Re: [gentoo-user] {OT} rdiff-backup: push or pull?
On Wednesday, August 17, 2011 10:18:25 AM Grant wrote: You can seperate the backups by giving each system a different account where to store the backups. I'm not sure what you mean. The backups are all stored on the backup server. Each machine to be backed up has a different account on the backup server. This will prevent machine A from accessing the backups of machine B. This way, if one machine is compromised, only this machines backups can be accessed using the access-keys for the backup. And this machines keys can then be revoked without affecting other backups. That's a great idea. I will do that. Should that backup account have any special configuration, or just a standard new user? I would suspect just a standard new user with default permissions. Eg. only write-access to his/her own files. And I'd prevent that user account from being able to get a shell-account. A .bashrc with exit as the last or first entry is a nice touch. Especially if you set the permissions such that it works for the user but the user can never change that file. -- Joost

Yes: mke2fs -m 0 /dev/usb-drive Although a value 0 helps against fragmentation. And when rdiff-backup has failed because it ran out of space, regressing to the previous sane state will need a little free space. Good points. Should 10GB (1% of 1TB) do it? This I don't know. I use this value for large partitions of multimedia data, because I do not want to waste space (no matter how big the drives are, mine are always quite full), and performance should not be a big issue here. I keep the 5% default other partitions, like /home. BTW, you can also specify fractions like 0.5% if you like. I tend to leave it at default for most partitions. Only the ones serving the fileshare have it set to 0%. But these are on LVM partitions and I can increase their size when needed. Another thing: Be sure to have enough inodes on the file system, I have run out of them in the past. Not only once. I usually run out of these during installation time when I use ext2/3 filesystems for the portage tree. That's why I tend to use reiserfs for that. -- Joost

This implies that the new file data is not written over to the top of the old file - is that typically the case? Is it file system dependent?

I have an Atom 330 machine which is getting significantly worse
build-times than you. What make.conf options are you using? (Or are
you using something else to improve build times?)

Admittedly, my machine runs xbmc, which is a resource hog, and has a
fair bit of disk activity.
My CFLAGS are:
CFLAGS=-O2 -march=core2 -mtune=generic -fomit-frame-pointer -pipe
-mssse3 -mfpmath=sse
which date to before -march=atom, and having read a performance
article suggesting these. I note that the only practical difference
between the resultant gcc options is that setting -mtune to core2 adds
#define __tune_core2__ 1. I wonder what the practical difference is.
echo | gcc -dM -E - -O2 -march=core2 -mtune=generic
-fomit-frame-pointer -pipe -mssse3 -mfpmath=sse
I suppose, having looked into it this far, I'll merge gcc-4.5 to see
what effect -mtune=atom has.
(I'm not particularly interested in build times, but whether they're a
sign of poor overall performance ... )

Well i use an Atom D510, the core features seems to be quite similar to
yours, with the only difference, that D510 has a graphics unit added.
Here is my make.conf... how many threads are you using in gcc?

I've been doing it this way for most of this year, and I've watched DNS change in that time. For example: * I'm seeing far fewer errors logged complaining about EDNS. That's been nice. * I'm seeing fewer errors logged about bad lookups (FORMERR et al). Most sites which publish records seem to be doing it OK, although some CDNs, Google+ and Wikipedia *still* aren't doing it right. I've also switched from ATT ADSL to Comcast in that time (though my IPv6 comes from 6to4 in both cases), so some of those changes may be an ISP-level issue. -- :wq

[gentoo-user] /dev/sda* missing at boot
Hi, guys It is a shame, I know, but after several years using Gentoo, it is the first time I try to build a kernel without genkernel. And now I can't boot to that new kernel, it does not find (and really do not have a) /dev/sda* root partition (real-root); during the boot it stops, complaining about that, gives me the option to get a shell, from which I am able to see that there is no /dev/sda* . I have included everything SATA, so it looks like that is not a kernel problem, but a initramfs issue, I guess. What am I missing? Thanks a lot Francisco PS: my boot partition is sda2, sda3 is a swap partition, and everything else is in sda4. sda1 is not used (up to now) and this is my grub.conf : title Gentoo Linux 2.6.39-gentoo-r3 root (hd0,1) kernel /boot/kernel-genkernel-x86_64-2.6.39-gentoo-r3 ro root=/dev/ram0 init=/linuxrc real_root=/dev/sda4 vga=0x318 video=uvesafb:1024x768-32 nodevfs udev devfs=nomount quiet CONSOLE=/dev/tty1 initrd /boot/initramfs-genkernel-x86_64-2.6.39-gentoo-r3

The non-working port lights up the USB drive but the drive isn't picked up by the system in dmesg at all. I don't know if this is a hardware or software issue. - Grant - Grant

When I was building my PC, one of the USB ports on the front of my case didn't work. After looking at it closely, I saw that one of the pins on the port was bent inward on itself, so it never made contact when I plugged devices into it.

You might also consider enabling SCSI-generic (disk), which would catch ide-emulated disks and put a scsi interface around them in the kernel. But it might well shove a generic driver in before the specific one has a chance. The docs warn of this. Finally, check that it's coming up as /dev/sda and not something like /dev/sdb. Good advice (if I may presume).

Re: [gentoo-user] {OT} rdiff-backup: push or pull?
You can seperate the backups by giving each system a different account where to store the backups. I'm not sure what you mean. The backups are all stored on the backup server. Each machine to be backed up has a different account on the backup server. This will prevent machine A from accessing the backups of machine B. This way, if one machine is compromised, only this machines backups can be accessed using the access-keys for the backup. And this machines keys can then be revoked without affecting other backups. That's a great idea. I will do that. Should that backup account have any special configuration, or just a standard new user? I would suspect just a standard new user with default permissions. Eg. only write-access to his/her own files. And I'd prevent that user account from being able to get a shell-account. I created the backup users and everything works as long as the backup users have shells on the backup server and are listed in AllowUsers in /etc/ssh/sshd_config on the backup server. Did I do something wrong or should the backup users need shells and to be listed in AllowUsers? Should I set up any extra restrictions for them in sshd_config? Should I set passwords for them? - Grant A .bashrc with exit as the last or first entry is a nice touch. Especially if you set the permissions such that it works for the user but the user can never change that file. -- Joost

And what type of shell are you dropped into when then happens? Is it a single-user mode shell or grub (or something else entirely)? Also, while you're booted into the livecd/dvd/usb and you chroot, try lspci -k and check to see what modules/drivers that lists as installed and see if you have them enabled in your config. - Matt
Re: [gentoo-user] {OT} rdiff-backup: push or pull?
I'm setting up an automated rdiff-backup system and I'm stuck between pushing the backups to the backup server, and pulling the backups to the backup server. If I push, I have to allow read/write access of my backups via SSH keys. If I pull, I have to enable root logins on each system to be backed-up, allow root read access of each system via SSH keys, and I have to deal with openvpn or ssh -R so my laptop can back up from behind foreign routers. The conventional wisdom online seems to indicate pulling is better, but pushing seems like it might be better to me. Do you push or pull? I would push, to be honest. What can be done about the fact that any attacker who can break into a system and wipe it out can also wipe out its backups? That negates one of the reasons for making the backups in the first place. Should private SSH keys be excluded from the backup? Should anything else be excluded? - Grant

What it is capable of doing is in the .config file. If genkernel doesn't give you a .config file - I've never used genkernel so I don't know what it does - then assuming you have the feature turned on you can get the running config using zcat /proc/config.gz. Save that to a new .config file, put it in the kernel source directory and you should be good to go. You can also use zcat /proc/config.gz on the install CD kernel if yuo boot from that. Save it to a disk and use it as the basis for creating your own config. HTH, Mark

(Some motherboards let you choose between IDE and RAID, where RAID is AHCI mode. Others call IDE mode 'legacy', and still others might actually call the AHCI mode 'AHCI') That is if the BIOS will allow you to do so. Some BIOSes, for example some Dell servers, will only run SATA in emulation mode despite the chipset supporting AHCI. The only option they give for SATA is enable/disable.
