Mosh

Mosh is similar to SSH, remote terminal application but it allows roaming, and supports intermittent connectivity. Its usage is similar to SSH. It has to be installed both on the server and client.

On RedHat/CentOS remote server:

sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

sudo yum install mosh

sudo firewall-cmd --zone=public --permanent --add-port=60000-61000/udp

sudo firewall-cmd --reload

Azure:

On local Mac:

brew install mosh
