Open ports for ftp, ssh and webserver
I'm looking for the code to open my ports from my ftp, ssh and webserver to the internet.
I've tried several things but none of those worked.
I'm running my ftp, ssh and webserver on a virtual machine on my laptop.
I think the ports are 21 (ftp), 23 (ssh) and 80 (web server)
Can someone help me?
