| JanC | and parted packages are on the Ubuntu 5.04 Server CD image (but not installed in the live session used by the installer) | 00:01 |
|---|---|---|
| xedniv | JanC: so how do you get them on the live session? you keep trying to undo your claim that i was stating false information, whereas the issue is very simple: no, there are no usable parted binaries in the CD. i dont care if inside the dpkg seeds there is one package for it. | 00:05 |
| xedniv | theres probably apache too somewhere in the seed repo for the initial install, so what? | 00:05 |
| xedniv | the toolchain in 15.04 is broken to no avail for building fPIC libs, so cannot build a static parted here right now | 00:06 |
| xedniv | may need to setup a gentoo vm for that | 00:06 |
| JanC | well, there is partman on the live image, why doesn't that work? | 00:07 |
| xedniv | ugh | 00:08 |
| xedniv | partman is terrible. ill seeif i can get around its limitations before i have access to a host that can build proper static execs of parted | 00:08 |
| xedniv | i also need to script this installation so it can be done remotely | 00:08 |
| JanC | I'm sure you can install the parted udeb if you really want it | 00:11 |
| xedniv | https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/640734 | 00:12 |
| ubottu | Launchpad bug 640734 in gcc-4.4 (Ubuntu) "crtbeginT.o needs to be recompiled with -fPIC" [Undecided,Confirmed] | 00:12 |
| xedniv | JanC: can you tell me how that works? | 00:12 |
| xedniv | btw that is a blocking bug for anyone compiling static execs | 00:12 |
| JanC | xedniv: udpkg -i /cdrom/pool/main/p/parted/parted-udeb<tab> | 00:30 |
| JanC | I tried using partman to set up an encrypted volume on lvm and that seemed to work fine too BTW | 00:32 |
| xedniv | JanC: describe encrypted volume | 00:35 |
| xedniv | did it contain a single partition or multiple? | 00:35 |
| xedniv | ex. /boot, LVM(/, /etc, /var, /home, ...) | 00:36 |
| JanC | well, this was just a quick VM experiment, so I only tried unencrypted /boot + LVM+encrypted / | 00:37 |
| JanC | but, as said, you can install udebs with udpkg :) | 00:38 |
| xedniv | yeah, LVM with SINGLE partition is easy with partman | 00:45 |
| xedniv | otherwise it has never worked well for me | 00:45 |

| lordievader | Can you pastebin the output of 'ip r'? | 08:13 |
| Neo9 | lordievader: ip r ..? would you reveal the command. | 08:14 |
| _ruben | that is the command | 08:14 |

| lordievader | On either 198.20.108.115 or 198.20.108.114 | 08:20 |
| Neo9 | lordievader: let me check | 08:22 |
| Neo9 | lordievader: and point1: i am able to ping the 198.20.90.115 from outside. but from 115 to 114 or any other is not working. | 08:23 |
| lordievader | Neo9: Uhuh, I get the feeling arp is broken. | 08:23 |
| lordievader | Hence the tcpdump to verify. | 08:23 |
| Neo9 | lordievader: it is installed in 114 | 08:24 |
| lordievader | Neo9: Good, run 'sudo tcpdump -i any arp' then try to ping .114 from .115. Do you see any arp request incomming from the .115? | 08:25 |
| Neo9 | lordievader: http://pastebin.com/A7SYeXDa | 08:29 |
| lordievader | No responses? There is your problem. | 08:30 |
| lordievader | .114 cannot send a ping to .115 because it doesn't know it's mac address. | 08:30 |
| lordievader | Now I am interested if .115 never receives the arp request or that .115 refuses to answer. | 08:31 |
| Neo9 | lordievader: understood, but how can i resolve it? | 08:32 |
| lordievader | Neo9: First try and answer the question I just asked ;) | 08:33 |
| Neo9 | lordievader: not understood what exactly you asking? it saying that "destination is unreachable" | 08:37 |
| === cipi is now known as CiPi | ||
| lordievader | Neo9: Does .115 receive the arp request? | 08:38 |
| Neo9 | lordievader: how can i know that? i am able to ping .115 from .114 but not vice versa. | 08:40 |
| Neo9 | lordievader: can i know how to check that? | 08:40 |
| lordievader | Neo9: Run 'sudo tcpdump -i any arp' on .115 then ping from .114. | 08:40 |
| Neo9 | lordievader: oops; tcpdump is not installed in the .115. And since even ping 8.8.8.8 not works, it is not possible to install it now. | 08:42 |
| lordievader | Hmm, I am mixing things up. Anyways I get the idea that your broadcast channel is wrong. | 08:44 |
| Neo9 | lordievader: might be. then how it's worked for me earlier? | 08:44 |
| lordievader | I have no idea, what has changed since then? | 08:46 |
| Neo9 | lordievader: is there any issue with mac address? And how can i read MAC address of other machine with arp? | 08:47 |
| lordievader | What arp does is shout in the broadcast channel who has ip X, if a machine holds ip X it responds through unicast that it has ip X. however that reply is never received by your problem machine. | 08:48 |
| lordievader | So either the problem is, no other machines receive the arp requests, or they refuse to send the reply. | 08:49 |

| skittishtrigger | I am doing my first major server transfer(from one host to another)I would love to be able to do some type of image deal and transfer the whole thing at once so I can shut down one server and update the other and take off. Is this possible with Ubuntu and not having physical access? | 15:26 |
| TJ- | skittishtrigger: depends on whether transferring bare-metal or VM, and if VM, what hypervisor source and destination use. Also, after transfer, things like network might need reconfiguring (different MAC address, different device naming, etc) | 15:28 |
| skittishtrigger | It would be baremetal. I have not progressed to doing vm's yet | 15:29 |
| skittishtrigger | Its a fairly simple server with a webserver and several game servers, quassel, etc. | 15:29 |
| skittishtrigger | I was thinking with the custom config on a lot of things if it might be a better route to just make a list usable by ubuntu with everything that is installed on it and use that then re-set up everything? | 15:31 |
| TJ- | skittishtrigger: so main difference will be hardware, and most drivers should auto-detect and load. Anything tied to NIC MACs will fail though... so think of /etc/udev/rules.d/70-persistent-net.rules | 15:32 |
| TJ- | skittishtrigger: you could. debfoster is a useful too for creating the dependency list | 15:33 |
| skittishtrigger | ok, I will google that and look into it. luckily the only think network wise that is coded in is just the ips for client connections | 15:34 |

| TJ- | Synopsis: As I said earlier, edit the init system's ttyX configuration so it does "exec /sbin/getty -8 -a <$USER> 38400 tty6" | 16:53 |
| TJ- | Synopsis: precise syntax depends on which init system it is | 16:53 |
| TJ- | Synopsis: my example above is from a test I did on tty6 with upstart's /etc/init/tty6.conf | 16:53 |
| Synopsis | and as I told you earlier, those files don't exist for me | 16:57 |
| TJ- | Synopsis: So find out where systemd stores it's equivalent, which are called unit files | 16:58 |
| TJ- | Synopsis: "man systemd-units" should give all the details required to find them | 17:00 |
| Synopsis | ty, will look | 17:01 |
| TJ- | Synopsis: "dpkg -L systemd" will list all the files the systemd package installs | 17:01 |
| TJ- | Synopsis: "dpkg -L systemd | grep getty" should narrow down your search | 17:02 |
| Synopsis | the grep line returned a few files | 17:04 |
| Synopsis | http://pastebin.com/csM3rN4H | 17:07 |
| Synopsis | and btw, when i try to man systemd-units, i get no man entry | 17:08 |
| TJ- | Synopsis: ahhh, no S. "man systemd.unit" | 17:09 |
| Synopsis | same thing, no man entry | 17:09 |
| Synopsis | i get one for just systemd | 17:10 |
| TJ- | Synopsis: I've not the systemd source-code here. It looks as if units/getty@service is what you want, it has a line "ExecStart=-/sbin/agetty --noclear %I 38400 linux" which is, I suspect, the one that needs editing to include "-a <username>" | 17:10 |
| TJ- | Synopsis: that is 15.04, right? | 17:10 |
| Synopsis | yes, 15.04 | 17:11 |
| TJ- | Synopsis: according to packages.ubuntu.com that file is installed (as /usr/share/man/man5/systemd.unit.5.gz) | 17:11 |
| Synopsis | a zip file? i'll have to extract it, modify it, rezip it and replace? | 17:12 |
| TJ- | Synopsis: No... all man-pages are compressed to save space. They are uncompressed on the fly by the 'man' tool | 17:12 |
| TJ- | Synopsis: there's an ArchLinux guide on how to configure systemd for auto-login. https://wiki.archlinux.org/index.php/Automatic_login_to_virtual_console | 17:13 |
| TJ- | Synopsis: that shows creating an over-ride to the package-installed unit file, which is the preferred way to do this kind of config change (we never want to change a package-installed file - that may prevent the package being upgraded later) | 17:14 |
| Synopsis | k, knocking some stuff out @ work real quick and i'll give that a try | 17:15 |
| TJ- | Synopsis: For the man-page you've been typing a hyphen, not a full-stop. | 17:21 |
| Synopsis | i copied and pasted what you typed the first time, and then just backspaced the s off when you corrected yourself, didnt notice you also changed the - to a . | 17:23 |
| TJ- | Synopsis: Sorry... that first command I took directly from a web-page of the man-page, and the distro there seems to replace the full-stop with a hyphen | 17:24 |
| Synopsis | no need to apologize :) you're still being very helpful | 17:27 |
| TJ- | Synopsis: it's an intriguing option. Quite easy to implement once you find the correct file ;) | 17:28 |
| Synopsis | easy if you know what you're doing maybe...i ran the "systemctl edit getty@tty1" like on that link and copied the text into the file, rebooted and the system is hung at a blank screen with a blinking cursor | 17:29 |
| Synopsis | i can still ssh to it though | 17:29 |
| TJ- | Synopsis: Best to test on something other than the primary tty, that is generally reserved for system | 17:29 |
| Synopsis | ok, so how do i undo what I did and which tty should i use? any # but 1? | 17:30 |
| TJ- | Move that file to be @tty2, reboot, you should have a login prompt on tty1, and pressing Alt+F2 should get you onto tty2 | 17:30 |
| TJ- | You'll probably need to edit its contents too, if they mention 'tty1' of course | 17:31 |
| Synopsis | k, moved that file, rebooted, have my login prompt again, but it didn't auto login, and if i alt-f2, it's stuck at the blinking cursor...i've got to just be missing something stupid | 17:34 |
| TJ- | Synopsis: I see a possible confusion in those ArchLinux notes. They specify the file to manually edit inside the coloured code block that also shows the contents to use. *don't* include that filename in the file | 17:34 |
| TJ- | Synopsis: in other words, the content you add starts with the "[Service]" line | 17:35 |
| TJ- | Synopsis: just to be sure that systemd is creating the expected ttys... does Alt+F3 get you to a login on tty3? | 17:35 |
| Synopsis | yes, and i didnt copy the filename into the contents, just the [service] and below | 17:36 |
| TJ- | Synopsis: I'm not sure than; the fact you don't get a login prompt on tty2 shows the unit file is being acted on... presumably something fails, so no process takes on tty2 | 17:37 |
| Synopsis | would it be logged somewhere so I could get an idea? | 17:38 |
| TJ- | I think so, systemd is supposed to be quite verbose. I think "journalctl --unit=getty@tty2" *may* be what you need | 17:42 |
| Synopsis | nah...didnt return anything | 17:43 |
| TJ- | Synopsis: I may have the syntax wrong; I was trying to decipher the man-page | 17:43 |
| Synopsis | i ran it without any parameters and found this | 17:44 |
| Synopsis | at the very end | 17:44 |
| TJ- | try it for --unit=getty@tty1 .... if that shows something, at least we know its the correct syntax | 17:44 |
| Synopsis | nevermind, thats just the command i entered before that returned nothing | 17:44 |
| TJ- | You know you can directly paste text from a console? if you use "pastebinit <( your-commands-nere )" the output will be sent to a pastebin and you'll be given the URL to pass on | 17:45 |
| Synopsis | didnt know that :) | 17:45 |
| TJ- | or to send a plain file, "pastebinit /path/to/file" | 17:45 |
| TJ- | We use that extensively for support, provided the PC has an internet connection | 17:46 |
| Synopsis | @tty1 did return 2 lines | 17:46 |
| TJ- | Synopsis: OK ... try it for --unit=getty@tty3 as well . If that also returns something we know what we should be expecting for tty2 | 17:46 |
| Synopsis | nothing for 3 | 17:47 |
| TJ- | Synopsis: And there's a login on tty3 (Alt+3) ? | 17:47 |
| Synopsis | yes | 17:47 |
| TJ- | Synopsis: OK, that tells us tty1 is 'special' :) | 17:47 |
| TJ- | Synopsis: ok, "systemctl --failed" | 17:48 |
| Synopsis | what am i doing wrong here? | 17:49 |
| Synopsis | picturesadmin@localhost:~$ pastebinit <journalctl --unit=getty@tty1 | 17:49 |
| Synopsis | -bash: journalctl: No such file or directory | 17:49 |
| Synopsis | unrecogonized option --failed | 17:50 |
| Synopsis | oops | 17:50 |
| Synopsis | sorry, wrong base command | 17:50 |
| TJ- | Synopsis: "pastebinit <( command )" ... notice the parenthesis () immediately after the < | 17:51 |
| Synopsis | ok, didnt realize those were literal | 17:51 |
| TJ- | Synopsis: when I type commands inside double-quotes it shows exactly what is required, with the exception of the user-variable 'command' | 17:52 |
| Synopsis | http://paste.ubuntu.com/12142767/ | 17:52 |
| TJ- | Synopsis: OK, that confirms the unit failed, so we know it tried. Now lets get detailed info on the failure: "systemctl status getty@tty2 | tee /dev/stdout | pastebinit" | 17:54 |
| TJ- | Synopsis: that command lets you see the output as well as sending it to pastebin | 17:54 |
| Synopsis | http://paste.ubuntu.com/12142782/ | 17:54 |
| Synopsis | all it did was give me the pastebin url, didnt see output on screen | 17:55 |
| TJ- | Synopsis: oh... silly me, typos again ... should have had in there " | tee /dev/stderr | " | 17:57 |
| Synopsis | k...that showed me the output :) | 18:00 |
| TJ- | Synopsis: I think the cause is ArchLinux buts agetty in a different place to Ubuntu. I also notice that ExecStart= doesn't seem to be followed immediately by a hyphen as is shown in the ArchLinux guide - not sure if it is 100% vital but doubt it'd be there if it isn't needed. The correct path is ExecStart=-/sbin/agetty ... | 18:00 |
| TJ- | s/buts/puts/ | 18:01 |
| Synopsis | so run systemctl edit getty@tty2 and fix that path? | 18:03 |
| TJ- | Synopsis: Yes | 18:05 |
| TJ- | Then you should be able to test it immediately with "systemctl start getty@tty2" - no reboot required | 18:06 |
| Synopsis | ok, that worked, when i switched to tty2 it logged the user in, but i think i want it on tty1 since i want that to start my "slideshow" | 18:06 |
| TJ- | Synopsis: I think it would be better to keep tty1 reserved for the system since it is 'special' and just have a script/command the makes tty2 the active VT | 18:08 |
| Synopsis | i'm ok with that if you can point me in the direction to make it happen | 18:08 |
| * TJ- groans :D | 18:10 | |
| TJ- | I really walked into that! | 18:10 |
| Synopsis | hehe | 18:10 |
| TJ- | The manual command is "chvt X" where X would be 2 (like pressing Alt+F2). I need to check if there's another/better way to set it from boot | 18:13 |
