Mosh is a replacement for SSH is resilient to intermittent network connections, and supports roaming (changing) network connections. Mosh can maintain a remote connection while network connections intermittently go up and down, and routes to the Internet change. Mosh depends upon Package:OpenSSH. Mosh uses udp ports 60000-61000 sequentially.
# emerge net-misc/mosh
Mosh requires UTF-8 locales set to run. This is the default for Funtoo Linux if you have not set any specific locales.
Remote host only needs running ssh, mosh package installed, and UTF-8 locale set.
