vmware: CD/DVD ROM drive is stuck in connecting mode

kenno — Mon, 11 Feb 2013 03:39:04 +0000

As the title says, if the CD/DVD device of your VM is stuck in connecting mode, one thing to try is to shutdown the vSphere client, and restarted it.

I found this solution from http://communities.vmware.com/message/1784438, and it worked for me.

PHP Fatal error: Call to undefined function utf8_decode()

kenno — Tue, 25 Dec 2012 03:57:20 +0000

This occurs on a FreeBSD server. According to this post[1], I need to install php5-xmlphp5-xml.

# whereis php5-xmlphp5-xml php5-xml: /usr/ports/textproc/php5-xml # portmaster textproc/php5-xml ... # service apache22 restart

FreeBSD: Fatal error: Call to undefined function session_name()

kenno — Tue, 25 Dec 2012 00:08:49 +0000

I just setup Apache and PHP on FreeBSD 9, configured a vhost, then when I tried to access it, I got the following error:

Fatal error: Call to undefined function session_name() in /srv/www/sugaku.domain.com/inc/init.php on line 144

so apparently, the “session” support is missiong from php5 installation. To fix it, I need to install php5-session port.

Let’s do it.

# whereis php5-session php5-session: /usr/ports/www/php5-session portmaster www/php5-session

If the installation is successful, then we can restart apache.

# service apache22 restart

# /usr/local/etc/rc.d/apache22 restart

That’s it.

CentOS: lsb_release: command not found

kenno — Sun, 21 Oct 2012 22:53:07 +0000

First let me declare that I’m new to CentOS. The folowing is a note to self which demonstrates how we search for a package that provides some commands and intall it using yum on CentOS.

When I ran ‘lsb_release -a’, the following message is returned:

-bash: lbs_release: command not found

To fix it, we need to install the package which provides lsb_release command.

# yum provides */lsb_release ... redhat-lsb-4.0-3.el6.centos.i686 : LSB base libraries support for CentOS Repo : base Matched from: Filename : /usr/bin/lsb_release


redhat-lsb-4.0-3.el6.centos.x86_64 : LSB base libraries support for CentOS

Repo        : base

Matched from:

Filename    : /usr/bin/lsb_release

dkms-2.2.0.3-2.el6.noarch : Dynamic Kernel Module Support Framework Repo : epel Matched from: Filename : /usr/lib/dkms/lsb_release

So, let’s install redhat-lsb package:

# yum install redhat-lsb

Fix missing icons and ugly theme in Evolution on Kubuntu 11.10

kenno — Tue, 18 Sep 2012 06:43:05 +0000

This how Evolution looks like on Kubuntu 11.10 (Oneiric).

To fix this, make sure this package is installed: “humanity-icon-theme”, then create $HOME/.config/gtk-3.0/settings.ini

[Settings] gtk-fallback-icon-theme = Humanity

Restart Evolution, and it should be fixed.

Fix: Xfce 4.10 panel no longer expands

kenno — Fri, 24 Aug 2012 01:35:35 +0000

After upgrading to Xfce 4.10 from 4.8, I noticed that the clock/notification area no longer pushed to the right edge of the panel.

This is due to a change in the Window Buttons panel plugin which no longer expands to fill the available space[1].

To emulate the old behavior, add a transparent separator between the window buttons and the clock/notification area, setting its expand property.

Voilla!

FreeNX: Disable Persistent Session

It’s a bit unintuitive to set non-persistent session on FreeNX server. After a few attempts, here is the working settings:

Edit /usr/NX/etc/node.cfg:

ENABLE_PERSISTENT_SESSION="" DISABLE_PERSISTENT_SESSION="all"
