| lordievader | Good morning | 07:09 |
| cpaelzer | hi lordievader, how are you this week? | 07:47 |
| lordievader | Doing okay so far. How are you cpaelzer ? | 07:47 |
| cpaelzer | nacc: no it was not about the iscsi in xenial I know that we killed it there | 07:53 |
| cpaelzer | nacc: instead it was the one in trusty by a new HWE form Xenial that exceeds two digit version numbers | 07:53 |
| cpaelzer | lordievader: ok as well over here | 07:53 |
| lordievader | 🙂 | 07:54 |
| Takumo | HI all, I'm having issues with `mtr`, its only showing 7 hops, but tracepath is going to 30 before giving up | 10:08 |
| Takumo | Any ideas why? | 10:08 |
| rbasak | Takumo: some nodes in some paths block mtr's probes. | 10:12 |
| Takumo | rbasak: does mtr not default to using the same ICMP probes as tracepath? | 10:13 |
| rbasak | I'm not sure. | 10:13 |
| rbasak | Looks like it uses ICMP echoes by default, but there are options to change that. | 10:13 |
| rbasak | eg. --tcp | 10:13 |
| Takumo | yeah, that gives me a whole bunch of different addresses for hop 6 , but still only 7 hops, 6 being the only one that replies | 10:21 |
| rbasak | Sounds like you have stuff blocking stuff. | 10:25 |
| rbasak | If tracepath does work, I'd start by running tcpdump/wireshark to see the difference and then try tweaking mtr settings to match. | 10:26 |
| Takumo | ah, found it | 10:28 |

| daincredibleholg | Hi. Anyone here running Dovecot + Antispam + Spamassassin with pipe backend successfully? | 14:05 |
| daincredibleholg | I try running it on Ubuntu Server 16.04 and it looks like the plugin is doing exactly nothing. I can see its configuration being loaded with every IMAP interaction, but it is not doing anything. I added some logger and file touches in the wrapper script and also tried the spool2dir backend, which should write the mails-to-be-relearned to a folder. Nothing happens. No error messages and enabling debug just shows me that it is loading the | 14:07 |
| daincredibleholg | config. | 14:07 |
| daincredibleholg | Ideas? | 14:07 |

| wad | Hey guys. I've got a 14.04 LTS 64-bit desktop-edition server running in the cloud, running postfix and spamassassin. Recently started getting this error: /etc/cron.daily/spamassassin: | 16:02 |
| wad | invoke-rc.d: initscript spamassassin, action "reload" failed. | 16:02 |
| wad | Anyone running a similar configuration, seen this issue? Some googling showed me a few things, nothing really useful. I'm just checking here first, before I dive headfirst into the weeds on it. | 16:02 |
| powersj | cyphermox: Any further thoughts on: LP: #1732776? As far as testing, I'm tempted to change our automated tests to use priority to get things going. | 16:19 |

| cyphermox | powersj: +1, priority will work for now and we'll fix the rest, clearly something was wrong seeing from my debugging session with infinity on friday evening | 17:32 |
| cyphermox | netcfg/get_hostname is also not followed | 17:33 |
| powersj | cyphermox: so this is a larger issue? | 17:42 |
| cyphermox | same issue for both, something is going wrong in the migration of the preseed keys from the kernel command-line to the installer's environment | 17:48 |
| cyphermox | so, I'm a bit surprised that priority alone works, but that might just be because multiple things go parse stuff in the command-line, and when you deal with aliases it gets a bit more complicated | 17:49 |
| vpndude | Is there a ultra stripped down version of ubuntu server | 18:00 |
| vpndude | one that is hardened and small kinda like alpine | 18:00 |
| JanC | I think you would also need a stripped down kernel etc. for that? | 18:42 |
| sarnold | what would you strip? your 'needless module' is someone else's device in their boot chain :) | 18:43 |
| mgolisch | hm if landscape-client fails to register with a 404 error what did i do wrong? | 18:44 |
| mgolisch | i used the command it displays on the landscape computers page | 18:44 |
| drab | hi, anybody doing something like ntop? I'm trying to figure out if and how I can setup a pcap ring buffer and generate some stats from it on the fly | 18:55 |
| drab | for now analyzing 1Gbps | 18:55 |
| drab | I think ntop does thing, with their PF_RING thingie | 18:56 |
| drab | basically do a pcap capture to ram in a ringbuffer fashion and analyze it before it gets overwritten or something | 18:56 |
| drab | the alternative, maybe simpler, would be to setup tpcudmp doing ring pcap writes and then have another process parse the last written pcap, maybe use a ramdisk for that | 18:57 |
| drab | closest thing I could find is this, which actually kind of fit the bill: https://github.com/kumina/promacct | 18:58 |
| drab | but my c++ sucks | 18:58 |
| drab | the problem with pmacct is that it just does accounting, ie you can't do flow reconstruction and extract say a url from the pcap | 18:59 |
| drab | which is also why netflow/sflow isn't a good chioce, altho I will prolly use that for a more lightweight accounting system with pmacct | 19:00 |
| sdeziel | drab: I'd look into netsniff-ng | 19:08 |
| drab | nice, thanks, packet sniffing beast sounds good :) | 19:08 |
| drab | speaking of stuff with horns... I also found this from bsd that is packaged for ubuntu: https://github.com/Cisco-Talos/Daemonlogger | 19:09 |
| drab | basically a soft tap, which is nice | 19:09 |
| drab | oooh zero-copy, nice | 19:10 |
| JanC | sarnold: they want their whole base system to be the size of what the Ubuntu kernel is now, so that's obviously not possible with a default Ubuntu kernel :) | 19:49 |
| sarnold | JanC: ha :) | 19:49 |
| JanC | those are also often used as container-only distros, so many devices wouldn't be relevant | 19:50 |
| sarnold | so then they just want lxd 'images' or something | 19:50 |
| JanC | you would have to ask that "vpndude" what they want | 19:50 |
| JanC | container/vm (not sure what they want) | 19:51 |
| * drab just built the smallest possible pxe bootable system for rescue | 19:51 | |
| drab | well, not true, but pretty small | 19:51 |
| drab | I guess I could strip all the binaries and remove a bunch fo modules that i'm unlikely to use, but it's the smallest I could make while supporting all the modern hw | 19:52 |
| drab | heck of a weekend, thanks to TJ- or I wouldn't have made it | 19:52 |
| drab | just in case anybody is interested, because afaik there's no ubuntu based small system out there that works and can be pxebooted | 19:53 |
| JanC | drab: I assume the minimal install ISO can be PXE-booted :) | 19:54 |
| drab | JanC: only to install afaics, not for rescue | 19:55 |
| drab | ie it doesn't give you a full working system over pxe | 19:55 |
| JanC | it should be possible to drop to a shell IIRC, but it might not be very useful | 19:56 |
| drab | some ppl are ok/happy with just getting busybox going that way and hitting alt-2, but that's not my case | 19:56 |
| drab | right, that, not enough, I want an actual mini iso booted, basically a server system so that I can run a bunch of tools for diagnostic etc, kinda like UBCD | 19:56 |
| drab | except that after trying UBCD kinda sucks ime and is not apt based/can't add tools at runtime like that | 19:57 |
| drab | same for systemrescueCD | 19:57 |
| JanC | sort of like the rescue system some hosting providers have... | 19:57 |
| drab | rootfs is 80MB, about 40MB of initrd | 19:57 |
| drab | I guess, yeah | 19:57 |
| drab | this is a full system tho, you can't tell the diff with say booting ubuntu server of an installed machine | 19:57 |
| drab | it's no strippped down other than for what comes preinstalled with it | 19:57 |
| drab | and the other requirements was to boot over http, withou the nfsroot stuff | 19:58 |
| drab | which otherwise makes it possible to boot an install CD and "try before install" | 19:58 |
| drab | the only thing I couldn't fix was dns in busybox... had to use ips in the pxe menu entry | 19:59 |
| JanC | e.g. https://wiki.hetzner.de/index.php/Hetzner_Rescue-System/en | 19:59 |
| drab | but apart from that I'm pretty happy with the result and I have a whole new appreciation for ramdisks... with a local apt mirror I can convert into a full desktop if needed in 10sec | 19:59 |
