drabanybody has a working installation of influxdb + snmp reporting from switches on an ubuntu server? does it work?00:36
drabI've seen some howtos here and there but nothing entirely coherent and I'm wondering if there are any specific gotchas I should be aware of00:37

dpb1drab: for the influxdb piece, yes: https://jujucharms.com/influxdb/4 it works well -- for feeding snmp data into it, I haven't used it for that, but that would be just an application of it, my google search would be as good as yours.05:27

Tobias92The recent update of Postfix to version 3.1.0-3 (last Wednesday) removed /usr/lib/postfix/dict_tcp.so. This is not documented in the changelog, and my mailserver needs this module to interact with postsrsd. Are TCP maps now built in? I don't want to risk outage by restarting the daemon... (I was redirected here from #ubuntu)08:41
rbasakTobias92: which package version exactly? 3.1.0-3 was published in the Trusty release pocket on 2016-04-13, so there's no recent update there.08:44
Tobias92rbasak, 3.1.0-3ubuntu0.1 according to apt-cache policy08:45
rbasakThere have been other updates, which is why you need to tell us the exact version08:45
rbasakOK08:45
rbasakTobias92: it looks like dict_tcp.so shipped in the postfix in Trusty, but has never shipped in the postfix in Xenial AFAICT.08:48
Tobias92Ah, I see, so the one I had must have been left over.08:49
rbasakSo it seems to me that nothing has changed around this in the update. If you had it before, perhaps it wasn't from that package.08:49
Tobias92The reason I noticed the change is that the reference disappeared from /etc/postfix/dynamicmaps.cf08:49
Tobias92This is strange, though, because Xenial includes postsrsd, which relies on this particular functionality of postfix.08:50
rbasakI don't know anything about this particular lookup type, sorry. If you conclude that there's a bug, please file one and let me know and I'll look into it.08:51
Tobias92I'll investigate some more first; thanks!08:51
Tobias92rbasak, turned out this looup was integrated into libpostfix-utils, so there was no cause for concern :)11:54

DVA5912Is there a new way of using network interfaces with ubuntu now? Im used to the old 14 style. Where i could just add it into the /etc/network/interfaces config file and it would bring up. However doing that now seems to break already existing interfaces.13:10
tomreynfor several releases, there has been network-manager in addition to the classic configuration via /etc/network/interfaces. netwokr-manager won't handle NICs if there is /etc/network/interfaces13:11
tomreynalso, NIC naming have changed in current releases13:12
DVA5912tomreyn: Saw that! :), Ok so network-manager is with this - now i know where to look. Thanks!13:12
tomreynwelcome :)13:13
DVA5912Server 17.04... That doesnt use the network-manager service does it? Everything im reading is all saying to set the connection configuration in the /etc/network/interfaces file. I did that before and it killed the prior established connection13:20
DVA5912Is it using network-manager GUI versions? That i cant access because im using console?13:21
DVA5912btw - im refferencing: https://www.linuxhint.com/change-from-dhcp-to-static-ip-address-ubuntu/13:22
tomreynDVA5912: there are nmcli and some text graphics based UI for network manager13:24
tomreynnmtui13:25
tomreynDVA5912: i do not know for sure whether 17.04 server uses network manager by default, but i would assume it does.13:25
tomreyni only use LTS releases on servers do i'm not into this one.13:25
tomreyns/ do / so /13:26
tewardgreetings Server peoples.13:28
DVA5912Luckly - this isnt production :) Taking my time to learn this before i push it out. Looks like it doesnt use Network-Manager, its not even installed. So i dont know whats allowing it to set a network connection.13:28
tewardrbasak: dpb1: powersj: and others who care: 18.04 is destined to be LTS right?  If that's the case, would any of you mind if I jumped to NGINX Mainline with intentions to bump it back to Stable come April?13:29
tewardlike we did for the 16.04 cycle13:29
DVA5912I think the best thing for me right now tomreyn is to define a whole interfaces file. That way i can feel like i have a little control left :)13:30
tomreynDVA5912: so "nmcli" (command, package) is not installed? or is it?13:35
tomreynif installed, run "nmcli c" and "nmcli n"13:35
tomreynbut the static configuration via /etc/network/interfaces is, of course, an option13:41
tomreyni'll bbl13:41
drabthanks dpb114:21
drabdpb1: any chance you looked at ELK too for time series? I'm probably going to need ELK fro logs and would love to avoid having to run both14:21
drabbut everything I read says ELK doesn't really fit the timeseries nature of many metrics14:22
drabdespite the new timelion interface14:22
drabso influx is still the right thing to go with14:22
arunpyasiHello everyone, I am having an issue ! I have a disk mounted and running and i have vsftpd running as ftp. Here, I have the link of the HDD under the folder where the ftp home is, when I try to login ftp, I get stuck at Retrieving directory listing.... How do I fix it ?19:26
arunpyasiHello !19:50
arunpyasianyone around ?19:50
drabarunpyasi: have you checked the logs? /var/log/syslog21:02
drabalso vsftpd has its own auth iirc, haven't used ftp in like decades... any reason you can't use ssh and sftp?21:03
drabother than for nostalgia sake and reviving the 80s, there seems to be no reason today to run ftp21:03
drabbut I like retro so you know...21:04
arunpyasidrab, I found that when I turn off nginx, I get to make sftp and ftp working... Yeah, ssh is working fine but not sftp.21:34
arunpyasidrab, so, can it be cause its using Disk I/O intensely that the ftp/sftp didn't get chance to work ?21:34
drabarunpyasi: seems unlikely, should only be taking long[er], but it may be hitting a timeout, altho then you should see an error, not just hanging21:53
drabI don't understand the comment about sftp21:53
arunpyasidrab, yes but it also hangs for sftp22:03
drablook at top, you should see a process maybe in D state, waiting for I/O22:06
drabor just look at top at the wa%22:06
