| mojtaba | Hello, (It might not be related to this topic. It is more network based problem.) I have a raspberry pi which is connected to the router wirelessly, and I have a vpn client configured on it. My router is very old, and I cannot install a new firmware on it. I just wanted to know that if it could be possible to route all the chromecast traffic through raspberry pi? (Through VPN?) I can connect Chromcast to the raspberry pi, using a LAN cable. | 16:07 |
| TJ- | bindi: probably too late but if you're around here's a package of scripts that automate building and testing RAID-1 + LUKS + LVM in a virtual machine http://iam.tj/projects/ubuntu/raid1-luks-lvm-test.tar.gz | 16:12 |
| mojtaba | I have just deployed an Ubuntu machine, it shows '9 packages can be updated. 7 updates are security updates.' but when I run sudo apt-ge t update; sudo apt-get upgrade, nothing happens. Do you know what should I do? | 17:23 |
| mojtaba | When I log back in again, it shows me the same messages. | 17:23 |
| mojtaba | I have asked the same question in #ubuntu, but no I have received no response back. | 17:24 |
| mojtaba | TJ- respond me back in #Ubuntu. Thanks again. | 17:29 |
| lotuspsychje | fleabeard: place your details here fleabeard | 17:29 |
| fleabeard | hiya lotuspsychje: my issue is my Ethernet controller: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02) | 17:32 |
| fleabeard | is only running in 100 Mbps mode instead of 1000 Mbps mode. I'm currently using Ubuntu Server 18.04 LTS. | 17:32 |
| lotuspsychje | system up to date fleabeard ? | 17:32 |
| TJ- | fleabeard: show us "lspci -nnk -d::0200" | 17:32 |
| fleabeard | TJ-, https://pastebin.ubuntu.com/p/8KpRSVK67x/ | 17:33 |
| fleabeard | lotuspsychje, yes, updated this morning (fresh install) | 17:33 |
| lotuspsychje | allright tnx fleabeard | 17:33 |
| TJ- | fleabeard: and check what the link is advertising with "sudo ethtool <IF>" | 17:34 |
| TJ- | Compare the advertised, supported, and actual "Speed:" | 17:35 |
| fleabeard | TJ-, https://pastebin.ubuntu.com/p/vZYHN33qyR/ | 17:36 |
| TJ- | fleabeard: it has auto-negotiated with the switch, so either a poor connection somewhere (Gigabit needs all 8 cores working) or the switch doesn't agree :) | 17:37 |
| fleabeard | TJ-, thanks, I'm trying to confirm with the router I'm using (TP-Link Archer C9) that the ports are gigabit. | 17:37 |
| TJ- | fleabeard: "4 10/100/1000Mbps LAN Ports," | 17:40 |
| fleabeard | TJ-, thank you! my goodness I was having so much trouble verifying this for some reason! So I'm guessing all 4 ports support gigabit? | 17:41 |
| TJ- | yes, and the WAN port, according to https://www.tp-link.com/us/products/details/cat-5506_Archer-C9.html#specifications | 17:44 |
| TJ- | fleabeard: I'm finding a lot of reports from several years ago about this same symptom with that chipset, and its predecessor, affecting Windows, but I'd have thought it was resolved by now | 17:45 |
| TJ- | one person says, "unplug and replug after initial negotiation (of 100Mbps) sometimes fixes it" | 17:46 |
| cryptodan_mobile | fleabeard: what kind cable and how long? | 17:49 |
| fleabeard | TJ-, I'll give that a try then. | 17:50 |
| fleabeard | cryptodan_mobile, it's a hand-made cat6 cable about 5' long | 17:50 |
| Glorfindel | I've reinstalled libssl1.0.0 and libssl-dev, but I'm still getting errors about "error while loading shared libraries: libssl.so.1.1: cannot open shared object file: no such file or directory" | 17:51 |
| Glorfindel | what's the process to fix this? | 17:51 |
| cryptodan_mobile | fleabeard: if ya can go buy a premade 10foot one to see if it's your cable | 17:52 |
| fleabeard | TJ-, the unplug/re-plug trick didn't do the trick :( | 17:52 |
| fleabeard | cryptodan_mobile, I tried a purchased cat5e cable and had the same issue (which is why I created the cat6 cable last night) :) | 17:52 |
| cryptodan_mobile | Wow | 17:53 |
| Annoyed | Greetingws | 19:57 |
| Annoyed | Greetings, rather. | 19:57 |
| Annoyed | I've got a 14.04 LTS server that's been up and doing its job for 4 years now.. looking at rebuilding. I've seen that there seem to be a number of changes to networking in 18.04.1... And that some folks are having headaches with it... | 20:00 |
| Annoyed | is 18.04.1 stable enough to put in and expect to behave itself ? | 20:01 |
| TJ- | Annoyed: the issues are generally around converting ifupdown to netplan/systemd-networkd configs | 20:01 |
| TJ- | Annoyed: so really it's mostly more about the learning curve | 20:02 |
| TJ- | Annoyed: plus of course, for 14.04>18.04 the init system changes from upstart to systemd | 20:02 |
| Annoyed | That's one of my concerns. I've been using this thing as a router; 2 interfaces, configured in /etc/network/interfaces. In my setup, the inside interface doesn't need gateway or DNS info, it's the uplink for the inside network. But looking at setting up the file in /etc/netplan, everything I've read says you have to set a DG & DNS in that file... | 20:04 |
| Annoyed | I don't want to set amachine 2nd DG for this | 20:04 |
| Annoyed | err... I don't want to set a 2nd default gateway for this machine. | 20:05 |
| mybalzitch | netplan is junk, stick with ifupdown | 20:05 |
| Annoyed | Can you still use the old way ? | 20:05 |
| Annoyed | Or maybe just 16.04.5 instead? | 20:06 |
| mybalzitch | yes you can still do it the old way and maintain your /etc/network/interfaces file | 20:07 |
| Annoyed | I've set up VM's for both and I really don't like the look of netplan either.. Is there a howto or docs someplace on using 18.04 with the old setup? | 20:08 |
| TJ- | Annoyed: netplan interfaces don't need a default gateway setting | 20:08 |
| Annoyed | T3- So I can try to just set it up w/out that info in the yaml file? | 20:10 |
| Annoyed | The more I read on this, the more I think I'm better off installing 16.04.5 and wait for the dust to settle on this new crap.. I don't want to spend a lot of time figuring out netplan if it's a problem child. | 20:17 |
| TJ- | Annoyed: recall that netplan is designed to *generate a run-time config* - if the config is static then netplan isn't needed, you can directly create a systemd-networkd config | 20:26 |
| TJ- | Annoyed: the point of netplan was to support 'cloud' containerised devices via cloud-init but it seems to have leaked back to bare-metal/long-running 'traditional' servers | 20:26 |
| Annoyed | Outside interface is DHCP, but inside is static. | 20:27 |
| cryptodan_mobile | Netplan should only be on the cloud instance then | 20:27 |
| Annoyed | So how do I configure the inside interface? | 20:28 |
| TJ- | Annoyed: if you want to see a systemd-networkd config for a server with 2 logical interfaces (1 x VLAN, 1 x LACP bond) see http://iam.tj/projects/ubuntu/systemd-networkd-bonding.txt | 20:29 |
| TJ- | Annoyed: for your needs you'd only need 2 basic .network descriptions, 1 for static, and 1 for DHCP | 20:31 |
| Annoyed | I gather I can leave whatever the installer sets up for the outside interface, cause it seems to work, at least on the VM, but how do I set up the inside static? | 20:31 |
| Annoyed | \ /etc/systemd/network seems to be empty on my VM of 18.04 | 20:33 |
| TJ- | Annoyed: look at my "/etc/systemd/network/LAN_Aggregate.network" you'd just alter the "Name=bond0" to be the name of the LAN NIC | 20:33 |
| TJ- | Annoyed: yes, it will be, that is where the sysadmin puts the static config | 20:33 |
| TJ- | Annoyed: if a runtime config is being generated (by netplan) it'll be in /run/systemd/network/ | 20:34 |
| TJ- | Annoyed: and you can directly copy a file from there to /etc/systemd/network/ and remove the netplan config so netplan no longer generates a boot-time config under /run/ | 20:34 |
| Annoyed | Oh, so I create a devicename.network file in /etc/systemd/network, and treat that as /etc/network/interfaces? | 20:35 |
| TJ- | Annoyed: :D yup | 20:35 |
| Annoyed | Ok, that makes sense | 20:35 |
| TJ- | Annoyed: and remove any /etc/network/interfaces entries/file(s) so that the sysv ifupdown compatibility systemd units don't try to create an additional config! | 20:36 |
| Annoyed | This is gonna be a clean install | 20:36 |
| Annoyed | so there shouldn't be any | 20:36 |
| Annoyed | Hmmm is one, but it's all comments | 20:37 |
| TJ- | Right; with you mentioning the 14.04 I just wanted to be clear - we've seen people caught out by systemd playing nice with the existing ifupdown config and the sysadm also creating a systemd config, and the 2 clashing | 20:37 |
| Annoyed | Ok, thanks | 20:38 |
| Annoyed | That makes sense | 20:40 |
| Annoyed | Thanks for the help. Much appreciated | 20:43 |
| bindi | TJ-: currently rocking Debian on the machine :D | 21:48 |
| TJ- | bindi: I've been updating the scripts, and you can now see an ascii-cast of it at work: http://iam.tj/projects/raid-vm/ | 21:49 |
| TJ- | bindi: I've been playing with it in the VM, detaching disks etc. It boots perfectly degraded without me even realising :D | 21:50 |
| bindi | nice | 21:51 |
| TJ- | I integrated the LUKS unlocking into the initrd.img so the passphrase only needs typing once, for GRUB | 22:05 |
