curvetun - lightweight curve25519-based multiuser IP tunnel SYNOPSIS
curvetun [-d|--dev <tun>][-x|--export][-C|--dumpc][-S|--dumps] [-k|--keygen][-c|--client [<alias>]][-s|--server][-N|--no-logging] [-p|--port <num>][-t|--stun <server>][-4|--ipv4][-6|--ipv6] [-v|--version][-h|--help] DESCRIPTION
curvetun embeds a client and a server to build and manage multiuser IP tunnels using Elliptic Curve Cryptography (ECC) EXAMPLES
curvetun --keygen Generate public/private keypair. This needs to be done before to get things started. curvetun --export Export public data to remote servers curvetun --server -4 -u -N --port 6666 --stun Start a UDP IPv4 curvetun server on port 6666. Use as STUN server. curvetun --client=ethz Start curvetun client using the profile called 'ethz' OPTIONS
-k|--keygen Generate public/private keypair. -x|--export Export your public data for remote servers. -C|--dumpc Dump parsed clients. -S|--dumps Dump parsed servers. -D|--nofork Do not daemonize. -d|--dev <tun> Networking tunnel device, e.g. tun0. -c|--client [<alias>] Client mode, server alias optional. -s|--server Server mode. -N|--no-logging Disable server logging (for better anonymity). -p|--port <num> Port number (mandatory). -t|--stun <server> Show public IP/Port mapping via STUN. -u|--udp Use UDP as carrier instead of TCP. -4|--ipv4 Tunnel devices are IPv4. -6|--ipv6 Tunnel devices are IPv6. -v|--version Print version. -h|--help Print help text and lists all options.

bubbros-server - the bub-n-bros server. SYNOPSIS
bubbros-server [ level-file.bin ] [options] DESCRIPTION
bubbros-server starts an http server that acts as a control panel for the server. The server listens on port 8000 by default. The url for the control panel is http://server:port/0xN where 0xN is a random hex number (acts as minimal protection). This url is printed when the server starts. You can start and view games and kill the server from this panel. The control panel also allows you to type in the address of a server to connect to, the script will then open a client to that server. The http server also servers java applet clients for those players who wish to use one. When a game is started the script opens a port for the game server. This port can then be connected to by a client. Clients autodetect servers running on the local network with UDP ping on port 8056. Connection forming The client forms a tcp connection to the server. Or, when using the metaserver, the server forms a connection to the client. If this fails, the client and server try a simultaneous SYN connect. This sometimes works if the server and client are behind firewalls. The server then tries to transmit the data over udp. If it gets no response from the client it will fall back to the existing tcp connection. OPTIONS
-b N, --begin N, --start N Start at board (level) number N. The default is 1. See also the -s option. -h, --help Display help. -i, --infinite Restart the server at the end of the game. Normally the server quits after a certain period of inactivity. This is useful when used with the -m option to make a public server that is available for a long time. -l N, --lives N Limit number of lives to N. If this option is not specified the number of lives will be infinite. -m, --metaserver Register server with the Metaserver (currently) at This makes your server visible to everybody, and also facil- itates joining through a fascistic firewall. --port TYPE=N Sets default listening ports. If type is LISTEN , sets the game server port to N. The game server port is chosen randomly by default. If the type is HTTP , sets the http server port to N. The http server port defaults to 8000. Another port will be chosen if none was specified and 8000 is already in use. The server also listens to UDP ping on port 8056. -s N, --step N Increase board number with N when a board is completed. Defaults to 1. see also the -b option. OUTPUT
The server outputs helpful debug information concerning the http and game servers. SEE ALSO
