Most people think controlling SSH access is just about creating users.

It’s not. By default, every user on your system can try to log in via SSH, which includes service accounts, app users, and anything else running on your server.

That’s a bigger risk than it should be.

🔐 SSH tip of the day:

Allow only specific users or groups. Block everything else.

AllowUsers ravi deploy
# or
AllowGroups sshusers

Quick Linux tip 🐧

Want to quickly create a backup of a file before editing it?

$ cp nginx.conf nginx.conf.bak

Or with a timestamp so you always know when the backup was made:

$ cp nginx.conf nginx.conf.$(date +%F)
# nginx.conf.2026-04-15

A small habit that has saved me from disasters more times than I can count 😅

Most sysadmins set up SSH and forget about it, but bots are hammering port 22 every single minute - hundreds of attempts per hour, fully automated, from dozens of IPs.

Here's how to make them stop:

🔐 SSH tip of the day:

Install fail2ban and add this to /etc/fail2ban/jail.local:

[sshd]
enabled = true
port = 2222
maxretry = 3
bantime = 3600
findtime = 300

Want the full setup with rate limiting, IP whitelisting, incremental bans, and how all four layers work together?

Chapter 18 of our #SSH course covers it end-to-end.

echo "Backing up server $1"
rsync -av /data root@server$1:/backup

@hrprtsingh9 100% valid point.
460 members means 460 people who raised their hand and said yes to TecMint Pro.

Converting them is the next battle.
