Re: [gentoo-user] Can't boot from livecd
Hi had the smae problem on a dell with this chipset. Its not so much the chipset, but that the dell has a gap in the numbering of devices attached to it that the livecd cant deal with. The cure was to boot from a redhat 7 livecd and install from that. Worked fine. Also, dell has a legacy mode for the chip selectable in the bios - install has to be done in legacy mode, which can then be disabled when the new system is up and running on its own kernel. google will help a lot with this one BillK Chuanwen Wu wrote: The chipset is ICH8.

RE: [gentoo-user] Break In attempts
If you have iptables available in your kernel, a quick manual step could be to block all traffic incoming from that IP address. A statement like the following could work: iptables -I INPUT -s XXX.XXX.XXX.XXX -j DROP (This drops all traffic coming from IP address XXX... effectively, it simply looses the network packets and doesn't respond to it any more.) Of course this is a one time only, manual thing. There may also be processes/applications that automatically block unwanted IP traffic. Maybe somebody else may suggest such a solution (I'm not that familiar with this).

Re: [gentoo-user] LVM : pros cons
Never had a problem with LVM. On a mythTV box with LVM, started with 80GB IDE, then added in a 300Gb IDE, then a few months later another 300mb, sata this time. Basicly transparent to Myth I have avoided LVM on laptops before now because its extra complexity and I'll never add multiple disks. But, on a sony laptop without LVM - I have discovered that when I partitioned it in a rush ~18 months ago, I made the diagnostic partition 5 GBytes instead of 5 mbytes - and now I need the space. My options are to format it and symlink it into the tree, wipe and start again or image, repartition and restore. All have big disadvantages because this is my primary, work, not owned by me laptop (!). It would have been so much easier if I had used LVM ...

This is a _real_ nuisance. Besides that I doubt there is any

I have already disabled PAM authentication on sshd so that only users with a

Host-based authentication is one possible solution. Fail2ban

A bit more difficult is the ban by iptables. This one is

Of course you need a kernel with recent module and reject

Even worse, Windows sees the partition as unformatted rather than unknown and therefore might have no problem formatting it without warning. - Can't be used for /boot, usage for / needs initrd (my advice: keep /boot, /bin, /sbin and /etc on a normal partition). - It's one more thing that can break. - You can't use *parted to resize the underlying partitions. - I had trouble mounting my lvm /home partition (mirrored) with Ubuntu, possibly a missing kernel module in the default kernel or missing use flag. I didn't try to fix it, though. - You loose bit performance, but not much, you won't feel it without benchmarks. [1] Some simple advices: Create small logical volumes. It's easier to expand them than to shrink them (expanding reiserfs takes less than 5 minutes). If you are not shure wether you might need more space on ordinary dos partitions later on, don't create one big partition for lvm but several smaller.

Re: [gentoo-user] LVM : pros cons
On Sunday 07 October 2007, Philip Webb wrote: Does anyone have advice based on experience using LVM ? The majority of folks around here will have used LVM :-) I sb partitioning a new 320 GB hard drive soon for a simple desktop box. That is 8 times the size of the HDD in my present machine, which I haven't exhausted by any means. LVM seems more professional allows flexibility for unforeseen storage needs, this is it's main benefit on desktop class machines - the ability to resize volumes when you realize that you guessed wrong. There are others too :-) but it adds a layer of complexity potential problems arising therefrom. A total non-issue in my experience. I've never had an LVM problem yet, but maybe I'm just lucky. The one thing you do need to be aware of it that you require LVM support at boot time or shortly thereafter. So either compile it into the kernel, or make sure it's in the initrd. For a gentoo system using roll-your-own kernels, the consensus seems to be a regular / volume of 500M-1G is plenty and everything else is on LVM. That way you avoid the issues of not having the required support to be able to mount /. We don't build distro kernels that must boot on everything out there, we have the luxury of customizing everything I wonder whether LVM slows down disk access No. See my other mail. whether there's a disaster lurking unseen if anything goes wrong with LVM: a bad package update, a damaged config file or file storing LVM's layout would seem to risk losing everything on the HDD require re-installation. Not true. You *already* have many layers of software between user space and disk, any one of which can go wrong at any time. LVM metadata is stored in text files and it maintains many historical copies of previous configs and it's easy to fix if it ever goes wrong. I've never seen a *real* LVM error, but I have matched myself do some really dumb things and I could fix them every time. Seriously, the problem LVM solves has been known about for decades and the method used was worked out about the same time. It's a mature technology that is *very* well understood, completely the opposite of drivers to support some latest new-fangled chipset. I would be much more worried about that code trashing your disk than LVM. Just to put it all into perspective... Extra benefits of LVM: You won't need this right now for your simple desktop with one drive, but it's good to know what else LVM can do: Snapshots. You can freeze the state of a filesystem at any time and LVM will track the changes since then until you release the snapshot. This is a lifesaver if your job is to perform backups of 4TB databases that can never be taken down for backups. Huge volumes: LVM is the only way on Linux to be able to get local volumes bigger than any single disk. Again, on servers, 2TB+ databases are becoming commonplace. If you need any more convincing, IBM mainframes and HP machines running HP-UX have required you to use LVM for years now - you can't get to the disks without using LVM. If it was risky, do you think those hardware vendors would have gone down that route? alan -- Optimists say the glass is half full, Pessimists say the glass is half empty, Developers say wtf is the glass twice as big as it needs to be?

If you build an application that has optinal (on compile time) support for this, but downgrade the headers after that to say... 2.6.10 you might see funny stuff happening.

Moving the heads just once more because of file fragmentation probably takes longer than the entire LVM lookup A year or two ago it was possible to measure a performance hit - for instance we had some Supermicro PCI-X based machines with 3Ware RAID cards where we could get (quoting from memory here as it was a while ago) uncached sequential scan rates of about 1Gb/s without LVM and somewhere in the region of 800Mb/s with it. However that was then, and this is now - LVM and hardware have no doubt improved , so it would be interesting to do the test again (if we do I'll let you know). I would think that for the OP's use case (i.e 1 disk on a desktop box) there will be no measurable difference at all. Cheers Mark -- [EMAIL PROTECTED] mailing list

I got lucky; a rescue disk allowed me to create a bogus symlink to the old library so that boot could proceed, at which point I remerged the broken command and no longer needed the bogus symlink. I have since written a perl program which looks for such broken libs. I have no idea why gentoo's revdep-rebuild didn't find it.
