Rich Brown Two mentions of InterMapper on Xitim.com

Aurélien has created two useful articles (in French) about InterMapper on the Xitim.com web site. Their (English) titles are:

Simple and effective monitoring of network traffic with Dartware's InterMapper (… Continue

I had a lot of fun at the NANOG48 conference. The presentations were great, many interesting people to speak with, and of course, the Beer 'n Gear session is always a hit. Some of the highlights of the conference for me:

Rich Brown InterMapper at NANOG48

Rich Brown Mibble MIB Browser available

For years, I have been looking for a good tool that I can use myself and recommend for viewing and parsing SNMP MIBs, and for making SNMP queries on devices. There are lots of them out there, but I wanted one that was simple, correct, would run cross-platform so that all Dartware customers could take advantage of the tool, and of course, inexpensive.

Mibble (http://mibble.org) has been evolving over the years. Its author, Per Cederberg has created a Java… Continue

Rich Brown Update: A Regular Expression for IPv6 Addresses

Last week, I posted a regular expression for recognizing whether an IPv6 address has a valid format. Now there's a Javascript implementation that uses the regular expression.

Check out the Interactive IPv6 Address Validator at http://www.intermapper.com/ipv6validator. You can enter an IPv6 address, and the page will indicate whether the entered address has the proper format or not.… Continue

Rich Brown A Regular Expression for IPv6 Addresses

IPv6 addresses are considerably more complicated to parse than the more familiar IPv4 address. Consequently, it's useful to have a standard tool for determining whether they are correctly formatted or well-formed. A while back, Stephen Ryan from Dartware created a regular expression (regex) for validating whether IPv6 addresses are well-formed. We posted the regex as an article A Regular Expression for IPv6 Addresses i… Continue

Christopher L. Sweeney Cloning Scripts Take Advantage of the New HTTP API

InterMapper 5.2 introduces an expanded SDK, including the ability to export many of the files in the InterMapper Settings folder via an HTTP API. We have created two scripts, one for Windows, one for everything else, to make use of the HTTP API to implement cloning of an InterMapper installation. Users are often reluctant to stop their running InterMapper installations for any number of good reasons. Because this cloning operation can be performed while the InterMapper installation being cloned… Continue

Christopher L. Sweeney Returning Values from Command-Line Scripts

In my previous post, I introduced companion scripts and some new macros for working with command-line probes. There is one other interesting features of the sample probes I supplied; the means of displaying values from the companion scripts in the <command-display> section of the probes. Here is the <command-display> section from our python example: <command-display> \b5\Companion Scrip… Continue

Christopher L. Sweeney Companion Scripts and New Macros to Use with Command-Line Probes

Command-line probes have been a feature of InterMapper (IM) for quite some now, allowing users to create a probe out of almost any command that can be executed from a shell. IM 5.2 brings the latest in a series of improvements to make this capability both easier to use and more powerful. A probe writer can now include what we're calling a "companion script" in her command-line probe. Because the script is part of the probe rather than a separate file, there is never any question of what version… Continue

Dartware Webmaster Wanted: One Network Babysitter because I Have Better Things to Do

Not many people become network managers because they like to babysit end-users, or maybe even think about them a lot. Now that networks are the operational foundation for most organizations, not to mention a very significant overhead cost, keeping them running and focused on the job at hand is critical. That means that understanding user behavior is just as important as understanding device behavior. It also means that blocking inappropriate network behavior is falling to the network team. It c… Continue

Dartware Webmaster “Worth a Kilobuck a Month”

Bob Elliot from Soil Moisture Equipment Corp. recently wrote us to say that he has “used InterMapper and InterMapper Flows to monitor bandwidth and locate poorly configured firewalls, routers, and bad cables.” It’s always nice to know that technology is doing the kinds of things it’s supposed to be doing. What really caught my eye was Bob’s next sentence. “InterMapper Flows showed we were only using two thirds of our internet bandwidth. We reconfigured the router. That was worth a kilobuck a mo… Continue

Dartware Webmaster Yes! We're part of the human network

Dartware became an official Cisco Registered Partner in October 2009. It was analogous to getting married after living together for 10 years; that’s how long InterMapper has been monitoring Cisco networks. It’s been a productive relationship. We’ve formed partnerships with Cisco specialists around the world including Boardwalk Communications, Systems DE, and ConnecTIC. Those partners have done a great job explaining how InterMapper keeps watch over Cisco networks and interacts with CiscoWorks.… Continue

Dartware Webmaster What Good is NetFlow?

What is NetFlow? Netflow is protocol that gives information about the senders, receivers, and types of traffic flowing in a network. As traffic passes through a router or switch (called an "exporter" for reasons that will be clear in a moment) on the network, the exporter keeps a cache of information about the packets, including the source and destination address and port, the length of the packet, certain information about its type of service, and more. Periodically, the router or switch fl… Continue
