Semi OT: Testing Network Connection |
Tue, Sep 18 2007 3:20 AM | Permanent Link |
"Adam H." | Hi Guys,
Does anyone know of some good software that will allow me to test the network connection between two computers (ie, how many dropouts / packet resends / speed / etc). Years ago the network cards I used to use with Lantastic had some DOS software that allowed you to see all this information by booting off a utility CD that came with the NIC. Modern cards don't seem to have this software, and I was wondering if anyone could recommend any software to help diagnose network issues? Thanks Adam. |

And filled with TCP/IP, several protocols etc. jargon. You need to be a network specialist to even understand what the output of these apps try to say. > Modern cards don't seem to have this software, and I was wondering if anyone > could recommend any software to help diagnose network issues? I have used this free Packetyzer tool for years http://www.networkchemistry.com/products/packetyzer.php It shows some complex results that I am not able analyze or utilize. But some of the resulting reports are also quite simple and understandable. > Does anyone know of some good software that will allow me to test the > network connection between two computers (ie, how many dropouts / packet > resends / speed / etc). I could not see, or myself produce any re-sent IP packages. But probably some of those test results will show that dropped package count also. Some years back I used Packetyzer for instance to check the amount of data DBISAM needs to transfer over (slow) lines when used in C/S mode. I noticed that the amount of transferred data is quite significant also in simple Query in C/S mode. But at least not all of this surprising amount is related to DBISAM's C/S design or such. The IP framing just is quite heavy. Even small amounts of data need some 10 kByte IP framing and protocol's internal communicationg around it. Markku Nevalainen |
