jlacroixHello everyone. I have an LXD server (18.04) with five containers running on it. The containers have very low usage, it's more of a test server for me to play with than it is a production system. My issue is that it runs VERY slow. For example, if I run: apt dist-upgrade (for example) it takes a very long time, it seems that it can take 30-60 seconds to install any app (the packages seem to download fast though). I was hoping someone03:07
jlacroixcan provide documentation links to what I can do to tune it, I wasn't able to find anything03:07
jlacroixAlso, it's installed via snap, if that matters03:08

Neo4https://ssl-tools.net/mailservers/mail.kselax.ru12:18
Neo4What shall I do for correct those all?12:19
lordievaderNeo4: You don't want to use a self-signed certificate.12:27
Neo4lordievader: see, there weak ciphers, do you know how I could forbid weak ciphers?12:30
Neo4and should I forbid them?12:30
lordievaderI try to stay away from mail servers, so no. Read the documentation of your mail server.12:30
Neo4lordievader: how TLS works?12:31
Neo4there ssl312:31
lordievaderBut weak ciphers is less of a problem than a self signed certificate.12:31
OpenTokixlordievader: no12:31
OpenTokixSelf signed cert is no less secure then a signed cert.12:31
lordievaderFair enough.12:32
Neo4not bad? :)13:15

blackflowNeo4: blacklisted by Spamhaus? you're better off getting a new IP. Preferably with a reputable hosting provider that is not blacklisted.13:28
Ussatand stop what ya doin to get blacklisted13:34
Neo4blackflow: can I write them and ask kick me from black list I won't more?13:36

enoch85hey, I'm having issues with setting static IP with netplan20:49
enoch85I use the following YAML: https://codebeautify.org/yaml-validator/cbd763fb20:49
enoch85which is valid20:49
enoch85but netplan apply gives an error20:49
enoch85Error in network definition //etc/netplan/01-netcfg.yaml line 4 column 13: expected mapping20:49
naccenoch85: oh, sorry, i think your indentation is wrong maybe20:49
naccenoch85: you should be indented below the ens32: line, no?20:49
naccenoch85: yaml is sensitive to the layout20:50
enoch85nacc, yeah I know yaml is sesetive, and I really don't like the fact the ifupdown is depcrecated in 18.04, but yeah... why does a valid yaml gives an error20:51
enoch85hwo should I intendent exacly?20:51
enoch85how*20:51
naccenoch85: well 'valid' just means it parses20:51
naccnot that it's well-formed20:51
enoch85ok, hmm20:51
naccenoch85: you are defining ethernets, which means the first entry is the key into that dictionary (that's how i think o fit)20:52
enoch85so is it 2 spaces between every intended line?20:52
naccso everything for ens32 should be under ens32: indentend20:52
nacc*indented20:52
naccotherwise, it thinks you are defining an empty (or invalid) ens32 entry, then a dhcp4: entry (also invalid), etc.20:52
powersjalso take a look at: https://netplan.io/examples#dhcp-and-static-addressing20:52
naccpowersj: thanks!20:52
naccenoch85: i say this knowing next to nothing about netplan syntax, just based upon judicious use of parsing :)20:53
enoch85ok, so it works now :)20:53
enoch85https://codebeautify.org/yaml-validator/cb8a1a2420:54
enoch85thanks ncc20:54
enoch85nacc, powersj20:54
naccenoch85: yw20:55
naccenoch85: it helps to translate the yaml into a dictionary20:55
naccenoch85: to see how it's actually going to be used20:55
enoch85nacc, I know what dictionary is, but what do you mean in relation to netplan?20:58
naccenoch85: the yaml is being transformed into a dictionary21:02
enoch85nacc, aah ok21:02
naccenoch85: so if you had read your original, as a dictionary, i think you would have seen the error immediately21:02
cyphermoxI have code in progress that should improve the error reporting21:02
nacccyphermox: nice21:04
nacccyphermox: yeah there seem to be 'classes' of errors21:04
naccfrom parse failures to structural issues21:04
