mercutio, everything wireless hetr almost always uses 2.4 .. coordless, wireless kb/mice, some wifi, bt and some hdmi wifi is 2.4 but mostly 5ghz mercutio: it was just dect phones that i wasn't sure of
wireless speakers, kb, mice, bluetooth etc are all 2.4 :( grody: i would post ubi spec analasys but its a little sesnitive
dect here uses 2.4
mine does but thankfully a low channel away from wifi prinary
its bt that savages me
there is a lot of that in these flats ands its weird mercutio: weird
i thought bt was short range grody: i have upto 100m stuff, small apartment, sound throughout mostly via bt .. it hits 2.4 rotten, use the phone too whist torrenting for ex.... u get the pictute mercutio: i want to do multiroom audio, but i dunno how to sync it
i figure if i used wireless latency can vary?
and i don't know how much it matters.
i mostly just want to extend music into kitchen up_the_irons: there is so much layer 2 / 3 geekery talk in here, i love it
someone in here's gonna invent a new protocol ix33: ha i thought with that discussion that this was the #lopsa channel -: up_the_irons checks out the #lopsa channel mercutio: i've been trying to figure out this damn complicated netfilter mess
it's insane now days
with pf you can just pass "no state"
with iptables if you want to remote state it's /way/ more complex staticsafe: unloading nf_conntrack usually works BryceBot: That's what she said!! staticsafe: :P
its ugly but it works mercutio: until you need it static :)
it's when you want to combine connection tracking and non connection tracking that it gets complicated.
it's with tproxy i found i needed connection tracking ***: lily has joined #arpnetworks lily: hello mercutio: hi ***: lily has quit IRC (Ping timeout: 250 seconds)

starlily is now known as lily mnathani_: should I be concerned if my VPS is using 181megs of swap space
even though +/- buffers has 1960 free mercutio: yes you should be
linux overswaps :/
freebsd can swap quite a bit if it runs out of memory
uhh what's with ntt's reverse dns?
http://pastebin.com/cSBrFB3q mjp: you can tune swap usage with sysctl vm.swappiness on linux
i dont think freebsd lets you tune though mercutio: with freebsd if you're swapping that much i'd say that you don't have enough memory, or should reduce your memory footprint
with linux i'd say vm.swappiness liek mjp said :)
there's been a growing trend these days to not even have swap mjp: no swap is a pretty bad idea imo mercutio: why's that?
i think level3 is having congestion again mjp: because it will cause things to break/crash if ram usage gets to 100% mercutio: ram usage should never be anywhere near 100% these days
and lots of things break when swapping mjp: but it does happen, especially when you use VMs and only allocate 1G/2G for 'average' sort of hosts mercutio: like if you're serving web pages, with mysql+apache, and you start swapping the performance is so bad it'll spawn more processes
and use more and more ram
and so the swap just "delays" time to killing process.
i think in a way there should be better memory controls to stop things getting out of hand.
but atm a lot of people have more ram than they need most of the time mjp: we usually set swap at 1GB or 2GB per host regardless of actual RAM size and set nagios to alert us if the box starts swapping mercutio: there's always that compressed swap thing
compressed ram as swap
you could alert on low buffers/cache as well i suppose
but yeah i suppose it's easy -: mercutio has no swap on his personal desktop mjp: depends if you would rather recover from a crash or tune a slow host heh mercutio: i haven't seen hard-crashes relating to swap or lack of swap
i just see things like mysql getting killed mjp: yeah oomkiller
which is essentially a mysql crash from its perspective mercutio: yeah
i dunno, overprovisioning memory is much more common than it used to be mnathani_: whats a good way to tell whats using the swap mercutio: mnathani_: rss being low normally
err res mjp: top? heh mercutio: but it's hard to know what's low :)
there's also paging out of executable
like executables are demand-loaded, and it can free the executable pages and demand load them back in
which is essentially like swapping except without the extra write
and on some systems like freebsd it can write to swap without actually using the ram it's created
so that there's more ram available "if needed" and it doesn't have to wait for it to swap it out. mjp: yep mnathani_: RES PID USER PR NI SHR S %CPU %MEM TIME+ TIME COMMAND
65m 10526 mnathani 20 0 2292 S 0.7 2.7 2201:50 36,41 weechat-curses mjp: i dont think the way freebsd uses swap
*dont like mercutio: i used to use this tol that told you how much library space etc everything used. mjp: swapoff -a && swapon -a will fix it though mercutio: 65mb seems heaps mjp: not a good solution mercutio: i can't remember the name of it, but often in times gone past it was huge libraries being used that used up lots of memory
so i compiled things without the huge libraries etc.
but that was when i had 24mb of ram..
weechat can restore state
so you can save state and restart it
also if you upgrade libraries on a running system then old programs will use the old version, and new programs the new version
so it has to store two copies in memory
how much ram does your vps have? mjp: why would you ever want to save the state of a chat client? mercutio: my weechat is only using 24mb
mjp: so that you have all your windows etc from last time mjp: wouldnt that be in the config? mercutio: is it?
it's not in mine i think mnathani_: some of my windows are in the config mjp: when i fire up irssi it connects to all my irc servers and auto-joins my channels mnathani_: a lot of it would not be mjp: otherwise it runs inside of screen mercutio: my irssi never did that mnathani_: its been a while since weechat was launched mercutio: and my weechat doesn't afaik
i've hardly started weechat
i've used it quite a lot :)
why does weechat have kerebos support?
kerberos.
and ssh support
i don't even know what libhogweed is
but if you want to be anal about memory usage, you can probably reduce memory usage by compiling without lots of these modules
although ime a lot of the worst offenders are things like perl programs.
apparently weechat older versions have some memory leaks
so restarting it may improve memory usage. mnathani_: I am hesitant to restart my weechat
might not come back the way it goes down brycec: hogweed - low-level crypto library
my weechat isn't linked against ssh mnathani_: I am behind on a lot of scrollback brycec: and kerberos is linked-against by way of other libs mercutio: i have 29 libraries linked brycec: (weechat itself isn't linked against kerberos) mercutio: how can you tell if it's direct or through other links? brycec: (oh I do see libssh2 there) mercutio: erk it's using libgnutls brycec: mercutio: ldd -v $(which weechat)
the -v will break it all down mercutio: it's using both libssl and gnutls
isn't that license violation?
hmm i have no idea about this license stuff
it's too confusing.
i seem to remember openssh was removing the need for libressl though, so maybe there's some more minimal base that'll get improved?
hmm without libssl openssh doesn't like my key mnathani_: Implementing Dual-Stack with no strategy to move to Single-Stack IPv6 will end up
costing your organization more in the long term.
^ Is that true? mercutio: it sounds like an open ended question mnathani_: should that be the eventual goal? moving to ipv6 only networking? mercutio: nope
not to my mind :) mnathani_: so, ipv4 will probably not be decomissioned in our lifetimes mercutio: well ethernet still exists.
