5 – 9 December packed the first advent with the release of InGraph and a Gude plugin, tips on email address verification and automatic IPv6 configuration.
Following the excitement from the preview made at the OSMC, Gunnar released inGraph for download. Aside from generating informative graphs of Nagios/Icinga performance data, inGraph also features a cronk for seamless integration into Icinga Web. This includes a preview graph accessible from the service view, which displays information in line with user rights and permissions. In the standalone version too, graphs can be customized with the help of templates, and graphs from various hosts and services can be combined for comparison. InGraph comes with a check plugin to also offer trending of certain services. For more information see the inGraph project wiki.
On the topic of releases, Birger shared a new check plugin for Gude sensors to go with the new temperature, humidity and current/voltage sensors in store. These include the expert net control 2101/2151 and expert net control 2i2o 2100/2150, with the expert sensor box 7212 and Gude conductors with measurement still to come. The check_gude.pl for Nagios/Icinga can be found in our plugins area.
Per Georg, the same new devices from Gude featured in the hardware exhibition at the OSMC, alongside the Multitech iSMS, Nagios USB traffic light and Starface VoIP appliance for voice alerts.
From Managed Services, Sebastian explained Domain Keys Identified mail for the verification of sender email addresses, contrasting it to the Sender Policy Framework (SPF). The latter creates a record in the DNS zone file with the allowed MTA mail server IP addresses for the receiving server to verify the domain against. Domain Keys Identified mail however, uses a private key generated signature in each email’s header, which can be verified against a corresponding key located in the DNS zone.
Carsten then offered his tip for automatic IPv6 configuration with the help of radvd. Making the most of the IPv6 stateless address auto configuration feature, he gave an example of an radvd configuration on site local addresses. He noted however, that stateless address auto configuration is currently only possible on a DHCPv6 server.
To end the week with some festive cheer, Bernd declared the world’s best shashlik to be found at the Nuremberg Christmas market.
