In today's blog, I describe the work I have done on MaraDNS,
link to a new DNS server, explain why I don't like some ultrabooks,
and post an update for BuyVM.
I have gotten an unconfirmed report of Deadwood no longer running after
a couple of days from a friend. While I am unable to recreate this bug, I
take reports like this very seriously. That in mind, I have created
a special debug version of Deadwood which logs all packets Deadwood
To use this debug version of Deadwood, enable the "SHOWPACKET" compile-time
tag (such as with export FLAGS='-Os -DSHOWPACKET' before compiling
For Windows users, I have made a debug build of Deadwood with this flag
set. It has the name "Deadwood-showpacket-20120922.exe"; use this
binary to replace "Deadwood.exe" in Deadwood-3-2-02-win32.zip.
If this bug does not pop up again, I plan on releasing Deadwood 3.2.03
In addition, I have updated the documentation to reflect the fact that Windows
7 and any RHEL6 clone are now the supported OSes for Deadwood, added a note
on Deadwood's use of malloc() (may not work with some embedded systems), as
well as having Deadwood give out a more useful error message if chdir()
fails (it now lets the user know which directory it tried to go to).
Downloads are here:
In today's MaraDNS update, I have updated MaraDNS to use a new GPG key
(see below), use xz instead of bz2 compression for the snapshots, and
have changed the ej2txt tool to use lynx instead of links (since CentOS
6 does not have a package for elinks). Note that Deadwood still uses
bzip2 compression because the old version of msys I recommend people use
doesn't have an xz binary, and won't compile xz.
It can be downloaded here:
MaraDNS GPG sig update
I mentioned in an earlier blog
that I lost
my MaraDNS signing key. Fortunately, I had a really old backup lurking
around down here and was able to recover my signing key.
However, since it has been over a decade, I have created a new MaraDNS signing key which is signed with the
old MaraDNS signing key (the paranoid amoung you can now breathe a
sigh of relief). Barring a compromise of MaraDNS' private key, this
will be the last MaraDNS GPG key I will generate until 2017, around
the same time I update the OS MaraDNS is supported on.
I plan to work on MaraDNS/Deadwood again one day next month, after the 20th,
unless a critical security bug with a CVE number is found.
I just found out about a nice authoritative-only server called "Knot DNS".
Unlike MaraDNS, it has DNSSEC and full zone transfer support.
Why I don't like ultrabooks
While I really like the idea of having a full sized computer the weighs
less, I really don't like the Macbook air clones called "ultrabooks".
The purpose of a laptop is to be able to travel; a laptop that doesn't
use standard parts is a disaster waiting to happen.
To wit: If someone goes wrong with an Ultrabook and I'm
in an exotic country, I am screwed until I can get back
home to get the computer repaired. With my Sandy Bridge Inspiron 14z,
on the other hand, when something goes wrong in an exotic country,
I can go down to the local technology bazaar, pick up a standard part
(a hard disk, in my case), and be working again within 24 hours.
It's just not worth paying $1,000 more for a computer that can not be
repaired in the field -- nor have its memory upgraded -- just to have
something that weighs one pound (1/2 a kilogram) less.
BuyVM finally has regular stock
A few months ago, I complained that BuyVM never
. Jonathan Obrania Tan has let me know that BuyVM has
improved things and, indeed, has stock. Current information about BuyVM's
stock is here:
I need to note that some computers marketed as "Ultrabooks", such as the
Inspiron 14z "Ultrabook", are not really
and use more standard parts.
