I apologize for inadvertently password protecting last night's article about Nagios, Parent Hosts and traceroute on the Internet. Somehow, my Iceweasel has the firm opinion to enter my Blog's admin password in all form fields labeled "password" on blog.zugschlus.de, and the article entry form happens to have one like that. And last night, I forgot to delete it. Sorry.
Thanks to mika for making me aware of that.
