Lioux launched a BitTorrent campaign.
He persuaded me to install the bittorrent port on jim, and donate 6KB/s (ca. 40% of my upstream bandwith) to his project. Additional i have set a limit of 6 connections, calculating that each connection should get 1KB.
After running one night, on next morning my nagios was crying because “the Internet is slow”. I checked with Hendriks excellent slurm program and noticed that my upstream was blowing out full speed (16KB/s, yes my ADSL line is slow).
I checked with tcpdump what caused this traffic and immediately noticed several wellknown hosts as primary offenders:
10:49:17.908038 IP 21322530218.direct.eti.at.53481 > g164193.upc-g.chello.nl.acmsoda: F 1347279866:1347279866(0) ack 1734755715 win 33304
10:50:05.497482 IP 21322530218.direct.eti.at.52573 > panda.droso.net.6881: P 1:49(48) ack 1 win 33304
10:50:05.545402 IP 200-140-3-148.bsace703.dsl.brasiltelecom.net.br.54871 > 21322530218.direct.eti.at.7241: R 3804027892:3804027892(0) win 0
10:50:05.606741 IP 21322530218.direct.eti.at.7241 > creme-brulee.marcuscom.com.51748: FP 0:7(7) ack 1 win 33304
0:50:05.607486 IP 21322530218.direct.eti.at.54575 > foo.lovett.com.7241: . ack 1 win 33304
. Obviously lioux persuaded some other fellow commiters (kwm, marcus, erwin and ade) to run BT as well and now we exchange our distfiles via BT (hooray!).
It looks like the traffic shaping algorithm is far from optimal and according to netstat the maximum connection number was also violated. And why is so much traffic required to coordinate the peers, as we all have the relevant files and don’t download anything?
My conclusion, currently bittorrent can’t compete with fetch(1), ftp(1) and an established mirror hierachy when it comes to distributing free software.
Since today is the last weekend before university starts again, i took the time to upgrade to the latest MovableType version.
My Killer Feature is the Trackback moderation and the SpamLookup Plugin. Let’s see if how they work.
I will upgrade the FreeBSD port this time, since MT2.x isn’t available anymore.
One of the reasons my personal calendar is still on dead wood is, that if it was electronic, I need to access it from several machines, my Desktop@home, my Desktop@work, my Laptop.
Since my Laptop is a Mac and one of my Desktops too, i tried to use ical. Setting up WebDAV was not as complicated as i imagined, and configuring ical to publish a calendar was easy too.
Editing with Mozilla Sunbird and Korganizer worked without a problem.
But i was not able to tell ical that the subscribed calendar is editable. *grr*
Today i wanted to upload some more pictures to thegallery, but gallery-remote failed with a mysterious error. Updating to gallery2 was not an option, as it requires MySQL.
So i continued my crusade against ugly php apps and switched to swiggle.
I have made a small modification to swiggle, the description can now be displayed on the index page. Grab the patch from here.
I am finally back in Vienna after struggling with Deutsche Bahn. The only way to get back to Vienna was by paying extra for travelling in a stone old “Schlafwagen”, all other seats were already booked out.
In Vienna i had to turn on the heating because it is so cold….
I am now catching up with Email, uploading pictures etc.
I uploaded a few pictures to the just installed Gallery.
I will upload a few more pictures next week.
Unfortunately there is no Internet access at our holidayhouse like advertised. Only on weekends a friendly neighbor plugs in his open WLAN Accesspoint.
A few days ago a technician put this socket into the wall, but i have no idea how to use this for internet access.
Chris guessed that it is a danish telephone socket, so a DSL Modem is still missing.
While migrating my mailserver i consilidated my .procmailrc, but unfortunately it is still too large:
knut% grep List-Id .procmailrc | wc -l
I have been working there for more than four years, nearly half of my working life.
Now I just passed the keys to my office to my successor, Christoph Schwarz. He is also a FreeBSD user, so my workstation tl.kom.tuwien.ac.at (my first FreeBSD Desktop computer) will hopefully continue running FreeBSD :-).
Since I now have 20 hours/week more free time i will hopefully speed up studying at university and i will probably increase my FreeBSD commit rate (For the first time since 2 years i dropped out of the Top 20 most active ports commiters per anno).
