Add to Cargo.toml:

mini-telnet = "0.1.2"

Example

/tmp/temp", timeout).await?; let output = telnet.execute("cat /tmp/temp", timeout).await?; assert_eq!(output, "test\n"); Ok(()) } "> 
use std::time::Duration;

use mini_telnet::Telnet;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let timeout = Duration::from_secs(5);
    let mut telnet = Telnet::connect("192.168.100.2:23", timeout).await?;
    telnet
        .set_username_prompt("login: ")
        .set_password_prompt("Password: ")
        .set_prompt("ubuntu@ubuntu:~$ ")
        .login("ubuntu", "ubuntu", timeout)
        .await?;

    println!("Telnet login Success.");

    telnet.execute("echo 'test' > /tmp/temp", timeout).await?;
    let output = telnet.execute("cat /tmp/temp", timeout).await?;
    assert_eq!(output, "test\n");
    Ok(())

  • Fix: Fixed to wait for multiple prompts

    Fix: Fixed to wait for multiple prompts

    Modified the prompt property of the Telnet structure to Vec to listen for multiple prompts during the connection. This is because the prompt changes when several commands are executed. I would appreciate it if you could check the modified part of the code.

  • Extraneous newlines in telnet server response

    Extraneous newlines in telnet server response

    Thanks for writing and releasing this crate. I'm using it to collect diagnostic data from my router and seem to be getting extra newlines in the response from the telnet server.

    When I telnet to my router using PuTTY and issue xdslctl info I get:

    xdslctl: ADSL driver and PHY status
Status: Showtime
Last Retrain Reason:    1
Last initialization procedure status:   0
Max:    Upstream rate = 12578 Kbps, Downstream rate = 60380 Kbps
Bearer: 0, Upstream rate = 12835 Kbps, Downstream rate = 59803 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

    but when I use mini-telnet and let response = telnet.execute("xdslctl info").await? and then println!("{}", response), I get:

    xdslctl: ADSL driver and PHY status

Status: Showtime

Last Retrain Reason:    1

Last initialization procedure status:   0

Max:    Upstream rate = 12578 Kbps, Downstream rate = 60276 Kbps

Bearer: 0, Upstream rate = 12835 Kbps, Downstream rate = 59803 Kbps

Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

    Could it be https://github.com/kolapapa/mini-telnet/blob/250f39d6bbae9ab2dc0cbe3b89639a9574ac0697/src/lib.rs#L255 that's introducing the extra newlines?
