I am currently learning network interfaces.
Below, using netstat, I listed interfaces with respective ports:
True or False
Please correct if wrong. If I were to translate this in my own words it would go like this:
- Anyone with
ipv4
andipv6
address can connect to my host viaSSH
- Anyone with
ipv6
address can connect to my host viahttp
through port80
- No one with
ipv4
address can connect to my host viahttp
Question
Why is smtp
bound to localhost
? My understanding was that a mail server should be accessible to the outside world so computers can communicate.
