Java Question
Finding all aliases for a server via Java code
I have faced with inability to find all aliases for a domain name using InetAddress. Is there any way to grep them through Java in order to accomplish matching the results getting after the execution of
nslookup domain_name
Answer Source
It seems the only way to do this is to use native command line lookup though java Runtime class and further parse the cmd result string as in the below example
private static String execCmd(String cmd) {
java.util.Scanner s = s = new java.util.Scanner(Runtime.getRuntime().exec(cmd).getInputStream()).useDelimiter("\\A");
return s.hasNext() ? s.next() : StringUtils.EMPTY;
}
