Tower Case with a cheaper faster CPU
I recently wrote about a tower case solution which sliced $500 off the cost. Last night we found an ASUS m/b for a Phenom II which supports ECC. This will be a cheaper faster solution. I will, however, have to buy a NIC. This NIC runs a Realtek chipset. No thanks.

openvpn replay
I’ve started seeing these messages recently: openvpn[2688]: latens.example.org/10.99.36.17:60467 Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #999 ] — see the man page entry for –no-replay and –replay-window for more info or silence this warning with –mute-replay-warnings After reading the man page, I decided to add the following and restart openvpn: replay-window 64 20 We’ll see….
Bacula Configuration
Bacula uses flat text files for configuration. From time to time, people, usually new to the project, ask: why isn’t the configuration in the database? Bacula uses the database to store information about what files were backed up, from what client, and when. This information is useful when you need to know how if you have a copy of a file from last Tuesday before you wrote crap into it but after you

Bacula Retention Periods
Bacula is a backup system with three different retention periods: Volume Job File I set all three to the same value. It is important to note that these values affect only the Catalog. It determines how long a given record is held in the database. For example, if you set File Retention to be 45 days, it means that there are no records in the database for any files backed up in any

Graphing
I have about 14,000 data points collected from backups. I started in Oct 2007, but have not done anything with the data. I’d like your help. I have put the data into a PostgreSQL database and dumped it. The dump is here: http://langille.org/tmp/dlt_stats.sql.gz The table looks like: $ psql dan psql (8.4.2) Type “help” for help. dan=# \d dlt_stats Table “public.dlt_stats” Column | Type | Modifiers ————-+—————————–+——————————————————– id | integer | not null
Big storage
I’m thinking about creating a storage box. One with a lot of disk space. It will be used for backups and stuff. I will continue to backup to tape as well. I’m considering this case, which has 8xSATA hot-swap bays: http://www.newegg.com/Product/Product.aspx?Item=N82E16811192058 If I was buying a RAID card, I’d buy this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16816131002&Tpk=areca%201120 But I may go with ZFS instead of hardware RAID.
Pentabarf – seeing the speakers
Both BSDCan and PGCon use Pentabarf for accepting and reviewing proposals for talks. An issue raised in 2009 highlighted the ability to see the speaker name when review the list of submissions. It is a bit of very useful information. This year, I’ve found out that we can see that vital data. Provided the speaker role has been set to confirmed. I think Pentabarf design assumes that you have created a talk, and

mtx-changer script catches me
NOTE: this problem may not be a problem. After rebooting the system while having the tape library powered up, the problem went away. This may or may not be coincident. Note to self: mtx-changer needs more customization than I thought. Today showed great progress in completing the integration of my tape library into my Bacula system. I have been writing the testing and configuration of supporting tools. I had moved onto a new
