The performance of Linux-based network solutions was one of the biggest issues in the past and that's why Intel started the Data Plane Development Kit (DPDK) project. The goal of the ODP environment is to provide a crossplatform framework for data plane applications. OpenFastPath (OFP) is another open source implementation of a high-performance TCP/IP stack which is helpful for network applications with a traditional Linux stack. In this tutorial, OFP will be installed on an Ubuntu 16.04 VM.

Thoughts on Monitoring file changes with Linux over the network
Author: stefbon • Tags: centos, debian, linux, networking, opensuse, shell, ubuntu • Comments: 1
Monitoring a directory for changes with Linux is possible through the well-known mechanism inotify. With inotify it's possible to set a watch on a directory, configure it to watch events on the contents, and you'll receive messages on a file descriptor when something happens. This works perfectly when the directory is on local storage, like a hard drive, SSD or a USB drive, But it is not sufficient when the directory is on a network filesystem when the storage is on another computer. Another user working in the same directory, connected via the same or another filesystem, can remove a file and the watch you've set on it will not get notified.
