Well, right-clicking has been blocked on this level. What can I do !?

Note: I will save the passwords in a file called natasX where X is the level number and will start every level by defining a URL variable.

Oh wait, I was using curl to begin with another easy level.

URL=http://natas1.natas.labs.overthewire.org

curl --user natas1:$(cat natas1) $URL

Once again, the password is easily found in the HTML. Easy peasy.

More curling (and a little bit of linux magic to get the password -> I store the password in a file called natas1 and cat it to the curl command)

curl --user natas1:$(cat natas1) $URL | 
grep "natas2" | sed 's/.*is //' | sed 's/ -*.//' > natas2
