[00:00] fastputty: did you look at dmesg? and do you do TRIM? [00:00] what is trim? [00:01] basically, telling the ssd which parts of a file system are unallocated and can thus be swapped around safely. [00:01] !trim [00:01] Many Solid State Drives support TRIM, which allows the drive to do garbage collection and improves performance. Ubuntu 14.04 activates it by default. For older versions, see http://askubuntu.com/a/19480 for information on activating it. [00:04] some models can get very slow if they don't get a way to swap blocks around in the background and the file system is somewhat full. [00:08] sorry omg lost internet again, thunderstorm here [00:10] i'm also sorry, need to go to bed. gl! [00:11] some models can get very slow if they don't get a way to swap blocks around in the background and the file system is somewhat full === zbenjamin_ is now known as zbenjamin [01:34] hey guys, I had a serious problem with my computer the other day and had to basically pull the entire thing apart. Now that i've put it together, cryptsetup is refusing to allow me to boot. [01:35] https://imgur.com/vXw4Y6Y [01:35] I'm not really sure how to begin fixing this, all of the errors I find when searching are due to a kernel update. [01:38] what's a good known-to-work compact usb wifi for ubuntu? [01:38] jrgilman: do you have multiple drives in the system? did you put them back into the same [what I'm assuming is SATA] port? [01:38] i purchased a lenovo legion y7000 and the the wifi chip keeps giving me trouble to no end [01:38] edenist: I have 3 drives [01:38] I am unsure [01:39] thinking to just use a separate usb wifi [01:39] I tried putting them in the same order [01:39] should I just try juggling the cables around? [01:40] possibly. It looks like it's having trouble locating certain partions and lvm groups, with the fscrypt thrown in there, I think somethings out of order [01:40] okay === Sven_vB_ is now known as Sven_vB [01:41] I guess i'll try all possible permutations of that first [01:41] before trying to do the hard thing [01:41] what is the layout of the drives? One boot drive and some other drives mounted too? [01:41] raid? [01:41] which drives are encrypted? [01:41] 1 is encrypted [01:41] it used to be /dev/sdb [01:42] but now it's /dev/sda [01:42] i tried putting it uh [01:42] second in the SATA ports [01:42] i have enabled windows raid and i can't boot with these drives anymore [01:42] anyways sorry [01:42] the main drive has 3 partitions and is encrypted [01:42] that's the only one that matters [01:42] the other two are just data drives [01:42] nothing important on them [01:42] well [01:43] there's important stuff on them, but not important to booting [01:48] jrgilman: just focus on the main boot drive for now then. [01:48] what are some hidden gem linux games you enjoy [01:48] leave the others unplugged [01:49] it might be that drives and partitions haven't been specified with UUID, so it's getting confused at boot up [01:50] okay [01:50] I'm trying every slot now [01:54] okay [01:54] I've tried every slot for it at this point [01:55] it's refusing the mount [01:58] jrgilman:is the bootloader only present on the boot drive? Or was it accidentally [or on purpose] installed on one of the other drives too? [01:58] it should be on the main drive only [01:58] all I did was select the [01:58] "encrypt drive" option when you first install ubuntu [01:58] i mean [01:59] I don't really understand a whole lot about the bootloader, so would the prescense of those drives cause it to be installed there? [02:00] i dunno if this is helpful at all: https://imgur.com/cjP9B2i [02:00] by default it will install it on the main system drive. [02:00] I didn't play around with that [02:00] thanks. let me take a llok [02:00] *look [02:01] i apologize for the shitty lighting [02:01] all good ;-) [02:01] the worst part is i've been burned by this before but i guess i didn't learn the first time === [b0b] is now known as b0b [02:15] jrgilman: the only thing I notice is that it says root='hd1,gpt2' [02:16] it might be expecting one of the other drives to be in there [that drive would be hd0] [02:17] I'm not an expert on that matter but it's just a hypothesis, and it goes with the fact that things were fine until you pulled things apart then back together [02:17] Put another drive in, then try combinations of other locations for the boot drive [02:28] hm ok [02:33] hey is there a keylogger for ubuntu [02:35] MiguelPeru: pam_tty_audit(8) if you need a log of a terminal [02:35] x11log, logkeys, tons of those [02:36] install synaptic, for a more detailed softwarecenter [02:47] edenist: what doesn't make sense is the fact that the UUID should be the same [02:48] I'm just trying to think this through at this point [02:48] jrgilman: correct. But in the grub menu, it's referring to the HD by index [02:49] bro [02:50] OerHeks, do I need to install c++ compilers for logkeys [02:51] right [02:52] !info logkeys [02:52] Package logkeys does not exist in bionic [02:53] oh [02:54] jrgilman: when you boot with just a single drive, can you change 'hd1,gpt2' -> 'hd0,gpt2'? [02:54] under set root [02:55] !info samba [02:55] samba (source: samba): SMB/CIFS file, print, and login server for Unix. In component main, is optional. Version 2:4.7.6+dfsg~ubuntu-0ubuntu2.11 (bionic), package size 872 kB, installed size 11110 kB [02:56] will try now edenist [02:57] edenist should i change that in all locations you think [02:57] search command has a reference to it too [02:57] in the if statement [02:58] jrgilman: yes, quite right. Change it in all locations within the grub editor [02:58] same with ahci1 -> ahci0 [02:58] yep [02:59] I just realized [02:59] the other day I mounted this drive in a ubuntu vm to get some data off it using cryptsetup luksOpen etc etc [02:59] could that have changed the UUID? [03:01] that didn't work btw [03:02] jrgilman: darn :/ [03:02] no it shouldn't have changed it [03:05] hmm [03:05] so here's the thing [03:05] if grub was failing [03:05] wouldn't I not even make it to the cryptsetup screen [03:05] the part where you type the password? [03:06] the weird part about this screen is that it keeps saying "Please unlock disk sdb3_crypt" [03:06] even though there's definitely no /dev/sdb in ehre [03:07] yeah, that's the problem. related to the hd0/1 thing. It thinks it is the second drive [03:07] it's actually sda3 when no other drives are present [03:08] right [03:08] i just thought that the grub hd0/hd1 thing was seperate from the cryptsetup portion [03:08] just spit balling [03:08] this is really out of my knowledge one [03:10] zone* [03:10] i think i'm gonna attempt all 24 configurations of the three drives at this point [03:10] before going too far down the rabbit hole [03:11] jrgilman: you didn't recently upgrade ubuntu did you? [03:23] nope [03:23] not to my knowledge at least [03:23] maybe i installed some udpates [03:23] updates* [03:24] my mythbackend keeps dying, but I can't seem to see anything in the logs. It's running now, but later, it will just die. [03:24] I am running an old version [03:27] oh, I was thinking that I was on mythbuntu [03:33] Wow, I just rebooted a machine and it bootlooped like 10 times and di [03:34] died, as in froze on startup [03:35] edenist: when i try to mount the /dev/sda2 partition in a live cd [03:35] i get a structure needs cleaning error [03:35] this seems to be going somewhere [03:35] also the UUID of /dev/sda2 matches that grub menu uuid [03:37] picrel https://i.imgur.com/gVxIf6p.jpg frozen with this displayed. Assuming it's a (malformed) boot sequence output [03:38] okay i think i'm getting somewhere now [03:40] bad magic number in super-block while trying to open /dev/sda [03:40] unable to ssh into it this time. Earlier, I was able to ssh for a while between bootloops and the load was higher than 2, plus when I ran dmesg, I got things like "File /var/log/journal/3beaaebfff284d0eb9f211d1b1fec3ea/user-1000.journal corrupted or uncleanly shut down, renaming and replacing" [03:43] I'm wondering what just happened and how I could get the system back up [03:44] it's ubuntu server 18.04 (bionic) [03:45] running on a thinkpad R61 [03:45] well, it was running [03:46] it said it needed a reboot, so I ran sudo reboot and it started crashing and restarting, which was a bit terrifying. [03:48] vegii: Might be a good thing to run a file system/repair - from a liveUSB - at this time. [03:56] I'm wondering if it was HDD's fault in the first place, although that does not seem very probable. What utility should I use to fix any fs errors and what's the chance of getting it up quickly this way? It's a zoneminder box and I'm leaving in a few hours for over a week. [04:01] since it's a single hdd, is it unlikely to go quickly and smoothly? Might as well reinstall everything, but I haven't slept yet... [04:01] vegii: Only takes a few minutes to run the check. Preliminary: ' sudo fdisk -lu ' to know the targe partiton then 'sudo fsck /dev/' . [04:01] target* [04:10] thanks, will try after reseating ram, since it's behaving weirdly [04:27] ugh, the laptop itself is failing. Same artifacts with the hdd removed [04:28] assuming it's thanks to the nvidia chip from that era [04:30] Hi, I am using ubuntu 18.04, but whenever i use my bluetooth headphones i need to manually set profile to HSP/HFP when using hangouts. Is there a way to automatically switch from a2dp to HSP/HFP automatically and vice versa? [04:50] Bashing-om: Thank you. In the end, I just plugged the hdd into a second R61 I have and it's all working perfectly now. Won't be needing that laptop until I get back anyway :) [04:54] vegii: At least you know where next to start looking :( [04:54] wym? [05:03] the enclosure on that laptop is cracked, so the mobo likely experienced more flexion than needed to upset a device dating back to the introduction of RoHS and lead-free solder, so it's free to rest in peace, I'll find another machine later. [05:17] jrgilman: any luck? === kallesbar__ is now known as kallesbar [06:49] qqq [07:16] do you have ubuntu iso for non-free sources? iso complains about lwlwifi [07:16] * kreyren is helping end-user [07:16] and end-user doesnt have ethernet connection === ZaZaGX_ is now known as ZaZaGX [07:19] kreyren: What about wifi then? [07:19] kreyren: he could download the debs and manually install them using dpkg [07:20] he's using wifi, but it seems that it needs these [07:20] EriC^^, Too advanced for said user afaik assuming that he's switching from endlessos and is bad with IT in general. [07:20] debian has unofficial iso with these i was hoping you would have something alike [07:22] kreyren: the debs might be on the live iso in \pool i think [07:22] kreyren: did he have wifi on the live usb? [07:23] doubt [07:28] Hi all, I have the hdd pulled from another Ubuntu laptop. It's encrypted with LUKS. I'm struggling to mount it (yes I know the password). I've followed the instructions here: https://evilshit.wordpress.com/2012/10/29/how-to-mount-luks-encrypted-partitions-manually/ but when I get to the cryptsetup command I receive "Device /dev/sdb5/ doesn't exist or access denied. [07:29] gimmel: type "sudo parted -ls | nc termbin.com 9999" and paste [07:29] When I connect the drive it auto mounts the /boot partition. However it's the main partition I want. [07:30] EriC^^: ok, one sec [07:31] EriC^^: https://termbin.com/5x4z - note, it's the 500Gb WDC drive I'm trying to access. /dev/sdb5 [07:33] gimmel: type "sudo cryptsetup luksOpen /dev/sdb5 sdb5_crypt" [07:35] EriC^^: After entering the passphrase, I then get "Cannot use device /dev/sdb5 which is in use (already mapped or mounted). [07:36] gimmel: aha, any backstory? [07:37] EriC^^: Well, I haven't mounted anything myself, so I'm not really sure why it would be saying so. Unless it automounted something. [07:38] what's the /dev/mapper/ubuntu--vg-root one 238gb one? is it from sda5? [07:39] EriC^^: yeah, that's the live hard drive. [07:43] On a raspberry pi it is posible to set up a serial console to control the pi via serial. Is this posible to do this with a regular computer/server? [07:50] i have a system running ubuntu desktop 18.04.2 with just terrible performance [07:51] 12GB RAM, i5-4590T CPU and a SSD HD [07:51] everything is sluggish === jmcgnh_ is now known as jmcgnh [07:51] even running gnome-session-fallback [07:53] Hey, quick question. When I use Alt+Tilde to switch within an application, is there a way to make it cycle through all windows? The problem is that I have about 10 terminal windows open and I cant visually distinguish betwen them from the thumbnails so i end up tabbing to the same window multiple times As in Alt+Tilde always going to the "next" win [07:53] dow? Currently It swaps between only two windows (latest & next latest) [07:53] EriC^^: any thoughts? [07:54] Sorry that got messed up [07:54] Hey, quick question. When I use Alt+Tilde to switch within an application, is there a way to make it cycle through all windows? As in Alt+Tilde always going to the "next" window?

If I enter the password, it then mounts the /boot partition. [08:42] gimmel: dont enter it [08:43] gimmel: even if it automounts /boot that's fine [08:43] gimmel: what does 'sudo mount /dev/mapper/luks-f5f1200e-3781-48be-b10f-27e83de7d7b1 /mnt' give? === phlegethon is now known as phlgt1 [08:45] EriC^^: Sorry, I'd already disconnected the drive. I'm connecting again now. I won't enter the password. What do you want me to run after it's connected? [08:47] gimmel: type "sudo cryptsetup luksOpen /dev/sdb5 sdb5_crypt" [08:49] EriC^^: looks like it has come back as /dev/sdc5 - so I'll change both sdb5's to sdc5 ? [08:57] gimmel: yeah [08:58] hopefully, this is the right place to ask. xy problem disclaimer: ive installed ubuntu core on my raspberry pi 3b+ to try and debug a hangup during python's scipy build process under a docker image build (https://github.com/raspberrypi/linux/issues/1885). after i `snap install docker`, i failed to add myself to the docker group using `usermod` but, because group management isn't documented under snap commands, i thought the methodology changed - [08:58] am i supposed to work differently concerning groups in ubuntu core? do i manage permissions differently there? [09:01] EriC^^: ok, that just dropped to a new line. So... what next? [09:02] edd_lc, I don't know much about docker or snap but what do you mean that you failed to add yourself to the docker group? A common mistake is to forget to logout/login after adding groups [09:04] gimmel: didn't it ask for a password? [09:07] EriC^^: sorry, yes, and then dropped to a new line. [09:08] Guest_33: No, according to this https://askubuntu.com/questions/872621/how-do-you-modify-group-membership-in-ubuntu-core the group magement is done differently under ubuntu core. You can see the `usermod` attempt on his thread with the output. I'm getting the exact same thing [09:10] gimmel: alright, type 'sudo parted -ls | nc termbin.com 9999' [09:10] Guest_33: You can read a little more about it here https://bugs.launchpad.net/snappy/+bug/1495059 but I haven't found a nice doc about ubuntu core and the difference between it and the usual [distro] suspects [09:10] Launchpad bug 1495059 in Snappy "cannot add new sudo users" [Undecided,Fix released] [09:10] cant you just edit visudoer manually ? [09:11] stoiss: if you mean me, my issue is adding myself to the docker group. the "askubuntu" link right above it has my exact symptoms [09:12] oh ok [09:14] EriC^^: https://termbin.com/q3pm [09:15] gimmel: what does 'sudo mount /dev/mapper/ubuntu--vg-root /mnt' give? [09:16] EriC^^: nothing [09:16] gimmel: then "ls -l /mnt" are those the files you want? [09:18] EriC^^: Nope, they're the live hard drives files [09:20] gimmel: alright, what does "sudo vgscan | nc termbin.com 9999" give? [09:26] EriC^^: https://termbin.com/regb [09:28] Hi. Is there a way to get a LIST of WIFI connections in the area in a GUI application OUTSIDE of Gnome/Unity/KDE (in a window manager)? I know nm-connection-editor but it doesn't show a list of Access Points. [09:29] It's very frustrating to manage wifi points from cmdline. nm-c-connection-editor works fine for existing/saved connections but not for quickly selecting a new one like the topright dropdown in most Desktop Environments. [09:33] . [09:34] gimmel: seems like it's the old-hdd [09:34] Industrial: how have you been managing your wifi connection from a terminal so far? [09:35] EriC^^: right, so how do I mount that? [09:35] Industrial: and if you're ok with the network manager applet (top corner menu), why not use this? [09:36] gimmel: try "sudo vgchange -a n old-hdd" [09:37] EriC^^: 0 logical volume(s) in volume group "old-hdd" now active [09:37] gimmel: hmm no idea [09:40] EriC^^: hmm, thanks for the help so far. I find it odd that it's so hard to mount a Ubuntu drive in Ubuntu :/ [09:40] gimmel: it usually isn't [09:41] EriC^^: Should I unplug, reboot and try again? [09:43] gimmel: try "sudo vgdisplay old-hdd" [09:46] EriC^^: https://pastebin.com/MyXzzGsY [09:50] EriC^^: so, it's the right group name [09:50] gimmel: what about "sudo vgchange -ay old-hdd" [09:50] gimmel: yeah [09:50] that command is supposed to activate all the volumes [09:51] EriC^^: 2 logical volume(s) in volume group "old-hdd" now active [09:51] gimmel: nice [09:51] (it also made the drive buzz on my lap :P ) [09:51] gimmel: try "sudo lvdisplay | nc termbin.com 9999" [09:52] EriC^^: https://termbin.com/iq1x [09:53] gimmel: try "sudo umount /mnt && sudo mount /dev/old-hdd/root /mnt" [09:53] I've followed different guides for switching to vanilla gnome, but I don't get the Gnome on Xorg option on the login screen. Specifically this guide: https://www.freeyourdesktop.com/2018/09/installing-vanilla-gnome-in-ubuntu-18-04-and-start-with-a-clean-slate/ [09:53] EriC^^: nailed it. Thanks so much!!! [09:53] gimmel: great! no problem [09:54] EriC^^: Care to explain what that was all about? [09:54] gimmel: no idea tbh, it usually activates the lvm stuff after decrypting, for some reason it wasn't [09:55] EriC^^: originally the group name was the same as the live drive. Could that have borked it? [09:55] EriC^^: in my troubleshooting, I found the idea of renaming the group to old-hdd to differentiate [09:55] gimmel: maybe, i doubt though, seems it's taken to old-hdd now [09:56] EriC^^: *hands in the air* who knows. Thanks again though.

I usually set microphone mute and output-devices at some value. Has anyoan had this issue, or, if it's an option or ... something, does anyone know how to disable it? [11:47] cyberalex4life: Do you mean that each time you login your microphone gets on and output devices get muted? [11:51] EoflaOE, yeah.... I read about some malware gnome-shell-extension that does that, but didn't find anything [11:51] cyberalex4life, so do you want devices muted at login or ...? [11:53] BluesKaj, no, I want output-devices, headphones, whatever to keep their volume from when I logged out, and microphone also to do so. [11:53] whatever I do, on login I get microphone on and sound muted [11:54] it doesn't preserve state [11:56] cyberalex4life, open alsamixer in the console, check the automute control on the far right and use the down arrow key to disable it [11:57] use the < > keys to navigate [12:02] BluesKaj, thanks BluesKaj [12:03] cyberalex4life: Now reboot and see if it works [12:04] cyberalex4life, to solidify your choices, run, sudo alsactl store, at the prompt [12:05] BluesKaj, Oh I think I'll reboot later, I have some work to do, but yeah it was enabled [12:06] cyberalex4life, yes, it's disabled by default so you don't blast your speakers === morphis5 is now known as morphis [12:13] hello, could someone tell me, why does installing ubuntu server with 'docker' checkbox checked in it's installer results into a VM with a working docker, but no docker group and no package in apt grepped by 'docker' [12:13] Hello I'm using a minimal install of Ubuntu so the command line only, how would I go about changing the resolution as Ubuntu is running on my monitors native resolution which causes graphical errors, I know when the resolution is lowered these problems disappear [12:14] pomeha: check snap [12:14] jtjh95: You mean CLI only? Or Ubuntu Server? [12:14] EoflaOE Command line only [12:14] jtjh95: are you using xorg? [12:14] EoflaOE: Ubuntu server is CLI-only by default [12:15] leftyfb: I know, because I have seen it. [12:15] How do I check? For xorg [12:15] jtjh95: if you're command-line only, xorg isn't relevant [12:15] jtjh95: do you mean the resolution of the tty? or the graphical desktop? [12:16] ah nevermind [12:16] leftyfb: oh my.. [12:16] resolution of tty I have no graphical desktop [12:16] leftyfb: thanks [12:16] jtjh95: i think you can set that up from grub [12:16] what's `core` snap?

[12:24] No Ubuntu before 19.04 had that and other OSes (Openindiana and Windows 10) work just fine with this audio [12:26] It is ASUS P5W DH Deluxe motherboard with ICH7 south bridge, NM10/ICH7 Family High Definition Audio Controller [8086:27D8] [12:26] as the audio device [12:26] I reported this few weeks after 19.04 came out. Still here . [12:27] nikolam: okay. [12:27] it also clicks loudly when audio stream stops playing [12:30] And now clicks by itself from time to time, like initializing audio [12:36] It is annoying to the point I couldn'ts sleep with speakers on , like before 19.04 [12:39] nikolam, i suggest you to test a previous kernel ,or better, a 19.04 livecd [12:41] I am just coming from previous kernel (18.10 xubuntu) and there it worked fine as on any other OS. I also just upgraded to 19.04 right now . But I suppose you want to make sure if the bug was acquired after 19.04 release? [12:41] So testing 19.04 live cd will make sense, since it is older then current 19.04. [12:43] ok ioria [12:43] is there a reliable way to turn off the monitor of say a laptop with ubuntu ( xfce) instantly and then turn back in when you press a key ? it seems most things ive found are for way back versions of ubuntu [12:45] stoiss: xset s activate if you're using xorg [12:46] EriC^^, will that turn off the monitor if i bind that to a keypress ? [12:47] stoiss: yeah [12:47] EriC^^, and it will turn back on when i hit another key ? [12:47] yeah [12:51] nice. thanks [12:51] no problem [12:52] what could be the reason that I still need to enter my sudo password in ubuntu even after adding NOPASSWD: ALL to visudo? [12:53] EriC^^, well it flash my screen but doesnt turn it off or anything. it seems like it does for a fraction of a second. [12:54] stoiss: odd, it makes it black for me til i press something [12:54] just xset s activate [12:54] ejr: Pastebin the output of sudoers file. [12:54] my screen flash for what seems like 1/10th or so [12:54] stoiss: try in a terminal "xset s activate" [12:54] EriC^^, thats what im doing. in a terminal [12:54] maybe it's picking up the key release from your keybind [12:55] oh [12:55] i didnt use any keybind. just paste it in a terminal and run it [12:55] hm it does work with ALT F2 and paste in that command [12:56] EoflaOE: https://termbin.com/enup [12:57] i tried binding it and it does seem like the release is what causes it to break it [12:58] stoiss: you could possibly put it in a script that runs "sleep 1 && xset s activate" [12:58] that would give you enough time to release the keys before it runs [12:58] yes. wouldnt that work with a keybind as well ? [12:59] yeah that's the point [12:59] ejr: If the group lines are after user lines, it overrides the settings, so that's why it's still asking for a password. You can move all the group lines above the first user line, so the settings don't get overridden. After doing it, is sudo still asking for password? [13:03] will check, thanks! [13:04] ejr: You are welcome. Tell me if sudo asks for password again. [13:05] EriC^^, i made a bash script then used keybinding to activate it. It does work but it seems to deactivate with mouse movement. Is there a way to deactivate mouse or only respond to keypress ? [13:07] stoiss: i dont think so [13:09] hm well thanks. ill look into how at least pause the mouse or something [13:10] stoiss: it doesnt work with xinput to disable the mouse, i just tried fwiw [13:10] allright. thanks [13:11] stoiss: seems to work with xset dpms though [13:11] 1 sec [13:11] stoiss: yeah [13:11] stoiss: disabling the mouse using xinput --set-prop "Device Enabled" 0 [13:11] then xset dpms force off [13:12] allright thanks. ill take a look [13:12] works, but then you'd need i guess to make 2 keybinds, 1 that does those and the other that you press to wake it up and reenable the mouse [13:22] yeah. ill figure out how to work it. [13:22] thanks for the help [13:23] stoiss: alright, no problem [13:34] hello! I'm trying to solve a networking problem: I've just installed an openvpn server with docker and it works. The client can connect to LAN hosts but every port on the openvpn server seems filtered but If I disable ufw it works. I just need to add the correct rule, but I need help in finding out which one [13:34] track down the ports needed and open them? [13:35] compdoc: problem is that I can't find the correct it of the openvpn client [13:36] giaco, so you installed a firewall on the docker host? [13:37] The vpn clients are getting an ip in subnet 192.168.255.0 inside the docker container, but "ufw allow flow 192.168.255.0/24" don't work [13:37] I use KVM and virt-manager, so dont know much about docker [13:37] compdoc: yes. Docker container works in network_mode: host, but the tun0 device is inside the docker container and not on host [13:38] what is the ip address ranger of the lan the guests connect to? [13:38] range [13:39] 192.168.255.0/24, so the client get something like 192.168.255.1. It would be ok to me to allow the whole subnet, but it seems not the point [13:39] there is normally no firewall installed on ubuntu, so the problems are releated to docker? [13:39] compdoc: ufw is installed by default, isn't it? Is it considered a firewall? [13:39] no, but you caninstalled ufw and create rules [13:40] *can install [13:42] compdoc: ok, so I did install ufw in the past to limit ssh connection only from some source ips, and it works. But that seems not the point: docker container iptables rules comes before the ufw ones, so every port used by docker and exposed through docker commands is by default open for every source [13:42] compdoc: I think ufw is installed by default, just not enabled by default [13:43] that's why I don't need to allow openvpn port to make the openvpn container work (see here for details https://www.techrepublic.com/article/how-to-fix-the-docker-and-ufw-security-flaw/) [13:45] problem here is that once the vpn clients connects to the docker container running in host mode, it won't connect to local (docker host) services due to uwf. I could just do "ufw allow XXX" and it would work, but I want to allow the service for vpn clients and not the whole internet [13:45] pragmaticenigma, I think iptables is installed by default but has no rules, and you can install the ufw gui to set rules. [13:45] but either way, youre right, its not used by default [13:46] so question is: what is the correct rule to "allow all ports for connected vpn clients only"? [13:47] as I said "ufw allow from 192.168.255.0/24" doesn't work. Apparently that is the ip the client gets inside the docker container [13:50] giaco, 192.168.255.0/24 is the local range, but many firewalls I use require allowig the range the client is using, so that would be a problem if random clients connect and you dont know their ranges beforehand [13:50] wait, I think I've just solved === NickG365_ is now known as NickG365 [13:50] compdoc: no, ufw let's you use subnets [13:50] thats not what I mean [13:51] The solution of my problem is not allowing the vpn clients ip, but the vpn server container ip [13:52] makes sense [13:52] so basically ufw allow form 172.22.0.something === Gilfoyle- is now known as Church- [15:23] if I generate a .crt and .pem from a pfx certificate where should I put the pem ? I know that the cert must be placed in /usr/local/share/ca-certificates/ [15:35] Leaving #ubuntu by alien64's Request [15:38] INSANU: what is the pfx file said to be used for? [15:44] Ubuntu 18.04 in an LXC: Apache24 just doens't run. I get an error: /usr/sbin/apache2ctl: 99: ulimit: error setting limit (Operation not permitted) [15:44] However, setting the limits in /etc/security/limits.conf of the host and the guest doesn't make a difference [15:45] Why would this be so? Apache24 is pretty ubiquous... [15:52] lifeboy: looks like your lxc guest has stricter limits set than apache httpd requests: lxc config show | grep ^limits [16:01] How do I export the shiftfs patch? [16:03] i guess this is just curlftpfs bugging out? http://paste.debian.net/plain/1093733 [16:03] tomreyn: my lxc run in proxmox, so I don't have the lxc command. There is a "pct config ", but it doens't show any limits. I'll ask over at proxmox [16:04] it's mounted as curlftpfs#ftp://dedibackup-dc3.online.net/ /m2 fuse rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other 0 0 [16:05] lifeboy: lxc command is in lxd, not in lxc [16:13] fling: proxmox doesn't run lxd yet, it still lxc [16:13] lifeboy: this explains why you don't have an lxc command [16:14] hey, when I run fsck, should I get more output other than just "fsck from util-linux 2.31.1"? [16:15] I'm taking it up with the Proxmox team if I still can't get it to work [16:15]
