The PXE booting in Debian QEMU is broken
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=412010
You need the pxe-* files from http://trac.kju-app.org/browser/trunk/qemu/qemu/pc-bios?rev=106
and put them in /usr/share/qemu
That's all well and good but it uses QEMU's DHCP values for the TFTP server etc. so you need *another* qemu running as the TFTP server and that's not what I want.
So, next step is trying gpxe, so it's off to http://rom-o-matic.net/gpxe/ and got the all-drivers version.
Dammit, I can get 9pxeload working but not bootp so I get boot from ether0 but it can't see 10.0.0.9 from 10.0.2.2
bah

markdown to pdf
pandoc seems interesting. The debian package didn't satisfy its dependencies though.
first up is texlive-latex-base, only 138Mb!
ffs, thats no help, check the page out, it assumes one knows what's going on.
ok, on to htmldoc
sigh, another program that ignores pipes by default HELLO THIS IS UNIX
works good enough, some font embedding issues but not fatal, though to get it in a pipeline you need to give it an output file with .pdf at the end, IDIOTS

DNDR dns caching proxy
Although that sounds dangerously like a DNS server I just couldn't face bind/named.
Curiously it's not an OpenBSD binary package, I wonder if there's a reason for that.
http://sourceforge.net/projects/dnrd/
untar it then
It will proxy DNS from the IP you specifiy on the command line with -s (required) and also serve out entries on a hosts like file : /usr/local/etc/dnrd/master
so for me it's
The -b tells it to round robin the -s entries
ooh why haven't I got round to doing it before, it's fabbo, another one to go in the box marked "essential".
Curiously the master file is only used when -d [1-4] is specified (it doesn't daemonize)
Then because loads of debug is spewing out I ended up installing rc-1.6-readline. I really need to get p9p sorted out.
In the meantime at least I can write sane code.

OpenBSD firewall
Installed 4.6 on my EPIA 5000 fanless & the HD I have in it is too noisy so I want to run it read only.
I've already posted about /etc/pf.conf
I've enabled syslogd on momo to accept udp syslog posts (syslogd -u) which uses UDP 514
Then in the firewall (goo) I've changed /etc/syslog.conf to send all syslog messages to @momo
Easy peasy.
Next is to mount the filesystems read only which I found here.
change fstab to something like this :
do this patch
to make changes later
I got rid of /usr/ports and ended up with about 500Mb of disk used, so I'm well under the 1Gb target. And I've got stuff on there from where I was putting Mercurial on.
