Anthony Bryan seems to have worked hard lately and we've seen him submitting his Internet Draft for Metalink XML Download Description Format on the http-wg mailing list, and now the 02 (zero two) version is up for public browsing and commenting at
Since I'm doing my share of both FTP and HTTP hacking in the curl project, I quite often see and sometimes get the questions about what the actual differences are between FTP and HTTP, which is the "best" and isn't it so that ... is the faster one?
FTP vs HTTP is my attempt at a write-up covering most differences to users of the protocols without going into too technical details. If you find flaws or have additional info you think should be included, please let me know!
The document includes comparisons between the protocols in these areas:
Active and Passive
Encrypted Control Connections
Name based virtual hosting
With your help it could become a good resource to point curious minds to in the future...
Next week in Sweden (June 18th), as reported in several places lately including slashdot, the Swedish parliament is supposed to vote for the pretty far-going law allowing FRA (a swedish defence organization previously involved in radio-surveillance etc) to wire-tap phone calls and computer traffic that cross the Swedish borders. The majority in the parliament is for the law, while it seems most of the ordinary people are against it. The hope is now that a few people will vote against their parties, that they will have the guts to stand up and "do the right thing" instead of following the party line.
I won't go into how silly, stupid and bad such a law is but I'll instead just show this great video to all swedes:
This banner says (roughly translated by me) "On June 18th the government will take away your personal integrety. All internet traffic, all phone calls, all email and SMS traffic will be wire-tapped starting January 1st 2009. Big brother sees you! ... and violates the Swedish Constitution."
I noticed the new site publicsuffix.org that has been setup by the mozilla organization in an attempt to list public suffixes for all TLDs in the world, to basically know how to prevent sites from setting cookies that would span over just about all sites under that "public suffix".
There's no word on the site if IE or Opera etc are going to join this effort.
I tried to find some official and recent figures or statements from some of the more IPv6-positive people and companies, but I failed to find much updates from after the year 2000 or so...
Speaking of network things that aren't so successfully deployed: DNSSEC. Apparently iis.se (runs the Swedish TLD) tested 10 broadband routers (article and PDF in Swedish only) how well they support this (I believe mainly because .se tries to be a pioneer in DNSSEC), and 7 of the tested ones failed... Personally I've never liked the fact that DNSSEC isn't really crafted to do it securely all the way.
Bryan is a friend who recently found out that his company is switching proxy to a different one and apparently both corkscrew and proxytunnel have problems with this new piece, and since libcurl offers quite a lot of functionality to accomplish almost this, a new project was born: curltunnel.
One immediate benefit of using libcurl is the support for multiple authentication methods, in fact more than any of the above mentioned tools.
However, it seems our first quick stab at making this tool (currently 278 lines of code), made it work for several common cases but... not for Bryan's new proxy.
The current theory is that the proxy actually checks for SSL traffic and only lets that through, and thus it prevents the ssh server banner to appear when we try to tunnel through the proxy to a remote ssh server on port 443. If further testing proves this correct, we will of course have to add a SSL layer to the mix.
My wife wants to keep some videos found on youtube, and I really can't recommend just keeping bookmarks to a random web site like that. Not if you want the content to be available in a few years ahead, or even ten or twenty years. Then downloading the files to keep the locally is the only sane way to make it somewhat more reliable.
To download the files you can do it with a browser or with a command line tool:
During the summer 2001, me and my wife toured Vietnam and we had a great time. For that occasion I set up a little online diary that would allow us to post entries while on the road, to allow our families and friends back home to be able to keep up with what we were doing.
Fast forward to present day: the diary "submit new entry" form is still left on my site, and while it no longer works (it hasn't worked for many years) - it is still one of the most visited pages on my site! It seems the automated spam bots find it and submit crap to it... the crap doesn't end up anywhere to be seen nor is it even stored on the server, but it clearly identifies evil machines! Isn't that a honeypot as good as any?!
So far during September 2007, no less than 309 unique IP addresses have issued a POST on that page..
