originSH has already told you what influence this has, stil, you don't get it. OK.

I know the answer, but I certainly won't tell you.

Hi - trying to check connectivity with tracert command

(1) from here to pdir.bloomberg.net
C:\>tracert pdir.bloomberg.net

Tracing route to pdir.bloomberg.net [206.156.53.131]
over a maximum of 30 hops:

What's with the timed out?

(2) how do I check connectivity to a subnet:

<br />
208.134.161.0 [255.255.255.0]

Thanks very much!

(1) That means that tracert stopped waiting on a reponse by that node because it took too long.

(2) Use Ping. ICMP Type 3 Code 0 is for "Network unreachable". You might get that reply from a chatty (not stealthy) router which realized it has no port to send your ping request to.

However, these computers could be anywhere, they don't have to be in the same room physically, so "checking for subnet connectivity" is not something you usually do.

Sebastian

Like the other poster said, there are 3 possibilities.

1. The 11th hop is down for some reason.

2. The 11th hop takes too long to respond, where TRACERT times out and give up waiting for a response.

3. The 11th hop is configured to ignore/drop/misroute ICMP ECHO requests.

Thanks - I get timeout after hop 11th. Is it possible for me to get timeout on 11th hop, then some response say 115ms from 12th hop, then timeout again on 13th hop?

30th hop total - what does it suggest? max depends on routing protocol? 30 seems a big number...?

Oh yeah it is. This happens, usually, because of a router configuration problem, but can also be caused by a bad link between the 11th and 12th hop. The 11th hop can time out and you get a response back from the 12th hop, probably because the reply packet had another path back to your machine.

When you send a ping packet down a route, there is NOTHING that says the reply packet has to take the same route back! The replys can take take route available to get back to your machine.

By default, TraceRoute will only go the first 30 hops. There is no way for it to know how many hops are actually in the path to the destination, so in the event of a Timeout, TraceRoute just assumes that A hop failed. It has no way of knowing WHICH hop failed, or how many hops are required to reach the destination machine.

Option 3 is highly likely in the modern internet. No sense allowing attackers to know that you're there. It's amazing anything responds to 'trace route' packets nowadays.

have an application in visual c++ relating to client and server. this appliaction does many types of work like getting all user names logged on to computers,remote shutdown,remote logoff, getting the remote desktop view and many others types of functioning related to "lan monitoring" through server. but for this , client application has to be executed all the time whenever any user logon through his local account.
but the problem is that I couldn't find any way to execute the "client exe" automatically whenever any user logon through his/her local account.But I could execute the client exe automatically for the administrator by making changes in the registry but I have to execute it "for all users".

So please help me to find any way to execute the client exe for all users automatically whenever they logon through their local account.Is there any win api or by making any registry changes or any program which can call the exe automatically whenever any user login.

ps:since this is all a part of a domain so all the other users are less priviliged than admin

That really, really makes me want to delay giving my answer by another couple of hours :P

Putting anything like isn't going to make anyone rush to help you any quicker than they normally would. If your problem is time critical go pay someone to help, if you want free help be prepared to wait on other people because they have jobs and other stuff which is more important and URGENT than you.

Heres your answer anyway:

Stick a shortcut to the app in "C:\Documents and Settings\All Users\Start Menu\Programs\Startup" and whenever a user logs in it'll start up. Obviously making sure that C:\ is actually whichever drive the system is installed on.

If you're an administrator, right-click the Start button and select Open All Users. That opens the folder to the right location.

I prefer TaskManager Extension from CodeProject. It is not a commandline but a rich GUI which plugs itself into the existing TaskManager.
