port scanning probs
port scanning probs
Hi, I can't go into anyone's computer because I can never connect to an open port. When I ping the computer it gives me replies, but it never finds open ports. I am behind a router, that might be the problem. If this doesn't work, is there any way I can mess with someone's comp (not to do any harm) just by knowing their IP. Tell me if I'm not allowed to say this kind of stuff in this forum.
What exactly ports you are scanning for (21, 25, 23, 80, 110....)?When I ping the computer it gives me replies, but it never finds open ports. I am behind a router, that might be the problem
Try to scan any web server for port #80 (e.g. www.yahoo.com). If you receive answer, it means your system and IP-Tools works fine.
Then 2 versions
1) May be systems that you are scanning do not use ports that you want to find.
2) Probably some ports blocked by your firewall. Check router configuration or ask your network administrator.
I am so tired of this sort of questionis there any way I can mess with someone's comp
No answer

Sorry for the last question, it was a joke (not really funny). I am scanning for another computer on all possible ports. I turn my software firewall off (zonealarm) and still no replies. I do port scan websites and it finds the open port 80, so the program works excellently. As for the router, I made my computer on a DMZ, so it would have all access to the internet, but it still didn't work.
I thought about that and I figured all the new service packs took care of all the security, but I made it so the computer I am trying to contact is not behind a router and directly connected to the internet, no firewalls no nothing. (as unafe as possible). There should be open ports. But I do get an open port when I do a UDP scan! #53, but it says that is a DNS, and I don't think that will serve me any good.
Why there should be open ports?There should be open ports.
Port is open for listening when some sort of server (www server, ftp server, mail server, etc) is running on the system.
No special services started - no opened ports.
For example scan fast.tomato.it
You should see several open ports
Port 22 (ssh)
Port 25 (smtp)
Port 53 (domain)
Port 80 (http-www)
