Chapter 7 Networking
An!alternative!solution!is!to!explicitly!state!the!set!of!network!interfaces!that!you!want!
dhcpd!to!listen!to!each!time!you!start!the!program.!For!example,!if!your!machine!has!one!
Ethernet!interface,!eth0,!then!each!time!you!start!dhcpd,!list!it!on!the!command!line:
dhcpd eth0
This!keeps!dhcpd!
from!probing!for!all!available!network!interfaces.!
If!the!above!solutions!do!not!work!for!your!DHCP!server!program,!then!it!likely!is!old.!
You!can!try!upgrading!to!a!more!current!version!such!as!the!DHCP!software!available!
from!the!ISC!Web!site!at!www.isc.org.
DHCP and Dynamic Domain Name Service (DDNS)
DHCP!can!be!used!to!hand!out!IP!addresses!as!well!as!other!information,!such!as!the!
identity!of!a!host!running!a!name!server!and!the!nearest!router!or!gateway.!The!DHCP!
server!in!VMware!Server!does!not!provide!a!means!to!dynamically!establish!a!
relationship!between!the!IP!address
!it!assigns!and!a!client’s!name!(that!is,!to!update!a!
DNS!server!using!DDNS).
If!you!want!to!use!names!to!communicate!with!other!virtual!machines,!you!must!either!
edit!the!DHCP!configuration!file!for!VMnet1!(/etc/vmware/vmnet1.conf)!or!use!IP!
addresses!that!are!statically!bound!to!a!host!name.
!Editing!the!DHCP!server!
configuration!file!requires!information!that!is!best!obtained!directly!from!the!DHCP!
server!documentation.!Consult!the!manual!pages!dhcpd(8)!and!dhcpd.conf(8).!
Setting Up a Second Bridged Network Interface on a Linux Host
If!your!host!computer!has!two!Ethernet!adapters!connected!to!two!different!networks,!
you!can!configure!your!virtual!machines!on!that!host!computer!to!bridge!to!both!
Ethernet!adapters.!That!way,!the!virtual!machines!can!access!either!or!both!physical!
networks.
When!you!install!VMware!Server!on!a!host!computer!with!
multiple!Ethernet!adapters,!
you!have!the!option!of!configuring!more!than!one!bridged!network.!You!can!also!
configure!additional!bridged!networks!at!any!time!by!rerunning!vmware-config.pl.
