[04:00] <arunpyasi> rbasak, interesting.. thanks ! :)
[07:09] <lordievader> Good morning
[07:47] <cpaelzer> hi lordievader, how are you this week?
[07:47] <lordievader> Doing okay so far. How are you cpaelzer ?
[07:53] <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
[07:54] <lordievader> 🙂
[10:08] <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?
[10:12] <rbasak> Takumo: some nodes in some paths block mtr's probes.
[10:13] <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
[10:21] <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
[10:25] <rbasak> Sounds like you have stuff blocking stuff.
[10:26] <rbasak> If tracepath does work, I'd start by running tcpdump/wireshark to see the difference and then try tweaking mtr settings to match.
[10:28] <Takumo> ah, found it
[10:28] <Takumo> TTL
[14:05] <daincredibleholg> Hi. Anyone here running Dovecot + Antispam + Spamassassin with pipe backend successfully?
[14:07] <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?
[16:02] <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.
[16:19] <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.
[17:32] <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
[17:33] <cyphermox> netcfg/get_hostname is also not followed
[17:42] <powersj> cyphermox: so this is a larger issue?
[17:48] <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
[17:49] <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
[18:00] <vpndude> Is there a ultra stripped down version of ubuntu server
[18:00] <vpndude> one that is hardened and small kinda like alpine
[18:42] <JanC> I think you would also need a stripped down kernel etc. for that?
[18:43] <sarnold> what would you strip? your 'needless module' is someone else's device in their boot chain :)
[18:44] <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
[18:55] <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
[18:56] <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
[18:57] <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
[18:58] <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
[18:59] <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
[19:00] <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
[19:08] <sdeziel> drab: I'd look into netsniff-ng
[19:08] <drab> nice, thanks, packet sniffing beast sounds good :)
[19:09] <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
[19:10] <drab> oooh zero-copy, nice
[19:49] <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 :)
[19:50] <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
[19:51] <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
[19:52] <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
[19:53] <drab> just in case anybody is interested, because afaik there's no ubuntu based small system out there that works and can be pxebooted
[19:54] <JanC> drab: I assume the minimal install ISO can be PXE-booted  :)
[19:55] <drab> JanC: only to install afaics, not for rescue
[19:55] <drab> ie it doesn't give you a full working system over pxe
[19:56] <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
[19:57] <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
[19:58] <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"
[19:59] <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
