This guide demonstrates the most common aspects of libvirt networking, whether running virtual machines (VMs) on a dedicated server or within a home lab.

How to choose a network type

On a dedicated server — where VMs often need to be publicly accessible — a Bridged network is ideal and allows each VM to bind to its own public IPv4 and IPv6 addresses. If bridging is not possible, create a Routed network. If the server has limited public IPv4 addresses, a NAT-based network that forwards incoming connections may be the only option.

Inside an intranet or home lab, a NAT-based network gives VMs outbound network access. If VMs are running services that must be accessible from other systems on the LAN, create a Bridged network (for an Ethernet connected libvirt host) or a Routed network (for a wirelessly connected libvirt host).

If you want to prevent libvirt from automatically inserting iptables rules, create a Bridged network, Custom routed network, or Custom NAT-based network.

This repo contains (almost) transparent matrix gateway.
Following features are implemented:

• Sending and receiving emails, both plaintext and HTML.
  Bridge will dynamically create rooms and invite matrix users/mail puppets when new message appears, see 'Usage' section.
• Turning matrix room into something like mailing list.
• Sending and receiving attachments (looks ugly, see end of file).

confluence-vim

A vim plugin for taking notes in markdown and storing them in a confluence wiki.

It's really simple, I hope you like it.

You need to install html2text, markdown, and requests, and your vim needs to be compiled with python support. You also need to write your credentials in your .netrc file.

Jolokia is remote JMX with JSON over HTTP.
It is fast, simple, polyglot and has unique features. It's JMX on Capsaicin.

Jolokia is a JMX-HTTP bridge giving an alternative to JSR-160 connectors. It is an agent based approach with support for many platforms. In addition to basic JMX operations it enhances JMX remoting with unique features like bulk requests and fine grained security policies.

The installation of the Openvswitch on Ubuntu brings an automatic integration into the boot sequence. When Ubuntu is booted, the Openvswitch is also started. Any bridge or port, which has been defined in previous sessions, is restored.
BUT: No L3 interfaces are set up, junk interfaces, which have been defined in previous sessions, are restored.

Bridge relays (or "bridges" for short) are Tor relays that aren't listed in the main Tor directory. Since there is no complete public list of them, even if your ISP is filtering connections to all the known Tor relays, they probably won't be able to block all the bridges. If you suspect your access to the Tor network is being blocked, you may want to use the bridge feature of Tor.
