Is there a way to ping an IP address range in a LAN? [ip address range] [correct ports]

Q: Just added a Vonage modem to the network, but I must know the IP, so I can FWD the appropriate ports.

If you have nmap it will do that as well.

I can't believe it took this long for someone to suggest nmap… its great


Re:I'd start by finding filmaker.com and seeing where it lives. Have you ever used HijackThis from http://mjc1.com/mirror/hjt/ ? I'd start with that and see if you can find what malware you are carrying around with you. :) I think this is really a topic for the virus forums…

I guess they think you have a Trojan, I'm not familiar with the name. However, unless you're running something specific that uses port 5000, I'd suggest that doesn't really belong there. :)

I really don't understand how to get rid of it, could you please explain?


Re:I clicked on the link for you, did you get it? ;)

Perhaps a URL would have made this post more useful…

What, too lazy to google? ;)

IP Tools is a great app for IP scans and other tools to play around with.

Cruise to <a href="http://www.foundstone.com">www.foundstone.com</A> (http://www.foundstone.com">www.foundstone.com</A>) and pick up their free IP scanner.

I used the program here and when I ran it I got this as the result. (http://pics.bbzzdd.com/users/guy/123.JPG)What does the cicled part mean? Do I have a trojan?


Re:The program you will want to use is Angry IP Scanner (http://www.angryziber.com/ipscan/). It's free, small, and works great – use it all the time at work.

Re:You could write a script to do it. pick your language, something along the lines of this. (don't use this as code, it is just basic syntax example…)

for (n = 1; n <= 255, n++) {
$output = ping 192.168.1.n;
print $output;
}


Re:There's a bunch of freeware programs that will ping a range of IPs and report back the ones that are alive. Search download.com for Angry, I use it all the time.

Re:Nah there's nothing that shows that unfortunately. I have/had an old D-Link.

Re:Holy crap! Doing that just changed my public ip address…which never happened before in the last 3 years. Interesting. The Vonage box acts as a NAT so I just replaced the ol' D-Link with it. Maybe that has something to do with it. This thing has some of the most barebones features I've seen….

Re:In your router setup menu it should have an option to see all attached computers.
