This versatile plugin has many features and options, but this post will focus solely on syncing a single local folder to a remote folder. I recommend you peruse the README for more information.

Wireshark with Vagrant point-to-point (UDP tunnel) links

Vagrant supports three types of networks: public, private, and port-forwarding. The private network type has the option to use a UDP tunnel for a point-to-point link when using the vagrant-libvirt plugin. This connection type is ideal for links between virtual network devices. Refer to the following resources if you need more information: Pseudo-wires With Vagrant and Libvirt vagrant-libvirt Networks Vagrant Private Networks The only drawback with this type of connection is concerning packet sniffing....

SSH local port forwarding with remote GNS3 server

After opening the GNS3 client and starting nodes, we primarily access the remote virtual devices with a console connection. This console connection is either Telnet, VNC, or SPICE. A console connection covers our requirement for physical access to the virtual devices, but today most administrative tasks are carried out with a link to the network management interface . I define the GNS3 server as remote if the gns3server process is not running on the host operating system....

Convert AC3 audio to MP3 for XviD files with FFmpeg

I recently had an issue where I wanted to play a movie on one of my portable devices, but the file’s audio stream is encoded in the AC3 (Dolby Digital) format. But of course, the device doesn’t support AC3, so I need to convert it to a compatible format. Handbrake is my go-to tool for media file conversion, but it no longer supports output to XviD – specifically the AVI container....
