  • Thoughts on Monitoring file changes with Linux over the network

    linux Author: stefbonTags: , , , , , , Comments: 0

    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.

    Network simulators are tools used to simulate discrete events in a network and which helps to predict the behaviours of a computer network.

Administrators can then customize the simulator to suit their needs. Network simulators typically come with support for the most popular protocols and networks in use today, such as WLAN,UDP,TCP,IP, WAN, etc.

  • Bluetooth PAND (Personal Area Network) Howto For Debian Etch

    Author: zdenekboureshTags: , Comments: 10

    Bluetooth PAND (Personal Area Network) Howto For Debian Etch I wanted to access the internet over bluetooth instead of GPRS/3G network from my mobile phone (SE K800i). After a lot of searching I couldn't find a clear explanation as how to accomplish this.

After another fruitless search, I managed to figure out how to make a bluetooth internet profile instead of GPRS or 3G on the phone. Since I work in Linux most of the time, I decided to have a go and do it with Debian, my workstation's main OS. After spending a few hours, I had it working using the steps below.
