assh

Overview

A transparent wrapper that adds support for regex, aliases, gateways, dynamic hostnames, graphviz, json output, yaml configuration, and more to SSH.

lib-ssh wraps assh as a ProxyCommand; it means that it works seamlessly with:

• ssh
• scp
• rsync
• git
• Desktop applications depending on lib-ssh or ssh (i.e., Tower, Atom.io, SSH Tunnel Manager)

For specific examples, see 3rd Party Integration

Features

Configuration features

• regex support
• aliases gate -> gate.domain.tld
• gateways -> transparent ssh connection chaining
• includes: split configuration in multiple files, note that OpenSSH as of v7.3 has native support for this
• local command execution: finally the reverse of RemoteCommand
• templates: equivalent to host but you can't connect directly to a template, perfect for inheritance
• inheritance: make hosts inherits from host hosts or templates
• variable expansion: resolve variables from the environment
• smart proxycommand: RAW tcp connection when possible with netcat and socat as default fallbacks
• rate limit: configure a per-host or global rate-limiting
• JSON output
• Graphviz: graphviz reprensentation of the hosts

Using Gateway from command line

assh can use the ProxyCommand with netcat feature of OpenSSH transparently and without the pain of using extended configuration.

Connect to hosta using hostb as a gateway.

$ ssh hosta/hostb/hostc
user@hosta $

Equivalent to ssh -o ProxyCommand="ssh -o ProxyCommand='ssh hostc nc %h %p' hostb nc %h %p" hosta

Using Gateways from configuration file

You can define an equivalent of the "ProxyCommand with netcat" feature of OpenSSH, with a simpler syntax, more advanced workflows, and a unique fallback feature.

Let's consider the following assh.yml file

hosts:
  hosta:
    Hostname: 1.2.3.4

  hostb:
    Hostname: 5.6.7.8
    Gateways: hosta

  hostc:
    Hostname: 9.10.11.12
    Gateways: hostb

  hostd:
    Hostname: 13.14.15.16
    GatewayConnectTimeout: 2
    Gateways:
    - direct
    - hosta

• ssh hosta -> ssh 1.2.3.4
• ssh hostb -> ssh -o ProxyCommand="ssh hostb nc %h %p" hosta
• ssh hostc -> ssh -o ProxyCommand="ssh -o ProxyCommand='ssh hostc nc %h %p' hostb nc %h %p" hosta
• ssh hostd ->
  • assh will try to ssh 13.14.15.16
  • then, fallback on ssh -o ProxyCommand="ssh hostd nc %h %p" hosta
  • this method allows you to have the best performances when it is possible, but ensure your commands will work if you are outside of your company for instance

Under the hood features

• Automatically regenerates ~/.ssh/config file when needed
• Inspect parent process to determine log level (if you use ssh -vv, assh will automatically run in debug mode)
• Automatically creates ControlPath directories so you can use slashes in your ControlPath option, can be enabled with the ControlMasterMkdir: true configuration in host or globally.

Hooks

Events

BeforeConnect

BeforeConnect is called just before assh tries to connect to the remote SSH port.

Note: BeforeConnect will be called for each SSH connection; if you use multiple gateways, it will be called for each gateways until one succeed to connect.

---

Example of Golang template variables:

// Host: http://godoc.org/moul.io/assh/pkg/config/#Host
{{.Host.Name}}                                  //  localhost
{{.Host.HostName}}                              //  127.0.0.1
{{.Host.Port}}                                  //  22
{{.Host.User}}                                  //  moul
{{.Host.Prototype}}                             //  moul@127.0.0.1:22
{{.Host}}                                       //  {"HostName":"localhost","Port":22","User":"moul","ControlPersist":"yes",...}
{{printf "%s:%s" .Host.HostName .Host.Port}}    //  localhost:22

OnConnect

OnConnect is called as soon as assh is connected to the remote SSH port.

Note: OnConnect is not aware of the authentication process and will always be raised.

---

Example of Golang template variables:

// Host: http://godoc.org/moul.io/assh/pkg/config/#Host
{{.Host.Name}}                                  //  localhost
{{.Host.HostName}}                              //  127.0.0.1
{{.Host.Port}}                                  //  22
{{.Host.User}}                                  //  moul
{{.Host.Prototype}}                             //  moul@127.0.0.1:22
{{.Host}}                                       //  {"HostName":"localhost","Port":22","User":"moul","ControlPersist":"yes",...}
{{printf "%s:%s" .Host.HostName .Host.Port}}    //  localhost:22

// Stats: http://godoc.org/moul.io/assh/pkg/commands/#ConnectionStats

OnConnectError

OnConnectError is called when assh fails to open a new TCP connection.

---

Example of Golang template variables:

// Host: http://godoc.org/moul.io/assh/pkg/config/#Host
{{.Host.Name}}                                  //  localhost
{{.Host.HostName}}                              //  127.0.0.1
{{.Host.Port}}                                  //  22
{{.Host.User}}                                  //  moul
{{.Host.Prototype}}                             //  moul@127.0.0.1:22
{{.Host}}                                       //  {"HostName":"localhost","Port":22","User":"moul","ControlPersist":"yes",...}
{{printf "%s:%s" .Host.HostName .Host.Port}}    //  localhost:22

// Error
{{.Error}}                                      //  dial tcp: lookup localhost: no such host

OnDisconnect

OnDisconnect is called as the assh socket is closed.

warning: if you don't see a notification when closing an SSH connection, then you probably have ControlMaster configured; OnDisconnect is not linked to the ssh program but to its socket which may stay alive even after exiting the ssh program.

BeforeConfigWrite

BeforeConfigWrite is called just before assh rewrite the ~/.ssh/config file.

Example of Golang template variables:

{{.SSHConfigPath}}                               // ~/.ssh/config

Hooks drivers

Exec driver

Exec driver uses Golang's template system to execute a shell command

Usage: exec <binary> [args...]

defaults:
  Hooks:
    OnConnect: exec echo '{{.Host}}' | jq .
# executes: `echo '{"HostName":"localhost","Port":"22","User":"moul","ControlPersist":"yes",...}' | jq .
# which results in printing a pretty JSON of the host
# {
#   "HostName": "localhost",
#   "Port": "22",
#   "User": "moul",
#   "ControlPersist": "yes",
#   ...
# }

defaults:
  Hooks:
    OnConnect: exec echo 'New SSH connection to {{.Host.Prototype}}.' | mail -s "SSH connection journal" m+assh@42.am
# send an email with the connection prototype

defaults:
  Hooks:
    BeforeConfigWrite: exec cp {{.SSHConfigPath}} {{.SSHConfigPath}}.backup
# make a copy of ~/.ssh/config before being rewritten

defaults:
  Hooks:
    AfterConfigWrite: 'exec echo "# date: `date`" >> {{.SSHConfigPath}}'
# Append a comment with the compilation date to the generated ~/.ssh/config file

defaults:
  Hooks:
  AfterConfigWrite: 'exec cat /path/to/my/provider/generated/.ssh/config >> {{.SSHConfigPath}}'
# Append another .ssh/config file to the generated .ssh/config file

---

The exec commands are blocking, a new driver for background tasks is planned. For now, you can run a job in background like this:

defaults:
  Hooks:
    OnConnect:
    - exec sleep 60 &
# execute the `sleep 60` command in background (non-blocking)
# if you quit your ssh connection, the process will continue in background.

Write driver

Write driver uses Golang's template system to write out data to stdout

Usage: write <line:string...>

defaults:
  Hooks:
    OnConnect:
    - write New SSH connection to {{.Host.Prototype}}.
# writes: "New SSH connection to moul@127.0.0.1:22." on the terminal on connection

defaults:
  Hooks:
    OnDisconnect:
    - "write SSH connection to {{.Host.Name}} closed, {{ .Stats.WrittenBytes }} bytes written in {{ .Stats.ConnectionDuration }} ({{ .Stats.AverageSpeed }})"
# writes: SSH connection to localhost closed, 40 bytes written.

Notify driver

Notify driver uses Golang's template system to open Desktop notifications.

• Mac OS X: Built-in support
• Linux: Depends on gnotifier
• Windows: Not supported
• BSD: Not supported

Usage: notify <line:string...>

defaults:
  Hooks:
    OnConnect: notify New SSH connection to {{.Host.Prototype}}.

defaults:
  Hooks:
    OnDisconnect:
    - "notify SSH connection to {{.Host.Name}} closed, {{ .Stats.WrittenBytes }} bytes written in {{ .Stats.ConnectionDuration }} ({{ .Stats.AverageSpeed }})"

Configuration

assh now manages the ~/.ssh/config file, take care to keep a backup your ~/.ssh/config file.

~/.ssh/assh.yml is a YAML file containing:

• a hosts dictionary containing multiple HOST definitions
• a defaults section containing global flags
• and an includes section containing path to other configuration files

hosts:

  homer:
    # ssh homer ->  ssh 1.2.3.4 -p 2222 -u robert
    Hostname: 1.2.3.4
    User: robert
    Port: 2222

To improve experience when using advanced pattern matching, add the following at the end of your .bashrc / .zshrc / config.fish:

alias ssh="assh wrapper ssh --"

This step is not mandatory but highly recommended.

---

Note: ssh does not understand advanced patterns; To bypass this limitation, assh maintains a list of known hosts and regenerate the ~/.ssh/config with all those expanded known hosts.

Without the wrapper, the ~/.ssh/config risks to be outdated when connecting to a new host for the first time and you will need to launch the command again.

With the wrapper, ssh will always be called with an updated ~/.ssh/config file.

Getting started

1. Backup your old ~/.ssh/config: cp ~/.ssh/config ~/.ssh/config.backup
2. Create a new ~/.ssh/assh.yml file
3. Run assh config build > ~/.ssh/config to validate the syntax of your ~/.ssh/assh.yml file and automatically build your ~/.ssh/config file
4. You are ready!

Webapp

assh contains an experimental web application hosted on heroku: https://assh.herokuapp.com/

---

Convert an assh.yml file to ssh_config format:

$ http --form POST https://assh-dev.herokuapp.com/assh-to-ssh assh_config=@~/.ssh/assh.d/test.yml | jq -r .ssh_config
# This file was automatically generated by assh v2.8.0
# on 2018-07-03 21:06:56 +0000 UTC, based on ~/.ssh/assh.yml

Docker

Experimental: assh may run in Docker, however you will have limitations:

• The assh containers does not have any binaries except assh, you can't use ProxyCommand, ResolveCommand...
• Docker may run on another host, ssh localhost will ssh to Docker host

docker run -it --rm -v ~/.ssh:/.ssh moul/assh --help

assh in Docker is slower and has more limitations, but it may be useful for testing or if you plan to use a Docker host as a remote Gateway

Alternative version

• v1 (2009-2015) - The original implementation. It worked quite well, but was a lot slower, less portable, harder to install for the user and harder to work on to develop new features and fix bugs

Troubleshooting

I can't use gateways

assh uses the built-in netcat mode of OpenSSH (shipped with OpenSSH 5.4) by default. If your ssh client doesn't support this feature, you can configure a custom ProxyCommand configuration, i.e.,

hosts:
  myserver:
    host: 1.2.3.4
    gateways: mygateway
    # configure a custom proxycommand
    proxycommand: /bin/nc %h %p

  mygateway:
    host: 5.6.7.8

---

You can configure this rule globally:

defaults:
  proxycommand: nc %h %p

---

Also, be sure to have netcat installed on your system, or use an alternative proxy binary, i.e., socat.

How to Configure resolver to parse /etc/hosts and/or handle mDNS requests

assh resolves hostnames using the system built-in resolver, depending on the OS, you can enable new features and/or change modules order.

• Linux - nsswitch documentation
• Linux - mDNS support (nss-mdns)
• Mac OS X - /etc/resolv.conf documentation

unix_listener: "/Users/.../.ssh/cm/..." too long for Unix domain socket

Starting with OpenSSH v6.7 the socket name can be shortened by configuring %C for the name expansion.

defaults:
  ControlPath: ~/tmp/.ssh/cm/%C.sock

%C is a unique identifier based on a hash of the tuple of (local host, remote user, hostname, port).

How to disable the automatic configuration rewrite

Each time you call ssh, assh will check if the generated ~/.ssh/config file is outdated.

By default, it will transparently regenerate the configuration file if needed.

You can disable this behavior by generating the configuration file like this:

assh config build --no-automatic-rewrite

3rd Party Integration

Ansible

In your ansible.cfg under ssh_connection, make sure you have the following, changing the path to your assh:

[ssh_connection]
ansible_ssh_executable = '/usr/local/bin/assh wrapper ssh'
