ssh-graveyard

ssh-graveyard is a small Bash utility that reads your SSH config, lists concrete Host entries, and checks which targets still respond to ping.

Demo

ssh_graveyard_video.mp4

It prints a table with:

• HOST: the SSH alias from your config
• HOSTNAME: the resolved hostname from ssh -G
• VIA: whether the host is reached directly, through ProxyJump, or through ProxyCommand
• STATUS: whether the host appears alive or unreachable

Requirements

• Bash
• OpenSSH (ssh)
• awk
• ping
• An SSH config file, defaulting to ~/.ssh/config

Install

Install ssh-graveyard into ~/.local/bin:

mkdir -p ~/.local/bin && curl -fsSL https://raw.githubusercontent.com/aj-arts/ssh-graveyard/main/graveyard.sh -o ~/.local/bin/ssh-graveyard && chmod +x ~/.local/bin/ssh-graveyard

If ~/.local/bin is not already on your PATH, add this to ~/.zshrc or ~/.bashrc:

export PATH="$HOME/.local/bin:$PATH"

Then reload your shell:

source ~/.zshrc

Usage

Run it from any terminal:

ssh-graveyard

Or point it at a different SSH config:

SSH_CONFIG=/path/to/config ssh-graveyard

Notes

• Wildcard and negated host entries are skipped.
• Host details are resolved with ssh -G, so values inherited from other SSH config sections are taken into account.
• Reachability is based on ICMP ping, which may report unreachable for hosts that block ping even if SSH still works.
