Ultra shortcut for ssh root@

When you have to manage lot of servers, it's boring to type ssh root@myhost for each connection. Now you can type juste "s someting" and you are connected.

You can too add bash_completion script to complet with tab the name of your servers. This will be the next tips from me ;)

ssh user@server | tee logfilename

Record output of any command using 'tee' at backend; mainly can be used to capture the output of ssh from client side while connecting to a server.

Optionally, you can create a new function to do this with a custom command. Edit $HOME/.bashrc and add:

myssh () { ssh $1 | tee sshlog ; }

Save it.

At command prompt:

myssh user@server

diff <(ssh alice cat /etc/apt/sources.list) <(ssh bob cat /etc/apt/sources.list)

Execute a sudo command remotely, without displaying the password

The ssh command alone will execute the sudo command remotely, but the password will be visible in the terminal as you type it. The two stty commands disable the terminal from echoing the password back to you, which makes the remote sudo act as it does locally.

SSH connection through host in the middle

Unreachable_host is unavailable from local network, but it's available from reachable_host's network. This command creates a connection to unreachable_host through "hidden" connection to reachable_host.

Check for login failures and summarize

This command checks for the number of times when someone has tried to login to your server and failed. If there are a lot, then that user is being targeted on your system and you might want to make sure that user either has remote logins disabled, or has a strong password, or both. If your output has an "invalid" line, it is a summary of all logins from users that don't exist on your system.
