rsp is a SSH client which implements SOCKS5 proxy feature of SSH protocol. Key feature of this implementation is use of multiple connections to overcome downsides of multiplexing many tunneled TCP connections in single SSH session. Multiple sessions are not limited with TCP window size of single connection and packet loss does not affect all tunneled connections
at once. In order to cut latency of connection establishment rsp maintains pool of steady connections, which replenished with configurable rate.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
