Net::SSH::Gateway¶ ↑

• github.com/net-ssh/net-ssh-gateway

DESCRIPTION:¶ ↑

Net::SSH::Gateway is a library for programmatically tunnelling connections to servers via a single “gateway” host. It is useful for establishing Net::SSH connections to servers behind firewalls, but can also be used to forward ports and establish connections of other types, like HTTP, to servers with restricted access.

FEATURES:¶ ↑

• Easily manage forwarded ports

• Establish Net::SSH connections through firewalls

SYNOPSIS:¶ ↑

In a nutshell:

require 'net/ssh/gateway'

gateway = Net::SSH::Gateway.new('host', 'user')

gateway.ssh("host.private", "user") do |ssh|
  puts ssh.exec!("hostname")
end

gateway.open("host.private", 80) do |port|
  Net::HTTP.get_print("127.0.0.1", "/path", port)
end

gateway.shutdown!

# As of 1.1.0, you can also specify the wait time for the
# gateway thread with the :loop_wait option.
gateway = Net::SSH::Gateway.new('host', 'user', :loop_wait => 0.001)

See Net::SSH::Gateway for more documentation.
