[00:18] <mgw> using vmbuilder inside a private network… should —proxy pointing to my apt-proxy URL be sufficient?
[00:20] <harushimo> I have maas setup. Is there another site for maas setup?
[00:24] <harushimo> I don't have the web interface for maas
[00:24] <pmatulis> harushimo: another one?  what are you after?
[00:25] <harushimo> I can't get it to add nodes
[00:25] <harushimo> web interface
[00:25] <harushimo> I'm not running a gui on the server
[00:26] <pmatulis> harushimo: what does that have to do with it?  a web server doesn't require a graphical environment
[00:26] <harushimo> how I access the http? then
[00:27] <harushimo> https://wiki.ubuntu.com/ServerTeam/MAAS#Create_MAAS_admin_account
[00:27] <pmatulis> harushimo: the same way you access any web site
[00:27] <pmatulis> harushimo: what happens when you point your browser to http://your_server_ip_address/MAAS   ?
[00:28] <harushimo> it keeps reloading
[00:28] <harushimo> I'm using maas on my virtual machine
[00:29] <harushimo> I'm guessing that doesn't matter
[00:29] <harushimo> it does
[00:29] <harushimo> it doesn't show anything
[00:30] <harushimo> sorry
[00:30] <harushimo> it is importing the isos right now
[00:30] <harushimo> i'm at that step
[00:30] <harushimo> I'm getting ahead of myself
[00:31] <harushimo> I just realized I need to change my default gateway
[00:31] <harushimo> I use the ip address to access my router setup
[00:31] <harushimo> how long does it take to import isos?
[00:32] <pmatulis> harushimo: i think it takes 4, all precise, by default.  so not long
[00:32] <pmatulis> harushimo: and take your time, haste makes waste (Ent saying)
[00:33] <harushimo> 4 hrs?
[00:34] <harushimo> I'm guessing that is what it is
[00:34] <pmatulis> harushimo: no, 4 images
[00:34] <harushimo> my bad
[00:34] <harushimo> sorry
[00:34] <harushimo> how long does 4 images take to download?
[00:34] <harushimo> i'm guessing that is dependent on the internet connection
[00:35] <pmatulis> harushimo: bingo
[00:35] <harushimo> thank you
[00:36] <harushimo> this is my first time doing maas. I may fail at it
[00:36] <harushimo> that is okay. I will learn something
[00:38] <pmatulis> harushimo: well, it's quite new.  it's bound to have bugs.  report back and let me know how it goes
[00:42] <harushimo> I will definately do that
[00:42] <harushimo> one thing I'm thinking
[00:43] <harushimo> please tell me if this isn't a good idea
[00:43] <harushimo> maas is use for some who has systems background
[00:43] <harushimo> this is just me saying: Why can maas have front end
[00:44] <harushimo> the user can click and get it done quite quickly
[00:44] <harushimo> if it does, I want to know about it
[00:44] <harushimo> hehe
[00:44] <harushimo> we can probably stream the process but like you said, it is new
[00:45] <harushimo> I will definately know about the bugs
[00:45] <harushimo> if this a bad idea, let me know also
[00:52] <harushimo> how many machines would need for maas?
[00:52] <harushimo> I mean ideally
[00:55] <harushimo> what is the difference between maas & enlightment or just doing an install of ubuntu server and then installing maas after the installation of ubuntu server?
[01:05] <harushimo> does maas cloud cd have 32 bit?
[01:05] <harushimo> I have the 64 bit iso
[01:06] <harushimo> anyone?
[01:11] <lux`> hi all
[01:12] <lux`> i've got an urgent problem
[01:12] <lux`> upgraded my server, screwed up with ip route (which should be only temporany, and reset after reboot), rebooted and can't access anymore to the server via ssh
[01:13] <lux`> I can access the server in rescue mode and from the syslog mysql and other startup programms are starting
[01:13] <ea1het_OFF> maybe you have a wrong routing table in your box
[01:13] <lux`> so I though it's a ip route problem, but shouldn't things modified with "ip" command be temporanyt?
[01:13] <ea1het_OFF> of course you have to clean it
[01:14] <lux`> i also tried ip route flush table main from the rescue mode chrotting the server ea1het_OFF
[01:14] <lux`> and after restarting to normal mode still doesn't work
[01:15] <ea1het_OFF> i'm not sure the rescue mode serves this matter....
[01:15] <lux`> well that's the only way i can access the server
[01:15] <ea1het_OFF> hum.. and i understand you don's have physical access to your server.... right?
[01:15] <lux`> nop
[01:16] <ea1het_OFF> the only idea i have is to create a shellscript you can configure... put it on the rc.local init script.... and that script flush all tables and set one and only one default route to your gateway
[01:16] <ea1het_OFF> maybe it works
[01:17] <ea1het_OFF> same command you introduce in the rescue session but inside a shellscript to automatically be executed from rc.local in the normal init run
[01:18] <lux`> k i'll try thanks
[01:19] <ea1het_OFF> you're welcome
[01:20] <harushimo> does anyone anything about maas here
[01:28] <Psi-Jack> Okay, so, I'm having some ANNOYING issues with nslcd NOT starting at boot-up in Ubuntu 12.04.
[01:29] <lux`> reading online they say that ip and route commands aren't permanent ea1het_OFF
[01:29] <lux`> also I tried to do as you said and it didn't work
[01:30] <ea1het_OFF> what do you have in your interfaces file (/etc/network/interfaces) ??
[01:30] <ea1het_OFF> take a look at the config for incoherences...
[01:31] <lux`> 1sec restarting to rescue mode
[01:33] <lux`> ea1het_OFF, the samething I've had for months
[01:34] <lux`> and these are the commands i've added to rc.local:
[01:34] <lux`> ip route flush table main
[01:34] <lux`> ip addr add 46.105.109.0/24 dev eth2
[01:34] <lux`> ip route add default via 46.105.109.254
[01:38] <ea1het_OFF> looks good
[01:39] <ea1het_OFF> lux`: ip route ls
[01:39] <ea1het_OFF> lux`: ip rule list
[01:39] <ea1het_OFF> ip route flush cache
[01:40] <lux`> i can connect only through rescue
[01:40] <ea1het_OFF> is the ssh daemon running in normal init?
[01:40] <lux`> always been
[01:41] <ea1het_OFF> if you don't have physical access ... how are you connecting to your box and changing the init level?
[01:42] <lux`> through a rescue system the hoster gives me ea1het_OFF
[01:42] <lux`> it let me connect to the real server harddisk
[01:42] <lux`> so i can chroot to it
[01:42] <ea1het_OFF> you are into a VPS ¿
[01:42] <ea1het_OFF> ?
[01:42] <lux`> anyway yeah, ssh is enabled in init level 2-5
[01:42] <lux`> dedicated server
[01:43] <ea1het_OFF> what did you tried before, when the connections stop working?
[01:43] <lux`> ip route del ?.
[01:43] <lux`> but as I said I read that it refresh every restart
[01:43] <lux`> shouldn't it?
[01:44] <ea1het_OFF> it should.....yes...
[01:44] <ea1het_OFF> did you do any kind of change to the network configuration files?
[01:45] <lux`> yeah actually I did, added another nic but i restarted network and everything was fine, anyway after I removed it thinking it was the problem
[01:45] <lux`> so now it's exactly how it has been for months
[01:46] <ea1het_OFF> when you enter in chroot mode... can you get access to the internet from your server?
[01:46] <ea1het_OFF> i don't want to think it's a temporary problem in your hoster....
[01:46] <lux`> yes
[01:46] <lux`> i can
[01:47] <ea1het_OFF> run in normal mode
[01:47] <lux`> can't access anything in normal mode :/
[01:47] <ea1het_OFF> telnet your_server_ip 22 from you pc and wait for a connection....
[01:47] <lux`> won't work
[01:47] <lux`> connection refused
[01:47] <ea1het_OFF> and tell me if if presents a prompt
[01:48] <ea1het_OFF> so only two things can happen.... no ssh daemon running in the correct interface.... or no interface well configured.
[01:48] <lux`> i can even start ssh in the chrotted env.
[01:49] <lux`> and /etc/network/interfaces is like it has always been
[01:49] <lux`> :(
[01:51] <ea1het_OFF> iptables -L -n
[01:51] <ea1het_OFF> to see if there is something blocking your machine
[01:52] <ea1het_OFF> (firewall rules i mean)
[01:52] <ea1het_OFF> any firewall daemon configured in the box?
[01:52] <lux`> i even removed iptables to make sure it wasn't it
[01:52] <ea1het_OFF> there is not so much....
[01:52] <lux`> so it can't be it
[01:52] <ea1het_OFF> execute the line above to be sure....
[01:53] <ea1het_OFF> or reboot your machine
[01:53] <lux`> command not found
[01:53] <lux`> i'll try to reboot with only the default nic
[01:53] <ea1het_OFF> good....
[01:55] <ea1het_OFF> lux`: it is not a good idea to configure interfaces and subinterfaces together
[01:56] <ea1het_OFF> if you are going to work with subinterfaces.... only configure subinterfaces for all networks
[01:56] <ea1het_OFF> without configuring the physical device
[01:57] <ea1het_OFF> about the rest...loooks good
[02:00] <lux`> nothing, I'll check logs to see if ssh is giving any error i guess
[02:05] <Psi-Jack> Hmmm
[02:06] <Psi-Jack> So, I've converted my nslcd init.d script into upstart scripts, and at startup it seems nslcd.conf actually IS running, but nslcd-k5start.conf isn't. Very strange...
[02:06] <Psi-Jack> is there a network-manager specific event?
[02:13] <harushimo> I've trying to setup maas. Is it possible to set it up on ubuntu-server 32 bit?
[02:18] <harushimo> can anyone help me with maas at all?
[02:18] <harushimo> I've been at this problem for a week
[02:18] <harushimo> the instructions are 64 b it iso
[02:18] <harushimo> not for 32 bit
[02:26] <lux`> what the fuck
[02:26] <lux`> i even put debug to log level of sshd
[02:26] <lux`> and it's not showing NOTHING AT ALL
[02:32] <pmatulis> lux`: language please.  what's the problem?
[02:36] <harushimo> pmatulis: can I ask you a question
[02:36] <harushimo> you helped a couple hours ago
[02:37] <harushimo> is it possible to install maas on ubuntu-server 32 bit
[02:37] <harushimo> ?
[02:37] <harushimo> when I look at the instructions, it is for 64 bit
[02:39] <lux`> pmatulis, sorry i'm very frustrated, it's almost 5am here and still can't fix the server, anyway there is a discussions of like 50lines if you scroll on the top
[02:39] <pmatulis> harushimo: yes, you can
[02:39] <pmatulis> lux`: yes, i read it now
[02:39] <harushimo> how
[02:40] <harushimo> I've been really struggling here
[02:40] <harushimo> there are no instructions for the 32 bit
[02:40] <lux`> install lsh-server now? so i'll check if there is a problem with openssh or something else
[02:40] <pmatulis> harushimo: well, get yourself a 32bit-based machine and away you go
[02:41] <harushimo> i'm running 32 bit vm
[02:41] <harushimo> that I know
[02:41] <pmatulis> harushimo: so what's the problem?  just 'apt-get install maas'
[02:41] <harushimo> alright
[02:41] <harushimo> that is easy
[02:41] <harushimo> I'll install the ubuntu-server
[02:41] <harushimo> okay I see now
[02:42] <pmatulis> lux`: so you put in a bad route with the ip command and now you cannot ssh into the machine?
[02:43] <lux`> exactly, but everything done with the ip command should be temporany right pmatulis ?
[02:43] <lux`> so now I'm thinking that there is a problem with ssh
[02:43] <pmatulis> lux`: yes, it won't survive a reboot
[02:44] <lux`> and also I'm not reading from the first "faulty" reboot anything about ssh in /var/log/auth.log
[02:44] <lux`> not even putting the log level to "DEBUG" in sshd's config, so there is something wrong I guess
[02:44] <pmatulis> lux`: is the ssh daemon running?
[02:45] <lux`> how can I know, it's not visibile from the outside anyway
[02:45] <lux`> nor in the logs
[02:45] <pmatulis> lux`: with the ps command
[02:45] <lux`> I can't access the machine in normal mode
[02:45] <pmatulis> lux`: i thought you had an alternative method
[02:46] <lux`> yes I can connect in "rescue mode", basically I can connect to a temporany computer which got access to the main server's hdd
[02:47] <pmatulis> lux`: so you can read data on the drive?  browse the filesystem?
[02:47] <lux`> yes
[02:47] <pmatulis> check if there is a pid file for sshd
[02:48] <pmatulis> what release are you running there?
[02:48] <lux`> nop no pid pmatulis
[02:49] <pmatulis> what release are you running there?
[02:50] <lux`> 12.04
[02:52] <pmatulis> where did you check for the pid?
[02:52] <lux`> /var/run/sshd/
[02:53] <pmatulis> try /run/sshd.pid
[02:53] <lux`> nothing
[02:53] <pmatulis> did you much around with /etc/ssh/sshd_config at all?
[02:54] <pmatulis> *muck
[02:54] <lux`> don't remember doing so, anyway now i'm installing lsh (taking so much time to create the random seed) and then if it doesn't work I'll try to purge and reinstall openssh
[02:54] <lux`> but the odd thing is that there is no error nor anything at all about ssh in the logs pmatulis
[02:55] <lux`> since the server problem
[02:55] <pmatulis> lux`: you did a 'grep sshd /var/log/syslog' and no error?
[02:55] <lux`> yeah and also /var/log/auth.log
[02:56] <pmatulis> well, the reason why you can't ssh into the box is because sshd is not running
[02:56] <pmatulis> auth.log will be empty of anything useful if sshd is not running
[03:05] <lux`> yes yes yes
[03:05] <lux`> changing ssh server worked
[03:05] <lux`> my eyes are gonna cry blood in the pain of frustation
[03:05] <lux`> it's 5am but it's all right
[03:11] <mgw> what would be the implications of having, say, 500 ssh tunnels open at once?
[03:11] <mgw> to remote machines
[03:11] <pmatulis> lux`: so you can log in now?
[03:12] <qman__> mgw, lots of CPU overhead for the encryption
[03:12] <lux`> yes and i don't even wanna know what's wrong with openssh
[03:12] <lux`> i even purged an reinstalled it
[03:12] <lux`> it didn't work
[03:12] <lux`> using dropbear now
[03:12] <qman__> each tunnel has to run the expensive RSA for the handshake, but then also has to keep up the AES tunnel
[03:13] <lux`> and i can finally go to sleep, the sun is rising...
[03:13] <lux`> gnite and thanks pmatulis ea1het_OFF
[03:13] <mgw> qman__ thanks… so it wouldn't work very well
[03:13] <mgw> if at all
[03:13] <qman__> well, it'll work if you have enough CPU
[03:13] <mgw> ok
[03:13] <mgw> any idea how much?
[03:13] <qman__> any CPU made in the last few years can handle that, but it's a nontrivial amount of computation
[03:14] <qman__> that you have to take into account when designing the system
[03:14] <qman__> if that's all you're doing, a modern chip can handle it
[03:14] <mgw> ok, but 100 would be more doable, even on a smaller system then?
[03:14] <pmatulis> lux`: good.  let me know why sshd could not start.  g'night
[03:15] <qman__> it can, but on a typical desktop, doing 100 SSH tunnels with AES256, expect between 10% and 30% CPU use
[03:15] <qman__> you'd have to do some tests to get actual numbers, but IME it should be in that ball park
[03:16] <qman__> my 200MHz K6 starts to choke at about 6
[03:17] <mgw> qman__ thanks
[03:17] <mgw> would I need to look at ulimits to open this many?
[03:18] <qman__> no, by default the limits aren't set
[03:18] <qman__> now, those numbers also depend on the amount of traffic going over those tunnels
[03:19] <qman__> idle tunnels or light communication doesn't need as much CPU power as, say, a file transfer
[03:20] <mgw> qman__ obviously
[03:20] <mgw> i'm not sure i'd actually use a tunnel… maybe a straight ssh connection, but keep them open
[03:21] <mgw> I'm trying to optimize an application that opens and closes connetions repeatedly
[03:21] <qman__> my K6 can't actually keep up with an SFTP transfer, it's notably slower than my uplink
[03:22] <mgw> ok… but that's a K6
[03:22] <mgw> ;-)
[03:22] <qman__> it is, just making the point that a file transfer takes more than 7 or 8 open SSH sessions
[03:22] <mgw> ah, understood
[03:22] <mgw> ok, so this is how the system currently works
[03:23] <mgw> if I'm working with 100 systems, it forks 10 processes (say) and opens 10 connections at a time
[03:23] <mgw> closes them, and and loops through the 100 servers that way
[03:23] <mgw> for each task
[03:23] <mgw> then it starts over
[03:23] <mgw> for the next task
[03:23] <qman__> that's going to be really inefficient if you have more than one task per server
[03:23] <mgw> is the opening/closing more intense than keeping them idel?
[03:24] <qman__> much more
[03:24] <mgw> ok, that's what I was hoping
[03:24] <qman__> you're talking about 2048-bit (or more) RSA per connection
[03:24] <mgw> b/c it's also really slow
[03:24] <qman__> versus keeping an AES256 open
[03:25] <mgw> hoping, b/c I want to make this more efficient
[03:25] <qman__> and that isn't 8 times more complex, it scales exponentially
[03:27] <qman__> you're going to want to keep the tunnels open as long as is practically possible
[03:28] <qman__> they do die off with flaky connections after a while, so you might want to make them no more than an hour long depending on your network and application
[03:28] <qman__> but that's the range you're going to want to shoot for, not seconds or minutes
[03:36] <mgw> qman__ I don't really need them for more than a few minutes
[03:36] <mgw> right now they're being opened/closed several times a minute
[03:37] <mgw> maybe 15 minutes if there're a lot of longer tasks
[03:48] <mgw> qman__ one more question… if I open a tunnel via a subprocess, will the tunnel close when the parent process dies?
[08:10] <joseph__> Why does byobu look bad over ssh?
[08:45] <RoyK> joseph__: it does?
[08:47] <joseph__> yea maybe a bug. there is a scolling problem had to disable the logo to fix that. but i am trying to fix this http://img600.imageshack.us/img600/401/screenshotfrom201206020.png
[08:49] <RoyK> looks like a curses bug
[08:49] <RoyK> file a bug :)
[08:49] <joseph__> what should i use tmux or screen
[08:49]  * RoyK just uses screen
[08:50] <joseph__> it looks even worse when i use tmux.
[08:50] <RoyK> joseph__: but please file a bug - bugs aren't fixed unless reported
[08:58] <joseph__> file the bug report https://bugs.launchpad.net/byobu/+bug/1007753 should of explaned it better
[09:00] <joseph__> start up a ec2 instance and run byobu. the status bar infinitty scrooling bug is already filed.
[10:24] <chmac> `hostname` is returning blah instead of blah.domain.tld, I've reset /etc/hostname and rebooted, but every time it reverts to just blah.
[10:24] <chmac> Any ideas?
[10:24] <Jeeves_> vi /etc/hosts
[10:24] <Jeeves_> hostname -f will probably give the full hostname
[10:25] <lux`> how can I use ip route or ifconfig to use another nic and not the default one for an IP?
[10:26] <Jeeves_> ip addr add 192.168.1.1/24 dev ethx
[10:26] <Jeeves_> Oh wait
[10:26] <Jeeves_> route
[10:26] <lux`> and then ip route add outgoing_ip via secondary_nicip?
[10:26] <Jeeves_> You want to route a specific network over another interface?
[10:27] <lux`> I want to use a specific NIC for a specific IP
[10:27] <lux`> so when i connect to the specific IP it uses the specific NIC
[10:27] <lux`> and not the default one
[10:28] <Jeeves_> ip route add <dstip> via <dstgw>
[10:29] <lux`> tried already, gave me no such process error
[10:29] <lux`> RTNETLINK answers: No such process
[10:29] <chmac> Jeeves_: I've tried setting the fqdn into /etc/hostname, but it gets overwritten on reboot. It's a proxmox virtualised machine, so maybe there's something going on there, not sure...
[10:29] <Jeeves_> /etc/hostname is being overwritten?
[10:29] <Jeeves_> In Ubuntu?
[10:31] <viezerd> try /etc/init.d/hostname.sh start after editting
[13:08] <qman__> mgw, yes, the tunnel will close when the parent process dies
[15:50] <pats_Toms> hi, is there someone who can help me finding the way to multiarch on linux? I want to run 32bit game server on 64bit ubuntu
[16:29] <harushimo> I installed maas and it gave me my web interface
[16:29] <harushimo> when I try firefox, i can't use it
[16:30] <harushimo> I'm using this on my virtual machine
[16:35] <harushimo> I don't understand why I can't see it on my computer
[18:53] <Psi-Jack> There we go, FINALLY resolved my fricken nslcd issues with it not starting up properly at boot.
[18:54] <Psi-Jack> Fixed it by converting my dnsmasq, and nslcd init.d scripts into upstart scripts.
[18:55] <mgw1> qman__ thanks, that's what I thought
[19:32] <harushimo> anyone know maas here
[19:32] <harushimo> how come I can't access the web interface
[19:32] <harushimo> I have maas installed on my virtual machine
[19:33] <harushimo> I can't access the web interface at all
[19:33] <harushimo> do I need to import isos first and then access the web interface
[20:00] <harushimo> http://cloud.ubuntu.com/
