golang SSH server get messages












-1














I want to make and ssh server, but i cant find a working way of getting messages from client.
Here is a server code that i got (i was trying different ways):



package main

import (
"github.com/gliderlabs/ssh"
"golang.org/x/crypto/ssh/terminal"
"io"
"log"
)

func main() {
ssh.Handle(func(s ssh.Session) {
io.WriteString(s, "Connectedn")
var b byte
s.Read(b)
term := terminal.NewTerminal(s, "> ")
line, err := term.ReadLine()
line2 := string(b)
log.Println(line)
if err != nil {
}
response := line
log.Println(line)
log.Println(line2)
if response != "" {
term.Write(append(byte(response), 'n'))
}
log.Println("terminal closed")
})

log.Fatal(ssh.ListenAndServe(":2222", nil))
}


and i send message in client like that:



b, err := session.CombinedOutput(text)


i just dont get any message in server
client gets only Connected and "> "



added client code:



package main

import (
"bufio"
"flag"
"fmt"
"golang.org/x/crypto/ssh"
"os"
)

var (
user = flag.String("u", "user", "User name")
pass = flag.String("pass", "1234", "User password")
host = flag.String("h", "localhost", "Host")
port = flag.Int("p", 2222, "Port")
)


func main() {
flag.Parse()
reader := bufio.NewReader(os.Stdin)

config := &ssh.ClientConfig{
User: *user,
Auth: ssh.AuthMethod{
ssh.Password(*pass),
},
}
config.HostKeyCallback = ssh.InsecureIgnoreHostKey()

addr := fmt.Sprintf("%s:%d", *host, *port)
client, err := ssh.Dial("tcp", addr, config)
if err != nil {
panic(err)
}

session, err := client.NewSession()
if err != nil {
panic(err)
}
defer session.Close()
text, err := reader.ReadString('n')
text = text[:len(text)-1]
if err != nil {
fmt.Println("Некорректный ввод", err)
}
b, err := session.CombinedOutput(text)
if err != nil {
panic(err)
}
fmt.Print(string(b))

}

  • Have you debugged your code to see what it is doing? You can review what others have done, as well: github.com/gliderlabs/ssh

  • I added a client code. This client is working with other servers, and get answers from them, so the problem in server, i just can't find any info how to manage it. What i've found worked with older version of go ssh package, but it doesnt support now
