KeePassX 2.0 On Redhat 6 / Cent OS 6 / OL6



I'm sure we all know the virtues of long, complex and unrememberable passwords and the need for a tool to store them. My favourite has been KeePass, with a shared database on a cloud drive.

KeePassX has long been around for native Linux support, but hasn't been compatibility with the KeePass 2 (Professional Edition) database format kdbx. Well the excellent authors have release KeePassX 2.0 which is a rewrite with kdbx support.  Currently only available as source code, the following instructions will help you to compile and install on Redhat 6/ CentOS 6 /Oracle Linux 6.

Required packages
$ sudo yum install cmake gcc-c++ qt-devel qt libgcrypt libgcrypt-devel libXtst libXtst-devel

NOTE* GIT version https://github.com/keepassx/keepassx uses QT5 plus other packages.

Download source
$ wget https://www.keepassx.org/releases/2.0/keepassx-2.0.tar.gz
$ tar zxvf keepassx-2.0.tar.gz
$ cd keepassx-2.0

Create UNIX Makefiles
$ cmake  -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_VERBOSE_MAKEFILE=ON -DWITH_GUI_TESTS=ON 

Compile and install
$ make
$ sudo make install

Execute
$ /usr/local/bin/keepassx

Solaris Leap second - Time well spent



Stayed on line for the extra second 01:00BST.

Glad to say all Solaris system good so far.


Solaris 11.2 Latest SRU - NTPv4 Slew mode
Jul  1 01:00:01 sol11-2 ntpd[659]: [ID 702911 daemon.notice] Positive leap second, expect slowdown slew soon. System clock will be inaccurate until it finishes.

Solaris 11.1 - NTPv4 Slew mode (bug doesn't handle leap second correctly)
Jul  1 01:00:00 sol11-1 ntpd[3459]: [ID 702911 daemon.notice] Inserting positive leap second.

25 years as an IT Professional.

25 years today I started work at WTL PLC. Then known as CEC, which was Data General and Wang broker. I came on board in 1989 at the start of the Unix technical workstation revolution, "Power to the Desktop". Along came Apollo's running Aegis/Domain OS and Sun MicroSystems Sun-3 range with SunOS 3. Installing and patching from QIC tape was the highlight of my day!

A lot of things have changed over the years in IT, which is itself is the catalyst that has kept me challenged, motivated and passionate about delivering solutions to customers.

As the longest serving employee at WTL I've seen a few people come and go, but the core people and values haven't. The technical team around me, are dedicated to the customers challenges and issues and continue to make my life easier. Equally the WTL sales team, driven commitment in finding outstanding projects, to which the WTL technical team can deliver the foremost technology with latest servers, storage, software and networks.

Thanks to all customers and colleagues(friends) for all your support over the years.

A Multitude of Putty Sessions


Many hands may light work, doesn't really work with in IT. I usually look for consistency and reproducible results. So let change this for one hand and many windows make light work!

Come across a nice tool PuttyCS for Windows people which did just the job.


In the Solaris world I would use Sun's Cluster Console on CDE, but other seem to favour Cluster SSH or PSSH.

I would be amiss to say, a better answer to issues above is to automate and use confguration management tools such as Chef and Puppet.

Solaris 11 Locale en_GB.UTF-8 / en_GB.ISO8859-1 / en_GB.ISO8859-15


When you install Solaris 11/11 from standard text installer cdrom, the en_GB-UTF-8 locales are not installed, even if you select British locales on install.

To make sure packages are have the correct localisation, IPS uses facet as a localisation personality.
$ pkg facet
FACETS VALUE
facet.locale.pt_BR True
facet.locale.es_ES True
facet.locale.en_US True
facet.locale.zh_TW True
facet.locale.zh_CN True
facet.locale.de_DE True
facet.locale.fr_FR True
facet.locale.it_IT True
facet.locale.ko_* True
facet.locale.ja_* True
facet.locale.es True
facet.locale.de True
facet.locale.zh True
facet.locale.ko True
facet.locale.it True
facet.locale.pt True
facet.locale.fr True
facet.locale.en True
facet.locale.ja True
facet.locale.* False



As you can see no en_GB is described and "facet.locale.* False" is a deny everything else rule. So let change this. I'm assuming you have a Solaris 11 repository already configured. Iinstall en_GB packages/files and creates a backup boot environment.

$ sudo pkg change-facet 'facet.locale.en_GB=True'

            Packages to update: 463      
       Create boot environment:  No
Create backup boot environment: Yes


PHASE                                          ITEMS
Image State Update Phase                         2/2 

Now lets make the en_GB.UTF-8 the default locale. Previously in Solaris 10 we would edit /etc/default/init. But as with many thing in Solaris 11 this has moved to SMF and /etc/default/init is read only.

$ sudo svccfg -s svc:/system/environment:init setprop \
     environment/LANG = astring: en_GB.UTF-8

$ sudo svcadm refresh svc:/system/environment

Now the system defaults to en_GB.UTF-8 for new processes, but remeber not children processes. So thing like cron and ssh have to be restarted, but I would go for a reboot.
$ sudo svcadm restart ssh
$ sudo svcadm restart cron


Settings for Non-UTF-8 locales (en_GB.ISO8859-15 / en_GB.ISO8859-1)

Non-UTF-8 locales such as en_GB.ISO8859-15 require the "system/locale/extra" package to be installed.
$ sudo pkg install system/locale/extra


$ sudo svccfg -s svc:/system/environment:init setprop \
     environment/LANG = astring: en_GB.ISO8859-15

Additional Options


These are set correctly on install, but added here for completeness.
$ svccfg -s keymap:default setprop keymap/layout = UK-English
$ svcadm refresh keymap
$ svcadm restart keymap

$ svccfg -s timezone:default setprop timezone/localtime= astring: GB
$ svcadm refresh timezone:default

My Raspberry Pi

How can you be a geek without a Raspberry Pi ? You can't!

Raided my daughter Lego box and now my Raspberry Pi has got a case.

Debian installed and updated. Planning to put my mail project on it.

  • Python
  • Django
  • Rabbit MQ
  • Twisted 12
  • lighttpd

Next project I'm planning to integrate Nagios with physical alarms/lights.
