Installation - problems to get started

[tomnick]

Hi, I installed everything so far and getting the following errors:

/home/pi/poisontap/pi_startup.sh: 8: cd: can't cd to /sys/kernel/config/usb_gadget/ ln: failed to create symbolic link ‘configs/c.1/acm.usb0’: File exists ln: failed to create symbolic link ‘configs/c.1/ecm.usb0’: File exists ls: cannot access /sys/class/udc: No such file or directory Ignoring unknown interface usb0=usb0. usb0: ERROR while getting interface flags: No such device SIOCADDRT: No such device [....] Starting isc-dhcp-server (via systemctl): isc-dhcp-server.serviceJob for isc-dhcp-server.service failed. See 'systemctl status isc-dhcp-server.service' and 'journalctl -xn' for details. failed! net.ipv4.ip_forward = 1

systemctl status isc-dhcp-server.service:

isc-dhcp-server.service - LSB: DHCP server Loaded: loaded (/etc/init.d/isc-dhcp-server) Active: failed (Result: exit-code) since Fri 2016-11-18 16:21:50 UTC; 22s ago Process: 3556 ExecStart=/etc/init.d/isc-dhcp-server start (code=exited, status=1/FAILURE)

Any idea what could be wrong?
