sam-forwarder
Forward a local port to i2p over the SAM API.
building
Just:
make deps build
and it will be in the folder ./bin/
usage
./bin/ephsite -host=host -port=port
So, to serve an eepSite version of a local service on port 8080 -
./bin/ephsite -host=127.0.0.1 -port=8080
Quick-And-Dirty i2p-enabled golang web applications
Normal web applications can easily add the ability to serve itself over i2p by importing and configuring this forwarding doodad. Wherever it takes the argument for the web server's listening host and/or port, pass that same host and/or port to a new instance of the "SAMForwarder" and then run the "Serve" function of the SAMForwarder as a gorouting. This simply forwards the running service to the i2p network, it doesn't do any filtering, and if your application establishes out-of-band connections, those may escape. Also, if your application is listening on all addresses, it will be visible from the local network.
Here's a simple example with a simple static file server:
package main package main
import ( import (
"flag" "flag"
"log" "log"
"net/http" "net/http"
) )
> import "github.com/eyedeekay/sam-forwarder"
>
func main() { func main() {
port := flag.String("p", "8100", "port to serve on") port := flag.String("p", "8100", "port to serve on")
directory := flag.String("d", ".", "the directory of static file to host") directory := flag.String("d", ".", "the directory of static file to host")
flag.Parse() flag.Parse()
>
> forwarder, err := samforwarder.NewSAMForwarderFromOptions(
> samforwarder.SetHost("127.0.0.1"),
> samforwarder.SetPort(*port),
> samforwarder.SetSAMHost("127.0.0.1"),
> samforwarder.SetSAMPort("7656"),
> samforwarder.SetName("staticfiles"),
> )
> if err != nil {
> log.Fatal(err.Error())
> }
> go forwarder.Serve()
http.Handle("/", http.FileServer(http.Dir(*directory))) http.Handle("/", http.FileServer(http.Dir(*directory)))
log.Printf("Serving %s on HTTP port: %s\n", *directory, *port) log.Printf("Serving %s on HTTP port: %s\n", *directory, *port)
log.Fatal(http.ListenAndServe("127.0.0.1:"+*port, nil)) log.Fatal(http.ListenAndServe("127.0.0.1:"+*port, nil))
} }
This tiny file server taken from here and used for this example
