Problem with DHCP leases status from snapshot 07-01-2007

Superman

I can confirm the same problem, exactly as stated.

Would you mind pasting parts of the dhcpd.leases file from /var/db/dhcpd/var/db/dhcpd.leases


# ls -l /var/dhcpd/var/db/dhcpd.leases
-rw-r--r--  1 root  _dhcp  466 Jan 15 21:27 /var/dhcpd/var/db/dhcpd.leases

and


# more /var/dhcpd/var/db/dhcpd.leases
# more /var/dhcpd/var/db/dhcpd.leases
# All times in this file are in UTC (GMT), not your local timezone.   This is
# not a bug, so please don't ask about it.   There is no portable way to

I would very much like to see what it looks like. I have a hunch, but I am not sure. I have rewritten this page because it was very slow and I think I might forgotten a case. But I need a working dhcpd.leases example for this.

Fixed in CVS

In case you did not catch all of the problem with the DHCP status page.
The "hostname" entries for the dynamically allocated IPs are missing from the Status page.

One of the entries in the DHCPD.leases file for the
1.0.1-SNAPSHOT-01-13-2007 built on Thu Jan 18 00:33:06 EST 2007

lease 192.168.1.179 {
starts 4 2007/01/18 07:09:10;
ends 4 2007/01/18 09:09:10;
tstp 4 2007/01/18 09:09:10;
binding state active;
next binding state free;
hardware ethernet 00:07:95:xx:xx:xx;
}

The /etc/hosts file does not contain a corresponding IP hostname entry.

if the dhcpd.leases file does not contain the client-hostname field I can not show it on the status page either.

I have a lot of dynamically connected clients here and those hostnames are shown normally.

Thanks databeestje,
It appears that WinXp DHCP Clients send the hostname to the DHCP server an it logs

lease 192.168.1.176 {
starts 4 2007/01/18 17:42:27;
ends 4 2007/01/18 19:42:27;
binding state active;
next binding state free;
hardware ethernet 00:0b:xx:xx:xx:xx;
uid "\xxx\xxx\xxx\xxx\xxxxx";
client-hostname "Calico";
}

whereas the Ubuntu 6.10 release dhcp3 client does not send its hostname to the pfsense DHCP server unless;

send host-name "ServerName"

is added to the /etc/dhcp3/dhclient.conf file.

"ServerName" must be specified manually since hostname does not pipe through.

is there a better way?

Please note that the "ServerName" does not appear in the Edit static mappings Hostname entry Box

There is a dhcp server knob to register dhcp hostnames in the DNS server.

But that still requires the client to send the hostname.

It's issue with Ubuntu, take it up with them. Knoppix and grml do send (generated) hostnames to the dhcp server.

Both
Register DHCP leases in DNS forwarder
Register DHCP static mappings in DNS forwarder
are enabled.

Version 1.0.1 transfered the hostname from the dynamic Hostname entry to the
Edit static mappings Hostname entry Box. Current version does not. If that is the way it is supposed to work ok.

Issues with Ubuntu were just a reference for others with the same problem.
Thanks again

I have corrected the issue of the hostname not being transfered to the edit static mappings hostname field. This fix should appear in a snapshot in the next few days.
