Edit file /usr/local/pkg/syslog-ng.inc - find

$conf .= "@version:3.3\n";

And replace it with

$conf .= "@version:3.5\n";

Save file, then go, and enable syslog-ng in its general settings - it will now successfully verify syntax and will generate /usr/local/etc/rc.d/syslog-ng.sh which is used to start service.

If package is update, service will continue to autostart successfully. It may refuse to save settings if you change something - in this case, go and repeat fix again…

This problem is in the package for some time already and it is sad that no one test this before releasing updates.
I might try and submit bug, but last time I tried, I could not for some reason...

thank you dgcom for your response.
now it's starts normally, but it does not log anything.
i wonder if there is a howto for syslog-ng configuration, for things like filters(to separate firewall logs from openvpn logs…).
:)

The documentation on syslog-ng contains all information how to configure destinations, sources and filters The syslog-ng Open Source Edition 3.5 Administrator Guide

As far as logging goes - what do you expect it to log? You have to configure clients to send syslog messages to it. It is not set to default port 514, because local syslog uses it…
I know, people use syslog-ng as an extension to default pfSense logging - to keep logs for longer, than circular log allows.

i want to use syslog-ng as an extension to default pfSense logging, i want log evreything logged by pfsense (firewall, system, dhcp…)
i tryed to use the documontation and some posts, i can save the sittings but no file generited for the logs (dhcpd.log , filter.log ...)

# This file is automatically generated by pfSense
# Do not edit manually !
@version:3.5
destination _DEFAULT { file("/var/syslog-ng/default.log"); };
destination dhcp { file("/var/syslog-ng/dhcpd.log"); };
destination firewall { file("/var/syslog-ng/filter.log"); };
destination message { file("/var/syslog-ng/messages.log"); };
destination ntpd { file("/var/syslog-ng/ntpd.log" ); };
filter f_alert { level (alert .. emerg); };
filter f_crit { level (crit .. emerg); };
filter f_emerg { level (emerg); };
filter f_err { level (err .. emerg); };
filter f_firewall { facility (local0); };
filter f_firewall-drop { facility (local0) and match(regexp value("drop")); };
filter f_firewall-pass { facility (local0) and match(regexp value("pass")); };
filter f_local7 { facility (local7); };
filter f_notice { level (notice .. emerg); };
filter f_warning { level (warning .. emerg); };
filter ntp {program (ntpd); };
log { source(_DEFAULT); destination(_DEFAULT); };
log { source(_DEFAULT); filter(f_local7); destination(dhcp); };
log { source(_DEFAULT); filter(f_firewall); destination(firewall); };
log { source(_DEFAULT); filter(f_firewall-drop); destination(firewall); };
log { source(_DEFAULT); filter(f_firewall-pass); destination(firewall); };
log { source(_DEFAULT); filter(ntp); destination(ntpd); };
source _DEFAULT { internal(); syslog(transport(udp) port(5140) ip(192.168.1.226) ip(127.0.0.1)); };

Did you configure pfSense to send logs to syslog-ng?
On Status: System logs: Settings page, enable remote logging - set it to log to your syslog-ng instance. Make sure that IP address corresponds to the interface selected in syslog-ng settings (I would use loopback if I there is no need to receive logs from external servers) and specify port for syslog-ng as well.

I do not know how good it would work for this - I do not use it like that.

[anass]

i use loopback address for remote syslog server and its work now thank you for helping me

i have one last question : now i can see logs in Syslog-ng Log Viewer , is there a way to reverse the view (newest first)

[dgcom]

That I do not know - I think it just shows files, written by syslog-ng and they are appended at the end.

thank you for your help  ;D
