Warren, >Now that we’ve dispensed with Nagle, let’s get down to the actual issue. Correct. I was trying to find something... Agreed that is on the sending side - I am on the receiving side. Are there other options that this single byte CR over socket is not getting seen by my application. tshark shows its been received, I have tried to skip my select() call and just call recv() with nonblocking direct - the byte is not seen. Very odd. Jerry _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
