Netfilter module name oddity
Maybe I slept through some old thread about this, but nothing came out of searching Google about this: why do I have so many similarly named modules in my kernel? who is the clown who decided to break some very basic naming conventions of module filenames and give me a small heart attack? 10809 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_connmark.ko 12079 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_CONNMARK.ko 10066 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_dscp.ko 11193 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_DSCP.ko 9885/lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_mark.ko 10903 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_MARK.ko 10137 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_rateest.ko 13381 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_RATEEST.ko 9193/lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_tcpmss.ko 12506 /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_TCPMSS.ko 9141/lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ecn.ko 9975/lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ECN.ko 8762/lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_ttl.ko 9232/lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_TTL.ko At first glance I was sure it's some sort of a weird rootkit attempt, but apparently it's all kosher and I'm the last silly person on the planet to notice. Now I just need to know why this makes sense to whoever is maintaining this code (Rusty?) and how come I have not found any info about this with any combination of relevant search terms... -- Tool of the trade Ira Abramov http://ira.abramov.org/email/ ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

As for Googling, my first attempt to search for netfilter module naming convention yielded http://jengelh.medozas.de/documents/Netfilter_Modules.pdf at #2 from the top, and the very beginning of this document supports my guess.

Linux Friendly Netbook?
Hi all, I am writing to both lists because I think the problem of bouncing mails on the Linux-IL list still persists - at least for me... I want to buy a Linux friendly netbbok, preferably Ubuntu 8.04 friendly. My requirements: Wi-Fi, Bluetooth, comfortable keyboard. I'll use it mainly for on the go Media Player and some basic browsing. I want the Bluetooth support to be able to connect my stereo Bluetooth headset and transfer files via OBEX to my Nokia E71 smart phone. Thanks! .::.

I want the Bluetooth support to be able to connect my stereo Bluetooth headset and transfer files via OBEX to my Nokia E71 smart phone. I have an MSI Wind U100. They cost around 2300 NIS with the 6 cell battery (don't get the 3), 2g RAM and a 160G hard drive. Wifi, bluetooth, etc are included. It has 3 USB ports, but note that it does NOT have an RS232 or Parallel port, so if you need to interface that something that needs it, you are out of luck. Many of those devices don't work with USB convertors, but they are now rare enough that most people won't even know what I am talking about. I run BSD on mine, but it does sort of run Ubuntu. I had an 8.10.2 memory key set up for it and it did everything except Wifi. (I did not test the camera). The Wifi driver was released a few weeks before 8.10 was, so it was not included. A hard disk installation would not have that problem, you can add the wifi drivers in a minute with an ethernet connection. When 9.0.4 came out, I downloaded and booted from the live disk. It worked fine with Wifi, but the build a bootable USB memory key program works, but the memory key is unusable due to a kernel bug. I also installed it on a desktop and after the first update, my ethernet stopped working (the file that defined the interface suddenly no longer had it in it). I tired to run 8.0.4 LTS on a server and found that so many things never worked that I needed, I was unable to use it. It now happily runs 8.10, but there were bugs that had strange work arounds that I had to research to get them to work. IMHO if you are using Ubuntu as a replacement for Windows it's a good choice, but if you do anything out of the ordinary, you can see it suffers from the same disease Red Hat Linux suffered from 10 years ago. (get it out the door, worry about the bugs later) Geoff. -- geoffrey mendelson N3OWJ/4X1GM Jerusalem Israel geoffreymendel...@gmail.com ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: Linux Friendly Netbook?
I am running Ubuntu 8.04 on Lenovo 3000 N100. Everything I need work. I did not test the fingerprint detector and modem. Wifi works out of the box. -- Ori Idan On Sun, May 3, 2009 at 7:47 AM, Amichai Rotman amic...@iglu.org.il wrote: Hi all, I am writing to both lists because I think the problem of bouncing mails on the Linux-IL list still persists - at least for me...
