=== erichammond1 is now known as erichammond === GhostFreeman__ is now known as GhostFreeman [01:37] hmm, I got the same serial-console panic. Now, what was I supposed to do to debug it? [01:38] Or rather, it's not a panic, because at least ZNC is up. [01:38] Yet, ssh is dead. [01:38] Should I just try a 3.x kernel? [01:40] Going to reboot. [01:53] anyone know what I need to do so I can copy UFW rules between servers? [01:58] okay, I'm going to try 3.0.4 kernel. [01:58] Not trying 3.1 until it's out of RC, since this is my server that I need to have stable. [02:04] DanaG: I'm running 3.0.4 on my desktop at work. I really like it. The 3.0.4 kernel is very stable [02:09] squidly: look in /lib/ufw, there should be a user.rules file you can copy over [02:11] and how to I activate it? [02:12] say, how do I disable the auto-blanking of tty0 (uvesafb)? === erichammond1 is now known as erichammond [02:16] danag, looks like it's an asci thing [02:16] http://www.linuxquestions.org/questions/linux-server-73/how-to-disable-console-blanking-in-text-mode-780272/ [02:18] ALso fiddling with serial console while I'm at it. [02:19] Stupid HP... uses an IPMI chip that supports SOL, but doesn't expose that serial port. [02:19] So I have to have a PCIe-1x serial port card. [02:19] why not use ipmi over ip? [02:20] Well, what I mean is: I got the HP remote access card for my Microserver, and there's no serial-over-LAN feature. There's a java viewer, but that's no good for grabbing stacktraces and all that. [02:21] The IPMI chip itself, ASPEED AST2150, supports SOL... but HP's system BIOS doesn't expose it. [02:22] going to reboot the server (also happens to have ZNC on it). [02:27] http://pastebin.com/85CNMLK5 [02:27] okay, so, grub doesn't like the pcie serial. [02:27] Unknown serial port. :( === lullabud is now known as warzauwynn [02:38] dangit, zfs modules don't like 3.0.4. === DanaG_ is now known as DanaG [02:41] http://pastebin.com/85CNMLK5 [02:41] there's the serial console oops. [02:43] I'll be swtiching to btrfs as soon as it has a fsck that'll fix things. [02:43] heh, isn't that scheduled for sometime within the next 5 years? [02:44] it just seems like play toys are more important for btrfs currently, than stability [02:53] Byobu doesn't work over serial: [02:53] strace: http://paste.ubuntu.com/700831/ [02:56] DanaG: That looks like a permissions issue on /var/run/screen, notthing related to it being a serial connection, to me ... ? [02:56] What's weird is that the same permissions work fine over ssh. [02:57] And the same sort of hang happens with aptitude, I think. [02:57] I'll pastebin a strace of aptitude. [02:58] heck, even fgconsole hangs. [02:58] open("/proc/self/fd/0", O_RDWR [02:59] And in fact, aptitude hangs when run normally, but when redirected to strace, it shows colors for a moment. [03:00] DanaG: For the aptitude ncurses UI to work, you would need an appropriate termtype set, is that (part of) the issue?? [03:01] $TERM is "linux" [03:01] http://paste.ubuntu.com/700835/ [03:01] there's aptitude. Did 2>aptitude.txt and then gave it sigquit when it hung. [03:01] Then sent the contents of aptitude.txt to pastebinit. [03:08] Are you on ttyS5 ? That looks like it looked at at /dev/tty0 and then tried to open /dev/ttyS5 and ... it all ended! I'm guessing, but you could check permissions on both /var/run/screen and the serial device (/dev/ttyS5 or whatever it really is). [03:13] The second trace is just running aptitude, so screen is out of the picture. [03:13] And yup, the serial console is ttyS5. [03:13] There's no 0 or 1 or 2 or 3.... just 4 and 5. [03:19] hmm, even as root, aptitude hangs the same way. [03:20] Any difference if you do export TERM=vt100 ; reset $TERM first? [03:28] What is the output from the following on an ubuntu server's portmapper?: strings /sbin/portmap | grep hosts [03:28] I'm looking specifically at 10.04, but any would do at this point. Thanks! [03:29] jmarsden: yup, that gives me a monochrome aptitude. [03:29] Oddly, exporting TERM=screen works, as well. [03:29] Though, it does use this on the "quit?" dialog: [03:29] lqqqqqqqqqqqqqqqqqqqqqk [03:31] DanaG: OK. So the issue was the termtype... good. Now you need to figure out what termtype your terminal "really" is so you can set one that works 100%. It's been 15 years since I worked with termcap and termtype :) [03:37] dangit, same oops on closing serial console. [04:50] good, 2.6.39 seems to work. [05:06] I'm setting up ubuntu server 11.04, and I keep getting "Don't seem to have all the variables for eth0/inet" when I try to 'sudo ifup eth0'. I'm following the ubuntu server guile page for this [05:07] can anyone help me set up a pptp vpn [06:24] Hello, does anyone have a link to a good guide on how to connect to VPN (I'm using OpenVPN) via command line in ubuntu server? [06:38] iggi_: It is not Ubuntu-specific, but the OpenVPN Mini-HOWTO for a really basic setup is at http://openvpn.net/index.php/open-source/documentation/miscellaneous/78-static-key-mini-howto.html [06:40] jmarsden, Thanks, I'm just trying to figure out how to setup multiple VPN connections on a monitoring server to monitor hosts behind firewalls at various locations [08:11] New bug: #864495 in samba (main) "package samba-common 2:3.5.4~dfsg-1ubuntu8.4 failed to install/upgrade: there is no script in the new version of the package - giving up" [Undecided,New] https://launchpad.net/bugs/864495 [08:51] is it possible to have a usb webcam live feed on ubuntu server without installing gui? [09:00] D0minat0r, I think vlc can do that [09:00] D0minat0r, that is where I would look [09:13] smw: ok thanks will look into it [09:26] Hi I'm not sure if this is making sense but: For our current domain I have set up google apps and am using google's mx records for email [09:27] but now I'm setting up an smtp server on our server as well, which I only want to use for our automatic mails sent through PHP [09:28] does that make sense? and does it require a new mx record or should I keep the hostname in the settings the same as the IP? [10:37] is TLS good to set up, even if postfix is set to a null configuration? [10:48] what ? [10:48] null configuration ? [10:48] "good to setup" ? [10:48] Dulcin: any chance you could try to re-ask that question explaining a little better ? [10:55] Hi. My postfix is not listing auth capability after tls/ehlo. I’m trying to use dovecot sasl. no helpful information in error log. I’m hoping someone can offer advice. postconf -n http://pastebin.com/yrpCe7jf and dovecot -n http://pastebin.com/LpkxQtBz IMAP/dovecot itself is working. [10:55] dnmons: dovecot and postfix are two seperate things, which one is not working [10:56] ikonia: I assume dovecot is working just fine. as authenticating against it works. and it is the smtp connection that is not offering auth capabilities. [10:57] so forget dovecot, just focus on postfix [12:06] ikonia: Well, I took that 'null setup' from the postfix documentation, let me try and explain what I want [12:08] ikonia: I currently have Google Apps set up which handles all the mail. But now I want our website to send mail securely as well. So I set up postfix, and since I only want the webserver to send mail (and not receive) I figured I can set it up in a 'null client'* [12:09] At first I tried to set it up with SASL and try sending with TLS, but I couldn't get that to work and while reading up on postfix, I noticed the null client might even be better [12:09] so my questions was... [12:09] does my mailserver need its own mx record, or since I'm only sending mail, it is obsolete [12:10] and can I leave the TLS/SASL/certificate, etc. out of my setup, if it is only set up as a 'null client' [12:11] ikonia: like: since nobody else can use it anyway (i think), I dont need to add an extra security layer [12:11] maybe I'm way off with my reasoning [13:32] is virtualized ubuntu inside ubuntu fast? [13:34] I'm using 11.04 now but need 10.04LTS because it supports my new raid adapter [13:38] Olotila: some things are very fast when virtualised using hardware that assists virtualisation, other things get more of a performance hit, and there are also differences between virtualisation technologies, so there is no simple answer to your question ☺ === JanC_ is now known as JanC [13:39] also, why doesn't 11.04 support your raid adapter? [13:39] (and why don't you use software raid instead?) [13:43] not sure why, it is adaptec 6805E and they boast about their support for Linux [13:43] gave "too many errors" when I tried [13:44] I use hw raid because I use both windows and linux [13:44] I used mobo raid (intel ich10r) but it's not supported in linux [13:45] if I used sw raid it would not work in windows [13:47] my virtualized usage would be almost 100% usual surfing and getting to know Ubuntu [13:47] using max 10% of my current PC resources [13:48] 4(+4) cores, 6GB ram [13:54] Olotila: 11.04 isn't too good a choice for servers anyway [13:54] Olotila, if you're really that concerned about performance, go ahead and install 10.04 to the RAID and the use a recovery CD [13:54] Olotila, from the recovery CD, chroot to your RAID, and then install a "backports LTS" kernel, like the Natty one [13:55] Olotila, which should get you the HW support you desire [13:55] Olotila: that ich10r raid controller isn't a real raid controller [13:56] RoyK, he's got an Adaptec too [13:56] ppetraki: so I saw - just wanted to comment on that intel thing [13:56] Olotila: i'm running a few VMs virtualized with kvm - works like a charm [13:57] one of the VMs is running Zimbra, which can be a bit on the heavy side [13:57] still works well, on an old core2 duo [13:57] Olotila, just confirmed that there is a "natty lts backport" package: linux-image-server-lts-backport-natty [13:58] ppetraki: why would he need that? [13:59] RoyK, so he could run 10.04 on baremetal [13:59] why can't he just use the lucid kernel? [13:59] RoyK, iif he's *that* concerned with performance [13:59] newer kernel != better performance [14:00] RoyK, " I'm using 11.04 now but need 10.04LTS because it supports my new raid adapter" [14:00] 'cept with oneiric comes xen, which is a wee jump in performance [14:00] RoyK, implies 10.04 doesn't support that HW [14:00] ppetraki: what he said there was that 11.04 didn't support his hardware [14:01] Olotila: can you clear this out, please? does 11.04 support your hardware? [14:01] RoyK, that doesn't make sense. how does a older release have the hardware enablement he needs? [14:02] bugs do happen [14:02] well, that would be a bug :) [14:02] * RoyK even sticks to hardy on some machines [14:03] there might be a closed source driver for LTS or something... [14:05] Olotila: if you just want to do surfing with Ubuntu, why don't you run an Ubuntu VM on your existing Windows? ;) [14:05] in any case, performance probably won't be an issue for surfing [14:08] RoyK, it looks like the aaraid driver but I can't find a hit for that product id in the pci ids list, in either lucid or natty [14:08] even a 400 MHz machine with 256 MiB of RAM is fast enough for surfing... [14:08] oh - same old pci id issue [14:09] Olotila, could you provide a pci id for the Adaptec card? [14:09] JanC: erm - that depends where you surf :P [14:09] * RoyK thinks Olotila has fallen asleep [14:09] :) [14:10] Adaptec provides a dkms for "debian 5 and Ubuntu 10.04", even a package for the installer [14:10] RoyK: maybe if you want to play Doom ported to WebGL & JavaScript that is not enough, but basically for every other website it's plenty ;) [14:11] JanC: add some java and flash and html5 and js and whatever's in use out there, and your 400MHz machine will choke itself before you get the average news site opened [14:11] most news sites work fine without JavaScript actually ;) [14:13] * RoyK just got a pandaboard - little single board thing with a dual-core Cortex A9, some helper cores at 266MHz, 1GB RAM, wifi, SD card and cameras connectors, dual HDMI out, total <$200 [14:14] no need for some old power-consuming 400MHz beast then... [14:14] right, I was just talking about what performance is really *needed* [14:15] that depends on use [14:15] what about your average dual-core 1GHz coretex9 in your new phone? ;) [14:16] btw, this is rather fun http://pandaboard.org/ [14:17] even a simple single-core Cortex A8 can play full HD movies while surfing all you want... (your pandaboard has 4 cores!) [14:17] yeah, but only two general purpose-cores [14:17] the smaller ones must be programmed with specific API calls [14:18] it has 4 GP cores IIRC, but 2 of them are very slow (but also consume almost no power)? [14:18] but fine for offloading simple stuff like controlling a camera without waking up the main cores [14:18] might require special API calls indeed [14:18] they do - I checked... [14:19] but I guess that also depends on the OS [14:19] well, it's probably possible to have the OS handle that, but I really don't want to start to rewrite the linux scheduler [14:19] and of course it also has several special purpose cores [14:20] for encoding/decoding video, for graphics, etc. [14:20] basically, it's more advanced than your desktop processor ;) [14:22] it's neat :) [14:23] the only disadvantage being that there is no proper driver for the GPU core... [14:25] personally I'd rather see a similar board with s BTW ☺ [14:25] personally I'd rather see a similar board with lots of SATA adapters BTW ☺ [14:25] indeed :D [14:26] I wonder... [14:26] would be great for building a NAS / home server [14:26] and maybe you could off-load RAID computations to the low-power cores [14:27] and maybe also encryption [14:27] those A9s would do well for that [14:27] both disk & network encryption [14:28] it should be possible to create a fantastic A9 and/or A15 based SoC for home/SoHo servers [14:29] * patdk-lap wonders if the market for one is high enough [14:30] patdk-lap: if I see how many NAS are sold currently, there should be [14:30] JanC: AFAICS the only interface for mass storage on the panda is usb [14:31] RoyK: I know, I looked at it as a possible replacement for an existing NAS ;) [14:32] there is no proper PCI interface to extend it either [14:32] PCIe [14:32] and the GPU is useless for that purpose [14:33] so obviously OMAP SoC's are designed for another purpose [14:33] I just asked on #pandaboard and was told [14:33] drscott> RoyK - I have not found a sata interface for the panda board - however the freescale i.mx53 quick start board has a chip-supported sata port [14:34] that's what is used in the "Plug" computers IIRC? [14:34] dunno [14:34] or at least something like that [14:34] * RoyK checks lshw on his guruplug [14:35] hm.. nothing there [14:35] Hello [14:35] RoyK: nothing in /proc/cpuinfo either? [14:37] http://paste.ubuntu.com/701061/ [14:37] btw, if you ever get a guruplug or similar, don't try lucid on it :P [14:38] royk, heh, oi fell completely over when I attempted to use both my ib interfaces at once :) [14:38] wtf? [14:39] I was getting about 350MB/sec over both ib links, one at a time, if I used both at the same time 36MB/sec [14:39] ouch [14:39] had to do some /etc/system tweaking, and it's getting me a good 800MB/sec over both now :) [14:39] neat [14:39] at the same time [14:40] what sort of ib? [14:40] just 10g currently [14:40] I didn't know there was a 10g [14:40] heh? normal is 10g 20g and 40g [14:40] or 8/16/32... [14:41] for throughput rates [14:41] ah [14:41] ic [14:41] signalling rates is what they go by, like with FC [14:41] ic [14:42] patdk-lap: mass storage? [14:42] attempting to replace a netapp [14:44] looked like iscsi fixed all my random seek test issues [14:44] so I will probably use a mix of iscsi and nfs [14:45] k [14:45] what sort of hardware/drives? [14:48] x8sia-f, 3.3ghz i3, 20 ultrastore a7k [14:48] i3??? [14:48] ya [14:48] wouldn't you want ECC on such a box? [14:48] it has ecc [14:48] only ecc is supported [14:48] i3 doesn't support ECC [14:48] you mean, registered is not supported [14:48] the memory controller in i[357] doesn't use ECC [14:49] you need a xeon for that [14:49] http://www.intel.com/support/processors/corei3/sb/CS-031175.htm#10 [14:49] ya, so ecc memory is required, but the ecc is not used [14:50] lol, what's the use for that? :P [14:51] I mean, having to buy expensive memory that has no benefits? [14:52] patdk-lap: the mobo may require ecc memory, but the memory controller, residing in the processor package, doesn't use it [14:52] well, it's only going be in use for a few months [14:52] patdk-lap: you're not the first to make that mistake - I had an i3 replaced by a xeon just a few months back :P [14:52] till it goes back offline again [14:53] data corruption can still be rather expensive [14:53] and a new Xeon to fit into that socket can be rather cheap [14:53] there are hundred of other places for datacorruption also [14:54] the new xeon is likely to be about the same price as one of the drives :P [14:54] looks like $350 for a 2.9ghz [14:54] still, that'll give you ECC [14:54] drives are like half the price of the cheapeast x34xx [14:55] what sort of disk layout? mirrors? [14:55] just mirrors [14:55] * RoyK thinks it's rather silly to give up ECC on such a system [14:56] a7k 2TB? [14:57] 1tb drives [14:57] don't need the space at all [14:57] database or VMs? [14:57] probably end up using it for crapload of snapshots [14:57] neither [14:57] email [14:57] k [14:58] 9-10TB for email sounds roomy ;) [14:58] currently using 1.6 [14:58] with dedup on that netapp? [14:58] but need the spindles [14:58] nope [14:59] some SSDs for caching as well? [14:59] it's a netapp that doesn't support anything than nfs [14:59] oh [14:59] ya, have ssd's on the way, think they got lost in shipping [14:59] netapp can't even support dedup if we wanted [14:59] old one? [15:00] fas270, not even a fas270c [15:01] so far my tests show good performance on everything, about 6x increase, excepted for that random seek test I was doing, but I can't replicate that test correctly currently [15:01] how much for the whole system? [15:02] just a SM 24slot chassis? [15:02] 4.6k about [15:02] USD? EUR? ISK? [15:02] usd [15:02] not bad [15:03] think I'm going use the 5k3000 for the next one [15:03] won't that be a bit low on the seek times? [15:03] 70 vs 81 per drive [15:04] but going put it into backup service [15:04] ppetraki, RoyK, JanC, sorry fell asleep ... nah, just rl stuff [15:04] to hold a mirror copy, and to stream to tape [15:04] adapter is Adaptec 6805E [15:04] when installling, it reports "too many errors" [15:04] thats why I started thinking other options [15:05] Olotila: that's on lucid? [15:05] patdk-lap: the 7k3000s aren't too expensive, though [15:05] performance is not the main issue [15:05] royk, ya, but 3g only :( [15:05] they are slowing down the whole bus [15:06] I rather go on native hw, and virtualization seems a little silly [15:06] patdk-lap: 7k2000? [15:06] I could cut my resilver time in half with 6g [15:06] but if that is way easiest, i could go that way [15:06] patdk-lap: the new 7k2000 are 6g [15:06] but if i get drivers to 11.04, that would be ideal [15:07] patdk-lap: Hitachi HDS723020BLA642 [15:07] natty lts backport seems to be "deleted" atm [15:07] I do have Ubunti in VM too, but I prefer native environment [15:07] Olotila: linux-image-2.6.38-11-server ? [15:08] royk, odd, they are not listed on hitachi's website, only 3g's [15:08] I have about 160 of those [15:08] this is 11.04 x64 desktop [15:08] Olotila: apt-cache search linux-image [15:09] heh, you guys have it backwards [15:09] patdk-lap: and they have written 6g on the drives [15:09] he wants to run a lucid kernel on natty :) [15:09] oh [15:09] Olotila: install lucid :P [15:09] royk, those are 7k3000's, not 7k2000 [15:09] still 2TB [15:10] bought 150 of them and got them for a little less than $100 a piece [15:10] s/less/more - $101,something [15:11] Olotila: sorry - is it the 11.04 kernel that complains about these errors, or the lucid kernel? [15:12] Royk, yeah, I did fail to install 10.04 to this hw [15:13] RoyK, yes [15:13] Olotila: latest 10.04.3 cd? [15:13] arg sorry, the 11.04 complains [15:13] yes, latest [15:14] erm.. does 10.04 or 11.04 complain? [15:14] * RoyK is slightly confused [15:14] 11.04 says too many errors [15:14] then don't use it [15:14] use lucid [15:14] meaning 10.04 [15:14] 10.04 does not install natively [15:14] oh [15:14] just hangs [15:14] try hardy ;) [15:16] i might try harder :) [15:16] hardy == 8.04 [15:16] still supported [15:17] i could try cd install instead of usb-stick, and a few different isos [15:17] it shouldn't make much difference installing from a CD or an USB stick [15:17] yeah, i know [15:18] *shouldnt, one of the ugliest words known to man :) [15:18] maybe... [15:18] i usually flinch when i hear "it should work" [15:19] :) [15:19] perhaps Oneiric beta? :) [15:19] is there any good advice when trying to install ubuntu and it does not want to complete the installation? [15:19] maybe the drivers are not included... [15:20] any general tips [15:20] Olotila: where in the installation does it hang? [15:20] Olotila: also, is this a desktop or server installation? [15:20] will not even show the ubuntu text and the five balls [15:20] desktop has far more bits and is harder to debug [15:20] either one would do [15:20] does the cd bootup fail? [15:21] or usb [15:21] or whatever [15:21] if so, try noacpi and noapic [15:21] as a start [15:21] it does not go very far, cannot even "try" ubuntu [15:21] iirc press f6 and you'll get those choices from there [15:21] Olotila: 'try ubuntu' implies you're installing desktop, not server [15:22] so server installs more likely, and I can better my odds with those choises I get with F6? [15:23] and disable acpi from bios? [15:23] just try server first [15:23] ok [15:23] it should be more verbose than desktop [15:23] does it write log somewhere? [15:23] meaning better at yelling at you === bastidra1or is now known as bastidrazor [15:24] no logs before the system is installed [15:24] but it'll log to the console [15:24] which should suffice [15:24] yeah [15:24] hmm, if the ubuntu with the balls appear, that means the kernel is done loading, and it's started the init scripts [15:24] so it's working [15:24] just some startup thing is holding it up [15:25] any difference between 32 and 64 bit? [15:25] Olotila: yeah, one is 32bit, the other is 64bit [15:25] dunno why you keep talking about the desktop install though, in the server channel [15:25] RoyK, i mean the odds of successfull installing [15:25] * RoyK hands patdk-lap a beer [15:25] Olotila: none whatsoever, if you're on a 64bit machine [15:26] patdk-lap, because I know here are pretty knowledgeable guys :) [15:26] Olotila: if you're on a 32bit machine, installing 64bit is quite likely to fail early :P [15:26] hehe, I have had all kinds of issues some machines [15:26] have a motherboard, that I put a 64bit cpu in, no issue [15:26] and i am installing server stuff too [15:26] but the motherboard refuses to boot any 64bit or even pae kernels [15:26] only worked in plain 32bit mode [15:26] Olotila: thing is, this channel is for the server _distro_, not the server bits [15:26] patdk-lap: wtf? something you got cheap on ebay? ;) [15:27] some msi neo motherboard [15:27] was only for a home desktop system [15:28] also had 4 memory slots, but you where only allowed to use 2 at a time [15:28] very strange motherboard [15:29] patdk-lap: hehe [15:30] Well, I'll try your advice and perhaps chat from within 10.04 server [15:30] thanks, thumbs up [15:30] patdk-lap: I've come by mobos that work well with either two or four memory modules, but clocked them down if all four were installed [15:30] Olotila: break a leg :) [15:30] royk, that is normal on all intel mmu systems [15:31] oh [15:31] it is? [15:31] the intel memory thing, has channels, and each channel supports 2 or 3 sticks [15:31] depending on if it's desktop or server model [15:31] if you use and adition stick, for 3 or 4, then the bus goes 800mhz instead of normal [15:31] or if you use qrank memory [15:32] nice if you need bulk memory [15:32] bad if you need to access memory quickly [15:32] so I guess we should have bought fewer, larger modules for our compute nodes? [15:33] as long as they where dual rank sticks [15:33] quad [15:33] it's opteron [15:33] dunno about opteron [15:33] but quad rank normally will slow any intel system down to 800mhz, and you can't use the extra slot [15:33] how can i see a list of running services? [15:34] but then, with quad, we get a bit wider memory buses than on xeon [15:34] KM0201: ps axf [15:34] heh? [15:34] quad what? [15:34] RoyK: thats a little to detailed [15:34]
