nohostname

i wonder who is behind this massive hack, is it a positive or even worst group?

i wouldn't want to be in the private pictures leaked once the world knows you are responsable for torture and murder of potential innocent people, very nasty karma

iptables can be scary (for beginners), ufw makes it easy but is still better to know how to handle routes with iptables imho

i have to look into sshuttle, i heard it's good

well the article is actually about a couple of commands but to explain them in details you need some more text. once you got to know how it works you can improve further and use other software like you do

sure it works, if you are happy with default configurations. the article gives informations on how things works and how to improve security

thanks for suggesting autossh ;)
