I tested something and I got really weird results:

- I went to grc.com to see if any ports are open my machine. MDK firewall (shorewall) is disabled!!!) >>> test PASSED = FULL stealth
cool, no firewall and alredy full stealth...

- I enabled MDK fiewall, I rebooted, went to grc.com. big surprise:
test FAILED!!! some open ports!!!


can someone explain to me please

Rebooting was pointless, and probably caused the problem. You aren't running Windows.

Turning on a firewall does not open ports. Rebooting can start services, which means open ports. Perhaps during your original uptime you turned off a service, then when you rebooted the service was restarted.

You don't say WHAT ports were opened, you merely say the test FAILED. For GRC, non stealth means FAIL. You don't need open ports to fail. Are you *sure* there were open ports?

Remember that 'stealth' is a marketing scam, so 'failing' GRC is meaningless. All that matters are open ports.

* first about rebooting...
if i turn off/on firewall, or just open the firewall config page in drakxtools, connection will drop. thats a bug! thats why i said i rebooted.
(btw i know this is NO windoze)


* second, about services...
i always keep an eye on services, no useless service running on my machine.
no service that could cause an open port!

* third, about grc... i just had the test again:
only 135/139/445 (and a few more ports) are detected as stealth...
the rest is closed

conclusion, it might have been an open port somewhere when i first tested OR there is a bug!

If your connection drops you should be able to restart it by going to the Connection Wizard in Drake. It's under network connections or whatever they call it.

I'm confused by your conclusion, but ok. Supposing you had open ports can't explain the results of the first test, since you passed the first test. > 0 ports closed = fail. > 0 ports open = fail. all ports stealth = pass. Maybe I am misunderstanding you. Passing the first test w/out a firewall means you weren't running any services. Unless there was a bug on GRC's end, but that's unlikely. If you said you had open ports *and* there was a bug, well, that would make sense.

Anyway, sounds like you're secure now.

as i (tried to) explain, after enabling firewall, there were open ports when checking firewall online. it might be a bug (from my sytem or website?). it hasnt happen again after recompilig kernel...
