| 01:44.27 | OneManHateGroup | I'm having trouble accessing an old hard drive through usb. |
| 01:45.31 | OneManHateGroup | I can't see the files and I can't do anything with them. I've tried to change the permissions with chmod, but I doesn't stick |
| 01:46.48 | fsmithred | what can you see? |
| 01:47.37 | OneManHateGroup | It's an old hdd from a lappy that died... I can see the directories, but can't see anything in them |
| 01:47.59 | fsmithred | try testdisk |
| 01:48.01 | stiltr | errors in dmesg? |
| 01:48.16 | OneManHateGroup | like... the "Downloads" directory should definitely have something in it. |
| 01:51.41 | fsmithred | there's also ddrescue |
| 01:51.51 | gnarface | well, fsck it first |
| 01:52.07 | gnarface | and if it's a ntfs filesystem, make sure you have edit mode even enabled in your kernel |
| 01:52.16 | gnarface | actually do the second of those first |
| 01:53.07 | gnarface | if the laptop died but the harddrive itself was not physically damaged, it could still leave the filesystem in a bad state, but the right fsck command can sometimes fix it |
| 01:53.20 | gnarface | if the harddrive was physically damaged you're probably out of luck |
| 01:54.11 | OneManHateGroup | I'll see what fsck |
| 01:54.13 | OneManHateGroup | says |
| 01:55.04 | gnarface | smartmontools can also give you some physical diagnostic information |
| 01:58.33 | OneManHateGroup | thanks |

With rfcomm i can connect to hci0, and even blueman then shows I am connect, but that way I only get a serial port as a connection and the new audio output device does not show up in pavucontrol, so i still get no sound from it |
| 17:21.36 | gnarface | are you using pulseaudio? |
| 17:21.50 | gnarface | bluetooth audio support was removed from alsa years back |
| 17:22.14 | gnarface | there's some 3rd party forks of it still floating around the internet somewhere but i don't know exactly where |

| 17:22.51 | ejr | yes, pulseaudio. i have also loaded the bluetooth module afaik |
| 17:22.57 | gnarface | hmm, theoretically it should still work with pulseaudio |
| 17:23.15 | ejr | it did once work, but i forgot how i set it up back then, and i think it was under debian still |
| 17:23.41 | gnarface | hmm. i do have a bluetooth device here that stopped working around kernel 3.1 |
| 17:23.53 | gnarface | if it was really that long ago maybe you ran into the same issue |
| 17:24.16 | gnarface | is it only audio that doesn't work? |
| 17:24.25 | gnarface | can you transfer files with obex and stuff? |
| 17:24.46 | ejr | i don't know, i only have two audio devices with bluetooth, no smartphone or so |
| 17:26.17 | ejr | maybe bluez-alsa is the 3rd party fork you were refering to about alsa... i could try that |
| 17:26.26 | gnarface | yes, i think that's the one |
| 17:26.33 | gnarface | it used to be part of debian |
| 17:26.47 | gnarface | before pulseaudio absorbed the functionality |
| 17:26.57 | ejr | i will see if that works... |
| 17:27.04 | gnarface | it's worth a try anyway |

I think I will add a dir of files to copy into the system after squashfs mount, but before pivot root. I did this way back when 10 years ago but I do not remember how. Probably an arch unpacked on top of the mounted but not pivoted syste,m |
| 22:13.51 | _abc_ | reading /bin/live-medium-eject :: they specifically do not umount usb mass storage devices?! HUH? "need coldboot to recover" means what? |
| 22:14.27 | _abc_ | wow, sounds like 640 kB will be enough for everyone. |
| 22:15.28 | fsmithred | you can make a hookscript that will make the changes for you each time you boot |
| 22:16.01 | _abc_ | I can put the /bin/live-medium-eject on the persistence medium manually, now, edited a bit, so it will remount ro && fsck, I think |
| 22:16.07 | fsmithred | use same format as the live-config scripts for the hookscript |
| 22:16.28 | _abc_ | Or,rather, in the morning, since it's 1:15AM here and my error rate is going up a bit. |
| 22:16.47 | _abc_ | fsmithred: hm? Oh, put it in a dir so it gets exec'd? |
| 22:17.21 | fsmithred | well, you use persistence as you just described |
| 22:17.26 | _abc_ | Yes |
| 22:17.37 | fsmithred | no need for the hookscript unless you want it to work when there's no persistence |
| 22:17.58 | _abc_ | Yes. But would a hookscript be stored on the initrd? |
| 22:18.28 | _abc_ | I keep getting back to my 10 year old hack using a packed arch on the inird "dumped" on top of the squashfs+overlay mount before pivoting. |
| 22:18.34 | _abc_ | *initrd |
| 22:18.47 | _abc_ | Looks like I'll revive that some day soon, perhaps Sunday. |
| 22:19.33 | _abc_ | Windows has one thing I like, there's a set of RunOnce scripts or programs it can run once upon reboot/when needed, this could be very useful for linux at some times. Like now. |
| 22:19.55 | _abc_ | Okay, thanks for the help, will go zzz a bit in 5 mins and pick this up tomorrow or in the weekend. |
| 22:23.29 | _abc_ | fsmithred: did you check if the rebooted stick has a fsck fault after reboot? |
| 22:24.19 | fsmithred | yeah, it does |
| 22:24.41 | _abc_ | Note dosfsck reports a fault even if the media was mounted ro after that. |
| 22:24.45 | fsmithred | I also found errors inside my persistent loopfile |
| 22:24.53 | _abc_ | Oh that is not good. |
| 22:25.21 | fsmithred | just said it was not cleanly unmounted |
| 22:25.27 | _abc_ | I once tried to shut down to runlevel s then to umount the media manually, and it would not let me |
| 22:25.37 | _abc_ | That also needs addressing. |
| 22:25.38 | fsmithred | when I mount and unmount it in r2u, it's ok |
| 22:25.46 | _abc_ | mount -f -o remount.ro MUST work |
| 22:26.17 | _abc_ | I gather someone made -f not work sometimes in the kernel, or in libc, I don't remember. |
| 22:26.28 | _abc_ | Was a long time ago but now it haunts me. |
| 22:27.04 | _abc_ | Okay, more things to try out |
| 22:27.30 | _abc_ | Signing off now, going to bed a bit. Thanks and bye. |
| 22:28.02 | tuxd3v | Hello |
| 22:28.18 | tuxd3v | by accident I deleted my .bashrc file |
| 22:28.38 | fsmithred | g'night |
| 22:28.53 | fsmithred | tuxd3v, you can find a copy in /etc/skel |
| 22:29.14 | tuxd3v | well the problem is that I already had lots of my stuff there |
| 22:29.23 | tuxd3v | I still have my session open |
| 22:29.38 | tuxd3v | could it bee since bashrc is sourced |
| 22:29.42 | fsmithred | maybe you have a .bashrc~ |
| 22:29.54 | fsmithred | yes |
| 22:30.09 | fsmithred | did you have a lot of modifications in your .bashrc? |
| 22:30.27 | tuxd3v | I have some |
| 22:30.45 | tuxd3v | the problem, is that right now, I don't remember details :( |
| 22:30.51 | fsmithred | well, unless you have a backup copy, they're gone |
| 22:31.03 | fsmithred | but you probably should use the one in /etc/skel for now |
| 22:31.55 | tuxd3v | I was to delete .bash_history, has I found a security breach in one of my scripts...it echoed my passwd to stdout :S |
| 22:32.05 | tuxd3v | was --> have |
| 22:32.13 | _abc_ | fsmithred: https://www.slax.org/blog/18438-initramfs-pivot-root-solution.html related |
| 22:32.23 | tuxd3v | but I typed ~/.bashrc |
| 22:32.25 | tuxd3v | :S |
| 22:33.21 | tuxd3v | should be there any environment for my session at least that could retrieve some data bask? |
| 22:33.24 | *** part/#devuan izh_ (~denis@unaffiliated/izh/x-2009676) |
| 22:33.36 | tuxd3v | er, back |
| 22:34.15 | _abc_ | tuxd3v: normally cp /etc/skel/.bashrc ~/ does fix it |
| 22:34.29 | _abc_ | unless you edited it |
| 22:34.55 | _abc_ | tuxd3v: ? |
| 22:35.03 | tuxd3v | yes I had it edited.. |
| 22:35.42 | tuxd3v | compilers toolchains, and a lot of my stuff including personal visualization stuff |
| 22:35.46 | _abc_ | Well, in that case, copy in the above, then patch in your backed up edits. You did back it up, right? :) |
| 22:36.23 | _abc_ | Since you put so much personal stuff in it, instead of sourcing a special file with those settings, like . ~/.my_bashrc_settings |
| 22:36.54 | tuxd3v | I haven't done that.. I setet up a backup system with 12TB, but I am still configuring the remainings part of it.. |
| 22:37.15 | tuxd3v | so not yet doing backups.. |
| 22:37.17 | _abc_ | And err not backing up your $HOME is one of the other things one does not do. |
| 22:37.42 | _abc_ | Looks like starting again from scratch, then. Sorry. |
| 22:37.59 | _abc_ | In theory there are undelete file options but they do not work on modern systems and fs's. |
| 22:38.14 | tuxd3v | humm |
| 22:38.36 | tuxd3v | when you source a file...does it remains with a file descriptor open to .basjrc? |
| 22:38.40 | tuxd3v | bashrc? |
| 22:38.47 | tuxd3v | I still have my session open |
| 22:39.31 | _abc_ | No. And bash unfortunately reads and then closes it. |
| 22:39.49 | _abc_ | So no running bash instance holds an open file desc on bashrc |
| 22:40.25 | Hurgotron | the running bash process might have copied to its memory somewhere, though. |
| 22:41.05 | tuxd3v | that is a way to save what you have deleted has the file descriptors on that inode would then not be equal to zero, and so, the space would be retrievable |
| 22:41.44 | _abc_ | Hurgotron: it does not do that it interprets the file's contents |
| 22:42.00 | _abc_ | It MAY have survived in kernel buffers though |
| 22:42.23 | _abc_ | tuxd3v: you can try to open /dev/kmem with something binary reading capable and search for a string you remember from bashrc |
| 22:42.44 | _abc_ | This will be messy and you will likely need to find all the pages if it was larger than 4k |
| 22:43.08 | _abc_ | Messy because x86 is little endian and you do a binary search on unaligned strings |
| 22:45.11 | _abc_ | err eww. Looks like systemd interferes even with initrd. I see red warning lights. Something may be broken at script or kernel level there. https://www.freedesktop.org/wiki/Software/systemd/InitrdInterface/ |
| 22:46.58 | tuxd3v | well fsmithred, thanks, that will be the last resource, both bash proceses that I have none has file descriptors open to ~/.bashrc, I checked with 'lsof -nP -p processid' |
| 22:47.13 | _abc_ | I just told you they do not |
| 22:47.58 | _abc_ | tuxd3v: I am serious, open /dev/kmem and look for strings |
| 22:48.32 | _abc_ | https://www.google.com/search?q=finding+strings+in+%2Fdev%2Fkmem >> tuxd3v |
| 22:48.47 | Hurgotron | _abc_: good idea. |
| 22:50.07 | _abc_ | It's a nasty hack. Strings are not always stored in byte order in kmem |
| 22:50.23 | _abc_ | wchar_t etc |
| 22:50.24 | Hurgotron | BTW - I'd *immediately* power down a system where I deleted something without backup. As in, yanking the power cord within seconds. Then image the disk and deploy forensic tools. |
| 22:50.38 | _abc_ | O.o |
| 22:50.42 | *** part/#devuan James1138 (~james1138@184.102.74.56) |
| 22:50.53 | _abc_ | Core dump is a better idea. |
| 22:50.58 | _abc_ | Using SysRq |
| 22:51.16 | _abc_ | This will still not help much but power down is a really bad idea |
| 22:51.38 | _abc_ | You can also halt the system from SysRq and you can shut down without committing buffers etc from root cli |
| 22:52.16 | _abc_ | Going to run level s and then umounting all volumes remounted ro is another way. |
| 22:52.20 | Hurgotron | anything which prevents the system from writing to the sector with your data. Never wrecked a system losing power accidentally, so I'd take the risk. |
| 22:53.23 | _abc_ | Uhh I don't know what you see as systems, but to not pull the power on any modern boxes. Especially not industrial ones. Juniper you pull power twice in a row without waiting for it to boot and self fsck you reinstall. If it's pre 10.x junos it takes one try. |
| 22:54.28 | stiltr | You can try a set | less and see if what you need is in there. |
| 22:54.58 | _abc_ | stiltr: why would it be in a var? The content of bashrc? |
| 22:55.12 | Hurgotron | _abc_: Well desktop systems obviously. I don't usually work in the vicinity of a server so I'd have to opportunity to unplug it directly :) |
| 22:55.27 | _abc_ | Also grepping /dev/mem is urgent since all movements consume (reuse) buffer space. Whatever is in the buffer space will be overwritten eventually. |
| 22:55.51 | _abc_ | Hurgotron: unplugging a server is usually not possible without a screwdriver. |
| 22:55.56 | _abc_ | :) |
| 22:55.57 | stiltr | _abc_: Depends on what he's had in there. If it's just how his PS1 is set, it's there. Something else, maybe not. |
| 22:56.42 | stiltr | A memdump to file would preserve what's there for inspection later. |
| 22:57.17 | _abc_ | A memdump to file on mounted external volume perhaps, with mount options set to NO BUFFERING. I do not remember those by heart. |
| 22:57.35 | _abc_ | Causing a core dump and then interpreting that is the "clean" bad old way to do it. |
| 22:57.53 | stiltr | Ya, I don't know what they are either. |
| 22:58.24 | Hurgotron | _abc_: Depends on the server. the 1-4 U units at work would be easy enough to unplug if you have physical access. |
| 22:58.47 | _abc_ | The screws ensure you do not have physical access. Like cleaners, etc. |
| 22:59.00 | stiltr | I think I did something similar a long time ago trying to get back a file I deleted...eventually gave up. haha |
| 22:59.17 | stiltr | ^^^memdump, not pulling the plug |
| 22:59.28 | *** join/#devuan Xenguy_ (~Xenguy@devuan/community/Xenguy) |
| 23:00.26 | Hurgotron | _abc_: well, cages. Which are usually open when I'm working on that stuff. |
| 23:01.42 | Hurgotron | stiltr: pulling the plug once worked for me. Actually I was fast enough that the file was not even erased :) buffers not written. It's been a long time ago though. |
| 23:02.25 | stiltr | I'm sure it's doable. I've just not tried it. = ) |
| 23:03.15 | stiltr | tuxd3v: What sort of stuff was in your .bashrc file that you're wanting back? |
| 23:04.04 | _abc_ | He said env paths for compiler suites and something about visualization |
| 23:05.06 | stiltr | Oh, you're right. Forgot he'd said that. Thanks! |

| 23:41.51 | tuxd3v | sorry for the late, I was checking in a disk for something.. I don't have /dev/kmem in this machine |
| 23:41.55 | tuxd3v | :( |
| 23:42.18 | tuxd3v | Iam in the process of migrating my all disks to iscsi |
| 23:42.37 | tuxd3v | tons of disks around and uncategorized information.. |
| 23:42.45 | tuxd3v | its not usefull at the moment.. |
| 23:43.01 | tuxd3v | need to be put in palce..in 1 year it will be ok.. |
| 23:43.48 | tuxd3v | I had compiler suites, cross compiler suites, console congigs, colors, and so on.. |
| 23:44.00 | tuxd3v | er, configs |
| 23:44.48 | tuxd3v | lua environments for diferent situations also.. which is a pain in the ass to get again.. |
| 23:45.23 | tuxd3v | Any one of you have already worked with amanda backups? |
| 23:45.58 | tuxd3v | first of all, sory, I am late.. |
| 23:46.08 | tuxd3v | Thanks for your help on this! :) |
| 23:46.13 | Hurgotron | the next best thing to backups is to deploy simple versioning to your scripts, ie. cp -a script.sh script.sh-<timestamp> |
| 23:46.59 | Hurgotron | Doesn't help you now, but most of us had to learn from data loss. |
| 23:48.29 | Hurgotron | I'm mirroring my stuff to mobile disks or external servers with rsync and hardlink "deduplication" (--link-dest) |
| 23:49.09 | tuxd3v | yeah that is another solution.. |
| 23:49.19 | tuxd3v | just need to find the correct setup |
| 23:49.34 | tuxd3v | then will come the rules to aplly at each machine. |
| 23:49.35 | Hurgotron | That way I have versioned full backups without them taking up much more space than a single full backup plus incrementals. |
| 23:49.43 | stiltr | Were you using aliases or exporting variables or something totally different? |
| 23:50.19 | tuxd3v | at least exporting them I should be |
| 23:50.47 | tuxd3v | a printenv doesn't find much |
| 23:51.18 | stiltr | try set | less |
| 23:51.36 | stiltr | I'm able to find function and whatnot from my .bashrc |
| 23:51.54 | stiltr | aliases will also print current aliases |
| 23:52.19 | stiltr | (I could see the function with set, but not printenv) |
| 23:53.39 | stiltr | Though, it may be worth mentioning that isn't on a devuan box. |
| 23:55.19 | tuxd3v | I rememebr know that I had functions to save history in another shells to .bash_history also |
| 23:56.15 | gnarface | i could be wrong but i thought that was a built-in feature now that's just not on by default |
| 23:56.43 | gnarface | i don't think you need to load extra functions for it |
| 23:56.49 | gnarface | anymore, anyway |
| 23:57.43 | tuxd3v | gnarface, yes its a builtin but I needed to set functions, to control the way it behaves |
| 23:57.53 | gnarface | ah |
| 23:57.58 | tuxd3v | I just don't recall why |
| 23:58.03 | gnarface | hmm |
| 23:58.03 | tuxd3v | :S |
| 23:58.31 | gnarface | i got nothing, sorry |
| 23:59.07 | tuxd3v | be dafault history is only appended in .bash_history when you logout session |
| 23:59.15 | tuxd3v | er, default |
