Default key repeat rates are always too slow.

sudo echo "keyboard.repeat.del1=200" >> /etc/wsconsctl.conf
sudo echo "keyboard.repeat.deln=50" >> /etc/wsconsctl.conf
echo "xset r rate 200 50" >> $HOME/.xsession

Finally using cvs to manage my HTML source and rsync to keep a synchronized backup of my web page on my home network.

Make sure you're running OpenBSD (duh!).

Install rsync from the ports tree (/usr/ports/net/rsync).

Create a CVS repository:

env CVSROOT=$HOME/cvs cvs init

Download cvsroot.tar.gz and untar it from $HOME/cvs/CVSROOT.

Import your homepage sources:

cd /path/to/homepage/sources
env CVSROOT=$HOME/cvs cvs import -m 'Initial import' ModuleName YourName YourName_YYYY-MMM-DD

where ModuleName is a CVS module name you must assign to your sources. I recommend simply "html".

Now update the rsync command in $HOME/cvs/CVSROOT/loginfo with the appropriate source and destination directories for your homepage sources. This will cause your local source to be synced with your remote homepage files on every commit. Change the -m aaron to -m user@host to have CVS log messages mailed to you. All log messages will accumulate into $HOME/cvs/CVSROOT/ChangeLog.

Some friends and I occasionally play Reaction Quake 3. Since we're spread around the continent now, we also keep in touch via IRC. I wanted public messages on our IRC channel to be broadcast to any current game players. Using ethereal (which happens to have a Quake III Arena decoder), I captured some traffic and discovered how simple the protocol is. So simple, in fact, I easily combined printf(1) and nc(1) to achieve my goal:

/on -public "* #channel *" /exec printf "\\777\\777\\777\\777rcon p4ssw0rd say \\"<$0 $1> $2-\\"" | nc -w 1 -u quake.server.com >/dev/null 2>&1

Setup Samba between my Windows XP box and main OpenBSD workstation.

Make sure you're running OpenBSD (duh!).

Install samba from the ports tree (/usr/ports/net/samba).

Edit configuration files so required daemons will start at boot-time:

sudo echo smbd=YES >> /etc/rc.conf.local
sudo echo nmbd=YES >> /etc/rc.conf.local

and add the following lines to /etc/rc.local:

if [ -f /etc/samba/smb.conf ]; then
	if [ X"${smbd}" = X"YES" -a -x /usr/local/libexec/smbd ]; then
		echo -n ' smbd';    /usr/local/libexec/smbd -D
	fi
	if [ X"${nmbd}" = X"YES" -a -x /usr/local/libexec/nmbd ]; then
		echo -n ' nmbd';    /usr/local/libexec/nmbd -D
	fi
fi

Add a shared user:

sudo useradd -c 'Shared User' -d /home/shared -p shared -s /sbin/nologin shared

Tell samba about the shared user:

smbpasswd -a shared

Now create a usable /etc/samba/smb.conf configuration file. Here's an example:

server string = Barrington
workgroup = SHARED
encrypt passwords = yes
interfaces = 192.168.0.251/32
dns proxy = no

# A publicly accessible directory, but read only, except for people in
# the "staff" group
[mp3]
   comment = MP3 Share
   path = /home/shared/mp3
   public = yes
   writable = no
   printable = no

Start samba:

sudo /usr/local/libexec/smbd -D
sudo /usr/local/libexec/nmbd -D

In Windows XP, go to Control Panel -> System -> Computer Name and click on the Change... button. Make sure Workgroup is selected and enter "SHARED" into the text field.

Finally, to access the new share, open Windows Explorer, click on My Network Places, then click View Workgroup Computers. You should see your OpenBSD box in the list. If it's not there, wait a few minutes, and try refresh.

Compile Mozilla 1.2.1 for OpenBSD 3.2-current.

Install OpenBSD i386 snapshot from 12/26/2002 or later (for gcc/propolice bugfix).

Download Mozilla source from ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla1.2.1/src/mozilla-source-1.2.1.tar.gz and untar into your homedir.

Apply the following patch to the sources:

Run ./configure and compile with gmake. If the configure script complains about missing packages, install them from ports (i.e., you'll need gtk, orbit, etc).

When complete, use the following script to run from your homedir:

#!/bin/sh
cd ~/mozilla
if [ -f dist/bin/components/compreg.dat ]; then
        rm dist/bin/components/compreg.dat
fi
export LD_LIBRARY_PATH=~/mozilla/dist/lib
