Problem with the isc-dhcp-server

[fluit105]

PLEASE HELP!

I've been trying to launch dhcp-server but only this error come back:

Starting isc-dhcp-server (via systemctl): isc-dhcp-server.serviceJob for isc-dhcp-server.service failed because the control process exited with error code.
See "systemctl status isc-dhcp-server.service" and "journalctl -xe" for details.
 failed!

This is what systemctl status isc-dhcp-server.service says:

This is my dhcpd.conf file at /etc/dhcpd.conf :

authoritative;
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option domain-name "freewifi";
option domain-name-servers 192.168.1.1;
range 192.168.1.2 192.168.1.40;
}

If you use xCAT, the dhcpd.conf will have more than above pasted. did u use makedhcp command? try:

makedhcp -n
makedhpc -a

then check dhcp server again.

I'm afraid makedhcp is not recognized as a valid command, output: "bash: makedhcp: command not found". For the record I'm running Kali Linux.

[cxhong]

is your node has xcatd running?

lsxcatd -a
rpm -qa | grep -i xcat
