I am trying a simple client-server example between two machines (using socket programming). When I run the client, I get the error: "No route to host".
Now, here is what I observed.
I can ssh to the server from the client, but cannot telnet.
I can ping to the server from the client but cannot traceroute. Well actually it runs but I get the error: !X which I understand means that the admin is prohibited such communication.
So does that mean that:
1) I will be able to do only secure communication beteen the two machines?
2) BSD socket API is by default unsecure?
3) What is the best secure socket API to use?
Thanks a bunch in advance.
