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

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()

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

# portmaster textproc/php5-xml

# service apache22 restart

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

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

or

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

That’s it.

CentOS: lsb_release: command not found

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
