I have installed webserver (apache) but I can't seem to make netcat connect to it.
$ curl localhost:80 | head

I've also tried the same experiment with nginx before. With the same results.
I'm on debian and there's no firewall active, what am I doing wrong?

The problem was that the netcat that was installed was netcat-traditional which does not support IPV6 and for some reason both apache2 and nginx were listening only on the IPV6 loopback.
The solution was to install and use netcat from openbsd and netcat could connect with either
nc ::1 80
ornc localhost 80
.
