Kilo connects nodes in a cluster by providing an encrypted layer 3 network that can span across data centers and public clouds. By allowing pools of nodes in different locations to communicate securely, Kilo enables the operation of multi-cloud clusters. Kilo's design allows clients to VPN to a cluster in order to securely access services running on the cluster. In addition to creating multi-cloud clusters, Kilo enables the creation of multi-cluster services, i.e. services that span across different Kubernetes clusters.
Tunnel is fast and secure client/server package that enables proxying public connections to your local machine over a tunnel connection from the local machine to the public server. It enables you to share your localhost when you dont't have a public IP or you are hidden by a firewall.
Streisand sets up a new server running L2TP/IPsec, OpenConnect, OpenSSH, OpenVPN, Shadowsocks, sslh, Stunnel, a Tor bridge, and WireGuard. It also generates custom instructions for all of these services. At the end of the run you are given an HTML file with instructions that can be shared with friends, family members, and fellow activists.
Algo VPN is a set of Ansible scripts that simplifies the setup of a personal IPSEC VPN. It contains the most secure defaults available, works with common cloud providers, and does not require client software on most devices.
Chisel is a fast TCP tunnel, transported over HTTP. Single executable including both client and server. Written in Go (Golang). Chisel is mainly useful for passing through firewalls, though it can also be used to provide a secure endpoint into your network. Chisel is very similar to crowbar though achieves much higher performance.
A friend once told me that his university has an HTTP(S)-only proxy, and thus he is unable to SSH to hosts outside. 5 hours of intensive coding later using code borrowed from my course assignment, here’s HOP.
HOP is a tool meant to tunnel any sort of traffic over a standard HTTP channel.
