Even more DHCPD problems

[Nagy László Zsolt]

FreeBSD 10.2 RELEASE with dhcpd 5.

Here is a working /usr/local/etc/dhcpd.conf:

--------------------

authoritative;
allow unknown-clients;
use-host-decl-names on;
default-lease-time 1814400; # 21 days
max-lease-time 1814400; # 21 days

#db-time-format default;
#ddns-updates on;
#ddns-update-style interim;
#update-static-leases on;
#key rndc-key { algorithm hmac-md5; secret 12345678901234567890==; }

option domain-name "visznet";
option domain-name-servers 192.168.5.1;
option subnet-mask 255.255.255.0;

subnet 192.168.5.0 netmask 255.255.255.0 {
  range 192.168.5.100 192.168.5.199;
  option broadcast-address 192.168.5.0;
  option routers 192.168.5.1;
}


--------------------

This configuration does work. But if I try to activate any of the
commented lines, then I get errors like this:


Mar  5 13:36:01 gw dhcpd: /usr/local/etc/dhcpd.conf line 1: expecting a
parameter or declaration.
Mar  5 13:36:01 gw dhcpd: db-time-format
Mar  5 13:36:01 gw dhcpd: ^
Mar  5 13:36:01 gw dhcpd: Configuration file errors encountered
Mar  5 13:36:01 gw dhcpd: exiting.
Mar  5 13:36:01 gw gandalf: /usr/local/etc/rc.d/dhcpd: WARNING: failed
to start dhcpd

Exact package version: dhcpd-5.8.20151202. It seem that it does not know
many of the configuration parameters that I want.

*Most importantly:* how can I set it up to do ddns updates on the
nameserver?

Not so important questions:

  * Why can't I change the date format?
  * Why can't I store static leases in the leases file?
  * Why does it store epoch for all start/end leases instead of the good
    values?

Here is an example lease:

lease 192.168.5.115 {
        starts 4 1970/01/01 00:00:00 UTC;
        ends 4 1970/01/01 00:00:00 UTC;
        hardware ethernet 64:70:02:2b:6e:fb;
        uid 01:64:70:02:2b:6e:fb;
        client-hostname "Adam-PC";
}

The "starts" and "ends" values are always epoch, and when I start the
server I always get these messages:

Mar  5 13:45:12 gw dhcpd:                                   ^
Mar  5 13:45:12 gw dhcpd: /var/db/dhcpd.leases line 117: unparseable
time string
Mar  5 13:45:12 gw dhcpd:       ends 4 1970/01/01 00:00:00 UTC;
Mar  5 13:45:12 gw dhcpd:                                 ^
Mar  5 13:45:12 gw dhcpd: /var/db/dhcpd.leases line 123: unparseable
time string
Mar  5 13:45:12 gw dhcpd:       starts 4 1970/01/01 00:00:00 UTC;
Mar  5 13:45:12 gw dhcpd:                                   ^
Mar  5 13:45:12 gw dhcpd: /var/db/dhcpd.leases line 124: unparseable
time string
Mar  5 13:45:12 gw dhcpd:       ends 4 1970/01/01 00:00:00 UTC;


If I remove all dates from the lease file and restart the server, then
it starts up without warning, but writes out these epoch values
immediately. Next time I restart it is complaining about the unparseable
time strings again. Why is that?

Thanks,
