ssh2.cr
This library provides binding for libssh2 library.
Status
Alpha
Requirements
- Crystal language version 0.17 and higher.
- libssh2 version 1.5.0 or higher
You can use homebrew
to install the latest libssh2:
$ brew install libssh2
Goal
The goal is to utilize libssh2 API by providing services like ability to run shell commands via ssh as well as scp and sftp services.
Usage
An example of running a shell command via SSH on the remote server:
require "./src/ssh2"
SSH2::Session.open("my_server") do |session|
session.login("username", "password")
session.open_session do |channel|
channel.command("uptime")
IO.copy(channel, STDOUT)
end
end
An example of running shell:
require "./src/ssh2"
SSH2::Session.open("localhost", 2222) do |session|
session.login_with_pubkey("root", "./spec/keys/id_rsa")
session.open_session do |ch|
ch.request_pty("vt100")
ch.shell
session.blocking = false
buf_space = uninitialized UInt8[1024]
buf = buf_space.to_slice
loop do
io = IO.select([STDIN, ch.socket]).first
if io == STDIN
command = gets
if command
ch.write(command.to_slice)
end
elsif io == ch.socket
len = ch.read(buf).to_i32
print String.new buf[0, len]
break if ch.eof?
end
end
end
end
An example of using SFTP API:
require "./src/ssh2"
SSH2::Session.open("localhost", 2222) do |session|
session.login_with_pubkey("root", "./spec/keys/id_rsa")
session.sftp_session do |sftp|
sftp.open_dir(".").ll do |fn|
puts fn
end
file = sftp.open(".bashrc")
puts file.gets_to_end
end
end
Testing
In order to run test suite you need to pull and run the following docker container:
$ docker pull tutum/ubuntu:trusty
$ docker run -d -p 2222:22 -e AUTHORIZED_KEYS="`cat ./spec/keys/id_rsa.pub`" tutum/ubuntu:trusty
