For development, VMWare can be used to easily simulate a hotspot user. The following illustrates how to configure a Linux system (Ubuntu in this case) running CoovaChilli and Windows Vista running inside VMWare as the client.
Select a vmnet interface to use. It should be one not already active in an ifconfig.
# ifconfig vmnet0 vmnet0: error fetching interface information: Device not foundBut, the device itself should be there:
# ls -l /dev/vmnet0 crw------- 1 root root 119, 0 2008-06-24 06:39 /dev/vmnet0Bring up the interface:
# vmnet-netifup /dev/vmnet0 vmnet0 & # ifconfig vmnet0 0.0.0.0 up
Your chilli should then be configured to use the vmnet interface. You can do this using the HS_LANIF setting in etc/chilli/config or the dhcpif option directly in the chilli.conf. Here is a sample etc/chilli/config style configuration:
HS_LANIF=vmnet0 HS_NETWORK=192.168.90.0 HS_NETMASK=255.255.255.0 HS_UAMLISTEN=192.168.90.1 HS_UAMPORT=3990 HS_DNS1=192.168.90.1Of course, the network should be one that your system is not already using.
Assuming your system is not already configured to be a router, you may need the following iptables configuration to provide NAT for outbound traffic:
# iptables -I POSTROUTING -t nat -o eth0 -j MASQUERADEwhere eth0 is the WAN (or Internet) interface that has the default route. The chilli init script will do it for you, but also ensure the kernel will forward packets:
# echo 1 > /proc/sys/net/ipv4/ip_forwardIn the chilli config above, we set the DNS server to that of the local interface. So, your system should be running a DNS server. In ubuntu, it's just a matter of:
# apt-get install dnsmasq
Now, configure your vmware virtual machine to use the above configured interface, as shown here.
Launch a browser in the vmware guest, and it is just like being at a hotspot.
