[02:26] gfshsdfgsgsdfg === genii is now known as genii-core [03:12] I have this crontab 00 15 * * * /usr/bin/python3 /root/app/ip.py but it does not get executed everyday at 15hrs. What could be the reason? [03:42] I feel like you're missing a dot somewhere [03:42] oh, no I guess not. hmm [03:46] https://gavinwiener.medium.com/how-to-schedule-a-python-script-cron-job-dea6cbf69f4e <- down at the bottom here they talk about running the script explicitly instead of calling python and pointing it at the script. [03:46] That might help? [03:46] oh, right, tagging people xD dba - that's for you [03:48] thanks Kel, I did some research and I'v learn the crontab does not work if there were some output generated by the script so I did >/dev/null 2>&1 but still does not work [03:49] Oh... huh [03:52] Unfortunately CRON isn't a thing I've had much need for over the years, so I'd be in the same boat as you with looking it up as I go along, and I don't know your full context so I can't really help much I think. [03:52] I will assume you've tested the script and the script works? [03:52] like - perhaps cron is doing what it's supposed to, but the problem is actually the script? [03:54] Kel, the script works fine. I never had issues with cron neither nohup but now also nohup doesnt seems ot be working as well [04:14] dba: where did you put that crontab line, in `crontab -e`, in `sudo crontab -e`, or in /etc/cron.d? === popey2 is now known as popey [08:19] and it won't stop working if there's output.

If I close and open again my browser those pinned tabs are not present anymore [12:09] On my Mac it works properly [12:14] is there a way to use the same id_rsa to log onto multiple accounts on the same remote server [12:14] right now my id_rsa works for root@host.com but not user@host.com [12:15] I want to be able to log in to user@host.com as well [12:15] Then you have to put your private key into that user's authorized_keys file too [12:15] Oops [12:15] Public of course [12:16] oh okay, that makes sense [12:19] nice it worke [12:19] worked [12:24] in ubuntu calculator, is there a way to scroll through history using keyboard instead of mouse? [13:26] hey [13:26] anyone got experience with dnsmasq ? i want to run the dhcp server but it says in the log that a dhcp packet received on eth1 which has no address [13:27] i assume this is because i do not have a address currently set on eth1 [13:27] but how do i fix this? [13:27] i know how to set a ip address for example with ifconfig but then dnsmasq can't hand out dhcp anymore [13:28] sys that there is no room in the range or something [13:28] "no address range available" [13:30] Daulity: which version of ubuntu? [13:31] 20.04 [13:36] ducasse: which ip address is on eth1 and please pastebin your /etc/default/dnsmasq and /etc/dnsmasq.conf or if you edited something in /etc/dnsmasq.d/* [13:37] sorry, Daulity [13:37] no address on eth1 [13:38] Daulity: step #1 set a static ip address on the interface you want dnsmasq to listen on (make sure that interface isn't plugged into a network with a DHCP server/router already) [13:38] give me a moment to create the pastes [13:41] leftyfb: step #1 is important [13:41] xD [13:41] I thought dnsmasq would set the interface [13:41] for some reason [13:48] Daulity: you set which interface or address to listen on in the config.

I'm curious if someone here might be able to help me out. I went to the xen irc channel but no one there is responding. I installed xen in ubuntu 20.04.2 LTS but I get an error "panic on cpu 0 + timer doesn't work" [16:39] golden_ticket: it'll be good to explain what you did exactly to get this error message, and what hardware you're running on (CPU and RAM mostly). and of course, your ubuntu version and kernel version. [16:41] tomreyn: I ran "sudo apt-get install xen-hypervisor-amd64" and then rebooted. I'm using asus zenbook. I'm using and i9 processor and idk what kind of ram [16:41] tomreyn: thanks for the input === Ricardus_ is now known as Ricardus [16:43] golden_ticket: your ubuntu release / version and kernel version? cat /proc/version_signature; grep PRETTY /etc/os-release [16:44] Ubuntu 5.11.0-36.40~20.04.1-generic 5.11.22 [16:44] PRETTY_NAME="Ubuntu 20.04.2 LTS" [16:44] vmstat -s | head -1 [16:44] 32684560 K total memory [16:46] golden_ticket: so you got the "panic on cpu 0 + timer doesn't work" error message during installation of the package, or during reboot, or when? [16:46] During reboot. Installation went fine (I assume). As I didn't have to reboot during installation. [16:46] I rebooted after it installed. [16:48] this isn't you, is it? https://askubuntu.com/questions/1271889/why-cant-i-book-xen-hypervisor-on-ubuntu-20-04-1-panic-on-cpu-0-timer-doesnt [16:49] Haha! Yeah that's me all right. I did find a solution a year or so ago from someone on IRC that involved modifying "dogwatch" as I recall. [16:50] there are "watchdogs", i don't know "dogwatch" [16:50] Ah [16:50] Sorry. [16:50] I meant watchdog [16:50] is secure boot disabled? [16:50] tomreyn: I'm not sure. How do I check? [16:51] you grab your mainboard / laptop manual and look it up [16:51] Ah via bios? I can boot into it and check [16:51] I'll have to leave IRC though and come back [16:51] you should get a second computer / smartphone / tab or whatever [16:51] but yeah, give it a try === golden_ticket is now known as golden_ticket_pc [16:53] Okay I'm on via my phone [16:53] Rebooting laptop now [16:54] Secure boot is disabled [16:54] As is fastboot [16:54] in case it persissts, if you can get a screen shot of the error message, that'll get you extra points. [16:54] because "panic on cpu 0 + timer doesn't work" is not an exact quote [16:54] Okay [16:54] The best I can do is a phone pic [16:55] which is fine, just upload it to imgur.com or something and post the link here - 5 or so characters to type. [16:56] https://ibb.co/6mnKZ2P [16:56] Here's a screenshot [16:57] so you were chatting from the same computer here but also got this critical sounding error message,. how did you achieve this? did the system keep booting after it? [16:57] I booted to the normal kernel rather than the hypervisor [16:57] direct link (for anyone following) https://i.ibb.co/zrn351R/20210923-115600.jpg [16:58] Okay I'm booted back in [16:59] so the error message does say what you should try, did you try this?

I like using the hypervisor [17:00] I did try to boot with napic option, didn't help [17:01] t's "noapic" [17:01] it's "noapic" [17:01] Oh. typo [17:01] Sorry I meant I booted with noapic [17:01] now or when you tried? [17:01] just now [17:02] did you look for bios updates? [17:02] no. Should I try updating bios? [17:02] if virtualization fails with acpi-like errors, that's amongst the first things i would try. [17:03] Ah [17:03] I didn't know that [17:03] let me check bios, thanks [17:03] I'm still here [17:03] Version 308 (release date 2020/07/15) is the latest [17:03] UX581GV.300 will be version 300 [17:04] I have version 300 [17:05] that's what i meant to say, [17:05] Oh I see [17:05] Okay so step one is updating bioa [17:05] Bios* [17:05] the changelogs towards 309 are not useful, just say "Optimize system performance". but this could well cover this.

[17:10] I think so [17:10] Nvm yeah [17:11] yes most likely [17:11] you'll need to place it on a fat file system. storing it on your existing EFI system partition can also work [17:12] Thanks [17:14] Upgrade in process [17:18] Same error on boot [17:19] golden_ticket: so when you passed the noapic option during boot, how did you do it? which line did you edit, how? [17:20] Now we have a new issue. Booting to the normal kernel does not work. It instead boots into busy box [17:20] Wth [17:20] Why would upgrading bios do this? [17:20] does it say? [17:21] It just gives me a busy box shell [17:21] Ah [17:21] Here we go [17:21] did you make sure to reconfigure the bios like it was before the upgrade? [17:22] https://ibb.co/njZgmT9 [17:22] No [17:22] Good point [17:22] Let me go back and check bios [17:22] direct link to image https://i.ibb.co/x6PCLyW/20210923-122131.jpg [17:25] Hmm [17:25] the cpi error you encountered is not usually fatal, i.e. boot would normally continue [17:25] *acpi error [17:26] Well I modified bios to be back how it was and the issue persists [17:26] It throws this error and boots to busybox [17:26] does this output anything - in busybox: echo $REASON [17:26] Sorry I reconfigured bios, didn't downgrade it [17:27] Yes it does [17:27] and that is? [17:27] It says alert uuid=series of characters does not exist! Dropping to shell! [17:27] So the uuid has changed [17:28] apparently grub is unable to find the configured partition which contains its / file system [17:28] i mean linux's, not grub's [17:29] maybe raid/ahci bios option? [17:29] do laptops have this? [17:29] I don't think my laptop even has more than one hdd [17:29] Or whatever kind of disk drive it is [17:29] well it's worth looking for either way [17:29] Okay [17:29] anything about ahci at all golden_ticket ? [17:30] feel free to take screen shots of any bios screens [17:30] No. Busy box doesn't say anything about ahci [17:30] Okay [17:30] no i mean in the bios options [17:30] I'm about to check [17:32] https://ibb.co/DWcG0Yn [17:33] https://ibb.co/7gm14y5 [17:33] https://ibb.co/NVF7JgC [17:34] https://ibb.co/VWnmtMY [17:34] https://ibb.co/Q9vvGPB [17:35] https://ibb.co/rthZnds [17:35] Those are all of the pictures [17:35] is doing apt-get update everytime is a good thing? [17:35] since yesterday we are facing some slowness in network [17:36] Fdan I don't think doing apt-get update will solve network issues [17:36] it will not solve ofcourse [17:36] I may be wrong [17:36] my guess is will it break stuff [17:36] is it generally a good thing to do apt-get update always [17:36] or does that mean something gets updated and things can turn wrong 10% of the times [17:37] I don't consider that a wise decision from a security point of view. Generally letting software sit for a while and have the latest version tested is the better option. Unless the update is security related [17:37] could someone tell me why we are facing some random network issue [17:37] fdan, i'd say 1% of the times (not 10%) [17:38] we're facing this 2 days now [17:38] tomreyn EriC^^ did you see my bios pictures? [17:39] yeah, they look fine to me [17:40] I thought so. Why would uuid change? [17:40] golden_ticket: did you try booting a different kernel entry in grub? advanced > choose some older kernel [17:40] Hmm I believe that won't work but let me try [17:41] The issue persists with older versions of the kernel as well [17:41] EriC^^ [17:42] fdan: there's #ubuntu-mirrors for know issues on the ubuntu repos if you wanna doublecheck [17:42] golden_ticket: maybe see in /dev or similar dir what disks are there/uuid [17:42] when you drop to the busybox [17:42] Okay. [17:43] How do I navigate busybox? I don't know commands [17:43] Is it the same as Linux kernel? [17:43] yeah it's pretty similar to bash i think, like a compressed bash [17:43] Ah [17:43] Okay thanks [17:44] Okay I'm in /dev [17:44] Now what? [17:45] any sda1,2 etc? [17:45] No [17:46] Let me recheck [17:46] go to /dev/disk [17:46] ls /dev/disk/by-uuid [17:46] No such file or directory [17:46] this may or may not be there/populated, yet [17:47] I see [17:47] according to https://i.ibb.co/yPvhHpJ/20210923-123205.jpg you usually boot off (the EFI system partition, specifically, is on) a Samsung SSD [17:48] Ah [17:48] golden_ticket: anything in "cat /proc/partitions" ? [17:48] a Samsung MZVLB1T0HALR PM981 NVMe 1 TB M.2 PCIe SSD [17:49] so it will be /dev/nvme* [17:49] EriC^^ no [17:49] Let me check [17:50] I don't see any nvme directory [17:50] it won't be a directory [17:50] Or file [17:50] and "nvme" is just part of the name [17:50] Yeah [17:50] Nothing with that in the name [17:51] Sorry for the lack of elaboration on my replies. Hard to text with stupid auto correct [17:51] It keeps messing everything uo [17:51] Up* [17:51] does your bios list the drive? [17:52] check what's in I/O security here https://i.ibb.co/PTH6QCn/20210923-123158.jpg [17:52] Okay [17:52] seems on google the most common problem is MB switched ahci off by default, or having csm legacy enabled [17:53] if there is an "M.2" or "PCI(e)" or "NVM(E)" or "SSD" option this may need to be enabled [17:53] is sata settings here related or not cause of nvme? [17:53] Okay hold on [17:53] sata > ahci stuff [17:54] maybe worth a shot to see what's in the 'sata configuration' menu [17:54] on https://i.ibb.co/d0Cgrk4/20210923-123144.jpg "Intel Rapid Storage Technology" needs to be disabled, if that's an option [17:54] Io seucirty just has HD audio interface, wireless network interface and usb interface security [17:55] Okay hold on let me check [17:55] So I'm under advanced/sata configuration [17:56] Sata mode selection is Intel rst premium with Intel optane system acce [17:56] So I need to set it to ahci? [17:56] try ahci, why not, also see tomreyn 's suggestion on intel rapid storage [17:56] right you have intel RST enabled, that'S the problem. i just noticed it on https://ibb.co/rthZnds as well [17:56] "PCIE RST Controlled Disk" [17:56] Ah [17:57] Booting with ahci noq [17:57] Now* [17:57] Okay it can boot now. Yay! [17:57] Thanks guys [17:58] So now let's get back to the original issue. Booting with the hypervisor [17:58] what does "Booting with ahci now" mean? [18:00] Ahci was a model selection under sata configuration [18:00] AHCI is the native interface of the SATA controller. [18:01] In some BIOS setup utilities, you can select the SATA interface between IDE mode and AHCI mode [18:01] golden_ticket: ah so you were referring to the bios option which eric had hinted at, ok. [18:02] Sorry for not being clearer [18:02] no worries, i was just wondering whether you're setting a kernel option there, or passing one to xen, or something else [18:03] Okay so let's go back to trying to boot with the hypervisor. Where were we tomreyn? [18:03] so your grub record for xen booting, what does that look like now? [18:05] Is there a way to check grub for xen while booted into Linux? I'd rather send you pastes from terminal rather than a shaddy pic [18:06] you can cat /boot/grub/grub.cfg | nc termbin.com 9999 [18:07] or copy and paste just the relevant part to a pastebin [18:07] either works [18:07] Thanks [18:07] One moment [18:08] https://github.com/QubesOS/qubes-issues/issues/5374 can be related. this still looks like an a hardware/system firmware oddity [18:08] Issue 5374 in QubesOS/qubes-issues "Xen causes kernel panic during install - USB boot" [Closed] [18:08] qubes is a linux distribution which makes use of xen [18:08] they have live cd's, so you could use those to test different xen versions [18:08] https://termbin.com/6ovf [18:10] when you passed the "noapic" option, how did you do this exactly? [18:10] tomreyn: Hm. let me check to verify how I did it [18:10] I think I did it correctly but let me check [18:11] it's not in your grub.cfg, so i assume you edited it from the grub menu? [18:11] yes [18:12] when booting with xen, hardware sepcific options such as noapic need to be passed to xen rather then linux, i.e. on the line which invokes the xen HV [18:12] did you pass it there? [18:12] I passed it to the grub entry for the xen hypervisor, yes [18:13] so you edited the line saying multiboot2 /boot/xen-4.11-amd64.gz placeholder ${xen_rm_opts} ? [18:13] If you want I can boot into grub and check specifically where I did it. [18:14] Should I? [18:15] sure, whatever helps [18:16] i don't doubt you, i'm just trying to understand what exactly was done [18:16] I understand lol. I too want to make sure that this is correctly done. It's very possible I made a mistake [18:17] pls hold [18:17] I did it on the line where quiet splash is listed [18:17] I did it in between ro and quiet splash [18:18] I typed acpi=off noapic [18:20] tomreyn does my paste from earlier show that line? [18:22] golden_ticket: which one exactly? [18:23] The termbin paste [18:23] I think there is only one [18:23] "quiet" and "splash" are passed to linux / its initrd, so that's the wrong line. [18:24] Ah so I did do it wrong [18:24] Where should I do it? [18:24] https://termbin.com/6ovf does not contain "noacpi" [18:24] Interesting [18:24] err "noapic", sorry [18:24] it contains neither [18:24] Let me take a pic of what I'm looking at [18:25] https://ibb.co/CJ5B7TG [18:25] Here is a photo [18:25] you need to add "noapic" to the end of the line saying "/boot/xen-4.11-amd64.gz" [18:25] Ahhh [18:25] Okay [18:27] Computer is extremely slow in grub. Pls hold [18:28] Booting now [18:28] Error occured [18:28] It just rebooted [18:28] Same error as before [18:31] can you sudo apt install xen-hypervisor-amd64 [18:31] Yes [18:31] just to make sure we're not missing anything [18:31] does it install additional packages? [18:32] 0 upgraded 0 newly installed [18:32] do you have any "XEN" options in /etc/default/grub ? [18:32] Let me check [18:33] No I don't [18:33] you can add GRUB_CMDLINE_XEN_DEFAULT="noapic" there [18:33] Okay [18:34] i think this still applies https://serverfault.com/questions/299877/how-do-i-add-xen-kernel-boot-parameters-in-grub2 [18:35] try also hpet=0 [18:36] Error persists. Where do I put hpet=0? [18:37] same line on interactive grub, and same (XEN) option on /etc/defaul/grub - see what comes out of it when you "sudo update-grub", at /boot/grub/grub.cfg behind the line saying "### BEGIN /etc/grub.d/20_linux_xen ###" [18:38] Also I updated the grub like you said before but did not "apply" the changes but I did save the file. Do you think that is why it isn't showing up in grub menu? [18:38] yes [18:39] if you edited /etc/default/grub this does nothing until update-grub is run [18:39] I didn't do that. Let me boot back and run update-grub [18:41] Okay a new error occurs [18:41] update-grub is a wrapper around grub-mkconfig, which in turn parses and interprets /etc/default/grub, and creates /boot/grub/grub.cfg from the values sepcified there, using templates stored at /etc/grub/grub.d/ [18:42] actually /etc/grub.d/ [18:43] for xen, it specifically uses /etc/grub/grub.d/20_linux_xen (and notes this in the configuration file it writes to /boot/grub/grub.cfg ) [18:43] It disappears too quickly to take a picture but it says panic on cpu 0 and general_protection_fault [18:43] So now I need to do the additional change you mentioned [18:46] I put hpet=0 next to noapic in grub and upstated grub [18:46] Booting now [18:46] i think it's easier to test these changes by editing them live from the grub menu [18:46] Error persists :/ [18:47] after all you should be able to see where it really belongs now that you put the XEN* option into /etc/default/grub [18:47] can you post your grub.cfg again? [18:47] Sure [18:47] i.e. the generated one [18:48] https://termbin.com/pf4h [18:48] but i think ths really boils down to either needing a newer xen version which has this fix, or a different computer, or more tweaking to work around the bios bug [18:48] Golden tick lol [18:49] Hm [18:49] I tried contacting people in the xen irc room but no one replied :/ [18:49] Let me see if anyone is there now [18:49] channel* [18:50] oh, something else you could try is to switch the default graphics chipset away from nvidia and to intels [18:50] Ohhh yeah [18:50] I didn't do that [18:50] that would need to be done on your bios [18:50] I thought you can do that from within ubuntu though? [18:51] apic_verbosity=debug as a xen option could also help [18:51] you should set it on the bios in this case [18:51] okay let me try real quick [18:51] the graphics chipset priority, that is [18:52] i need to take a food break, bbl [18:53] Thanks [18:57] hello [18:57] tomreyn the fix appears to be booting into legacy mode and not uefi. But my computer cannot do this [18:57] i'm on lubuntu or xubuntu, the former i think, and it would be a 20.04 version then according to /etc/os-release ... i cant find a package when doing this, sudo apt install libcupsys2-dev do you think this is normal? === Tabstar is now known as Tabmow [19:14] ok so libcupsys2-dev has probably changed name or so [19:24] sybariten, what are you trying to install? [19:26] coconut: cups, in one way, and in the long run a rather niche printer [19:27] sybariten, that probably is libcups2-dev now(just checked that for hirsute) [19:27] coconut: i got it in and it seems to be running now [19:27] ok [19:27] thanks coconut [19:27] yw [19:29] I would like to rename core dumps, it is possible to tell Apport to use a different name then `core` ? [19:29] roussinm: why? [19:30] roussinm: you can remove apport and whatever from the system if you wish to do something with the cores yourself [19:31] I don't mind keeping Apport, I'm sure it's useful I didn't really go in-depth into the python script to see what it does, but if I could tell it add timestamp to it, it wouldn't replace already present core dumps [19:39] sarnold: Actually, I think it does not replace an already present 'core' file. [19:40] roussinm: heh, I haven't actually had just simple 'core' files in *ages*, I can't recall how it actually works :) [19:40] roussinm: look up /proc/sys/kernel/core_pattern in core(5), that'll describe how you can name cores with more fields [19:41] Can anyone help me with applying this patch to xen? https://eengstrom.github.io/musings/booting-xen-on-ubuntu-via-grub-with-uefi [19:42] tomreyn: you there? [19:42] I think I found a solution [19:43] sarnold: yes I looked at it, there is a feature inside apport where it can append the pid of process to the name. I guess I will completly override the string inside /proc/sys/kernel/core_pattern [19:47] sarnold: what's the core_pattern are you using? [19:47] roussinm: I think it's just the default, |/usr/share/apport/apport %p %s %c %d %P %E [19:48] So if you generate a core dump it will dump as `core` no? === Osares100 is now known as Osares10 [19:51] sarnold: maybe you modified /etc/sysctl.conf:kernel.core_pattern [19:52] roussinm: that string is straight from /proc/sys/kernel/core_pattern [19:53] Hmm ok, I'm not sure if /etc/sysctl.conf modifies what's being shown in /proc/sys/kernel/core_pattern.
