Mosh – Mobile Shell

Mosh (mobile shell) is a remote terminal application that supports intermittent connectivity. It handles network switching and roaming better than SSH, making it ideal for mobile and unreliable connections.

Key Features

• Roaming: Survives network changes
• Instant Response: Local echo for typing
• UDP Based: More resilient than TCP
• SSH Authentication: Uses SSH for initial connection
• State Synchronization: Recovers from disconnects

Installation

Install Mosh on Ubuntu:

sudo apt update
sudo apt install mosh

Usage Examples

Using Mosh:

# Connect to remote host
mosh user@hostname

# Specify SSH port
mosh --ssh="ssh -p 2222" user@hostname

# Use specific mosh server port
mosh -p 60001 user@hostname

# Predict mode (less latency)
mosh --predict=always user@hostname

Benefits

Mosh provides reliable terminal sessions over unstable connections. Its intelligent local echo and automatic reconnection make remote work seamless.
