Port 443?

[D. D. Brierton]

Can anyone tell me what listens on port 443? I've just noticed the
following in my /etc/sysconfig/iptables:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

and I can't for the life of me remember putting it there. I'm fairly
safe as I'm behind a NAT router and the only ports forwarded are TCP
6881-6889 for BitTorrent. However, I'm just puzzled as to where the
above rule came from. It is possible that I added it myself when I was
trying to do some simple networking with a Mac and subsequently forgot
about it, or its possible that the configure scripts for VMware or Zope
added it. I'm just curious really.

TIA, Darren

D'Oh! Of course it is. I knew that, I just didn't now that I knew it.
Thanks for pointing out the obvious. That rule is indeed meant to be
there -- I enabled HTTP(S) in system-config-securitylevel.

Thanks again.

Best, D

could be
-------
# lsof -Pi :443
COMMAND  PID   USER   FD   TYPE DEVICE SIZE NODE NAME
httpd   5543   root    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5546 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5547 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5548 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5549 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5550 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5551 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5552 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
httpd   5553 apache    4u  IPv6  54890       TCP *:443 (LISTEN)
-------

but must not be
-------
# lsof -Pi :443
COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME
sshd    5682 root    3u  IPv6  57361       TCP *:443 (LISTEN)
