9:43 am - Uverse gone wrong
|
Yesterday morning I woke up to find that my internet service was no longer working. Go U-verse. It seems it went down around 4AM, and wasn't coming back. I called to have them reboot the box since I couldn't log into the router myself, and tried a hard reset. It wasn't working. They scheduled someone to come out that day, and eventually they arrived. After replacing my router, it still wasn't coming back. They replaced parts all over the neighborhood to try and fix things. Eventually he did a full reset, which made service come up for about 30 seconds, then it pulled an update and did not come back. After a bit of back and forth, and a lot of time, they finally got me working. This alone was annoying, it cost me several hours of my time, but it gets much worse.
For a bit of background, I have had my home network set up on 10.13.66/255 since 1998. The reasons that netblock was chosen no longer exist, and haven't in a decade, but I also didn't have much reason to change it. A few years back, I set up a DHCP server, though lots of pieces on my network were still on static addressing (again, no reason to change it at the time). This includes a lot of appliances (squeezeboxes, my aquarium) which don't have keypads for addressing. I have scripts written/used which go by address instead of name, I can tell you the IP of any box in my house as easily as I can tell you the name. It's a practice I have moved away from, but 10+ years of cruft that was working, I didn't bother changing.
The latest firmware for U-verse disables 10. networks from their "default dhcp configuration" Again, no big deal, I don't use their dhcp service since I can't set it for pxe, I use my own. I just go into manual configuration and set the router to 10.13.66.1 and I am done. Except that I can't. Their firmware now states that 10. addresses are not allowed for the router. Now, on top of my hours of downtime because the service wasn't up at all, I have to readdress my entire network. I was given no warning that this was coming, no time to prepare for it, if I wanted things working, I had to either put another router in front of that one, or readdress everything. Thanks again AT&T. I finally have everything working, but I have to ask why such a change would be made, with no notification to customers that it was coming. Why was I given a firmware in the first place that would brick my box? This wasn't the networking, as the reset put it back to 192.168.1 addressing and when it updated, it still bricked.
The last of the mess hit me this morning. I have a script that backs up lots of important things from my file server. I do not keep the backup mounted, just as an extra precaution. The script mounts, backs up, unmounts. I have been doing this for years as well. Laziness prevailed and I never bother to check that the mount was successful before I started the backup. This has worked for years, so I never thought anything of it. Ooops, forgot to readdress the nas frontend for backup, so my / filesystem was full on my mail/file server this morning instead. On the bright side, the script now checks for the mount before doing the backup, and emails me if the mount is unsuccessful.
Today I am hoping for a much less frustrating day.

9:22 pm - Fedora 15 EC2 Test Day Tomorrow
|
This is a little later than originally planned, but the Fedora 15
(yes, Fedora 15 – not a typo) EC2 test day will be on this Thursday
2011-08-04 [1].
Fedora 15 AMIs are available for testing and are listed on the test
day wiki page [1]. The tests are designed to ensure basic functionality
for the AMIs (MTA, httpd, yum etc.).
Since these tests require an Amazon AWS account, we are offering some
compensation (up to US$5) for the first 10 people to go through the EC2
test cases. This will be done on a first come, first served basis -
make sure that you contact rbergeron to verify that you are one of the
10 people or you may not get the credit.
Tim
PS – If you have the means to pay for the EC2 time or a free account,
please use that. We’re just trying to make sure that everyone who wants
to participate can.

4:52 pm - fudcon 2009 Toronto
|
I am back from Toronto and it was much warmer there than Dallas today. Fudcon was a great conference, even though the wireless infrastructure was not up to the task at the hotel or the conference site. Some points of interest:
- Attendance was great, and a massive number of talks were pitched for the barcamp.
- It was nice to get some face time with a number of people I don't normally see, and meet quite a few new people.
- There was a healthy interest in virtualization in general.
- Getting Fedora releases on EC2 is a priority, and there are a number of people excited to both use Fedora on EC2, and help us get it there.
- We have a lot of work to do for F13.
- Cynar (artichoke liqueur) is just as bad as it sounds.
All in all, the event was a success, with a great turn out and discussion. Thanks to those who put in a lot of time and effort to organize things and make sure it ran as smoothly as possible.

11:18 pm - PCI-Express or USB sound card for Linux
|
Dear Lazyweb,
What options are there for a sound card with both analog and digital output, capable of unmolested 96kHz/24bit playback in either PCI-Express or USB, and that are supported with current alsa? A while back I switched my main workstation box. The new box doesn't have PCI slots, so my M-Audio had to go. While the onboard sound card is functional, it just does not compare.

9:16 am - Nice touch, better than a camera phone...
|
Sunday night I went to see The Legendary Pink Dots at the Granada theater (great show!). I don't go to too many shows there, but it is a very nice venue. Since they usually sell tickets direct, they have the email address of everyone who purchased tickets online. This morning I received an email from them with several professional photos from Sunday nights show.
One thing you see at almost all shows these days is people trying to take pictures of the bands with their camera phones. They tend to turn out about as well as you would expect from a camera phone in low light, basically a waste of electrons. It is a very nice change to have the venue send you good quality pictures from the show you attended. Sometimes the little things can go a long way. Maybe other venues will take note.

1:16 pm - Linux Plumbers Conference
|
I am back from Linux Plumbers Conference in Portland last week. I have to say that I was really impressed with the conference. Generally speaking for Linux conferences, the talks are interesting and the hallways conversations are productive. With LPC the talks were really more working sessions, and they were productive in and of themselves. I think a lot came out of LPC and I certainly hope to see the conference continue. A big thanks to all of the organizers and sponsors.
As a result of the sessions and much work outside of the sessions, I think Foresight will see some significant speed up in boot time. As a side effect, certain configurations will "just work" with less hassle than was previously required. I will provide more updates once the plan begins to fall into place.

9:30 pm - Something about the Riverwalk...
|
|
I have been coming to San Antonio for as long as I can remember. Even before there was Sea World, or a reason(s) to "see Shamu", the River Walk was a nice little weekend getaway. Every trip to San Antonio has included dinner on the river at Casa Rio. Tonight we decided to stop by after the day at Sea World with the kids and it was wonderful. Beautiful night out, kids feeding the ducks (tortilla races!), eating delicious Mexican food, sipping a margarita, with the sound of bagpipes in the air... Wait, what?!? Yes, bagpipes. There is a street piper playing on the corner just above Casa Rio, he has been there for at least a year now. It somehow went well with the rest of the night. Next time you find your self in San Antonio, check him out.

8:33 am - Xen is officially in the distro...
|
Many of you have been following the Xen work in rtao, and wondering when Xen support would be officially in rPath Linux... Well, it is officially here! And having this inside the distro makes things much easier. Now most people cooking their groups with [xen,domU] can automatically get a xenified group ready for images, with no extra effort :) If you have your own kernel modules things get a bit more tricky, you will need to build the modules for the xen kernel as well.
Next I will be putting a 2.6.18 based xen kernel in conary.rpath.com@rpl:devel and should have libvirt and virt-manager available in rtao soon.

3:39 pm - Test driving xen
|
A few people have asked about test driving xen as it stands in rtao, these are testing snapshots and the process will become much easier once 3.0.3 is released. In the meantime here are some simple instructions for testing on x86:
Starting from rPath Linux 1:
Verify that you have bridge-utils installed with conary q bridge-utils
If it is not installed, conary update bridge-utils should install it for you
next we add the xen dom0 bits:
conary update kernel=rtao.rpath.org@rpl:1[xen,dom0]
conary update xen=rtao.rpath.org@rpl:1
mkdir /var/lib/xen (this should go away soon, it is a packaging bug that has been fixed but not pushed)
And if running x86:
conary update glibc=rtao.rpath.org@rpl:1[xen]
At this point you can reboot into the xen kernel and should have a running dom0. Verify by running xm list as root
Once that is working you can add your domU instances. As examples I have created a basic network server image and a basic text mode development environment. I will walk you through the setup of these images as domUs below. We have to make a couple of assumptions here, xen needs to know the path to your image file, the amount of memory you wish to give your image and the name for your domU. For these examples we will assume you wish to place your images in /srv/xen/ and you wish to give your domU instances 256MB each.
First we will set up the net-server:
cd /srv/xen/
wget http://www.rpath.com/rbuilder/downloadImage/6769/rtao-domU-netserver-0.95.img.gz
gzip -d rtao-domU-netserver-0.95.img.gz
create a file /etc/xen/netserver with the following content:
name = "netserver"
memory = "256"
disk = [ 'file:/srv/xen/rtao-domU-netserver-0.95.img,xvda,w' ]
vif = [ '' ]
bootloader="/usr/bin/pygrub"
on_reboot = 'restart'
on_crash = 'restart'
now start your new domU nestserver with xm create -c netserver
You should see the domain booting, there is no root password on this image, so create one and use the system as you wish. To exit the virtual console, use ctrl-] To view all running xen domains on the system you can use xm list, and to reattach the console you can use xm console domID where domID is the number in the ID column from xm list
To set up the text development environmnet you would:
cd /srv/xen/
wget http://www.rpath.com/rbuilder/downloadImage/6797/rtao-0.95-x86.img.gz
gzip -d rtao-0.95-x86.img.gz
create a file /etc/xen/netserver with the following content:
name = "textdevel"
memory = "256"
disk = [ 'file:/srv/xen/rtao-0.95-x86.img,xvda,w' ]
vif = [ '' ]
bootloader="/usr/bin/pygrub"
on_reboot = 'restart'
on_crash = 'restart'
now start your new domU development environment with xm create -c textdevel

4:23 am - Kernel 2.6.17 is available...
|
|
For those of you interested in 2.6.17, kernels have been cooked into kernelbits. 'conary update kernel=kernelbits.rpath.org@rpl:1' should give you what you need. As usual, if there are any problems, let me know.

1:02 am - New kernels...
|
|
The 2.6.16.1 kernels have been cooked into conary.rpath.com@rpl:devel for those of you interested. Lots of goodies in these and worth a spin. For the less adventerous, 2.6.15.7 has been cooked into conary.rpath.com@rpl:1. This includes a few bug fixes and one relatively minor security update. Let me know if you run across any issues with either of these kernels.
