Package nutsak (Network Utility Swiss-Army Knife) will provide a means of tunneling traffic between two endpoints. Here is sample code to create a Pair: This will create a TCP listener on port 4444 that forks each new connection. Any received data will be written to STDOUT. The Network Utilties (NUts) are created from seeds. Below are the supported SEED TYPES along with their documentation: FILE:addr[,mode=(append|read|write)] This seed takes an address that is an absolute or relative filename. This seed is used to read or write a file on disk. The default mode is read. STDIO: Aliases: -, STDIN, STDOUT This seed takes no address or options. It can be used to read from stdin or write to stdout. TCP:addr This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to make an outgoing TCP connection. TCP-LISTEN:addr[,fork] Aliases: TCP-L This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to listen on the provided TCP address. The fork option causes the TCP listener to accept multiple connections in parallel. TLS:addr[,ca=PATH,cert=PATH,key=PATH,verify] This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to make an outgoing TLS connection. The ca, cert, and key options take a filepath (DER or PEM formatted). The verify option determines if the the server-side CA should be verified. The cert and key options must be used together. If verify is specified, a ca must also be specified. TLS-LISTEN:addr[,ca=PATH,cert=PATH,fork,key=PATH,verify] Aliases: TLS-L This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to listen on the provided TCP address. The ca, cert, and key options take a filepath (DER or PEM formatted). The fork option causes the TLS listener to accept multiple connections in parallel. The verify option determines if the client-side certificate should be verified. The cert and key options are mandatory. If verify is specified, a ca must also be specified. UDP:addr This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to make an outgoing UDP connection. UDP-LISTEN:addr Aliases: UDP-L This seed takes an address of the form [IP:]PORT. The IP is optional and essentially defaults to localhost, or more specifically, 0.0.0.0 or [::]. This seed is used to listen on the provided UDP address.
