autodiscovery

I am trying to implement server auto discovery so that clients will be able to see a list of servers available to connect to. I would like to auto discover servers even if they are in different subnets. I have read that windows does not respond to broadcast ping, but is it possible to make all these servers to join a multicast group and use multicast ping on the group to see what servers are up? Thanks Try Zero configuration networking (Zeroconf) . Note multiple LAN segments requires routers to be configured to route multicast traffic, they do not by default. Similarly IGMP enabled switches

I have to network devices: 1. Server (variable IP) that needs to receive a String for further stuff (e.g. Socket 9999). This server has also another socket (e.g. 8888) where it sends it's device name on pairing. 2. Client (variable IP) that does NOT know the IP of the server but wants to send him the string. On a IP C-network I could iterate through the last octet (0..255) and check if Socket 8888 transmits something. But on A and B networks I have no chance. Is there any other solution for this? (I could iterate through all four octets but that wouldn't be an elegant solution). Thank you! The

We use the following function to auto detect if we are on a machine internally or on a live server and then choose the appropriate configs for various components: function devIsLocal(){ $res=false; $http_host=$_SERVER['HTTP_HOST']; if($http_host=='localhost')$res=true; if($http_host=='127.0.0.1')$res=true; if(substr($http_host,-4)=='.lan')$res=true; if(strpos($http_host, '.')===false)$res=true; return($res); } As you can see it only relies on the HTTP_HOST value. Of course, if you use some sort of virtual host locally like example.com then the function will be tricked. Are there any other ways

I'm starting with an address for an Exchange 2007 server: user@domain.exchangeserver.org And I attempted to send an autodiscover request, as documented at MSDN . I attempted to use the generic autodiscover address documented at the TechNet White Paper . So, using curl on PHP, I sent the following request: <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006"> <Request> <EMailAddress>user@domain.exchangeserver.org</EMailAddress> <AcceptableResponseSchema> http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a <

Using py.test, two tests called the same in different directory causes py.test to fail. Why is that? How can I change this without renaming all the tests?
