SMS reception while online

Wanting to be able to use gnokii while I have a connection open with ModemManager, I created the following udev rules in /etc/udev/rules.d/98-pcfe-modem.rules

no, no, not what you think. The Finnish army is just running an exercise.

TPM to feed random number generator

One of the uses of a TPM is to feed /dev/random on your linux box. I will not go into the political implications of TPM.

See also Matt Domsch’s blog.

Those still running RHEL5/CentOS5, be sure to have rng-utils-2.0-4 or later and kernel-2.6.18-238.el5 or later.

Some of the following steps are specific to my HP ProLiant MicroServer, but most will apply to any modern linux and HW (one would prefer the TPM to be an integral part of the motherboard as opposed to a module).

git server setup

For the last decade, I have been using cvs at home to have version control over documents (mostly LaTeX and config files). The original cvs server has been since migrated to a virtual machine.

apcupsd on RHEL5 / CentOS5

While the current Smart-UPS (aka SMT) range of UPS from APC has much fewer variables exposed in a way that is useful for fancy apcupsd usage (you’ll find apcupsd in EPEL), they are still amply sufficient for home use. Basically, the UPS gives an estimated time left at current load and the remaining battery level. At home these are anyway the only two readings I want to trigger scripts on.
