SSH and the shell: go forth securely

presented by der.hans

SSH is the go to tool for sysadmins and developers for interactive connections to remote machines. It creates secure, encrypted connections between computers, even across hostile networks. Unless you accept keys without verification (DON'T DO THAT!!!).

SSH can also create tunnels for encapsulating other connections, including other protocols and data. Sysadmins can bridge protocols across ne...

Keepassing your credentials synced and under control

Do you use the same few passwords over and over? Is there a piece of paper with hard-to-remember ones somewhere? How about a file that lives on five different devices and is never up-to-date?

Even the most secure passwords can be broken with a $5 wrench. Long forgotten websites are frequently compromised. Files can be stored in The Cloud, but is that really where such sensitive data should b...
