Linux

I have a QNAP TS-453A NAS with 4 6TB disks configured as a RAID5 storage pool. Currently with firmware 4.4.2.1262.

Yesterday I discovered that one of the disks (disk 3) had failed, and that the storage pool was in a "Degraded" state.

I quickly got a new disk. The old disk was a WD Red 6TB WD60EFRX, the new one is a WD Red 6TB  WD60AFEX. I hot-swapped the disks. According to the documentation, the new disk should be detected automatically, and the storage pool should automatically start rebuilding ("Rebuilding" state). But nothing happened.

I have implemented whitelisting of sender addresses and domains in SQLgrey. Now you can list senders that should never be greylisted, and you can let outgoing email automatically update the whitelist.

One day I started experimenting with DKIM, and configuring my Postfix server to add DKIM signatures to my outgoing email. I quickly found dkimproxy, which is a content-filter for Postfix that implements DKIM.

I have built rpms of clamav 0.97.6 for Fedora 8, by backporting clamav-0.93-1.fc9.src.rpm from Fedora 9 and modifying it to build with clamav-0.97.6.tar.gz.
