We have a network of 2 computers connected to a switch without a DHCP server. We have manually set set each of out IP addresses to 192.168.1.2 and 192.168.1.3 and everything works fine.
However we are using a 3rd party program (ROS to be exact), which can establish a connection using our manual IP addresses provided to it. However due to the way ROS works, most communications are done to the other computer's hostname, i.e. not the IP address, the actual name. Which obviously won't work.
We can't change the way ROS works, so how can we configure ubuntu to resolve the hostnames?
