| goddard | whats a lighter vnc client maybe terminal based? | 00:21 |
|---|---|---|
| goddard | i noticed VNC eats up a lot of resources | 00:21 |
| sarnold | 'terminal based vnc'?? | 00:21 |
| sarnold | I thought the whole point of vnc is that it's a graphical thing | 00:21 |
| sarnold | otherwise you'd just use ssh or mosh | 00:22 |
| goddard | sarnold: well something I can optimize to my liking | 00:22 |
| goddard | remmina is slow and has very little optimization options | 00:22 |
| goddard | like how can i toggle between maybe GPU accelerated versus CPU | 00:22 |
| goddard | opengl or something | 00:23 |
| goddard | some hardware does a much better job of processing images that change rapidly | 00:23 |
| CodeMouse92 | goddard: Have you already looked at the RDP Quality settings on Remmina? | 00:23 |
| goddard | its VNC | 00:23 |
| goddard | yea | 00:23 |
| goddard | changed it and no effect | 00:23 |
| goddard | it bogs to my system when running certain CUDA tasks and makes it unusable | 00:24 |
| goddard | i have had this problem with other apps as well that do CPU acceleration rather than GPU | 00:24 |
| CodeMouse92 | goddard: After you change it there, you need to apply the settings to a particular connection from its own Edit option, and Advanced -> Quality | 00:24 |
| CodeMouse92 | (That confused me for a while at first) | 00:25 |
| CodeMouse92 | And then, ofc, disconnect/reconnect | 00:25 |
| CodeMouse92 | Beyond that, I think things like VNC are *usually* heavy? | 00:25 |
| CodeMouse92 | VNC is always slower than RDP for one thing, because it's pixel-based. It's an image stream | 00:27 |
| CodeMouse92 | (And yes, those settings I mention will not apply to VNC, if you are indeed using VNC instead of RDP) | 00:28 |
| goddard | no kidding | 00:30 |
| goddard | looks like RDP is more developed | 00:31 |
| goddard | isn't RDP a windows technology | 00:31 |
| CodeMouse92 | *shrug* yes, but it works | 00:33 |
| CodeMouse92 | FreeRDP is a free implementation | 00:33 |
| CodeMouse92 | Looks like this is an open source FreeRDP server for Linux: https://github.com/neutrinolabs/xrdp | 00:35 |
| goddard | yeah thats what i just installed | 00:35 |
| CodeMouse92 | cool, gl | 00:35 |
| goddard | it connects it looks like and then the window just closes | 00:35 |
| goddard | probably some config is wrong or gotta restart the service or something? | 00:35 |
| CodeMouse92 | Probably. I know RDP does not like someone being logged in on the system when it's also hosting | 00:36 |
| CodeMouse92 | But you'll have to check the docs, I have not used xrdp before | 00:36 |
| CodeMouse92 | On Windows, RDP will actually log out the current user automatically before allowing a login over RDP | 00:37 |
| CodeMouse92 | And logged in on the local machine will kill the RDP connection | 00:37 |
| CodeMouse92 | *logging | 00:37 |

| rapid16 | How do I fix a machine that is missing 'sudo' ? | 12:34 |
| jluc | i found displaycal flatpak and could install and run it | 12:35 |
| jluc | there still is an issue since it cannot install the profile | 12:36 |

| donofrio | rapid16, missing sudo? | 12:40 |
| rapid16 | Yeah..it said sudo is not found | 12:41 |
| rapid16 | I didn't know that would be possible | 12:41 |
| donofrio | humm, perhaps login as root and apt-get install sudo -y | 12:42 |
| rapid16 | Hmm. That would be difficult...Docker container | 12:42 |
| donofrio | it is a package apt-cache search show it exists | 12:42 |
| donofrio | where did you get container? | 12:42 |
| jluc | Dispwin error says "We don't have access to the VideoLUT for clearing" | 12:43 |
| rapid16 | Digital Ocean's NGINX web server | 12:43 |
| rapid16 | From docker hub I think | 12:43 |

| Guest45 | Hey there. I'm back. I've been trying to recover a corrupted hard drive. My last steps were "sudo losetup -f -P --show path/to/file.img" and "fsck -N -V /dev/loopX" | 13:25 |
| Guest45 | So after fsck finished doing its thing. What's next? How do I explore my data? Do I have to mount file.img or /dev/loopX? | 13:26 |
| Guest45 | I don't have nearly as much GiB free on my computer to mount the entire file.img. Is there a work around or do I even need all of that space in the first place? | 13:26 |
| Guest45 | df -h /mnt returns 23G avail, however, file.img is a sparse file 184G (466G total) | 13:29 |
| leftyfb | Guest45: you don't need additional space to mount an .img file. Regardless, you need to mount the /dev/loopx's, not the img | 13:35 |
| do5rsw | leftyfb: can't yoo du mount -o loop or something similar too? | 13:36 |
| leftyfb | do5rsw: I don't see how that's relevant here | 13:37 |
| Guest45 | leftyfb How come I don't need additional space? This is puzzling | 13:37 |
| Guest45 | leftyfb Once I mount the /dev/loopX, would I be able to navigate the file system just like the rest of file system (that is with cd, ls, etc)? | 13:38 |
| leftyfb | Guest45: because the space lives in the .img, you're not taking up more space by mounting it | 13:38 |
| leftyfb | Guest45: you don't need 16G of space on your machine every time you mount a 16G flash drive | 13:38 |
| leftyfb | Guest45: yes | 13:38 |
| Guest45 | Wow, that makes sense LOL | 13:38 |
| Guest45 | I'm such an idiot hahah | 13:38 |
| do5rsw | mount -o loop <imagefile> is probably the easiest way to mount an image using /dev/loopx I guess | 13:39 |
| Guest45 | leftyfb Is there a way I should go about mounting /dev/loopX? Taking into account that this file.img was generated by gddrescue from a corrupted hard drive and then ran fsck to try and fix it | 13:40 |
| yates | i'm running remmina to connect to my lubuntu 18.04 LTS system remotely. the remote's .xsession file uses lxsession. | 13:40 |
| yates | but i don't get my shortcut keys - any way to get those to work in the remmina session? | 13:40 |
| Guest45 | do5rsw but my image is already 'mounted' as a /dev/loopX. Wouldn't that re mount it? | 13:40 |
| leftyfb | do5rsw: the .img is not a filesystem, it's an image of a drive with partitions. The whole purpose of losetup is to discover and create mount points to the individual partitions (/dev/loopx) | 13:40 |
| Guest45 | IIUC, I need to | 13:40 |
| Guest45 | Oops. I didn't mean to send that. IIUC, I need to run "sudo losetup -f -P --show path/to/file.img" first and then mount /dev/loopX | 13:41 |
| do5rsw | hm afaik /dev/loopx is no mountpoint but a device node | 13:41 |
| do5rsw | so you maybe just need to mount that device(s) | 13:42 |
| leftyfb | Guest45: yes, you're on the right track. Ignore loop mounting, it's not relevant in this case | 13:42 |
| leftyfb | do5rsw: I don't see why you're trying to suggest using tools and methods to solve a problem that isn't being presented here | 13:42 |
| do5rsw | sp I'd try to mount /dev/loopX /mountpoint | 13:42 |
| leftyfb | yes, we all know that | 13:42 |
| Guest45 | Except me, maybe | 13:44 |
| leftyfb | Guest45: you already understood you needed to mount one of the /dev/loopx's | 13:44 |
| Guest45 | So, should my mount command look like this 'mount /dev/loopX -o loop /mnt/recovery'? | 13:44 |
| leftyfb | Guest45: no, do not use loop | 13:44 |
| do5rsw | just 'mount /dev/loopX /mnt/recorvery' | 13:45 |
| leftyfb | correct | 13:45 |
| leftyfb | Guest45: loop is only used when there is no loop devices found/created for a file you're trying to mount. In this case, we used losetup to do that for us | 13:46 |
| do5rsw | correct | 13:47 |
| leftyfb | do5rsw's original suggestion was to use loop on the .img file, but that won't work when the file is multiple partitions needing multiple loop devices | 13:47 |
| do5rsw | indeed | 13:47 |
| do5rsw | this works fine with iso images and other "one-partition" images | 13:48 |
| do5rsw | but not in your case | 13:48 |
| Guest45 | I see. I'm still trying to understand what loop means in this case but to be completely honest, I'm also trying to recover my data, so I have a little list of concepts I should read on about if I don't understand it right away | 13:50 |
| Guest45 | do5rsw what would be an example of such image? Clearly not this case since it is a ext4 partitioned image, right? | 13:50 |
| TJ- | Guest45: loop is short for loopdev. "sudo losetup --find --show --partscan path/to/file" will report the loopdev created for this. Any partitions will also be mapped so you can then do things like "mount /dev/loopXp2 /mnt/fs" | 13:52 |
| leftyfb | Guest45: an iso or a .img file created from a single partition or directory, not an entire drive with multiple partitions. -o loop does the job that losetup did by automatically creating a /dev/loopx device for you if you've only got 1 filesystem to mount | 13:52 |
| TJ- | Guest45: you can determine the partition(s) with "grep 'loopX$' /proc/partitions" (where X is the loopdev number and $ is a literal $ (meaning end-of-line in regular expression) | 13:53 |
| do5rsw | however losetup seems not to throw any error if it cannot detect partitions. At least it did so on my linux laptop when I tried losetup on a raspian image | 13:57 |
| do5rsw | it thus did create and show me a loop device for it but it is not mountable | 13:57 |
| do5rsw | maye that struck you too? | 13:57 |

| do5rsw | Guest45 hm probably floppy images for examle? | 13:59 |
| TJ- | do5rsw: partitions are optional extras :) | 14:32 |
| TJ- | do5rsw: just checked; the 'lite' .img has 2 partitions shown. I did notice my earlier command was wrong though, should have been "grep loopX /proc/partitions" | 14:45 |

| Malteraate | Hi there, I'm fiddling a bit with the hardware. I have a Asus laptop (AMD CPU) FX505DV, and I'd like to be able to change the fan speed manually (even under no load, there's a spinning). There are some tutorials available but none that I saw apply to me, either using asus-fan-control or using lm-sensors and fancontrol. I therefore tried to play | 15:44 |
| Malteraate | myself and discovered the "/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5/pwm1_enable". However, I can't change the content of this file, even in sudo. Someone knows about this and could walk me through? Thank you. | 15:44 |
| oerheks | i would not fiddle with fanspeed, that should be in control of your BIOS, but if you do, be carefull; some guide https://itectec.com/ubuntu/ubuntu-how-to-control-fan-speed/ | 15:48 |
| Malteraate | oerheks: Thanks. I agree with you, though the BIOS doesn't leave me any choice in the fan configuration. I tried the link you suggest and can't have pwmconfig to work. I get the following output: ' /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed'. I saw some people suggesting to enforce lax in GRUB to alleviate this issue, I | 15:55 |
| Malteraate | tried without any success for me. That is why I started to explore by myself the "/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5/pwm1_enable" to see if I could set fan speeds by hand (just to see). Infortunately, while I can read actual fan speed in the file "/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5/fan1_input" (I can see that currently the | 15:55 |
| Malteraate | fan is at 2400 RPM), I can't set it with "echo 3000 > sudo tee /sys/devices/platform/asus-nb-wmi/hwmon/hwmon5/fan1_input" (stays still at 2400). root root is the owner of the file but permissions are r-- r-- ---. | 15:55 |
| oerheks | i feel free not to help damaging your hardware :-D | 15:58 |
| oerheks | good luck! | 15:58 |
| Malteraate | Ok :). Thanks anyway | 15:59 |
| tomreyn | Malteraate: make sure you have the latest bios, this can help improve your management options, or improve the default fan speeds. install lm-sensors and run sensors-detect to ensure all sensors are properly detected. | 15:59 |
| Malteraate | tomreyn: thank you for your reply. Indeed, I updated my BIOS to the latest version. lm-sensors runs well and the fan is correctly detected (https://pastebin.com/ntJkdn90) | 16:02 |
| tomreyn | disabling nvidia graphics may improve thermals | 16:02 |
| Malteraate | Well, turns out the fan from the graphic card doesn't run at all (from nvidia-smi, I can see that the fan is disabled. also myself, I can hear when it starts, it's on the other side of the laptop). I can therefore safely say that I want to modify the behavior of the CPU fan only. | 16:04 |
| tomreyn | also removing extra hdd's, if any, or replacing a hdd / full size ssd by an m2 may help with thermals | 16:05 |
| tomreyn | those series had overheating problems in the past https://phoronix.com/scan.php?page=news_item&px=ASUS-TUF-Ryzen-Thermal-Fix | 16:08 |
| tomreyn | (which may be why the fans are now always on/always audible) | 16:09 |
| Malteraate | Thanks for the tips. I have the Karnel 5.8 and I do have the thermal_policy_throttle able, such as the fanboost_mode as well. However even with those set to silent I have still have the CPU Fan 100% of the time. On windows, this doesn't happen and when I do light work, fans are all off. Which makes me think that there's something tweakable here. | 16:16 |
| tomreyn | The ASUS thermal policy can be configured now via /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy | 16:26 |
| lorimark | hi guys, don't mean to bother here, but i've got a new server I'm trying to plug in behind a sonic-wall dmz, and i can't seem to get traffic through to it to ssh in to the box... wondering if anyone can offer any advice - usually the sonic walls just set up fairly easily, not sure why i'm blocked here | 17:01 |
| Preppie | If you're on a dmz, you won't be able to access anything on the network | 17:02 |
| leftyfb | lorimark: can you ssh to the server from another machine on the network? | 17:02 |
| lorimark | hi leftyfb - the server is on an X3 port, my LAN is on X0, the WAN is on X1. I ran through the dmz stuff, and I can ssh from LAN to DMZ but not WAN to DMZ | 17:04 |
| lorimark | fwiw i hate sonic walls... | 17:05 |
| leftyfb | lorimark: ok, so your issue is with your network setup(sonic-wall). You'll need to seek support in that direction. Maybe try #networking | 17:05 |
| lorimark | networking!!! cool, thank you! | 17:05 |
| sixwheeledbeast | traffic from where? dmz is suppose to be separated from LAN so something seems odd. as above probably off topic. | 17:07 |
| Preppie | my understanding is he was trying to access the local network externally through the DMZ | 17:08 |
| Preppie | ssh won't work that way which is the default behavior. So, sonicwall will have to be setup to forward ssh to traffic. But yeah, this is off-topic... | 17:09 |
| sixwheeledbeast | the whole point of a dmz is it's separated from the lan. | 17:10 |
| oerheks | sudo ufw allow ssh | 17:11 |
| Preppie | ufw doesn't work like that for dmz.... | 17:11 |
| cbreak | I don't really see the point in the complexity of setting up a DMZ | 17:12 |
| Preppie | sixwheeledbeast, yes. But it's usually put in place as a method to control traffic between internet and local network. It's very useful in large organizations where if the DMZ is attacked, it won't affect the local network | 17:13 |
| cbreak | setting up simple port forwarding / allowed firewall ports seems much easier | 17:13 |
| Preppie | It's certainly annoying to setup, but it's very effective in preventing most common cyberattacks | 17:13 |
| leftyfb | feel free to continue the discussion in #networking or #ubuntu-offtopic | 17:13 |
| cbreak | Preppie: I doubt it | 17:13 |
| Preppie | simple port forwarding is ok for smaller networks | 17:13 |
| cbreak | most cyber attacks use e-mail, which is allowed, or outgoing https requests, which is also allowed :D | 17:14 |
| Preppie | cbreak, you won't believe how effective a well configured dmz is.... | 17:14 |
| leftyfb | cbreak: Preppie: feel free to continue the discussion in #networking or #ubuntu-offtopic. Lets stay on topic here with ubuntu support | 17:14 |
| Preppie | leftyfb, oh yeah, sorry mate | 17:14 |

| charco | Hi! Is there a way to setup kernel cmdline parameters in the ubuntu liveusb iso? | 17:43 |
| lotuspsychje | charco: you want to edit the ubuntu live? | 17:44 |
| charco | Yes -- I want to set the BadRam parameters so the installer doesn't use the faulty ram ranges. | 17:45 |
| leftyfb | donofrio: all official versions of ubuntu have iputils-ping installed by default | 17:45 |
| oerheks | at the point; try ubuntu without installing' you can hit F6 options | 17:45 |
| leftyfb | charco: why bother installing ubuntu on a machine with bad memory? | 17:45 |
| charco | Because it's the only machine that I have | 17:46 |
| charco | And there are few faulty address ranges (all located in the same physical page) | 17:46 |
| oerheks | oh, the F6 function does not give free parameters | 17:46 |
| oerheks | remove bad ram strip | 17:46 |
| charco | oerheks: :( | 17:46 |
| charco | it is soldered. | 17:47 |
| charco | Installing ubuntu works, I just want to make sure that the installation did not get corrupted because of the faulty ram. So I was wondering if there was any way to pass extra kernel cmdline parameters to the installer. | 17:47 |
| oerheks | not during install, after install you can edit the grubline | 17:48 |
| oerheks | add a kernel parameter memtest=4 # and it will select automaticly your bad adresses https://askubuntu.com/questions/908925/how-do-i-tell-ubuntu-not-to-use-certain-memory-addresses | 17:50 |
| oerheks | be aware; bad ram may grow... | 17:51 |
| charco | I expect to get a new computer before it grows too much :P | 17:51 |
| charco | oerheks: yeah, but my concern was during ubuntu installation, to make sure it is installed correctly | 17:51 |
| lotuspsychje | charco: there's also cubic to edit your own ubuntu iso's but will be this all worth the work? | 17:54 |
| charco | na | 17:54 |
| charco | If it's not easy to do I will just hope for the best 🤞 | 17:55 |
| PeGaSuS | hello folks. I have probably one of the stupidest questions: I already have a laptop with Windows + Xubuntu on dual boot. so the main question is: can I install a third OS but with the bootloader independent of the actual bootloader in an external HDD? so, if in another computer I plug in the external HDD and I chose to boot from it I already have the bootloader and such. I don't know if I make myself clear | 18:06 |
| PeGaSuS | basically what I want/need is an entire OS in the external drive, with its own bootloader and such, but without affecting the actual bootloader | 18:09 |
| leftyfb | PeGaSuS: yes, that is possible | 18:10 |
| PeGaSuS | any tutorial for that? I don't seem to find anything comprehensive in the matter. | 18:11 |
| leftyfb | PeGaSuS: the easiest method, physically disconnect all the other drives, plug in the usb drive, boot the installer either on another usb flash drive or cd and install | 18:12 |
| TJ- | PeGaSuS: during installation ensure you select the correct boot device - and remember by default it'll be either UEFI /or/ BIOS boot mode, but not both, so to work on other systems will need that other system to boot in the same mode | 18:13 |
| TJ- | PeGaSuS: you can manually create a dual boot mode install with some preparation before the installer | 18:14 |
| PeGaSuS | aye. but in this case I can't unplug the internal HDD. it's an eMMC card (I believe it's that the name) | 18:15 |
| PeGaSuS | and I don't want to touch the actual install | 18:15 |
| TJ- | PeGaSuS: as I said you don't need to - just ensure you select the /correct/ device where the bootloader device choice is | 18:17 |

| PeGaSuS | right. the actual bootloader is in /dev/sda so I should choose /dev/sdb (to create a portable OS) instead? | 18:19 |
| TJ- | PeGaSuS: if /dev/sdb is the device you're installing the OS to, then yes | 18:20 |
| PeGaSuS | I see. I'll give it a try in a bit. I'm just downloading the OS | 18:21 |

| leftyfb | Anyone know how to disable ipv6 within systemd-resolved? Not the whole system, that is already done and doesn't prevent systemd-resolved from attempting ipv6 lookups. Also not systemd-resolve as that's not the local caching daemon I'm referring to. | 20:10 |
| leftyfb | I also tried LinkLocalAddressing=ipv4 in networkd.conf thinking that might help but it doesn't | 20:12 |
| TJ- | leftyfb: how do you mean, disable IPv6? disable returning AAAA resource records? or disable contacting an IPv6-connected DNS server? | 20:13 |
| leftyfb | TJ-: attempting the AAAA lookups at all | 20:13 |
| TJ- | LinkLocalAddressing= is for IPv6 fe80:: or IPv4 169.254 | 20:14 |
| leftyfb | "Cache miss for example.com IN AAAA" | 20:14 |
| leftyfb | TJ-: that's only for networkd, and doesn't seem to affect systemd-resolved. I already tried it | 20:15 |
| leftyfb | TJ-: in 20 minutes there were over 2000 AAAA queries and about 20 A | 20:17 |
| leftyfb | trying to eliminate that traffic | 20:17 |
| leftyfb | as small as it is | 20:17 |
| TJ- | leftyfb: in .network files, LLMNR= is read by systemd-resolved. But that won't help what you want | 20:19 |
| leftyfb | TJ-: yeah, I'm thinking this isn't something anyone accounted for | 20:22 |
| === rhymeswithmogul is now known as signofzeta | ||
| TJ- | leftyfb: 'Cache miss...' is a 'debug' level option - are you correlating those messages to network traffic? | 20:23 |
| leftyfb | TJ-: yes | 20:24 |
| leftyfb | well, I don't have those queries shown on the server side, let me check .. maybe there isn't actually any traffic from this | 20:27 |
| leftyfb | yup, there's an AAAA and even an MX query | 20:33 |
| TJ- | leftyfb: best solutions is to drop those packets in the firewall. | 20:35 |
| leftyfb | https://pastebin.ubuntu.com/p/Mps72rndmr/ | 20:36 |
| leftyfb | TJ-: not sure how you'd go about dropping AAAA and MX queries and not A | 20:36 |
| leftyfb | either way, there's no firewall to speak of, this is a local network | 20:36 |
| TJ- | I meant on the local system | 20:36 |
| TJ- | do the queries originate from an IPv6 or IPv6 local address? | 20:37 |
| TJ- | oops, or IPv4 :) | 20:37 |
| leftyfb | ipv4 | 20:37 |
| leftyfb | ipv6 is disabled at the system level (sysctl and grub) so there's no ipv6 address on the interface in question | 20:38 |
| sarnold | leftyfb: if they're all negative responses, you could configure resolved to cache those, too; see resolved.conf(5) | 20:38 |
| leftyfb | sarnold: nope, we purposely set no-negative because we need that for other operations | 20:39 |
| sarnold | ah | 20:40 |
| sarnold | leftyfb: I couldn't find any easy examples on the dnsdist.org webpage but you could probably configure it to return servfail or nxdomain or something on AAAA records | 20:41 |
| leftyfb | oh, that's an idea. Let me see if I can dig up how to do that | 20:42 |
| TJ- | leftyfb: iptables module: https://github.com/oskar456/xt_dns | 20:48 |
| sarnold | TJ-: well that's kinda neat looking | 20:48 |
| TJ- | I thought it was in the archive | 20:49 |
| TJ- | realised it works since it's DKMS - had forgotten it was added | 20:49 |
| hoppity | Do you guys think there is a way to pass through the outside sounds through my headset internal mic to be able to hear when someon calls my name? | 20:51 |
| pasiz | hoppity: so you want to use mic as speaker+ | 20:52 |
| TJ- | hoppity: you meant through the headset speakers? | 20:52 |
| leftyfb | hoppity: I think your question is well beyond the scope of this channel. You're looking at some custom voice recognition and announcement software. Sounds pretty possible though | 20:58 |
| hoppity | voice recognition? | 20:59 |
| hoppity | No, I just want to hear what my microphone hears | 20:59 |
| hoppity | I definitely did not explaine myself correctly :p sorry | 21:00 |
| TJ- | hoppity: you can configure a monitor on the microphone and mix it to the default output (Pulseaudio) | 21:01 |
| hoppity | TJ-: thank you | 21:01 |
| pasiz | hoppity: AI like wake word? | 21:01 |
| pasiz | like hey google, but wake word is your name | 21:02 |
| hoppity | pasiz: lol what? no AI, no intelligence | 21:02 |
| hoppity | just literally hear my mic in my headset so I can hear whats happening around me | 21:02 |
| pasiz | use open back headphones | 21:02 |
| hoppity | pasiz: too late for that plus having music playing wont let you hear really | 21:02 |
| TJ- | hoppity: see https://www.scivision.dev/loopback-audio-linux-pulseaudio/ | 21:03 |
| hoppity | TJ-: thank you, you are truly the man with the answers | 21:03 |
| pasiz | so you bought insulating headphones and turn monitor on to make those like openback? | 21:04 |
| TJ- | hoppity: ahhh, that last link is the opposite of what you want | 21:04 |
| hoppity | pasiz: yes because I like to be difficult like that | 21:04 |
| hoppity | jk, I bought them for home, now I am using them at work and need to hear around me | 21:05 |
| hoppity | TJ-: lol it looked legit | 21:05 |
| TJ- | hoppity: this refers to 'line in' but where you read that, read instance 'microphone in' https://unix.stackexchange.com/questions/263274/pipe-mix-line-in-to-output-in-pulseaudio | 21:06 |
| hoppity | TJ-: thank you, seems like the loopback module is what I need | 21:06 |
| shibboleth | TJ-, ping | 21:07 |
| TJ- | hoppity: definitive info: https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#module-loopback | 21:08 |
| TJ- | shibboleth: pong | 21:08 |
| hoppity | TJ-: damn, my deepest thanks TJ, you went above and beyond the line of duty | 21:08 |
| shibboleth | TJ-, i overwrote bobs spi/bios flash with a dump from alice (mostly, made sure the serials/MAC/etc were saved) and now the bob grub issue is kinda solved | 21:09 |
| shibboleth | as in, i no longer have to unload the tpm module | 21:10 |
| pasiz | would be nice gag on your work, pop a balloon near your head, when your mic is picking far sounds and playing out quite loud to get something reasonable output ;) Some limiter would be also be reasonable to implement. | 21:10 |
| shibboleth | so, my guess was likely correct: something about the efivars | 21:10 |
| TJ- | shibboleth: ouch! | 21:10 |
| shibboleth | now, how some odd efivar makes grub > 2.02-2ubuntu8.21 bork unless you unload the tpm module for me and several other, i really don't know | 21:13 |
| shibboleth | but, having two identical systems and the issue only affecting one was handy in my case | 21:13 |
| TJ- | shibboleth: that's one reason I always buy at least 2 of everything | 21:14 |
| TJ- | swap-out on failure, comparision, A/N testing | 21:14 |
| TJ- | errr, A/B testing too | 21:15 |
| shibboleth | you weren't hit with any divine revelation while debugging/bisecting on your end? | 21:15 |
| TJ- | no, not this time :) | 21:16 |
| shibboleth | well, i guess i'm glad that "solves" the issue for me, too bad about the some hundred other people (out of umpteen millions) | 21:18 |
| shibboleth | but seriously, the issue seems to have been triggered by the diff between 8.21 and 8.23 | 21:20 |
| PeGaSuS | feedback: the installation in the external drive was successful and I just need to plug it in on another computer, boot from the external drive and I have Ubuntu running on another laptop :) | 22:00 |
| PeGaSuS | thanks for the pointers about where to install the bootloader and such | 22:01 |
| bluejaypop | I'm having a problem with certificates, just like: https://paste.ubuntu.com/p/K6W5pgTF3W/ how can it be solved? | 22:32 |
| sarnold | bluejaypop: try running this, maybe it'll give a similar error: openssl s_client -verify 2 -CApath /etc/ssl/certs/ -connect google.com.mx:443 | 22:36 |
| sarnold | bluejaypop: here's what it looks like on my focal system https://paste.ubuntu.com/p/rFhkR8qRDr/ | 22:37 |
| bluejaypop | No client certificate CA names sent | 22:37 |
| bluejaypop | SSL handshake has read 4336 bytes and written 395 bytes | 22:37 |
| bluejaypop | Verification: OK | 22:37 |
| bluejaypop | yes it works | 22:38 |
| sarnold | bluejaypop: hmm okay. I kinda expected a failure :) | 22:44 |
| bluejaypop | sarnold, worked now with https://serverfault.com/a/979014/578479 on /etc/wgetrc | 22:45 |
| sarnold | bluejaypop: so strange :/ I wonder why you had to edit it | 22:47 |
| Guest75 | Hi, using Lubuntu 20.04 LTS, when I use a VPN, my wifi disconnects randomly. But without a VPN my wifi is fine, I wonder why the VPN affects my wifi? | 22:47 |
| pasiz | it keeps constant traffic | 22:47 |
| pasiz | without it you won't notice ber | 22:47 |
| Guest75 | wym? | 22:48 |
| bluejaypop | sarnold, I did openssl version -d and I got: https://paste.ubuntu.com/p/cvgKK8yWpv/ | 22:48 |
| bluejaypop | that could be related | 22:48 |
| sarnold | bluejaypop: waaaaaat | 22:50 |
| bluejaypop | i think a repository had a different openssl package and upgrading it mesed up the OPENSSLDIR | 22:50 |
| sarnold | that 'el6' sure makes it feel like a rhel6 thing | 22:51 |
| sarnold | bluejaypop: that would certainly do it.. your dpkg -l openssl output should match one of these version numbers https://launchpad.net/ubuntu/+source/openssl | 22:52 |
| bluejaypop | yea i have this one: ii openssl 1.1.1f-1ubuntu2.4 amd64 Secure Sockets Layer toolkit - cryptographic utility | 22:53 |
| bluejaypop | i reinstalled but i get the same | 22:55 |
| sarnold | bluejaypop: okay, how about debsums -as openssl libssl1.1 ? | 22:56 |
| bluejaypop | sarnold, let me try | 22:58 |
| bluejaypop | debsums: changed file /etc/ssl/openssl.cnf (from openssl package) | 22:58 |
| bluejaypop | but i did that, i was checking the config | 22:59 |
| bluejaypop | but, nothing was changed | 22:59 |
| sarnold | hmm, I wonder where that 'el6' path came from then :/ | 22:59 |
| bluejaypop | what is shown on your installation ? | 23:00 |
| sarnold | $ openssl version -d | 23:00 |
| sarnold | OPENSSLDIR: "/usr/lib/ssl" | 23:00 |
| bluejaypop | damn | 23:00 |
| bluejaypop | you know, i have another pc and i ran the same, and I got almost the same output on OPENSSLDIR but is working okay that pc, so i dont understand now | 23:03 |
| bluejaypop | i had to do a symbolic link to that path, later i will find out what the problem is | 23:07 |
| bluejaypop | thanks sarnold for your help. | 23:07 |
| sarnold | bluejaypop: crazy. good luck :) | 23:07 |
| bluejaypop | hehe, thx | 23:07 |
