What is ClusterSSH?
ClusterSSH is an open-source terminal emulator and cluster admin tool designed for simultaneous administration of multiple Linux servers. It allows sysadmins and DevOps engineers to execute commands on multiple remote hosts at the same time through a single terminal window.
Some key features of ClusterSSH include:
- Ability to open connections to multiple servers with a single click
- Organize servers into logical groups for easier management
- Broadcast commands to all connected servers or select groups
- Color-coded output makes it easy to identify which server output belongs to
- Supports passwordless SSH with public key authentication
- Unicode support for managing servers in different languages
- Sessions can be load-balanced across multiple terminal windows
- Comprehensive ACL system for access control
- Works over SSH so no agents or custom software needed on managed nodes
ClusterSSH speeds up administering common tasks like executing ad-hoc commands, copying files, managing configurations etc. Its unique grid-like interactive terminal access across multiple servers can boost productivity for sysadmins, SREs, DevOps practitioners when managing a server fleet or cluster.
