ssh-agent is a program to hold in memory the private keys used by SSH for public-key authentication. When the agent is running, ssh forwards to it the signature requests from the server. The agent performs the private key operations and returns the results to ssh. It is useful if you keep your private keys encrypted on disk and you don’t want to type the password at each connection. Keeping the agent secure is critical: someone able to communicate with the agent can authenticate on your behalf on remote servers.
Katran is a C++ library and BPF program to build high-performance layer 4 load balancing forwarding plane. Katran leverages XDP infrastructure from the kernel to provide an in-kernel facility for fast packet's processing.
Katran's key features:
1) Blazing fast (especially w/ XDP in driver mode).
2) Performance scaling linearly with a number of NIC's RX queues.
3) RSS friendly encapsulation.
Snabb (formerly "Snabb Switch") is a simple and fast packet networking toolkit.
