Title:
  dhclient logs DHCPDISCOVER request (stdout and syslog) but doesn't
  send anything

Status in “isc-dhcp” package in Ubuntu:
  Confirmed

Bug description:
  I'm experiencing the problem that `dhclient -4 -w -v` logs messages in
  the form `DHCPDISCOVER on <interface> to 255.255.255.255 port 67
  interval 13 (xid=<xid>)`, e.g. `DHCPDISCOVER on wlan0 to
  255.255.255.255 port 67 interval 13 (xid=0x6d59d111)` both to console
  (stdout or stderr) and syslog, but wireshark shows that there're no
  requests sent over the network!! It works as expected, i.e. DHCP
  requests are actually sent over the network, if (as far as I
  experienced iff) I invoke `dhclient -r` before.

  experienced with isc-dhcp-client 4.2.4-7ubuntu12 on Ubuntu 14.04
