Configuring Syslog-ng on Ubuntu

Syslog-ng is a replacement for the default syslog daemons you get with most Linux distributions. The advantage of syslog-ng is that the configuration is easier to understand, and it gives the sys-admin numerous advantages. Especially in complex environments.

Let's say we have a RADIUS environment which is able to send authentication and accounting information through syslog to external devices. And let's assume that a relevant part of this syslog information is needed by a department within a large cooperation.

Installing syslog-ng (on Ubuntu) is done by the following command:

# sudo apt-get install syslog-ng

Through the use of syslog-ng we can store, and/or forward syslog information based on the following (but not limited to):

• source IP address
• destination IP address
• syslog level
• content in the original syslog message by using regular expressions.

All this can be configured in the /etc/syslog-ng/syslog-ng.conf file.

Moving from Flickr to SmugMug

Over the last couple of years, I've been storing my photos online @ Flickr. But I fear that time has come to move forward. Forward to another service for the next couple of years. The main reason for moving is that Flickr doesn't seem to innovate. No innovation basically means going backwards, in these days.

Flickr is a WYSIWYG environment. What you see is what you get, and not in the way this term is usually used on the Interwebs. There's no way of changing the coloring or appearance (white only). No way of integrating into another website (e.g. changing the URL).

Unable to Upgrade Firefox on OS X

Today I tried to upgrade Firefox 5.0.1 on my iMac to version Firefox 6, but it failed with some 'weird' error;

The operation can't be completed because the item libsmime3.dylib" is in use.

Weird because I didn't have FireFox running at the time. Removing Firefox didn't work either, since I couldn't remove it from the Trash (same error).

Turned out that I had the Cisco AnyConnect VPN installed on my system (process name: vpnagentd). To 'unload' this process enter the following in Terminal:

sudo launchctl unload /Library/LaunchDaemons/com.cisco.anyconnect.vpnagentd.plist

Install Firefox, and enable the vpnagent again by entering the following in Terminal:

sudo launchctl load /Library/LaunchDaemons/com.cisco.anyconnect.vpnagentd.plist

And all should be well.
