dhcpd: create dhcpd user for dhcp dameon
This patch enables the functionality for dhcpd service to be started
with dhcp uid and gid.
Test steps:
Step 1: Assign ip to interface
ifconfig eth0 192.168.1.1
Step 2: Edit /etc/dhcp/dhcpd.conf:
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
subnet 192.168.1.0 netmask 255.255.255.0 {
option broadcast-address 192.168.1.255;
range 192.168.1.88 192.168.1.88;
option routers 192.168.1.0;
}
Step 3: Edit /etc/default/dhcp-server:
INTERFACES="eth0"
Step 4: Check uid and gid of running dhcpd process
$ ps -eo user:19,group:19,cmd | grep dhcpd
dhcp dhcp /usr/sbin/dhcpd eth0 -user dhcp -group dhcp
