My answer was That makes sense, but I have no clue about how to do it. PAM (pluggable authentication modules for Linux) is generally how you slip some new check into the existing login (or other) auth process: http://www.linux-pam.org/ For e.g. there are PAM modules for LDAP directories and fingerprint scanners. Someone created a pam_confused module a few years back that will check passwords against a duress list and execute some pre-configured script when one is entered. It's not been updated lately but it shows roughly how you might do it: https://confused.googlecode.com/svn/trunk/pam_confused/readme.txt 1) What happens at a process level when one hits return after typing in a password? Is everything handled by the kernel? Where is this described? Check out the PAM faq and other documentation.

I've seen similar behaviour in a few situations: when the load on the box is extremely high it may take minutes (or tens of minutes if severely stressed) for the authentication to complete. I've seen this with runaway browsers and other processes chewing memory and CPU time. Typically in this case the password dialog is also slow to appear and the cursor may be laggy and unresponsive. The other one that comes to mind is a problem with authentication itself - if using network auth then a problem with the network or backend service may cause unlock delays. This should be less of a problem with local authentication. Finally, you might have a deadlock or task blocked on IO - for e.g. a kernel or driver bug or some storage device. I've seen this with file system bugs for e.g. when some IO never completes. Depending on where things are stuck you may be able to switch to a virtual terminal, log in, and debug from there.

File systems with mixed hash algorithms probably see a lot less testing than either one or the other but both options have been around for quite a while now. You can test this easily enough on loopback devices if needed and there's no real storage available and use debugfs to inspect the hash used for a particular directory, e.g.: debugfs htree foo Root node dump: Reserved zero: 0 Hash Version: 2 Info length: 8 Indirect levels: 0 Flags: 0 Number of entries (count): 2 Number of entries (limit): 124 Entry #0: Hash 0x, block 1 Entry #1: Hash 0x896bc308, block 2 [...] debugfs htree bar Root node dump: Reserved zero: 0 Hash Version: 1 Info length: 8 Indirect levels: 0 Flags: 0 Number of entries (count): 2 Number of entries (limit): 124 Entry #0: Hash 0x, block 1 Entry #1: Hash 0x7aa4fee4, block 2 [...] The hash versions are as follows: #define EXT2_HASH_LEGACY0 #define EXT2_HASH_HALF_MD4 1 #define EXT2_HASH_TEA 2 It's probably somewhat more risky than re-making the file system with the preferred hash and restoring but you could progressively migrate a file system over (or at least do some testing to see if it's worth it or not) by copying and renaming existing trees after changing hash_alg.

That said, you should check out Richard's suggestion as you may find that it's the many variant (up/smp/pae/debug/debuginfo etc.) sub-packages that are chewing up the time for you. If turning those off gives you an acceptable build time it's less invasive than munging the KConfig options to drop unneeded modules.

If it is not possible, what can I do? You can't really prevent a user from altering their environment (it's just an instruction to their shell which is under their control). If you need to keep a record of the commands that users are running you could consider either forcing them to use sudo if it's mainly administrative things you're interested in or use the audit subsystem to record what is being executed on the system (although you won't get full command line arguments). Other than that there are things like snoopylog that use an execve-wrapper to intercept calls to run commands and log full arguments. This comes with some overhead though and would reveal e.g. passwords typed in commands. Recent versions of bash can also be compiled with syslog support by defining SYSLOG_HISTORY but if your users are hooked on tcsh that probably won't help (I don't think it's enabled in the Fedora builds anyway).

Re: Plans for anaconda LVM/RAID support

What are the plans for LVM and/or software RAID support? Currently (F18 Beta TC2), it seems to be impossible for those of us who have fully allocated our storage to either (or both) of these technologies to install Fedora 18 at all. How would that work? Not the install, but the boot? Unless your BIOS knows how to handle LVM/RAID or you think you can shoehorn them into a boot sector, doesn't the boot need to be a normal partition? Mirroring is fairly straightforward since you just need a bootloader on each bootable disk. Some BIOSes are less helpful than others when it comes to booting with a failed drive but with the right system it's possible to have a reliable set up (most of my server boxes use MD mirrors for boot). Maybe I see too many dumb BIOS problems working with little ATOM and similar appliances, but getting them to boot anything seems an issue, and even with non-PC partitioning layouts I would expect to need one simple boot partition the BIOS could understand. The BIOS only really needs to understand where to load a first stage bootloader from - the traditional MBR protocol from the 80s (with a few extras bolted on here and there). Different BIOSes are better or worse in this area and some really are crap but that doesn't seem like a reason to not support those layouts for systems where they do work.

Description : GIMP (GNU Image Manipulation Program) is a powerful image
composition and editing program, which can be extremely useful for
creating logos and other graphics for webpages. GIMP has many of the
tools and filters you would expect to find in similar commercial
offerings, and some interesting extras as well.
GIMP provides a large image manipulation toolbox, including channel
operations and layers, effects, sub-pixel imaging and anti-aliasing, and
conversions, all with multi-level undo.

I guess the SCSI maintainers share that view since they've chosen to maintain the file (and the internal state it maps to) for some time.

An eSATA device should be able to suspend and resume properly (just like the other ATA devices in your system). Debugging it may be difficult unless you can get console logs showing what's happening during the suspend/resume cycle (serial console or possibly netconsole). What state is the device in following a resume? (/sys/block/sd*/device/state). Never knew about that file. Thanks! It only shows the SCSI state of the device but it can be a useful check when trying to narrow down the problem. If the SCSI layer was aware of problems it will often have set the state to 'offline'. If the device is out to lunch but the file still shows 'running' it suggests that there is a problem lower down and that the upper layers have not been informed of a problem.

That would normally also be reflected to some extent in CPU usage and process activity as shown in top (unless the problem was buffering them from a really slow network file system or something). I would think Andrew is correct - the load is most likely being driven up by processes that are waiting on I/O (D-state, aka uninterruptible sleep). On Linux the load average represents the 1m, 5m and 15m decaying average of the number of processes that are either runnable (waiting on a runqueue or actually executing on the CPU) /and/ the number of processes blocked on I/O. There's a fair bit of inaccurate information about the definition of the load average on Linux floating around - this comes from the fact that it's calculated slightly differently on the Sys V UNIXes and BSD vs. Linux. Traditionally only the runqueue length (tasks running or waiting to be scheduled) are counted as active. On Linux the number of active processes includes both tasks on the runqueue and tasks blocked on I/O; this means it's hard to compare the numbers meaningfully between BSD/Solaris and Linux even when running on the same hardware. Even well-known Linux magazines have managed to print entire articles that got this completely wrong in the past..

Since the original dd command: dd if=/dev/sda2 of=/dev/sdb1 Probably overwrote the file system that was on sdb1 (even though it was mounted - Linux/UNIX will not stop you from doing that) this is the most likely cause of the file system now being read only. If you give dd the path of a block device (for e.g. /dev/sda2 or /dev/sdb1) then it will write or read directly to or from the device. This is useful for copying file system images between devices but is probably not what you wanted here. The if= argument to dd is the input file - where to read from - and the of= argument is the output - where to write to. If this command ran for any length of time it will have overwritten the file system on sdb1. When creating an image in another file system the if= argument must be a device and the of= argument needs to be a path that refers to a location on the target file system. For instance, if I have /dev/sdc5 mounted on /home: # mount | grep home /dev/sdc5 on /home type ext3 (rw) And if I want to take an image of /dev/sda2 and store it in a file named sda2.img in my home directory I would run: # dd if=/dev/sda2 of=/home/bmr/sda2.img You need to do something similar but specifying a path that corresponds to the correct mount path for your sdb1 file system. When taking an image like this if is a device node in /dev and of is a path in the mounted file system. The reason your file system is now read-only is that when ext2/3/4 (or other file systems) detect an inconsistency with what's expected to be on the disk they will place the fs in read-only mode to prevent further damage. When the kernel started reading unexpected data from sdb1 it triggered this mechanism and aborted the file system. The file system on sdb1 is possible damaged beyond repair at this point so if there was nothing valuable on it already you are probably best off unmounting it and creating a new file system on the device. You should take some time to make sure you have everything correct this time and ask questions if you're unsure about the right commands to use but assuming sdb1 did not contain anything you want to recover you could create a new file system on it, mount it, and create the image with steps like the following: # umount /dev/sdb1[ ensure that the device is not mounted before proceeding ] This umount is probably the step you missed if you're still seeing read-only messages. # mkfs.ext4 /dev/sdb1 [ or mke2fs -t ext3 as Rick suggested - they will both give you the same result ] # mount /dev/sdb1 /mnt # dd if=/dev/sda2 of=/mnt/sda2.img This will create a new file named sda2.img in the top-level directory of the new file system on sdb1 that is mounted at /mnt. You can check that the mount command worked by running: # dmesg | tail EXT4-fs (loop7): mounted filesystem with ordered data mode SELinux: initialized (dev loop7, type ext4), uses xattr The device name will be different but you should see the mount message. If you try this and get any errors it's probably a good idea to check them out before carrying on. You can find an example of all these commands and their output in fpaste here: http://fpaste.org/XYNU/ Don't expect the output to be identical on your system but it should provide a guide (I've tried to highlight where you should see something different).

That was it. Thanks so much. It's now mounted successfully.
If you're trying to access partitions within a disk image it's usually
much easier to use the loop device and kpartx (from multipath-tools
but installed in a separate sub-package in recent Fedora).
Bind the image to a loop device:
# losetup /dev/loop0 /tmp/sda.img
# kpartx -a /dev/loop0
This will map partitions defined in the image as new device-mapper
devices with names like /dev/mapper/loop0p1 (for the partition one)
and has the advantage of supporting all common partition tables and
making all partitions available with a single command.
The resulting device-mapper devices can then be mounted directly as
any other block device.
Options are available to control the delimiter ('p' by default) used
and whether to include it always or only when the device name ends in
a digit.
When done you can tear down a (non-busy) map with:
# kpartx -d /dev/loop0
If that fails for any reason (e.g. you removed the partition table
while the maps were active) then you can clean up manually with
dmsetup remove name.
If you find yourself working with partitioned images a lot then it's
worth taking a look at libguestfs and guestfish - these are tools
designed for working with VM images but they should work just as well
with any partitioned disk image.

What format for the external disk filesystem do you recommend? And what the proper command to accomplish the formatting? If you need to access the backups from other non-Linux systems you may be better off with something like FAT32 (or even NTFS) as these will mount with no trouble or additional software on Windows and Mac systems as well as just about any Linux or BSD distro. You can store the backups in an archive format like tar which avoids the problem of mapping Windows/DOS ownership and permissions to UNIX notions. You could also look at UDF for this (it's supported by most modern systems now) but I'll admit I've never used it for writable volumes personally. If you don't care about compatibility with other platforms then you can chose from the available local file systems. This more-or-less boils down to ext4, xfs and btrfs these days. I'm using a couple of 1TiB drives in a pair of eSATA cradles (one at home, one at the office) with an LVM2 VG and XFS for this sort of use.

What format for the external disk filesystem do you recommend? And what the proper command to accomplish the formatting? ### End of Message from Paul Smith ### For best advice, more information would be helpful... For example, what's your retention policy? If you only need a single backup, and not historical backups *and* you are using LVM, you might consider just storing LVM snaphots on the backup drive. If you want a more flexible solution, you might try using rsync. Tar and dump are also still used. That would mean you would need to add the external disk to the system VG (in order to be able to snapshot logical volumes from the system). Generally that's a bad idea: if you're spreading VGs over multiple devices, especially with snapshotting, you typically want redundancy below the VG (i.e. mirrored or RAIDed PVs). You could also use LVM mirroring but then you're adding more complexity to the configuration. Things can also get ugly here if the backup disk is not going to be present at all times (for one thing if you do ever add one to your system VG you'll probably need to update the initramfs to ensure it contains the required modules for the external device). As far as your specific question, you need the name of the device, and I recommend creating a UDEV rule so that every time you plug in the external hard drivei, the partition you backup to gets the SAME link in /dev. This can save you from accidentally backing up to a thumbdrive that was also in the USB port, or maybe a different hard drive. Let's You can also just set a label on it - udisks and the modern desktop environments will then mount it under the media directory with a name based on the label and this will propagate to other systems you may use the device on without the need to copy rules files around the place.

I guess now would be a good time to mention that a volume snapshot != backup (see below), however, I've heard of snapshots sometimes being used to create a still or point-in-time copy of the system, which itself is backed up, since backups can take a considerable amount of time. Absolutely - this was the first practical use I made of snapshots with LVM1. It effectively lets you widen the backup window by only having to briefly pause services while the snapshot is created. The services then resume while the backup proceeds from the snapshot device. The cost is a performance impact from the snapshot (that is greater than a normal backup's load but which allows the service to keep running). Labels are okay, but I dislike them because they are abitrary. If labels are used, then don't used a label like backups because it's too likely to have a naming collision. Use a label like red-rover red-rover which is less likely to have collisions. Yeah, good point. I usually name things with my nick, then a roll and then an instance number or index (e.g. bmr_data2). It's not perfect by any means but does avoid many of the problems you mention. As far as using an external drive is concerned, for my backups, I opted not to do this, because when my house burns or gets blown away by a tornado, or is robbed (in which case the burgler is likely to take everything attached to the computer, too) that on-site backup isn't going to help very much; but the question was just about formatting a drive. I've had a setup for about six or eight years where I have three sites with DSL connections where I maintain systems. Important things get backed up locally via a daily cron job and periodically get pushed to one of the other sites (ssh with key authentication). It's very crufty and the scripts are pretty crappy but it works OK for the moment. Replacing it is one of the things I have vaguely in mind for the next year or so.

Umm, where, Jdow? I see five replies to the thread (not including this
one) but nobody mentioned alternatives or the virtual provides for
smtpdaemon/MTA which is kinda important in understanding how the
packaging of these components work on Fedora systems.
You can also use one of the simple smtp command packages (ssmtp,
esmtp) if you prefer not to have a receive-capable MTA installed on
the system. These provide /usr/sbin/sendmail and can be selected in
alternatives but do not provide smtpdaemon and cannot listen on the
network for incoming mail. They are a good choice for personal systems
or systems where you'd rather not administer a full-blown MTA.
For some reason the current ssmtp package doesn't list the
/usr/sbin/sendmail provide but it is included in the package. I
haven't checked to see if that would cause any problems while
attempting to remove any smtpdaemon.
Regards,
Bryn.

The parted documentation seemed to imply that resizing was supported, but at the end, no luck. It's possible but there are a fair number of steps involved. Use rescue mode (you'll need to in order to resize the rootfs and partition containing the PV). Boot into rescue mode and skip the file system detection option then use lvresize or lvreduce to shrink the file system volumes and their file systems (specify the --resizefs flag - otherwise you need to do this as a two-step process, first shrink the file system with e.g. resize2fs, then shrink the LV that contains it). Once you've shrunk the LVs you can check to see if the PV can be resized - use pvresize with the --setphysicalvolumesize option to set the the PV to the intended size. If this step fails it will be because there are still extents allocated to some LVs that are using the space you want to free up (this is unlikely with the default Fedora layout but can happen with more complex VGs or VGs that have a lot of allocations taking place). If this is the case you'll need to use pvmove to relocate those extents elsewhere (see the pvmove man page). Once the PV has been reduced in size you can shrink the partition. Unfortunately there's no good automatic support for this today. Parted still insists on resizing file systems (but doesn't work with most common file systems..). I normally use fdisk: you'll need to remove (delete) the partition you want to resize and then re-create it with the same starting offset. The easiest way to do this is to use sector mode (default now) and make a note of the value in the start column before removing the original. If you're using a GPT partition table then you can do the same remove/re-add routine with parted but I prefer fdisk for MBR partition tables (again, use sector units when modifying the partition).

Acceptable values range from -1000 (OOM_SCORE_ADJ_MIN) to +1000 (OOM_SCORE_ADJ_MAX). This allows userspace to polarize the preference for oom killing either by always preferring a certain task or completely disabling it. The lowest possible value, -1000, is equivalent to disabling oom killing entirely for that task since it will always report a badness score of 0.

It can still do a fair amount of nasty stuff. xhost local:subuser-id; sudo -u subuser-id does pretty well with current applications. You're allowing the local sandbox user to connect to the local X server so any process running in one of your sandboxes can start a connection to X and start looking for vulnerabilities to exploit. Due to the elevated privilege with which X runs this could include privilege escalations. There have been vulnerabilities of this kind in the past that allowed an attacker to quickly gain a root shell given the ability to connect to the X server. Now, if I'm going to my bank site, I do log out and log in as a different user, just to be extra safe. I think you'd be better off taking a look at Daniel Walsh's blog posts on confining X applications with the SELinux sandbox. The first post introduces and explains the general sandbox concept: http://danwalsh.livejournal.com/28545.html And the follow up looks at extending this to untrusted X applications using a temporary xguest account (with dynamic $HOME and $TMP) and the Xephyr X-on-X server to provide much stronger separation between the sandbox and the rest of the system: http://danwalsh.livejournal.com/31146.html Fedora already provides contexts to use with the sandbox such as sandbox_x_t, sandbox_web_t, sandbox_net_t etc. depending on the particular resources you want to allow the sandbox to access. The post discusses future improvements to simplify retrieving files from the sandbox when the application exits but I'm not sure of the current status of that work.

Hi all,
I have a cloned GCC git repository, on PC with 1.5GB of RAM and 3GB

When I run $git gc --aggressive, I will get after few hours an

compression using up to 2 threads. fatal: Out of memory, malloc

4.5GB of memory is not enough, what is that?
I wonder what git is internally doing, it seems to me as a pretty
non-optimal implementation. It is the first application I have
which has been killed by OOM killer.
Are you sure it got oom-killed? It appears to have just received a
malloc failure and quit. You'd expect abnormal termination via a
signal for an oomkill.
It would also be interesting to see the /proc/pid/{s,}maps output or
even a top snapshot of the git process before this happens - the
failing allocation was only for a little over 4MiB.
You might also get better results trying git-repack or git-fsck on
your tree first (git-repack on a cluttered repo can speed things up
greatly although I don't know if you may run into similar memory
consumption problems there).
With that said I'm not sure the behaviour is that out of line
considering the description of --aggressive:
--aggressive
Usually git gc runs very quickly while providing good disk
space utilization and performance. This option will cause
git gc to more aggressively optimize the repository at the
expense of taking much more time. The effects of this
optimization are persistent, so this option only needs to be
used occasionally; every few hundred changesets or so.
Regards,
Bryn.

The premature optimization bit is about choosing implementation clarity (expression) at the expense of execution speed over potentially confusing code that increases performance at runtime (optimization). The set of verbs and options systemctl accepts are the interface design. I think you are stretching things beyond the plausible to try to claim that a minor tweak to save 8 characters in a common invocation is UI design. It's just optimizing a common case. The difference between .service being a permitted implication VS a mandatory explication is one of interface and does not impact the implementation of the subsystem. Its the same argument as requiring that everyone actually type self in 'def foo(self):' in Python. I think its silly, others think it is more clear to be explicit to that degree when programming. But pushing systemd around from the command line is not programming unless its part of a script, and then the explicit .service extension is entirely appropriate. And speaking of scripting the shell, we've had this debate before a very long time ago. It resulted in the tradition of providing GNU flag extensions in addition to the old-style terse single-dash switches for the vast majority of command line tools. In scripts it can be polite (well, used to be considered polite, if anyone would remember today...) to write 'cut --delimiter=- --fields=2,3 foo.txt' instead of 'cut -d - -f 2,3', but both are perfectly acceptable and this provides a way to be explicit for posterity yet terse for practical reasons. No idea what point any of this is getting at. The systemd utilities support both long and short options where it makes sense to do so. It's almost as though someone designed it that way.. Have we forgotten that CLI *is* an interface and hence worth discussing? The I is there for a reason. And how on earth is it possible that we've forgotten what a cultural rule-of-thumb as important as premature optimization is the root of all evil actually means? Go ahead and discuss to your heart's content but flaming at people and calling a UI unusable and implying that the authors of that interface are not smart has no place in that discussion and should not be accepted.

That would be optimisation. A very smart programmer once taught us
that premature optimisation is the root of all evil. Perhaps the
author felt that other work was of higher priority at the time?
Besides, I would expect any Linux admin worth paying who found this
syntax so troublesome to be able to create a wrapper to suit their
preferred invocation style with minimal effort.
alias oldservice () { systemctl $2 $1.service; }
That took about as long to think up as it did to type. I am sure you
could improve upon it with little work.

Loaded: loaded (/etc/rc.d/init.d/httpd)

I'm also sure that upstream would be happy to review patches to
improve usability and merge them if appropriate.

As an example trying to figure out the camparative roles of grub2-mkconfig and grub2-install. The grub2-mkconfig command processes the templates in /etc/ and the options specified in /etc/default/grub to generate a new grub config file (Normally read from /boot/grub/grub.cfg and symlinked into /etc/ as /etc/grub2.cfg). It produces output on stdout. Redirect it to the file to update it. This is covered in the info manual, section 20 Invoking grub-mkconfig. Updating the configuration with grub-mkconfig is analogous to editing /boot/grub/grub.conf on prior releases. One would think that grub2-install wold have to run grub2-mkinstall but as far as I can see it doesn't. How confusing! The grub2-install command installs the grub2 bootloader components to a drive. It's exactly analogous to grub 1.x's grub-install script and is documented in section 19 of the info manual, Invoking grub-install. You only need to do that once unless something has overwritten it (like another OS installer) or you replace disks. You might also like to take a look at section 1.3, Differences from previous versions and section 3, and 3.1; Installation and Installing GRUB using grub-install. I can't stand the info manual format personally and I'd much rather have a well-written traditional man page but the information is there and quite clear imho.
