Empty dhcpd.log

[savago]

8.1-RELEASE-p1 FreeBSD 8.1-RELEASE-p1 #1: Thu Nov 18 23:20:46 EST 2010     sullrich@FreeBSD_8.0_pfSense_2.0-snaps.pfsense.org:/usr/obj.pfSense/usr/pfSensesrc/src/sys/pfSense_SMP.8  i386

Dhcpd don't log in dhcpd.log/system.log client request.

[wallabybob]

Probably dhcpd doesn't see the request (blocked by firewall? check firewall log; connectivity problem?)

Packet capture can be useful to verify DHCP request is getting to your pfSense system.

Please clarify "empty dhcpd.log". Does that mean it contains nothing at all OR that it doesn't contain any DHCP request information?

How are you examining the dhcpd log? web GUI? Shell command? If shell command, what command?

Looks like a bug. That interaction should have produced a couple of dhcpd log entries.

[_igor_]

I can confirm that. DHCP-log is empty. Seen with Web-IF.

[Macom2007]

Same here ….

[wallabybob]

igor and Macom2007 : What pfSense builds are you using?

[mxx]

mine's empty too (web interface system log/ dhcpd log). But I'm still on Nov 21 02:37:38 EST 2010 .
Will upgrade tomorrow.

[_igor_]

At the moment its Nov, 22 i386 release. I'm updating daily. Its now a while but i didn't look every day on it. Hope that helps.

[jimp]

Empty here too, though the config file has the proper syslog facility set, and syslog.conf is looking for the right syslog facility as well.
