| theborger | anyone know a reason that BCM5709 would not work when doing an install? | 01:38 |

| mTeK | I'm trying to test a zfs pool write speed and dd keeps telling me that "dd: failed to open" the path to the zpool | 03:11 |
| mTeK | I can touch a file in the directory so why wouldn't dd be able to write there? | 03:12 |
| mTeK | "oflag=direct" removing that fixes the issue. | 03:15 |
| mTeK | Must be a zfs thing according to google. | 03:16 |

| jge | if I have a bond0 interface with lacp on, would I see those lacp messages being sent out with tcpdump? | 04:05 |
| M^tt | Good day, I've just started playing with uvtool and cloud images. I'm wondering where the hostname is set? as it seems to reset on each boot | 13:55 |
| M^tt | ok so its the datasource disk, i can see it has been pulled out into /run/cloud-init/instance-data.json, just not sure what format that disk is in ? best way to adjust it ? | 14:10 |
| M^tt | nevermind i guess im just mixing up hostname vs fqdn, it strips out the domain | 14:18 |
| M^tt | really should be able to set that fqdn though i think | 14:23 |
| hallyn | omg the 'new' ubuntu server install is annoying (over a slow remote console) | 16:51 |
| lotuspsychje | hallyn: new as in wich version? | 17:08 |
| hallyn | it's bionic | 17:16 |
| hallyn | was trying to do 'manual' disk setup | 17:16 |
| hallyn | near as i can tell, every time i go down a field, after 1s it times out and goes back to the top, and there are no shortcuts for 'back' (to reread bc i set it up in a shell) or 'done' | 17:17 |
| pennTeller | Hi guys, can I get your input on how to find the latest network outage on my ubuntu server? | 19:47 |
| TJ- | pennTeller: what kind of outage? | 19:54 |
| pennTeller | TJ- my website was down for a few minutes a couple of days ago and I woud like to find out why | 19:55 |
| pennTeller | TJ- so at the moment it was either my ubunt server failed somehow or my router was blocking visitors | 19:55 |
| pennTeller | so I am tying to find from the logs if the network was marked as having gone down | 19:56 |
| TJ- | pennTeller: well, start with the web-server logs, it may be the web server restarted. If not, then look at the kernel log, or various logs via journalctl | 19:56 |
| TJ- | pennTeller: for a hard loss of ethernet link, check the kernel log ("journalctl -b 0 -k") | 19:56 |
| pennTeller | TJ- thanks, I agree. I just don't know what I should be "grepping" for | 19:57 |
| pennTeller | thanks for that suggestion | 19:57 |
| TJ- | pennTeller: if you know the approx time it happened try using a timestamp to narrow it down | 19:57 |
| pennTeller | thank you, do you know any particular "greppable" termns? | 19:58 |
| TJ- | pennTeller: you can do things like "journalctl -b 0 --since 2 days ago' --until '1 day ago' " | 19:58 |
| TJ- | pennTeller: you can use exact dates/times in those expressions | 19:59 |
| pennTeller | thanks I will give that a show | 19:59 |
| TJ- | pennTeller: is systemd-networkd used to manage the network? if so "journalctl -b 0 -u systemd-networkd" may help | 19:59 |
| SuperLag | I understand it's considered good practice to not leave SSH Host keys on servers you intend for use with cloning. So you delete them. | 20:00 |
| SuperLag | However, I mistakenly assumed that Ubuntu Server would *automatically* generate new host keys when SSHD starts on boot. It does not. You're left with a machine you cannot log into remotely. Is this intended behavior? | 20:01 |
| SuperLag | RHEL and CentOS generate the new host keys, automatically, the next time sshd gets restarted | 20:02 |
| SuperLag | I logged in from the hypervisor console and ran "dpkg-reconfigure openssh-server" and this was the resolution. However, that seems like it shouldn't be necessary. Am I mistaken? | 20:04 |
| TJ- | SuperLag: that's the way it's done, from openssh-server.postinst script. I'm not aware of any boot-time detection/tooling to do that | 20:05 |
| SuperLag | TJ-: So if you're prepping a VM for cloning...what is your recourse? | 20:09 |
| SuperLag | the idea being you don't have a bunch of VMs with the same host key.. | 20:09 |
| TJ- | SuperLag: cloud-init | 20:10 |
| TJ- | SuperLag: see e.g. https://github.com/canonical/cloud-init/blob/master/doc/examples/cloud-config-ssh-keys.txt | 20:11 |
