class Ssh

Overview

This is a network library of SSH.

Using `net.Ssh`

This library will be available with using below.

using net.Ssh;

Conttructor

The destination host address is specified in the constructor’s argument.

var ssh = new Net.Ssh("127.0.0.1");

SSH login should be done after open(). The example below is a style in general.

var ssh = new Net.Ssh("Target IP address");
ssh.open { &(con)
    // ... Set up before login.

    // Login. Exception will occur if failed.
    con.login("username", "password");

    // Communicates with the target.
}
// Closed automatically after exiting a block.

Methods

`setTimeout(msec)`	Sets a timeout in millisec.
`setPrompt(prompt)`	Sets a prompt to wait for.
`getFingerprint()`	Returns the computed digest of the remote system’s hostkey in SHA1.
`getUserAuthList()`	Returns the list supported authentication methods.
`sendKeepAlive()`	Sends a keepalive message if needed.
`open(f)`	Opens a SSH session.
`close()`	Closes a SSH session.
`login(user, pass)`	Logins with a specified username and a password
`logout()`	Logouts from the target host.

`println(...a)`	Sends a message to the target host with a newline.
`waitfor(pattern)`	Waits for a text matched by the specified pattern.

Some Examples

Normal Use

Here is an example about normal use of SSH.

using net.Ssh;

var [, user, pass] = $$;

var ssh = new Net.Ssh("127.0.0.1");
# ssh.setTimeout(100); # for connection timeout.
ssh.open { &(con)
    System.println("Fingerprint: ", con.getFingerprint());

    con.setTimeout(10000);  # for user auth timeout.
    con.login(user, pass);
    System.println("UserAuthList: ", con.getUserAuthList());

    con.println("ls -lha");
    var mes = con.waitfor();
    System.println(mes);

    con.logout();
};
