If you frequently come here to read this blog you may have noticed that the graphics changed. I spontaneously did this today and I like it. The main graphic is a triangle with a star (the sun) in its centroid all in the european colours. The star has nine points with three points to every side of the triangle. I made two pictures, one with a black background and one with a white background. The picture is supposed to represent the union between solarscale.de and centroid.eu which have been the same website under the two different names for a while now.

Airport Extreme JetDirect port has changed?

April 16th, 2010

I've been googling a bit now to find out why the port 9100 on my parents airport extreme didn't work for JetDirect printing. I've found this. Apparently the port changed on some firmware updates from 9100 to 9101. I'll give this a shot tomorrow when I visit, as Rendevous printing with an old 10.3.9 Mac Os X doesn't seem to work right on the setup that I got there.

Generally I'd portscan but nmap didn't compile on such an old version of Mac OS X.

Update: it's true it is on port 9101, although Mac OS X 10.3.9 doesn't have an option to configure the port right, I had to go into the cups webmanagement at localhost port 631 to make it work. Mac OS X 10.5.x (my dads macbook) worked with configuring the jetdirect port to 9101 in the apple config system.

Making X11 resolution work right with vmware guests (1920x1080)

April 15th, 2010

Generally I'm easy going. That means that when something is misconfigured, I don't care too much and find workarounds. For a while anyways. So to give you an example I had my new Kubuntu start up with a 800x600 screen under vmware and it didn't change resolution until I went into the system settings and clicked on the Display config, it then resized upon opening the program. Similarily in OpenBSD the resolution was 1024x768 or such so that there was "wings" of blackness on either side of my widescreen monitor.

All this I lived with for several month, but since I use OpenBSD as my main desktop it finally boiled down to me having to fix it. I googled. First hit had my answer. Someone said to use the program "gtf" to generate a Modeline for my monitor and stick it into the screen section. I tried that and it didn't work. They were wrong in that it was the "monitor" section it should have been put. Once I did that and having examined the /var/log/Xorg.0.log I noticed that my horizontal syncrate wasn't accepted. So I bumped it up to 90.0 and it finally worked. I want to share my Kubuntu /etc/X11/xorg.conf file with you, and very similar modifications also worked with OpenBSD, so here is:

Section "Device"
        Identifier      "Configured Video Device"
        Driver          "vmware"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"

        HorizSync       31.5 - 90.0
        VertRefresh     40 - 150

        # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
        Modeline "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 
1118  -HSync +Vsync

EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        DefaultDepth    24

        Subsection "Display"
                Depth 24
                Modes "1920x1080_60.00"
                Viewport 0 0 
        EndSubsection
EndSection

Hope it can be useful for others. Oh yeah, if you're curious why I run both Kubuntu and OpenBSD as desktops it's this: When I require flash I switch to Kubuntu, otherwise I do everything in OpenBSD. Most of the google tech talks I watch are watched with Linux.

Nothing to report

April 9th, 2010

I don't like putting 2 hackepedias back to back. Oh yeah I relased beta_5 of wildcarddnsd and a patch to that on sourceforge, that's what I've been doing mainly these past few days.

WildcardDNSd, new features

March 27th, 2010

In the last 2 weeks or so Wildcarddnsd has gotten 2 major features. TXT RR support is one (which I did today) and NS delegations work now. Before they weren't working right. Also I extended the region support to IPv6 which was interesting.

Although these features are in HEAD I'm reluctant to CVS tag for BETA_5. It's too close still to the last BETA_4 tag. Perhaps in a month, I can consider this.

Clear skies, no camera

March 24th, 2010

Well. We had clear skies tonight but I had no chance of making a picture of the southern sky. Also looking out I cannot make out the constellation Leo with the bare eyes. Too much LP (light pollution). However as you can see I have the Xephem program doing magical things. In the southern sky at 11PM tonight one should see Mars and Saturn as well as the Moon (further up). Xephem is really a great astronomy program.
