IPv6 sensors

Current IPv6 prefix is 2001:660:f183:c001::/64 (mtx-130) 2001:660:3013:3::/64.

There is a demo page.

Unfortunately, these sensors are a mit sensitive. If they are put on a wild network like that of Inria, the tend to shut down after a while.

• 5.4 package for ArchLinux ;
• installation on FreeBSD 5.2.1:

  mehani@tweety:/usr/ports/net-mgmt/net-snmp$ sudo make WITHOUT_PERL=yes install clean

We have a Netgear GSM7312 administrable switch.

AAAAAAAAAAAAAAHHHHHHHHH no PoE !

A shell script using snmpget and rrdtool to collect data and build graphs is in the GForge repository.

And the daily temperature and humidity graph of wherever the sensor looks like so:
