dhcpcd not running - Raspberry Pi Forums

i started raspberry pi recently. trying set wireless connection rpi , internet. have wifi adapter , right module it.

have done changes
/etc/network/interfaces , /etc/wpa_supplicant/wpa_supplicant.conf

interfaces this

code: select all

auto lo  iface lo inet loopback iface eth0 inet dhcp  allow-hotplug wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf  iface default inet dhcp  

, wpa_supplicant.conf

code: select all

ctrl_interface=dir=/var/run/wpa_supplicant group=netdev update_config=1  network={      ssid="wifi name here"      psk="wifi password here"  }  

think did wrong here cause dhcpcd not running.
run code

code: select all

sudo dhcppcd 

got error message. why?

code: select all

[fail] usage: /etc/init.d/dhcpcd {start|stop|restart|try-restart|force-reload|status} ... failed!
