How to Monitor Network Packet Loss

June 10th, 2014 No comments

When data is transmitting over computer network, one or more packets may fail to reach their destinations, and this is packet loss.

Packet loss can be caused by multiple factors including network congestion, the performance or policy of networking devices, and networking hardware faults.

Download Capsa

To test the packet loss rate, you can use Colasoft Ping Tool:

To monitor network packet loss to thereby monitor the quality of the network, you can use Colasoft Capsa.

There is a Diagnosis view on Capsa.

  1. If you have a diagnosis event of TCP Retransmission, it means there is maybe packet loss on the network (according to the transmission policy based on TCP/IP protocols, the packet will be retransmitted if it is lost).

  2. Then, double-click the event on the Details pane:

  3. A window pops up to show the decoding information. According to the Sequence number and the Acknowledge number, it is determined that there is packet loss on the network.

Packet loss is not always a bad thing. It depends on the type of data being sent. For example, when a text document is transmitted, it is unacceptable to drop a single packet. But, for VoIP (Voice over IP) traffic, it is acceptable to drop one or two packets every now and then.

How to Capture Wireless Network Traffic

June 9th, 2014 No comments

As an innovative and high quality network analysis solution, Capsa network analyzer is not only designed to monitor and analyze wired network traffic, but also for wireless LAN traffic, including 802.11 a/b/g/n networks.

The Enterprise Edition of Capsa network analyzer provides you the capability of wireless network capturing and encrypted wireless data decoding. No matter which encryption type an AP uses, all WEP, WPA and even the hardest WPA2 wireless traffic can be decrypted with the pre-specified security key. Additionally you do not have to figure out the encryption type of an AP, Capsa identifies and matches the encryption type of keys automatically.

Download Capsa

We all know that users have to connect to an AP (Access Point) in order to access wireless network; users must have a wireless network adapter in order to access a wireless AP. Therefore, to capture wireless traffic, we use Capsa to monitor a wireless network adapter.

Please follow steps below to monitor and capture the traffic of wireless network.

1. On the Start Page, choose a wireless network adapter. Once a wireless network adapter is enabled, Capsa automatically detects and displays all available APs.

2. Choose an AP that you want to monitor, and if the AP is encrypted, enter the password for it. Once an encrypted AP is enabled, a dialog box pops up to let you enter the key. If the dialog box doesn’t pop up, just double-click the AP to open the box.

3. Click Start to start monitoring; or if you want to set up alarms, capture filters, packet auto-saving, choose a proper network profile and a proper analysis profile and then click Start to start monitoring

  • Once a wireless network adapter is used for capturing packets, it cannot be used for accessing the network anymore.
  • If you enter the wrong key for an AP, the analysis project will run as well but it will not decode any packets.
  • One analysis project can monitor multiple APs at a time, but the APs must be at the same channel.

 To decode and analyze wireless traffic, you are recommended to:

  • Make sure the password for monitored AP is correct.
  • Be close enough to the wireless router (signal source) to thereby capture all packets.
  • Monitor the AP before other hosts access the network to thereby capture EAPOL handshake packets.

Colasoft nChronos How-to: How to Display IP Addresses as Host Names

May 28th, 2014 No comments

How to Display IP Addresses as Host Names

If you use nChronos to monitor traffic on a core switch you will see lots of internal IP addresses, and also the Internet IP addresses. You can find that most of the Internet IP addresses are shown as their domain name, such as www.colasoft.com, and www.google.com, etc. Wouldn’t it be great if nChronos shows host names of our local machines, because they are much easier to understand, rather than just IP addresses? This tips article will show you how to use Name Table to display IP and MAC addresses as host names.

Download Capsa

Suppose that there is a user, Steve, whose laptop has this IP address, 192.168.8.25, and you want nChronos to show his IP address as the text – Steve’s Laptop. First you run nChronos Console, connect to the server, right-click on the server name, and clickSettings from the context menu. Then select Name Table on the Server Settingswindow.

Then click the Add… button on the right side, you see a new dialog box. On this dialog box, input the IP address, 192.168.8.25, and input Steve’s Laptop in the Alias textbox. You can even choose the font color for this name if you like. Then click OK.

There is a little trick that you can input the IP address and click Resolve Address to find the host name automatically. It uses NetBIOS protocol and it’s able to retrieve the host name from that system. Or you can click Resolve Name button to translate the host name into IP address.

Download Capsa

The names you add will be saved on nChronos server, so you see them from every nChronos console. And besides IP addresses, you can still give names to MAC addresses, only that you cannot use name resolution function for MAC addresses.

You’ll find that you cannot click the Edit and Delete buttons sometimes. That’s because you have link window open, and the window uses the names for display. So it doesn’t allow any changes to the names if a link window is open. So you just close all link windows of that nChronos server, and you’ll find the buttons are clickable now.
