FTP Server
To create an FTP server program in Go, you need to create a few files: main.go for the main logic and optionally, a server.go file for the server functionality. Here is a step-by-step guide:
Step 1: Initialize the Go Module
First, create a new directory for your project and initialize the Go module.
mkdir ftpserver
cd ftpserver
go mod init github.com/username/ftpserver
Step 2: Create the server.go File
Create a server.go file to handle the FTP server functionality.
// server.go
package main
import (
"log"
"github.com/goftp/server"
)
// StartServer starts the FTP server on the specified port.
func StartServer(port string) error {
factory := &server.SimplePerm{
User: "test",
Pass: "1234",
}
driver, err := server.NewFileDriver("/tmp")
if err != nil {
return err
}
opts := &server.ServerOpts{
Factory: factory,
Port: port,
Driver: driver,
Auth: &server.SimpleAuth{Name: "test", Password: "1234"},
Perm: factory,
}
ftpServer := server.NewServer(opts)
return ftpServer.ListenAndServe()
}
Step 3: Create the main.go File
Create a main.go file to use the server functionality.
// main.go
package main
import (
"fmt"
"os"
)
func main() {
if len(os.Args) != 2 {
fmt.Println("Usage: ftpserver <port>")
os.Exit(1)
}
port := os.Args[1]
fmt.Printf("Starting FTP server on port %s...\n", port)
if err := StartServer(port); err != nil {
fmt.Printf("Server failed: %v\n", err)
os.Exit(1)
}
}
Step 4: Run the Program
Run the program using the go run command.
go run main.go 2121
This will start the FTP server on port 2121. You can connect to it using an FTP client with the username test and password 1234.
