I set up my /etc/default/isc-dhcp-server and set eth0 in /etc/dhcp/dhcpd.conf
Why is the isc-dhcp Server not running? When I execute sudo service isc-dhcp-server status and got this:

Strange, strange, strange...
I get it working after i copied a default config file and edited our network into it.
Helpful for debugging are /usr/sbin/dhcpd -t and -f
Here is my config now:
default-lease-time 60;
max-lease-time 240;
authoriative;
option domain-name "psa-team06.informatik.tu-muenchen.de";
option domain-name-servers router.psa-team1.informatik.tu-muenchen.de;
authoriative;
subnet 192.168.6.0 netmask 255.255.255.0 { option broadcast-address 192.168.6.255; option routers 192.168.6.3; range 192.168.6.100 192.168.6.200;
}
host VM1 { hardware ethernet 08:00:27:24:41:79; fixed-address 192.168.6.3;
}This is not a defined configuration word:
interface eth1;I couldn't find it in man dhcpd.conf at least not for isc-dhcp-server. I have tried it in my VBox 16.04 server, dhcpd fails.
Not sure from where you got it, but may be you mistakenly meant: INTERFACES="eth1" from /etc/default/isc-dhcp-server which a configuration for the init service and it is used an command-line argument for dhcpd. Check pgrep -a dhcpd.
