1.4.1 has been uploaded. The error handling isn't added yet but hopefully the one I did add will catch that error.

 

[lemonadesoda]

Nice fixes in 1.4.1

Why does a ping (e.g. to techpowerup.com) take 140ms whereas a remote port scan to the same address times out at 500ms? Maybe there is nothing that can be done... and this is a code quirk. But is there a "real" explanation for this?

I think there is a button missing: a button with just the TPU logo that JUMPS TO THIS THREAD , or at least, a help thread, once you have written one

 

[lemonadesoda]

Intranet scan needs some work/thinking about.

The output is unsorted and has lots of redundant data.

The error is there... but it still completed the run.

What are you entering to make the Remote Port Scan timeout?

500ms comes from a thread that monitors the port scans (retires them, basically). It runs every 500ms so that is the absolute minimum time it will take to finish the port scan. Ping is a better indicator of network performance.

A good idea but, I think I'll wait on that one (would need Wizzard's blessing and a permanent home).

Ugh, it strikes again. I spent like three hours trying to prevent it from listing everything and I thought I had it fixed. My only permanent solution is to only display those that have a name.

I was hoping it would catch the error but apparently it didn't. I just gone done adding a system for handling exceptions so I'll make sure it is covering the intranet code...

1.4.2 has a more robust Whois system.

1.4.2 uploaded. Description on the original post.


I can sort the Intranet Scan output but to do so, I would have wait until the scan completes before displaying anything. As such, it would appear as "Intranet Scan (Sorted)" in the drop down box. If that's what you want, I need to know what to sort it by (ip or name).

 

[lemonadesoda]

Given this console refresh issue, I would suggest using the console to print intermin results, then once finish, CLEAR the console and print sorted.

Re portscan, I just did techpowerup.com:80 and 500ms was the response, whereas it was 130ms on ping.

Given this console refresh issue, I would suggest using the console to print intermin results, then once finish, CLEAR the console and print sorted.

Clearing the console would get rid of all previous tests as well. It also won't be very easy to gather all the feedback for a single output (like Trace Route Advanced does) because it is specifically designed to keep the user in the know. This is why it would have to be a separate item under the drop down list. If you really want it, I can do it but I need to know whether to sort it by name or by address.

Re portscan, I just did techpowerup.com:80 and 500ms was the response, whereas it was 130ms on ping.

Oh, I thought it timed out/didn't work. Yeah, on a few things (everything that uses a monitor thread), 500ms is the bare minimum. The result could have been received in only 140ms but it currently isn't keeping track of individual requests.

 

[lemonadesoda]

1./ OK, I agree with philosophy of console. Keep it as is. Perhaps (not now) once the feature set is finished, consider a second tab for lanscan, and a third tab for traffic lights. That will allow you to implement it differently, whilst keeping console.

2./ OK, thanks for explanation. I did notice that "port open" is different from "port response"... but understand that coding it aint straightforward due to different "protocols" at each port. Perhaps standard :21 and :80 could be implemented though? A traffic light showing that not only is the port open, but is "served".

 

[lemonadesoda]

Can you show a graphic in the console?

A flag after each traceroute IP would be great to see the internet route around the world!

All great ideas but they'll have to wait for NetTool 2.0 if I ever get around to making it. Instead of being console-centric, it will be GUI centric which will allow those features to be added.


Edit: For my future reference: site

 

[Solaris17]

runngin intranet scan immedietly kills the tool on win 7 x64 the other versions worked for me. ill try some of the other things like whois and see if its that setting particularly.

EDIT: just that setting the others work

 

[FordGT90Concept]

It doesn't give you any detailed text? Intranet scan apparently likes bugs.

 

[Solaris17]

It doesn't give you any detailed text?

nope just a stopped working prompt and it shuts down as soon as you hit ok

EDIT::

and thats all she wrote.

 

[FordGT90Concept]

Blah, I'll add more catches...

Edit: Oops, I found a place I intended to put a catch but forgot to...

 

[lemonadesoda]

Solaris, dont click the button. leave the error dialog there and the scan keeps running.

Their app only checks 80, 21, 22, and 443. I can do 80, 21, and 443 with a bit a research but 22 is proprietary.


Edit: the script that actually does the port test is here: http://support.stora.hipserv.com/cpetest


How about a full list of all the non-proprietary port numbers you want checked?

If you need a hand. let me know. I've always enjoyed doin GUIs.

Gotta love exception handling

 

[FordGT90Concept]

If you need a hand. let me know. I've always enjoyed doin GUIs.

I think I will but not ready to commit to 2.0 yet. For sure I would want to make the TraceRoute and Intranet Scan in a custom GUI object (similar to a detailed list view). Port Forward Scan would use the same GUI object as the Intranet Scan.

Gotta love exception handling

Oh the sarcasm.

 

[Solaris17]

Solaris, dont click the button. leave the error dialog there and the scan keeps running.

ill test it but itf thats the case wtf is the point?

 

[FordGT90Concept]

I had an idea last night and implemented it this morning. Hopefully it will fix the Intranet Scan crashes but, no guarentee. As always, details and the file are on the original post.

works great

W00t!

Uploaded 1.4.5. Details on the original post. Thanks to lemonadesoda in helping to debug it.

windows tracert also found more names.

Edit : Using 1.4.5 on a DSL connection

Edit 2 : You need a clear results button, so you can get a blank display area again.

EDIT 3 :
Intranet scan only returns my workstation

Started the intranet scan...
10.10.10.250 epl-infotech.apexepl.com
Scan Complete (4 seconds)

EDIT 4 :
Can you put the version number in the title bar?
Here's how I do it in the main form of my app...

Assembly _Assembly = Assembly.GetEntryAssembly();
AssemblyName _AssemblyName = _Assembly.GetName();
Version _Version = _AssemblyName.Version;

this.Text += "   Version : " + _Version;

Both Trace Route and TR (Advanced) do not display the final destination in the listing.
(e.g. techpowerup)...

Fixed. Tracert might find more names because it has a longer delay.

Edit 2 : You need a clear results button, so you can get a blank display area again.

Added.

EDIT 3 :
Intranet scan only returns my workstation

There's three potential reasons for this:
1) There are no other computers at 10.10.10.#
2) There are other computers but they aren't named.
3) Your computer is IPv4 and the rest are IPv6.

EDIT 4 :
Can you put the version number in the title bar?

Assembly _Assembly = Assembly.GetEntryAssembly();
AssemblyName _AssemblyName = _Assembly.GetName();
Version _Version = _AssemblyName.Version;

this.Text += "   Version : " + _Version;

Fixed and thanks for providing code.


1.4.6 with all the above changes is on the original post.
