Help with SSH Jumphost
I am trying to connect to an ssh server using another server as a jump host, but i have not been able to figure it out, wanted to see if i could get some hint or example to what i could be doing wrong
here is my full code
mod actor;
use russh::client as client_lib;
use std::sync::Arc;
use async_trait::async_trait;
use russh::{client, ChannelId};
use russh_keys::key::PublicKey;
#[actix_rt::main]
async fn main() {
let config = client_lib::Config::default();
let jumphost = "172.17.181.25";
let jumphost_port = 22;
let jumphost_username = "username";
let jumphost_password = "password";
let client = SshClient {
host: "172.17.181.27",
port: 22,
username: "username",
password: "password",
};
let custom_config = Arc::new(config);
let mut jumphost_session = client_lib::connect(
custom_config.clone(),
(jumphost, jumphost_port),
client.clone(),
)
.await
.unwrap();
if jumphost_session
.authenticate_password(jumphost_username, jumphost_password)
.await
.unwrap()
{
let channel_stream = jumphost_session
.channel_open_direct_tcpip(client.host, client.port as u32, "127.0.0.1", 0)
.await
.unwrap()
.into_stream();
let mut ts =
client_lib::connect_stream(custom_config.clone(), channel_stream, client.clone())
.await;
let mut target_session = ts.unwrap(); // <= Disconnect Error occurred hear
let is_authenticated = target_session
.authenticate_password(client.username, client.password)
.await
.unwrap();
if is_authenticated {
let mut channel = target_session.channel_open_session().await.unwrap();
channel
.request_pty(true, "xterm", 200, 200, 200, 200, &[])
.await
.unwrap();
channel.request_shell(true).await.unwrap();
channel.data(&b"ls -ls\n"[..]).await.unwrap();
}
// loop {
// if let Some(msg) = channel.wait().await {
// match msg {
// ChannelMsg::Eof => {
// println!("Server closed connection");
// std::process::exit(0);
// }
// ChannelMsg::Success => println!("Something was successfull"),
// ChannelMsg::Data { data } => println!("{:?}", data),

}
}
