Mosh 2

A simple but powerful alternative frontend for Mosh

Key Features

  • Simple and portable
  • Supports SSH command line arguments without any change
  • Developed for performance. Connect in as low as ~0.020s.
  • Provides session caching for instant connection

Requirements

  • Mosh
  • Not a requirement, but tested only on Ubuntu

Installation

  • Just run wget -q https://raw.githubusercontent.com/VarunAgw/Mosh-2/master/install.sh -O - | bash and then restart your shell program!

Features

Supports SSH command format

In SSH you do ec2 -v -p 2020

In Mosh you have to do: mosh ec2 --ssh="-v -p 2020"

In Mosh 2 you can just do: mosh ec2 -v -p 2020

Support SSH Multiplexing

Original Mosh client disable SSH multiplexing with no workaround to enable it. With multiplexing, you can re-use existing TCP for multiple concurrent SSH sessions rather than creating a new one each time. Result is much faster connections.

# Without SSH Multiplexing
$ time ssh ec2 ls >/dev/null

real    0m1.965s
user    0m0.016s
sys     0m0.008s

# With SSH Multiplexing
$ time ssh ec2 ls >/dev/null

real    0m0.375s
user    0m0.004s
sys     0m0.000s

To enable SSH Multiplexing, add this on in your ~/.ssh/config

Host *
        ControlPath /var/tmp/ssh-%r@%h:%p
        ControlMaster auto
        ControlPersist 5m

For more information regarding Multiplexing, see [this] (https://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing).

Session caching

It supports caching of a new SSH session. So a new cached session will always be ready for you to access anytime. It can reduce session connection time to ~0.020s

To use this feature, just replace mosh with mosh-cache in your commands.

Provide shortcode for --predict=experimental

In Mosh you have to do: mosh ec2 --predict=experimental

In Mosh 2 you can just do: mosh ec2 -pe
