Howto update / change hostname of a system using RHEL 4 in RHN

Today I had to update a system profile in RHN. The system is a RHEL 4 and was added to RHN few years ago and the hostname had changed since then. You can change the system name in RHN but you cannot change the hostname or the ipaddress. I just wanted to share with everyone how to update the RHN profile of a host.

Once your hostname is changed, you just have to execute this command:

up2date --hardware

And voila, you should see the updated hostname on RHN.

Fedora 13 Release party – Québec

Yesterday it was my first release party as an organizer. I was a little bit nervous, because I had to burn few live cd by hand because our official Fedora 13 media are stuck at the custom by UPS. I’ve made a quick presentation assisted by Jean-Francois with the new features of Fedora 13 and videos was playing during people was talking to each other.

Jean-Francois and me arrived at 16h to install the setup and wait for people to come. Around 17h people start to show up and everyone was naturally talking together. I would like to thanks RedHat folks, Michael Lessard and Claude Reeves, for taking time to come and talk with people, Michael come often to other LUG or release party it’s a little bit easier for him, he’s from Québec city.. But Claude is from Montreal so it was really great to see both of them at our event! Thanks again to both of you for your presence!

I think the event was a success, there was around 12-13 persons at the peak, it’s a little bit less than Ubuntu release get here in Québec city, but they are doing release party since few years, so they already have their “returning people”. This is what Jean-Francois and me will focus on the next year, trying to bring more new peoples and new faces to release party and other events!

Here are few pictures I took:

This it the “chat” room! Oops empty pitcher… Need refill!

I’ve installed my laptop with a projector, playing different videos from RedHat YouTube channel I’ve downloaded using youtube-dl. Fedora 13 Launch as you can see Paul Frields on the screen, the famous Truth Happens, How code makes it into RHEL, RedHat MRG demo and a remix of truth happens was playing in a loop on the screen. It was the first time we tried this approach and I think people liked it, the video was playing when people was talking, not too loud so people who want to listen was able to and other people around are able to talk with each other without problem. So this is definitely a “Will do it again”. Plus as you can see on the picture we had a “live usb station” which enabled us to create bootable usb stick for people. This wasn’t a really popular approach, but it’s not really a big setup, so I think we will provide it anyways in the next events.

I was trying to find a new way to provide url to people after a presentation or if they ask us on how to get involved in Fedora project or anything else. I bought a Motorola Milestone few months ago which led me to test few software available on the Android market, and I discovered few bar code reader apps after that I started to read about bar code and “how it worked”. I’ve discovered the possibility of new generation of 2D bar code, so I created few QR Code pointing to Fedora 13 Release notes, How to get involved in Fedora project etc… Plus a QR Code for my contact information. To be honest, this way to share url have made a lot of hand to rise, people was asking how it works etc… It was the first time we used this, so I explained to a lot of person how it worked and how they can probably get a barcode reader for their phone, for yesterday this wasn’t a lot helpful and people didn’t really used it. But I’m pretty sure the next time a lot of people will have downloaded the software needed to read those and they will probably start to use it! I think this is a really good way to make a presentation “Interactive” or to share our contact information, a new kind of business card… And a new way to give people “readable stuff” after the presentation!

Here’s another goodies, the Cheat Cube. Not so helpful for long-time Linux user, but new comer tend to like this one really bad! I wasn’t able to translate the whole thing in french, it’s almost always longer to write something in french… But I’ll try to finish this at least for the next release because people really like this, even if they don’t really use it, they build it and let it on their desk, so it make people talk about Fedora and Linux overall, which is not a bad thing at all! ;)

So this is it for my report of our Fedora 13 Release party. I’m pleased to see that people liked it and we really had good feedback regarding the organisation, we will certainly continue in this way for the next release!

Fedora 13 liveusb-creator problem, can’t download fedora 13 direct from the app.

I’ve installed liveusb-creator prior to a Fedora release party where we will provide people the possibility to install fedora 13 on their usb stick. I didn’t have any live cd iso so I tried to select the “Download Fedora” option, but I was surprised to see that there’s not option to install Fedora 13. So here’s the workaround.

Edit the file /usr/lib/python2.6/site-packages/liveusb/releases.py

# vim /usr/lib/python2.6/site-packages/liveusb/releases.py

and add those line:

{
 'name': 'Fedora 13 (i686)',
 'url': 'http://download.fedora.redhat.com/pub/fedora/linux/releases/13/Live/i686/Fedora-13-i686-Live.iso',
 'sha256': '47ccc37db256387b70857f53a6067e8d50e692c9aa85e45e63e5190c5d1e0942',
 },

 {
 'name': 'Fedora 13 KDE (i686)',
 'url': 'http://download.fedora.redhat.com/pub/fedora/linux/releases/13/Live/i686/Fedora-13-i686-Live-KDE.iso',
 'sha256': '6828c02f2bce4ec3bd1ca488df8662640bf53fe7724913310295a5f5f6502cf8',
 },

 {
 'name': 'Fedora 13 (x86_64)',
 'url': 'http://download.fedora.redhat.com/pub/fedora/linux/releases/13/Live/x86_64/Fedora-13-x86_64-Live.iso',
 'sha256': 'c16923e9c2f04af3609c9534f32ea280e4d2c3af50e704344ccb35090f87065a',
 },

 {
 'name': 'Fedora 13 KDE (x86_64)',
 'url': 'http://download.fedora.redhat.com/pub/fedora/linux/releases/13/Live/x86_64/Fedora-13-x86_64-Live-KDE.iso',
 'sha256': '789d7090d39230f0e9b16ed3276974223c120db3120c48e53fa95a6f1604c650',
 },

Save this and restart liveusb-creator, you should have the option to download Fedora 13. This is a temporary workaround, untill the package get fixed.

For your information, the file has been updated few weeks ago on https://fedorahosted.org/liveusb-creator/browser/liveusb/releases.py but the packages included in Fedora 13 didn’t include this updated file. I’ve submitted the information to the maintainer, the fixed package should come soon.

Update :

This bug is fixed there’s an update for Fedora 13 https://admin.fedoraproject.org/updates/liveusb-creator-3.9.2-1.fc13 and Fedora 12 https://admin.fedoraproject.org/updates/liveusb-creator-3.9.2-1.fc12

Forget about the workaround, you can just update to the lastest version of the package!

Fedora 13 – Evolution problem – Program terminated with signal 6, Aborted. or [abrt] crash in evolution-2.30.1-5.fc13: malloc_consolidate: Process /usr/bin/evolution was killed by signal 11 (SIGSEGV)

After the installation of Fedora13 finished on my laptop. I started to restore files, email accounts etc… Everything worked well untill I restored my evolution backup. Evolution was really unstable, I mean I was away from the keyboard and it was crashing. I was unable to read/write any email..

So I reported a bug on the redhat bugzilla using ABRT the tool in fedora, it detect when something crash and offer you to report the bug and send a backtrace here’s the bug report: https://bugzilla.redhat.com/show_bug.cgi?id=596916

So Evolution was crashing with message like this:

crash  in evolution-2.30.1-5.fc13: malloc_consolidate: Process  /usr/bin/evolution was killed by signal 11 (SIGSEGV)
or
Program terminated with signal 6, Aborted.

I’ve talked with folks from Fedora project and nobody seems to have big problem with Evolution. So I started to look what’s wrong with my install! First, I started evolution in a shell to see the output… Here’s the result I got:

[rpurcell@t61ig ~]$ evolution
(evolution:15208): e-data-server-DEBUG: Loading categories from "/home/rpurcell/.evolution/categories.xml"
(evolution:15208): e-data-server-DEBUG: Loaded 31 categories

Untill here Evolution work fine. And…

bbdb: Buddy list has changed since last sync.
bbdb: Synchronizing buddy list to contacts...
bbdb: Done syncing buddy list to contacts.
*** glibc detected *** evolution: corrupted double-linked list: 0x09c873a0 ***
======= Backtrace: =========
/lib/libc.so.6(+0x7511e1)[0xe851e1]
/lib/libc.so.6(+0x7539b3)[0xe879b3]
/lib/libglib-2.0.so.0(g_free+0x37)[0xd57ff7]
/usr/lib/evolution/2.30/plugins/liborg-gnome-evolution-bbdb.so(+0x454a)[0x2f5c54a]

/lib/libpthread.so.0[0x876919]
/lib/libc.so.6(clone+0x5e)[0xef3e5e]

[...]

I’ve cut some text.. But the important part is that once evolution start to sync the buddy list contact, it crashed.. So I removed the option from the preference menu => Mail preferences => Synchronize contact info and images from Pidgin buddy lists.

And voila! No more crash, Evolution is rock stable…

So if you have the same problem with your evolution on Fedora13, and this option is activated, disable this!! And if this fix your problem please post it on the bug report!

Congratulations on completing Data Center Advanced Technical Specialist AKA ( WTF )

Wow… Did anyone receive this email ?

I passed my CLP 10, few years ago.. And it really look like Novell AGAIN give free certification without even having to pass an exam… OR I’m wrong and this is a scam or and april fool on march 5 ?

Certified Linux Professional 10 ( Exam passed around 2008 at Brainshare)

Few months later I received the Novell Certified Linux Administrator ( Free!!! )

Now Data Center Advanced Technical Specialist!!! ( Free!! ) The date on the certificate is in 2008… ( Did Novell find a way to time travel ? Maybe this is why Eliott and Associate offer nearly 2 billion dollars to buy Novell )

And… it’s not only one it’s two “certification” Data Center Advanced Technical Specialist AND Data Center Technical Specialist.. lol

Having fun on an old computer business who had better time… Priceless

Wow.. Some people are probably happy with this, but to be honest it just prove one thing.

The Novell certification doesn’t mean anything… If you passed the clp exam you probably already know that this certification is not serious at it could be… Even the engineer (  CLE ) is a big “joke”, you can take the “migration course” if you got the CLP from a previous release, and you got the same exam + one question from the engineer exam…

Good job Novell, you are ruining the credibility of your certifications! Sad for people who put their money on those certifications in hope this was going to help them in the business.

I once believed that Novell was going well and can have a great future in the Linux business… Day after day, they prove they don’t understand a lot of things on how to create value from their certificati0ns… And I’m waiting to see where they are going with their Linux distribution…

Anyway, this is really weird, Novell don’t even talk about this certification on their website…

This post is my current understanding of this “email”.  If anyone got more information or if you think I’m wrong and someone can explain this feel free to post a comment…
