sniffing some fresh tomatoes

Perhaps the title is a little misleading, but it’s an opportunity to combine two of my greatest loves: food and computers. I suppose even this intro is misleading. Oh. Forget it. Lets get down to business. And this time our business is rather short (and sweet).

Running tcpdump on my Linksys router (well, Buffalo WHR-54GS to be precise, but the same famous WRT54G clone that runs open source firmware).

cron woes – file timsetamp monitoring plugin for munin

I don’t like being late. It runs in the family. My dad is so obsessed with being late that he’s always early. How embarrassing. Unfortunately I seemed to have inherited it from him. I do however try to compensate. I am deliberately late on-time. I usually plan to be a bit late.

Anyway, enough about me.

JDK 5 Debian etch Virtuozzo installation oddities

Not a particularly interesting post, unless you happen to be running Debian 4.0 etch running on Virtuozzo host and are trying to install JDK5. I saw a post with a user reporting the same error on the parallels forum , but couldn’t find a clear solution, until I bumped onto a weird forum in German, which luckily linked to a related bug report (in English).

Turbogears, Lighttpd and WSGI for real dummies

Just so to set the records straight, I’m the real dummy here, as you would obviously see.

I absolutely have no experience with python, lighttpd, turbogears or wsgi, fcgi but I was given a task to set it up on a server. All I used was some online posts and common sense. Normally I wouldn’t have to post a blog entry about it, most of the stuff is already out there. On this occasion however, I felt there’s some missing documentation, or else – simply because I don’t know anything about any of these it was more tricky than it usually is. Perhaps it’s one indicator how this all seems from the sysadmin perspective, as opposed to a turbogears developer.

Windows 2003 split DNS

[Migrated from tuzig.com]

This is something I thought would be simple. Then I began scratching my head reading all the posts on the web, thinking I might actually need to get a proper book. Finally I realised it was actually quite simple…

iCal on Mac with Apache on Windows

[Migrated from tuzig.com]

I’ve been struggling with getting the iCal app on Mac OS X to use a shared calendar on Apache installed on Windows and using domain authentication (SSPI). It is all supposed to be so simple, yet it didn’t work. Authentication failed with this message:


Access is denied at http://server.com/file.ics with this login and password

When using Safari and accessing the same webDAV url authentication works just fine. I could even download the calendar file from Safari and it would open it in iCal, but for some bizarre reason – neither Subscribing nor publishing worked

I’ll leave out all my trials and errors. Eventually it came down to SSPI authentication not working well with iCal, even with SSPIOfferBasic On and SSPIBasicPreferred On. Only when I added SSPIOfferSSPI Off did it start working…

I’m still slightly confused why no modification is allowed to subscribed calendars in iCal, as it does let you do it in Sunbird, but at least you can publish your own calendar and subscribe to other’s

Rsnapshot Server on Windows

[Migrated from tuzig.com]

2009 Aug 14 Update: Looks like rsnapshot is now packaged in cygwin! Thanks to pseudo-anonymous coward for the comment! Some of the information below may still be of interest, so it’s left unchanged.

Rsnapshot is a great tool for backing up data, keeping versions and using relatively minimal disk space. From the rsnapshot website:

“rsnapshot is a filesystem snapshot utility for making backups of local and remote systems.
