Re: [gentoo-user] Re: Rooted/compromised Gentoo, seeking advice
Another idea to help with your forensics would be to bring a netstat and lsof binary over to your machine and run them to see which actors are running and trying to get out. That could help you detect what is running on that machine and google your way from there. If your kernel has been subverted then userland is irrelevant, a kit can simply hook the system calls those binaries use and return whatever it wants you to know. -- Kyle

AddHandler cgi-script cgi py Thanks, Kyle, you've been getting me closer and closer. If I'm starting to get the new stuff, AddHandler declares certain extensions. Up until last month, extensions were not required, and in fact my CGI programs have never had them. It used to be enough to use ScriptAlias, and put an executable in the directory. If it was a script with a shebang, or a compiled ELF program all was well. If I were going to use extensions, it would be .py or possibly .python, not .cgi or .pl.

Re: [gentoo-user] openvz kernel and ext4
Ext4 was very new around 2.6.27,. The kenel is likely refusing to mount the filesystem because the kernel driver is experimental (old) and the filesystem was created when a different kernel was loaded (non experimental ext4). Using the old driver could compromise the integrity so the kernel refuses. You might have better luck with a more recent kernel.

Re: [gentoo-user] Minimal Gentoo with X
Since space is a issue for you, you really only need the kernel sources for the kernel you are using. One could argue that if you have a well built kernel and don't plan to change it in the future, you could remove its sources too. I would save a copy of the config tho. I'd certainly argue that. A single set of sources can take up more than half a gigabyte after compilation. If you use make install to install the kernel, it puts a backup of the config in /boot automatically. It is also good to keep the System.map and vmlinux file in case you or someone else needs to debug your kernel traces. -- Kyle

tar cf - $old_dir | ( cd $new_dir: tar xf - ) tar cf - $old_dir | ssh $other_host ( cd $new_dir: tar xf - ) ^ The ':' separating commands should be a ';'. Using the -C option would be a little easier, but your method also would work for star. This piping through ssh is quite cool, isn't it. whoops, good catch! If $old_dir is the root partition, I would bin-mount it first to somewhere else, so other directories mounted to it (especially/dev, /proc and /sys) are not copied: mount -o bind / /mnt old_dir=/mnt that too, copying over /proc/kcore is never fun ;P -- Kyle
Re: [gentoo-user] Advice/best practices for a new Gentoo installation
- be aware of cylinder boundaries when partitioning (thanks to the recent thread) +1 - utilizing device labels and/or volume labels instead of hoping /dev/sda stays /dev/sda always +1 - initrd - I've never used one, but maybe it's needed if root is on software RAID? It's not technically needed and boot times are faster without them. I'm a fan of statically compiled kernels too but that's more to prevent malicious LKMs. - grub/kernel parameter tips and tricks... i'm already using uvesafb, and don't dual-boot with MSWin or anything, just Gentoo - better partitioning scheme than my current root, boot, home (need portage on its own, maybe /var as well?) putting portage on it's on partition is a good idea imo, I usually use reiserfs because it handles large amounts of small files well. - some kind of small linux emergency/recovery partition? equivalent to a liveCD maybe. I usually keep a bootable usb in my bag for recovery, which also works if there is a problem with the disk/raid. - best filesystem for portage? something compressed or with small cluster size maybe. reiserfs - SSD vs 1rpm vs big-and-cheap hard drive for rootfs/system files. I lean toward the latter since RAM caches it anyway. SSDs can make things snappier for boot times. Having lots of ram for disk cache eliminates the benefit after booted since ram is even faster than a SSD. - omit/reduce number of reserved-for-root blocks on partitions where it's not necessary. I never get close to filling my disks so never have bothered with this - I have never used LVM and don't really know about it. Should I use it? will it make life easier someday? or more difficult? I'm not a fan, if you don't plan on changing your partition sizes I don't see a lot of utility in adding the extra layer of complexity. - Is RAID5 still a good balance for disk cost vs usable space vs data safety?

I've built many RAID6 arrays with all three controllers - 8x 1TB and 8x 1.5TB and I'll usually start a foreground init and let them run overnight because it does take a long time.

i compiled the uhci and ehci into the kernel. i need to double check
the usb_storage thing. maybe this is the thing i missed.
UHCI is for Intel and VIA ... OHCI for others (these are both USB 1.0{1}
EHCI is for all USB 2.0
Make sure you have the correct UHCI/OHCI ... you only need one of those.

If I got this wrong, just delete it. FXS is meant to interface to a telephone set, so it gives talk battery and (as needed) ringing current. FXO is meant to interface to a line from a telco switch, so it accepts battery (if the circuit it's hooked up to doesn't give talk battery, you have no circuit) and expects to be rung into, so it detects ringing battery. Most of the time, both FXO's and FXS's offer options to operate in loop start (regular POTS) or ground start mode. Write me if you need more on that last. Options like reverse battery aren't usually offered in FXO/FXS cards. You usually have to give a FXS card your own source of ringing battery, not FXO, because an FXO is expecting to have ringing battery sent to it (from the telco switch it's connected to) to begin with. This brought an idea in my mind... the phone lines in our houses here in Quebec,Canada are set so the line comes into the house at one point (called dmark i think) then it is spread around. if there is no service, then there is no dialtone, if one phone is used, then all phones can hear the conversation if picked up. normal stuff. but what if i were to setup a pc to work with asterisk and somehow plugged a FXS (i guess?) card to any phone jack in the house. then any normal phone would be networked to that FXS card and anything done on them will go through the PC (the pc will actually take care of sending a dialtone, etc...) am i correct, is this possible (to use the existing POTS infrastructure)?

The appliance was built in July and so needed some updating. I www.bagvapp.com So cutting to the chase here. All software updated nicely but when I started fooling with the kernel I hit a brick wall. The original is 2.6.24-r8. Apparently built with genkernel as it has just about everthing possilbe enabled. The original setup was rigged to boot with an initrd (from grub) title=linux-2.6.24-gentoo-r8 root (hd0,0) kernel /kernel-genkernel-x86-2.6.24-gentoo-r8 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sdb3 initrd /initramfs-genkernel-x86-2.6.24-gentoo-r8 vga=0x317 And originally used /dev/sda3 for root. It worked just fine. But none of my attempts to bring the kernel up to date have worked. All failing with a error message something like: `/dev/sdb3 is not a valid device'. But of course it is because reverting to the original kernel allows a successful boot. You'll notice I've since moved root from /sda3 to sdb3... expanding everthing. That is not the cause of the problem though since the original kernel boots just fine with the edit to /dev/sdb3 as root. I will post exact error messages in a bit but I'd gotten rid of the extra sources.. and was about to give up messing with this. I'm redownloading the latest gentoo-source and will post what ever errors occur with it. I'll build using the old kernel config as basis. And ditch the initrd.

Re: [gentoo-user] Re: Tragic kernel building for vmware gentoo guest on WinXP
You probably need scsi and scsi disk support compiled in as well. Everything
associated with accessing the device and the filesystem it contains has to be
compiled in to the kernel and not be a module. The initrd is loaded into
memory and loads the kernel modules (the ones you need to compile in), once
they are the root filesystem can be mounted. Without the initrd you can't load
the modules because they are on a device that cannot be read for lack of
support in the currently running kernel.

That's an LSI Fusion-MPT controller. Enable:
Device Drivers-[*] Fusion MPT device support-
* Fusion MPT ScsiHost drivers for SPI
Reboot. Have fun :P
I don't think thats the trouble... that has been enabled in every
kernel compile I've run trying to get a working config.
The original setup was rigged to boot with an initrd. How can I take
that initrd apart and see if there is some trick driver built into
it.
cp /boot/the-initrd-you-want ~/initrd.cpio.gz
gunzip ~/initrd.cpio.gz
Examine it's contents with mc or extract it with cpio.
But I don't think there's a trick driver or anything involved. You
don't even need an initrd if you compile the LSI driver in-kernel.
I just made in initrd for that kernel2.6.27-r5... and by god it
booted using the initrd so that initrd is loading the driver you
mentioned I guess.
I see now that even the original working kernel had LSI driver as
module ...so I'll try compiling into the kernel now as you've
suggested. Thanks...
You also need the filesystem driver built-in (ext3, Reiser, whatever
you're using.) An initrd is really only useful for generic kernels and
for bootsplash. I guess that means the appliance you downloaded was sub
optimal in the sense that nothing special or any kind of effort was
required to create it. A good appliance would have provided a slim
kernel with only what's needed compiled-in since VMWare has the same
hardware everywhere (that's the whole point of VMWare actually.)
Re: [gentoo-user] Is an Intel motherboard RAID better or worse thansoftware RAID?
Go areca, I have a coworker that raves about his. At my shop we have dozens of systems using 3ware and they have horrible preformance. --Original Message-- From: Pintér Tibor To: gentoo-user@lists.gentoo.org ReplyTo: gentoo-user@lists.gentoo.org Sent: Oct 15, 2008 6:41 AM Subject: Re: [gentoo-user] Is an Intel motherboard RAID better or worse thansoftware RAID? If you want to be sure your data is still readable in the event that your mobo dies and you can't find a replacement with the same fake RAID controller, stick with Linux kernel RAID. or buy a 3ware/areca/adaptec card, which is 100% supported.
