| Kason | why would my system tell me it can't find the cd command when I try to use it with sudo? | 08:50 |
|---|---|---|
| sigv | Kason: `cd` is a built-in command of the shell you are using. executing `cd` as a separate command on its own does not provide any benefit for you outside of your shell's context. | 08:52 |
| Kason | sigv: ok. that's interesting. had never encountered a situation where it had come up before | 08:53 |
| Kason | I can cd in to /etc but get '-bash: cd: /etc/wireguard: Permission denied' when I try to go into one of its directories | 08:57 |
| TJ- | Kason: you need to use an interactive 'sudo' session as 'root' with "sudo -i" | 09:01 |
| twb | Kason: "sudoedit /etc/wireguard/wg-DPRK.conf" | 09:02 |
| Kason | thanks guys | 09:11 |

| raddy | Hello | 12:10 |
| raddy | I am running Ubuntu 20-04 and I have enabled PasswordAuthentication no and ChallengeResponseAuthentication no and have restarted ssh as well | 12:10 |
| raddy | But still password is being asked | 12:10 |
| raddy | Password authentication is default | 12:10 |
| ogra | raddy, AuthenticationMethods publickey | 12:26 |
| ogra | (and make sure the pub key is on the server and secret key on the client indeed) | 12:26 |
| raddy | Hello | 13:40 |
| raddy | I need your help | 13:40 |
| raddy | I configured a new ubuntu 20,04 server and everything was well and fine | 13:41 |
| raddy | I rebooted it to apply update, since then ssh login is damn slow | 13:41 |
| twb | raddy: it is probably DNS | 13:44 |
| raddy | twb: No, stuck at stuck Successfully set console input code page | 13:47 |
| twb | raddy: SSH does not have "code pages" | 13:49 |
| twb | Can you describe your symptoms more? | 13:49 |
| raddy | twb: key pair authentication. password login disabled, login successful, take about 10 minutes to login, | 13:52 |
| twb | Tell us exactly and in full detail: full information about the inputs; what you typed/clicked/did; what you saw, and what you expected to see | 13:53 |
| raddy | I think, I have found the issue. | 13:53 |
| raddy | twb: Failed to retrieve unit state: Connection timed out | 13:55 |
| raddy | twb: when trying to restart sshd | 13:55 |
| twb | So you ran "sudo systemctl restart ssh" ? | 13:56 |
| raddy | service sshd restart and I know the command is correct | 13:56 |
| twb | What is the output of "systemctl status ssh"? | 13:57 |
| raddy | client ssh is running in -vvv for your information | 13:57 |
| raddy | all commands are slow | 13:58 |
| raddy | I think there may be a problem in loop back device or hosts file | 13:59 |
| raddy | twb: Can you give hints ? | 14:00 |
| twb | What is the output of "systemctl status ssh"? | 14:00 |
| raddy | Failed to get properties: Connection timed out | 14:00 |
| twb | OK | 14:00 |
| twb | That sounds like maybe dbus is broken | 14:01 |
| twb | Let's check for basic resource exhaustion. | 14:01 |
| twb | What is the output of "free -h"? | 14:01 |
| raddy | Mem: 31Gi 659Mi 27Gi 1.0Mi 2.7Gi 30Gi | 14:02 |
| twb | OK that is fine. What is the output of "df -h" | 14:02 |
| raddy | 3.5TB free | 14:03 |
| raddy | in / | 14:03 |
| twb | *all* fliesystems are less than 80% full? | 14:03 |
| raddy | except loop back devices, yes | 14:03 |
| twb | The loopback filesystem is a squashfs? | 14:04 |
| raddy | How to find that | 14:04 |
| twb | "mount" (with no arguments) | 14:04 |
| raddy | tmpfs shm | 14:04 |
| twb | If shm is 100% full your system is broken | 14:05 |
| raddy | that's is not full, | 14:06 |
| raddy | 0% | 14:06 |
| twb | Then I do not understand you | 14:06 |
| twb | Do you know how to use a pastebin? | 14:06 |
| raddy | Absolutely | 14:06 |
| twb | please pastebin full output each time, then | 14:07 |
| raddy | Which command ? | 14:07 |
| raddy | All auth is slow | 14:07 |
| raddy | not commands | 14:08 |
| twb | run "sudo -i" to become root and stay root | 14:08 |
| raddy | Yeah, I became root after quite a long time of waiting | 14:09 |

| dwigton | Can a NIC be setup as a trunk with no untagged traffic? I am attempting to put LXC containers on different vlans but am not sure how to to tag the default interface such that I can still ssh into the server. | 19:23 |
| === ijohnson|lunch is now known as ijohnson | ||
| RoyK | dwigton: just named the default interface eth0.1 and it should tag vlan1 | 19:26 |
| RoyK | then don't use eth0 | 19:27 |
| RoyK | replace names to whatever your nic is called | 19:27 |
| dwigton | Ah, the naming scheme matters? | 19:27 |
| RoyK | the dot <n> means vlan <n> | 19:28 |
| RoyK | it's that simple | 19:29 |
| dwigton | But does the first part need to be eth0? or enp0s25 in my case? | 19:30 |
| RoyK | enp0s25.VLANID | 19:33 |
| dwigton | Ok, thanks, I had set it up using cloud-init and it seemed like I could name them whatever I wanted since the config file defines the vlanid and parent interface. | 19:35 |
| teward | dwigton: unless you've done some trickery with cloud-init and netplan match blocks to define special names for your interfaces, it'll be whatever they are as detected - such as `enp0s25`. If your interface is `eth0` then it's eth0, if it's enp0s25 it's enp0s25. If I have match trickery on Netplan to make my interface named 'internet' then technically it'd be 'internet' at the beginning. But that's some chaotic level stuff. | 19:41 |
| teward | dwigton: so unless you've provided a name other than enp0s25 you need to use the interface name. | 19:41 |
| teward | TECHNICALLY in cloud-init you can preconfigure it to be any 'name' but if the first part doesn't match an interface nothing gets configged. | 19:42 |
| nikolaj_basher | On my server where i running af web app I use smtp office365 to send email from. But somehow it ends up in the receivers spam. Is there some how I can bugfind why I have set up and spf record on the mail domain but I send it from a sub domain, du I need to include the subdomain in the dns record? | 20:43 |
| nikolaj_basher | or is there a better channel to get some help?? | 20:51 |
| tomreyn | i doubt there's a channel dedicated to the office365 smtp service or an email deliverability channel. you could reviewing microsofts' documentation on their service. | 21:06 |
| tomreyn | *try | 21:07 |
| tomreyn | unless you're running a mails erver on ubuntu and have trouble sending mail from there, it's hardly an ubuntu topic | 21:07 |
