Sheilds up shows opened ports with Firestarter?
I just made my old computer into a Router/Firewall using Firestarter. I checked the firewall with the Shields Up website and it showed just a few "stealthed" ports, about 3 opened ports, and all the rest showed "closed." It said that all the ports should be "stealthed."
The opened ports really worried me. It showed OpenSSH(which I use locally), DNS(not sure if I need), and some unknown port in the 800's as opened. The only ports I have open in firestarter are port forwarded to my other pc, and that's just azureus, limewire, and a game(these were the only stealthed ports). I also set firestarter to always accept connection from my local IP. I thought firestarter is supposed to block all inbound connections unless they're specifically allowed? After this, I did set it to block all ICMP services and ran sheilds up again, and this time it showed everything as "stealthed." I don't know if this will cause any problems or not though? Is my system now firewalled or not? |
I wouldn't trust grc so much, there is lots of better scans around.
Nessus scan: http://www.it-sec.de/vulchke.htm Different pings and Dos packets. http://www.pcflank.com/scanner1s.htm Normal tcp - udp scan. http://scan.sygate.com/ Test with these if you have any open ports. |
Those all said I passed too. But...
I don't see how just filtering ICMP would close my open ports? Or were these ports really open? |
**I'm a neWb plz bear with me**
This isn't directly related to the thread and related problem but includes issues with Firestarter, open ports, security, and ultimately Azureus. I use Firestarter despite the understanding that Ubuntu (my current *nix), by default, closes all incoming ports. I have opened port 6881 for Azureus although Firestarter 'warns' it is open to anyone. At night I leave my torrents on the net to be seeded and on numerous occasions I wake up to see that various high numbered, random ports are open as an active connection ("unkown" apps/service), including various connections, as expected, on port 6881. Finally, they, according to Firestarter, stay active after Azureus is terminated. Is this a serious problem? Any ideas as to why the ports stay open? Related at all to exploits or bugs in Azureus? |

You should check your firewall configuration to see what it's set to block and allow. If SSH is really opened from the Internet, that might not be what you wanted. |
