Testing throughput with TTCP and Cisco Devices

Posted on October 14, 2011 by

Even if you have been around networking for a while you may have never ran into the TTCP utility. This utility also comes by the name of PCATTCP. It’s a really small command line, data sending, and throughput testing tool. It sends as much data as possible to another remote instance of TTCP. Cisco devices with newer IOS software (11.2 and newer, so a lot of old stuff too by that standard…) and advanced feature sets such as service provider and advanced IP services include this tool, according to the old Cisco documentation I’ve read. This tool was present on … Continue reading →

Passive Sniffing on Windows

Posted on August 24, 2011 by

With Linux you can configure a sniffing only port relatively easy. Put it in promiscuous mode without an IP and sniff away passively. With windows, there is typically always an IP address assigned to an interface. If not statically assigned the interface will search for DHCP and will ultimately end up with an address in the 169 range if no address information is found. Either way there will be information from your machine showing up in a full, unfiltered packet capture. To get around this you will actually want to disable the TCP/IP stack for that interface. If this is … Continue reading →

You will have to setup PHP to run from the CLI for this to work… I also set the execution time really long and could run it from a web page as well.

Mitel 5000 SMDR Script

Posted on July 15, 2011 by

The Mitel 5000 is a great system but the base licensed setup has a bit to be desired as far as reporting is concerned. I wanted to know who was making making and receiving calls and how long they were taking. I found some Mitel documentation on how to enable SMDR on the system and sent ahead and enabled it. After enabling SMDR on the Mitel (and rebooting it) you can run the script below on a Linux machine to collect live call data from the system. The SMDR data exchange is very simple. If you have any issues with … Continue reading →
