Ubuntu testdrive as a base for a Fedora test

Ubuntu testdrive is AWESOME. In my words, testdrive lets you test the next version of ubuntu in a VM with a single command.

testdrive ultimately just creates a disk image and runs a virtual machine for you, lets you step through the install from the nightly CD, and then lets you continue to run that VM. I decided to use the exactly same disk image and vm command line to testdrive fedora.

  1. Download fedora cd image :
    curl -O http://download.fedoraproject.org/pub/fedora/linux/releases/16/Live/x86_64/Fedora-16-x86_64-Live-Desktop.iso
  2. copy a disk image : cp .cache/testdrive/img/testdrive-??????.img fedora16.img
  3. start the install : kvm -m 2048 -smp 2 -cdrom Fedora-16-x86_64-Live-Desktop.iso -drive file=fedora.img,if=virtio,cache=writeback,index=0,boot=on -usb -usbdevice tablet -net nic,model=virtio,macaddr=DE:AD:BE:EF:A8:CC -net user -soundhw es1370 -vga std -vnc 127.0.0.1:0 -k en-us

Some details:

  • That copy a disk image step could probably be done much better by creating the qcow2 file yourself, but this worked for my immediate need.
  • The differences in the command line from a testdrive command line, on my system, are memory size (1024/2048) and -vga cirrus v. -vga std.

Michigan Loco Ubuntu Global Bug Jam 11.09 for 11.10 is Over

I just got back from the Michigan Loco Ubuntu Global Bug Jam at SRT Solutions in Ann Arbor. I can safely report that Ubuntu 11.10 Oneiric Ocelot is a very nice Ubuntu Linux release which smoothly upgrades from Natty Narwhal. Admittedly, my Natty install didn’t have much customization to it since I had upgraded it from Lucid back in April.

After the upgrade, I worked with John S. Gruber on confirmed a Lernid package that he had put together with some new features. I ran into a nasty desktop couch bug that it seems has been tracked back to Erlang, but luckily, it just meant that my settings weren’t persisted. I was still able to test out all of the Lernid features that John wanted to test. I’ve always been interested in Lernid and I really appreciated the opportunity to help out. I also liked seeing how the –config option worked. Also, the new slideshow command that uses a url to push a slideshow down to clients from the host/instructor is pretty cool. Its an interesting feature and shows where the program might be going in the future.

Once I’d learned enough Lernid, I decided to focus on some things that I wanted to make sure worked. I did an apt-get install mod_mono and monodevelop. I’m extremely excited about this ubuntu release. For the first time in years, Ubuntu is shipping a reasonably modern version of Mono. I was able to get an ASP.NET MVC application running in MonoDevelop in minutes. Note that this includes the download and install of the mono runtime and IDE. To do the same with Visual Studio would take hours. MANY hours if you include installation of VS2010SP1 on top of VS2010. After that, I tried hosting the asp.net mvc app in Apache. I didn’t realize that someone had written an apache config front end. http://go-mono.com/config-mod-mono/ This let me type in a few things and have my application hosted in no time.

I guess that was about it. After we cleared out of the SRT office, I handed off the Amiga 1000 that has been with me for 24 years to our Michigan Loco leader, Craig Maloney. I’m a little sorry to see the Amiga 1000 go, but I am not the type of person who will resurrect it. I think it has found a nice new home with Craig.

OpenWRT 10.03.1-rc2 and Comcast IPv6

After documenting the IPv6 goodness for the old kamikaze release of openwrt, I wanted to play with something a little newer. I also wanted newer iptables so I could play with the tee module.

Some notes:

  • Still no 6rd support on OpenWRT AFAIK
  • rc2 and rc3 are the same for the brcm-2.4 version of Openwrt 10.03.1
  • brcm4700 doesn’t work well at all with my WRT54GL. I think the open source broadcom drivers still aren’t as stable as the proprietary ones that ship with 2.4
  • nearly the same config scripts as the old kamikaze work

Once you flash the router with the firmware you will need to install some extra packages.

  1. opkg update
  2. opkg install ip kmod-ipv6 kmod-sit radvd
  3. paste this code into a new startup script at /etc/init.d/comcast6to4
  4. #!/bin/sh /etc/rc.common

    inetip=`ip -4 addr show dev eth0.1 | awk ‘/inet / {print $2}’ | cut -d/ -f 1`
    inetipspaced=`echo $inetip | tr . ‘ ‘`
    local6prefix=`printf 2002:%02x%02x:%02x%02x $inetipspaced`

    start() {
    ip tunnel add c6to4 mode sit ttl 255 remote any local $inetip
    ip link set c6to4 up
    ip -6 addr add $local6prefix:0::1/64 dev c6to4
    ip -6 addr add $local6prefix:1::1/64 dev br-lan
    ip -6 route add 2000::/3 via ::192.88.99.1 dev c6to4
    sysctl -w net.ipv6.conf.all.forwarding=1 > /dev/null
    cat > /etc/radvd.conf <<EOF
    interface br-lan
    {
    AdvSendAdvert on;
    MinRtrAdvInterval 3;
    MaxRtrAdvInterval 10;
    prefix $local6prefix:1::/64
    {
    AdvOnLink on;
    AdvAutonomous on;
    AdvRouterAddr on;
    AdvValidLifetime 86400;
    AdvPreferredLifetime 86400;
    };
    };
    EOF
    }

    stop() {
      ip tunnel del c6to4
      ip -6 addr del $local6prefix:1::1/64 dev br-lan
    }

  5. pushd /etc/rc.d ; ln –s ../init.d/comcast6to4 S42comcast6to4

Then be glad you have ipv6.

 

This will actually work for ANY provider which uses the standard IPv6 6to4 address of 192.88.99.1, not just Comcast.

Now if only Comcast would open back up their trial so I could join my work to the ipv6 network.

Comcast IPv6 on an old Kamikaze 8.09 Openwrt via 6to4

I’m an openwrt novice, but I know enough about linux and iptables to usually get done what I want. When Comcast announced they were trialing IPv6, I jumped at the opportunity to migration from my trusty Hurricane Electric tunnel to something more direct.

I’m running Kamikaze 8.09.1 brcm-2.4 on my Linksys WRT54GL these instructions probably won’t work elsewhere. I’m guessing that IPv6 is a little different in a 2.6 kernel with a new iptables. If you have very new stuff you should be using 6rd instead of 6to4.

I’m writing this because much of the information I found out there for 6to4 on Linux didn’t work for me, or was only partly correct and I had to piece together suggestions from different sources.

make a script in /etc/rc.d with this content. I called mine comcast6to4

inetip=`ip -4 addr show dev eth0.1 | awk ‘/inet / {print $2}’ | cut -d/ -f 1`
inetipspaced=`echo $inetip | tr . ‘ ‘`
local6prefix=`printf 2002:%02x%02x:%02x%02x $inetipspaced`
ip tunnel add c6to4 mode sit ttl 255 remote any local $inetip
ip link set c6to4 up
ip -6 addr add $local6prefix:0::1/64 dev c6to4
ip -6 addr add $local6prefix:1::1/64 dev br-lan
ip -6 route add 2000::/3 via ::192.88.99.1 dev c6to4

Make your /etc/radvd.conf look like this:

interface br-lan
{
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
prefix $local6prefix:1::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
AdvValidLifetime 86400;
AdvPreferredLifetime 86400;
};
};

That is it. I’m not going to explain it. Read the links below for all of that.

Sorry this isn’t a complete solution. You’ll have to fill in that $local6prefix in radvd.conf yourself.

Outlook 2007 autodiscover for the rest of us

Outlook 2007 has a new feature which is provided to it by default only by Exchange 2007.

I recently thought of giving Outlook a try instead of Windows Live Mail. Of course, the geek in me wanted my Outlook 2007 first run experience to be awesome. I wanted autodiscover to work for me.

It turns out if you read a KB article and a technet article you can figure out that for 99% of POP/IMAP/SMTP installations, placing an autodiscover.xml file at a url of http://myemail.com/autodiscover/autodiscover.xml or at http://autodiscover.myemail.com/autodiscover/autodiscover.xml is all that is needed. The format of the xml is very simple.

<?xml version="1.0" encoding="utf-8"?>
<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">

Do that, and the next time an Outlook2007 client tries to configure itself, it will.

Using the MVPS.ORG Hosts file with ISC Bind

I run my own DNS in our home. You may think this is crazy, but test after test has shown that nearly all ISPs provide substandard DNS to their customers. Even the finest DNS servers are only responsive 95% of the time. With the number of times you use DNS, you could be losing seconds or minutes per day while you wait for timeouts and rerequests.

Mvps.org maintains a list of “known bad domains”. While it is certainly not a replacement for other security measures, its another line of defense. It is another tool in the bag. For more reasons, read their site.

http://www.mvps.org/winhelp2002/hosts.htm

I don’t want to maintain host files on all of my home systems and all of the VMs too, I’d like to just tell my DNS server about these hosts and have it do the right thing.

By combining the downloaded hosts file and using this little boo script to map it into bind config, I have done just that. I use include files to bind. I’ve added a line like this to my /etc/bind/named.conf.local on my ubuntu server

include "/etc/bind/named.conf.mvps";

Then, I’ve added the output of this boo script to the /etc/bind/named.conf.mvps file. Reload bind and everything is done.

import System.IO
for line as string in [line for line in  @/\n|\r\n/.Split( File.OpenText("HOSTS").ReadToEnd() ) if (not line.StartsWith("#") and line!=string.Empty and not line.Contains("localhost"))]:
    fields = @/ +/.Split(line)
    if (fields.Length > 1):
      host = fields[1]
      print "zone \"${host}\" { type master; file \"/etc/bind/db.local\"; };"

Before hand, host resolution looked like this:

$ host ad.a8.net
ad.a8.net has address 203.190.224.60

After reloading bind, it looks like this:

$ host ad.a8.net
ad.a8.net has address 127.0.0.1
ad.a8.net has IPv6 address ::1

ASP.NET via Mono and Apache

In my last post I showed how to build Mono trunk on the latest Ubuntu. I pointed out that I am using it on a “server” install of Ubuntu. I don’t have GTK+ or GTK# installed. So what good is Mono? Its good for hosting ASP.NET web applications.

  1. Configure an apache development environment.
    sudo apt-get install apache2-prefork-dev
  2. Grab my mono-dev-update script and tell it to only do mod_mono
    curl http://jrwren.wrenfam.com/scripts/mono-dev-update
    ./mono-dev-update –m mod_mono
  3. Install the apache module
    pushd /opt/mono/src/mod_mono ; sudo make install ; popd
  4. Enable the apache module
    pushd /etc/apache2/mods-enabled;ln –s ../mod_mono.conf . ; popd
  5. Restart Apache
    sudo /etc/init.d/apache2 restart
  6. Test it
    echo ’<%=DateTime.Now%>’ |sudo tee /var/www/index.aspx
    curl localhost/index.aspx

You should see the current date and time displayed. If you don’t, you have done something wrong.  Note that quotes paste poorly out of wordpress, so you may need to type out some of these commands.

Mono trunk on Ubuntu Jaunty

With the release of Ubuntu 9.04 aka Jaunty later this month, I thought I’d share how to get a current version of Mono on the latest Ubuntu release.

For a number of reasons, Ubuntu always seems to be just a little behind current with its Mono packages. The largest reason IMO is the difficulty in properly packaging Mono for Debian/Ubuntu. I’ve tried and it is not easy.

  1. Make our install a tiny developer environment.
    sudo apt-get install build-essential subversion autoconf libtool bison gettext pkg-config libglib2.0-dev
  2. Install the old Mono 2.0 C# compiler from jaunty so that we can bootstrap the trunk compiler.
    sudo apt-get install mono-mcs
    ln –s /usr/bin/mcs1 /usr/bin/mcs
    This installs enough mono to let the C# compiler run. We will remove this and all its dependencies later.
  3. Fetch the source from SVN. I use a mono-dev-update script to checkout the first time and keep me updated. The script pulls and installs mono, mcs, xsp to /opt/mono on a default ubuntu server install once step 1 above has been performed. To build more parts of mono such as GTK# and MonoDevelop you will need more gtk+ library dependencies.
    sudo mkdir –p /opt/mono/src
    sudo chown $USER /opt/mono /opt/mono/src
    ./mono-dev-update
  4. Remove the bootstrap mcs
    sudo apt-get remove binfmt-support cli-common libmono-corlib1.0-cil libmono-corlib2.0-cil libmono-i18n1.0-cil libmono-i18n2.0-cil libmono-security2.0-cil libmono-system1.0-cil libmono-system2.0-cil libmono0 mono-2.0-gac mono-2.0-runtime mono-common mono-gac mono-jit mono-mcs mono-runtime

The real work is done by the mono-dev-update script. Its a mess of bash script which has served me well for a couple of years now.

I’ll paste the current version of it here, but I’ll also try to keep it up to date for download here.

Windows 7

I received an email from a local Unix/Linux user group email list this morning with a link to this “review” of Windows 7.

http://jhansonxi.blogspot.com/2009/02/linux-users-review-of-windows-7-beta.html 

These are my thoughts.

Having upgraded from Vista to Win7 beta, on 1.5yr old crappy hardware. I can assure you that many of the points in this "review" are absolute lies.

"Windows 7 Setup …Like in XP it is single-task based so that every partition edit is immediately applied while most Linux installers queue up a series of operations and then perform them in a batch"
is an absolute lie. Its as if the reviewer paid no attention to what he was doing.

"The installation and updates took a long time with several reboots"
Exactly the opposite of my experience. After answering all of the questions up front (see previous lies about the installer) on a Friday night, I went to bed and awoke to a rebooted, ready to use Windows 7. There was no login/reboot experience in the install.

The 2nd paragraph of section 2. Installation, the reviewer babbles on about his awesome Linux setup. And while I agree, all of those things are cool, they have nothing to do with a Windows 7 beta review. This gem hidden in that paragraph pretty much sums up the section: "I haven’t tried any of them but …".  Yeah, I can tell.

In section 3. Storage, he does point out some VERY good differences between LVM and RAID setup at install time in Windows 7 versus Linux.

In section 4. Encryption, He continues to trash BitLocker difficulties in installing. Honestly, this is a great detailed comparison of a feature that I’ve never known anyone to use.

In section 5, he fairly says, "I would have to use the superbar a lot to know if I like it better."

in section 6, he makes a bunch of totally irrelevant points like the lack of an office suite. He calls Windows Media Player 12 a "bloated fatware compared to foobar2000, Media Player Classic, and VLC (on Ubuntu I use Rhythmbox). That is cute, except that it is a total lie. WMP12 is awesome. It starts fast. It is still the only media player that does play speed adjustment well. Its only real comparisons on Windows are iTunes, which it smokes, and Winamp. Yes, I still use foobar2000 and Media Player Classic and VLC. Depending on which type of media I am playing back, I use all of the above. But one things that WMP12 is NOT is bloated. It is damn fast.

He continues to point out that DivX MPEG-4 code doesn’t ship with Windows 7. It’s a good true point. WMP doesn’t do a good job of resolving codec problems. Yes, that sucks. Man up and go grab ffdshow from sourceforge. http://ffdshow-tryout.sourceforge.net/ Do not use k-lite codec pack like he suggests. It actually replaces better codecs in the Direct Media codec configuration.

Finally he ends section 6 saying "There are several similar PVRs for Linux" when pointing out Windows Media Center. Seriously??? I think it would be better to just say "I’m stupid and I don’t know what I am talking about." If you have ever setup and run MythTV and compared it to Windows Media Center, you are seriously on drugs. There is no comparison. The ONLY valid comparison is the cost, and the hours you spend on WMC is easily worth the dollars spend on WMC. At least make the freetard "I am free to modify it" argument here. Because as far as functionality, there is no comparison.

In section 7 he confused WOW64 with 32bit and 64bit. I think he thought he was in the 32bit ODBC setup. It is easy to get confused here, because in 64bit windows, there is still a system32 directory, and worse, system32 contains 64bit binaries. There is also a SysWow64 directory, and it contains all the 32bit compatibility binaries. But again, it shows the ignorance of the reviewer. http://msdn.microsoft.com/en-us/magazine/cc300794.aspx

Same section, next paragraph, there is more ignorance, "The Jet engine is the abandoned offspring of the SQL Server team". Anyone even remotely familiar with the history of product groups at Microsoft knows that this is false.

Section 8 talks about UAC, PC Safeguard and parental controls, but does not really say anything.

I have no idea what Section 9 is even doing in a review article. It tries to make some security point and talks about some XDG security concern on Linux and tries to convince you that it is a concern on windows too with lnk files. Read the paragraph and see if you can find the attack vector. I can’t. Its definitely not email, because Windows 7 doesn’t ship with an email client. The suggested download email client, Windows Live Mail, doesn’t let you execute any attachments.

Section 10 starts off saying "I wanted to try recreating the common Linux practice of separating user files from the rest of the OS with /home as a mount point for a separate partition."  Guess what?  Windows isn’t linux. If you want to run Linux, run Linux. Do things the linux way. If you want to run Windows, do things the windows way. Any Windows administrator will tell you, don’t do what you are trying to do! There is this neat thing call the registry which exists in your home directory. Its not going to be portable across windows installs, so don’t bother with that separate home partition. If you want backups, use backups. A separate partition is not getting you anything here. No idea what the next 3 paragraphs have to do with a Windows 7 review.

Section 11 starts off talking about Homegroups, but doesn’t explain them. See the PDC keynote, and then read these two paragraphs and tell me what is wrong here. The 3rd paragraph attempts to describe Libraries. Again, see the PDC video example and compare to this paragraph.  The remainder of this section tries to declare these new features useless. Ok, I know I already use the Library feature. If you don’t like it, don’t use it. I also found another gem, "I think that when a file transfer occurs it’s done under the AlphaUser account and then the ownership is changed on arrival."  You think do you?  Shouldn’t you KNOW?

Still in section 11, I just had to address this comment, "A default install of Ubuntu doesn’t include SMB file sharing although it’s easily enabled by adding Samba." Yes, so true, and resetting every password for all of your users so that they can access the file share. That is fun to do every time, isn’t it? Again, the rest of this paragraph talks all about Ubuntu features, which is strange for a review of Windows 7.

Section 12 is the epilogue which I wish I had read first so that I didn’t waste my time feeling compelled to write this commentary. "Windows 7 beta seemed relatively stable but I wasn’t really installing much or putting it under continuous use." Yes, I can tell. You haven’t used it at all.

"I had a lot more problems with the initial release of Vista." Fair enough, it just happens to be the opposite experience I had. In fact, I have had almost no issues, at all. On what many would consider a more unstable configuration: I upgraded from Vista.

"I did manage to crash Explorer a few times without trying but this is a "beta" which is the equivalent to an "alpha" for most other software projects." WOW, did you use this thing at all? This "beta" is more like an RC3 for most other software project. I installed Win7 a month ago, on my ONLY computer. Not this VM in which you tested it. I use it every day, and it is the ONLY computer I use. I do 100% of all of my work on it.

"This is the reason why many system administrators wait until the first Windows service pack before mass deployments." No they won’t. They will flock to it because its far better than Vista.

"Some readers may get the impression that I’m against commercial software or closed-source." And he proceeds to give reasons why he is objective. I’ll never consider you objective. But I’ll definitely consider you looney and nuts and wacco.

Finally, my own comments: "Reviews" like this aren’t reviews at all. They are comparisons, and they are not valid comparisons. they provide absolutely no value to anyone. They portrait Linux as better. I love Linux. I use Linux daily — in a server environment. Comparisons like this suggest that Linux doesn’t need to improve or play catch up to Windows. I run Windows on my primary use computer laptop, the one I spend 10+ hrs a day at, because it is just plain better. Linux is better in so many ways, ways that this article touts. But Windows is also better in many ways. Depending on how you use your computer determines which ways are most important to you and which is a better choice. I think I just defined pragmatic in there.
