| zcot | Yakov: make sure that file has executable permission, try with terminal: chmod u+x /home/supernova/build-Probe_App-Desktop_Qt_6_2_4_GCC_64bit-Debug/Probe_App (alternately you can right click that file in File Manager to allow executable permission) | 02:32 |
| Yakov | permission set before, and set your variant, same icon on .desktop file same error | 02:33 |
| zcot | Yakov: i am not familiar with the program. maybe you need to set the base directory. maybe the desktop file will need: sh -c 'cd /home/supernova/build-Probe_App-Desktop_Qt_6_2_4_GCC_64bit-Debug && ./Probe_App' | 02:36 |
| Yakov | indeed, if i put .desktop file to corresponding folder it has no x mark on icon | 02:46 |

| Siamaster | Hi, I'm trying to understand why my port is not open whether the problem is from my router which I suspect or I've forgot something. I've started a server on port 3000 and when I do sudo netstat -l I get this row: tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN | 07:49 |
| Siamaster | This means I've opened it correctly to be accessed from the WAN right? The problem should be the router | 07:50 |
| Siamaster | I can access the server from 192.168 | 07:50 |

| tk_ | Any help on how to solve the issue would be nice | 07:56 |
| tk_ | @Siamaster If U can access the server on the LAN using that port but not on the WAN. Then chances are port forwarding on the Router is not well done | 08:04 |

| DocMors | good evening, can someone tell me how to globally change the DNS servers? I have some 20 odd WIFIs I use on a regular base and I'd rather not modify each one seperately. The setting I'd pick if I used the network manager would be DHCP Adresses Only. Is there a global config I can use to set the standard? It's on 20.4 | 08:20 |
| tk_ | weedmic Yeah it is a repetition | 08:22 |
| weedmic | when you boot into the pre-exsiting older kernel, did you review dmesg? did you check your "networks" to see if anything is even setup? You might want to reword your question as a lot of helpers here do not speak english very well. | 08:25 |
| weedmic | DocMors: do you have ansible? are all these items in inventory? | 08:26 |
| DocMors | no they are in the standard network manager, nothing to do with any containers | 08:27 |
| tk_ | weedmic so basically I have configured Bond on two 10gig ports having bond0.13 and bond0.3004 but when I boot into the kernel .. I have found out that when I run the command ip a .... I can see the bond0 and 0.13 plus 0.3004 interfaces but the physical 10 gig interfaces are not there | 08:29 |
| tk_ | I doesn't recognize them I think | 08:29 |
| tk_ | weedmic To add on that, The older kernel is not pre existing ... I had to install it | 08:31 |
| weedmic | if you had ansible and they were all in the inevntory, it would be one command - but perhaps I don't know what you are trying to do DocMors | 08:31 |
| DocMors | weedmic, when a new connection is created with network manager it follows a 'template'. By default it's using DHCP, I would like to know where this template is and modify it to DHCP Adresses Only | 08:33 |
| weedmic | well, there is system settings>connections>default tab - but I thought you had machines in other places you wanted to change the dns servers on - this now sounds like you just want to make conneciton easier on one machine. | 08:36 |
| DocMors | no I want to change the settings on my laptop for about 20 WIFI networks all over the place | 08:37 |
| Square2 | weedmic, thanks. I got it to work eventually. | 08:39 |
| weedmic | I hope it was easy Square2 - it's supposed to be easier than windoze now. | 08:49 |
| gordonjcp | DocMors: can't you add your DNS settings in the system's resolver settings? | 08:52 |
| gordonjcp | DocMors: what exactly are you trying to do? Normally DNS would be supplied by DHCP anyway | 08:52 |
| tk_ | weedmic Do U think U can assist ? | 08:57 |

| Terminal-V | AES-256-CBC is available. Does anyone know what's up with this? | 09:12 |
| DocMors | not "DHCP" but "DHCP Adresses Only" | 09:13 |
| DocMors | gordonjcp, and where do you find these 'system's resolver settings' | 09:14 |
| gordonjcp | <shrug> | 09:14 |
| gordonjcp | it's not something I generally find I need to tamper with | 09:14 |

| gordonjcp | DocMors: I've no idea what problem you're trying to solve, so there's no easy answer | 09:16 |
| DocMors | I know how netplan works but that isn't helping me with this. Since Network Manger doesn't really care | 09:18 |
| DocMors | if I was on a server without gui, that would be easy | 09:18 |

| leftyfb | brianc: push what exactly? | 18:41 |
| brianc | The bug currently is unassigned | 18:41 |
| leftyfb | brianc: If there's no fix, what do you want "pushed"? | 18:41 |
| leftyfb | brianc: ok, you'll have to wait till it gets assingned | 18:42 |
| leftyfb | brianc: FYI, this isn't Canonical support. This channel is run by community volunteers | 18:42 |
| brianc | The bug is almost two years old now, and seems to affect 20.04 and 22.04. mdadm is a pretty major feature for that big of a bug to hand around that long. | 18:43 |
| leftyfb | brianc: feel free to add to the bug with any new information that might help the maintainers resolve this issue | 18:44 |
| brianc | I already have. You can check what I have added. | 18:45 |
| leftyfb | brianc: you could try reaching out to the kernel team https://lists.ubuntu.com/mailman/listinfo/kernel-team | 18:46 |
| BarnabasDK | brianc, I know it is not a fix for your current issue but consider zfs | 18:52 |
| brianc | OK thanks I will try that. This bug really deserves some attention. We are having to disable RAID checks on systems we can not physically reach will this is pending. | 18:52 |
| brianc | We thought about zfs, but have not gone that direction. I read something recently that kind of put me off it, I think the number of disks required to make is useful. | 18:54 |
| BarnabasDK | brianc, having used raid 5 and zfs, I will have to say zfs is superior in every way - just much more flexible - and you can still run with parity if you want to | 18:56 |
| BarnabasDK | ofc, if you chose mirroring, you use more disk | 18:56 |
| iphorde | BarnadsDK: Except performance. ZFS is slow a snot. | 18:56 |
| BarnabasDK | so is raid5 | 18:56 |
| iphorde | Compared to ZFS, no it isn't. | 18:57 |
| iphorde | You have no idea what you're talking about. | 18:57 |
| brianc | BarnabasDK: Our RAID5 only has 3 disks in most cases. | 18:57 |
| BarnabasDK | well, if you want performance you will choose neither | 18:57 |
| brianc | Slow would be bad as well, we find RAID5 performance good, and believe me I have tested a lot. | 18:57 |
| BarnabasDK | iphorde, I think I do .. | 18:58 |
| iphorde | You think, and you're wrong. | 18:58 |
| leftyfb | iphorde: BarnabasDK please take the RAID/zfs debate elsewhere | 18:58 |
| BarnabasDK | I have no intention of getting into such a debate | 18:58 |
| el | save | 18:58 |
| BarnabasDK | brianc, fast for reads slow for writes | 18:59 |
| BarnabasDK | so with regards to speed - the correct answer is - it depends | 19:00 |
| brianc | leftyfb: I didn't realize this wasn't an official Canonical support channel, thanks for letting me know. | 19:01 |
| leftyfb | brianc: Canonical doesn't do support through IRC. https://ubuntu.com/support/contact-us | 19:02 |
| iphorde | BarnabasDK: You made a claim, "in every way", and now it depends. Look, quit giving bad advice. | 19:02 |
| leftyfb | !ot | iphorde | 19:02 |
| ubottu | iphorde: #ubuntu is the Ubuntu support channel, for all Ubuntu-related support questions. Please use #ubuntu-offtopic for other topics (though our !guidelines apply there too). Thanks! | 19:02 |
| BarnabasDK | iphorde, you where advised to take the debate elsewhere wherent you? | 19:02 |
| BarnabasDK | what don't you comprehend? | 19:02 |
| iphorde | You're an idiot. | 19:03 |
| leftyfb | iphorde: that's enough | 19:03 |
| brianc | Sorry guys, I didn't mean to start a flame war. I'm out of here. | 19:03 |
| BarnabasDK | iphorde if you say so it is probably true | 19:03 |
| BarnabasDK | I can only say on the disks systems I have managed overall raid 5 and zfs is slow - as compared to more expensive hw driven alternatives like raid 10 - let it be left at that | 19:06 |
| BarnabasDK | brianc, no flame war on my part | 19:08 |
| brianc | OK I've managed to reach a live body at Ubuntu and we'll see how that goes. Not sure the kernel team is the right place for what seems to be an mdadm bug so I haven't posted a question to them yet. If anybody else runs into this "kernel io hangs during mdcheck/resync" bug #1942935 please please add a comment to it. It would have just happened as | 19:45 |
| brianc | the raid check is run the first Sunday of the month by default. We just saw it again, and also the last couple of months. We have had to take the drastic step of disabling RAID check because some of our servers are very remote and the only way to recover them would be to physically be there to reboot them. Thanks. | 19:45 |

| Muligan | has anybody suggestion as to adding an IP address to the loopback interface via netplan? | 20:11 |
| leftyfb | Muligan: why? | 20:11 |
| Muligan | fyi, working on ubuntu 18.04 still | 20:11 |
| Muligan | leftyfb, because of some crazy routing needed within our network | 20:12 |
| leftyfb | !eol | sorry, but Ubuntu 18.04 is EOL | 20:12 |
| ubottu | sorry, but Ubuntu 18.04 is EOL: End-Of-Life is when security updates and support for an Ubuntu release stop.

| leftyfb | Muligan: loopback has nothing to do with routing | 20:12 |
| leftyfb | Muligan: loopback is local to the machine only and has nothing to do with the network beyond the machine | 20:12 |
| Muligan | leftyfb, thank you for the clarification, but in my case, it is needed in regards to routing a /32 | 20:13 |
| scottpedia | loopback's not achieved by custom routing right? | 20:14 |
| leftyfb | Muligan: again, routing has to do with communicating with devices that aren't your machine or not on your network, including /32 | 20:14 |
| scottpedia | Muligan: are you trying to route certain traffic destined to a /32 block back to the same machine? | 20:14 |
| leftyfb | Muligan: that said, the loopback device has all of the /8 loopback addresses assigned to it | 20:15 |
| leftyfb | Muligan: case in point, ping 127.254.211.1 | 20:15 |
| Muligan | leftyfb, I appreciate it, but not looking for lessons on networking, the use for this /32 assigned to the loopback is necessary for the necessary resources to be reached | 20:16 |
| Muligan | leftyfb, and this aren't rfc1982 ip's either | 20:16 |
| leftyfb | Muligan: the loopback is a /8, not /32. The /32 is for a network interface having absolutely nothing to do with the loopback | 20:16 |
| Muligan | ^these rather | 20:16 |
| Muligan | this loopback IP address IS /32 | 20:17 |
| leftyfb | Muligan: then it's not the loopback device | 20:17 |
| leftyfb | Muligan: why create a whole separate loopback device when you already have 1? | 20:17 |
| Muligan | because on the source network's routing table is built with the /32 and the dest is the IP address of a physical interface | 20:17 |
| scottpedia | /32? ain't that a single address? leftyfb | 20:17 |
| Muligan | scottpedia, sure is | 20:17 |
| leftyfb | scottpedia: yes | 20:17 |
| Muligan | leftyfb, simple, because I want the IP to respond to the route | 20:18 |
| Muligan | without moving the subnet from a whole other part of the network | 20:18 |
| leftyfb | Muligan: loopbacks do not route | 20:18 |
| Muligan | I've done this plenty of times with centos | 20:18 |
| Muligan | leftyfb, I don't need it to route | 20:18 |
| Muligan | that's what my routers do | 20:18 |
| scottpedia | Muligan: okay i think if you eloborate your case clearly we might be actually able to help you | 20:19 |
| leftyfb | and yet you keep mentioning route in the context of your loopback | 20:19 |
| leftyfb | I don't don't understand what it is you're trying to accomplish | 20:19 |
| Muligan | how to permanently assign another ip (in my case, a single IP/32) to the loopback of this machine | 20:19 |
| leftyfb | you don't | 20:19 |
| === N4zroth74 is now known as N4zroth | ||
| scottpedia | Muligan: assign to the loopback? | 20:20 |
| leftyfb | the loopback is a predefined /8 | 20:20 |
| Muligan | then it can be a virtual interface for all I care | 20:20 |
| scottpedia | ok so you are tring to get the same result of $(ping 127.0.0.1) when you do $(ping x.x.x.x)? Muligan | 20:20 |
| leftyfb | Muligan: great, now we're getting somewhere. I feel like you were using the term loopback incorrectly and that was confusing everything | 20:21 |
| leftyfb | lets scratch loopback and 127.255.255.255 from the record | 20:21 |
| leftyfb | Muligan: ok, so you want to create a network interface with multiple ip addresses correct? | 20:21 |
| scottpedia | a virtual interface is what you gonna look for | 20:21 |
| leftyfb | or a bridge | 20:22 |
| scottpedia | you can do this yourself with tun/tap | 20:22 |
| Muligan | https://pasteboard.co/IjMQ7DcZcXiu.png | 20:22 |
| leftyfb | Muligan: does the interface only need to communicate locally to the machine and not over an actual network? | 20:22 |
| leftyfb | Muligan: the pastebin you just posted in blasphemy. Lets never speak of it again | 20:23 |
| Muligan | this is a screenshot from a centos7 box | 20:23 |
| Muligan | let's never speak of a working situation? | 20:23 |
| scottpedia | leftyfb: blasphemy? | 20:23 |
| Muligan | wow | 20:23 |
| scottpedia | Muligan: well your scenario is quite interesting | 20:23 |
| leftyfb | assigning routable ip's to the loopback | 20:23 |
| scottpedia | i've never seen anything like it | 20:23 |
| leftyfb | Muligan: does the interface only need to communicate locally to the machine and not over an actual network? | 20:23 |
| Muligan | scottpedia, working for an ISP, the networking is always interesting | 20:23 |
| Muligan | with a /32 route within our BGP core pointed to the physical interface's assigned interface, using the config above, with the public /32 IP assigned to the loopback, the traffic is able to reach this server | 20:25 |
| leftyfb | whoever did that needs to be fired | 20:25 |
| leftyfb | setup a virtual interface or a bridge | 20:26 |
| Muligan | scottpedia, I think you're on the right path for recommending this be built utilizing a virtual interface ( | 20:26 |
| scottpedia | leftyfb: bro | 20:26 |
| scottpedia | https://imgur.com/a/Dt6hpbS | 20:26 |
| scottpedia | it fucking worked | 20:26 |
| scottpedia | it's just that simple | 20:26 |
| Muligan | leftyfb, could you further clarify the reasoning for the suggestion of firing somebody? | 20:26 |
| leftyfb | worked != correct or free from exploitation, ESPECIALLY on a system serving up BPG routes | 20:26 |
| Muligan | lmfao | 20:27 |
| Muligan | this server does NOT serve up BGP routes | 20:27 |
| leftyfb | BGP* | 20:27 |
| Muligan | it's a simple endpoint | 20:27 |
| Muligan | we use these /32's from time to time when consolidating IPs, or moving them around the network freely | 20:27 |
| leftyfb | regardless, there is zero reason to add routable ip's to the loopback. Use a virtual interface or bridge | 20:27 |
| Muligan | based on what? | 20:29 |
| scottpedia | Muligan: well yeah | 20:29 |
| leftyfb | Muligan: with netplan, you can just add an ip address to an interface | 20:29 |
| leftyfb | no need for a virtual interface | 20:29 |
| scottpedia | i mean this kind of scenario's gotta be done with tun/tap Muligan | 20:29 |
| scottpedia | language of implementation is your choice | 20:29 |
| leftyfb | it's not necessary | 20:30 |
| leftyfb | just add an ip to the interface with netplan | 20:30 |
| leftyfb | netplan doesn't require virtual interfaces/aliases like ifupdown used to | 20:30 |
| leftyfb | Muligan: https://devicetests.com/configuring-multiple-ip-addresses-ubuntu-server-2004-netplan | 20:30 |
| scottpedia | ohh | 20:31 |
| scottpedia | interfaces.d that kind of stuff? | 20:31 |
| leftyfb | no, netplan | 20:32 |
| scottpedia | yeah I think it's gonna work | 20:32 |
| scottpedia | yeah now it's called netplan I think | 20:33 |
| scottpedia | it's been a while since I had to manually configure addresses on ubuntu | 20:33 |
| scottpedia | so my mind is frozen in the age of 1604 | 20:33 |
| Muligan | leftyfb, added to the interface, deleted the 'virtual interface' that was originaly created, 'netplan apply' was ran, and we're still responding | 20:34 |
| leftyfb | Muligan: ok, you're going to need to provide way more context as to what it is you're trying to accomplish. Be very detailed. | 20:35 |
| leftyfb | Muligan: "still responding" <~~~ is this the preferred outcome or not? | 20:38 |
| Muligan | So we acquired and ISP with multiple servers and a multitude of IP space. The various servers were within a /29, and that /29 was published within the /24 via the edge BGP routers. | 20:38 |
| Muligan | (2) of the server resources (DNS/NTP) needed to be split up between datacenters, but retain connectivity to that network's equipment | 20:39 |
| Muligan | without going through and changing thousands of config files, etc. | 20:39 |
| scottpedia | bro I am done here | 20:40 |
| Muligan | those servers were archaic, this our CORE DNS/NTP server were to be repurposed without spinning up a special set of VMs | 20:40 |
| Muligan | scottpedia, :D | 20:40 |
| scottpedia | can't do this without a diagram or something | 20:40 |
| * scottpedia 's brain just went haywire | 20:40 | |
| leftyfb | Muligan: you don't expect to public/routable retain ip space across multiple datacenters just by client-side network configs do you? | 20:40 |
| Muligan | anyhow, the network team stood up a pair of /32 routes targeting our CORE DNS/NTP servers. | 20:40 |
| * leftyfb sigh | 20:41 | |
| leftyfb | "/32 routes" | 20:41 |
| Muligan | yes, /32 routes | 20:41 |
| leftyfb | Muligan: you don't expect to retain public/routable ip space across multiple datacenters just by client-side network configs do you? | 20:41 |
| Muligan | allows you to push that singular IP to another subnet/target IP | 20:41 |
| Muligan | this isn't just client-side network configs happening | 20:41 |
| leftyfb | right, so your issue is beyond the client config/Ubuntu | 20:42 |
| Muligan | noooo | 20:42 |
| Muligan | the simple issue/question I was looking for is how to add a /32 'virtual interface' or even /32 IP to respond | 20:42 |
| Muligan | but with the default route already established, this is all taken care of now | 20:43 |
| leftyfb | ok, so all is well then | 20:43 |
| leftyfb | also, upgrade that OS. It's unsupported and insecure | 20:43 |
| scottpedia | leftyfb: zup man | 20:44 |
| Muligan | that I understand, and it's currently on our project board | 20:44 |
