Resources

Mosh is a SSH client server that is aware of connectivity problems of the original SSH implementation. Mosh can migrate physical connections and IP addresses while staying connected. Mosh depends on SSH.

Emerge

Install net-misc/mosh :

root #emerge --ask net-misc/mosh

Configuration

Mosh requires UTF-8 locales to be set in order to run. To check, run:

user $locale -a

In case it does not return the UTF-8 locale see UTF-8#Setting up UTF-8 with Gentoo Linux.

Firewall

Each mosh client requires a free and accessible UDP port between 60000 and 61000 on the server to function.

With Ufw, allow these ports with:

root #ufw allow 60000:61000/udp

Usage

Connecting

Once the remote host has SSH running, mosh installed, and the UFT8 locale set connection is possible:

user $mosh user@remote-host.com
