| Calif | I'm using this tutorial to configure a dhcp server | 01:03 |
| Calif | http://www.howtoforge.com/dhcp_server_linux_debian_sarge | 01:03 |
| Calif | However, I'm not sure how to start it, the command in the tutorial didn't work. | 01:03 |
| Calif | 'no such file or dir' | 01:03 |
| ChmEarl | Calif, cause its called dhcp3-server? | 01:09 |
| Calif | well, I'm sure its sometihng stupid like that | 01:10 |
| Calif | I've got dhcpd.conf | 01:10 |
| Calif | I don't know, maybe this isn't even the right tutorial, I thuoght that was what they had promoted | 01:11 |
| ChmEarl | Calif, dhcpd.conf is used here on lucid-server, but in /etc/dhcp3 | 01:12 |
| Calif | ok, let me try something | 01:13 |
| Calif | one sec | 01:13 |
| Calif | ok, I've messed this up good | 01:14 |
| Calif | I should probably start over | 01:14 |
| Calif | I just want a simple dhcp server, whats something that I can get with apt-get, that you would recommend? | 01:15 |
| Calif | is this dhcp3-server good? Would you have used something else? | 01:15 |
| Calif | fuck it, I made a backup ill just start over | 01:19 |
| JanC | Calif: dhcp3-server is good, but if you only need a simple DHCP/DNS server for a small LAN, you can also look at dnsmasq | 01:21 |
| Calif | Here's another question | 01:23 |
| Calif | # No service will be given on this subnet, but declaring it helps the | 01:23 |
| Calif | # DHCP server to understand the network topology. | 01:23 |
| Calif | #subnet 10.152.187.0 netmask 255.255.255.0 { | 01:23 |
| Calif | #} | 01:23 |
| Calif | What is this subnet - is this the external, internal, whats the point of this part? | 01:23 |
| ChmEarl | Calif, that only applies if you have a 10.x.x.0 private lan | 01:26 |
| Calif | what if I have a different address, but it's still a private address scheme on the lan I wish to use dhcp with? | 01:27 |
| Calif | eg: 192, or 172 | 01:27 |
| ChmEarl | Calif, keep reading the samples, they show an example | 01:27 |
| ChmEarl | /usr/share/doc/dhcp3-server/examples/dhcpd.conf | 01:28 |
| Calif | I'm looking at a few under that | 01:28 |
| Calif | So the purpose of these lines is just to show different config examples, the above one being the simplest? | 01:29 |
| Calif | further more, the above one can remain commented without affecting anything? | 01:29 |
| Calif | I'm running this on a linux box thats doubling as a router/fw for my network | 01:30 |
| Calif | so I want to offer dhcp services to the internal | 01:30 |
| Calif | that said, the external interface is dhcp as well, but it gets its address from an upstream router | 01:31 |
| Calif | I'm sorry for all the questions, I'm just trying to wrap my head around this. | 01:32 |
| JanC | Calif: for a small LAN, dnsmasq is much easier to set up & includes a DNS relay server (but lacks several more advanced features that dhcp3-server & bind support) | 01:33 |
| ChmEarl | Calif, your internals are limited to certain nics: in dhcp.conf I have - INTERFACES="eth1 eth2" | 01:33 |
| ChmEarl | eth0 is for my WAN | 01:33 |
| Calif | dhcpd.conf doesnt allow me to specify the interfaces | 01:34 |
| Calif | That said, if I just uncomment one of these, and give it the addresses of my internal interface, can I expect that to work? | 01:35 |
| Calif | Or is there some other place I specify the interface I want to use? | 01:35 |
| * ChmEarl slaps Calif with a trout: I just gave you the line | 01:36 | |
| Calif | you said dhcp.conf | 01:36 |
| Calif | So i have to edit that file as well? | 01:36 |
| Calif | or did you typo it | 01:36 |
| Calif | and meant dhcpd | 01:36 |
| Calif | I swear, I wish I knew this stuff like you guys do ;p | 01:37 |
| Calif | I'm like 10 years behind or something until a month ago, the most advanced thing I did was setup an eggdrpo | 01:38 |
| Calif | now im running a server with a firewall, and dhcp, I'm setting up nagios | 01:38 |
| Calif | but I am fairly challenged by these tasks, it's going to be a long time before I understand nix like some of you guys | 01:38 |
| JanC | Calif: reading up on basic networking and what DHCP does might be useful ;) | 01:39 |
| Calif | I've got basic networking, and I understand dhcp, but I'm coming from windows so there's a disconnect | 01:39 |
| JanC | it works exactly the same in Windows ;) | 01:40 |
| Calif | it works the same, but the setup is radically different ;p | 01:40 |
| Calif | it's similiar in the physical settings | 01:40 |
| Calif | but how you put it all together, and knowing what to edit where, I get confused easily | 01:40 |
| Calif | I can set this up on windows server with my eyes closed - setting up reservations, static assignments, ranges, all sorts of stuff | 01:41 |
| Calif | And I've read stuff on linux too | 01:41 |
| Calif | You all probably know the 'linux newbie administrator guide; | 01:42 |
| Calif | I've read that twice over the years, (not to say I'd not benefit from another round mind you.) | 01:42 |
| Calif | with me, I think, the trouble is I read stuff and it makes sense, but I need to _do_ it for it to sink in | 01:42 |
| Calif | and half the tutorials I find on stuff leave things out, or expect and assume you know some small detail... You can't ask a tutorial a question... so I wind up here | 01:43 |
| Calif | anyway, so back to this - I think if I can figure this out, I'll be able to do the rest and run this thing in a few minutes | 01:44 |
| Calif | I'm going to go look at your dhcp.conf, and see if that answers my question | 01:44 |
| Calif | well, my dhcp.conf ;p | 01:45 |
| Calif | ok, so using the locate command, I found a copy of that in the /etc/samba dir | 01:46 |
| Calif | is it supposed to be an empty file ? | 01:46 |
| Calif | probably.. | 01:46 |
| Calif | ChmEarl, I just add the INTERFACES="ethx" - x being the interface going out to my internal network that I want to offer dhcp services on? | 01:47 |
| JanC | I suggest you don't go looking for similarly named files in random other directories ;) | 01:48 |
| Calif | lol | 01:48 |
| Calif | So was he meaning to tell me to edit dhcpd.conf with that line, or did I miss something entirely here, because locate only came up with one file | 01:49 |
| Calif | if it is dhcpd.conf where in the file do I stick that line at? | 01:50 |
| Calif | I'm sure once I get the interface and that line I pasted earlier figured out, that would be all my questions for tonight ;p | 01:51 |
| Calif | There is an end to the madness I promise ;p | 01:51 |
| Calif | I know im close, it'd suck to abandon this 70% through to pick another dhcp server, that I'll probably likewise have dumb questions about... | 01:53 |
| Calif | chm, I didn't pm you without asking, I used notice - I'm making an effort :P | 01:55 |
| JanC | Calif: I configured my first gateway with dnsmasq in less than 30 minutes ;) | 01:57 |
| JanC | less than 15 maybe | 01:58 |
| Calif | If I can figure out what I need to do next I'd be done in 2 | 01:58 |
| JanC | and I suppose dhcpd.conf is the file for the DHCP server config | 01:58 |
| Calif | I believe so | 01:58 |
| Calif | I can paste you the contents in a pastebin if you think you could help | 01:59 |
| Calif | I think it's simple, but I know there's something to what chm said too about defining my interface | 01:59 |
| Calif | I know the info I want to put in for my network, but there's some stuff it says mainly for the examples that confuses me as to why they worded it like that | 01:59 |
| Calif | I'm tempted to ignore that part and just uncomment one of teh examples, change some stuff to my info, but that leaves the interface thing chm spoke of, that I can't figure out where to put it "INTERFACES="eth1 eth2"" | 02:00 |
| Calif | Sorry, lost my connection | 02:02 |
| Calif | My room mates coming home soon, I may have to give up soon | 02:04 |
| JanC | well, 3am here, so I give up now :P | 02:05 |
| twb | dnsmasq ROCKS | 02:05 |

| Calif | I'm not using dnsmasq I don't think | 02:06 |
| twb | Oh sorry | 02:06 |
| Calif | dhcpd.conf | 02:06 |
| twb | Then I can't help :P | 02:06 |
| Calif | crap :/ | 02:06 |
| Calif | lol | 02:06 |
| Calif | ok, I promise if I don't figure this out in a day or so | 02:07 |
| Calif | that will be the first thing I try | 02:07 |
| Calif | I'm already mostly through this one | 02:07 |
| Calif | so I'm hoping to finish it before I jump to another one | 02:07 |
| Calif | it'd be nice to figure out both in the end | 02:07 |

| jkakar | Hi! I've got a server running my application. | 11:32 |
| jkakar | I've created an Upstart script to start it. | 11:32 |
| dany_ | well i cannopt get zarafa an a joomla website to play nice on an OpenVZ container | 11:32 |
| dany_ | so thats why i am trying this way | 11:32 |
| RoyK | ok - never tried openvz | 11:33 |
| jkakar | Previously, we were using start-stop-daemon, but I've removed it (because I made some changes and it was causing problems), so Upstart is starting the service directly now. | 11:33 |
| jkakar | I notice that the Debian guidelines recommend start-stop-daemon, but is this the recommendation for Ubuntu+Upstart? | 11:33 |
| RoyK | jkakar: both work | 11:33 |
| jkakar | RoyK: I guess they're kind of equivalent. | 11:34 |
| RoyK | just different ways to do things | 11:34 |
| jkakar | In this case my application is Twisted based and started by twistd. I guess the reason to use start-stop-daemon would because (apparently) twistd's ability to switch to the right user can be dodgy. | 11:34 |
| RoyK | but - anyone that knows what might cause this? http://paste.ubuntu.com/603635/ | 11:35 |
| soren | jkakar: start-stop-daemon is used to daemonise things that aren't very good at daemonising on their own. upstart is a proper process supervisor. You don't need start-stop-daemon with upstart. | 11:38 |
| jkakar | soren: Cool, that's my impression. | 11:39 |
| jkakar | I just need to test my application to make sure it switches users properly. | 11:39 |
| soren | jkakar: If not, I use su to do that in upstart. | 11:40 |
| soren | e.g.: | 11:40 |
| soren | exec su -c "nova-api --flagfile=/etc/nova/nova.conf" nova | 11:40 |
| jkakar | soren: Ah, interesting. | 11:41 |
| jkakar | soren: Thanks for the advice. It helps. :) | 11:41 |
| soren | jkakar: It's not pretty, but until upstart learns how to do this natively, that seems to be the common pattern. | 11:41 |

| JanC | I think btrfs.mod is rather new though | 13:26 |
| webwurst | JanC: boot is a directory. would it maybe help to make it subvolume and put it indo /etc/fstab? is grub-installer searching for something like that? | 13:27 |

| rafalk42 | ok, so in fact you CAN dist-upgrade directly from 09.04 to 11.04 ... altough with a few issues | 14:45 |
| Pici | rafalk42: Just because you can doesn't mean you should. | 14:48 |
| rafalk42 | yeah, but I didn't knew about that before i started | 14:52 |
| hw | hey | 14:55 |
| rafalk42 | hi | 14:55 |
| hw | anyone have any ideas on this one? I have a U 10.04.2 box that needs apache and mysql updated... when I run apt-get update, apt-get upgrade it doesnt pick up the newer versions | 14:56 |
| hw | it has apache 2.2.14, and the latest is 2.2.16 | 14:56 |
| hw | any ideas? this one is kicking my butt :-( | 14:56 |
| hw | I see I could go to 10.10, but this has 10.04.2 LTS, not sure if I can upgrade... looking at this for a friend | 14:57 |
| Pici | 2.2.14-5ubuntu8.4 is the latest version in 10.04. | 14:58 |
| hw | so, when will this get updated? 2.2.14 has some security holes that make it fail a PCI scan | 14:58 |
| hw | or is really my only option to install 10.10? | 14:59 |
| hw | 10.10 I saw has apache 2.2.16 | 14:59 |

| Pumpkin- | the maximum number of PTY's (assuming the SSH connections have PTY's) is one thing. | 15:05 |
| Pumpkin- | think the default is 4096 | 15:05 |
| pmatulis | i'm seeing disconnections after about 80 | 15:06 |
| genii-around | The default number per connection I think is like 10 | 15:06 |

| ScottK | hw: No, actually it doesn't have security holes. What's happening is some brain dead security tool is looking at version numbers and not checking for actual vulnerabilities. Ubuntu backports security patches. | 15:17 |

| genii-around | ( sshd_config ) | 15:17 |
| hw | ScottK Yea, basically the issue is securitymetrics did a quarterly PCI scan, and that failed. | 15:17 |

| ScottK | I did. | 15:20 |
| hw | kees: ScottK: thank you!! let me review what the tool reported | 15:20 |
| ScottK | Clearly I'm not leveraging other people's ignorance nearly hard enough. | 15:20 |
| kees | use of EHLO is not a security issue. :P | 15:20 |
| patdk-wk | these whole security scan things seem so silly, the more I see people use them | 15:20 |
| ScottK | kees: It was on postfix-users. | 15:20 |
| hw | yea, I agree. I've had to call the security scan providers a few times to get them to remove bogus stuff | 15:21 |
| hw | usually they do it without any issue, as long as you are technical enough | 15:22 |
| patdk-wk | now that, make me even more scared :) | 15:22 |
| patdk-wk | your paying them to be technical enough to do the scan | 15:22 |
| patdk-wk | not for you to tell them how to scan | 15:22 |
| kees | indeed. | 15:22 |
| patdk-wk | if your a 3rd party in this, then ya, I can understand :( (customer hired x to scan their hosting stuff on your equipment) | 15:23 |

| patdk-wk | it's what burocrates are good at | 15:24 |

| robo | hi: if i add a mount to /etc/fstab and it's options are .... nfs ro 0 1 -- the mount doesn't get added at boot. Any suggestions? | 16:12 |
| oCean | robo: the mount options should be separtated by comma nfs,ro -not sure if that's your entire issue though. You don't have to reboot to test. Just run 'sudo mount -t nfs -a' | 16:14 |
| oCean | *separated | 16:14 |
| JanC | eh, nfs is not an option but the fs type ;) | 16:15 |
| oCean | oh right :) | 16:16 |
| oCean | heh | 16:16 |
| robo | oCean, mount -t nfs -a mounts it | 16:19 |
| robo | just not after a reboot. | 16:19 |
| robo | so the console is showing errors about how mountall failed. Before I get into why I'm trying to figure out how I get that same error when I'm ssh'd in to the machine | 16:32 |

| robo | is there a way to show what programs are going to start at which runlevels? A centos chkconfig --list equivalent is what I'm searching for | 16:42 |
| patdk-wk | there are no runlevels :) | 16:44 |
| robo | ? | 16:44 |
| robo | patdk-lap, that's something that confuses me too that I need to look into. It shows I'm in runlevel 2 -- that's strange to me | 16:44 |
| Calif | Hi, I'm attempting to run dhcpd - I'm running it and getting the following error: http://pastebin.com/TRp4TiQC | 16:45 |
| patdk-wk | ubuntu only has runlevels to keep compatability with old stuff | 16:45 |
| patdk-wk | but it doesn't *use them* | 16:45 |
| patdk-wk | the same with almost every distro now | 16:45 |
| Calif | RIP run levels :/ | 16:45 |
| robo | hmm | 16:46 |
| robo | so how do I know if my server is booted into a gui? | 16:46 |
| robo | normally if I see runlevel 3 I know I'm all text. Runlevel 5 I know I have X booted | 16:47 |
| patdk-wk | heh, a server with a gui is just pure evil :) | 16:47 |
| robo | i know. That's why I'd like to figure out if a gui is running | 16:48 |

| patdk-wk | ah, not installed | 16:50 |
| robo | so it's not running, which is good :-) | 16:50 |

| Pici | Defusal: What release of Ubuntu is that? | 16:51 |
| Defusal | 10.04 | 16:51 |
| robo | i guess if runlevel shows i'm in runlevel 2 then I look in /etc/rc2.d ? | 16:51 |
| patdk-wk | heh, I'm lazy to figure it out :) 'grep ^start /etc/init/*' | 16:51 |
| Pici | Defusal: Can you pastebin the output of: apt-cache policy mplayer ? | 16:54 |
| robo | man patdk-wk, ubuntu is so confusing | 16:54 |
| patdk-wk | heh, I don't think so :) | 16:54 |
| robo | i need to learn it | 16:55 |
| patdk-wk | I ran slackware for decades | 16:55 |

| ScottK | Defusal: You aren't trying to install the 10.04 version of mplayer. | 16:56 |

| dany | Does anyone know if Can i change the default url froom /webaccess to mail.domain.TLD ? | 16:59 |
| ScottK | robo: In many ways. Ubuntu Server will generally have newer packages than the most recently Debian release. Ubuntu uses apparmor by default instead of selinux.

| robo | any suggestions on why this is happening? | 18:10 |
| RoyK | start portmap | 18:10 |
| RoyK | or even - enable it | 18:11 |
| robo | I see rpc.statd running | 18:11 |
| robo | service portmap status shows portmap start/running, process 898 | 18:11 |
| RoyK | perhaps portmap is started after the nfs mounts? | 18:11 |
| robo | yeah, seems that way RoyK | 18:11 |
| robo | any suggestions on how to figure this out? | 18:11 |
| RoyK | which version are you on? | 18:12 |
| robo | 9.10 | 18:12 |
| RoyK | that's not supported anymore | 18:12 |
| robo | i know :-/ | 18:12 |
| RoyK | I'd upgrade to 10.04LTS | 18:12 |
| robo | guess as of last week | 18:12 |
| robo | that's where I was trying to decide if 11.04 or 10.04LTS | 18:12 |
| RoyK | there are far more users on LTS releases, so bugs are found and fixed quicker | 18:12 |
| robo | oh? Nice to know | 18:13 |
| RoyK | if it's just a server, I'd suggest 10.04LTS | 18:13 |
| robo | cool; ty for the suggestion | 18:13 |
| * RoyK has 20ish 10.04 servers running | 18:13 | |
| robo | nice! | 18:13 |
| robo | i have closer to 50 servers that will soon be ubuntu | 18:13 |
| RoyK | :) | 18:13 |
| robo | a bunch of solaris, ubuntu and centos right now | 18:14 |
| Pici | I use the latest Ubuntu release on all my personal computers (including my VPS), but for work stuff I stick with 10.04 | 18:14 |
| robo | I prob have around 15-20 ubuntu but they are all running 9.10 | 18:14 |
| RoyK | robo: we still stick with solaris^WOpenIndiana for storage | 18:14 |
| RoyK | ZFS FTW! | 18:14 |
| robo | We use Netapp here | 18:14 |
| RoyK | heh - that costs a bit more ;) | 18:14 |
| robo | yes, yes it does | 18:14 |
| Xpistos | I found the answer. motd not updateing so I deleted /etc/motd.tail - problem solved | 18:15 |
| RoyK | cost us some EUR 20k per 100TB box with supermicro hardware and openindiana on the top | 18:15 |
| robo | I just inherited all these ubuntu servers. I don't have a clue what i'm doing | 18:15 |
| RoyK | 100TB _net_ storage after a load of redundancy | 18:15 |
| robo | load of redundancy? Is that data de-duplication? | 18:15 |
| RoyK | no dedup - that's not really stable yet | 18:16 |
| robo | gotcha | 18:16 |
| RoyK | but redundancy as of small RAIDz2 VDEVs | 18:16 |
| robo | oh, right | 18:16 |
| RoyK | and with SSDs for caching, the boxes can sustain 10Gbps throughput, which is rather neat for a machine at that price | 18:17 |
| RoyK | s/a machine/machines/ | 18:18 |
| robo | so RoyK, any ideas how i can get portmapper to start before nfs? | 18:19 |
| robo | i'm not really sure how to adjust this type of thing in ubuntu. I don't think it's as easy as editing files in /etc/rcx.d | 18:20 |
| RoyK | robo: upgrade to 10.04 first - it might be fixed there, and it'll give you updates | 18:20 |
| robo | so you think it's just a bug? | 18:20 |
| RoyK | robo: ubuntu uses upstart for most stuff | 18:20 |
| RoyK | robo: yes | 18:21 |
| robo | upstart, let me look into that | 18:21 |
| RoyK | robo: it won't take too long to upgrade, though | 18:21 |
| robo | is there a recommended way? | 18:21 |
| RoyK | do-release-upgrade | 18:21 |
| robo | i was thinking I'd have to build a fresh O/S and move everything over | 18:21 |
| robo | oh, nice | 18:21 |
| RoyK | upgrading is trivial | 18:21 |
| JanC | just check the release notes etc. | 18:22 |
| robo | nice! :-) | 18:22 |
| JanC | and maybe try first with the least important one ;) | 18:22 |
| patdk-wk | janc that is defently not any fun | 18:23 |
| RoyK | patdk-wk: why? | 18:23 |
| robo | there is nothing fun. We use vmware | 18:24 |
| patdk-wk | to test it? before attempting it on production? :) | 18:24 |
| robo | So snapshot -> upgrade :-D | 18:24 |
| RoyK | yeah :) | 18:24 |
| RoyK | patdk-wk: coward! | 18:24 |
| JanC | if you have vmware you can probably just test on a copy too... | 18:24 |
| patdk-wk | ya, I'll clone, then test | 18:25 |
| patdk-wk | but only if I feel something will break | 18:25 |
| patdk-wk | and my guts don't work most of the time :) | 18:25 |
| RoyK | patdk-wk: for most servers, an upgrade won't even need a clone, so long as you have a snapshot | 18:25 |
| patdk-wk | well, it depends on how you test | 18:26 |
| patdk-wk | I'll play with it for a week or so | 18:26 |
| RoyK | depends more of what sort sort of server | 18:26 |
| robo | all our servers are N+1. So I snapshot it and pull it out of the F5 pool for testing | 18:27 |
| patdk-wk | so formal :) | 18:27 |

| RoyK | setting up mpich2 on them these days... | 18:33 |
| RoyK | dosen't ESXi support memory overcommit? | 18:33 |
| patdk-wk | royk, yep | 18:33 |
| patdk-wk | and memory dedup | 18:34 |
| robo | and does it nicely too | 18:34 |
| RoyK | for some stupid reason (price, that was, we're an institute, and get rather good prices from MS), my boss chose hyper-v over vmware | 18:34 |
| patdk-wk | but when each vm is running 4-8gigs of ram | 18:34 |
| RoyK | hyper-v is not for the faint-hearted | 18:34 |
| patdk-wk | oh, I setup hyperv once, cause well, we had win2008 lic | 18:35 |
| patdk-wk | the application failed to work properly in a win2003 hyperv guest | 18:35 |
| patdk-wk | really strange issue | 18:35 |
| patdk-wk | it was a webserver | 18:35 |
| RoyK | excessive network traffic seems to bring down the VMs on hyper-v | 18:35 |
| patdk-wk | ya :) | 18:35 |
| RoyK | there's a hotfix available now, though - the MS guys installed that on one of the nodes today | 18:36 |
| patdk-wk | the hyperv guest would get the http headers, and send a reply, but the reply would never make it to the network wire | 18:36 |
| patdk-wk | I dumped hyperv after that | 18:36 |
| RoyK | hehe | 18:36 |
| patdk-wk | between that and lack of memory overcommit | 18:36 |
| patdk-wk | my san just arrived at my house last week, haven't had any time to set it up though :( | 18:37 |
| === medberry is now known as med_out | ||
| RoyK | I don't get why MS hasn't figured out memory overcommit | 18:37 |
| * patdk-wk starts playing with 8gb fc at home :) | 18:37 | |
| RoyK | patdk-wk: probably useful in the winter, if you live in a place where it gets cold :P | 18:37 |
| patdk-wk | hehe | 18:38 |
| patdk-wk | I already hack a shelf of servers that are all poe | 18:38 |
| patdk-wk | thinking about converting them all to san boot, diskless poe test machines | 18:38 |
| patdk-wk | hmm, not poe, but wol | 18:38 |
| adam_g | \ | 18:40 |
| RoyK | wol? | 18:42 |
| Pici | Wake On Lan | 18:42 |
| RoyK | k | 18:42 |
| RoyK | but poe can't really drive a PC, can it? | 18:43 |
| JanC | maybe if it's an ARM blade, but AFAIK those are not available yet ;) | 18:43 |
| RoyK | 25.5w for a PC seems a little low | 18:44 |
| JanC | RoyK: depends on what "PC" | 18:44 |
| RoyK | for an ARM or Atom, perhaps | 18:44 |
| JanC | there are x86 SoCs that run at 1 W (GPU included) | 18:44 |
| RoyK | SoCs? | 18:45 |
| JanC | but I doubt those are used a lot in servers, outside of small home servers | 18:45 |
| JanC | SoC = System-On-a-Chip | 18:45 |
| JanC | basically most of your motherboard integrated in 1 chip, like they also use in smartphones etc. | 18:46 |
| RoyK | ah - ok - but I don't think those will be much fun if you try to start a 3D game on them | 18:46 |
| JanC | well, old 3D games should be possible ;) | 18:46 |
| JanC | and the x86 SoCs I know have much worse 3D GPU than high-end ARM SoCs | 18:47 |
| * RoyK likes ARM | 18:48 | |
| RoyK | this guruplug is rather neat | 18:48 |
| JanC | RoyK: you can play Full HD video on some ARM SoCs nowadays | 18:48 |
| RoyK | I know | 18:48 |
| RoyK | HTC Desire HD with HDMI output.... | 18:49 |
| * RoyK goes to find his old C128 | 18:49 | |
| JanC | or a PandaBoard ;) | 18:49 |
| JanC | but there is a company working on 4-core & more ARM SoCs for blade servers AFAIK | 18:49 |
| RoyK | aren't ARMs rather slow on FP? | 18:50 |
| JanC | I guess that depends | 18:50 |
| RoyK | also, even if you can pack them more densely than, say, Opterons, there's still a cost of splitting jobs into smaller and smaller pieces | 18:51 |
| === NG_ is now known as ng_ | ||
| JanC | ARM just defines the main CPU architecture, and in recent designs they have some SSE-like instructions, but you could probably use specialised co-processors if you need heavy FP (similar to the DSP they use to decode video) | 18:53 |
| JanC | RoyK: that depends on the type of job of course | 18:53 |
| RoyK | met stuff | 18:53 |
| RoyK | windfield simulations etc | 18:53 |
| JanC | your users probably know best how well they can parallellize that ;) | 18:54 |
| patdk-wk | royk, I didn't mean poe, I meant to say wol instead, keep the rack of computers off, unless I need them :) | 18:54 |
| RoyK | :) | 18:54 |
| patdk-wk | but the ones I'm using are 2.6ghz p4's, and use about 46watts | 18:55 |
| JanC | except on boot, I guess? :P | 18:55 |
| patdk-wk | why? | 18:55 |
| patdk-wk | no harddrives :) | 18:55 |
| patdk-wk | shouldn't use *that* much more on boot, I think the psu on them is 90watts | 18:55 |
| JanC | then you are wasting a lot probably | 18:57 |
| RoyK | wasting what? | 18:57 |
| JanC | 90 W PSU's (and certainly older ones) probably aren't very efficient at 45 W | 18:58 |
| === ng_ is now known as NG_ | ||
| patdk-wk | well, lets say it this way | 18:59 |
| RoyK | IIRC most PSUs are most efficient at about 50% load | 18:59 |
| patdk-wk | I dunno how much power the computer is using | 18:59 |
| patdk-wk | the PSU draws 45 watts :) | 18:59 |
| RoyK | or was that 30%? | 18:59 |
| patdk-wk | my watt meter on the 120v line going to the psu says 45watts :) | 19:00 |
| patdk-wk | how strange of me also, my workstation runs on 230v, but I haven't ran a 230v line to the *rack* | 19:01 |
| RoyK | most PSUs today take anything from 100 to 250V | 19:02 |
| patdk-wk | yep | 19:02 |
| patdk-wk | I have always found 120v power annoying, and neutral wires even more annoying | 19:02 |
| * RoyK just read about the .jp power grids - there are two of them! 50Hz and 60Hz | 19:03 | |
| patdk-wk | oh? are they converting to 50hz? | 19:03 |
| patdk-wk | japan has always been a strange mix of usa and eu standards | 19:04 |
| RoyK | the north runs on 50Hz, where the south runs on 60Hz | 19:04 |
| RoyK | both on 110V, though | 19:04 |
| RoyK | I don't see the point of running 110V systems when 380/400V systems are so much flexible | 19:05 |
| patdk-wk | I don't see the point of 110v since a neutral is a waste of a power wire | 19:07 |
| aBs0lut30 | hey guys, anybody had any luck getting any of the newer(SCST,LIO) iscsi targets working?? | 19:25 |
| aBs0lut30 | on natty that is... | 19:25 |
| aBs0lut30 | I can get SCST running but as soon as I attach vmware to a lun it wigs out... lio, well I cannot even come close to making that one work | 19:26 |
| Calif | Hi, I'm trying to get dhcpd running. I am getting a permissions error when attempting to create the pid file. See: http://pastebin.com/TRp4TiQC | 19:28 |
| ppetraki | aBs0lut30, how about a Linux client? does it react the same way? | 19:28 |
| Calif | I have done a chmmod 777 /var/run | 19:28 |
| Calif | removed the old pid file | 19:28 |
| Calif | and i still get the permission error when I run dhcpd | 19:28 |
| aBs0lut30 | ppetraki: havent tried a linux client, but the win7 client seems to work just fine... | 19:29 |
| patdk-wk | well. lio is new, I don't believe it's suppost to be that *stable* till kernel 2.6.42 | 19:29 |
| aBs0lut30 | ppetraki: and I should clarify, I can connect vmware to the target, but as soon as I try and format a lun to VMFS it just hangs the server | 19:29 |
| ppetraki | aBs0lut30, so LUN discovery, with any transport, is usually free of block level access | 19:30 |
| aBs0lut30 | am a bit curious as to why IETD is still the "default" iscsi package at this point... its a complete POS... IMHO | 19:30 |
| ppetraki | aBs0lut30, e.g. connecting and writing to it are two separate things | 19:30 |
| ppetraki | aBs0lut30, the win7 client, can you perform IO? | 19:30 |
| aBs0lut30 | not much, but I partitioned and formated a lun with no problems | 19:31 |
| aBs0lut30 | on the vm side, I do see a TON of command aborts once it tries to start writing to the lun | 19:32 |
| ppetraki | aBs0lut30, well, that's sufficient, a handful of reads and writes | 19:32 |
| ppetraki | aBs0lut30, so that tells me the Linux iSCSI server side of things isn't disfunctional | 19:32 |
| aBs0lut30 | yeah its really odd... | 19:33 |
| aBs0lut30 | ohh, there is one more thing... let me pastebin this real quick... | 19:33 |
| ppetraki | aBs0lut30, I was just about to ask for logs :) | 19:33 |
| aBs0lut30 | http://pastebin.com/4Xszaxs5 | 19:33 |
| aBs0lut30 | that is a fault I saw pop up once... | 19:33 |
| aBs0lut30 | let me grab some of the regular logs and throw out there as well... | 19:34 |
| ppetraki | aBs0lut30, oh, vmware running on Linux, I automatically thought ESX :-p | 19:34 |
| aBs0lut30 | well it is ESX | 19:34 |
| aBs0lut30 | that fault is from the SCST side | 19:34 |
| ppetraki | yeah, that looks real | 19:35 |
| aBs0lut30 | http://pastebin.com/cLrBkbB2 there is a snap of the dmesg output from SCST after I connect to the lun | 19:35 |
| ppetraki | aBs0lut30, task wakes up to process a command and looks like it dies doing some refcount housekeeping | 19:36 |
| ppetraki | aBs0lut30, bug it | 19:36 |
| ppetraki | aBs0lut30, sorry :( | 19:36 |
| aBs0lut30 | me too :( stuck with the crappy IETD I guess... which sucks cause ESX is killing it like once a day... | 19:37 |
| ppetraki | aBs0lut30, IETD? what's that? | 19:37 |
| aBs0lut30 | the old iscsi enterprise target... | 19:37 |
| aBs0lut30 | aka the iscsitarget package | 19:37 |
| patdk-wk | I have only started playing with scst last week | 19:38 |
| patdk-wk | plan on doing a lot of it soon, but didn't plan on much iscsi with it, mainly going use it for fc lun's | 19:39 |
| aBs0lut30 | if I could get it to work, SCST looks pretty easy to use... | 19:39 |
| aBs0lut30 | and from what I read/hear it works pretty well too... | 19:40 |
| ppetraki | aBs0lut30, I know lots of about SCSI, haven't really had the opportunity to play with iSCSI yet though | 19:45 |
| ppetraki | aBs0lut30, I can tell you though, that emulating a SCSI target is one of the most difficult things you can attempt in storage | 19:46 |
| aBs0lut30 | heh, and I am pretty much the other side of that coin... | 19:46 |
| aBs0lut30 | yeah... I can tell, hah | 19:46 |
| ppetraki | aBs0lut30, this doesn't sound like a terrible bug, I'm surprised we didn't catch this in regression testing | 19:47 |
| patdk-wk | oh? scst is included in natty? | 19:47 |
| aBs0lut30 | well, wouldnt be supprised to find out its something strange in my setup that is causing it... | 19:47 |
| aBs0lut30 | patdk: not really... | 19:47 |
| ppetraki | aBs0lut30, if your clients obey the SCSI spec well enough, which I expect as much from VMware, then it's likely the target emulator screwed up somewhere in the translation | 19:48 |
| aBs0lut30 | based on what I am seeing that would sound about right... would love to know what the win7 client is doing that lets it work... | 19:50 |
| ppetraki | aBs0lut30, that lets the win7 client run up until this point :). put some stress on that with iometer and I think you'll come to the same conclusion | 19:50 |
| aBs0lut30 | plus I had to jump through a number of hoops to get SCST to build/load... and one of the patches for the 2.6.38 kernel wont apply correctly... so there is no telling | 19:50 |
| ppetraki | aBs0lut30, ooooh, now I get it :) | 19:51 |
| aBs0lut30 | yeah, forgot about that patch not going on until just now... | 19:51 |
