Conntrack table flood

Recently we had problems with our gateway, connections were dropped and so on.
After a bit of investigation we found that it was due to a bugged game using Javascript which, when it ran on Firefox, opened connections in a loop flooding the connection tracking table in a matter of hours. Once found, it was easy to fix. This was also the occasion to tighten the timeouts values of nf_conntrack a little bit. Indeed 5 days timeouts for established connection doesn’t really make sense when your public IPv4 change every 36hours or so.

GTranslate and Weboob

This is a quick interface to translation tools. In particular it was made to interface a specific tool from Weboob. For those who don’t know Weboob is a collection of applications able to interact with websites without a browser and mostly from command line interfaces. This allows GTranslate to use web translation services such as Google-Translate. However it can also be used with others translation tools as long as they offer a simple command-line way to translate a text from one language to another. It can also be easily adapted to any tool to provide an interactive conversion from one type to another. I made this tool to try out GTK-3 and GtkBuilder and actually building interfaces with Glade is really easier.

Speaking about Weboob I think this is a very good initiative because I’m getting a bit sick of these overpowered web-browsers outshining the application landscape. I mean we should tend toward a web of services but instead we just spend our time recoding everything we already had in JavaScript and shiny HTML5 interfaces. And I think, or rather hope that the future of web lies outside the browsers.
