There is a issue with the Citrix Client on Linux with some certificates providers. If the client doesn’t recognize the certificate, you get this error when you try to launch an app:

“You have chosen not to trust the “CA PROVIDER” the issuer of the server security certificate”

and then the app won’t start. It’s likely because the CA hierarchy is not correct. The solution to go round this issue is to place the the missing bits (the CROSS certificate and the SSL ICA certificate) under the certificate folder of the client situated here:

/usr/lib/ICAClient/keystore/cacerts

Now it should be all sorted!

I was looking at a way to change the IP address of a HP Web JetAdmin server and if it was possible to create ACLs based on Active Directory users when I come across a website presenting article to “hack” your network printer. It’s basically more of a compilation of useful things to know than hacking properly said but it could be quite useful and sometime fun. Anyway, it’s worth to check it out.

On the other site, if for any reason you need to change the IP address of your web JetAdmin server, here is how to do it:

You first need to backup your settings. You can find the backup tool here if WJA is installed on the default path:

c:\Program Files\Hewlett-Packard\HP Web Jetadmin 10\WJABackupRestore

note that if you have a non standard install path, you will have to edit the location of ’set OSQL’ inside the script.

Once the backup is finished, open the file ‘HP.Imaging.Wjp.Core.WebServer.config.xml‘ in the Settings\WjaService\config folder and replace the IP address with the new one.

you should find something like that:

<property name=”HostIPv4Address”>
<type>HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString</type>
<value>your.IP.address</value>
</property>

Run the restore script and allow it to overwrite the existing database.

You should now have a fully working HP Web JetAdmin!

This post is for my French fellow as it’s about a french web TV so I’ll continue in French :)

Si vous aimez vous tenir informés sur le monde de l’open source et que vous voulez quelque chose d’un peu plus interactif qu’un site comme Linuxfr, je vous conseil de jetter un oeuil sur http://www.intelli-n.tv/

Ce site assez recement demarré est plein d’info sur différents sujets, en general pas trop technique, toujours interessants :)

Il y a un JT chaque jours et bien d’autre chose a voire comme parole d’expers, …

le contenue est plutot orienté metier que geeky techy mais encore une fois, sa vaut definitivement d’aller getter un oeuil!

We are in a process to replace our Internet security infrastructure. It’s currently based on windows 2000 proxy server and Websense web filter 6.3 to “monitor” and control users internet browsing. For those who don’t know Websense, it’s on of the leader in internet security solutions. It’s main product is Websense security gateway, which provides a complete infrastructure to manage internet web access. We always had trouble with Websense filter, especially the reporting tool as it’s not really reliable… And as you would expect in a project to replace 3 proxy servers and all the stuff we use around, it’s not straightforward. First of all, the gateway can be installed only on Linux Red Hat 4.5 (yes, 4.5 not 5.4!) We thought it was a minimum requirement but it’s actually not! if everything seems to work fine, you can’t download the database because you have the wrong kernel (can’t see the relation between a download and a kernel though :p ) So it basically means that something on the code check that you have the specific kernel… I don;t really understand but fair enough and let’s go for a RH4.5!

They also told us that their support for MySQL was crap so they highly recommend to use MSSQL! Great! what if you install MySQL then? you’re not supported ? If it is so bad, why do they even give the customer the possibility to choose? And why someone from the company dare to say that their support of this database is bad? It’s not really a plus for the company… You tend to hide your weakness, not to expose them :) but whatever…

But the main problem we have now is that you can’t stream a video with real player! I don’t know if it’s a problem that affect more than this type of stream but it’s not cool… We raised a ticket with them regarding this issue and as the could reproduce it every time, they stated that it was a bug. They’ve been investigating the bug for more than two weeks now and they apparently haven’t figured out why this is happening!!!

Therefore, as long as the bug is not fixed, the project is frozen and we can’t go live ^_^. I love bugs. I hope they are going to come with a nicer answer than with the last we had with the reporting system! (not supported anymore because of too much bug… Thanks I noticed ^_^)

Sounds like it’s going to be a lot of  fun to support this system at work :p

Welcome to my brand new blog. I’ll try to talk about IT in general, but probably more specially about Linux, and VMware.

I’ve been using Linux as main OS for 3 years, maybe a bit more. Ubuntu most of the time for the desktop. Debian or Red Hat for servers. I’m an open source fellow, and even when I have to use windows, I try to stick to my ideas, always open source first :D

VMware as a second subjet might be a bit surprising after what you’ve just read, as it’s not an open source product and there is Xen to compete against it. Yes, but I think VMware is a much more complete product. It not for no reason that they are leader on the virtualization market!

Anyway, as I have to work on an heterogeneous environment, I’ll probably also post about Windows and some other things. So why “Linux os for me” as a name for this blog then? If you don’t just speak about Linux… Just because I like the pun :D Linux is an OS, but you could read it “Linux is for me” as well. And this is my favourite subject anyway…

Enjoy!!!
