Dhcpd cannot assign DHCP Static Mappings for client after I upgrade pfsense
-
I have upgraded pfsense to 2.2.3-RELEASE (amd64) . I am using DHCP static mapping to assign IP for end user. Existing end user get IP from dhcpd without problem but new end user cannot get IP. There is a line in dhcpd log:
dhcpd: DHCPDISCOVER from xx:xx:xx:xx:xx:xx via igb1: network 192.168.32.0/20: no free leases
Follow the log, I guess Dhcpd don't have free lease to assign IP but my IP range has many free IPs. I go to /var/dhcpd/var/db.
ls -l -rw-r--r-- 1 root _dhcp 59564 Jul 25 20:38 dhcpd.leases -rw-r--r-- 1 dhcpd _dhcp 62306 Jul 25 20:38 dhcpd.leases~ -rw-rw---- 1 dhcpd _dhcp 0 Sep 30 2014 dhcpd6.leases
My dhcpd don't have write permission on dhcpd.leases
I do it:chown dhcpd:_dhcp dhcpd.leases
It works !
But when I restart dhcpd service, my change went out. I don't want to chown after I restart dhcpd.
There is other problem. When my pfsense server is rebooted by loss power, dhcpd is impossible to start.
-rw-r--r-- 1 2051 65 59564 Jul 25 20:38 dhcpd.leases -rw-r--r-- 1 2051 65 62306 Jul 25 20:38 dhcpd.leases~ -rw-rw---- 1 2051 2051 0 Sep 30 2014 dhcpd6.leases
I absolutely lose all group and user for dhcpd. I don't have any ideas for the reasons.
My question is how do I make Dhcpd work ?
P/S: I remember my dhcp group name is dhcpd. I don't know why it is _dhcp.
This is the command that dhcpd is using to start:/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid igb3 igb1 igb6 igb7 igb2_vlan5 igb2_vlan45 igb2_vlan6 igb2_vlan69 igb2_vlan67 igb2_vlan20

Stop messing with the permissions, they are just fine. You even posted that:
-user dhcpd -group _dhcp
which matches both the user and group permissions.

Get latest 2.2.4 snapshot. Known issue with filesystem corruption.

File permission is not fine
ls -l -rw-r--r-- 1 root _dhcp 59564 Jul 25 20:38 dhcpd.leases -rw-r--r-- 1 dhcpd _dhcp 62306 Jul 25 20:38 dhcpd.leases~ -rw-rw---- 1 dhcpd _dhcp 0 Sep 30 2014 dhcpd6.leases
My dhcpd don't have write permission on dhcpd.leases
I do it:
chown dhcpd:_dhcp dhcpd.leases
It works ! New end users are possible to get IP from DHCP
But when I restart dhcpd service, my change went out. I don't want to chown after I restart dhcpd.
I recreate groupname _dhcp and username dhcpd for dhcpd service but incorrect permission make DHCP no free lease.
It always changes to root: _dhcp after I restart dhcpd service. -
Dude. You have a corrupt filesystem with missing/screwed /etc/group. Stop "fixing" permissions, do a clean 2.2.4 install and restore config.
