Why does "Shields Up" show Port 443 open?
Why does "Shields Up" show Port 443 open?
Hi!
I recently had "Shields Up!" test the security of my PC and it revealed that port 443 was open and another port whose number I can't quite remember was closed instead of being in stealth mode. Could anyone please tell me how to fix this problem so my PC were totally invisible from out there?
Thanks for any comments!

typing netstat -lp should display any ports that are open (listening) and what program is using the port
443 is usually used by SSL (encrypted web pages) ... if you are running a web server, 443 will probably be open
if you have a router or cable/dsl modem with a built in firewall, it could be the router or modem that is responding to the port (or pings), not Puppy ... in that case, you would have to configure the router or modem to close the port
it is not absolutely necessary to have all incoming ports stealthed
the Morizot firewall in the start menu (Setup, Wizards) should stop all incoming traffic by default

I don't run a web server but I do have a cable modem. I installed Morizot and then did the security test with the above mentioned results which I was not really satisfied with so I installed Linux Firewall but still had that port open (and the other one 'closed'). If you say that it doesn't pose a threat then I'll stop worrying about it and just leave it as it is now. However, I do quite a bit of shopping on the net so I really don't want to expose any of my confidential data.
By the way, my PC didn't respond to pings.
Could you tell me where can I start if I want to configure my modem? Please note that I'm a newbie (but you probably know that anyway)
Thanks!

if your port 113 is visible, it might be your modem that is responding ... the only way i can close it on my router is to forward the port
there's some information at http://www.portforward.com/ on ports and specific hardware
your machine might work better if it responds to pings and ports like 113 (it's the way the internet is supposed to work) ... your computer uses these things to interface efficiently with other machines
you don't really need to be totally "stealthed" ... if my machine is stealthed, i seem to get less traffic trying to worm into the dcom system (which Linux does not have anyway ... i always disable Window's dcom using the tool on grc.com) ... worms are sorta like Night of the Living Dead

Well, I'll have to dig into this issue a bit deeper I think because I'm getting confused... I've heard that if a computer doesn't answer ping that's a positive thing, so says grc.com, it also states that it is quite dangerous to leave port 443 open. If it's not crucial that my computer is entirely stealthed in order to not jeopardize my personal data (i.e credit card number, passwords etc.) then I'm not gonna mess with it. But port 113 was either stealthed or closed. I'm gonna familiarize myself with the role of ports so i'll have a better understanding of the way they work and I hopefully won't have to ask dumb questions...
Thanks for your help!!

Good luck! I was amazed at how little information I could find about what ports are and how they work, considering how fundamental the concept of ports is to TCP/IP implementation.Anonymous wrote:...I'm gonna familiarize myself with the role of ports so i'll have a better understanding of the way they work and I hopefully won't have to ask dumb questions...
