Almost weekly DS-Line quality report


No resyncs so far but a considerable number of "Forward Error Corrections". Regarding the speed I got no faster downloads than 1,3 Mbit/s, but I hadn't it tested yet.

UPDATE: Sooo, with a cable connection to my router (rather than wireless) I hit 1,75 Mbit/s.

the rtorrent-on-debian-NSLU2-crash-issue

I'm still having problems with rtorrent on my NSLU2. It keeps crashing after two hours or so no matter what I do ([1], [2]) with .rtorrenct.rc.

However, yesterday it came across my mind, the actual problem (which is resources) could be connected to the user with whom I start rtorrent. rtorrent does not run as root but as a user with limited privileges on my NSLU2. My thinking was that Linux allocates more resources to root than to inferior users.

So I tried running rtorrent with screen and root. But still, not really a change.

I'm still wondering about the positive reports on rtorrent with the NSLU2 that e.g. google brings forward. When I asked once a forum user about how was running rtorrent, he basically replied:

"Well, it never crashed, but I've never downloaded anything with it".

So, do the positive reports only come from users who do not actually use their rtorrent?

Anyways, I'm running out of ideas on how to get rtorrent running stably. The ultima ratio seems to be to start with a fresh installation of debian...
argh.

Fritzbox 7170 connected directly to the "TAE" / No Splitter!

Yes, it is somewhat complicated. You'll need a proper cable to do that. And it seems you have to build it yourself. I'm still gathering information on that.

Nah, it has changed a bit. Watch the spectrum.



The spectrum is more square-edged or steppy between 64 and 90 kHz while the signal/noise quality is rounder. Also, I gained one dB in Signal/Noise-ratio... Yay!

Sole downer: lost 4 Kbit/s of potential upstream.. :)

Beta for Fritz!Box 7170: Firmware-Version 29.04.55-10393

DSL Version and figures almost the same, so I won't post any screenshot for now. Since I do not use the conventional (fixed) line any more (only VOIP), my next try is connecting the Fritz!Box directly to the TAE Box; I do not want to use the splitter any more. Effects on Signal Quality will be posted here soon.
