| Post subject: | ssh on knoppmyth, extremely high cpu usage...? |
There is something seriously....strange about ssh on knop myth. I have ssh'ed in using putty. the console is lagged (I'm on lan) on an athlon 2100+, 1GB ram, a7n266-vm. If I watch TOP on the monitor (not using tv-out on my mythbox), and I start typing in the putty window from windows, cpu usage shoots to from 35-60% on sshd. Any idea what might be going on ? |

Sounds like the same symptoms I've been having. I posted some more info about it in http://mysettopbox.tv/phpBB2/viewtopic.php?t=1095 I still don't know the solution yet but hopefully someone will be see the problem and help us out. Do you have onboard lan? What type of motherboard do you have? |

my motherboard is a7n266-vm (see post). I think the nvnet drivers just (probably) suck. Rob |

Well both of our boards are made by asus so maybe therein lies the problem. How would we go about getting new drivers. Can we apt-get a new driver or do we need to download the source and compile it? |

well basically the nvnet drivers do suck, and there is an open source driver that works better, but it is not in the stock kernel untill the most recent ones not the one in knoppmyth. You could probably get the source and compile it without a kernel recompile, but I'm not positive. And I can't seem to remember the name of the module at the moment, but google could probably find it for you rather quickly. |

Would something like this work? http://www.scyld.com/network/ethercard.html I'll admit I'm a newbie when it comes to compiling drivers and such. |

well actually here is the driver I was talking about. It says beta quality, but it has been included in the 2.6.3 stable kernel, and I have heard people say it works much better than the nvidia driver and specifically that it reduces the cpu load. unfortunately that looks like a kernel patch, so it would require a kernel recompile. |

There are about a zillion files here. Anyone know which one we need? Rob |

My guess is this one:http://www.hailfinger.org/carldani/linux/patches/forcedeth/forcedeth_2_4_patch_v23.txt Of course it would be nice if those that have compiled 2.6 would post instructions on how they did it as 2.6.3 on up include this... |

Ok, once I download that file, where do I put it, and what do I do with it ? Rob |

well my suggestion would be if you are not linux savy just live with the high cpu usage, and wait till we get a kernel with this driver included. Otherwise you will need to do some research on patching and compiling the kernel. Hint: It's not a simple process for the uninitiated. |

Well, It's gotten so bad that if I rip a dvd and then copy some files with scp at the same timem, it sometimes says something to the effect of "the backend isn't responding...this is really bad" ... I can patch & configure and do custom kernels for OpenBSD all the time. How different/more difficult is this? Rob P.S. I also have compiled my own drivers for the hollywood+ and have the modules loaded, but haven't figured out all the right mplayer switches yet

well if you are familiar with patching and kernel compiles it isn't that bad. the difference between the other drivers you mentioned and these is that you actually have to apply the patch to the kernel and recompile the kernel. You can't just compile the drivers against the kernel. The biggest problem with this is that you will have to also recompile lirc, and ivtv(if your card uses it) and possibly other modules for the new kernel. |

Ah I see... Thanks. I was under the impression I could compile the drivers for this particular kernel and load the module and be done. That doesn't seem to be the case. I guess I'm going to go and grab another nic, disable the onboard nic, and then try to get the rest of what i need working: 1) Optical out 2) X/mythfrontend running at 1920x1080p 3) tuner cards working Rob |
