DHCPD on the Linux Host Does Not Work After VMware Server
Installation

VMware!Server,!it!probably!was!configured!to!respond!to!DHCP!requests!from!clients!
on!any!network!interface!present!on!the!machine.!When!hostonly!networking!is!
configured,!an!additional!network!interface,!VMnet1,!is!marked!“up”!and!available
!for!
use,!and!dhcpd!might!notice!this.!
In!such!cases,!some!dhcpd!implementations!abort!if!their!configuration!files!do!not!
include!a!subnet!specification!for!the!interface!!even!if!dhcpd!is!not!supposed!to!
respond!to!messages!that!arrive!through!the!interface.!
The!best!solution!to!this!problem!is!
to!add!a!line!in!the!following!format!to!the!dhcpd!
configuration!file:
subnet <net>.0 netmask 255.255.255.0 {}
<net>!is!the!network!number!assigned!to!your!hostonly!network!!for!example,!
