penguin42ah00:24
daftykinsin fact i went to the pub before i had eaten anything00:25
daftykinsso now i need to go and make some food00:25
daftykinsbut my affliction is that i always spell pretty much perfectly even when under the influence :<00:25
penguin42haha - no pub grub?00:25
daftykinsi was too late for that really00:25
daftykinsover here, the good pub that sells good ales doesn't do food :(00:25

daftykinsand disconnecting the other drive for fun10:37
MartijnVdSpopey: The tire is still inflated ;)11:04
daftykinspopey: did you work out how to rescue all the gold bullion then? ;)11:05
MartijnVdSdaftykins: Baroque Cycle reference? :)11:06
MartijnVdSdaftykins: (with popey as Jack Shaftoe)11:06
daftykinsItalian Job ;) as he mentioned above about his pics11:06

MartijnVdSstill.. stealing gold from the south of Spain is one of the things that sets the plot of the Baroque Cycle going ;)11:07

MartijnVdSit's a good set of books/doorstops ;)11:10
daftykinshistory is a big snore for me a lot of the time, sadly11:13
daftykinsmaking some progress here at last11:16
daftykinsgot the SSD on the onboard 6Gb SATA11:16
daftykinsand found out the BIOS is ancient11:17
daftykinsscratch that, my hair pulling moment is getting closer11:20
daftykins:(11:20
brobostigonlike a homer moment, when he finds out marge is pregnant.11:22
daftykins;)11:27
daftykinsit's ok, we're back on track11:27
daftykinsjust frustrating at times when you're helping someone that isn't quite as content to change hardware things as you yourself would be11:28
SuperEngineer'\o/'11:30
penguin42which reminds me, I need to figure out how to get the case back on my nook with the serial lead11:31
SuperEngineerback in a mo - just realised I'm on 3G dongle - switching to wireless11:39
daftykinsYES \o/12:25
daftykinsdafty wins again, the lass' EFI install worked this time :)12:25
MartijnVdSyay12:26
daftykinstaking the SSD off the external Marvell controller and making it become /dev/sda instead of sdb was the ticket12:28
daftykinsplus a bit of judicial partition nuking with gparted before running ubiquity12:28
daftykins\o/12:28
daftykinsMartijnVdS: aww she got a kernel panic on reboot after an upgrade :(13:41
penguin42daftykins: What panic?13:42
daftykins"kernel panic -nott syncing attempted to kill init!"13:44
daftykinsshe typed that13:44
daftykinsi'm asking her to try booting the older kernel13:44
MartijnVdS  sounds like it can't find / /13:46
MartijnVdS?13:46
daftykinsthe liveCD installed -19 kernel worked fine13:46
daftykins-22 gave the panic, though i'm not sure if maybe it was just a one off13:47
MartijnVdSweirdness13:47
daftykinssequence of events are that she updated, then overwrote her /home with a backup from 12.0413:47
MartijnVdSmaybe the update-grub confused the system13:47
penguin42daftykins: I'm trying to remember, trying to kill init suggests it found an init but then died - odd13:48
penguin42I want this display: http://www.pcworld.com/video/26362/inside-at-t-s-network-operations-center.html13:48
MartijnVdSpenguin42: if it has its initramdisk, it has an "init"13:48
MartijnVdSpenguin42: if that can't find the proper /, it'll "die"13:48
penguin42true13:49
daftykinsah it just worked on a second try13:56
daftykinsso maybe it was a fluke13:56
daftykinsi recommended running memtest sometime to be sure the system is ok, but maybe it was just a one-off13:56
MartijnVdSweird!13:58
daftykinssure was14:00
daftykinsapparently it's saying permission denied a lot as she's overwriting all her ~/ dot files 0o14:03
=== marlinc_ is now known as marlinc
daftykinssurely not many of them are locked during use?14:08
penguin42she hasn't created a new user or has two installs and this is a different install?14:10
daftykinsthe old /home is from a 12.04 yeah - i had her chmod it to her username to move over as she wanted her config back14:13
penguin42maybe a chown -R ? On the directory not on directory/*14:14
daftykinsyeah did that14:14
daftykinsi think she installed with encryption so that might've caused the temporary panic before?14:20
daftykinscan you make the login screen the same resolution as your desktop res? for like in a VM where the native resolution isn't auto set14:32
daftykinsis there an easy way to remount /dev/shm as read+write versus read only?14:40
penguin42wth would /dev/shm be read only?!14:42
daftykinsoh, turns out her chroot didn't have /dev/shm at all14:43
penguin42nod14:43
daftykinspenguin42: apparently it's a security consideration :D14:43
daftykinsalthough basically she's decrypting her /home in the livecd to try and copy the other /home backup onto it14:43
daftykinsif that makes sense14:43
penguin42nod14:43
daftykinsi've no idea why it was proving so impossible within desktop, but that's the idea she's come up with14:43
daftykins:D14:43
penguin42only thing I can think is stuff getting confused if she has two lvm volume groups with the same name?14:44
daftykinsi got her to install with LVM off14:44
daftykinswhat'd be the right way to mount /dev/shm for the chroot? she tried: sudo mount -o bind /dev/shm /mnt/dev/shm14:45
daftykinspenguin42: kristenbb is the one with the /home troubles, not sure if you feel like helping out - you've definitely more experience than me :D15:22
kristenbbhi15:23
penguin42oh oh.....15:23
penguin42kristenbb: So what state is this thing in then?15:23
kristenbbhow can I access my encrypted home from a live cd ? I tried mounting the system (and binding proc, sys and dev) and then chrooting into it, but when I 'su kristenbb', it says: 'open: permission denied. error locking counter'. How to avoid that ?15:23
penguin42kristenbb: When you say encrypted, is that encrypted whole dist (luks/lvm) or is it ecryptfs - just encrypted home?15:24
kristenbbjust home15:24
penguin42^dist^disk15:24
penguin42ah, hmm I've only done whole disk15:24
kristenbbwell with 12.04 I was able to decrypt the home folder with just the commands above, plus ecryptfs-mount-private15:25
kristenbbbut here with 13.04 I get this error locking counter error.15:25
penguin42I've not seen that counter message before15:26
daftykinssurprises are what we love though right? :D15:29
daftykinstackling the root cause of trying to just overwrite the /home data outside of the livecd could be another plan though15:30
daftykinsbut yeah we were both stumped as to why that would do that15:30
penguin42kristenbb: did you run the ecryptfs-mount-private before running the su ?15:31
kristenbbno15:31
kristenbbthe sequence was:15:31
kristenbbthe bunch of mount commands, then chroot, then su kristen, then the error message (this is the output, but the command still returns)15:32
kristenbband then if I try ecryptfs-mount-private, it remains encrypted.15:32
penguin42ok, try the ecrypytfs-mount-private before the su15:32
mungbeanwhat a numpty i am15:33
daftykinsher chroot didn't have /dev/shm at all, which seemed to be what it wants for the decrypt15:33
mungbeanfaffed around installing kindle app on wine,15:33
mungbeanjust realisd chrome has a kindle app15:33
mungbeanno faffing required15:33
kristenbbpenguin42: are you sure it makes sense ? If I don't log into /home/kristen, how would it know which user to decrypt ? It would try to decrypt the root home, would it not ?15:33
penguin42kristenbb: Well, according to the thing on the web it looks for a .Private directory15:34
* penguin42 should at this point state I've never done this15:34
kristenbbpenguin42: if I use it from root, it says: error: encrypted private directory is not setup properly15:34
* kristenbb never have I15:35
kristenbbon 13.0415:35
kristenbbbut on 12.04 it worked fine.15:35
penguin42don't know then - I've never used ecryptfs - always stuck to luks15:36
kristenbbit seems an overkill to encrypt system files that are otherwise public. just my own files would be enough, and would be probably faster too15:36
penguin42kristenbb: Well, that depends15:37
kristenbbbesides aren't there cold boot issues with full disk encryption ?15:37
penguin42kristenbb: Since luks encrypts everything it doesn't have the same per-file penalty, but it does have per-block penalty15:37
penguin42kristenbb: It's not quite full - /boot isn't encrypted15:37
penguin42kristenbb: But it does mean things like swap and any place you might drop temporaries get encrypted15:39
kristenbbso what to do from here?  Yet another install ? I've had a lot of issues to install this one, many many hours spent in the last week, over 10 installs15:39
penguin42you've got different problems if you're doing 10 installs - go back, what's the full story15:40
kristenbbthat's a long story15:40
penguin42kristenbb: First, what are you installing on?15:40
daftykinsthe EFI troubles i solved by helping her change SATA port, penguin4215:40
penguin42oh god EFI15:41
daftykins:D15:41
daftykinsyep15:41
daftykinsSSD was on an external controller by Marvell before15:41
daftykinsi figured it was causing issues15:41
daftykinskristenbb: which made 11th time the charm, didn't it? :D15:42
penguin42 'external controller' - what do you mean?15:42
kristenbbdaftykins: yes it did15:42
daftykinsher motherboard has a Marvell chip alongside the intel PCH SATA ports15:42
daftykinsproviding two additional SATA 6Gb/sec ports15:42
penguin42kristenbb: So hang on, forgetting about the little issue of your encrypted data, what state is everything in?15:42
kristenbbpenguin42: everything is fine15:42
daftykinspenguin42: she's got a fresh EFI install on the SSD, with some data on a 3TB storage drive beside it15:43
kristenbbpenguin42: I would just like to get it working again, by copying my old home into my new computer15:43
penguin42kristenbb: ok, great - now you say you can get to the encrypted data from 12.04 ?15:43
kristenbbpenguin42: and incidentally, I'd like to be able to get to my files from a live cd if anything should go wrong15:43
kristenbbpenguin42: I don't have 12.04 anymore, but I copied my old home into another drive, yes15:43
penguin42kristenbb: OK, hang on - what version do you have currently installed?15:44
kristenbb13.0415:44
penguin42with encryption or without?15:44
kristenbbwith15:44
kristenbbwith home encryption15:44
kristenbbnot full disk15:44
penguin42ok, what I was about to suggest won't work then15:45
penguin42what is your install on, and what is your old encrypted data on?15:45
kristenbbthe old home is not encrypted15:45
kristenbbanymore15:45
penguin42so why are you trying to use ecryptfs-recover-private?15:46
kristenbbI just plan to copy it back into the new system, and securely delete it.15:46
kristenbbpenguin42: I'm just trying to copy these unencrypted files into my new home, which is encrypted15:46
penguin42but if you boot into your 13.04 doesn't automagically decrypt them - or is that the problem?15:47
kristenbbit does, but it says permission error on some files when I try to copy them, I'm assuming that's because they're in use15:48
kristenbbhence all the livecd and chrooting issues15:48
kristenbbhowever15:48
penguin42kristenbb: OK, so let me just clarify; your new 13.04 is running just fine with encrypted home directory all perms are fine, no problem ?15:48
kristenbbeven if there's another solution to copy the files into the new home without going through the chroot issues, I'd still like to know how to access my files from outside the new system, jusst in case15:49
kristenbbpenguin42: right15:49
penguin42kristenbb: OK, so the only problem is extracting the data from the old home?15:49
kristenbbpenguin42: well I did have a kernel panic, but maybe it was just random15:49
kristenbbpenguin42: no15:49
penguin42kristenbb: So what's the other problem?15:49
kristenbbpenguin42: the only problem is putting the data back to the new home.15:49
penguin42kristenbb: Right, ok15:50
kristenbbpenguin42: the extraction is done.15:50
penguin42kristenbb: as root, chown -R youruser on the old data, then as your new user copy that data15:50
kristenbbfrom the livecd?15:51
penguin42no15:51
penguin42kristenbb: From your booted, happy system15:51
penguin42kristenbb: on your booted happy system, where is your old data?15:51
kristenbbthis I had done before, and I got these permission errors15:51
kristenbbpenguin42: another disk15:51
penguin42kristenbb: OK, lets take it step at a time15:52
kristenbbpenguin42: but as I said, I'd still like to be able to access my new home from outside the new system, in case anything ever happens.15:52
kristenbband I think that if I solve this issue, I'll be able to solve the other one regarding the permission errors as well.15:53
penguin42kristenbb: well, I don't know how to do that with ecryptfs except as suggested with that webpage, and if that's not working I've not got any suggestions on that except don't use it15:53
kristenbb:(15:53
penguin42I can do it with luks, but I've never touched ecryptfs - you might have more look if you find an ecryptfs wrangler15:55
penguin42but as you might notice, I kind of treat ecryptfs like dangerous black magic15:55
daftykins>:D15:55
kristenbb:'(15:56
daftykinsi was amused at the black magic reference but yeah that's a shame15:57
daftykinsi didn't follow the above sadly as i'm on the phone15:57
penguin42kristenbb: So if you boot a 13.04 rescue disk and then try that manual ecryptfs stuff can you unlock it?15:57
kristenbbby rescue disk you mean live cd ?15:58
penguin42yeh15:59
kristenbband what do you mean by manual ?15:59
penguin42well using the ecryptfs-mount-private from the live cd16:01
kristenbbwell no I can't unlock it using this command, that's the whole point of my question.16:01
penguin42http://blog.dustinkirkland.com/2011/04/introducing-ecryptfs-recover-private.html  says to run the ecryptfs-recover-private under sudo - not as your user16:02
kristenbbmy question is: how to unlock my home folder from a live cd, seeing as I get this 'error locking counter' error when chrooting and then using 'su kristen'.16:02
penguin42kristenbb: Try following that page and don't do the su16:02
kristenbbwell then if I don't do the su, I get this other error16:03
kristenbberror: encrypted private directory is not setup correctly16:03
penguin42ok, then you need an ecryptfs expert - sorry, I don't know where to go on that16:05
kristenbbwould you happen to know one ? :)16:05
penguin42no16:06
kristenbb:(16:06
penguin42I think they all hide from people trying to recover their data16:09

daftykinskristenbb: sorry we couldn't get 100% of the way :(16:39
kristenbbit's ok i'll be waiting until someone that knows how to solve this gets here16:39
daftykins:<16:40
daftykinsi wonder if it's the encryption not helping16:40
kristenbbbut this has nothing to do with ecryptfs though, even without writing anything encryption related, i get this error with su. this is anormal16:41
daftykinsi was thinking back to the main task of just the /home overwriting really16:41
kristenbbwhat will happeen when I really need to recover my home though?16:47

penguin42hehe yes19:04
penguin42kind of just about has his Nook ST running X  - but it's far from happy :-)19:05
daftykins:O19:14
daftykinsjust for fun? :)19:14
penguin42well yeh and insanity :-)19:20
* penguin42 has an xclock on the display, but there are some...minor... problems19:21
penguin42like it not getting the touchscreen and it only updating the eink display when I give it a command19:21
daftykinspenguin42: heh i bet doing graphics would work it harder than its' used to :D19:28

mungbeanwhats it like as an ebook rdr19:53
daftykinspenguin42: were you able to contact the guy? or do you want the challenge for yourself? :D19:53
penguin42mungbean: Awful iMHO - it offers a choice of a font too large or a font too small; I'm hoping I can put something nicer on; I guess that's also doable under android19:59
penguin42daftykins: there are some patches and stuff I'm using and I've asked some people who've got a bit further on different models as well19:59
daftykinscool :)20:00
mungbeannot even 30 quid worth penguin42 ?20:03
mungbeanmaybe font is easily hackable20:03
penguin42mungbean: I guess it depends what you're reading - I was trying to read PDFs, I suspect stuff specifically formatted for it are probably OK20:04
penguin42daftykins: Nook supply the kernel source which is good; it's a bit ancient though20:08
daftykinsah that's good of them20:08
penguin42it's 2.6.29 which is a bit grim (too old for udev for example) - it's not clear to me what the parentage of the source is, and there are loads of different Android and ARM trees out there20:09
