i installed dhcp3-server , now i want to start its service and it said : [FAIL] Starting ISC DHCP server: dhcpd[....] check syslog for diagnostics. ... failed! failed! i check ps aux | grep dhcp shows :

root 6178 0.0 0.0 9956 3708 ? S 23:06 0:00 /sbin/dhclient -d -4 -sf /usr/lib/NetworkManager/nm-dhcp-client.action -pf /var/run/dhclient-wlan0.pid -lf /var/lib/dhcp/dhclient-eee3fc61-32c1-4aa7-b189-94556369eac2-wlan0.lease -cf /var/run/nm-dhclient-wlan0.conf wlan0 root 6418 0.0 0.0 7764 860 pts/0 R+ 23:13 0:00 grep dhcp

dhcpd.conft is like default , before that i tried to implement a dhcp server on my at0 but i couldn't . if need a details just said . `i tried to remove it but :

[FAIL] Stopping ISC DHCP server: dhcpd failed!

What does the file /var/log/syslog show? That's where the diagnostic information will be.

If I had to guess, I'd say you don't have a static IP address configured for your interface that you have dhcpd set to run on. You need to add one in /etc/network/interfaces

  • i config static ip to my at0 ; and this is the last ten line of syslog : ` No subnet declaration for wlan0 ( Jun 25 23:21:20 bahram dhcpd: ** Ignoring requests on wlan0. If this is not what Jun 25 23:21:20 bahram dhcpd: you want, please write a subnet declaration Jun 25 23:21:20 bahram dhcpd: in your dhcpd.conf file for the network segment Jun 25 23:21:20 bahram dhcpd: to which interface wlan0 is attached. ** ` i think you right ; i clean my dhcp and my at0 and tried to start service dhcpd maybe you right, tnq – Bahram Jun 25 '14 at 19:05
