In fact ... http://bsd.dischaos.com/2008/07/11/openbsd-interface-groups-manual-carp-failover/ Flash clients don't comply with the XMPP protocol. This is due to some limitation/security features in the flash itself. The problems are: flash sends null terminated stanzas and expects the same from the server opening stream header is a bit different than expected. In case of a flash client it's: <flash:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' ... http://bsd.dischaos.com/2008/07/07/jabber-servers-with-support-for-flash-based-clients/ Although FreeBSD runs under VMware  and there's even an option for it in the GUI management tool, it doesn't run perfectly. timekeeping The first problem with FreeBSD under VMware is time synchronisation. After running FreeBSD for a few minutes you'll notice that its timer is completely out of sync comparing with the ... http://bsd.dischaos.com/2008/07/02/running-freebsd-under-vmware/ Imagine you have a FTP server behind your NAT/firewall server and you want to (or rather have to, because why would you really _want_ to do it?) give access to this FTP from outside world. As FTP is a really crazy old protocol it's not as easy as with HTTP or ... http://bsd.dischaos.com/2008/07/01/reverse-ftp-proxy-with-pf-and-openbsd/ I couldn't find on symfony's website what options you can pass to the object_select_tag function. It's definition looks like this: function object_select_tag($object, $method, $options = array(), $default_value = null) and options can be: peer_method - peer method you want to use to fetch options. useful for sorting, limiting output etc. text_method - method used ... http://bsd.dischaos.com/2008/06/27/symfony-object_select_tag-options/ I'm not sure if it's the best way of doing it, but this method of creating web services with wso2 works for me. A bonus here is that it doesn't involve creating or modyfying any XML/WSDL files as all this is autogenerated or handled by the framework itself. This example service ... http://bsd.dischaos.com/2008/06/04/creating-web-services-with-wso2-wsfphp/ Update (2008-06-04): This patch also works with the latest (1.3.1) version of wsf/php. WSO is a web services framework I've been recently playing with. There are versions of it for C, php, ruby, perl, and some other languages...

When I was installed the server around 7 years ago, qmail was a very trendy alternative to the "bad and insecure" sendmail, FreeBSD's default MTA. Now, after a few years have passed, qmail is no longer so trendy and chicks don't dig ... http://bsd.dischaos.com/2008/05/07/ezmlm-idx-postfix-quick-and-dirty-howto/ OpenBSD 4.3 has just been released. I've just tested installing it on a net 5501. The installation procedure is exactly the same as  for OpenBSD 4.2 described here. The only exception is that I couldn't find pxeboot on the install43.iso file downloaded from ftp.openbsd.org (I'll check if it's on the ... http://bsd.dischaos.com/2008/05/01/openbsd-43-on-the-soekris-net-5501/ Why OpenBSD? A bit of explanation first. I did some test installations of FreeBSD 6.x on an older Soekris net 4801 box and found out, to my surprise, that it wasn't running as fast and stable as OpenBSD. Additionally, comparing to OpenBSD, installing FreeBSD over PXE on Soekris was a bit ... http://bsd.dischaos.com/2008/04/28/running-openbsd-42-on-the-soekris-net-5501/
