High level Kotlin SSH API for easy and fast operations on remote servers. This is a Kotlin port of the Scala JASSH library.

The API is JSCH based.

It requires a local user named "test" with password "testing", remember that you can remove the password, if your public key has been added in authorized_keys file of the test user.

#!/bin/sh
exec java -jar kossh.jar "$0" "$@"
!#
kossh.impl.SSH.once("localhost", "test", "testing") { 
  print(execute("""echo "Hello World from $(hostname)" """))
}

#!/bin/sh
exec java -jar kossh.jar "$0" "$@"
!#
kossh.impl.SSH.shell("localhost", "test", "testtest") {
  println("initial directory is $pwd")
  cd("/tmp")
  println("now it is $pwd")
}

This functions much the same as a regular SSH connection, but many of the unix like commands are not supported and the terminal behaves differently

import kossh.impl.*

val settings = SSHOptions(host = host, username=user, password = pass, prompt = prompt, timeout = timeout)
val session = SSH(settings)

val shell = session.newPowerShell()

println(shell.ls())
println(shell.pwd())

To turn on/off ssh root direct access or sftp ssh subsystem.

    Subsystem       sftp    ...     (add or remove comment)
    PermitRootLogin yes or no       (of course take care of security constraints)
