i dunno if this is a newbie question or a general question so...what does this trce route tell you? firewall? obviously the packets timed out. but why?

traceroute 210.174.0.175

Type escape sequence to abort.

ok, tracert stands for trace route. it returns every ip of every computer you connect to until you reach your destination. for example, when you connect to a site, your computer contacts your local isps server, then the main server for your area, then the main server, then it connects to a server in the area of your target, then to your targets isp, local, and finaly the actualy target.

take undergroundnews.com

Trace complete. 


thats the way it should come out, also, if possible tracert automaticaly looks up the dns' of the ips.

as for those *'s you were getting, thats because you were timing out, try to use -t 1000000000000 wink thats the timeout in miliseconds. also that -h 100 is that maximum number of hops to preform.

ah, and there was some program, i forget what it was called, that did a tracert and then a whois on each of the nodes and tried to find out the location, then it plotted all the points on a map and connected them, it was pretty coo'. i dont remember what it was called tho...

Basically it logs all hops between you and your specifide host:

Posted By: sprinter Re: tracert question - 04/09/02 02:05 AM
yeah i understand how it works i was just curious why this IP was unreachable? i havent tried changing the default time out. this is the first time i have seen an IP that would time out like this. ill try it again with the -t switch? (<--proper name here?)


ok tryed in windows shell and it says to use a -w so i di and it still times out. doesnt this have to do with the TTL? i know the TTL is time to live but i have to look up how that is determined.

so there is nothing special about the ip address i traced? or at least nothing we can get by using tracert?
Posted By: Gremelin Re: tracert question - 04/09/02 07:51 AM
perhaps it wasn't logged into the internet? either via it bein shut down or dosed heh
Posted By: SilentRage Re: tracert question - 04/09/02 02:34 PM
yep, the computer is not online, the IP is not in use. At least not at the time I checked it out.
Posted By: sprinter Re: tracert question - 04/09/02 03:37 PM
ok that makes sense but its kind of unusual. there is a pretty good chance that there is a hardware firewall there so i was just curious what i was looking at. thanks guys.
Posted By: Scallion Re: tracert question - 04/09/02 07:18 PM
You could check that ip with nslookup .(something most windows folks don't have)

For those of you who don't have nslookup, I've written a version and posted it near the bottom of www.scallion.sp00fed.net for your convinience. THis will look up the IP and tell you what it's DNS record says about it - if you get a negative result, this means that the IP has no DNS record, therefore it is unused, eliminating the need for tracert as a tool to find whether it's online or not.
Posted By: Mornse Re: tracert question - 04/09/02 10:59 PM
sprinter, you're right, it could be a firewall. Sometimes firewalls block certain requests, so either the computer doesn't exist, or you hit a firewall.
Posted By: sprinter Re: tracert question - 04/10/02 02:19 AM
SCALLION- thanks for the effort but im proficient with google and that seems to get me by on most things smile.
http://network-tools.com/

Mornse- could be a firewall i dunno. i will find out soon though smile. or at least have some more info. i would really like to know what it takes to make an addy unreachable as though its not there. a firewall? or a hardware firewall or just something like ipchains,freesco,natd or other setups like this?
