All that’s happening around here…

Italy & More

Speak Change of plans, I’ll be pesenting after all. Better yet, I actually intend to show the latest development snapshot live! So don’t miss out if you can make it (details in previous post :)

NeDi News

Speak With the CeBIT coming up next month I can offer some free tickets! Contact me in the forum, via mail or Google+, if you’re interested in visiting me and my sponsor. I’ll be with Sector Nord at Gemeinschaftsstand-Exclusiv, Halle 6 (A50) from Monday thru Wednesday.

The week after on March 15, Michael Schwartzkopff gives a speech at the Chemnitzer Linuxtage.

Last but not least Alain Mowat from SCRT informed me about a vulnerability in the function plotter. However this module is disabled by default and I’m going to remove it completely from upcoming versions. You can simply delete Other-Plot.php and inc/graph.php to be on the safe side…

Stay tuned as I have some great announcements to make very soon!

NeDi 1.0.9 is here!

Announcement After a shorter than usual development cycle, a new release has arrived. The changes are listed in the README.txt, which is displayed after upgrading via webgui. Many new enhancements like Postgres backend, interactive maps and new reports made it in. Find some pictures at Google+ for more information. You can contact me for professional consulting and support now…

After 4 weeks off…

AnnouncementI’ve enjoyed beautiful beaches in the Maledives for 4 weeks indeed!

However I’ve also learned from a rather annoying experience and turned the whole thing into something useful. I presented this at the last ETH security talk…

I’m going to use the holiday period the finish nedi 1.0.9 and spend time with the family (of course). I wish the best to all of you and want to thank the community for the continued support and trust!

Best Regards

Final RC is here

Development I proudly present nedi-321 – the final release candidate for the nedi-1.0.9 version. Many changes and improvements made it in, so the final testing needs to be thorough!

Have a close look at the discovery (start without -v). Check for warnings on failed SNMP access (uppercase letters followed by a lowercase one). You can finetune this, by adding a retry value after timeout in nedi.conf. The discovery itself should come across a lot cleaner than before:

Building nodes
DDDDDDDDDDDDDDDDD done
END :Took 0 minutes

If you want to see more debug information add “x” to notify in nedi.conf. Read here, what it does…

Last but not least, you’ll find many changes in the GUI! Just look through the README and keep exploring! A highlight besides piecharts in reports and more charts in Monitoring-Timeline, definitely is the new D3js visualization in Topology-Map! Just start with changing the format from “png” to “json”. Use flat-mode, if you don’t have compatible SNMP location strings. Then play with Node-Type…

In the month of December you’ll be redirected to Other-Invoice instead of User-Profile. If I can raise enough funds this way, I promise to take NeDi to the next level! Bookmarked links won’t be affected, though.

Website Updated

MaintenanceI didn’t exactly plan it like that, but here is the new home of NeDi, sexier than ever ;) I decided to delete all files and reinstall everything, after some individuals (even worse than spammers) exploited a vulnerability in PHP. However I’ve learned a lot about forensic apache log analysis and even wrote a little Perl script, that allowed me to track back what exactly happened…

Things are looking much better on the NeDi front! I need to cleanup some code and will make the final release candidate for 1.0.9 available to the public in the coming days!

Development News

DevelopmentThe SNAG event in Hamburg was very interesting and I’ve received a lot of positive feedback.

The new version (oh9) is coming around nicely and I’m glad to announce, that Postgres support is almost complete. This means NeDi will no longer depend on mysql, but of course still can be used with it…

I’ve added a NeDi Google+ page linked to the Youtube channel for easier sharing, so please make use of them to spread the word :) I’m gonna post quick updates there rather than in the forum to reach a broader audience!

Summerbreak

d3js animated mapIt’s been exciting to enjoy summer at its best! Coding in the sun, just is more fun ;) I replaced some old map features (no one was really using anyway), with stuff like animated maps using the powerful d3js library and OSM support (even caching maps), with weather information from OWM (in case you’re wondering why you can’t reach that remote site anymore). Beautiful Chart.js visualization complete the picture for various reports and interface statistics at a glance. I’ve not just been working on eye-candy, but also added info on unused access ports and whether a configuration has been saved after changing along its backup status in the DB.

Weather in Topology-TableNow, you can add nodes to monitoring and gain control over syslog behaviour in addition. With the upcoming feature to manually add devices, this is not really necessary anymore. Removing monitoring support for nodes altogether, would simplify my life and streamline NeDi a great deal. Please help me in making a decision on how nodes should be treated in the future, by voting in this poll.
