[00:39] recommendations on software (free/opensource/linux) for monitoring security cameras? supporting PZT and two way audio? [00:42] hanasaki: no such thing [00:43] SpiritHorse: thanks. so what would you recommend for controlling camera over IP ? [00:43] hanasaki: what I do is pull the rtmp feed from the camera with whatever (in my case ffmpeg)... for PTZ I use ONVIF [00:44] thakns. SpiritHorse what software packages do you use for the onvif? anything that has a web interface? [00:44] zoneminder is what is most popular, but will lack audio support and it's a bit overweight [00:46] I use a python module to do onvif, not aware of a web interface frontend but totally possible it exists [00:50] thanks [00:50] sounds like there is no decent linux NVR and security software . SpiritHorse , correct? [00:51] most people are going with zoneminder but it lacks the audio support you're looking for [00:51] but in general, yeah, the options are pretty bad [00:55] how do I get help installing 19.10? could trying to install this release corrupt my windows partition, or make me unable to boot into it? [00:56] is the current LTS simply not compatible with AMD ryzen 7? [00:57] sappheiros: im using 19.04 on my ryzen 3700u. works just fine. [00:57] how do i find whether my ryzen7 is 3700u? [00:57] it's "vega graphics" [00:57] laptop? [00:57] yes [00:58] Screenfetch will show you what it is. [00:58] or just check the specs from when you bought your laptop. [00:59] i only have win10 right now [00:59] i do have 3700u [00:59] but 19.04 wouldn't boot on my laptop: just a black screen [00:59] device manager? [01:00] ?? [01:00] did you install a bootmanager? [01:00] i was using the liveUSB [01:02] Do you get to choose os during boot? [01:04] Or did you simply overwrite your windows partition when you installed ubuntu? [01:05] i can choose between OS, yes. [01:05] however, checking disc for defects results in that same black screen [01:06] So you can boot into ubuntu but not into windows anymore? [01:11] flog, no, this is the problem: https://askubuntu.com/questions/1162746/why-wont-my-hp-envy-x360-laptop-with-ryzen-7-3700u-boot-ubuntu-live-cd [01:12] i guess i will give up trying to use ubuntu until this laptop is supported [01:12] i don't have the time to learn how to do all this [01:13] maybe 19.10 will work if it has the newer kernel, once it's released next month [01:14] Cant say for the hp envy.

[13:14] glitchd: Sorry... got two conversations going [13:15] glitchd: Follow the instructions... if you're already in Ubuntu, you should be able to restore by running the update-grub command [13:15] pragmaticenigma, windows is installed on sdd and linux is installed on sdc [13:16] pragmaticenigma, i tried that already, it didnt work. when i select the windows item from grub it just errors out and sends me back to grub.

That is why you are seeing the Radeon driver being loaded instead of the amdgpu: https://help.ubuntu.com/community/AMDGPU-Driver [13:20] glitchd: for you, is the update grub script not able to find your windows installation? It shouldn't matter if it is on a different drive, the tool usually scans for all bootable OS's [13:21] pragmaticenigma, it does indeed find it and even put a windows 10 listing in the grub menu, but when i select it, it give an error that the partition does no exist [13:21] Ok, but i read it do provide basic support for hd8550 in a post [13:22] hay207: The page I linked is the source of truth, what is written there is what is officially supported [13:23] glitchd: Are you working with a mixed UEFI and legacy boot configuration?

[13:25] no [13:25] pragmaticenigma, so i know i need to point grub to the efi partition of the windows install, but i cant figure out the number i need to use [13:26] hay207, no. [13:26] How you got a screenshot of bootscreen? [13:26] hay207, grub-emu and a screenshot [13:26] pragmaticenigma: any insight ? [13:27] afidegnum: Actual EFI fixing isn't something I'm very familiar with. I know there are a couple other volunteers here (usually online in a couple hours) that are better suited for helping on this issue [13:28] pragmaticenigma, not a problem, i can come back later. im still able to boot into windows if i change the boot order so it not a life or death situation. [13:28] glitchd: Does Windows have bitlocker running? [13:29] pragmaticenigma, honestly i have no idea. im in linux atm so i cant even check [13:29] pragmaticenigma, but it is a super fresh install, i just built this system in the last week or so. [13:29] glitchd: Bitlocker would be something you had to have enabled when you installed/configured your windows insatallation [13:30] pragmaticenigma, well i dont remember specifically enabling that feature, so my guess would be no [13:32] pragmaticenigma, ive gotta run man, thx for the intended help. [13:58] So I originally install Ubuntu with partitional file system since it was my 2nd install I did not want to complicate things. Now my media server have been expanded accross several hds and is just to spread out to find anything. I know I have to reinstall to use lvm to cure then problem. Do I also need to off load the data from all my hard drives [13:58] and format them again. Or will that not be necessary [14:01] yeah you can't do in-place swaps [14:02] if you can offload -one- [14:02] you can lvm that one, move data back onto it, offload the next one, etc. [14:02] Oh my ok that was my next question [14:03] Jesus this is going to be a long day that no one can watch TV on. [14:04] There is not a more elegant solution I'm not thinking of correct lol. ( Prays for miracle) [14:04] well, *elegant* sounds like buying a new pile of six hard drives and installing zfs and moving everything over :D [14:05] Killerherts, there are way *less* elegant solutions that might limit downtime [14:07] Lol sarnold that will be a hard sell to the wife. Ok well looks like I'm backing up some tbs today to get this converstion going [14:08] in truth you could probably just do eg two 8tb or 10tb drives, I hear you can get good ones in a usb enclosure for something like $180.. and 10tb would fit most people's media collectoins [14:09] buying more drives than that are just to put off having a full pool for a few years [14:10] This is ultimately where it's all going I need an excuse to learn how to set up lvm so I can say I know a little bit about it [14:11] Seems like you gotta break a few things in Linux before you can really understand it [14:13] definitely that's a good inccentive to learn how to fix things :) thogh hopefully there are easier ways [14:15] I'll keep poking around your zfs input is now my new Google rabbit hole [14:15] Thanks for the help [14:15] Killerherts: https://pthree.org/2012/12/04/zfs-administration-part-i-vdevs/ my favourite series of blog posts :) [14:17] Nice thanks well looks like I got some reading to handle thanks [14:18] :D === coffeeguy is now known as zenguy [14:39] Hi everyone, there's a package update for wireshark which seems to fix CVE-2019-12295 but the changelog includes a point saying "Non-maintainer upload". With a security update I'm sort of wary to apply it from a non-maintainer without understanding at least part of the background. Is this a normal procedure? [14:45] bogn, hi, you are referring to https://usn.ubuntu.com/4133-1/ ? [14:45] CVE-2019-12295 and CVE-2019-13619 [14:45] Yes [14:50] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=929446#17 [14:50] Debian bug 929446 in src:wireshark "wireshark: CVE-2019-12295" [Grave,Fixed] [14:51] bogn, i think you can trust these archives, they come from debian ? https://packages.ubuntu.com/source/bionic-updates/wireshark [14:51] git [14:52] debian has its own repos seperate from ubuntu's OerHeks [14:54] tonyt, the original maintainer is Balint Reczey ( debian) [14:54] k [14:54] that is where we got the sources from, to be more precise [14:54] balint maintains wireshark for both debian and ubuntu. he's a canonical employee. [14:56] bogn: the ubuntu security team sponsors updates prepared by community members. we work with our community members to ensure the fixes come from upstream authors [14:57] https://wiki.ubuntu.com/SecurityTeam/UpdateProcedures gives some guidelines [15:10] OK, I was just confused by the wording Non-maintainer Upload in the context of a security update [15:12] bogn, we appreciate your alertness [15:12] So I took away that the the non-maintainer is in this case a debian maintainer instead of an ubuntu maintainer. I think I can trust this enough. [15:12] Thanks for the infos. [15:13] have fun! === SimonNL is now known as SimonNL_Afk [15:36] Hi, I have an extention that shows me the cpu usage the power govenor etc, and this thing almost always show something like" system overload, CPU throttled (some large int), IRQImbalance detected" [15:37] and often times it shows the cpu max at like 1.8. when I believe it shouled be in the 3 range. can someone help me understand what this means? [15:41] cpu throttled sounds like an overheating problem [15:42] low frequency also indicates overheat [15:42] but low frequency could be normal if system is idling [15:43] no, it's not idle, it's crankin [15:43] iffraff: You should also compare the results of the extension against better known CLI tools that perform the same tasks. Extensions sometimes are written with a focus on the author's own system and don't always leverage the correct information for other system configurations. [15:44] pragmaticenigma: can you suggest a cli tool that is well respected? [15:44] iffraff, I'd run `watch sensors` and see if temps are staying below 70C [15:45] if not, definitely a thermal problem [15:47] so, here's one of the cores, i definitely saw them hitting like 72 but mostly mid to high 50's [15:47] iffraff, might need `sudo apt install lm-sensors` for the `sensors` command to work [15:47] Core 0: +60.0°C (high = +100.0°C, crit = +100.0°C) [15:47] 60 is okay. it won't throttle because of that [15:48] iffraff: I tend to use nmon for a lot of my system monitoring [15:48] I guess there are two issues, the cpu throttling, which at this moment is not the reading, and the irqimbalance detected [15:49] do y'all know what the irqimbalance thing is? [15:49] irqbalance attempts to spread hardware IRQs across cores [15:49] so they aren't all going to the same CPU [15:50] so, an imbalance sounds kind of bad === Exterminador- is now known as Exterminador [15:50] if it doesn't occur often, it is probably fine [15:50] Hi there! How do i enable /tmp access to a snap-packaged application? [15:50] it's pretty much always there [15:50] iffraff, repeatedly? [15:51] once is no problem at all, it's just reporting that it is doing it [15:51] doug16k: everytime I open this extension it says that. when the cpu is being throttled it's all in red but the rest of the time it's in yello [15:51] does nmon report irqbalance? [15:54] iffraff: no... but it can report cpu throttling, I use it to see where system bottlenecks are... i.e. CPU graphs show large amounts of Waits, because the Disk I/O is still clearing [15:57] is 12 - 17 a large amount of waits? [15:59] what is the best tool for making freecell game for ubuntu? [16:03] For some reason when I adjust volume, it doesn't effect the voloume of speakers plugged in via headphone jack [16:04] it only affects the current output afaik [16:05] Well, when they are plugged in, they should be current output [16:05] you hear sound from them? [16:06] Yes, but volume control doesn't work [16:08] hmm for me that works, i use https://extensions.gnome.org/extension/751/audio-output-switcher/ for switching between outputs (e.g. HDMI, Headphone etc) [16:08] maybe you can check with alsamixer? not sure [16:08] doug16k: or pragmaticenigma so switching gears to the cpu throttling, I'm doing some moible development ( for android ) and via sys mon, I see all 8 cpu's maxed out. if this is then throttling them down to half speed I'm kind of screwed, what can I do about this? [16:09] Think I found it....it was set to send to HDMI [16:09] yeah thats why i use above extension and for inputs the https://extensions.gnome.org/extension/768/audio-input-switcher/ [16:12] iffraff: that's outside the realm of my knowledge... there are so many differenct factors from how you set up your dev environment, to what compiles, virtualizers and other tools you might have running. Most of which isn't really on-topic for this channel. I would suggest reaching out to a community more focused on mobile application development to see what advice they can offer in setting up your environment to be more efficient [16:13] pragmaticenigma: no, I get that, I know I'm probably running too much, or whatever, but my question is why would it throttle, when the cpus are in high utilization, and is there anything I can do about that? [16:15] iffraff: throttling occurs when the CPU detects internal hot-spots... this often happens when all cores are being utilised. The peak CPU clock ratings you see advertised are usually the max for a single core... when more cores are busy and heat builds up in indivudal cores they will be down-clocked [16:16] I see, and in a lap top is there anyway to cool them? would that allow them to ... work harder? [16:17] iffraff: a laptop in particular has limited ability to cool itself [16:18] so I run the laptop with the lid closed :) I have two external monitors, I suspect that might trap some heat? [16:19] I would expect so yes [16:20] I wonder if there's a way to run with the lid up but the monitor off. [16:21] iffraff: Yes, laptops often use the area around the keyboard to draw in air, was well as vent away heat... the lid down is trapping all that heat in the base. Keep the lid open. My work laptop for dev work is on a perforated monitor stand when it is docked so it has airflow all around. Lid stays open even though I'm using external monitors [16:21] it doesn't really feel warm to the touch [16:22] iffraff: is the laptop panel displaying anything even though the lid is closed? if not it could be disabled using "xrandr --output eDP-1 --off" or similar (use "xrandr" to get the output name) [16:23] pragmaticenigma: sounds like mine.. although I sank the perforated grill and fan into the bench itself [16:24] well, this is good info, seems I can turn built in mon off via displays gui, and I can maybe raise the lap top upa bit on some sticks or something. [16:25] I will keep an eye on performance and hopefuly this will help. [16:25] thanks [16:25] no my ram, that's anouther story. 16gig 92% in use [16:27] Hi people! [16:27] TJ- SLBS [16:27] I need help setting up RAID on my system. [16:28] I have 3x 1.5 TB disks and want to setup RAID 5. [16:29] I figured I would do something like this: [16:29] DISK 1: [16:29] - 1 GB efi partition [16:29] - 4 GB swap [16:30] - rest for RAID [16:30] !paste | super_koza [16:30] super_koza: For posting multi-line texts into the channel, please use https://paste.ubuntu.com | To post !screenshots use https://imgur.com/ !pastebinit to paste directly from command line | Make sure you give us the URL for your paste - see also the channel topic. [16:30] Also super_koza ... wait for someone responds to your question, if someone is able to help, they will reply to you in the channel [16:32] sure, will do [16:32] here is the partitioning that I had in mind: https://paste.ubuntu.com/p/h2m89MWCxg/ [16:34] is this good enough? I see a vulnerability here if a DISK 1 dies. This means I would have to have efi partition on each disk, but I am not sure how to setup this. [17:12] You can make an EFI partition and copy the contents across. Should work, but I've never done it. [17:13] But the boot entry on the motherboard will only point to one EFI partition at a time, so you might have to select the drive manually during boot if you get a failure. === gry_ is now known as gry [17:24] Sounds like that's one heck of an EFI-SP -- 1GB ! === SubZ3r0_Toxic is now known as CJ- [17:43] if i have a certificate chain with 3 certs in one file, each demarcated with the usual ---BEGIN---, etc... can i just dump this into /usr/share/ca-certificates/foo/bar.crt and have dpkg-reconfigure ca-certificates understand? or do i need to split it into 3 separate files? [17:44] NoImNotNineVolt: that is fine as a single file [17:45] sweet. awesome. then i'll give it a shot. [17:45] NoImNotNineVolt: oftentimes with CAs that have intermediates that is done with the host's cert [17:46] yea, in this case, i want to trust our team's intermediate, but it's signed by our org's intermediate (which doesn't roll up to a trusted root) [17:52] rehash: warning: skipping foo.pem,it does not contain exactly one certificate or CRL [17:53] but ha, it worked anyway. [18:07] NoImNotNineVolt: hmmm, that means the certs didn't get rolled up into the single /etc/ssl/ca-certificates.crt ... maybe policy has changed since I last had to do that. Best to check [18:15] super_koza, you could setup a raid 1 mirror for the efi partition, since you can only withstand losing one drive, you'd still have the efi partition, then when you replace the failed drive, it can rebuild the redundant efi partition naturally [18:16] I thought efi can't be on RAID at all... [18:16] I remember reading that somewhere [18:17] raid 1 is so simple it works [18:17] ot [18:17] it is just mirroring [18:17] EFI will work with RAID if the you have a hardware RAID controller. It will not work with Software Defined RAID [18:17] no need to do something special with reads [18:18] super_koza: couple of points 1) EFI_SP does not need 1GB ... more like 64MB ! [18:19] super_koza: also, if you're using mdadm software raid, and use metadata version 0.9 or 1.0, which puts metadata at end not beginning, you can safely do a RAID-1 of the EFI-SP [18:20] super_koza, see https://help.ubuntu.com/community/Installation/SoftwareRAID "Warning: the /boot filesystem cannot use any softRAID level other than 1 with the stock Ubuntu bootloader" [18:20] super_koza: in that case the PC's UEFI boot-manager ignores (does not know) about the RAID mirror it just uses a single device partition as normal [18:21] OK, I will try putting efi partition on RAID 1 across the 3 drives [18:21] Lets see what happens [18:21] super_koza: nice side effect is, you can manually use efibootmgr to add both halfs of the RAID-1 mirror to the boot menu, set one as default, if it ever dies you can simply select the other device from the UEFI boot menu [18:26] TJ-: That sounds great! Why halves, I've got 3 disks... :D [18:26] super_koza: mirrors usually only have 2 sides when they're on the wall :) [18:26] So I have swap in RAID 0, efi in RAID 1 and root in RAID 5 [18:26] super_koza, you don't need 3 - you are screwed if you lose more than one drive anyway [18:26] RAID-5 ? yurk [18:27] 3-disk RAID-5 is a disaster waiting to happen :) [18:27] Why? [18:27] I have 3x 1.5 TB [18:28] and I need ~2 TB storage :D [18:28] super_koza, I mean, don't need 3 drive efi mirror [18:28] test and see... rebuild times can be very very long [18:28] When you lose a drive, you now have a gap of replacing the drive and rebuilding, where the remaining drives, which are identical to the failed one are under heavy load. [18:28] sorry doug16k, I get you, good point [18:28] I have a 3-drive raidz, but that's at least ZFS. [18:28] And it's not for anything too important. [18:29] lordcirth_ and TJ-, so what do you suggest I do? [18:30] to avoid the issue of stressing the other two nearly failed drives, you can dd the two still working drives onto a full set of 3 replacements, and rebuild on the new fresh drives [18:30] super_koza, You could do a small raid1 rootfs, and the rest raidz, so at least you'd be safe from bitflips. You could also do a 3-way mirror. You'd only get 1.5 TB, but it'd be faster and safer. [18:31] 1.5 TB is just not enough [18:31] I need at least 2TB [18:31] and I am limited to 3 disks at the most [18:32] Why is that, not enough slots? [18:33] Yes, I am trying to make a home server out of an old HP SFF PC. [18:34] I have already populated both 3.5" drives and a 5.25" DVD drive. [18:34] Which means one of the drives is using a slower SATA standard... [18:34] But hey, I expect my network to be slower than the slower SATA so... :D [19:07]
