Target: create a test environment for JBoss JAAS authentication using LDAP. Platform: Linux Ubuntu 9.10, JBoss 4.2.2.GA, java 1.6.0_15 Install and configure openldap Installing ldap proved to be the most complicated part as apparently Karmic stripped all ldap configuration from the install so all tutorials found on ubuntu site are useless. Finally I’ve found a thread which described the process. Here are the steps I followed: apt-get remove --purge slapd ldap-utils #remove all my tests apt-get install slapd ldap-utils #install fresh ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/cosine....

Trying to run Apache Directory Studio I’ve found that eclupse crashes in ubuntu karmic 9.10 with the following error: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0x00d64856, pid=8870, tid=3077867296 # # Java VM: Java HotSpot(TM) Client VM (1.5.0_11-b03 mixed mode) # Problematic frame: # C [libpango-1.0.so.0+0x23856] pango_layout_new+0x36 # I’ve tried running it with different java version and with the GDK_NATIVE_WINDOWS=1 with no luck and found the problem unanswered on lot of sites....

Logout messages If you are opening a terminal to a different server or do a su in a terminal then on logout you will be required to enter your password in order to confirm the logout action. Since the polkit-gnome-authorization does not work with the new polkit version which ships with ubuntu and the polkit-auth command does not seems to work either I’ve found after some research that the solution resides in editing the /usr/share/polkit-1/actions/org....

Apparently a cup of tea more bad than good in preventing the AH1N1 flu for my old phone which completely died (drowned) as of the procedure. In conclusion I had to choose fast and I did choose the best of the worst which was the single phone with no opening parts, relatively squared buttons and almost free for my operator. Since I see the phone as a basic tool which does not need much else than the ability to make a call this is most reasonable....

Since my migration to thunderbird I did not had many things to complain but one of the remaining things was the date format. I am expecting to have something like DD/MM/YY or at least DD MMM YYYY. I did not imagined this could be something else than configuration somewhere. Or not… After some digging I found out there is no way to configure the date string but the only way to change the date is to change the locale the application is using....

I’ve also migrated my Acer Aspire One to the new Karmic Koala easy as before using the recommended installation mechanism. One of the things I missed was the SSD specific configuration. This netbook I am using has a very slow SSD drive and I’ve experienced some slowdowns due to the time spent reading and writing the disk. I also wanted to reduce the SSD wear. Here are some steps I have took:...

This ubuntu installation was the bit of fun expected after a few tiresome weeks so I grabbed the cd while still hot and started the installation. As usual the install went smoothly except the fact that I probably mistyped my usual password so I had to modify the /etc/shadow afterward to log in. I was not expecting many changes but there are some graphical changes, the gdm seemed changed and after login I was greeted with a “DISK HAS MANY BAD BLOCKS” message since now there is a tool (palimpsest) which reads the S....

I have been using Evolution since more than 7 years now as my default email client and it has been more than a while that I have been disapointed with it mostly because of how slow it handled new mail. I have assumed that most of the fault was due to spamassasin spam filtering plugin. I tried on numerous occasions to change the default Ubuntu spamassassin and evolution configuration but with little if any results....

This is a very short example I managed to do in not a very long time which does the following things: opens an openoffice draw document modifies a field exports it as ps (using print to file) Ah, and it does that from an external python program. The setup In order to run a python script you need: to set the python path to include the uno lib and start a ooffice server...

Conexant fax-modem configuration In the process of sending a fax in ubuntu on my Dell D820 I did not expected at all that the bigest problem would be getting the modem driver to work. I guess I forgot the old days of linux driver configuration. So, after loosing almost an hour with the linuxant “free” drivers which do not allow fax and the dell free drivers which somehow managed to kill my sound I finally found the solution on ubuntu site which solved the problem and I got both modem and sound back....
