SSH & Remote Administration
Stop SSH from hanging indefinitely when your remote connection drops
🧩 The Challenge
You’ve been there, staring at a frozen terminal because your laptop went to sleep or the hotel Wi-Fi decided to take a permanent vacation. Watching the cursor blink while you try to force quit your local session is pure agony.
đź’ˇ The Fix
Tweak your SSH config to send keepalive packets at regular intervals. It forces the connection to die cleanly so your local shell doesn’t hang forever.
echo "ServerAliveInterval 60" >> ~/.ssh/config
echo "ServerAliveCountMax 3" >> ~/.ssh/config⚙️ Why It Works
By sending a null packet every minute, the client realizes the pipe is broken and drops the connection rather than waiting for a TCP timeout that might never trigger. The count max defines how many failures to ignore before giving up.
🚀 Pro-Tip: Add these to your global /etc/ssh/ssh_config if you want the sanity for every user on the box.
