This post does not show a successful outcome in case that’s what you where hoping for.
I was trying to get OpenBSD bootstrapped using the PXEBoot NIC in a server. I decided to use my Mac which has tftp and bootpd installed. This post is quite in depth and technical so if you are game then read on.

I’ve been hit by a number of Spam comments recently that snuck through the filters.
If you are subscribed to the comments feed, apologies for this.
It turns out that since I moved TechDebug to a VM host, I did not follow my own post and the spam tools where not connecting to Akismet to check the comments. So remember that if you use OpenBSD and the default chroot for Apache, then you need to setup a resolv.conf to allow Apache to resolve hostnames.
It should be all fixed now. If I still get them sneaking through I may have to turn on “logins” to allow commenting. This is my last resort so it’s not in place yet.
Today I upgraded my postgresql database instance on OpenBSD. Did a pg_dumpall, removed the old packages and then added the new ones (latest version 8.1.9 for OpenBSD 4.0 – yes I’m behind).
During the initialisation of the new DB, I got the following error:
creating directory /var/postgresql/data/pg_tblspc ... ok selecting default max_connections ... 10 selecting default shared_buffers ... 50 creating configuration files ... ok creating template1 database in /var/postgresql/data/base/1 ... FATAL: could not create semaphores: No space left on device DETAIL: Failed system call was semget(1, 17, 03600).
The PostgreSQL documentation talks about this extensively. However I don’t want to recompile my kernel away from GENERIC. What else can I do?

The errors that can occur could be either or both of these:
There may be a couple of issues here.

The official OpenBSD announcement states:
We are pleased to announce the official release of OpenBSD 4.2. We remain proud of OpenBSD’s record of more than ten years with only two remote holes in the default install. We dedicate this release to the memory of long-time developer Jun-ichiro “itojun” Itoh Hagino, who focused his life on IPv6 deployment for everyone.
So get to it people, buy a CD and support the project. While you are waiting for your CD to arrive, you can get the release off the mirrors.
I use this OS exclusively for all my servers, firewalls, www, db, dns and it is the quickest to set-up, easiest to administrate (great doco) and the most secure by default of any of the UNIX like operating systems out there.
