Growing a partition on OpenBSD under VMware Workstation 7.1

September 2nd, 2011

I ran out of space on my OpenBSD vm that I use for most everything. So I did the following:

  1. shut off vm
  2. under settings of vm, disk select utilities, expand
  3. grew my partition from 25 GB to 30 GB
  4. saved
  5. booted vm into single user mode
  6. used fdisk -e wd0 to grow the fdisk
  7. used disklabel -E wd0 to grow the last partition (/home)
  8. (yeah I was lucky /home was the last partition and it needed growing)
  9. used growfs /dev/wd0k
  10. fsck -y /dev/wd0k
  11. mount -a
  12. control-d to go into multiuser mode
  13. partition was grown 5 GB's
Hope this helps whomever.

Grandstream GXP-2100 Phonebook Generator

August 12th, 2011

I made a smallish script that produces an .xml file that the grandstream phone can grok for its telephone book. I didn't want to store this on my SIP providers interface because I don't want to reveal the numbers that I have stored other than when I dial them.


	4. EXIT
The script is too simple really. I could stick more effort into it but then it wouldn't be my philosophy of being uber-lazy. Here is the script.


1/6 of my traffic is IPv6 traffic

August 10th, 2011

$ printf "em0\ngif0\n" | while read i ; do netstat -nsbI $i|head -2 ; done
Name    Mtu   Network     Address               Ibytes     Obytes
em0     1500        00:90:0b:19:56:04 36803931395 6075787347
Name    Mtu   Network     Address               Ibytes     Obytes
gif0    1280                          5926981413  823262847
$ uptime
10:31PM  up 103 days,  1:47, 1 user, load averages: 0.50, 0.39, 0.36
The output reveals the Ipv4 and IPv6 interfaces on my home host uranus. gif0 is tunneled over em0 so the 6GB are part of em0's 36GB.


SVPRadio the new Stratford sound

August 7th, 2011

For the past 20 weeks or so a friend and I have been working weekly on a new project. SVPradio is an Internet Radio station for Stratford, Ontario residents and it broadcasts for 6 hours every week (on wednesdays). While my friend DJ Jaz handles the organization and sound I took care of the behind the scenes setup that an Internet Radio station needs. Another friend of mine offered us his server for this which was very nice. Our weekly traffic is still very low as we're not well known yet but word is spreading surely as now the DJ'ing is done from the storefront of Stratford's Compudoc. Here is a picture: In this picture I believe you see DJ Wigs who does a drum-bass and jungle show. All in all the people who make SVPradio happen are great and the shows are always interesting. We always wanted to have SVPradio since our teenager years and the name "SVP" was picked back then as well. What it stands for I'll leave to your imagination as we don't want to reveal that yet. One fitting acronym is "Stratford's very pretty". I'm looking forward to the next 20 weeks and perhaps our listener volume will increase too.


Got new SIP (VOIP) phone

August 6th, 2011

Yesterday, I got my new sip phone. It's a Grandstream GXP 2100. I'm looking forward to making it work, but it works already. The voice clarity is great. Last week I signed up to sipgate.de for a sip account and I'm getting rates of 1 cent per minute in Germany. There is a flatrate for this but I'll have to see if it's worth it. Also I'm unsure whether I'm getting billed for incoming calls, something I'll have to figure out.


Turned on comments

August 5th, 2011

I did a bit of programming today and turned on comments on the blog. You can view them when you click on the articles themselves. No captcha yet though. I hope you find this useful at all, I don't really but I'm willing to take this next big step. Comments are restricted to 8000 bytes or something so keep it short.


snow leopard -> lion

July 30th, 2011

Today we purchased and downloaded Mac OS X Lion (10.7). Everything went smooth. I finally got the Macbook to run in 64 bit mode too. Interesting is that lion has a "pfctl" command. That's new!


leopard -> snow leopard, no problem!

July 24th, 2011

I bought Snow Leopard for my dad yesterday. We installed it on his Mac Book which has a Core 2 Duo processor. No files were lost but the only thing we did was upgrade VMware Fusion from 2.0.8 to 3.1.3 which cost 30.70 euros plus tax. I'm not sure we needed to upgrade the Fusion but it was a surety thing. The intial update after installing Mac OS X 10.6.3 was a 1 GB update to take us to 10.6.8 or something. It was quite a download over the 3 Mbps DSL but it will be nothing compared to the Mac OS X Lion download that we'll be conducting next week. :-).


End of an era, on to the next...

July 22nd, 2011

No, the eagle has not landed. It was the US space shuttle Atlantis that did land at Kennedy Space center a few days ago. There won't be any more space shuttle launches and some people see this as an embarrasment for the US. I don't see it that way but rather have been watching the reports come in from companies such as SpaceX (Falcon rocket, Dragon capsule). The reports are good and I saw a schedule the other day where we'll see a Dragon capsule scheduled for docking with the ISS (International Space Station). Looking back the shuttle has followed and haunted me in my life, I remember the first time I heard about it when the Challenger blew up upon launch. That was the first memory I have of the shuttle. Not exactly a good one. At that time we had immigrated to Canada and I learned that the Canadarm (the shuttles robotic arm) was Canadas contribution to the shuttle. A decade and a half later I immigrated back to Germany and not too soon after that the Columbia disintegrated upon re-entry over Texas. Another haunting memory, but I can say that whenever I migrated around the globe that a shuttle and its crew was lost. My role models were German and Canadian Astronauts. Such as Ulf Merbold, Thomas Reiter, Chris Hadfield, Marc Garneau, Roberta Bondar, are some that come to mind. All of them flew on the shuttle I believe as mission specialists and carried the dream to their respective nations with stories of another state of being (in freefall/in space). So what's next now that the shuttles don't rise anymore? Like I said Space X, Russian Soyuz, European Soyuz and ATV, Chinese, Japanese and Indian space rockets and a slew of other commercial carriers all striving for manned space flight. And since most commercial manned space programs are american it's not an embarrasment but another national hope/treasure. The shuttle was prohibitively expensive and we need the cheaper alternatives that are now up and coming. So with that I say "you did well ol' shuttle fleet, now rest in peace", and I'm thrilled with the future on what's to come.
