Personally, I would recommend pulling an rsync (databases and such might cause a hiccup with that) of one of them to a nonessential system and testing updating there, building packages (assuming matching use flags, etc, across your systems), documenting the pitfalls you run into as you go. After you're up to date there, run through and test it again from a base copy, then test the actual services to ensure changes to them don't hose your environment's configuration, and once that's good, it then depends entirely on what failover, or downtime allowances you have available. If you have no failover to rely on, and can't afford enough downtime to update the system in place from the packages you've built, clone each off, update, then migrate the changes that've occured in the time between... time consuming, and requires a lot of care, but doable. -- Poison [BLX] Joshua M.

Re: [gentoo-user] Gentoo speed comparison to other distros

While I'll start by backing up everything said by others regarding the differences being nearly negligible in a truly equal test, same feature set from source vs the feature set provided by a binary distro, and even a loss in terms of total time when you include the compile times involved, I do have a bit of anecdotal evidence in Gentoo's favor. On the majority of x86 or x86_64 hardware there's very little room for across the board gains in performance over otherwise standard cflags. On slightly less 'normal' hardware, like, say, an Atom N270 based netbook with 1GB of ram, however, a few cflags go a *long* way towards having a usable system. My Mini9 shipped with a variant of Ubuntu that's actually built with general optimizations to make it usable on that hardware, and having run the same version of Ubuntu without those optimizations for a day or two on it, the amount of stutter and stalling was almost unbearable. Then, with the help of a desktop (or three) to handle the bulk of the compilation, I moved to Gentoo on it. I hadn't sorted out what cflags would be best, and simply built what I needed to get back to work on it with fairly minimal use flags, and I was rather frustrated to find that it still ran worse than the factory install, once programs had started (though that process was noticeably faster, as it generally is with so much less running in the background). Once I adjusted to the appropriate cflags, the stutter cleared up, things didn't stall frequently, and the system was simply more responsive. I could even watch flash videos full screen without it stuttering, which I'd given up on as a possibility on the system. A vast majority of the gains I saw were simply from clearing away the 80% of Ubuntu's features I have no use for, but when you have a processor that approaches things just a little differently, like an Atom, you really can gain a bit from letting the compiler put things in an order the processor will agree with better. -- Poison [BLX] Joshua M.

If it's a system used exclusively by people with a common choice of locale, it potentially saves on per-user configuration. If it's a system used by people from around the globe, it can break their expectations of how a 'default' system should act before they configure their own account for their own locale. I believe, in the event a locale isn't specified, it defaults to POSIX. Of course, all of this also depends on the software involved actually honoring the setting, but luckily enough (for selfish people like me, that is), US English tends to be the de facto standard even when things don't honor the locale.

I have libraries available from system B and that is all that I have. I need help on getting this done. I guess gcc versions are the same and as well libgcc_s.so.1 shared library. My questions are: Can I pull those libraries from system B and use it in compilatin process? Would that work? I would still need to get include source files of that version, right? Is there some archive site where I can find so old version of linux kernel source? One thing that pops in to my mind is also trying to find gentoo stage 3 tarball of the kernel version 2.6.16.27 and compile the program there...I tried to search that but no luck in that... Any help would be welcomed! Well, you could use a chroot on system A to build it against an older copy of the library. I can't find a stage3 with that range of glibc, though if you can still track down sources to piece together a toolchain, LFS 6.2 [1] is from right around that time frame (around '06-'07). If anyone has a 2007.1 range stage3 laying around, though, all the hard work's already done for setting up a perfect chroot as long as it plays well with a newer kernel (or if you can do the build in said chroot on system B), I've had issues with a too-new set of libraries on older kernels more than once, not sure I've tried the other direction.

In my completely uninformed guess... a) tmpfs automatically 'cleans up' every reboot, making sure old folders aren't sitting around stale even if something did go wrong, and/or b) it's guaranteed writable for the service that needs to make those mount points.

Two things come to mind, given some recent trouble I've had on the
radeon side of the coin here, and with an intel system or two in the
past. The DRM related drivers seem to be prone to misbehaving when
they're not configured as modules. I haven't managed to sort out why,
so you may see if a change there helps, though it'll likely cause mode
changes throughout the booting process. The second thing that comes to
mind is that you don't include any relevant entries from glxinfo
(glxinfo | grep ender) or Xorg.?.log (notably anything flagged as an
error, 'grep EE /var/log/Xorg.0.log' grabs that, plus a bit of cruft),
notably from a session where things aren't working properly, as the
majority of issues trace back to direct rendering being disabled due
to some incompatibility that gets noted in the log (often in
delightfully cryptic prose).

Mar 28 13:24:01 lumby pppd[16825]: secondary DNS address 75.153.176.9
But whatever is in resolv.conf is overwritten with blanks AFTER I
connect. Which creates this odd situation where I can ping numbers,
ie, 8.8.8.8 but not com, net, org etc.
Once I connect I have to echo the DNS addresses into resolv.conf
before I can reach anything.
Also, I notice whenever I set up a route to my router those numbers
get wiped. Is that the default behavio(u)r?. NB, I have nothing in the
way of services other than ppp configured at all. Maybe later after I
sort it all out I'll rig up something automatic.

If I recall, this was my guess as the real problem you were running
into. As for what's making the last change to /etc/resolv.conf...
aside from kernel-level auditing, there's nothing I'm aware of that
can tell you. Since /etc/ppp/resolv.conf is correct but
/etc/resolv.conf isn't, one of three things is happening:
a) 40-dns.sh is running, making the changes it needs to, and they're
being promptly overwritten by something else... unlikely and
excessively hard to diagnose,
b) 40-dns.sh is running but isn't actually updating /etc/resolv.conf
properly... it looks fine, matches the default I have here (which
works on my pppoe setup at least), but could happen if one of the
assumptions it makes is wrong (or if, say, if [ $USEPEERDNS ]; is
coming up false), or...
c) 40-dns.sh is not even running, meaning /etc/resolv.conf never gets
updated by pppd... this would have been my first guess, except for the
fact that /etc/ppp/ip-up just outright sources all *.sh in
/etc/ppp/ip-up.d/ so... shouldn't be that (and I saved myself from
looking a bit silly, checking that beforehand).
The first step to tracking it down would probably be stepping through
that script and comparing it to your situation. Does
/etc/resolv.conf.pppd-backup exist? If so, it *is* at least making
changes to the original. I recall usepeerdns is set, so is
/sbin/resolvconf an existing, executable, file? If not, and since they
differ, I suspect it's failing somewhere in merging them. You might
add some echo calls writing out to a file in /tmp to 40-dns.sh so you
can track what, if anything, it does (and what values it's using in
the process).

If your root has enough free space to hold all of /usr already, without any resizing, you actually can do everything with only a single reboot along the way (and while that, too, *can* be avoided with a lazy unmount in place of the reboot [see notes at the bottom if you're feeling adventurous], I don't dare test it when a reboot's far from likely to hurt me), as long as you can resist making changes to files in /usr between starting and your reboot. The difficulty you run into is that you can't copy from /usr/* (the data on the usr partition) directly into /usr (a folder acting as a mount point on the root partition). What you *can* do, however, is bind mount your root partition somewhere else, and your usr partition too if you like, make the copy (using tar, rsync, or cp with the appropriate flags to preserve all the important details), adjust fstab, and then reboot into the adjusted system, after which, you can go about pondering what to do with your old /usr partition. Incidentally, this general method also works fairly well for taking snapshots of a live root partition (accepting that the contents of anything prone to change mid-copy could be anything, like /tmp, most of /var, bits of /etc), catching the static files hidden by mounting done at boot time, like the base set of device nodes in /dev too... As root, obviously, and you may include --acls or --xattrs on the rsync call, if they suit your system's needs (I have quite a bit turned off on the machine I'm testing this on as I write it up): 1) make backups and... 1.a) verify backups... consider this my disclaimer... 2) mkdir /mnt/root-bind/ /mnt/usr-bind/ 3) mount --bind / /mnt/root-bind/ 4) mount --bind /usr/ /mnt/usr-bind/ 5) rsync --archive --hard-links --sparse --progress /mnt/usr-bind/ /mnt/root-bind/usr/ 6) edit fstab ... 7) cross fingers and reboot ... 8) rm -r /mnt/root-bind/ /mnt/usr-bind/ While 9 can be done before the reboot, this way doesn't depend on fighting with unmounting outside of the reboot itself.

I have an external 1TB eSATA drive which is therefore large enough

/dev/md3 is a second Gentoo installation that doesn't need to be
backed up at this time. md6 is an internal RAID used to back up md7
daily. It doesn't need to be backed up, but if the machine totally
failed killing all the drives that wouldn't survive so currently I
back up md126 to md6 daily, and then back up md6 weekly to an external
eSATA drive.
What I'd like to do is clone
1) /boot (sda1) including grub and everything required to make it bootable
2) back up the system portions of dev/md126 (/ )
3) Add some swap space on the external drive
4) back up /dev/md7 which is all of my VMs
5) back up /home to a separate partition on the external drive
6) back up some special things like /var/lib/portage/world and
/usr/portage/packages
My thought is that this drive is basically bootable, but over time
gets out-of-sync with the system. However should the system fail I've
got a bootable external drive with all the binary packages required to
get it running again quickly. However I can always boot the drive, do
an emerge -ek @world, and basically be back to where I am as of the
last backup.
The external drive will look something like:
/dev/sdg1 - /boot
/dev/sdg2 - swap
/dev/sdg3 - / (not including /home, /usr/portage/distfiles, etc)
/dev/sdg5 - /usr/portage/packages
/dev/sdg6 - /dev/md7
etc
I will of course have to modify grub.conf and /etc/fstab to work
from this drive but that's no big deal.
What are folks best ideas about how to approach doing something like
this?
Thanks,
Mark
Hi,
Why don't you something like bind mount the folders you want to copy
and rsync them to the eSATA disk, after creating a similar partition
layout on it. Remember to exclude system files like /proc/*, /dev/*
and /sys/* as well as the ones you want to exclude yourself from the
rsync. When you want to sync the clone again just do the same again
and rsync the changes.
Regards,
Derek
As an added note on this, rsync's --one-file-system (-x) flag is handy
for avoiding grabbing unneeded things, but will typically leave you
without the base few device nodes needed to boot the backup, those can
either be grabbed from a stage3, or created with (courtesy of Linux
From Scratch's section 6.2.1. Creating Initial Device Nodes):
mknod -m 600 ${backup}/dev/console c 5 1
mknod -m 666 ${backup}/dev/null c 1 3

All my drives says this from fdisk: Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Neither fdisk nor hdparm seem to get the correct sector size, at least not always. That's what I read somewhere (and not only once), and it's true for my own 2TB drive which I know to have a 4K sector size. I'd say you have to look up the specs on the vendor's web size to be sure. So it doesn't matter where the first partition starts? If you have 4K sectors (and not a Seagate drive with SmartAlign [*]), it does.

In fact it did run those tests, and it settled on a value of, I think, 16MB blocks. It then ran a read-only test of the entire file system, and only then started copying it. As it was moving the partition upwards by about half its occupied size, there was considerable overlap. That must mean that it started with the highest-numbered block and worked steadily (very!) downwards. I don't know where in the partition it ran its speed tests, but on a partition that occupies almost all the physical disk, as it did, there must be a considerable speed difference between its two ends. -- Rgds Peter Linux Counter 5290, 1994-04-23 There probably is a fair chunk of difference in maximum speed the disk can work at on each end (I've even seen around a 20MB/s difference on several 160GB drives I've dealt with), but outside of some older drives that've been heavily abused in their lives, I'm not sure I've seen a sata drive that I've used my usual drive test (MHDD on a Hiren's bootable USB) on register below around 60MB/s on the slow end, and USB2's *theoretical* limit is 480Mb/s (60MB/s) ... real-world implementations rarely reach, let alone top, around 40MB/s, so disk speed variation across the disk is an unlikely source of the slowdown. More likely, it's the fact that parted has to start from the end, and work its way backwards, reading, writing, and verifying in separate rotations of the disk with no benefit from the drive's ability to stream a larger block into cache, since the whole process is backwards compared to the streaming read most drives are optimized for. Of course, this is all off the cuff conjecture on my part, including my assumptions about how parted approaches the whole task... mixed with a bit of anecdotal evidence on my end... but, makes for amusing conversation and contemplation, if nothing more substantial. I will point out that the newer advanced format WD 500GB blue's I've worked recently with pulled a consistent 120-110MB/s speed from end to end... when their older 320s usually peaked at around 85 or so. -- Poison [BLX] Joshua M.

I tested it and it really didn't make much difference. Most of the time it was slower but a couple times it was faster but only by a few seconds. I guess drives are just a lot faster nowadays or at least fast enough. I dunno. Dale :-) :-) I would hazard a guess here that, rather than it being a benefit from improvement in drive speeds, it's moreso an improvement in the kernel's file caching. As I understand it (likely incorrectly) tmpfs essentially does little more than inject the given file into the filesystem cache, with a 'keep this here' flag attached to it. As files are accessed on the disk, they're pulled into the filesystem cache anyhow, and they stay there as long as they're being used and there's room to keep them. With tmpfs, every file you put into it stays until explicitly removed, wheras letting the kernel handle the selected list of files in the cache only keeps the ones the kernel feels are worth keeping. I am curious, though, whether *not* using -pipe will actually improve performance when building in tmpfs, as you're already sidestepping most of the overhead of creating files with tmpfs, so piping data rather than using intermediate files just creates extra memory usage overhead (which, while cheaper than disk i/o and filesystem metadata updates, is still overhead). Another likely source of performance loss in using tmpfs over physical disk to hold the build is that, by design, tmpfs occupies a portion of the filesystem cache. During a build, every header imported, every library linked, and every process that runs to make it all come together gets touched. When you touch files on disk, some or all of them get pulled into the filesystem cache, so keeping the entire build tree in the cache may well leave more frequently used files being dropped from cache to trade back and forth between one another. Again, all of this comes with a I likely have no idea what I'm talking about, but it sounds convincing disclaimer. :-) -- Poison [BLX] Joshua M. Murphy

I recommend trying out SystemRescueCD to experiment with PXE booting for the client and server. That sounds like exactly what I need. So, I could set up a Gentoo server and a bunch of completely diskless clients which would all PXE boot from the server? Would the clients basically each control a different virtual terminal on the server? Each machine can pull a copy of the master boot image to make updates a lot simpler. The SystemRescueCD PXE boot mechanism just pushes out a copy of the CD to all the machines to boot them. to update the boot image just update the files in one location to update all machines. the machines act as separate fully functioning machine. Check out http://www.sysresccd.org/Sysresccd-manual-en_PXE_network_booting to see how to setup the PXE boot environment. I think I get it now and it sounds great, exactly what I'm looking for. Everything can be done in RAM, no disks required? Can PXE boot be done wirelessly? Maybe only if the wireless is onboard? I tried to Google this but the info returned is terribly outdated for some reason. Do you think SystemRescueCD is the best boot image for clients that only need a browser? What sort of machine would work well as a client? Should I just put together a bunch of motherboards with onboard video and ethernet, CPUs, RAM, PSUs, and small cases? Is there a prebuilt system that works well for this? Maybe an ARM-15 system as Tampa Bay James referenced, although I think that isn't released yet. - Grant Well, the first thing you need to decide is whether you want each client running that browser locally, or whether you want each client to merely provide an interface to the server, and every user's browser (and every other application) running on the server itself. If your clients boot, then run all their own software locally, your server's under only under load during boot-time and your clients need to be able to handle that work (not much, but it's more than nothing, just try running a modern Firefox on 64MB of ram). On the other hand, if your clients merely boot into a remote connection to the server, a la VNC or NX, the client does *very* little locally, can run on next to nothing hardware-wise (a true 'thin client'), and the entirety of the workload is offloaded to the server. If you want responsive 'eye candy', 3D graphics work/play, or any form of particularly 'smooth' animation, you will want that work to be handled on hardware closer to the user (requiring a far faster processor, more ram, a capable video device, and likely local storage for swap at the least), while serving up a simple browser to the user is far more forgiving. As for wired vs wireless, true hardware PXE booting is generally limited to wired scenarios, but it would be entirely possible (though not truly 'diskless') to deploy a minimal kernel+initramfs that handles initial booting, joining WiFi, pulling down of the system 'image' from your server, and handing control off to that in the same way your run of the mill kernel+initramfs loads hardware drivers until it can find the harddrive, attaches to the root partition, and hands off control to init from there. Changes to the wireless configuration would require directly visiting each client, and client-side kernel or initramfs updates easily could as well, if things don't go as planned (but, since all the user-side software is either run on the server or loaded from it at boot-time, changes to the client's loader shouldn't be frequent). There's also the option of pre-made hardware thin clients that typically boot from internal flash and simply provide a remote interface to a central server (though most are geared towards RDP or Citrix), and some are even WiFi capable. -- Poison [BLX] Joshua M.

With regard to the trouble you're seeing, I've had more issues than I can clearly recall with bridging and wireless cards when I've tried, and it may be a similar roadblock that you're running into there. If you don't need each VM to be 'local' to the network you're on, you might be better off using NAT to interface the internal network of VMs with the outside world. 'promisc' means that the interface is in promiscuous mode. Promiscuous mode recieves every ethernet frame to handle them rather than only accepting frames that are targetted for the interface's MAC address, which then allows all of that traffic to be forwarded across the bridge to other networks.

I read that but still would love to here of someone else's experience.
From that link tho, it sounds . . . interesting.
I emerged tmux a couple of hours ago and have been playing around with
it. It looks like fun. I have a 24 LCD monitor. I prefer console text
mode for non-graphic stuff (e.g. email). Here's what I've done so
far...
1) grep 1280 /var/log/Xorg.0.log
This gives me a list of 1280xwhatever modes that my monitor supports.
In my case, it's 1280x720 and 1280x960 and 1280x1024.
2) I entered the line
CONSOLEFONT=lat1-14
in /etc/conf.d/consolefont
3) and also video=1280x720 in the append line of /etc/lilo.conf
4) I entered the line
set -g prefix C-a
in ~/.tmux.conf because every site on the web that reviewed it said that
was the way to go. Apparently, the developer uses {CONTROL-B} as the
default hotkey to avoid colliding with {CONTROL-A} which screen uses.
But everyone agrees that {CONTROL-B} is badly placed on the keyboard.
5) Then I rebooted
The text console mode is now 1280 pixels x 720 pixels as per the
video= parameter. The consolefont sets 8x14 (EGA) font. A bit of
division gives...
1280 / 8 = 160
720 / 14 = 51 plus a bit.
So I have a 160 x 51 text console. I fired up tmux, and split the
screen vertically. I now have 2 panes. The first one is 80 x 50 and
the second is 79 x 50. This is after allowing for the vertical dividing
line (one column) and the status bar at the bottom. The 14-pixel high
font is quite nice. And on a 24 monitor it's very readable. If you
prefer, you could go with the 16-pixel high (VGA) font. That gives 720
/ 16 = 45 rows, or 44 working rows plus the status line. Both text
pages are in portrait mode, i.e. they're higher than they are wide.
Sort of like 2 facing pages of a book. This could be useful for
editing a program in one pane, and then compile and execute in another.
If your eyesight is better than mine, you could try video=1280x960
and 16-pixel high font, which will give a 160 x 60 text console.
I like it. One of these days, when desktop monitors hit 30, I'll set
the video to 1920x1080 and have 3 pages across.G
I installed it too. It seems a lot like screen to me and screen seems to do
what I need. I did hit ctrl a several times tho. lol I was wondering what
would happen if you started tmux then started a screen session inside it.
My 22 LCD monitor is 1920x1080. Since my glasses are sort of old, I would
rather have a slightly smaller screen. I need new glasses for sure.
Anyway, I got everything set up for this size now.
I may play with tmux some more tho. I do like the little status thingy at
the bottom. I had that on screen on my old rig but forgot to copy it over
to my new rig.
Thanks for the post and the tips.
Dale
:-) :-)
I've just taken a day to play with it, if only a little, yesterday and
I have to say, I do like it so far, but I'll have to put some work
into mapping keys to match what I'm used to from using both screen and
ratpoison together. The lack of escape key+space to jump to the next
by default was the biggest catch for me so far, and I also generally
use key+w for a rapid reminder of what's where when I'm hopping
through larger numbers of terminals, a habit that slows me down a lot
when I walk face first into a selection menu rather than just a quick
flash of information, so it's a habit that would need to change. I
don't often use the split, even screen's horizontal, as it doesn't do
much good for me on a little 9in screen.
In the end, it's very promising, has a lot of great information that'd
take a fair amount of configuring to get from screen (And as much as I
don't like the binding for that menu, I do like the feature), but
would require me either breaking habits or working around them with
the configuration quite a bit. I think, were it not for ratpoison
taking screen's shortcut keys wholesale with only a few additions, I'd
be a lot quicker to pick up tmux. As it is, I suspect I'm as stuck on
my habits as a heavy windows user is theirs. Screen on it's default of
control+a, ratpoison on a straight windows key tap.

Otherwise you end up in the situation that you have started one system update (or software install), have a build failure for whatever reason, and then can't complete the same one due to changes in the local copy of portage. You can still use emerge -sync instead of a home brewed script. In make conf, set SYNC to localhost, then in your cron job, do SYNC=some gentoo rsync mirror emerge --sync So, even if your system fell into the first situation - where it is fast enough - then I would still recommend doing the little extra to run as the second situation. It's just far easier to maintain. I've been using a single portage tree to serve a LAN and for use by the host for years with no hint of any of the problems you suggest. I just make sure the cron job on the server syncs earlier than the rest of the LAN and everything is up to date. I used to have four computers a good while back. Back then, I synced my main rig then synced the others off it. This was several years ago. I don't use a cron job or anything to do this, just some old fashioned typing. I don't recall ever having trouble with it syncing to my main rig. Did I mention it was a very old Compaq 200MHz CPU machine with a whopping 128MBs of ram? Thing looks like a filing cabinet. To me, it seems the OP is making something complicated when it is just not needed. If you want to use cron jobs, set the main rig to sync a hour before the others would be set to sync against it. If the rig that syncs to Gentoo servers is to slow, set them two hours apart. From my understanding, you get the same tree all the way around. Giving some more thought, I once put /usr/portage on nfs. I sync once and all the systems used the same copy of the tree. The other way worked out to be easier tho. I seem to recall the need for running emerge --metadata too. That took a while on the old Compaq. lol Dale :-) :-) The trick I've been using for... a couple years now, across various machines (no cron involved), is syncing one box that shares portage *and* my distfiles on nfs, portage R/O, distfiles R/W, then when it's done syncing and starts its own metadata update, hop across all the others and do an emerge --metadata. Once each one finishes, run through their individual updates. Because distfiles is shared, and portage's distfile locking is done right... I download each tarball of sources exactly once, even when 5-6 machines might share the same one. I've been quite pleased by that... even more handy is the shared git pull of wine that I build against on 3 different boxes (I tend to stagger those rebuilds though, haven't risked finding out if that would clash). -- Poison [BLX] Joshua M.

Re: [gentoo-user] High load, idle CPU?

Today, while trying to create a new postgresql database I noticed that certain system operations seem to take ages. Normal work on the shell works just fine but for example accessing the postgresql server through psql, restarting tomcat, postgresql or zope all show the very same behavior: Execution freezes, the load average climbs to 1-1.9 and after a few minutes (maybe longer) the task finishes correctly. During all this time, top reports that the CPUs are 100% idle. Other services, for example rsyncd or openvpn, work normally. I also tried restarting the VM. Shutdown took maybe 10 or 15 minutes. Booting was much faster with only a few minutes until all services were up and running. However, it didn't solve the problem. So, my question is: How can I find out what is causing this? Can I somehow trace it? Find out why a process waits? Keep in mind that this is a virtual server. I have no control over the kernel. Oh, and before you ask: The only recent update was rkhunter from 1.2.9-r1 to 1.3.4-r2. I also enabled the chkrootkit weekly cronjob. Thanks in advance!

If, by some luck, I've downloaded a fresh Linux ISO where binaries do not include the above two strings followed by commands, after I run an update the updated binaries suddenly contain the above two strings and other, what I believe to be, rogue strings. I've avoided the possible infection with an OpenBSD install, yet all the Linux installations and burned ISOs contain binaries with the above two strings followed by commands. Search using find within your bin and sbin directories for those two strings and see how many positives you find. Now use a text editor like vi or gedit and search through the gibberish, locate these strings and isolate the commands, if any, which follow them. Searching for gmonstart, gmon, registerclasses, jv, etc. variations of works. If you find results in your binaries, please copy/paste the commands following the gmonstart and jvregisterclasses strings so I may compare them to mine. I've purchased Linux CDs from brick + mortar stores, downloaded ISOs from different physical locations and found some CDs contained these strings in the binaries and one or two rare ones did not, but when installed/updated on a network connection the binaries replaced in the update process would show these strings!! These strings are not alone by themselves in the binaries they follow with commands with a @ mark before each command. Google results are vague, some suggest shell backdoors, every Linux user I've asked to date calls me paranoid while at the same time this knowledge comes as a surprise to them, too, when they search their binaries and find the same strings. I'm amazed by how quickly some rush to judgement and call you a paranoid for being curious about the files on your system. The strings may/may not be common, but in comparing commands which follow these strings I've noticed some which seem down right malicious! Maybe they're right, I'm just paranoid, but what am I seeing and why are these strings so common across Linux distros binaries, esp. the Jv (java?) reference? Please, any help? They're so common because they're binaries compiled with the same compiler against the same libc implementation, for the most part, and there will *always* be very similar strings resulting from BOTH of those states across anything they've had a hand in. Yes, of course, it's reasonable to be security concious, but both of the links I found for those strings are first page on Google. There's also the confusing fact that you look so heavily at the binaries while failing to take a look at the things that would be sensible reasons for the same strings between them... and grep is your friend if you're going to do any sensible auditing... you have... 1) Their own source code (may or may not have a reference) 2) Toolchain (and, really, it's the source code for these you'll want to look through) 2a) Compiler - gcc suite 2b) Linker - ld from binutils 2c) Assembler - Also binutils 3) Libraries - Anything *all* of them link to. ldd is an amazingly handy tool... 3a) libc.so.6 - glibc 3b) linux-gate.so.1 - part of the the kernel (not a real file on the system) 3c) /lib/ld-linux.so.2 - runtime component for the linker (which would be ld from binutils) And... when your own phrasing of things shows you don't even know *what* these two strings you found *do* or are *really* related to... cross posting to gentoo-security is really not necessary, though I can't guarantee the actual security experts on that list would agree...

Re: [gentoo-user] Broken upgrade from udev troubles.
On Wed, Dec 16, 2009 at 10:07 PM, Tom Bennet twben...@gmail.com wrote: I spent the day recovering from a Gentoo upgrade, and thought I'd document the experience in case it helps someone else. I'm running a custom kernel 2.6.25-gentoo-r7 on amd64, though I don't think the rarer hardware is relevant. I tend to put off upgrading my Gentoo box because anytime I do, something breaks. I'm afraid I haven't changed my opinion about that. Anyway, I did emerge --update --deep world and plugged my ears. Some 600-odd packages (and a few simpler problems) later, the system seemed to be doing okay. So I thought I'd see if it could survive a reboot. No, it couldn't. On boot it failed checking the root file system and dropped into the repair shell. The reason the fsck failed is that the root pseudo device file /dev/md0, didn't exist. The root file system was actually, fine, though. Inside the repair shell, I could see all the files from my root, but there wasn't much in /dev. (I have the md stuff compiled in to the kernel, and don't use an initrd, so it wasn't an initrd problem.) Short Solution The problem was with udev, the facility which automatically populates the /dev directory. During the upgrade, emerge noted that my kernel version was a bit early, but acceptable. What was missing, apparently, was the signalfd syscall, which that kernel version either doesn't have or I hadn't configured. Apparently, udev has only started using signalfd recently, so the solution was to downgrade to an older version of udev (udev-141 to be precise). What I Actually Did To Get There Of course, I didn't know that at first. Just had a fun unbootable system. I might have been able to simply emerge the downgrade from the repair shell (the network did come up), but I didn't know to try that yet. I figured I wanted to find some way to make the system boot. Since the failing file check is done from /etc/init.d/checkroot, I added a mknod command to create the device node before trying to run the file check. At the start of the start() method: if [ ! -e /dev/md0 ] ; then mknod -m 0660 /dev/md0 b 9 0 fi It's a hack, not a solution, but it did make the system boot, to a rather crippled state. Since there were a lot of devices missing, a lot of services wouldn't start. (If you're using a more boring root partition, it might be something like mknod -m 0660 /dev/sda1 b 8 1) So I had managed by now to gather that udev wasn't working, but I didn't know why. My first thought was to try /etc/init.d/udev start, to see if it would start. But it told me that the script is written for baselevel-2, and I shouldn't use it on baselevel-1. Following a bit of googling about what the heck a baselevel is, I gathered that I was using baselevel-1, and so the service wasn't supposed to be started that way. So it wasn't a bug that it wouldn't start that way. Another page suggested trying to run it directly, with /sbin/udevd --daemon, which gave the message error getting signalfd. That told my why it didn't start. This message was also in the logs, but for some reason I didn't look there until later. So back to Google, and I found a message on a Debian board noting that udev had started using signalfd recently. This suggested an old version might do the trick. I tried one, and it did. I really only have two things to say, after reading this... First, and this really does overshadow the second in weight, thank you for the excellently presented writeup of problem *and* solution, as more often than ever should be (less so here, but across the net as a whole), problems are mentioned, solutions are offered, and rarely does a good, clear, this worked follow. Secondly... it's been my experience, with Gentoo, that things break far more often when I allow longer delays between updating than when I keep up to date with everything, and it's held true for me on both x86 and ~x86 systems (as has the headache when I've put updates off). And.. I reiterate a part of the first... Thank you for the writeup. -- Poison [BLX] Joshua M. Murphy

If so, I would suggest the following... 1) unmerge pam. *DO NOT LOGOUT OR REBOOT* 2) put the line sys-libs/pam in /etc/portage/package.mask Create the file if it doesn't exist. 3) emerge shadow *BEFORE YOU LOG OUT OR REBOOT*. Pam is an extra-high-security option that makes sense on a public server with lots of people being able to log in. On a personal laptop it is overkill. There was a comedy album once that was called... Everything You Know Is Wrong. That describes Pam. The security settings for various services are in totally different files and locations than normal. Are you still booting from the install CD? The way you are running sshd is not how the install manual suggests to do it.

Laurent Well, if you mean always connect to internet through your remote server in terms of bypassing a firewall or silent proxy, possibly but not guaranteed (and likely against whatever agreement you have that put you in a position to be behind that firewall or proxy anyhow). To use it for that purpose, you would have to be able to, at the least, get to your remote server... which is just somewhere else on the internet itself. As for augmenting bandwidth for your local system, using the remote one... not really, no. Whatever link you use to get to the remote server is likely to be the same you're going to use to get to anywhere else on the internet, and it's that last link that tends to be the most limiting factor on speed. I have, however, used a slow link to connect to a system I had on a faster link somewhere, downloaded the files I wanted on that system, then pulled them off onto a usb drive when I was physically with that system the next time... but trying to pull from that system to where I was controlling it from would have been the same as, if not slower than, pulling those files directly from the original source. So an all around yes, but no, answer ;) -- Poison [BLX] Joshua M. Murphy

What I do fail to understand, though, is why a person would post, asking for help, disregard every bit of help given, and *both* act as though they're being forced to listen to help they didn't ask for *and* as though they're not getting any help at all. If someone gives you an answer that is wrong for the situation as you see it, it typically means one of two things... 1) you didn't give all the details needed for them to understand what you're seeing and to know WHY the answer they're giving isn't correct, which 2) you're overlooking or ignoring something that they're trying to point out in their answer and, despite what you may want to hear, they are in fact correct. Now, a-typically, it's possible you know what's wrong, what's causing it, and the solution, so you can instantly know that answers you're receiving are wrong... but in my experience, in those cases, people don't waste other people's time asking for help. -- Poison [BLX] Joshua M.

Chaos ensues. The warning appears in /etc/init.d/fsck. How do I fix this? Some option in /etc/conf.d/fsck? If you look for gentoo bug 291654 you get to a page that's difficult to read, something wonky with the xml, but it describes this problem and adds that it's fixed upstream. I'm using ext2 with the journal option, openrc and baselayout-2. My latest world update was two days ago. maxim Skipping fsck at boot, when the system's on battery, would appear to be hard coded in /etc/init.d/fsck ... and the function it uses to check is completely independent of userspace tools related to PM. The only thing it checks is the /proc tree. You can make it ignore all of that and force a check by booting with forcefsck on your kernel command line or by creating the file /forcefsck (simply using touch should suffice). You say Chaos ensues ... in what way? Further errors, failure to boot, file system corruption, or...? The problem isn't likely rooted in the fact that it doesn't run an fsck when the system's booting on battery, but rather that you have some more pressing problem that should be addressed. -- Poison [BLX] Joshua M.

I just started using it on eight Fedora servers I am administrating. Nice, now this is an improvement over my 'for $h in $HOSTS; do ssh $h yum install foo; done' approach. I feel your pain :-) We used to have the same problem adding new admins to 87 machines. Now we have a bespoke provisioner that does it all. Sorry, I just do not get 'bespoke provisioner'. Some sort of software, like clusterssh? Or a person, one admin instead of many? What do you guys think about using Gentoo for servers? At the institute I partially work we chose Fedora. There is no special reason for that - we already had some Fedora machines, the setup seemed to work, the reputation was good, so we kept it. That was okay for me, why choose many different environments and learn everything again. I mentioned Gentoo, but did not really suggest to actually use it. Maybe I should have. I'm a huge fan of Gentoo Now who would have thought of that! and all my personal machines (except the new netbook have run it for the last 5 years. But I will never install Gentoo on a production server at work. Why? Because it is too time consuming, because no two machines are set up the same, because I can't trust that other admins used the flags they should have. So updates become a case of logging into 80+ machines individually and doing emerge world by hand. Gentoo allows you to customize things to the nth degree - that is it's strength - so people WILL use this one discriminating factor. If OTOH I had a server farm of 80+ machines, all identical, I'd put Gentoo on them in a flash. But I don't have that Of our 8 machines, 7 are essentially the same and differ only in hard drive space and CPU speed. The other machine is Intel, not AMD, and needs different IDE drivers. At the moment it has a different initrd (I set up a minimal fedora install to generate it after the cloned system did not boot), the rest is - apart from some config files - identical. So I would make sure that about everything is exactly the same, well, maybe except for hostnames, udev net-persistent-rules, ssh keys... what more? The last, a little different machine is a problem though. With optimized CFLAGS, this one would have to compile all stuff again, while for the others I could use binpkgs. Updating them all with clusterssh should not be much more work than updating a single one. Well, not completely true, I would have the double work, as I would upgrade one server first to test if there are problems, and then do it for the others. Maybe I could use the special machine to test stuff, and then update all the others. If they would differ, Gentoo would of course be too much work. I already have this problem now... there is my desktop machine, my notebook running a Gentoo VM, a second desktop machine at my other home, the living-room machine of my flat share, the machine of a fried I also administrate, the server of my flat share I need to set up again... and clusterssh is no option here. My potentially ill informed thoughts on the above issues/ideas: 1) Pick one machine to host both your make.conf as well as your portage tree and distfiles, potentially splitting them into separate nfs mounts shared out for the rest of the hosts (having the portage tree itself ro on all but its owning machine forces centralization of syncing). 2) /etc/make.conf should simply be a symlink to the centrally located copy. If you must use binpackages, set march to something that will run on every machine involved, then set mcpu to whatever machine is most common if you want to get just a bit more performance here or there. If you don't mind compiling on every host, though, set portage niceness to something friendly to your users and march to native (if you plan to use distcc, this is a BAD idea, use the binpackages). 3) use a replaceable (otherwise identical to the others, and therefore able to be brought back online by just cloning it over) system for your testing and keep frequent scheduled backups of whichever system plays host to your portage tree, binpackages, and distfiles. 4) build your kernel with built in drivers for every piece of boot-time essential hardware in your systems. You'll still be on a far cleaner setup than a mass produced distro provided kernel, you'll only need to maintain one for all your systems, and you'll only have one kernel to worry about building against if you need any out-of-kernel modules as well. 5) script the changing of ssh host keys (or even redistribution of them, if you ), removal of persistent net rules, and prompting for the setting of host name and you'll have a nice, tiny, postinstall tool for the rare

I would get these SODs, black usually, but sometimes white and once green while connected to the web(don't know if that's significant). At first I thought it was the browser, so I tried firefox-3.0, firefox-3.5, opera-10. Same story, so I replaced xfce4 with fluxbox, no screen savers, no icons, widgets, just the default bar at the bottom of the screen and there was no problem for several days until this morning the desktop went totally black and wouldn't respond to mouse or keyboard. I did #tail /var/log/Xorg.0.log immediately from a spare console but there was no sign of trouble. I can get back to the start console, ctl-c and run startx again but the desktop remains black. To get back the desktop I have to reboot. Anybody guess what's happening here? Maxim From the sound of it, that'd be X itself (less likely because restarting X should resolve any direct X issues), a video driver (which doesn't, to my knowledge, get completely unloaded on closing X), or hardware issue. Since it doesn't mess with plain console, which is rendered through a different driver than X video, I'd guess that it's not hardware (I'd expect video corruption to persist through VT switching with a hardware issue). Still, could be any of the three, or something else entirely, but by the sound of it, try changing version on your video driver. -- Poison [BLX] Joshua M. Murphy
