Re: C# TCP Client to connect to MC4 via Hostname
|
I would also not rely on a ping for verification of a present device. There are environments that block pings, but only allow very specific service ports. ? Cheers,
Thorsten ? ? Did you add a DNS entry in your client's hosts file? This shows how on several different OSes. Also consider that if you are going to be creating a connection which is forced to secure (as in forces you to use TLS), there are some protocols which will automatically fail if there are issues with a certificate. The DNS entry not being verifiable can be one of those issues. Getting a certificate with a verified domain name such that your DNS name will be accepted is quite a chore. Then again, when I tried doing a very similar thing, I might have missed an obvious and easier path. ?

I created a test server on the MC4 at TCP port 9001.
The MC4 IP is 10.0.0.57 and the MC4 hostname is?MC4-00107FE73CAB
My Client class first checks if the IP address is pingable and then connects via IP Address
Everything is working great except now I am trying to ping test and connect with the HostName of the MC4 and nothing works.
string hostName = "MC4-00107FE73CAB"
_client = new TcpClient();
_client.Connect(hostName, port);
Any help would be appreciated
Thanks
