func BlockNetwork 

func BlockNetwork(from string, to string)

The following helper functions can block/unblock network from source host to destination host by manipulating iptable rules. This function assumes it can ssh to the source host.

Caution: Recommend to input IP instead of hostnames. Using hostnames will cause iptables to do a DNS lookup to resolve the name to an IP address, which will slow down the test and cause it to fail if DNS is absent or broken.

Suggested usage pattern: 

func foo() {
	...

	...
}
