OpenNMS and buggy switches

Saturday, July 19th, 2008

One of my evening projects has been setting up OpenNMS to monitor a network primarily comprised of VENDORNAME switches. OpenNMS is being put in to replace a bundle of Nagios, Cacti, Smokeping, and Groundwork Fruity for Nagios configuration management.

Moving from ejabberd’s internal database to postgres

Sunday, March 9th, 2008

During the initial import of data to the {{post id="jabbermetanetnz-has-moved" text="new jabber.meta.net.nz server"}}, I noticed that the roster information failed to be migrated if I was using an ODBC backend - it would just fail entirely.

Restricting ssh password auth by group or shell

Monday, October 30th, 2006

Matt Brown asked if I could think of any way to allow a certain group of users to scp into a host and use a password, while requiring a valid key pair for most other users. Perry suggested a solution to this a while ago, so I sat down and ...
