Oui, rien de bizarre : après tout, ce sont deux dispositifs (périphériques, cartes, puces…) différents. Je ne sais pas pour la Neufbox mais une bonne partie des routeurs WiFi sont un SoC (« tout-en-un ») avec jusqu’à trois périphériques réseau intégrés : un ethernet pour la prise « entrante » (WAN), un ethernet pour le sous-réseau « sortant » (LAN) avec un hub au bout (voire un switch avec différentiation possible des différentes prises ; parfois, le WAN est d’ailleurs aussi sur le switch avec le LAN) et, de plus en plus, une WiFi (auparavant plus fréquemment en carte séparée (minipci)). Chaque périphérique ayant sa propre MAC. Oh, et puis les Freebox ont aussi plusieurs MAC rien que pour le WiFi : celles du voisinage qui ont le partage FreeWifi activé en montrent jusqu’à trois (je crois même en avoir vu quatre avec Freephonie).

Linux, Windows y reinicios
Hola, que tal ¿que puede pasar cuando tienes en un ordenador Windows (para jugar) y Debian, y lo tienes que reiniciar al menos una vez al dia para ir de un sistema operativo a otro?. Los pantallazos propios de Windows van aparte. Ya sea por reinicio desde el sistema operativo o dandole al boton de reset. ¿Puede producirse una averia?. Me da que si, pero pregunto por si acaso. ¿Puede interesar algo en especial?. Por ejemplo: si hay cierto riesgo de que se vaya la luz, interesa un SAI. Gracias.

Re: Debian right for my use?
Debian might well work for your purposes as it's relatively easy to set up and has a huge software repository; but your problem appears to be memory. If your CAD software was sluggish even when you were running Windows 7 directly, it's not going to be better when you're running Windows in a VM. I'm thinking that your VM will need access to at *least* 10 GB of RAM and all your CPU cores (both parameters are user configurable). My usual rule of thumb is that there should be at least as much virtual memory as RAM, so you may need another hard drive as well (depending on how full your current one is). In any case, if you're otherwise comfortable with Ubuntu, then there is no real need to switch, though stable releases of Debian are notoriously conservative, which may be a good thing in your case (as long as you're not looking for the latest features in the packages you install). And you may want to try to run your CAD software in Wine (in which case, you'll still need to buy some more RAM). It might work or might not, but if it does, then you won't need the VM which will make your life simpler. And you may want to see if there is a native Linux CAD system that suits your purposes, as native executables will always run better than foreign ones, no matter what OS you're running (but I can't help you there as I don't do CAD). One thing you should look at regardless is what the memory usage (real and virtual) is when you're running your CAD software; you're probably going to want at least as much physical RAM as it's using overall. Hope it helps... --| John L.

I've made and populated the 4TB drive that will take the permanent stuff that's on my current 2TB drives. I'll be switching to it today. There's one remaining question I have, which is fortunately not urgent. It's not clear what I'm going to have to do to bring the RAID online after a reboot.

Maybe not, now that you mention it.
Just /boot and nothing else. Getting the initrd and
the kernel loaded I still think is less trouble when they exist on a
simple filesystem and outside of lvm. Then use the rest of
the disk as physical volumes for lvm. For you I might suggest:
/dev/sdb1 /boot {256M}
/dev/sdb4 extended {remainder}
Why extended? I generally put my LVM partition straight in a DOS
primary partition, unless I needed more than three non-LVM partitions
for some reason.
/dev/sdb5 LVM PV {one large volume}
[...]
Is there some method that I've overlooked?
Yes. Simply add those partitions as additional PVs to the VG volume
group. If you have freed up their data then increase the size of your
volume group by using them as physical volumes. Then with more space
in your volume group you can allocate the space to your logical
volumes. There is no need to move the start of sdb5 PV down.
pvcreate /dev/sdb3
vgextend vg1 /dev/sdb3
Woops. My memory's bad sometimes. Yeah. There is no need to move stuff
inside the LVM.
You can cobble together logical partitions out of physically separated
regions of disk.
Slightly fragmented logical partitions are not even that much of a
performance penalty. I even ran a Fedora install with a /var partition
that consisted of about four separate fragments for a couple of years.
Sorry, Frank. it may not be as bad as I painted it.

Kevin O'Gorman wrote: Bob Proulx wrote: For people adding additional mdadm raid volumes later they need to do some configuration for it. This is exactly my case. I'm installing a RAID-0 for gigantic transient files. I do not anticipate using RAID for the system, partly because all bays are full. Then you will need to add the new array UUIDs to the mdadm.conf file. Since these will be non-system files for you I don't think you need them in your initrd file. The system will boot without it and will start the arrays at normal boot time based upon the mdadm.conf file. I think you can ignore the initrd part. Mdadm has two different times when it will assemble raid volumes. In reverse time order the second is at boot time by looking at /etc/mdadm/mdadm.conf file and assembling all raids configured there. That data can be created using mdadm --scan to search for physical devices and to produce the config files. Take that information and edit it as needed. Question: what is it that does this assembly at boot time? Is there a daemon that's running now that I've installed mdadm? After assembling the array there is a monitoring daemon that remains to monitor the array. mdadm --detail --scan /dev/mdadm/mdadm.conf ...edit /dev/mdadm/mdadm.conf...clean up and remove duplicate lines... I might do the same, but you give no hint what that looks like, and I am not installing a new system to find out. But you installed mdadm, right? That will set up a default /etc/mdadm/mdadm.conf file. You have installed mdadm, right? Simply add to it. Go look at your /etc/mdadm/mdadm.conf file and see what format it is in. The output of --scan would show something like this following. So I assume that is the minimum detail needed. # mdadm --examine --scan ARRAY /dev/md0 UUID=b83eb4b1:b3cd7664:92de4c59:171eb348 ARRAY /dev/md1 UUID=b2dfa6c5:670c8ba1:9c78214e:3887479c ARRAY /dev/md2 UUID=c7c71eeb:ee54031a:bee4c713:8bfe3e2c ARRAY /dev/md3 UUID=a29d3855:f5821ceb:e683083b:09bfbf48 Also if you read the man page for mdadm it gives an example in the documentation.

Both ZFS and BTRFS are unknowns to me, so I'll avoid them for now just because I'm lazy. Would either of them span multiple drives, or would I have to have a RAID anyway? MDADM RAID is simple, although it may not be easy to set up when you already have 4 drives in your system. Most MBs only allow for 6 SATA devices. However you can set up the array with a couple of simple commands. And it can be moved between machines because it doesn't depend on the hardware. Both ZFS and BTRFS allow just about everything that RAID and LVM offer plus more. BTRFS is the touted as being the next standard Linux file system. If I understand it correctly, you can upgrade ext* to btrfs in place, add new drives into the file system and remove the old ones (using the correct file system commands). Of course, nothing is 100% safe but is there a point in telling you to backup 8T of data first? MDADM RAID would allow you to copy the data to the new array before removing it from the old disks. Btrfs would allow you to revert if moving data off a drive runs into a problem. However if your current data doesn't have redundancy, a failure during the move could still mean data loss. This isn't the place for either a RAID or file system tutorial, but there are lots out there on the web.

It's not clear what I'm going to have to do to bring the RAID online after a reboot. It doesn't seem to be as simple as tweaking /etc/fstab, like it is on bare drives. I suppose I can do an assemble operation manually each time. Is there a best practice for making this automatic? If you install a system using the debian-installer then it will set everything up for you automatically. For people installing a pristine system with raid it is all automatic and nothing more needs to be done. For people adding additional mdadm raid volumes later they need to do some configuration for it. This is exactly my case. I'm installing a RAID-0 for gigantic transient files. I do not anticipate using RAID for the system, partly because all bays are full. Mdadm has two different times when it will assemble raid volumes. In reverse time order the second is at boot time by looking at /etc/mdadm/mdadm.conf file and assembling all raids configured there. That data can be created using mdadm --scan to search for physical devices and to produce the config files. Take that information and edit it as needed. Question: what is it that does this assembly at boot time? Is there a daemon that's running now that I've installed mdadm? Typically, note the append operator: mdadm --detail --scan /dev/mdadm/mdadm.conf ...edit /dev/mdadm/mdadm.conf...clean up and remove duplicate lines... The debian-installer formats the lines slightly differently than mdadm output does. I don't know if the differences are really significant. I usually edit to follow the original debian-installer format. I might do the same, but you give no hint what that looks like, and I am not installing a new system to find out. The important part is that the arrays are listed with the device and with the UUID of the array. That will instruct mdadm to assemble those arrays when mdadm is started at system boot time.

Why extended? I generally put my LVM partition straight in a DOS
primary partition, unless I needed more than three non-LVM partitions
for some reason.
I sure appreciate everyone's recommendations, even if only for learning
things I was completely ignorant of (e.g. GPT).
What I've done is rebuilt from scratch without any LVM. IMHO LVM is
[a] overkill for my simple system; and [b] lacking in a few key functions.
I might have been able to move the LVM as originally wanted - by turning
off the LVM within gparted, it seemed like it might have worked. It
was estimated that it was going to take over 6 hours, and the system
had already shown some scuff marks, so I did the rebuild.
Initially I kept the root partition (including /boot) separate from /usr.
To my disappointment systemctl still reported that the system was
'degraded', indicating that it had 'failed to start Load Kernel Modules'.
So I merged /usr into the root partition - and now systemctl indicates
that the system is 'running' without any errors. I have the impression
that boot is faster but that will remain unproven since I'm not inclined
to restore the system to its split /usr-root partition state. It seems
most likely that splitting /boot and /usr into separate partitions would
not make systemctl (and whatever init process it is hosting) any happier.
I have a 'jessie' computer at work that produces the same error message
and it seems to work just fine (local server, running 24/7) so the
message seems to be fairly insignificant (so far).

Best tools for hard drive recovery
In the midst of other activities around my hard drives, I realized one of my old backup drives has suffered some damage. Not all of the files are readable. I have more recent backups, so there's nothing catasrophic here, but before I jettison this drive I'd like to get off of it what i can.

On MS it is probably a good choice. On a Linux kernel? Maybe not. Other people have suggested VMware. Is the license for that a free(dom) license? There are other virtualization options. Xen is still very popular. I am using KVM. Bob I suggested VMware, which is no cost but not free. It's based on the problems he's reported which seem to be related to video.

Or now that I think of it, just use a Move Message action - since to a computer, a move is just a copy plus a delete. I actually do that myself, routinely; the vast majority of messages I receive are via mailing lists like this one, and every single one of them gets filtered into its own folder under Local Folders.

Dear Maintainer,
* What led up to the situation?
I had effectively 'hosed' my original Debian installation - (Which I now
remember caused me the same install
problems)- by trying to setup a 'backport' to get a later version of the 'GIMP'
program...which involved
changing my /etc/apt/sources.list file; thus I needed to do a clean install.
STARTED with Debian 7 (wheezy)...
* What exactly did you do (or not do) that was effective (or
ineffective)?
I downloaded a CD image: built: 20140426;d-i 20130613+deb7u2+b1. The md5sum
matched.
I burned the image to a CD began the install.
I tried several options both manual automatic installs in text graphical
modes. First of all
the graphics display went haywire as soon as I chose a menu entry: a black
screen space appeared
on the top 2x inches, or so, of the screen. It had several lines of tiny text
which was
virtually unreadable: undefined video ? 144 ??? space or wait 30x
seconds then the top 2x cm of
screen flashed on off with multicoloured microtype...for a VERY long
time...(~4x hours).
* What was the outcome of this action?
I gave up started the install all over AGAIN AGAIN...TRYING OUT DIFFERENT
INSTALL OPTIONS...
...TEXT BASED OPTION WORKED -(NOT!) - LED ME TO REBOOTING THE 'FINISHED'
INSTALL TO FIND
NO GUI - NO DESKTOP ENVIROMENT!!! THIS OCCURRED A COUPLE OF TIMES...{I thought
Graphical install refered
to the Installation program, NOT the final Operating System...?
Then I read all the HELP options F1 - F8 which left me MORE confused!!!
(F6 - F8 the parameters came AFTER the Hardware/Results, which seemed
BACKWARDS to me?! F7 WAS A (BAD)JOKE!)
Then I got to: Graphical Auto Install which did not work with vga=788 ; so
I remembered something
in the HELP files that said if a LAPTOP's display didn't work, to try vga=771
yea! it worked!...
...BUT AUTO INSTALL TURNED OUT TO BE MORE COMPLICATED THAN IT SOUNDED!:
Download debconf preconfiguration
file {needs URL to find it...TOO COMPLICATED FOR ME! GAVE UP TRIED AGAIN...}
I downloaded burnt Debian 7.6.0 tried 'Graphical Expert Install': YEA! NO
GRAPHICS DISPLAY PROBLEM!
YEA! IT BOOTED OK ONCE INSTALLED!!!
BTW: An aside comment: On the page where you (a 'newbie' MUST!) choose a
linux-image, how about stating
that a non-specific image allows for upgrades, whereas a specific one ties your
system to that linux-image?
+ how about stating the RELATIVE SIZES of the various partitions ESPECIALLY THE
/USR PARTITION...
...once I understood the need for SEPARATE partitions - (especially a separate
/HOME patition...)
* What outcome did you expect instead?
A more user-friendly Install system with a HELP system that newbies can
understand!

I'd actually think just the opposite. It's reasonable to expect that Debian users can comment on the negatives of Debian as its positives, and it would be irresponsible to advocate Debian (or anything else) as the ultimate solution to any and all problems. Sometimes, the appropriate answer is you probably should look elsewhere. (Speaking as someone who has both a Mac and a Windows laptop on my desk, and Debian on our production servers, at one time or another run Solaris and redhat in production, and used and experimented with lots of other distros and O/Ss over the years). As to the question at hand... I am a Draftsman working from home due to physical handicaps. I use graphic and RAM memory intensive 3D CAD software in Windows 7. My W7 OS is operating poorly and is expensive to replace. Right off the bat, My W7 OS is operating poorly and is expensive to replace seems like a poor reason to switch operating systems. Switching environments has a steep learning curve - which can easily eat into billable hours. Guaranteed that a couple of hundred bucks for a new Windows license will look cheap in hindsight. First off, you're talking software that you're using for professional purposes - your primary goal should be to make sure you can get your work done, and that your software and formats are compatible with your customers' requirements. Since you're currently using Windows based software, your first question should be what you're going to replace it with, if you move to Linux. I'd also verify that there are drivers available for your graphics board. Personally, I'd start by doing a full backup of your system, and then a clean re-install of Win7 and your CAD package. If that doesn't solve your performance problems, I'd also run some hardware diagnostics - just to make sure that your problems don't stem from, say, a failing disk drive or battery pack (if a laptop). Moving on to Linux, and Debian: If Linux is right for me; I need to replace it with a 1. Very stable, 2. With least amount of configuring and 3. User Friendly Linux OS. Debian is usually stable, but a new major version is about to be released, and one that has some significant differences in how it gets configured. If you move to Debian, I'd recommend starting with the Wheezy release (the current stable release, about to become old-stable). Wait until the new release (Jessie) is out for a while before migrating. It might also be worth noting that Debian, traditionally, has been for more knowledgeable users - it's not clear that it's the most user friendly and easy to configure breed of Linux. Ubuntu might be a better choice for a newbie to Linux (but that's based on heresay, not personal experience). A friend suggested that I replace Windows 7 with Ubuntu Trusty 14.04, which I did. It worked fine until I installed my 3D CAD software within Virtual Box. Since then Ubuntu and the software crashes often. It even reboots instead of turning the screen black when the 10 minute screen saver feature operates. This raises a whole different question: Why are you running your CAD software inside Virtual Box? From a performance standpoint, running resource-intensive software inside a VM is a bad idea. From an interface standpoint, you're more likely to run into compatibility problems with the drivers for your graphics board, if you're running inside a VM. (I wouldn't be surprised if your crashes are caused by driver problems.) And the money question: If you're running inside a VM in order to run Windows, then what's the point? You're still going to need a Windows license. All you're doing is adding is adding a couple of layers of processing overhead. More generally, running resource-intensive graphics software, along with the drivers for your graphics board, inside a VM, seems like a recipe for disaster. To summarize: 1. Try to clean up your current system first (and make sure you understand what your problem really is). 2. If you're going to move to Linux, make sure you've identified the application software you're going to run first (including stuff beyond your CAD package), and that all the drivers you need are available, 3. You might well be better off biting the bullet for software (and maybe hardware) upgrades, particularly if your current problems and/or the time involved in making changes is going to eat into billable hours.

Re: Script to email details not working in cron
Manikandan M wrote: I have written a small script to email (using ssmpt) some details, and scheduled it in crontab. The script is running as per time mentioned in the cron but ssmtp is not sending the mail. please find the details below. A couple of details to provide background to understanding cron scripts. Cron scripts like most things on the system use /bin/sh and not /bin/bash. The /bin/sh is a mostly standard shell. Not being bash means that if you use bash'isms they will not work. In the crontab PATH=/usr/bin:/bin and therefore any reference to comands from your home won't be found. Anyout output from your crontab will be mailed to your account on that system. These things can all be configured. user@host ~ $ cat bin/email-script /home/user/bin/actual-script ~/details-file ssmtp usern...@gmail.com ~/details-file echo $? ~/email-status What do you see in ~/email-status after the crontab runs? Is any output emailed to your account on the local system? Is anything stuck in the local mail queue? Run mailq to see. Do you have an MTA (such as postfix or exim4) installed on your system? mailq What is logged to /var/log/syslog when the crontask is run? less /var/log/syslog If you don't have permission for viewing syslog as yourself on your machine then add yourself to the adm group, log out, log back in again so that the adm group gets added to your running account processes, and look again. It is security protected by default but you on your own machine should be able to access it. id | grep --color adm If you are doing this for the first time and adding 'adm' then you might as well add 'staff' too. That way you will have access to your /usr/local directory tree as yourself too. Might as well do both at the same time for you on your own system. More suggestions follow in a moment. The crontab entry is as below 0 9 * * * /home/user/email-script Okay. At 9am every day run /home/user/email-script. When i execute the script manually i'm getting the email from ssmtp. but when the script is executed using cron i'm not getting the email. I checked the status of the ssmtp and the status is 127. The status of ssmtp when run manually is 127? Or when run by cron? Please can anyone suggest what might be wrong in my setup. Anytime you write a script always declare the interpreter on the first line. This is used by the system to invoke the right interpreter. In this case add #!/bin/sh to the first line of your script. That explicitly states things. Otherwise the behavior depends upon your system and various details not important to discuss here. As a general suggestion I always use $HOME instead of ~ in scripts like this as ~ is a ksh feature, now migrated to bash, now migrated to /bin/sh (as implemented by dash) but isn't a Bourne shell feature. I didn't look now to see if it is in the POSIX spec (probably is) so this is simply the guaranteed safe thing and perhaps is overly safe these days but then again I am not usually getting hit with bashism problems either. :-) Therefore your script would be changed to: #!/bin/sh /home/user/bin/actual-script $HOME/details-file ssmtp usern...@gmail.com $HOME/details-file echo $? $HOME/email-status Any output from the script will be emailed to your local account by cron. For me that is mostly convenient. For others perhaps not so convenient. For debugging it is often better to redirect everything to a log file. Sometimes it makes sense to truncate and start a new file every run. Sometimes it makes sense to keep a running log by appending to the end all of the time. It is your choice. I will append here for this example. Sometimes it is good to simply echo print specific details. #!/bin/sh exec $HOME/foo.cron.out 21 echo Beginning script /home/user/bin/actual-script $HOME/details-file echo Actual script finished. ls -ldog $HOME/details-file ssmtp usern...@gmail.com $HOME/details-file echo ssmtp exit code: $? Sometimes it is good to trace all output using -x. #!/bin/sh exec $HOME/foo.cron.out 21 set -x /home/user/bin/actual-script $HOME/details-file ls -ldog $HOME/details-file ssmtp usern...@gmail.com $HOME/details-file echo ssmtp exit code: $? I like to have statements listed in -x output using the : true operator. It does nothing but is a command and therefore the command and arguments are listed in -x tracing output. These are run but are invisible when not using -x. (Especially good for observing builtins such as case statements.) #!/bin/sh exec $HOME/foo.cron.out 21 set -x : DEBUG: Beginning actual-script /home/user/bin/actual-script $HOME/details-file ls -ldog $HOME/details-file ssmtp usern...@gmail.com $HOME/details-file : DEBUG: ssmtp exit code: $? If PATH is the issue then you can add the standard login paths to this script. (Add /usr/local/games:/usr/games too if you like.) #!/bin/sh exec $HOME/foo.cron.out 21 set -x
Re: Any advice for a user about to use LVM for the first time?
Kevin O'Gorman wrote: There's one remaining question I have, which is fortunately not urgent. It's not clear what I'm going to have to do to bring the RAID online after a reboot. It doesn't seem to be as simple as tweaking /etc/fstab, like it is on bare drives. I suppose I can do an assemble operation manually each time. Is there a best practice for making this automatic? If you install a system using the debian-installer then it will set everything up for you automatically. For people installing a pristine system with raid it is all automatic and nothing more needs to be done. For people adding additional mdadm raid volumes later they need to do some configuration for it. Mdadm has two different times when it will assemble raid volumes. In reverse time order the second is at boot time by looking at /etc/mdadm/mdadm.conf file and assembling all raids configured there. That data can be created using mdadm --scan to search for physical devices and to produce the config files. Take that information and edit it as needed. Typically, note the append operator: mdadm --detail --scan /dev/mdadm/mdadm.conf ...edit /dev/mdadm/mdadm.conf...clean up and remove duplicate lines... The debian-installer formats the lines slightly differently than mdadm output does. I don't know if the differences are really significant. I usually edit to follow the original debian-installer format. The important part is that the arrays are listed with the device and with the UUID of the array. That will instruct mdadm to assemble those arrays when mdadm is started at system boot time. However system boot time is too late for assembling the raid array holding the system itself. At early boot time in the initrd the mdadm will be invoked to assemble raid volumes. Those instructions are cached in the initrd. Therefore after changing the mdadm.conf file the initrd must be rebuilt in order to have the raid volumes assembled at early boot time before the system boots. There are many ways to rebuild the initrd. I will list out several. Choose whichever one feels good to you. update-initramfs -u That will update the initrd of the latest kernel. I assume you are booting the latest kernel. If you need to boot different kernels then use the -k option to specify the kernel version to rebuild. Or use all to rebuild all of your installed kernel's initrds. However if you are running Unstable and have many kernels left behind as lint then this may take a long time. update-initramfs -u -k all Or of course you could use the package manager. When kernels are installed the postinst script builds the initrd. You can also reconfigure the kernel package and this will rebuild the initrd too. dpkg-reconfigure linux-image-3.2.0-4-amd64 Where linux-image-3.2.0-4-amd64 is your current installed kernel. The above would be for Wheezy 7.7 Stable. Bob signature.asc Description: Digital signature
Re: Moving LVM volume?

Bob Proulx wrote:
the disk as physical volumes for lvm. For you I might suggest:
/dev/sdb1 /boot {256M}

Why extended? I generally put my LVM partition straight in a DOS
primary partition, unless I needed more than three non-LVM partitions
for some reason.
The original poster already had it as an extended partition. I was
simply editing their original listing to fit. Here is the original
poster's listing.
/dev/sdb1 / (root) {7G}
/dev/sdb2 /swap {4GB}
/dev/sdb3 /oldjunk{1G}
/dev/sdb4 extended {remainder}
/dev/sdb5 LVM{one large volume}
Therefore when I cut down that listing I simply left that part as it
was since I didn't think it mattered. They were using an unusual
format for describing the partitions and I didn't want to be too
disruptive of it thinking that it must be the way they liked it. And
since that detail wasn't significant I didn't change it.
Personally I tend to have more than four partitions. Therefore I will
almost always end up using extended partitions. And so I have gotten
into the habit of always using them. No other reason.
I do try to keep /boot as simple as possible and therefore do actively
try to always have /boot on /dev/sda1 as a simple ext2 file system
without lvm. I understand more complicated configurations work now
but they haven't always and keeping it simple for /boot has always
made things easier for me when there has been system trouble and
debugging needed.

This might be described as simulating a POP behavour in IMAP. IMAP allows retrieving a message, and IMAP allows deleting a message, so this can certainly be done. (As long as the server actually respects the delete command, rather than archiving on delete or something like that, but that would be server-specific.) If the protocol allows this, is the capability implemented in most clients? I don't know of any which do it automatically, even as a toggle-able option, but I could do it with Thunderbird message filters easily enough. Just set up a message filter on the IMAP-server Inbox folder with a Copy Message action (which copies the message to a subfolder under Local Folders), followed by a Delete Message action (which deletes the message from the source folder, which is on the IMAP server). I imagine that various other mail clients also provide sufficiently capable message-filtering or other scripting functionality.
