If DNS is correctly configured and working, what output do you get for your ping?
Does it say something like:-
If you see the IP address in the ping output, then you can be happy with DNS.
This could be a routing problem though. Can you publish the output from ifconfig -a and netstat -nr on your server? It may be that your ping gets to the server, but the server does not have a route to respond.

I am having a problem with a new server build that has got me completely baffled. This server has a private back end network so the way it is supposed to work is that the server thinks its ip address is 10.131.0.48 but the rest of the world knows it as 199.68.100.100 per DNS. It has to be this way... (2 Replies)

rping
RPING(1) librdmacm RPING(1)NAME
rping - RDMA CM connection and RDMA ping-pong test.
SYNOPSIS
rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
[-C message_count] [-S message_size]
rping -c [-v] [-V] [-d] -a address [-p port]
[-C message_count] [-S message_size]
DESCRIPTION
Establishes a reliable RDMA connection between two nodes using the librdmacm, optionally performs RDMA transfers between the nodes, then
disconnects.
OPTIONS -s Run as the server.
-c Run as the client.
-a address
On the server, specifies the network address to bind the connection to. On the client, specifies the server address to connect to.
-p Port number for listening server.
-v Display ping data.
-V Validate ping data.
-d Display debug information.
-C message_count
The number of messages to transfer over each connection. (default infinite)
-S message_size
The size of each message transferred, in bytes. (default 100)
-P Run the server in persistent mode. This allows multiple rping clients to connect to a single server instance. The server will run
until killed.
NOTES
Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions. See the
libibverbs README file for additional details.
