Installation

# Install Plasma package to support color configuration
sudo apt-get install plasma-workspace plasma-desktop

# Install Kdenlive
sudo apt-get install kdenlive

Prerequisites

Ostinato v0.9 has the following dependencies:

QT 4.3+ (but not Qt5.x)
Protocol Buffers 2.3+ (bug not 3.x)
libpcap

Install Prerequisites

Installation

Install tacacs+ server:

sudo apt-get install tacacs+

Install tacacs+ client:

Create the RSA Key Pair

ssh-keygen -t rsa

Copy the public key to a server

ssh-copy-id user@server

Encoding

Encode video for uploading to Youtube/Vimeo. The output should be a similar quality as the input and will hopefully be a more manageable size.

ffmpeg -i input.avi -c:v libx264 -preset slow -crf 18 -c:a copy -pix_fmt yuv420p output.mkv

Same as above, but also re-encode the audio using AAC instead of stream copying it:

ffmpeg -i input.mov -c:v libx264 -preset slow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p output.mkv

Just using this one-music-note command

sudo socat TCP4-LISTEN:12345,fork TCP4:192.168.1.2:56789

Or with UDP port:

sudo socat UDP-LISTEN:161,fork UDP:10.72.211.141:161

Instructions

sysctl net.ipv4.ip_forward=1
iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 12345 -j DNAT --to-destination 192.168.1.2:56789
iptables -t nat -A POSTROUTING -j MASQUERADE
