2.2329) installed on a Windows Server acting as a Windows Event Collector (WEC) to forward events from the forwarded events channel to a syslog collector that sends everything to our SIEM.TL;DRCertain Windows Events send to our SIEM via NXLog are missing the <EventData> information whereas Event Viewer shows a complete event on the logsource host where NXLog is installed on. Longer versionThe current setup is:Domain Controllers forward their security events using Windows Event Forwarding to our WEC using a source initiated event subscription where the content format is set to ‘Events’ instead of the default ‘RenderedText’ (this change helped solve similar issues where data was missing from events send via NXLog).We've verified that these security events are present in the forwarded events channel on the WEC with a complete XML of the events.NXLog CE (3.2.2329) is installed on this WEC using the following nxlog.conf file:Panic Soft #NoFreeOnExit TRUE define ROOT C:\Program Files\nxlog define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf\nxlog.d define LOGDIR %ROOT%\data include %CONFDIR%\*.conf define LOGFILE %LOGDIR%\nxlog.log LogFile %LOGFILE% Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data <Extension _syslog> Module xm_syslog </Extension> <Extension _charconv> Module xm_charconv AutodetectCharsets iso8859-2, utf-8, utf-16, utf-32 </Extension> <Extension _exec> Module xm_exec </Extension> <Extension _fileop> Module xm_fileop # Check the size of our log file hourly, rotate if larger than 5MB &lt;Schedule&gt; Every 1 hour Exec if (file_exists('%LOGFILE%') and \ (file_size('%LOGFILE%') &gt;= 5M)) \ file_cycle('%LOGFILE%', 8); &lt;/Schedule&gt; # Rotate our log file every week on Sunday at midnight &lt;Schedule&gt; When @weekly Exec if file_exists('%LOGFILE%') file_cycle('%LOGFILE%', 8); &lt;/Schedule&gt; </Extension> <Input Security> Module im_msvistalog <QueryXML> <QueryList> <Query Id="0" Path="ForwardedEvents"> <Select Path="ForwardedEvents">*</Select> </Query> </QueryList> </QueryXML> </Input> <Output DL> Module om_tcp Host 123.123.123.123 Port 514 Exec to_syslog_snare(); </Output> <Route eventlog_to_DL> Path Security => DL </Route>NXLog sends logs to a syslog collector in the same networkThis syslog collector has SIEM agent software forwarding events to our SIEMIn our SIEM we can see all events coming in from the syslog collector, including NXLog Windows events, however some appear to be missing data found in the <EventData> field in the XML of the actual event.The event id's we're having issues with are Windows event ID 4662,4768 and 4776.Other event id's are coming in ‘complete’ as expected such as this event id 4672:<14>Dec 8 11:32:42 dc2.example.com MSWinEventLog 1 Security 5986982 Fri Dec 08 11:32:42 2023 4672 Microsoft-Windows-Security-Auditing N/A N/A Success Audit dc2.example.com Special Logon Special privileges assigned to new logon.
