  • Thoughts on Monitoring file changes with Linux over the network

    linux Author: stefbonTags: , , , , , , 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.

    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 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.
