Daily Notes: Mosh Setup

I couldn’t stand the lagging on SSH anymore. In order to have a better connection with the VPS, I decided to use Mosh.

Official Site: https://mosh.org/

Installation

• Install mosh locally/client side: you can download the package for your OS on the website or you can use package control whichever suits you better.

• Server side, I’m on Ubuntu 18.04 LTS for my VPS so here’s what I did:

  $ sudo apt-get install mosh
  # install it first
    
  # or if your Ubuntu doesn't come with updated apt:
  # $ sudo apt-get install python-software-properties
  # $ sudo add-apt-repository ppa:keithw/mosh
  # $ sudo apt-get update
  # $ sudo apt-get install mosh
    
  # firewall config, support for mosh:
  $ sudo ufw allow 60000:61000/udp
    
  # then you can check your firewall status:
  $ sudo ufw status

Now you can connect to VPS, still on SSH, but the command becomes: mosh user@server_ip_address instead of ssh ...

Troubles?

I ran into a problem after mosh command:

The locale requested by LC_CTYPE=UTF-8 isn't available here.
Running `locale-gen UTF-8' may be necessary.

If you have the same issue, here’s an easy fix:

# run this code on both your client/local and server:
$ export LC_ALL="en_US.UTF-8"

I tried $ export LC_ALL="en_CA.UTF-8" and for some reason it doesn’t work… Why does it have to be US??
