For those that run VMware Fusion, the “\/Library\/Preferences\/VMware Fusion”\u00a0<\/em> directory on the Mac is a wealth of information.<\/p>\n

The license-fusion… files have your license keys as well as other information in them. But today, the jewel for me is the networking<\/strong> file:<\/p>\n

$ cat networking

\nanswer VNET_1_DHCP yes
\nanswer VNET_1_DHCP_CFG_HASH E08B... ...D0D8
\nanswer VNET_1_HOSTONLY_NETMASK 255.255.255.0

\nanswer VNET_8_HOSTONLY_NETMASK 255.255.255.0
\nanswer VNET_8_HOSTONLY_SUBNET 10.c.d.0
\nanswer VNET_8_NAT yes
\nanswer VNET_8_VIRTUAL_ADAPTER yes
\n...
\n<\/code>
\nThis file defines the networks that your host-only<\/em> and nat<\/em> network adapters use. VMware appears smart enough to avoid network collisions e.g. using 192.168.1.0\/255 for the NAT adapter at vmnet8 when that’s also the network configured on your home router.<\/p>\n

According to this article (VMware login required),<\/em><\/a> simply editing this file and restarting VMware Fusion’s networking component should change the dhcp setting that your machine uses. Any skilled system or network administrator should be able to get their hands around that.<\/p>\n

Finally, the lines that specify DHCP hashes appear to be the mechanism that VMware uses to detect changes in the networking file. If you dig deeper, there’s a directory for vmnet1.<\/p>\n

This is just a standard dhcpd.conf file as you would see if you ran isc-dhcpd. The interesting thing is that the hash is what you get if you do this:
\n$ sed -ne '\/VMNET DHCP.*Start\/,\/VMNET DHCP.*End\/ p' vmnet1\/dhcpd.conf | shasum
